Abstract

The invention discloses a light alloy rolling compound forming process with controllable edge cracking, which belongs to the technical field of light alloy plate compound forming process. Alloy liner, the alloy plate and the hard liner are heated and rolled together. The grooves can effectively control the edge cracks during the rolling process; the protrusions cooperate with the rolls to cause local severe shear deformation of the alloy plate during the rolling process, promote the widening of the plate along the transverse direction, and weaken the texture Effect. The entire liner is the same as the liner rolling in the composite forming process, which can increase the single-pass reduction, reduce the rolling passes, reduce the rolling temperature, and more effectively refine the grain size. Under the premise of controllable edge cracking, the whole deformation process can be regarded as the compound superposition of rolling, shearing and widening deformation of the lining plate. The whole technological process is simple and easy to realize, and has good industrial application prospect.

Description

technical field

[0001] The invention belongs to the technical field of compound forming technology of light alloy plates, in particular to a rolling-shearing-widening compound forming process of high-performance light alloy plates with controllable edge cracking, and belongs to the technical field of metal compound forming processing. Background technique

[0002] With the increasing demand for energy saving and emission reduction in my country, lightweight has become an irreversible trend in the field of metal applications. As a light alloy material with relatively low density, it is expected to be widely used in automobiles, electrical appliances, aerospace and other fields. Currently commonly used light alloys are mainly magnesium alloys, aluminum alloys and titanium alloys. Among them, magnesium and magnesium alloys are currently the lightest metal structural materials in engineering applications. They have high specific strength and specific stiffness, good electrical ...
