Abstract
PURPOSE: To simplify construction and increase blank holding pressure by fixing the bearing body of the blank holding mechanism to the frame and fitting a retainer which performs specified operation by engaging to the blank holding plate to the ram.
CONSTITUTION: Prior to starting of the work, a control valve 21 is beforehand so adjusted that specified blank holding pressure may be given by the pressure in a cylinder 18. Next, when a thin plate material A is inserted in the clearance between a die 14 and a blank holding plate 13 and a punch 11 is lowered, the material is applied with pressing force by the pressure in the cylinder 18 by way of a piston 17 and pressure pin 16 and at the same time, the blank holding plate 13 descends at the same speed as that of the punch 11 while being supported by a retainer 12 until its bottom face contacts thin plate material A. Further when the descending of the punch 11 continues, the engagement between the retainer 12 and the blank holding plate 13 is released and the blank holding plate holds down the thin plate material A under the preset constant load. When the punch 11 descends further, drawing is accomplished.
