Principles of Forging Presses,e largest ingot and its material characteristics at forging temperature. Usually, the overall dimensions and the weight of the ingot are indicated by its cross-section (see table 1). The ingot cross-section must be determined by the largest forging to be made by the press where, depending on the req

Controls for Forging Presses,trol slide valves, their drive, and the equipment for the proper successive valve movements. The control gear determines the working stroke of the press by the opening and closing of the poppet or slide valves which control the feed and return of the cylinder’s fluid. It consists of the main control

Economy and Comparison of the Various Kinds of Drive for Forging Presses,l pressure without utilizing the expansion energy. Particularly prodigal is the steam operation for planishing, when the controls are reversed for constant pressure (p. 179) in order to attain more strokes per minute. In this case there is no difference between idle and working strokes of same size,
