Description

Technical Field

[0001] The utility model relates to the technical field of copper busbar bending, in particular to a positioning tool for a bending machine. Background Art

[0002] Early power transmission relied primarily on low-voltage direct current (DC) transmission technology. However, due to limitations in transmission distance and efficiency, AC transmission technology gradually shifted to the latter. AC transmission technology uses transformers to adjust voltage levels to meet transmission needs over varying distances. With the growth of power demand and the expansion of power grids, high-voltage power transmission technology emerged. High-voltage transmission technology reduces transmission current by increasing the transmission voltage, thereby reducing transmission losses and line costs. Currently, ultra-high voltage transmission technology has become a crucial means of long-distance, high-capacity power transmission.

[0003] In power transmission, copper busbars play an extremely critical role. As a high-quality conductive material, copper busbars have extremely low resistivity, which enables them to effectively transmit large currents. They not only ensure stable current transmission, but also significantly reduce energy loss and improve power transmission efficiency. However, when copper busbars are used for transmission and connection, many areas require bending of the copper busbars. However, how to bend the copper busbars accurately and without damage has become a major challenge.

[0004] The utility model with application number CN202321447559.X is a positioning tool for a bending machine, comprising a bending table, a bending mechanism installed at the upper end of the bending table, a support platform installed at the front end of the bending table, a rotating table rotatably connected to the center of the upper end of the support platform, a clamping and positioning mechanism installed on the rotating table, an angle scale provided at the upper end of the support platform, a pointer pointing to the angle scale provided on the rotating table, and a plurality of butterfly bolts threadedly connected to the support platform for positioning the rotating table. The advantages of this utility model are: the thin plate is clamped and positioned by the clamping and positioning mechanism to prevent the thin plate from deflecting during bending, thereby ensuring the bending quality of the thin plate, and the position of the roller two is changed by a motor drive according to the width of the thin plate, which has high applicability and reduces the labor intensity; through the cooperation of the angle scale and the pointer, the rotating table rotates on the support platform, and the position of the rotating table is fixed by butterfly bolts, so that the device can perform angled tilt bending on the thin plate, and has high versatility.

[0005] This application clamps the thin plate through a clamping and positioning mechanism to prevent the thin plate from tilting, but when bending the copper busbar, the bending part of the copper busbar needs to be accurately positioned. At the same time, the bending force needs to be prevented from being too strong, which may cause cracks on the bending part of the copper busbar surface, resulting in inability to function in power transmission and increasing the cost of use.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of the utility model is to provide a positioning tool for a bending machine which can effectively solve the above technical problems.

[0008] In order to achieve the purpose of this utility model, the following technical solutions are adopted:

[0009] A positioning tool for a bending machine, comprising: a clamping assembly for clamping a copper busbar, a bending assembly for bending the copper busbar, and a cooling assembly for blowing air onto the bent copper busbar;

[0010] The engaging assembly includes a mounting frame, a moving block, a positioning rod, and a limiting wheel; the mounting frame is slidably connected to the moving block, the moving block is threadedly connected to the positioning rod, and the limiting wheel is fixedly connected to the mounting frame;

[0011] The moving block is provided with a plurality of groups of holes, and the moving block is symmetrically arranged in two groups along the long side direction of the mounting frame.

[0012] Furthermore, the bending assembly consists of a press, a fixed shell, a limiter, and a clamping member; the press is slidingly connected to the fixed shell, the fixed shell is rotatably connected to the limiter, and the clamping member is fixedly connected to the fixed shell.

[0013] Furthermore, the cooling assembly includes an air pump, a conductive shell, an air bag, and an air pipe; the air pump is connected to the conductive shell, the conductive shell is connected to the air bag, and the conductive shell is connected to the air pipe.

[0014] Furthermore, a cylinder is installed next to the cooling assembly, and one corner of a triangular plate is hinged to the output end of the cylinder, and the other two corners of the triangular plate are hinged to the fixing plate and the connecting piece respectively.

[0015] Furthermore, the connecting member is fixedly connected to the mounting frame.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a positioning tool for a bending machine. When the cylinder drives the mounting plate to rise and fall, the copper busbar is placed on the positioning rod and the positioning rod is rotated at the same time to make the two sets of moving blocks move relative to each other, thereby clamping the side edges of the copper busbar to prevent it from shifting during bending. When the copper busbar needs to be bent to different angles, the positioning rod is inserted into different holes to change the position of the copper busbar and the distance between the press fitter, so that the bending angle of the copper busbar can be adjusted when it is bent. By adjusting the position of the positioning rod, copper buses at different angles can be bent, which is convenient for power transmission and layout. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments.

[0026] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 5 As shown, a positioning tool for a bending machine includes: a clamping component 5 for clamping the copper busbar, a bending component 6 for bending the copper busbar, and a cooling component 7 for blowing air on the bent copper busbar.

[0028] As we all know, when a copper busbar is bent, its surface will be subjected to shear force, which may easily cause its surface to crack or, during the bending process, improper positioning of the copper busbar may cause the bending position of the copper busbar to shift, thus causing problems with the copper busbar bending.

