Copper busbar extrusion die and extrusion forming process

Abstract

The invention discloses a copper busbar extrusion die and an extrusion forming process. The copper busbar extrusion die comprises a rack, the rack is provided with an extrusion wheel and a riding wheel, the surface of the extrusion wheel is provided with an installation assembly and a protection assembly, the rack is fixedly connected with a rotating motor, an extrusion rod is arranged between the extrusion wheel and the riding wheel, an extrusion die body is arranged on one side of the rack, a feeding opening is formed in the side, close to the rack, of the extrusion die body, a guide assembly is arranged at the top of the feeding opening, a rotating shaft is movably connected to the top of the feeding opening, a gear groove is formed in the outer surface of one side of the rotating shaft, a driving assembly is arranged on one side of the guide assembly, an extrusion cavity is formed in the side, away from the extrusion wheel, of the feeding opening, and a discharging opening is formed in one side of the extrusion cavity. According to the copper busbar extrusion die and the extrusion forming process, by arranging a friction sleeve, the friction force between the extrusion wheel and the extrusion rod can be enhanced; and by arranging an electric push rod and a control button, the friction sleeve can be better replaced.

Description

technical field [0001] The invention relates to the technical field of copper busbar manufacturing, in particular to a copper busbar extrusion die and an extrusion molding process. Background technique [0002] Copper bus bar is the main variety of copper plate and strip, which is used to collect, distribute and transmit electric energy, and is widely used in various power transmission and transformation equipment. With the development of high-tech industries, the comprehensive performance requirements of copper busbar products are getting higher and higher. On the basis of high strength and high conductivity, the best possible toughness is also required. Toughness is the comprehensive performance of material strength and plasticity. Generally, it is contradictory to increase the strength and plasticity of materials at the same time. Therefore, it is necessary to study the microstructure and grain size of the material in connection with the production process of the copper ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a copper bus bar extrusion die and extrusion molding process for the disadvantages of the prior art, which is used to solve the problem that the friction between the existing extrusion wheel and the blank is weak and the heating effect is relatively weak. Poor, after long-term use of the extrusion wheel, the extrusion wheel will be worn out, and the replacement of the extrusion wheel is more troublesome, the extrusion rod is vertically upward, and the feeding port is set horizontally, which is not conducive to extrusion The rod enters the feed port. If the guide wheel is used to push the extruded rod into the feed port, the guide wheel is susceptible to wear after long-term use.
