Technical Field

[0001] This utility model relates to the field of copper busbar processing technology, and in particular to a copper busbar bending device for busbar copper busbar processing. Background Technology

[0002] In the installation of power equipment and the construction of power distribution systems, copper busbars, as key components for high-current transmission, often require twisting and bending to adapt to different wiring requirements. Traditional copper busbar processing mainly relies on large hydraulic bending machines or specialized twisting equipment, but these devices have the following problems:

[0003] First, they are not portable. Large equipment is bulky and heavy, making it difficult to use in confined working environments, especially unsuitable for temporary outdoor construction or small-scale power distribution renovation projects. Second, they are expensive. Professional bending machines or twisting equipment are costly to purchase and maintain, placing a significant financial burden on small and medium-sized power construction teams or maintenance personnel.

[0004] Therefore, there is an urgent need for a copper busbar bending device that is simple in structure, portable, easy to use, and inexpensive for processing copper busbars. Utility Model Content

[0005] The purpose of this invention is to provide a copper busbar bending device for processing busbars, which is simple in structure, portable and easy to use, low in cost, and highly practical.

[0019] Figure 2 This is a schematic diagram of the support frame structure according to an embodiment of this application. Detailed Implementation

[0020] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0021] like Figures 1 to 2The present invention discloses a copper busbar bending device for processing busbars, comprising a support frame 1, a receiving groove 2 extending along its length through the middle of the support frame 1, and a bending part 3 coaxially and movably disposed at the end of the support frame 1. The bending part 3 has a limiting groove 4 corresponding to the receiving groove 2. During operation, the copper busbar is first inserted into the lower limiting groove 4, and then the bending part 3 is fitted over the copper busbar using the receiving groove 2. The distance between the bending part 3 and the support frame 1 is adjusted according to the bending position of the copper busbar. Then, the bending part 3 is rotated to a certain angle, thus completing the bending and twisting of the copper busbar at the position between the bending part 3 and the support frame 1. After the operation is completed, the bending part 3 is removed, and the copper busbar is taken off. To ensure the effect of bending and twisting the copper busbar, in this embodiment, the limiting groove 4 and the receiving groove 2 are usually matched with the size of the copper busbar to be bent.

[0022] Specifically, the bending part 3 includes a connecting plate 3-1 at the bottom and a bending plate 3-2 disposed on the connecting plate 3-1; a limiting groove 4 is formed on the bending plate 3-2, and operating rods 3-3 are symmetrically arranged on the bending plate 3-2, extending radially along the bending plate 3-2 to improve the convenience of rotating the bending plate 3-2 during operation; a pointer 5 is also provided on the bending plate 3-2, and angle scale lines are provided on the top surface of the connecting plate 3-1 along its circumference, so that the operator can intuitively understand the angle of rotation of the bending plate 3-2, thereby completing the on-demand processing operation of the copper busbar and enhancing the practicality of this utility model. In addition, multiple threaded sleeves 6 are provided on the support frame 1 along its circumference, and each threaded sleeve 6 is threaded with a support screw 7 parallel to its axis. In the working state, the top of the support screw 7 contacts the bottom of the connecting plate 3-1; by adjusting the length of the support screw 7 extending to the top of the support frame 1, the bottom of the connecting plate 3-1 can be limited and supported during operation, thereby adjusting the length of the copper busbar bending and twisting as needed, that is, the length between the bottom of the connecting plate 3-1 and the top of the support frame 1, thereby expanding the scope of application of this utility model and enhancing its practicality.

[0023] Furthermore, adjusting blocks 8 are movably disposed within both the receiving groove 2 and the limiting groove 4; adjusting screws 9, which are rotatably connected to the adjusting blocks 8, are threaded onto both the bending portion 3 and the support frame 1. By rotating the adjusting screws 9, the movement of the adjusting blocks 8 within the receiving groove 2 and the limiting groove 4 can be controlled to fix the copper busbar, thereby meeting the processing requirements of copper busbars of various thicknesses. Preferably, the length of the adjusting block 8 is equal to the length of the limiting groove 4 to ensure the contact area with the copper busbar and enhance the stability of the non-bending portion 3 of the copper busbar during processing. In addition, guide grooves 10 are provided on the side walls of both the limiting groove 4 and the receiving groove 2, and guide blocks that slide within the guide grooves 10 are provided on the adjusting block 8 to ensure the stability of the adjusting block 8 during movement.

[0024] Furthermore, the support frame 1 is a hollow cylindrical structure. A slot 11 is provided on one side of the support frame 1 to connect with its internal guide cylinder. Multiple counterweights 12 are movably mounted inside the support frame 1 through the slot 11. The counterweights 12 increase the overall weight of the support frame 1, ensuring that the external force applied when the rotating bending part 3 processes the copper busbar will not cause the support frame 1 to move. Simultaneously, the slot 11 facilitates the removal of the counterweights 12, providing convenience for the transport of the entire device. Preferably, a cylindrical cavity is formed inside the support frame 1, and the counterweights 12 are disc-shaped and match the cavity. A support sleeve 13 is vertically mounted inside the cavity of the support frame 1. The support sleeve 13 is hollow and communicates with the receiving groove 2 to accommodate the copper busbar. The support sleeve 13 also provides support for the middle of the support frame 1, enhancing its stability. An clearance groove is provided on the counterweights 12, allowing them to fit over the support sleeve 13.

[0025] In use, the support frame 1 is placed at the work site, and the counterweight 12 is placed in the cavity of the support frame 1 through the slot 11. Then, the copper busbar is inserted into the receiving slot 2, and the adjusting screw 9 is rotated to move the adjusting block 8 to fix and clamp the copper busbar. The position of the supporting screw 7 is adjusted according to the bending and twisting distance of the copper busbar. Finally, the bending disc 3-2 is fitted on the top of the copper busbar, so that the connecting disc 3-1 abuts against the supporting screw 7. The adjusting screw 9 is rotated, and the adjusting block 8 is used to clamp and fix the copper busbar. Then, the operating rod 3-3 is held to drive the bending disc 3-2 to rotate and move the angle. The operation is simple and quick, the structure is simple, it can be flexibly applied to places with limited space or temporary outdoor construction, it is easy to carry, transport and store, the manufacturing cost is low, and it is highly practical.
