ABSTRACT:
Disclosed is a crankshaft forming apparatus and method which has forming heads for forming throw sections at any angle 360.degree. about the rotational axis of the crankshaft and orienting the full length of the throw sections of the crankshaft. The throws are checked for parallelism to the rotational axis of the crankshaft. By turning suitable actuators such as screws, the forming heads are pivoted about a vertical and/or horizontal axis to adjust the throw formation relative to the longitudinal axis. In this manner, each forming head may be adjusted in position until all of the respective throws being formed are parallel to the rotational axis of the crankshaft. Also provided is a toggle mechanism which clamps tightly a rod being formed and opens and closes the clamping units for insertion and removal of the rod.
