Abstract
An infinite variable slide motion for a mechanical power press is achieved by use of a differential located on the press drive system. Differential movement means are employed to rotate the differential relative to the drive system so that the output of the differential may be increased or decreased relative to the drive system.
Claims1
A method of varying the slide motion in a running mechanical press, comprising:
- connecting a differential to a press drive system having a single motor and a press crankshaft;
- and
- utilizing the diferential to alternatively add and substract to the rotational velocity of the press crankshaft relative to the rotational velocity of the press drive system output.
