Hydromechanical press molding method for sheet metal blank, involves supplying pressurized liquid between press and sheet metal blank so that blank can be completely molded by recess of die, after flange of press contacts die

摘要

The hydromechanical press molding method involves pressing a sheet metal blank (4) towards the recess (1.1) of a die (1) by using a press (2), until the flange (2.3) of the press contacts the die. Pressurized liquid is supplied between the press and the sheet metal blank so that the blank can be completely molded by the recess of the die, after the flange of the press contacts the die.
