Description
The application relates to a divisional application, the application number of the original application is CN202311526173.2, the application date is 2023.11.14, and the application mainly relates to an efficient automatic water drill processing device.
Technical Field
The application relates to the field of water drill processing production, in particular to a high-efficiency water drill automatic processing device.
Background
The crystal diamond is also called crystal diamond and rhinestone. The main component of the water drill is crystal glass, and the water drill is an accessory for ornaments, which is obtained by cutting artificial crystal glass into diamond facets, and is popular among people because the material is economical and has a diamond-like eye-catching feel in visual effect, and is widely applied to low-and-medium-grade ornament design, so the water drill is mainly processed in batches.
The patent CN104551915B discloses a full-automatic water drill polishing machine, which discloses a first polishing production line and a second polishing production line which are arranged in a back-to-back manner, wherein two sides of the two polishing production lines are connected by adopting a rotating device, and two rubberizing powder stations are all arranged at the starting end of the production line. In the process of processing the water drill, the water drill in any production line is circulated through a common driving device, and the needle bar (the clamp is called as a patent) is circulated among a plurality of stations in sequence to finish the grinding and polishing processing of the water drill. Although the common time of needle bar circulation is the same, the time spent by different working procedures is different due to different execution operation and quality requirements, so that the residence time of the needle bar at different working stations is different, and in order to ensure the normal circulation of the whole production line, the machine position with the longest working station residence time can be used as the production beat of the whole production line, thereby leading to longer one-time processing time of the water drill due to the existence of bottleneck working procedures and further restricting the production efficiency and the yield of the water drill. In addition, the grinding process and the polishing process have requirements on the time of the water drill processing, in particular, the polishing process directly affects the quality of the water drill when the grinding or polishing time is insufficient.
It is worth to say that, for the full-automatic water drill processing production line, since the whole production line is in a production state without stopping, the production takt (single processing time of the longest processing station) means money, the longer the production takt is, the lower the water drill processing efficiency is, the lower the yield is, and conversely, the longer the production takt is, the higher the water drill processing efficiency is, and the higher the yield is.
Disclosure of Invention
Aiming at the technical problems that the production efficiency of the water drill is low and the balance of the production efficiency and the output quality is difficult to control due to overlong production beats in the water drill production line with the double-line circulation processing structure, the application provides the high-efficiency water drill automatic processing device which at least has the advantages of high processing efficiency, sufficient yield, controllable yield and the like.
The application provides a high-efficiency water drill automatic processing device which is arranged into a double-line circulation processing structure and comprises a turntable, viscose glue, feeding, grinding, polishing, high-frequency heating and discharging machine positions, wherein the high-efficiency water drill automatic processing device comprises:
Before the feeding machine position is arranged on the turntable machine position, the needle row enters the turntable machine position through the driving of the driving mechanism after the feeding machine position finishes clamping the bead blanks;
The rotary operation means that after the needle row entering the starting end is driven by a driving structure of one operation line to enter a grinding procedure, the rotary table rotates for 180 degrees to restore and waits for the next needle row to enter the rotary table machine;
The flushing procedure is integrated in the turntable machine position and comprises a water outlet structure, wherein a water outlet of the water outlet structure is arranged at the starting end of the other rotary line and is positioned before entering the grinding procedure.
Specifically, one of the concepts of the application is to use various processing cooperation structures of the existing water drill production line, and to eliminate bottleneck processes in the process of an automatic processing device by optimizing the process positions and the machine position layout, reduce the time length of production beats and improve the processing efficiency of the water drill, thereby achieving the purpose of improving the water drill yield.
Firstly, the gluing process is stripped from the turntable machine, so that the turntable machine only performs rotation operation or rotation operation, the gluing operation is not additionally performed, the operation execution complexity of the turntable machine is reduced, the station time of the turntable machine is only related to basic needle row driving and rotation operation, the production takt of the whole production line is balanced, the time of the production takt is reduced, and the production efficiency is improved. Meanwhile, the application integrates the flushing process without occupying station time into the turntable machine position, fills station gaps caused by stripping of the viscose process, ensures that the whole double-line circulation processing structure does not need to additionally increase the machine position, and avoids unreasonable rising of cost.
Further, any one of the processing lines is sequentially arranged into a viscose machine position, a feeding machine position, a rotary table machine position, a coarse grinding machine position, a fine grinding machine position, a first polishing machine position, a second polishing machine position, a high-frequency heating machine position and a discharging machine position, and the discharging machine position of one processing line is connected with the viscose machine position of the other processing line to form a double-line circulation.
