The wedge clamping element itself comprises a block cylinder with housing-guided clamping bolt. An angled contact surface creates a frictional connection in conjunction with angled die clamping edges. A position control is integrated as a space-saving measure to monitor the clamping and release position, as well as the status of the locking mechanism. Whenever there is no die available, a notification is issued.
As the Roemheld wedge clamps are constructed as a variant system, they can be adjusted in accordance with respective customer requirements. The standard range already includes seven designs with clamping forces of 25 to 630 kN, and cylinder dimensions of between 25 and 125 mm. Clamping strokes of 15 to 36 mm are available here, and the maximum operating pressure is 350 bar.
If the elements are to be used for processes with high heat requirements, special designs are also available which are temperature-resistant up to 300°C. In addition, there are versions for straight clamping edges, as well as models with clamping forces of up to 1,250 kN, and even higher retention forces. Further options include special permanent lubrication, and multi-layer coatings for the clamping bolt and housing that have a positive influence on wear properties.
As existing dies can often be re-tooled for wedge clamping with the introduction of wedge bars, the elements are also suitable for retrofitting.
