Electroplastic auxiliary laser shock drawing forming device and method

Abstract

The invention discloses an electroplastic auxiliary laser shock drawing forming device and a method, and relates to a laser shock forming technology and the field of electroplastic auxiliary forming.The electroplastic auxiliary laser shock drawing forming device comprises a laser shock device and a trimming die drawing device; a plate material is arranged in the trimming die drawing device, forming is executed for the plate material through the trimming die drawing device, and the laser shock device performs auxiliary processing for the plate material through changing a transmission way of laser. While drawing forming is executed for the plate material, laser shock forming is also executed, thus, forming capability of plate material drawing forming is improved, incompatibility of formingtime of laser shock forming and electric auxiliary forming is overcome, and efficiency of laser shock forming is improved.

Description

technical field [0001] The present invention relates to the field of laser forming technology and electric assisted forming technology, in particular to a method and device for realizing continuous impact of pulsed laser under the condition of pulsed current and simultaneously drawing and forming sheet metal. It is especially suitable for laser shock forming of difficult-to-form metal sheets. Background technique [0002] Bending forming of sheet metal has always played an important role in aerospace, automobile, shipbuilding and civil industries. The traditional die stamping is to place the metal sheet on the mold, and under the action of the press, an internal force that deforms the sheet is generated inside the sheet to form a certain shape of the part. Although the operation is simple and the production efficiency is high, the production preparation time is long. , poor processing flexibility, large mold costs, high manufacturing costs, etc., and is limited by the formi...

AI Technical Summary

Problems solved by technology

Since the laser shock forming takes a long time and the electric-assisted forming does not require a process time, the present invention introduces stamping forming, which overcomes the inconsistency of forming time between laser shock forming and electric-assisted forming, and combines laser shock forming with electric-assisted forming and stamping forming. Combined, it overcomes the shortcomings of a single laser shock forming process
