Information

General Information - Hydro-mechanical Spring clamping cylinders are working with interaction of mechanical and hydraulic systems. The clamping force is applied through preloaded disk spring. The cylinders are loaded with spring clamping force, the hydraulic pressure is required only for the release of the spring force for the movement for the piston. This system guarantees the reliability because the clamping force is maintained fully independent of the oil pressure or leakage losses. Due to the short operating time the hydraulic system is cost effective. The clamping cylinders provide sturdy and reliable clamping system, that can be used where the sliding or movable machine parts need to be clamped or locked temporarily. Other applications are fixtures for work piece or tool clamping.


Assembly and adjustment - To operate a hydraulic unit is needed which should be equipped with a manometer, a pressure cut-off valve, a solenoid valve and a pressure switch unit fill the cylinders and lines at low pressure and to increase system pressure to achieve required pressure, align cylinder position using the ring guide nut, setscrews until the thrust piston or the clamp is free from play, fasten thrust piston with screws or secure the ring guide nut on the clamping cylinder release system pressure; set release pressure for the required release stroke; check the release stroke and adjust if necessary


Working principle / specification

Operational principle - The piston thrust is developed by the disk spring stack. The spring stack is compressed with increasing oil pressure the spring force increases. Under pressure, the corresponding nominal clamping force is reached as a reaction force of the disk spring stack. To release the thrust, a higher hydraulic pressure is required, which, up to a maximum value, is proportional to the release stroke. The setting pressure is required only for precise force adjustment during initial installation. During the actual operating cycle, the cylinders are at release pressure.
