Device and method for preparing metal composite material with coating structure through bidirectional extrusion

Abstract

The invention discloses a device and a method for preparing a metal composite material of a coating structure through bidirectional extrusion, and belongs to the technical field of metal composite material machining. The device comprises a fixed support, a combined extrusion die, an extrusion male die, an extrusion container, a forward extrusion device and a backward extrusion device, the combined extrusion die is arranged between the forward extrusion device and the backward extrusion device, a mounting base sleeves the outer side of the combined extrusion die and is fixedly connected with the fixed support, a forward extrusion female die is arranged at one end in the combined extrusion die, a backward extrusion female die is arranged at the other end, one end of the extrusion male die is matched with the forward extrusion female die, the other end of the extrusion male die is matched with the forward extrusion device, one end of the extrusion cylinder is matched with the backward extrusion female die, and the other end of the extrusion cylinder is matched with the backward extrusion device. According to the device and the method for preparing the metal composite material of the coating structure through bidirectional extrusion, blank defects are eliminated by extruding an inner-layer blank, a new metal surface is generated, and the composite material with high surface binding force and excellent material mechanical property is obtained through subsequent extrusion composite forming.

Description

Technical field

[0001] The present invention belongs to the processing of the metal composite material, and in particular, to a two-way extrusion prepared apparatus and method of a metal composite material.Background technique

[0002] The metal composite material is a new composite material prepared by a metal having a solid metallurgy in the interface using a composite technique to make two or more metallurgical metallurgy in the interface. The metal composite material has a single metal material is unparalleled, and the appropriate material is selected and appropriately combined, not only the own characteristics of the composition material can be retained, but also to make the properties of the composition material complement each other to obtain the composite material. Excellent overall performance. Copper clad aluminum, copper-clad steel, aluminum pack magnesium pack magnesium and other composites, more and more applications in signal transmission, electricity delivery, transportatio...
