Abstract

The parts to be finished on the press have already been part- or finish- machined and are subjected in the press to pressure on its end faces in order to stabilise its form or to equalise its mechanical characteristics. The compression force is exerted by two dies which act at right angles to the force which was exerted to bend or twist the part. The arrangement consists of a rigid movable plate (1) which is mounted on a base (9). Knee levers (16) are mounted in the plate which control the two compression dies. The knee levers increase the force which is exerted on the dies. One lever arm (OB) acts against a die, the other lever arm (OA) is at right angles to the first one. A piston (17) acts against this arm. The plate (1) is moved upward by means of pillars to exert the force required to bend or twist the workpiece just before the sideways compression force is exerted by the levers. The end of the sideways compression of the workpiece coincides with the end of the lifting movement of the plate.
