Detailed Description
The invention is further described below with reference to the drawings and examples.
As shown in fig. 1-3, the present embodiment provides a portable three-dimensional manual pipe bender, which comprises a housing 1, a pipe bending mechanism 2, a folding guide mechanism 3 and a clamping mechanism 4. The shell 1 is composed of a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 can be relatively folded to form the shell 1 with a box-type structure. Two ends of the folding guide rail mechanism 3 are respectively connected with two shells, the folding guide rail mechanism 3 is unfolded when the two shells are separated, and the folding guide rail mechanism 3 is folded in the shell 1 when the two shells are folded. Solves the problem that the existing three-dimensional manual pipe bending machine cannot reduce the volume due to the limitation of the track length.
The clamping mechanism 4 is slidably arranged along the folding guide rail mechanism 3, and when the folding guide rail mechanism 3 is folded and folded in the shell 1, the clamping mechanism 4 can be disassembled, so that the thickness of the folding guide rail mechanism 3 in a folded state is reduced, and the size of the shell 1 is further reduced. The detached clamping mechanism 4 can be independently placed in the spare space in the housing 1. The pipe bending mechanism 2 is arranged on the first shell 11 and aligned with the folding guide rail mechanism 3, and the axis of the pipe bending station of the pipe bending mechanism 2 is overlapped with the axis of the pipe clamped by the clamping mechanism 4 through position correction adjustment, so that the three-dimensional pipe bending process can be correctly executed after the three-dimensional manual pipe bending machine is fed.
In order to facilitate the bending operation, a working plane is provided on the top surface of the housing 1. Based on this, the pipe bending mechanism 2 is located on the top surface of the first housing 11 in the working state, and the corresponding folding guide rail mechanism 3 needs to be lifted to the top end of the housing 1 in the working state, so as to keep the height of the pipe bending mechanism 2 level. The folding guide rail mechanism 3 needs to be lowered in height in consideration of the folding state when the folding guide rail mechanism 3 is folded, so that the folding guide rail mechanism 3 which is raised by folding is prevented from exceeding the top of the housing 1.
In summary, in one embodiment, a structure for adjusting the height of the folding guide rail mechanism 3 is provided. The height-adjusting structure comprises: two first screws 111 vertically disposed in the first housing 11 and two second screws 121 vertically disposed in the second housing 12. Through holes are respectively formed at two ends of the folding guide rail mechanism 3, so that the two ends of the folding guide rail mechanism 3 slide along the two first screw rods 111 and the two second screw rods 121 respectively. And positioning nuts are matched on the four screws simultaneously and used for locking the position of the folding guide rail mechanism 3 after the height adjustment is finished. Therefore, the folding guide rail mechanism 3 can be lifted to the height of the working plane in the working state, the locking of the positioning nut is released after the working is finished, the folding guide rail mechanism 3 is lowered and folded, and the folding guide rail mechanism 3 in the folded state is fully accommodated in the shell 1. The folding guide rail mechanism 3 can be protected from being damaged in the transportation and dragging process, and the clamping and injuring of technicians can be prevented. And the flat shell 1 is also convenient for arranging and transporting space, so that the carrying amount of tools or materials when technicians go out of the field is increased, and the working efficiency is improved.
The folding guide mechanism 3 includes a first guide rail 31, a second guide rail 32, a first slider 33, and a second slider 34. The first sliding block 33 is slidably disposed on the first screw 111, the second sliding block 34 is slidably disposed on the second screw 121, and the two sliding blocks are respectively used as sliding carriers at two ends of the folding guide rail mechanism 3. The first guide rail 31 and the second guide rail 32 are arranged between the two sliding blocks, wherein one end of the first guide rail 31 is hinged with one end of the second guide rail 32, so that the two guide rails can be turned and overlapped by taking the hinged position as a central shaft. The other end of the first guide rail 31 is hinged with the first sliding block 33, and the other end of the second guide rail 32 is hinged with the second sliding block 34, so that the two guide rails are not limited by the two sliding blocks when being folded. The folding guide rail mechanism 3 of the embodiment can not only longitudinally adjust the height along four screws, but also has the folding effect in the horizontal direction.
