In the field of mechanical and hydromechanical clamping elements, Enemac, Kleinwallstadt, Germany, offers various power clamping systems and hydromechanical spring clamping systems.
The range runs from the controlled clamping with torque handle ESBS/ESBT with a nominal clamping force of up to 40 kN towards power clamping nut ESB with up to 200 kN and the type ESD with up to 180 kN. For these products, relatively low torques are converted by an internal gear ratio in high axial forces. In case of the power clamping screw ESS the tightening torque is converted by a wedge clamping system in clamping forces up to 250 kN. Therefor available are thread sizes from M 36 to TR 100.
With the so-called spring clamping cylinders, a combination of disc spring and hydraulic, clamping forces up to 350 KN are available. The hydraulic supply has to be present only during installation and removal of these products, in operation, the axial force is kept purely mechanically by a disc spring assembly. This innovative clamping technology offers a real alternative to both simple work holding equipment such as clamps and brackets as well as to semi-and fully automatic clamping elements with their elaborate power supply and control systems.
Especially in the manufacturing process of steel parts in presses and punches the clamping elements provide a high degree of safety and humanization of workplaces through low hand forces during tightening of the necessary tools and equipment. Due to the left out installation costs, the minimum operating and maintenance costs, as well as the moderate purchase price those clamping systems often represent the most economical solution and are suitable both for original equipment of machines also as a retrofit item.
