ABSTRACT:
A multi-station strip metal forming press has a safety release mechanism for the transfer slide to protect the press components in the event of a jam or internal breakage. A press frame has a plurality of horizontally spaced work stations and supports a vertically reciprocable ram; a plurality of tools carried by and movable with the ram, positioned to be operatively disposed at the stations and cooperate with dies thereat to perform work on workpieces positioned at the work stations. A horizontally movable transfer slide and associated transfer rails are provided for carrying workpieces sequentially in a predetermined manner to the stations. A powered mechanism reciprocates said transfer slide and ram in timed relationship. A safety release mechanism for the transfer slide operatively disconnects the powered mechanism from said transfer slide on the occurrence of a jam anywhere in the press regardless of the point in the cycle of press operation or position of the jam and causes the transfer slide to stop.
