Problems solved by technology

However, compound fine blanking is generally carried out in a cold state, so local deformation is severe and the forming load is huge during the volume forming of medium and thick plates, resulting in generally low life of the die. How to reduce the volume forming of medium and heavy plates in compound fine blanking Load, so as to improve the life of the die is a big problem that still needs to be solved in the production of composite fine blanking

Abstract

The invention discloses a medium-thick plate differential thermal volume forming device and process. Positions with forming characteristics on plates are subjected to local sensing heating, and the heating temperature does not exceed the recrystallization temperature; the locally heated plates are graded to a next process to be subjected to local volume forming. By means of the device and the process, the plate volume forming load can be reduced effectively, and the die service life is prolonged.

Description

technical field [0001] The invention belongs to the field of composite fine blanking forming, and in particular relates to a medium-thick plate differential thermal volume forming device and process. Background technique [0002] Fine blanking is a fine blanking method developed on the basis of ordinary blanking. This technology can obtain parts with high dimensional accuracy and good cross-section quality through unique mold structure design and reasonable structural parameter settings. It is directly used in production without subsequent processing, which greatly improves the production efficiency of the product and reduces the production cost. At present, this technology is widely used in aerospace, mechatronics and other fields. Composite fine blanking refers to the fine blanking of the contour of the part and other forming processes (such as bending, flanging, flattening, upsetting, extrusion, countersinking, etc.) Forming process) is a processing method combined in o...
