Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a punching device for processing copper busbars. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with a rectangular or chamfered rectangular cross-section. They function to transmit current and connect electrical equipment in circuits. Copper busbars have advantages such as low resistivity and high bendability. Because copper's conductivity is superior to aluminum, copper busbars are widely used in electrical equipment, especially in complete power distribution systems. A copper busbar shearing and punching device is an auxiliary device used in the copper busbar processing process to punch and shear holes in the busbars; it is widely used in the copper busbar production and processing industry.

[0003] Chinese Patent Publication No. CN 212884418 U discloses a "copper busbar punching and positioning device". The copper busbar punching and positioning fixture includes a copper busbar longitudinal positioning component, a copper busbar transverse positioning component, and a copper busbar punching component. The copper busbar punching component includes a mold support base fixedly mounted on a support base, a mold support mounting groove on the mold support base, and a punching mold embedded in the mold support mounting groove. A support top plate is connected to the punching mold via a support rod on the side of the support base away from the operating area. A hydraulic cylinder and a punching punch are mounted on the support top plate. The support base has a copper busbar longitudinal positioning component and a copper busbar transverse positioning component, respectively, corresponding to the width and length directions of the copper busbar workpiece. This utility model has a reasonable and novel design, a compact structure, and a high degree of automation. It allows for convenient and efficient replacement of the punching mold; it can automatically, efficiently, and accurately position the copper busbar workpiece, greatly improving the efficiency and accuracy of copper busbar punching and enhancing product quality.

[0004] In this patent, during the punching process of copper busbars, the position cannot be adjusted according to the size of the workpiece, and the top of the copper busbar is punched directly. The copper busbar lacks a limiting mechanism, which easily causes it to be unstable during punching and to deviate during the punching process, thereby affecting the punching quality. The debris generated after punching is completed is scattered, further reducing the operability of the device.

[0005] To address this, we propose a punching device for copper busbar processing. Utility Model Content
