Abstract:
My invention relates to apparatus for forging crank shafts, and more particularly to a set of dies and their fittings and supports adapted to be operated by power for the bending and forging of crank shafts. The apparatus herein to be disclosed is shown of a nature permitting it to be employed on various power operated machines or presses whether horizontal or vertical, such for example as the ordinary punching press or a hydraulic press or the machine know n as a bulldozer; there being in each instance a reciprocating part such as the crosshead of the bulldozer, with which certain of the die mechanism cooperates, and a stationary member to which other parts of the die mechanism are secured. The present improvements are particularly intended to be operated by power in one way or another. An object of the present invention is to enable the production of crank shafts with full stock at the corner of the bends and in an efficient and satisfactory way, this being one of the problems with which forge shops have always contended. Another object is to permit the bending of the shaft and the upsetting or the formation of full stock at the corners in a single operation and by the single apparatus hereof. Crank shafts made in a drop forge have required a tedious and expensive operation and machinery. the finished shaft being forged down out of large sized material and the material thereby considerably distorted.
Claim:
In a crank shaft forging apparatus, the combination of an actuator adapted to make a forward stroke, mechanism actuated by said actuator operative in the first part of each forward stroke for producing all the bends of the crank, and mechanism actuated by said actuator operative in the last part of each forward stroke thereof for upsetting the corners by displacing the crank wrist relatively toward the shaft line. 2In a crank shaft forging apparatus the combination of a movable actuator or head, a shaft bending means for making all the bends of the crank, connections whereby the actuator actuates said bending means, and an upsetting die for displacing the crank wrist toward the shaft line after said bending means has bent the shaft, and connections whereby the actuator actuates said die, said respective connections being such that a single operation of the actuator causes the operations in the order named. |