In particular, the application belongs to a double-line circulation processing structure, and under the condition that the machine position meets the process requirement, the circulation closing of processing is realized by the mode that two processing lines are connected end to end, so that the space utilization rate of the high-efficiency water drill automatic processing device provided by the application is improved.
Further, the installed position of the turntable machine position is moved to a direction away from the rough grinding machine position, and the length of the needle row is extended on the basis of the original size of the needle row, so that the needle row reaches the maximum allowable length of the rough grinding machine position.
In particular, the present application is further conceived to eliminate the need for a turret machine station for the gluing process based on the adjustment of the production line structure, so that the drive time of the needle row can be adjusted in the case of a turret machine station with a dwell time comprising only a rotation or swivel operation time, plus the needle row drive time. The distance of the needle row moving is balanced in a needle row lengthening mode, and the processing capacity of the bead embryo at one time is improved.
It is worth noting that the water drill yield is related to the production takt and the water drill one-time clamping quantity, and the more the number of the water drills clamped by the needle row one time is, the higher the water drill yield is. Therefore, based on the adjustment and optimization of the structure of the automatic processing device of the water drill, the length of the needle row can be maximized, and the purpose of improving the processing yield of the water drill is achieved.
In some embodiments, the operation time of the rotary table machine position is taken as the beat standard of the processing line, the standard beat R X＝SZ+SA is preset, the grinding wheel diameter D 1 of the rough grinding machine position is obtained according to the standard beat and the processing length L of any surface of the water drill, and the production time Ry of the rough grinding machine position is enabled to be equal to S Z+y+ta≤RX;
n is the number of facets of the water drill, L is the processing length of any facet of the water drill, N 1 is the rotation speed of the grinding wheel, t a is the minimum feeding time allowed by the needle bar, R X is the reference beat, S Z is the shortest time for driving the needle bar to move from one machine position to the next machine position, S A is the time required for completing one rotation operation/rotation operation of the turntable machine position, and y is the preset processing time of the rough grinding machine position.
Specifically, through the adjustment and optimization of the layout of the whole automatic processing device, the turntable station becomes the optimal production takt reference machine position in all machine positions, and as the rotation operation or the rotation operation is only needed except for the common needle row driving operation, the time of the rotation operation or the rotation operation cannot be further optimized, so that the operation time of the turntable machine position becomes the preset reference takt R X. At this time, in order to further reduce the tact, it is necessary to reduce the operation time of the viscose, the feeding, the rough grinding, the fine grinding, the first polishing, the second polishing and the discharging from the viscose, the feeding, the rough grinding, the fine grinding, the first polishing, the second polishing and the discharging. Therefore, another concept of the present application is to reduce the grinding operation time of the rough grinding mill by increasing the size of the grinding wheel of the rough grinding mill, and to obtain the minimum grinding wheel diameter size based on the consideration of the grinding wheel rotation speed and the grinding quality so that the grinding wheel diameter satisfies the requirement of balancing the beats.
It should be noted that, t a is the minimum allowed feeding time of the pin row, which means that the grinding surface of the grinding wheel at the coarse grinding machine position is set at a position close to the pin row, so that the feeding distance of the pin row is minimized, and further, the feeding time of the pin row is minimized.
Further, the application provides a high-efficiency water drill automatic processing device, which comprises the following steps:
S1, presetting feeding speeds of all machine positions according to preset reference beats R X, so that actual processing time of a viscose machine position, a feeding machine position, a coarse grinding machine position, a fine grinding machine position, a first polishing machine position, a second polishing machine position and a discharging machine position is S 1、S2、S3、S4、S5、S6、S7 respectively;
S2, acquiring actual processing time and actual yield of each machine position in real time, wherein the actual processing time and the actual yield are S 1′、S2′、S3′、S4′、S5′、S6′、S7′ and y 1、y2、y3、y4、y5、y6、y7 respectively;
S3, taking the ratio of the reciprocal of the actual yield as the adjustment weight to obtain the actual reference beat R X′,
And S4, adjusting the feeding speed of each machine position in real time according to the actual reference beat R X′.
Specifically, the application has the further concept that the feeding speed of each machine position is regulated in real time through the actual yield and the actual processing time, the yield and the production beat of each machine position are balanced, and the yield of the water drill processing is ensured while the production efficiency is met.
