Abstract
A device is provided comprising a guide mechanism used to position and securely hold a sheet metal blank in a sheet metal forming press that is operated at high temperatures. A sheet metal blank is initially positioned in the forming press by resting the sheet metal blank on the highest portion of the convex surface of the lower tool member and counter balancing it with a blank loading device that includes a support hand to initially hold the blank. The guide apparatus comprises an engagement tool mounted to a beam that is slidably attached to guide supports. As the upper tool member drops, the engagement tool pinches and securely holds the sheet metal blank as the guide supports slide along the beam in sync with the downward movement of the upper tool member.
