Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bending machines, in particular to an automatic bending machine for processing copper parts of circuit breakers. Background Art
[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressing plate. The base is connected to the clamping plate through a hinge. The base is composed of a housing, a coil and a cover plate. The coil is placed in the recess of the housing, and the cover plate covers the top of the recess. When in use, an electric current is applied to the coil through a wire. After the current is applied, an attractive force is generated on the pressing plate, so as to realize the clamping of the thin plate between the pressing plate and the base.
[0003] When processing copper parts of circuit breakers, it is necessary to bend the copper parts into the required shape, so a bending machine is needed. When the traditional bending machine bends copper parts, the bending position falls into the bending groove. At this time, both ends of the copper parts will be worn due to friction with the structure, resulting in surface wear of the copper parts. In order to ensure the bending accuracy, marking lines are often drawn on the surface of the copper parts. When bending a large number of copper parts, if the marking lines are wiped off, the bending position will deviate, and at the same time, the bending efficiency will also be reduced.
[0004] Based on this, an automatic bending machine for processing copper parts of circuit breakers is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide an automatic bending machine for processing copper parts of circuit breakers in order to solve the above problems.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] An automatic bending machine for processing copper parts of circuit breakers includes an operating table, a support frame is connected to the operating table, a press is connected to the upper end of the support frame, a bending hand is connected to the lower end of the press, a V-shaped groove is opened on the operating table, a draw plate is slidably connected to the operating table, a limiting plate is connected to one end of the draw plate, and a positioning mechanism for structurally positioning the copper parts of the circuit breaker before bending is connected to the operating table.
[0008] Preferably, scales are opened on the draw plate, a pointer is connected to the operating table, and a handle groove is opened on the draw plate.
[0009] Preferably, a connecting ear is connected to the operating table, a telescopic rod is slidably connected to the connecting ear, an extrusion block is connected to one end of the telescopic rod, and an extrusion spring is connected between the extrusion block and the connecting ear.
[0010] Preferably, the positioning mechanism includes a positioning block. Side blocks are connected to the workbench, and a rotating seat is rotatably connected between the side blocks. The positioning block is slidably connected to the rotating seat.
[0011] Preferably, a chute is formed on the rotating seat, and the positioning block is slidably connected to the chute.
[0012] Preferably, a sliding rod is connected to one side of the positioning block. One end of the sliding rod is connected to a traction bar, and a pair of symmetrical springs are sleeved on the sliding rod.
[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:
[0014] 1. By adopting the limiting plate structure in this application, since the limiting plate is movable, one end of the copper part can be abutted against the limiting plate before bending the copper part, so as to complete the limitation of the bending position of the copper part. After the limiting plate moves, the number pointed by the pointer to the scale will change, and the position of the draw plate can be fixed by the extrusion block, ensuring that the bending positions of copper parts in the same batch are unified.
[0015] 2. By adopting the positioning block structure in this application, the copper part placed on the workbench is always in the middle position by using the positioning block, ensuring that the bending hand can accurately complete the bending of the copper part when it falls, and the V-groove structure on the workbench can well protect the bending structure, avoiding the copper part from popping out during bending and causing safety accidents.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution:
[0023] An automatic bending machine for processing copper parts of a circuit breaker includes an operating table 1. A support frame 2 is connected to the operating table 1. A press 3 is connected to the upper end of the support frame 2. The support frame 2 is used to ensure the stability of the connection of the press 3. A bending hand 18 is connected to the lower end of the press 3. A V-shaped groove 4 is formed on the operating table 1. The copper part is squeezed by the bending hand 18 to make the structure bend into the angle of the V-shaped groove 4. A draw plate 5 is slidably connected to the operating table 1. A limiting plate 10 is connected to one end of the draw plate 5. The limiting plate 10 and the draw plate 5 are perpendicular to each other. A positioning mechanism for positioning the structure of the circuit breaker copper part before bending is connected to the operating table 1.
[0024] Specifically, as Figure 1 shown, a scale 16 is formed on the draw plate 5. A pointer 15 is connected to the operating table 1. A handle groove 17 is formed on the draw plate 5. The pointer 15 structure points to one side of the scale 16. By pulling the draw plate 5, the vertical position of the pointer 15 pointing to the scale 16 can be changed.
[0025] Specifically, as Figure 1 shown, a connecting ear 6 is connected to the operating table 1. A telescopic rod 7 is slidably connected to the connecting ear 6. An extrusion block 8 is connected to one end of the telescopic rod 7. An extrusion spring 9 is connected between the extrusion block 8 and the connecting ear 6. By setting the extrusion block 8, the draw plate 5 can be positioned, but under strong external forces, the draw plate 5 can still move.
[0026] Specifically, as Figure 1 and Figure 3 shown, the positioning mechanism includes a positioning block 19. Side blocks 11 are connected to the operating table 1. A rotating seat 12 is rotatably connected between the side blocks 11. The positioning block 19 is slidably connected to the rotating seat 12. By setting the rotating seat 12, when the copper part is bent, the rotating seat 12 can rotate synchronously, reducing wear between structures and improving the bending quality of the copper part.
[0027] Specifically, as Figure 3 shown, a chute 21 is formed on the rotating seat 12. The positioning block 19 is slidably connected to the chute 21. By setting the chute 21, the sliding of the positioning block 19 is more stable.
[0028] Specifically, asFigure 3 As shown, a slide bar 13 is connected to one side of the positioning block 19. One end of the slide bar 13 is connected to a traction bar 14. Symmetric springs 20 are sleeved on the slide bar 13. By setting the slide bar 13 and the traction bar 14, the sliding of the positioning block 19 is stable, and the symmetric springs 20 have the same structure, ensuring that the copper part is in the middle position of the workbench 1 during positioning. The traction bar 14 is a structure similar to a belt, and its structure can be bent at will to ensure that the slide bar 13 can rotate.
[0029] In summary, for an automatic bending machine for processing breaker copper parts provided in this embodiment, when it is necessary to bend the breaker copper parts, control the sliding of the draw plate 5 on the workbench 1 so that the pointer 15 indicates the corresponding scale 16. At this time, the extrusion block 8 completes the positioning of the draw plate 5. Pull the traction bar 14, place the copper part on the rotating seat 12, ensure that one end of the copper part abuts against the limiting plate 10, and the abutting force should not be too large. Release the traction bar 14. At this time, both sides of the copper part move to directly below the bending hand 18 under the clamping action of the positioning block 19. Operate the press 3 to drive the bending hand 18 to press down the copper part, so that the copper part completes the bending operation.
[0030] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
