Abstract: The crank assembly of the advancing apparatus is eccentrically supported in an intermediate shaft. This intermediate shaft is in turn supported in an oscillating slide. Accordingly, the oscillating movement of the slide is superimposed over such of the driving pivot of the crank assembly. The intermediate shaft includes a cam disk. Due to the cam disk the intermediate shaft oscillates in operation and causes in turn the oscillating movement of the slide, which oscillating movement proceeds oppositely to the oscillating movement of the driving pivot. The sum of these two movements in the zones of the end positions thereof is accordingly zero. Accordingly, the driving pivot is at rest over a prolonged time span. Due to this prolonged rest period between individual feeding steps, elastical deformations of working structures and of the workpiece being worked upon, can attenuate and fade out prior to the working proper, and at the same time the length of the advancing is not subjected to a change.

In the variable unit, the tool holder is mounted for pivotal movement and is spring loaded to the standby position such that work reaction forces deflect the tool and holder resulting in a relocation of the lever coupling to the counterweight unit. The ratio of the length of the lever arm varies to change the stroke of the counterweight and the counterbalance forces.

Abstract: Crimping press comprises an anvil and a die which is movable towards and away from the anvil. The anvil is moved by a rotating shaft having a crank-type coupling to the die. The shaft is capable of limited movement in the direction of movement of the die towards the anvil.
