Abstract

PURPOSE: The titled press made possible to form with good workability without generating the cutting loss, by first forming into the open mouthed square shape in the press, and successively, by correctly press forming the insufficiently bent corner part.
CONSTITUTION: The steel sheet (f) is set at the specified position, and the pressure medium is supplied simultaneously to the inner cylinder 6 and the outer cylinder 16 both being at the upper limit position, to descend the central part forming punch 9 and the both side forming punches 19 in order to carry out the preliminary forming work for both sides. Next, after elevating the both side punches 19, the central part forming punch 9 is descended to bend the central part of the steel sheet (f) between the central part forming die 23. Next, after disconnecting the inner slide and elevating it to the specified position, the corner forming punch 15 is descended, and the bending work for both sides of the steel sheet (f) is carried out while the side plane of the corner forming punch 15 is restraining the escape of the steel sheet (f). Next, the forming punch 15 and the cushion pad 25 are elevated to push out the formed square steel pipe.
