Slide Lock System


Area of application

The Optima slide lock system type OSV is used for rendering the slide safe when working in the die space or on the machine itself. It is mainly used for mechanical, but also for hydraulic presses.

Rigidly installed, suspended in the press crown area, its use requires a slide which has externally welded-on contour plates, or cut-outs in the slide.

Mode of operation

By means of an electric motor and a gearbox, a threaded nut is set in rotation. The nut, in cooperation with the associated spindle, initiates the necessary rotary movement. The tie rod, which is in the parked position (fully extended), first performs a 90° rotation, and then moves directly to the slide and prevents it from being lowered accidentally.

A hydraulic cushion ensures release of the tie rod, even under load (within the possible release distance). Sticking of the tie rod is thus virtually impossible.

Movement sequence for securing the slide:

Distinguishing features

Due to the continuous variation in length of the tie rod, the press slide can be locked in any position. The single-motor construction ensures simple electrical installation and compact external dimensions.

Electrical control of the following functions (switches):
