ROEMHELD: New wedge clamping element with patented safety bolts for angled clamping edges
A new wedge clamper featuring dual functionality and extensive safety functions has joined the range of clamping technology products from the ROEMHELD Group for presses and punches. The innovation boasts a patented bolt with positive-locking safety step, which can safely hold even heavy upper dies during pressure drops or maintenance work on the die.
A new wedge clamper featuring dual functionality and extensive safety functions has joined the range of clamping technology products from the ROEMHELD Group for presses and punches. The innovation boasts a patented bolt with positive-locking safety step, which can safely hold even heavy upper dies during pressure drops or maintenance work on the die.
The combination of automatic movements, position control of the clamping bolt and the built-in safety step is the hallmark of this reliable, easy-to-monitor clamping die. It can be used, for example, on the pressing tappet with angled clamping edges. The wedge clamp, thanks to its robust design, is able to withstand high temperatures and soiling and offers a long service life. The modular design guarantees cost-effective production, high parts availability and short delivery times.
Positive-locking safety step secures upper dies during a pressure drop
The wedge clamp is made up of a hydraulic block cylinder and a housing-guided bolt with a contact surface angled by 20°. A step in the form of a “lug” on the clamping bolt and a corresponding adapter on the die clamping edge provide additional safety.
If there is a drop in pressure at the pressing tappet for any reason, the upper die descends onto the safety step and, with the adapter, forms a positive-locking connection that secures the screws and die in place. A position control also checks the clamping and releasing position of the bolt and also reports if no die has been placed or the clamping edge is not set correctly.

Simple retrofitting thanks to flexible, adjustable clamping materials and corresponding adapters
ROEMHELD is making retrofitting easier with adapter plates that can be simply attached to existing dies. The wedge clamp elements are also designed as a variant system, allowing customers to choose from a range of design options. Elements with a single or dual function, exerting clamping forces from 25 to 1250 kN, are available for straight and angled clamping edges. The wedge clamps can also be used virtually maintenance-free thanks to permanent lubrication. Multi-layer, high-tech coatings can also be applied on request to the bolts and housing in order to reduce wear and tear during challenging applications.
