Extra-safe wedge clamp for presses

Roemheld’s range of die-clamping solutions for presses and injection-moulding systems has been supplemented with a newly designed series of robust wedge clamping elements.

A hydraulic model has been developed specifically for the fixing of upper dies that meets the highest safety requirements.
An additional locking cylinder holds the wedge clamping bolt in position and prevents any inadvertent retraction. Release of the clamping device is only possible once the locking mechanism has been opened, which ensures that the upper die is retained in position, even in the event of a pressure drop.
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.
Due to the Roemheld wedge clamps being 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, while the maximum operating pressure is 350 bar.
When elements are to be used for processes with high heat requirements, special designs are 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 1250 kN, and even higher retention forces.
