Bimetal clad plate preparation method and device

Abstract

The invention relates to a bimetal clad plate preparation method and device. The method comprises the following steps that (1) a partition board is clamped between a base plate and a clad plate, and the parts to be combined of the base plate and the clad plate extend out from the side edge of the partition board and extend into a working area of an induction coil; (2) the induction coil is made toconduct instantaneous discharge to realize high-speed impact welding of the base plate to form a clad plate local welding area; (3) the induction coil in the step (2) is replaced with another deformed induction coil, one side edge of the bottom surface of the deformed induction coil is provided with a protrusion part protruding downwards, and the inward side face of the protrusion part is a bevelmatched with the slope of a plastic deformation part of the clad plate; and (4) the next sections of areas to be combined of the base plate and the clad plate are moved into the working area of the deformed section induction coil to enable the deformed induction coil to conduct instantaneous discharge to implement magnetic pulse welding on the areas to be combined of the two metal plates. The bimetal clad plate preparation method has the advantages that the production process is high in speed and efficiency and stable and reliable in quality, and the whole combination process is green and friendly to environment.

Description

technical field [0001] The invention relates to a method and a device for preparing a bimetal composite plate, and relates to the field of preparation of layered metal composite materials. Background technique [0002] Bimetallic composite panel refers to a layered composite material formed by combining metal sheets of different materials through a certain connection technology. The bimetal composite plate has both the excellent properties of the two metals (such as high hardness, high toughness, corrosion resistance, wear resistance, etc.), not only can meet the requirements of different working conditions, prolong the service life of the workpiece, but also greatly It greatly saves rare and precious metal materials, reduces production costs, and has good comprehensive economic benefits and market competitiveness. At present, bimetal composite panels are mainly used in anti-corrosion, pressure vessel manufacturing, light industry, automobile and other industries. [0003]...

AI Technical Summary

Problems solved by technology

Explosive compounding process can realize the compounding of various metals with high efficiency, but it has great pollution to the environment, the operation is dangerous, and the degree of mechanization is low.

Although the above traditional methods can realize the metallurgical connection of metal plates, the processing process is relatively complicated, the cycle is long, the investment in equipment is large, the repeatability of the parts is relatively low, and in the compounding process, excessive heat input is easy to combine Hard and brittle intermetallic compounds and heat-affected zones are produced at the interface, which sharply reduces the mechanical properties of the bonding interface and seriously affects the bonding strength of the composite plate
