Wedge Clamps for Tapered Clamping Edge

without and with position monitoring at the side 

Double-acting wedge clamp for clamping moulds or dies on a press bed or ram or in 
injection moulding machines, machines and installations. The wedge clamp consists of a hydraulic block cylinder and a piston guided in a housing. The clamping bolt is provided with 20° bevel to clamp on the tapered clamping surface of the die. Based on the internal design of the wedge clamp and the 20° bevel of the clamping bolt, the system is providing internal friction. For safety reasons and in the sense of the machine tool guide lines 89/37/EC the hydraulic pressure must be maintained. When upper dies are clamped by wedge clamps, they must be secured mechanically when maintenance work is carried out.

The proximity switches are installed in the guide housing. They are activated by means of the wedge bolt. The positions bolt in off position or in clamping position are displayed. 
Temperature resistance: up to 100 °C (with position monitoring)
cable length: 250 mm
connector: 4 pole