Further, the first polishing machine and the second polishing machine each finish the polishing operation of the N/2 facet.
Specifically, the polishing time is longer, typically exceeding 1.5 times the grinding time. Therefore, in order to solve the problem of time bottleneck in the polishing process, the polishing process of the water drill facet is carried out in two machine positions, namely, the processing of one half of the water drill facet is completed through one polishing machine position, and the processing of the other half of the water drill facet is completed through two polishing machine positions, so that the purpose of balancing the processing time of the polishing machine position is achieved.
Further, a polishing material of a polishing machine position polishing wheel is set to have the outer diameter of D 3 and the inner diameter of D 2,D3＞D2＞D1;
n 2 is the wheel throwing speed.
In particular, another concept of the application is to further balance the processing time of the polishing machine by designing the diameter of the polishing wheel.
Furthermore, the application provides a high-efficiency automatic water drill processing device, which comprises the steps of adjusting the rotation speed of a polishing wheel according to the consumption i of polishing materials,
0≤i<D3-D2。
Specifically, the polishing wheel of the polishing wheel machine position is different from the polishing wheel of the polishing wheel machine position, the polishing wheel surface of the polishing wheel is prepared in a diamond fragment doping mode, loss is not generated basically, the polishing wheel is polished by a polishing material in order to enable the polishing effect to be better, loss can be generated along with the polishing time, the polishing wheel rotating speed is adjusted in order to enable the polishing contact area to meet the polishing requirement, so that the contact area of the water drill after the polishing material is worn is compensated, and the polishing quality of the water drill is improved.
Further, the method comprises the steps of,
Specifically, the polishing surface of the polishing wheel of a polishing machine position is also arranged at the shortest feeding position of the needle bar, so that the feeding distance of the needle bar is shortest, and the feeding time of the needle bar is shortened, but as the polishing material is continuously worn, the distance of the needle bar from the polishing surface is further and further increased, the feeding time of the needle bar is gradually increased, and the inner diameter of the polishing material is limited by the formula so that the processing time of the polishing machine position still meets the requirement of a preset reference beat.
Further, the number of machine positions required for the polishing process is related to the polishing time for completing all the facets N of the water drill;
When (when) And adding a three-polishing machine position.
Specifically, with the lifting of polished facets, such as 8 facets to 12 facets, 18 facets, 24 facets, etc., a new polishing machine can be added for the purpose of balancing polishing processing time.
Further, according to the preset reference beat, when the facet is lifted, the grinding machine position is increased.
In some embodiments, the polishing wheel rotation speed n 2 takes a value according to the polishing yield rate y 5 of the water drill, and y 5 is more than or equal to 50%.
Specifically, when the rotation speed of the polishing wheel is too high, the polishing yield of the water drill is affected, so that the rotation speed of the polishing wheel is adjusted according to the polishing yield of the water drill.

Detailed Description
The present application will be described in detail with reference to fig. 1 to 5.
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The application provides a high-efficiency automatic water drill processing device which at least has the advantages of high processing efficiency, sufficient yield, controllable yield and the like.
Referring to fig. 1, a schematic diagram of an automatic processing line for a water drill according to the prior art in fig. 1 is shown.
Specifically, the water drill processing production line usually adopts a double-line circulation processing structure so as to realize the purposes of full-automatic processing circulation and improving the field utilization rate. And the common structure of the double-line circulation is to separate the double production lines by symmetrical lines. That is, one production line starts from the viscose process to the end of the blanking process, and the other production line adopts the same layout from the viscose process to the end of the blanking process. Such two-wire circulation is basically a common structure in the industry, and reference is made to the structural layout of patent CN104551915B, which also integrates the gluing station in the turret machine (the patent refers to the rotating device). Although the double-line circulation structure adopts the transfer matching station to carry out circulation matching, the overall structure mode is basically similar, and the mechanical structure of the device provided by the application can be understood by referring to the station structure.
Referring to fig. 2, a schematic structural diagram of an automatic processing device for a high-efficiency water drill according to an embodiment of the present application is shown in fig. 2.
Specifically, the application discards the concept of integrating the turntable machine position and the adhesive working procedure in the prior art based on the analysis of the working procedure occupation processing time, but peels the adhesive working procedure from the turntable machine position, reduces the working time of the turntable machine position, integrates the flushing working procedure which does not occupy the working time in the turntable machine position, and achieves the purposes of not only adding the machine position, increasing the equipment cost, but also reasonably allocating the production beats.
