Abstract:
A forging machine comprising(a) a forging box,(b) a plurality of connecting rods, each connecting rod having an axis and carrying a forging tool at one end thereof,(c) an eccentric drive for driving each connecting rod in a reciprocating motion, the drive including(1) a shaft having an axis and comprising an eccentric, the reciprocating motion extending radially to the eccentric shaft axis and the connecting rod being supported against axial displacement,(2) a bearing body rotatably and axially displaceably mounted on the eccentric, and(3) a head at an end of the connecting rod opposite to the one end,(4) the bearing body and the connecting rod head having corresponding inclined surfaces in non-rotating and sliding engagement to form a sliding path which is inclined to the axis of the shaft and extends in a plane extending perpendicularly to a plane defined by the axes of the connecting rod and the shaft, and(d) an actuator for axially displacing the bearing body.
