Description

Technical Field

[0001] This utility model relates to the field of copper busbar bending, and more specifically, to a busbar bending device. Background Technology

[0002] Copper busbars are key conductor components used for power transmission and distribution, widely applied in high and low voltage power distribution systems, new energy equipment (such as photovoltaic inverters, energy storage systems, and electric vehicle battery packs), and industrial control cabinets. Their core function is to carry large currents (hundreds to thousands of amperes), and they are formed into specific structures through bending, punching, and other processing techniques to meet requirements for electrical connections, spatial layout, and heat dissipation. This is especially important with the rapid development of industries such as new energy, electric vehicles, and data centers.

[0003] Traditional busbar bending relies on manual operation or semi-automatic machinery. This method can reduce costs compared to automated equipment and is more suitable for small-batch production. The production cost of bending angle molds is also relatively low. However, when bending copper busbars, micro-cracks or surface scratches are easily generated due to stress concentration. For example, the busbar bending machine with announcement number CN202490856U has poor versatility, requires frequent changes of bending fixtures, and lacks positioning during manual processing, often requiring workers to rely on experience, which can sometimes lead to material waste. Utility Model Content

[0004] The purpose of this utility model is to provide a busbar bending device, wherein the installation position of the threaded adjustment hole on the push plate frame can be changed to match the replacement bending block, thereby improving the applicability of the device; the upper limit block, rotating column, and lower limit block are made of nylon material, which protects the bent busbar copper busbar from wear; the rotating column and lower limit block can rotate relative to the busbar copper busbar, which also prevents the busbar copper busbar from being worn to a certain extent.

[0005] This utility model is achieved through the following technical solution:

[0006] A busbar bending device includes a platform plate. A bending device is provided on one side of the platform plate, and an arc-shaped bending block is provided at the front end of the bending device.

The pushing device includes an upper limit block and a lower limit block. A rotating column is provided between the upper limit block and the lower limit block.

The upper limit block and the lower limit block are round blocks. The fixing bolt above the lower limit block is provided with a rotating column through a bearing. The center of the upper limit block is threadedly connected to the fixing bolt through a threaded ring. The fixing bolts at the lower limit block and the rotating column are not threaded.

[0008] Furthermore, the upper limit block, lower limit block, and rotating column are all made of nylon.

[0009] Furthermore, the bending device includes a mounting base, which is fixed on the platform plate. The front end of the mounting base is provided with a connector, and the bending block is provided with a connector groove. The connector and the connector groove cooperate, and the bending block is fixed on the platform plate by bolts.

[0010] Furthermore, the front end of the bending block is an arc-shaped bending groove, and an arc-shaped nylon plate is provided inside the arc-shaped bending groove.

[0011] Furthermore, a limiting baffle is provided on one side of the platform plate of the pusher frame, and one end of the busbar copper busbar is positioned on the limiting baffle during processing.

[0020] The present invention will now be further described in conjunction with the accompanying drawings.

[0021] like Figure 1 – Figure 3 As shown in Embodiment 1, a busbar bending device includes a platform plate 1. A bending device is provided on one side of the platform plate 1, and an arc-shaped bending block 4 is provided at the front end of the bending device. An installation groove 10 is provided on the other side of the platform plate 1. A hydraulic cylinder 9 is provided in the installation groove 10. A push plate frame 5 is slidably provided in the installation groove 10 (the push plate frame 5 moves in the installation groove 10 and can play a certain limiting role). The piston rod of the hydraulic cylinder 9 is connected to the push plate frame 5. Several threaded adjustment holes 7 are symmetrically provided on both sides of the push plate frame 5. A pushing device is symmetrically provided in the threaded adjustment holes 7 on both sides. The pushing device includes an upper limit block 11 and a lower limit block 13. A rotating column 12 is provided between the upper limit block 11 and the lower limit block 13. The upper limit block 11, the lower limit block 13 and the rotating column 12 are installed by limiting fixing parts.

[0022] Example 2: A busbar bending device, wherein the limiting and fixing component is a fixing bolt 6, the two ends of the fixing bolt 6 are threaded and installed between the upper and lower plates of the push plate frame 5. The upper limit block 11 and the lower limit block 13 are round blocks. A rotating column 12 is provided on the fixing bolt 6 above the lower limit block 13 via a bearing. The center of the upper limit block 11 is threadedly connected to the fixing bolt 6 via a threaded ring. The fixing bolts 6 at the lower limit block 13 and the rotating column 12 are unthreaded. The upper limit block 11, the lower limit block 13, and the rotating column 12 are all... The bending device is made of nylon. It includes a mounting base 2, which is fixed on the platform plate 1. The front end of the mounting base 2 is provided with a connector 3, and the bending block 4 is provided with a connector groove. The connector 3 and the connector groove cooperate, and the bending block 4 is fixed on the platform plate 1 by bolts. The front end of the bending block 4 is an arc-shaped bending groove, and an arc-shaped nylon plate 8 is provided in the arc-shaped bending groove. The platform plate 1 on one side of the push plate frame 5 is provided with a limiting baffle 14. One end of the busbar copper busbar is positioned on the limiting baffle 14 during processing. The rest is the same as in embodiment 1.

[0023] In use, select a bending block 4 with a suitable curvature for installation and fixing according to the required bending of the busbar copper busbar, and adjust the installation position of the pushing devices on both sides. Since the installation position of the pushing devices can be adjusted on both sides of the push plate frame 5, only the bending block 4 needs to be replaced as needed, which increases the versatility of this utility model. Place the busbar copper busbar on the lower limit block 13, and position one end of the busbar copper busbar against the limit baffle 14. According to the thickness of the busbar copper busbar, rotate and adjust the upper limit block 11 so that the upper limit block 11 and the lower limit block 13 limit the busbar copper busbar to be processed to a certain extent (a certain gap can be left between the upper limit block 11 and the busbar copper busbar so that the lower limit block 13 and the rotating column 12 can rotate during the processing of the busbar copper busbar, which helps to ensure the bending quality and prevent scratching the busbar copper busbar). The hydraulic cylinder 9 pushes the push plate frame 5, and the rotating columns 12 on both sides can rotate and push the busbar copper busbar to bend around the arc-shaped nylon plate 8. The corresponding bending block 4 can be quickly replaced according to bending requirements, thereby improving the adaptability of this utility model.