The production line is not located at the turntable machine position like the prior art, but is located at the tail end of the other side operation line (see the guide of a dotted line, the two production lines are separated by the dotted line), and enters the turntable machine position through the matching station after sequentially passing through the viscose machine position and the feeding machine position. It will be appreciated that the cooperating stations do not operate the rows of pins at all, whereas the flushing station flushes the moving rows of pins only through the outlet of the continuous outlet water, both stations not occupying the working time of the turret machine. So the working time of the turntable machine position is improved. After the needle bar passes through the turntable machine position, the needle bar enters the starting end of the side operation line through rotation operation, and then sequentially passes through the coarse grinding machine position, the fine grinding machine position, the first polishing machine position, the second polishing machine position, the high-frequency heating machine position and the blanking machine position to finish single-line processing of the water drill in the high-efficiency water drill automatic processing device. And then the needle bar enters the viscose machine position of the other production line again, and the processing operation of the other line is started, so that double-line circulation is formed. The application separates and rearranges the working procedure and the machine position, so that each machine position is only required to be responsible for the operation of the machine position except the common needle row driving operation, thereby improving the working time of each machine position, reducing the production beat in the full-automatic production process of the water drill and improving the yield of the water drill.
Further, please refer to the following table 1, which is a comparison table of the takt time of the present application with the prior art.
Table 1 table of the present application against prior art working time
As can be seen from Table 1, compared with the water drill processing device provided by the prior art, the high-efficiency water drill automatic processing device provided by the application can effectively reduce the production takt 2.38s to 1.92s, namely, the production can be improved by 1.24 times by calculating the water drill automatic processing device in a unit of day.
Obviously, the high-efficiency automatic processing device for the water drill effectively balances the processing time of each machine position in the production process of a processing production line, reduces the overall production beat and greatly improves the yield of the water drill.
Furthermore, the application provides a double-line circulation processing structure, wherein any processing line sequentially comprises a viscose machine position, a feeding machine position, a turntable machine position, a coarse grinding machine position, a fine grinding machine position, a first polishing machine position, a second polishing machine position, a high-frequency heating machine position and a discharging machine position, and the discharging machine position of one processing line is connected with the viscose machine position of the other processing line to form double-line circulation.
Furthermore, the pin row driving is used as common transmission time, and the reduction of the driving time or the increase of the number of pin row clamping can improve the processing yield of the water drill. Therefore, the application moves the installed position of the rotary table machine position to the direction away from the rough grinding machine position, and extends the length of the needle row on the basis of the original size of the needle row so as to reach the maximum allowable length of the rough grinding machine position.
It should be noted that, due to the limitation of the product line structure of the water drill processing provided in the prior art, the needle row cannot be expanded to the maximum allowable length, which is typically 900mm. According to the application, the position of the turntable machine position is moved, so that the length of the needle row is extended to 950mm of the maximum allowable length under the condition that the driving time of the needle row is not influenced, and the yield of the water drill is increased to 1.06 times.
Referring to fig. 3, a cross-sectional schematic diagram of the viscose station (a), the feeding station (B) and the discharging station (C) according to the embodiment of fig. 3 is shown.
Specifically, the gluing procedure refers to spreading glue powder in the powder box, after the pin rows are transferred to the gluing machine through the driving mechanism, controlling the pin rows to feed to the powder box, and enabling the heated pin rows to contact the spread glue powder so as to enable the glue powder to be adhered to the pin rows. In fig. 3A, a schematic cross-sectional view of the glue station is shown, comprising a frame, a powder box leveling mechanism, a pin row driving mechanism, a pin row track. Wherein, the needle row track is shared by the operation line on one side, and the needle row is circulated on the needle row track. The powder box pushing mechanism is used for pushing and leveling the rubber powder in the powder box, and the powder box pushing mechanism and the powder box are arranged on the frame. The needle bar driving mechanism is arranged on the frame and used for driving the needle bar which flows to the viscose machine position to feed to the powder box, so that the powder feeding operation is completed.
