Market leader for die clamping technology expands its range of wedge clamps 


The new arch clamp is designed to be exceptionally sturdy and safe for use on presses and forges. The clamping technology specialist ROEMHELD expands its multi-member wedge clamp family with this clamp. The clamping element is named after the arch-shaped clamping bolt with which the die is clamped.


An integrated mechanical lock reliably holds the upper die in position in case of a pressure loss, preventing it from failing. The die clamping element is coated to prevent corrosion even under the harshest conditions. The arch-shaped force curve of the clamping bolt virtually eliminates jamming at the clamping point. 


Double-acting and with position monitoring on request 


The double-acting arch clamp is designed for versatile use with straight clamping edges. The clamp is suitable for high clamping edge tolerances of ±1 mm. Clamping and unclamping pressure of 200<bar are identical and supply a maximum clamping force between 30 and 450 kN and process forces up to even 620 kN. 


There are also variants with and without position monitoring for particularly high process reliability. The added equipment is integrated on the side of the clamping bolt to save space. It provides information on whether the bolt clamps or unclamps the die and whether the clamping position is overrun.
