Description

A device for punching holes on the inner wall of a metal roller

Technical Field

The present application relates to the technical field of punching, and in particular to a device for punching holes on the inner wall of a metal roller.

Background Art

Rollers are cylindrical parts, divided into driving and driven rollers, used in various transmission and conveying systems such as printing machines, digital printers and other conveying equipment, papermaking and packaging machinery, etc. They are mostly made of stainless steel, cast steel, and solid forged alloy steel core.

When connecting small hollow rollers, welding can be used, while large hollow rollers are connected by punching holes in the inner wall, and then a connecting device is installed in the hole in the inner wall to fix the two rollers. The existing device allows the iron filings generated after processing to remain in the device, and then cleans the iron filings after the entire processing operation is completed. The cleaning method mainly adopts the continuous recovery and filtration treatment of the cutting fluid. Since the equipment is constantly operating, the cutting fluid mixed with iron filings enters the recovery device through a fixed pipeline for filtration and collection. Since the rollers are usually large in size, the iron filings generated by punching are also large, resulting in a greater demand for recycling space. If a simple method of increasing the recycling space is adopted, when processing large rollers, the space requirements for the processing site are very high, and a large amount of iron filings are stored in the recovery device for a long time, which is easy to cause clogging of the filter device, affecting the filtering effect, and also increasing the loss and cost of the filter device. On the other hand, if the method of regularly cleaning the recovery device is adopted, the staff needs to shut down the equipment and clean the iron filings before processing again, which greatly increases the overall working time of drilling and the labor of the staff.

Therefore, it is necessary to provide a metal roller inner wall punching device to solve the above problems.

Embodiment 1: Method for using the metal roller inner wall punching device

Step 1: Place the support assembly 1 into the inner wall of the metal roller

Specifically, as shown in Figure 13, after the staff places the metal roller using a floor stand (not shown in the figure), they use a lifting device to connect to the mounting parts of the first support block 6 and the second support block 61, and lift the support assembly 1 to one side of the inner wall of the metal roller. After the recovery assembly 3 falls to the ground, the height of the stand is adjusted to make the metal roller flush with the support assembly 1 to ensure that the support assembly 1 can enter the inner wall of the metal roller. The recovery assembly 3 is against the outer wall of one side of the metal roller, and the support assembly 1 slides on the recovery assembly 3. The depth of entry of the support assembly 1 is judged by the scale line. The punching process is carried out from the innermost part of the metal roller to the outside in sequence. When the operating depth is reached, the telescopic cylinders on the first support block 6 and the second support block 61 are started. When the top support member 4 and the bottom support member 5 are against the inner wall of the metal roller, the telescopic cylinders are stopped.

Step 2: Start punching component 2 to punch the workpiece

Specifically, the angle drill 10 is started through the control center, and the angle drill 10 drives the drill bit 11 to rotate, as shown in Figure 13, and the nozzle 25 is adjusted to the front of the drill bit 11, toward the recovery component 3, and the first double-axis cylinder 7 and the second double-axis cylinder 71 are controlled to extend through the control center, and the first double-axis cylinder 7 and the second double-axis cylinder 71 drive the first fixed plate 8 and the second fixed plate 81 to extend, and drive the connecting plate 9 to descend, so that the angle drill 10 descends, and the drill bit 11 enters the through groove 51 to punch the metal roller.

Step 3: Start the suction pump 17 to cool the processing environment and recover the iron chips and coolant.

Specifically, as shown in FIG. 14 , the angle of the nozzle 25 is adjusted, and the nozzle 25 is aligned with the drill bit 11 and the direction of the recovery component 3. The suction pump 17 is turned on through the control center. The suction pump 17 draws the coolant from the bottom of the shell 14 into the coolant pipe 24. The coolant is sprayed out from the nozzle 25 to cool the drill bit 11. Since the coolant sprayed from the nozzle 25 is directed toward the recovery component 3, the iron filings and the coolant are impacted by the liquid and flow along the inner wall of the bottom of the metal roller, from the arc-shaped opening 141 into the recovery component 3, and then flow along the arc surface of the boss 142 into the filter cartridge 21. The filter cartridge 21 separates the iron filings and the coolant, and the iron filings remain in the filter cartridge 21. The coolant is filtered out from the filter cartridge 21 and falls to the bottom of the shell 14.