The loading procedure is to hold the bead embryo to be loaded in the material box, control the matching mechanism below the material box to feed towards the needle bar after the needle bar is transferred to the loading machine position through the driving mechanism, and load the bead embryo to the needle bar through the matching of the matching mechanism and the needle bar. In fig. 3B a schematic cross-sectional view of the loading station is shown, comprising a frame, a magazine, a mating mechanism. Wherein, magazine, cooperation mechanism set up in the frame, and splendid attire is waited to process the pearl embryo in the magazine, and cooperation mechanism is provided with and needle bar block pearl embryo wants complex bayonet socket, and cooperation mechanism is through driving to needle bar direction feeding, accomplishes the material loading of pearl embryo.
The blanking procedure is to feed the bead embryo brush arranged at the blanking machine position to the needle row after the needle row flows to the blanking machine position through the driving mechanism, and brush the bead embryo on the needle row through the rotating bead embryo brush so as to enable the bead embryo to fall into the receiving box. Fig. 3C shows a schematic cross-sectional view of the blanking station. It comprises a frame, a receiving box and a bead embryo brush. The receiving box and the bead embryo brush are arranged on the frame, the bead embryo brush is driven to feed towards the needle row, and the bead embryo clamped by the needle row is brushed to fall off from the needle row and fall into the receiving box.
Because the flushing process and the high-frequency heating process are both performed on the moving needle bar, the water outlet or the heating port is only required to be aligned with the working part of the needle bar, and therefore the structure of the needle bar is not shown, and the structure can be understood by referring to other machine positions.
Referring to fig. 4, a schematic cross-sectional view of a rough grinding machine (D) and a polishing machine (E) according to the embodiment of the application is shown in fig. 4.
Specifically, the grinding process refers to feeding of the needle row to a rotary grinding wheel after the needle row flows to a rough grinding or fine grinding machine position through a driving mechanism, and integrally grinding a plurality of arranged bead blanks through the surface of the movable grinding wheel, and the polishing process refers to integrally polishing the plurality of arranged bead blanks through the surface of the movable polishing wheel after the needle row flows to a first polishing or second polishing machine position through the driving mechanism, and then feeding of the needle row to the rotary polishing wheel. Wherein D 1 is the diameter of the grinding wheel at the rough grinding machine position, D 2 is the inner diameter of a polishing sleeve at the polishing machine position, D 3 is the outer diameter of the polishing sleeve at the polishing machine position, and the polishing sleeve is sleeved with a roller in a sleeving manner.
Further, as can be seen from table 1, the working time of each machine position of the viscose, feeding, turntable flushing, rough grinding, fine grinding, one-shot, two-shot, heating and discharging is different without considering the common time of needle row driving. Because the rotation operation or the rotation operation of the turntable machine position in the flushing process of the turntable is limited by the rotation speed of the motor and the stability of the mechanism, the working time is basically determined, and the operations such as gluing, feeding, discharging and the like only need to control the feeding operation, and the working time is smaller than the turntable machine position, so that the turntable machine position can be used as a reference to determine the production beat. At this time, the coarse grinding machine position, the fine grinding machine position, the first polishing machine position and the second polishing machine position become bottleneck processes for restricting the production takt time, so that the production yield of the water drill cannot be further improved.
Further, the operation time of the turntable machine is taken as the beat reference of the processing line, and the reference beat R X＝SZ+SA is preset, so that the time Ry=S Z+y+ta≤RX of the rough grinding machine, namely the processing time y is less than or equal to R X-SZ-ta＝SA-ta, is ensured.
Further, the method comprises the steps of, pi x D 1*y*n1 = N x L, thenWhen D 1 is larger thanAnd when the final production time Ry of the coarse grinding machine position is less than or equal to R X, the bottleneck problem of the coarse grinding machine position is solved, the final production time is less than the time spent by the rotary table machine position, and the production takt of the device provided by the application is smaller, and the water drill yield is higher.
N is the number of facets of the water drill, L is the processing length of any facet of the water drill, N 1 is the rotation speed of the grinding wheel, t a is the minimum feeding time allowed by the needle bar, R X is the reference beat, S Z is the shortest time for driving the needle bar to move from one machine position to the next machine position, and S A is the time required by the turntable machine position to finish one rotation operation/revolution operation.
Specifically, the grinding efficiency of the blank is mainly related to the diameter of the grinding wheel and the rotation speed of the grinding wheel, and the rotation speed of the grinding wheel affects the grinding quality of the blank. Thus, the present application treats the wheel speed as a constant, and reduces the working time of grinding by increasing the diameter of the wheel, as shown in Table 2.