[0029] First, a cylinder 1 is installed next to the cooling component 7. The output end of the cylinder 1 is hinged to one corner of the triangular plate 2, and the other two corners of the triangular plate 2 are hinged to the fixed plate 3 and the connecting member 4 respectively, and the connecting member 4 is fixedly connected to the mounting frame 51. When the copper busbar needs to be bent, the cylinder 1 is first started. The press on the surface of the cylinder 1 reflects the output length of the cylinder 1 at this time and the speed at which the output end of the cylinder 1 extends. The triangular plate 2 is driven by the cylinder 1 to move in the direction of the engaging component 5. At this time, the triangular plate 2 presses the fixed plate 3 and the connecting member 4. With the fixed plate 3 as the support point, the connecting member 4 is converted from an oblique position to a vertical position to support the mounting frame 51 so that the copper busbar can be bent.

[0030] At the same time, the longer the cylinder 1 extends, the farther the triangular plate 2 moves, and thus the higher the distance the mounting bracket 51 rises, thereby being able to change the bending angle of the copper busbar to adapt to various installation paths.

[0031] The cooling assembly 7 includes an air pump 71, a conductive shell 72, an air bag 73, and an air supply pipe 74; the air pump 71 is connected to the conductive shell 72, the conductive shell 72 is connected to the air bag 73, and the conductive shell 72 is connected to the air supply pipe 74; when the cylinder 1 drives the triangular plate 2 to move, the triangular plate 2 will press against the surface of the air bag 73, and the air pump 71 will transport gas into the conductive shell 72, and the gas in the conductive shell 72 will also flow into the air bag 73, pressing the air bag 73 through the triangular plate 2, so that the gas accommodation space in the air bag 73 becomes smaller, and at the same time, the air pump 71 transports gas into the conductive shell 72, so that the gas moves to the air supply pipe 74, thereby blowing air on the copper busbar to clean and cool it;

[0032] In addition, the air pipe 74 is a lifting pipe. When the mounting plate is raised or lowered, the air pipe 74 abuts against the mounting plate. When the mounting plate is raised or lowered, the position of the air pipe 74 will also change accordingly. When the bending machine bends the copper busbar at different angles, the air pipe 74 can clean and cool it.

[0033] The clamping assembly 5 includes a mounting frame 51, a moving block 52, a positioning rod 53, and a limiting wheel 54; the mounting frame 51 is slidably connected to the moving block 52, the moving block 52 is threadedly connected to the positioning rod 53, and the limiting wheel 54 is fixedly connected to the mounting frame 51; when the cylinder 1 drives the mounting plate to rise and fall, by placing the copper bar on the positioning rod 53 and rotating the positioning rod 53 at the same time, the two sets of moving blocks 52 move relative to each other, clamping the side of the copper bar to prevent it from deflecting during bending;

[0034] The movable block 52 is provided with multiple groups of holes, and two groups of the movable block 52 are symmetrically arranged along the long side direction of the mounting frame 51. When the copper busbar needs to be bent to different angles, the positioning rods 53 are inserted into different holes to change the distance between the copper busbar position and the press fitter 61, so that the bending angle of the copper busbar can be adjusted when it is bent. By adjusting the position of the positioning rods 53, the copper busbar can be bent at different angles, which facilitates the layout of power transmission.

[0035] At the same time, by installing the limiting wheel 54 on the mounting frame 51, the mounting frame 51 can only be vertically ascended or descended, preventing the copper busbar from deflecting when being bent, thereby achieving a better positioning effect.

[0036] The bending assembly 6 consists of a press fitter 61, a fixed shell 62, a limit piece 63, and a clamping piece 64; the press fitter 61 is slidably connected to the fixed shell 62, the fixed shell 62 is rotatably connected to the limit piece 63, and the clamping piece 64 is fixedly connected to the fixed shell 62; the press fitter 61 and the fixed shell 62 are limited by the rotation of the limit piece 63. When the limit piece 63 contacts the fixed shell 62 and the press fitter 61 at the same time, the press fitter 61 is fixed on the fixed shell 62 to prevent the press fitter 61 from deflecting. When the limit piece 63 only contacts the fixed shell 62, the limit piece 63 moves to the clamping piece 64, and the limit piece 63 is fixed by the clamping piece 64. At the same time, the press fitter 61 is slid out of the fixed shell 62, so that the press fitter 61 can be replaced at any time to prevent the press fitter 61 from being damaged and unable to be replaced in time, resulting in delays in work progress.

[0037] At the same time, the press fitter 61 contacts both sides of the copper bar at the contact position to limit the center of the copper bar, and the positioning rod 53 limits both ends of the copper bar to better prevent the copper bar from deflecting when bending.

[0038] Working principle:

[0039] When the copper busbar needs to be bent, the cylinder 1 is first started. The press on the surface of the cylinder 1 reflects the output length of the cylinder 1 at this time and the speed at which the output end of the cylinder 1 extends. The cylinder 1 drives the triangular plate 2 to move in the direction of the locking assembly 5. At this time, the triangular plate 2 presses the fixed plate 3 and the connecting member 4. With the fixed plate 3 as the support point, the connecting member 4 is converted from an oblique position to a vertical position to support the mounting frame 51 so as to bend the copper busbar. The triangular plate 2 presses the airbag 73 to reduce the gas placement space in the airbag 73. At the same time, the air pump 71 transports gas into the guide shell 72, so that the gas moves to the gas pipe 74, thereby blowing air on the copper busbar to clean and cool it. When the cylinder 1 drives the mounting plate to rise and fall, the copper busbar is placed on the positioning rod 53 and the positioning rod 53 is rotated at the same time, so that the two sets of moving blocks 52 move relative to each other, clamping the side of the copper busbar to prevent it from shifting during bending.
