ABSTRACT:
Punching, shearing or bending operations are performed at different work stations along a common machine bed by selectively withdrawing coupling pins interconnecting adjacent tool carrying members supported by a pair of guide rods along which relative movement is imparted to uncoupled tool carrying members by a power operated piston rod connected to one of the slidable tool carrying members. Adjustable work support and guide facilities are provided at each of the work stations.