Table 2 grinding wheel diameter and working time table
| Diameter/mm of grinding wheel | 300 | 310 | 320 | 330 | 340 | 350 | 360 | 370 | 380 | 390 | 400 |
| Operating time/s | 1.253 | 1.232 | 1.214 | 1.195 | 1.173 | 1.152 | 1.134 | 1.113 | 1.092 | 1.075 | 1.055 |
As can be seen from table 2, the working time of the grinding wheel machine decreases with increasing diameter of the grinding wheel.
In theory, when the diameter of the grinding wheel at the rough grinding machine position is between 370 and 400mm, the working time of the grinding wheel can be matched with the working time of the rotary table machine position, so that the optimal production takt time is 1.76s.
It is worth noting that the larger the diameter of the grinding wheel is not, the better, and while the larger the diameter of the grinding wheel will provide less working time, the larger the required installation space of the frame will be, increasing the manufacturing cost of the mechanism. Therefore, the diameter of the grinding wheel is properly increased, the working time reduction provided by the diameter of the grinding wheel can be aligned with the preset reference beat, and the diameter of the grinding wheel can be controlled within the receivable range of the frame.
Referring to fig. 5, fig. 5 is a schematic diagram showing the adjustment of the actual reference beats according to the embodiment of the present application.
Specifically, the application comprises the following steps:
The method comprises the steps that S1, feeding speeds of all machine positions are preset according to preset reference beat R X, so that feeding time of a viscose machine position, a feeding machine position, a coarse grinding machine position, a fine grinding machine position, a first polishing machine position, a second polishing machine position and a discharging machine position is S 1、S2、S3、S4、S5、S6、S7 respectively;
Then, the actual processing time and the actual yield of each machine position are acquired in real time by utilizing the step S2, wherein the actual processing time and the actual yield are respectively S 1′、S2′、S3′、S4′、S5′、S6′、S7′ and y 1、y2、y3、y4、y5、y6、y7;
then, through step S3, the ratio of the reciprocal of the actual yield is used as the adjustment weight to obtain the actual reference beat R X′,
Finally, through step S4, the feeding speed of each machine position is adjusted in real time according to the actual reference beat R X′.
Furthermore, the actual operation of the high-efficiency water drill automatic processing device provided by the application can effectively improve the processing yield of the water drill by taking the operation time of the turntable machine as a preset reference beat. However, in actual operation, the actual processing time of each machine is often different due to the error of the driving mechanism. Meanwhile, the retention of the working time of the machine position influences the yield of the machine position water drill.
Therefore, the preset reference beats are adjusted by measuring and calculating the actual processing time through the condition of the yield of the water drill at each machine position as the adjustment proportion, so that the yield of the water drill and the yield of the water drill are balanced, the yield of the water drill is improved, and the yield of the water drill is ensured.
Furthermore, the actual yield of each machine position in the production and processing process of the water drill can be obtained by continuously shooting and comparing images in the production process of the water drill through the high-frequency camera, and each actual processing time can be obtained through the sensor.
Further, the first polishing machine and the second polishing machine each finish the polishing operation of the N/2 facet.
Further, a polishing material of a polishing machine position polishing wheel is set to have the outer diameter of D 3 and the inner diameter of D 2,D3＞D2＞D1;
n 2 is the wheel throwing speed.
Specifically, the sizes of the polishing wheel diameters of the first polishing machine position and the second polishing machine position also influence the polishing operation time.
Please refer to the following table 3, which shows the relationship between the diameter of the polishing wheel and the working time.
TABLE 3 polishing wheel diameter and working time Table
| Outer diameter D3/mm | 330 | 340 | 350 | 360 | 370 | 380 | 390 | 400 | 410 | 420 | 430 |
| Operating time/s | 1.103 | 1.096 | 1.092 | 1.087 | 1.081 | 1.075 | 1.069 | 1.065 | 1.061 | 1.055 | 1.049 |
Furthermore, the application provides a high-efficiency automatic water drill processing device, which comprises the steps of adjusting the rotation speed of a polishing wheel according to the consumption i of polishing materials,
0≤i<D3-D2。
Specifically, after the polishing materials are worn, the feeding time of the needle bar is continuously increased, and the rotation speed of the polishing wheel is properly regulated to make the rotation speed of the polishing wheel faster in order to compensate the working time of the polishing machine position.
Further, the number of machine positions required for the polishing process is related to the polishing time for completing all the facets N of the water drill;
When (when) And adding a three-polishing machine position.
