The wedge clamp consists of a hydraulic cylinder block and a bolt guided within the housing. As it clamps and the bolt advances, it mechanically locks the die in place.

New Wedge Clamp Offers Patented Safety Feature

Design includes notch to support the upper die in the event of a pressure loss.

An expanded line of Hilma wedge clamps for forging, from CARR LANE ROEMHELD MFG. CO., includes a clamp designed with a patented safety notch added to the tapered clamping bolt. The notch will support the upper die in the event of a pressure loss.

The wedge clamp consists of a hydraulic cylinder block and a bolt guided within the housing. As it clamps and the bolt advances, it mechanically locks the die in place with its 20° tapered clamp surface. In the unlikely case of a pressure loss, this new safety feature in the bolt will engage with a mating notch in the tapered clamping plate on the die set, securing the hold of the upper die.

During unclamping, the extended bolt retracts fully into the housing for easy die removal.

The wedge clamping elements, with single or dual action, exert forces of 3 to 69 US tons, and have a maximum temperature rating of 570°F.

The clamps can be actuated via hydraulic or electrical power, or spring loaded. Position sensors are available to verify the extended/clamped or retracted/unclamped positions.

Wedge clamps are available in a variety of styles allowing customers to configure clamping arrangements using a range of options from cooling circuits to sequence valve controls.
