发明名称 SCRAP SHAPE RETENTION
摘要 Disclosed herein is a sheet metal stamping device and method for substantially inhibiting recoil from a neutral stamped position of a scrap part region. A sheet metal stamping device for stamping a sheet metal part comprising a first die body and a second is provided wherein the first die body and the second die body are in operable communication for forming the sheet metal part from a sheet metal blank. The sheet metal part includes at least one scrap region formed therein which is prone to recoil from a neutral stamped position. The first die body and the second die body have complementary elongate bead-forming regions located for forming an elongate bead region in the scrap region. And, the elongate bead-forming regions are configured such that the elongate bead substantially inhibits recoil or springback of the scrap region from the neutral stamped position when the scrap region is severed from the part. A method of stamping a sheet metal part having at least one scrap region prone to recoil formed therein utilizing the device and severing the scrap region is also disclosed.
