Title:
METHOD FOR REDUCING SPRINGBACK USING ELECTRICALLY-ASSISTED MANUFACTURING
Document Type and Number:
WIPO Patent Application WO/2016/057688
Kind Code:
A8
Abstract:
A process for forming a sheet metal component. The process includes rigidly clamping a piece of sheet metal to a clamping fixture and plastically deforming the sheet metal to produce a shaped component during a first manufacturing step. The shaped component has a first amount of springback. During a second manufacturing step, a pair of electrodes applies one or more pulses of electrical current at one or more locations on the shaped component while the shaped component is still rigidly clamped to the clamping fixture during. The one or more pulses of electrical current applied to the shaped component provide an electrically-assisted manufactured (EAM) shaped component. The EAM shaped component has a second amount of springback that is less than the first amount of springback.
