Abstract
DE 4130004 A UPAB: 19930924 The press has a ram which is driven from two parallel crankshafts through interconnected links. The mechanism is driven through either of two input shafts. On the working stroke the driving shaft (7) is connected to the driving gear train through the clutch (28) so that the pinion (6) drives the gears. On the return stroke the clutch (28) is disconnected and the drive is transmitted through the clutch (4) and the shaft (1) which has a driving pinion (2) which has a larger diameter than the driving pinion (6) of the shaft (7). USE/ADVANTAGE - Metal forming press with high speed return stroke which reduces the press cycle time.
