PRESS PROCESSING METHOD AND MOLDING DEVICE

摘要

In the present invention, in the state of the edge of a section to be processed of a work (11) comprising a metal plate being held, the molding protrusion (151) of a punch (15) is moved towards the molding recess (131) of a die (13). In such a manner, the work (11) is press processed, and a protrusion (12) is formed at the work (11). At the bottom dead center position of the punch (15), the inclined lateral wall sections (122) of the protrusion (12) are collapsed. In such a case, the work material of the lateral wall sections (122) moves to other portions of the work (11).
