Abstract

Hydraulic press for stamping, bending, punching has a single operating handle and has a multiple control device for the oil flow, which is affected by the operating handle and the punch and whose parts are coupled by gearing components. There is an oil pump for pressure generation and for moving the punch while an additional oil pump operates a fast raise and lower for the punch. The punch also has an adjustable depth stop and rotation prevention and there is a two-hand safety circuit. Specif., the operating handle is coupled with the control shaft by means of a torsion spring, which holds the handle in the rest position.
