ABSTRACT:
A process for stroke adjustment employs an adjustable stroke punch press which has a crankshaft with an integral eccentric portion around which is disposed an eccentric sleeve, a connection arm, an L-shaped piston-like sleeve, a locking plate, and a clamping plate. During press operation, the eccentric sleeve is locked to the crankshaft through the locking plate and the clamping plate. Stroke length is adjusted by changing the eccentricity of the integral crankshaft eccentric portion relative to the eccentric sleeve. The eccentric sleeve is unlocked from the crankshaft and locked to the connection arm during stroke adjustment allowing the crankshaft to rotate relative thereto by utilizing the inching mode of the press.