Based on the above embodiment, the folding manner of the folding guide mechanism 3 includes at least two of the following:
the first folding mode is that the two sliding blocks slide along the four screw rods in advance to lower the folding guide rail mechanism 3 to the bottom of the shell 1, and then the hinged position of the two guide rails is lifted upwards, so that the two guide rails are folded in a reverse V shape. The folding structure has the advantages that after the two sliding blocks are locked through the positioning nuts, the two guide rails can only be turned upwards without the degree of freedom of turning downwards, so that the two guide rails can be kept in a horizontally unfolded state without additional support or limiting structures.
The second middle folding mode is that the hinged positions of the two guide rails are pressed downwards without adjusting the height of the two sliding blocks, so that the two guide rails are folded in a V shape. The folding structure has the advantages that the step of adjusting the height through the two sliding blocks is omitted, and the efficiency of folding the folding guide rail mechanism 3 is improved. However, due to the folding mode, the two guide rails have the degree of freedom of downward overturning, and under the influence of gravity, when the two guide rails are horizontally unfolded, an additional supporting or limiting structure is needed to be assisted to keep the use state of the two guide rails.
In the above embodiment, the problem of how to fold the folding guide mechanism 3 inside the housing 1 is solved, but as an important component of the three-dimensional manual pipe bender, the pipe bending mechanism 2 needs to have the effect of being accommodated inside the housing 1. Thus, in one embodiment, the pipe bending mechanism 2 includes a flipping plate 21, a flipping shaft 22, a die wheel assembly 23, and a film pressing assembly. Wherein the die wheel assembly 23 and the die assembly 24 are two actuating structures for actuating the planar elbow, both of which are mounted on the roll-over plate 21 as a carrier. The inversion plate 21 is mounted on the top end of the first housing 11 through an inversion shaft 22, and the inversion plate 21 carries these two components and can rotate around the inversion shaft 22.
When the turnover plate 21 rotates to a state of being horizontally carried on the top surface of the first shell 11, the two components are located on the top surface of the turnover plate 21 at the moment, and after the two components are aligned with the folding guide rail mechanism 3, the clamping mechanism 4 is installed, so that the pipe bending operation can be performed.
When the roll-over plate 21 is turned to be suspended inside the first housing 11, both components are located in the space inside the first housing 11. The folding guide rail mechanism 3 is folded and the two shells are folded, so that the effect of accommodating the pipe bending mechanism 2 in the shell 1 is realized.
It should be noted that the top of the first housing 11 is provided with an opening allowing the flipping plate 21 to perform a flipping action.
In order to reduce the volume of the housing 1 in the closed state, it is necessary to reasonably allocate the space inside the housing 1. Therefore, if the folding guide mechanism 3 and the pipe bending mechanism 2 are kept in the axially aligned state all the time, the internal space of the housing 1 is crowded, and the pipe bending mechanism 2 cannot be turned over due to insufficient space. Thus, in one embodiment, the width of the housing 1 is increased, so that the pipe bending mechanism 2 and the folding guide mechanism 3 are respectively located at two sides of the center line of the first shell 11, and the respective folding or overturning operations of the two mechanisms are not affected.
In order to ensure realignment of the two mechanisms in the operating state, the inversion plate 21 is made slidable in the axial direction of the inversion shaft 22 in the present embodiment. Namely, when the pipe bending mechanism 2 turns over, the pipe bending mechanism 2 and the folding guide rail mechanism 3 are respectively positioned at two sides of the central line of the shell 1, and are not mutually interfered. After the pipe bending mechanism 2 rotates to the working state, the overturning plate 21 is pushed to slide along the overturning shaft 22, so that the pipe bending mechanism 2 translates to the other side of the central line of the shell 1 in the horizontal plane and is aligned with the folding guide rail mechanism 3.
Further, in order to simplify the alignment operation of the pipe bending mechanism 2 and the folding guide mechanism 3 and improve the alignment accuracy of the two mechanisms, in one embodiment, a limiting groove 112 is formed on the top surface of the first housing 11, and a limiting plate 211 is vertically disposed on the turning plate 21. When the pipe bending mechanism 2 is in an operating state, the overturning plate 21 is horizontally carried on the top surface of the first shell 11, and the limiting plate 211 is positioned in the first shell 11. The limiting plate 211 is inserted into the limiting groove 112 by the movement effect of the tilting plate 21 sliding along the tilting shaft 22. Through the cooperation of limiting plate 211 and spacing groove 112, realize the accurate location to bend pipe mechanism 2. And the cooperation of limiting plate 211 and spacing groove 112 can also promote the stability of return bend mechanism 2 when operating condition, avoids return bend mechanism 2 unexpected slip or rocking in the in-process of carrying out the return bend operation.
