Compressive force transmitting coupling (64) between an actuator (16), which oscillates along an arcuate path and a ram block (12) which reciprocates along a straight line path comprises first and second compression blocks (66, 68) and a bearing (70) between the compression blocks (66, 68). The compression blocks are in alignment and in compressive engagement with the ram block (12) and actuator (16). The compression blocks have opposed concave cylindrical bearing surfaces (72, 73) and the bearing (70) has oppositely facing convex bearing surfaces (74, 75) which are complementary to the concave surfaces (72, 73) of the blocks (66, 68).

Stamping and forming machine having improved couplings

A tooling module for use in a stamping and forming machine comprises a tooling portion and an actuator portion. The actuator portion is fixed to a reciprocable ram and the tooling portion is slidably carried by the actuator portion. The tooling portion is normally spaced from to the actuator portion and is movable to an adjacent position. The tooling portion has forming tooling thereon for performing a bending or other operation on strip material. The actuator portion has an actuator such as a cam for moving the forming tooling when the module is moved by the ram against the strip on which forming operations are being carried out.
