Description

Technical Field

[0001] This utility model relates to busbar processing equipment technology, specifically a busbar bending die. Background Technology

[0002] Busbars are widely used in electrical equipment, and bending is a key process in busbar production. Traditional busbar bending dies adopt a dedicated design of "one die for one product," meaning that a set of dedicated dies is required for each type of busbar bending specification.

[0003] The existing technology has obvious drawbacks: First, the mold has poor versatility. When dealing with busbars of various specifications or multiple bending processes, multiple sets of special molds are required, resulting in high mold procurement and manufacturing costs. Second, the mold changing process is cumbersome. Frequent disassembly and installation of the entire mold is not only time-consuming and labor-intensive, but also reduces production efficiency. Third, the traditional mold has a bulky overall structure, which poses safety risks during handling and installation. In addition, the mold has low ductility and cannot adapt to flexible production needs.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a motherboard bending die to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a female mold for bending busbars, which solves the problems of high cost, slow mold change, and poor safety of traditional special molds, and realizes efficient and low-cost processing of busbars of various specifications.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a busbar bending die, comprising upper and lower correspondingly arranged components:

[0007] The lower bending die is composed of a lower die mother die and a lower die daughter die. The lower die mother die is fixed on the base of the bending machine, and the lower die daughter die is detachably fixed on the top side of the lower die mother die. The top side of the lower die daughter die forms a lower bending surface.

[0008] The upper bending die is composed of an upper die mother die and an upper die daughter die. The upper die mother die is fixed to the bottom side of the output end of the hydraulic cylinder of the bending machine, and the upper die daughter die is detachably fixed to the bottom side of the upper die mother die. The bottom side of the upper die daughter die forms an upper bending surface.

[0009] The upper bending surface and the lower bending surface correspond to each other and form a busbar bending structure.

[0010] A preferred technical solution is as follows: a lower pin groove with a square cross-section is formed on the top side of the lower mold mother mold, and a lower positioning pin with a square cross-section is formed on the bottom side of the lower mold sub-mold. The lower mold sub-mold is pinned and positioned in the lower pin groove on the lower mold mother mold by the lower positioning pin.

[0011] A preferred technical solution is as follows: the bottom side of the upper mold mother mold has an upper pin groove with a T-shaped cross section, the top side of the upper mold daughter mold has an upper positioning pin with a T-shaped cross section, and the upper mold daughter mold is pinned and positioned in the upper pin groove of the upper mold mother mold by the upper positioning pin.

[0012] The preferred technical solution is as follows: a magnet is embedded in the bottom of the lower pin groove, and a magnet is embedded in the bottom side of the lower positioning pin. The magnetic poles of the magnet and the magnet are opposite and correspondingly arranged.

[0013] The preferred technical solution is as follows: a magnet three is embedded in the bottom of the upper pin groove, and a magnet four is embedded in the top side of the upper positioning pin. The magnetic poles of the magnet three and the magnet four are opposite and correspondingly arranged.

[0014] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] Reduce mold costs: A single master mold can be used with dozens or even hundreds of seed molds, eliminating the need to make a complete set of molds for each specification of busbar, thus significantly reducing mold procurement and manufacturing costs.

[0016] Improve mold changing efficiency: The sub-mold is small in size and light in weight. It can be quickly positioned and installed by the cooperation of the positioning pin and the magnet. There is no need to disassemble the entire mold, making the mold changing process efficient and convenient.

[0017] Improved operational safety: The sub-mold is lightweight and flexible to handle and install, avoiding the safety risks associated with handling traditional heavy molds and reducing operational difficulty.

[0018] Enhanced processing versatility: For complex busbars with irregular shapes or multiple bends, the processing can be completed by changing the sub-molds in different positions in one clamping, without the need for repeated clamping, thus improving processing accuracy and production efficiency.