The specific structure of the die wheel assembly 23 comprises a fixed seat 231 and a die wheel 232, wherein the fixed seat 231 is arranged on the top surface of the turnover plate 21 when the pipe bending mechanism 2 is in a working state, and the die wheel 232 is axially connected to the top surface of the fixed seat 231, so that the die wheel 232 can generate autorotation under the condition of no movement of the axis. An arc groove is formed on the circumferential surface of the model wheel 232 and is used for limiting the pipe, so that the pipe is prevented from sliding in the pipe bending process.
The specific structure of the die assembly 24 includes a slide base 241, an adjustment rail 242, a die block 243, and a drive rod 244. The turnover plate 21 is provided with a circular arc chute 212, and the circle center of the arc chute 212 coincides with the circle center of the model wheel 232. The sliding seat 241 is disposed in the sliding groove 212, so that the sliding seat 241 can slide along the sliding groove 212 around the mold wheel 232. The adjusting rail 242 is mounted on the top surface of the sliding seat 241 along the radial direction of the mold wheel 232, and the pressing module 243 is slidably disposed on the adjusting rail 242 to adjust the distance between the pressing module 243 and the mold wheel 232. One end of the driving rod 244 is fixedly connected with the pressing module 243. The pressing module 243 is matched with the model wheel 232, and the pressing module 243 and the model wheel are respectively clasped on two sides of the pipe. By moving the driving rod 244, the sliding seat 241 is driven to slide along the sliding groove 212, so that the pressing module 243 rotates around the model wheel 232 along with the sliding seat 241, and the pipe between the pressing module and the sliding seat is bent.
It should be noted that the driving rod 244 adopts the lever principle, the driving rod 244 is used as a power arm, the pressing module 243 is used as a fulcrum, and the contact part of the pipe and the pressing module 243 is used as a resistance arm. The power arm is prolonged by the driving rod 244, so that the physical power consumed by the pipe bending operation is saved.
The clamping mechanism 4 of the three-dimensional manual pipe bending machine comprises a sliding sleeve 41, a rotary clamp 42 and a rotary rod 43. The sliding sleeve 41 is a hollow cylinder structure, and the outer wall of the cylinder structure is also provided with a sliding limiting structure capable of sliding along the folding guide rail mechanism 3. The sliding sleeve 41 can slide into the guide rail groove from one end of the folding guide rail mechanism 3 after the folding guide rail mechanism 3 is unfolded, so that the function of convenient disassembly is realized. The rotating clamp 42 is lined in the sliding sleeve 41, and the rotating clamp 42 can generate a rotating effect relative to the sliding sleeve 41. The rotating lever 43 is connected to the rotating jig 42 through the sliding sleeve 41. The rotary clamp 42 is used to clamp the end of the pipe, and the rotation direction and rotation angle of the rotary clamp 42, that is, the rotation direction and rotation angle of the pipe can be controlled by operating the rotation lever 43. And the feeding action of pipe processing is realized by the sliding effect of the sliding sleeve 41 along the folding guide rail mechanism 3, so that all functions of the three-dimensional manual pipe bending machine are realized.
To further enhance the protection effect of the housing 1 on the respective mechanisms, in an embodiment, the top of the housing 1 is further provided with a protective cover 14. When the folding guide rail mechanism 3 is folded, the two shells are folded to form the complete shell 1, the pipe bending mechanism 2 is turned over and stored in the shell 1, and then the protective cover 14 is buckled at the top end of the shell 1, so that the sealing effect of the shell 1 can be realized. Dust or sundries are prevented from falling into the shell 1 in the transportation process.
In order to increase the stability of the three-dimensional manual pipe bender in the working state, a weight can be placed on the bottom plate of the second shell 12, and the weight of the second shell 12 at the far end increases the resistance of the lifting lever according to the lever principle, so that the pipe bending operation at the top end of the first shell 11 can not cause the whole three-dimensional manual pipe bender to rotate.
For convenience of transportation, in one embodiment, six universal wheels 13 are further arranged at the bottom of the shell 1 of the three-dimensional manual pipe bending machine. So that the utility model can be pushed on the flat ground in the folding state, and can also be towed like a luggage case.
