Abstract
PURPOSE:To prevent a panel from deformation in press working, by providing a surface of a work supporter being placed out of the lifting path of said supporter which is moving vertically by a lifter. CONSTITUTION:A work supporter 15 is provided to the position where a work W is supported, at the time of setting the work W to a lower die holder 8. The supporter 15, equipped with many holes 15a and a work supporting surface 15b, is arranged in the inside of a lower die 9; many rubber rollers 10 of a work supporting part of a lifter 11, being incorporated into the holder 8, move up and down through the holes 15a. In a state that the lifter 11 is lifted, the work W, of which an outer panel 2 is lapped on an inner panel 3, is fed onto the rollers 10, situating at the upper side of the holder 8 and; then the work W is set on the supporter 15 and the die 9 by moving the lifter 11 downward. Next, pre-hemming work is performed by an upper die; at this time, the deformation of the work W doesn't occur because the main parts of outer panel 2 are supported by the die 9 and supporter 15.
