The new arch clamp is 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.

An integrated mechanical lock reliably holds the upper die in position in case of a pressure loss. Thus, it cannot fall. The die clamping element does not corrode even under the harshest conditions, thanks to a special coating process. 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 provide 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 additional equipment is integrated on the side of the clamping bolt to safe space. It provides information on whether the bolt clamps or unclamps the die and whether the clamping position is overrun.

The clamping element is named after the arch-shaped clamping bolt with which the die is clamped.
