ABSTRACT:
A die set (24) for use with a stamping and forming machine (10) includes two opposed tooling plates (50, 52) arranged to undergo reciprocating motion with respect to a base plate (40) toward and away from a strip of material (30) that is fed along a feed path (38) between the two ram plates (50, 52). Each ram plate has a tooling attachment plate (58, 60) having tool mounting surfaces (62, 64) facing inwardly toward the feed path (38) for the attachment of punch and die tooling assemblies (26, 28) for performing the stamping and forming operations on the strip of material. Each of the ram plates (50, 52) includes a shut height adjusting mechanism (100) associated with each tooling attachment plate (58, 60) for adjusting the shut height of individual tooling. Additionally, each of the ram plates (50, 52) includes a stripper plate actuating mechanism (140) associated with each tooling attachment plate (58, 60) for actuating the stripper plates (162) of each individual tooling unit (86) as well as adjusting the spring force on each stripper plate (162).
