OUTIL DE PRESSE POUR L’EMBOUTISSAGE D’UNE TOLE

摘要

The tool (10) has a key form (22) defining a pressing portion (24) for a sheet (12) in undercut designed to cooperate with a punch (18). The sheet is mounted movable on a supporting frame (14) according to a direction (A) between a pressing position and a retracted position. A cam (30a) drives the key form in displacement. A movable frame (16) moves relative to the supporting frame, and carries a presser (58) designed to press and maintain the sheet against the punch. The cam drives the key form in its pressing position by drawing the form toward outside of the punch.
