Problems solved by technology

At present, the mainstream processing and production of copper-aluminum composite strips use square copper and aluminum ingots, which are cold-rolled and composited into plates with a large amount of processing deformation. After that, the copper-aluminum composite strips are cut into copper-aluminum composite strips. When making copper and aluminum strips, large-thickness copper and aluminum strips are required to be rolled, but large-thickness copper and aluminum strips cannot be formed into circles, and only straight copper and aluminum strips can be used, and the length will not exceed 12 meters, it cannot form a large length, and it cannot be continuously extruded to produce copper-aluminum composite strips
Therefore, the existing copper-aluminum composite strip processing technology has problems such as long process flow, low yield, and high cost of making copper-aluminum composite strip, so it is not the best process method

Abstract

The invention provides a copper-aluminum composite double-row continuous extrusion module and a continuous extruder, the copper-aluminum composite double-row continuous extrusion module comprises an extrusion die with an extrusion die cavity, an extrusion die mounted in the extrusion die cavity, and a double-groove extrusion wheel with extrusion grooves, the extrusion die cavity can allow double copper bars to enter, the extrusion die is provided with extrusion convex parts which are oppositely arranged up and down in the extrusion die cavity and a clamping groove formed between the two extrusion convex parts, the clamping groove is provided with two copper bar extrusion die cavities which are symmetrically arranged left and right, and the two copper bars are contained in the two copper bar extrusion die cavities respectively. Two extrusion grooves are formed in the double-groove extrusion wheel and are symmetrically distributed on the left side and the right side of the extrusion die cavity, and the tail ends of the two extrusion grooves extend to the outer sides of the two copper bar extrusion die cavities respectively. The copper-aluminum composite bar with one side made of copper and the other side made of aluminum can be continuously extruded and produced, the copper-aluminum composite bar is double in number, the production efficiency of the copper-aluminum composite bar is greatly improved, process waste is reduced, production procedures are reduced, energy consumption is reduced, and operators are reduced.

Description

technical field [0001] The invention relates to the field of processing copper-aluminum composite materials, in particular to a copper-aluminum composite double-row continuous extrusion die set and a continuous extrusion machine. Background technique [0002] One side of the copper-aluminum composite tape is copper and the other side is aluminum. Copper and aluminum form a physical combination between molecules and are used for conductive materials. For example, new energy battery electrodes require large-length copper-aluminum composite strips as raw materials; copper-aluminum joints, electrical equipment, electronic strips, and electronic strips all require copper-aluminum composite strips as raw materials. Therefore, copper-aluminum composite tape is a functional material with a wide range of applications. [0003] Since copper and aluminum will form a powder phase at a temperature above 500°C, and the two cannot be bonded, the composite of copper and aluminum can only b...