It should be noted that when the drilling is completed, a small amount of coolant will flow down the hole. A container can be placed under the drilling point. Since this problem is not closely related to the problem to be solved by the present invention, it will not be elaborated on here.

Step 4: When adjusting the drilling position, the iron chips are compressed by the pressure plate 185

Specifically, when the hole is drilled, the control center starts to shorten the first double-axis cylinder 7 and the second double-axis cylinder 71, and shortens the first support block 6 and the second support block 61 at the same time. The support assembly 1 is moved toward the outer side of the metal roller through the mounting parts on the first support block 6 and the second support block 61, driving the bottom support member 5 to slide. At this time, the rack 52 is engaged with the gear 1831, and the gear 1831 rotates clockwise, driving the roller 1832 to rotate, and the contact column 1823 slides in the slide groove 1833. When the contact column 1823 is in the arc portion 18331, as shown in FIG. 15, the compression block 1822 follows the rotation of the roller 1832 and descends, and the connecting column 1825 drives the compression The plate 185 descends, and the clamping spring 1824 is compressed with elastic force. The pressure plate 185 enters the filter cartridge 21 from the opening 201 to squeeze the iron filings in the filter cartridge 21. When the contact column 1823 is in the vertical portion 18332, the clamping spring 1824 releases the elastic force, and the compression block 1822 rises under the action of the elastic force. The connecting column 1825 drives the pressure plate 185 to rise, and the pressure plate 185 pops out of the filter cartridge 21. The gear 1831 continues to roll, driving the pressure plate 185 to move up and down, squeezing the iron filings in the filter cartridge 21 back and forth, thereby reducing the gap between the iron filings and accommodating more iron filings. At the same time, the iron filings are collected together, making it convenient for the staff to clean the device.

Step 5: Start the motor 16 to accelerate the cooling of the coolant

Specifically, after the motor 16 is started by the control center, the power is transmitted to the gear box 15, and the rotating shaft 22 rotates under the output of the gear box 15, driving the guide plate 23 to rotate. The guide plate 23 stirs the coolant, so that the high-temperature coolant passing through the workpiece is quickly merged with the low-temperature coolant in the shell 14. While stirring, the contact area between the coolant and the air is increased, and the cooling speed of the coolant is accelerated. At the same time, the filter cartridge 21 also rotates to throw out the coolant remaining on the iron filings in the filter cartridge 21.

It should be noted that when the support assembly 1 moves to the innermost part of the metal roller, the roller 1832 rotates counterclockwise. Due to the setting of the arc-shaped portion 18331, the roller 1832 can only drive the compression block 1822 to press down when it rotates clockwise. Therefore, the counterclockwise rotation of the roller 1832 will cause the entire device to get stuck. At this time, it is necessary to control the telescopic device on the compression block 1822, as shown in Figure 16, to retract the contact column 1823. Under the influence of the elastic force of the compression spring 1824, the contact column 1823 is flush with the annular groove 1835, and the contact column 1823 is controlled to extend into the annular groove 1835. At this moment, the contact column 1823 slides in the annular groove 1835 to avoid getting stuck. When it is found that the support assembly 1 cannot be pulled outward, it means that the iron filings in the filter cartridge 21 have been pressed to the maximum amount, and the staff is required to clean the iron filings in the filter cartridge 21. The iron filings will not only fall into the filter cartridge 21, but also fall onto the filter screen 20.

In summary, the device can increase the amount of iron filings collected and separate the coolant and iron filings by providing a filter screen 20 and a filter cartridge 21. By providing a pressing component 18, the iron filings in the filter cartridge 21 can be compressed, reducing the gaps between the iron filings, and pressing the iron filings together for easy recycling by staff, thus solving the current technical problem of long-term accumulation of iron filings and difficulty in cleaning and recycling.

The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
