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

Abstract

The invention discloses an electroplasticity assisted laser shock deep drawing forming device and method, relates to the field of laser shock forming technology and electroplastic assisted forming, including a laser shock device and a die deep drawing device; the sheet material is arranged on the die stretching device In the process, the sheet is formed by the die stretching device, and the laser shock device is used to assist the processing of the sheet by changing the transmission path of the laser. The laser shock forming is carried out while the sheet is deep-drawn, which improves the forming ability of the sheet metal deep-drawing, overcomes the inconsistency of the forming time of the laser shock forming and the electric-assisted forming, and improves the efficiency of the laser shock forming.

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...
