Technical data

Knee lever die cutter with pneumatical support

The pneumatic supported specimen die cutter PSTA.01 is a knee lever unit with a very smooth running ball bearing linear guide. It serves to produce specimens made of rubber, elastomer or plastic. The operating force is independent of the required punching force (maximum 2.2 tons)

This system is characterized by a finely adjustable punching shear position affecting the cutting die. Furthermore it has a forced eject system at its rearmost end.

Technical drawing

The basis of the unit consists of a cast steel frame (1). By a fast-clamping system of a fine adjustment (2) it is possible to adjust the punching shear position precisely. After processing the specimen it is automatically released by the ejector (4).

As a counter bearing during processing serves a flat support plate (3). The die support is made of cardboard (5 - see accessories) and serves - while a specimen is processed - as an exchangeable protective element for the cutting edge and also guarantees exact cutting results.

The knee lever die cutter is shown with a punching knife unit and clamping adapter.
