ABSTRACT:
Forging equipment and techniques prevent damage to the die set while also preventing abnormal flow of the material used in the forging process. In one embodiment, the forging equipment comprises a die set with a holding portion, constructed separate from the guiding portion. The holding portion is configured to accommodate the workpiece material and the punch portion as it is dropped down on the workpiece. At the comer where the holding portion and the guiding portion meet, the holding portion forms a retaining cavity, which has a sufficient size to accommodate a metal sealing assembly. The metal sealing assembly at one end terminates in an angled material contacting surface that prevents formation of cracks and abnormal flow of material away from its intended path of flow.
