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.
