ABSTRACT:
A stamping and forming machine is disclosed having two operating modules with their drive shafts rotationally coupled together. Each module of the machine includes a punch assembly and a mating die assembly that reciprocate horizontally toward and away from each other for performing stamping and forming operations. The rotary motion of the drive shafts effects the reciprocation of the tooling by means of eccentric couplings attached to the drive shafts that drive eccentric links that in turn pivot actuating levers coupled to the tooling. Each module includes an independent feed mechanism that intermittently advances a strip of stock through the module in timed relation to the reciprocating motion of the tooling. The eccentric coupling of the first and second modules are angularly positioned about 120 degrees apart so that during operation, one of the modules has at least partially completed its stamping and forming operation prior to the other module beginning its respective stamping and forming operation, thereby reducing peak loading on the motors driving the drive shafts.
