Abstract

PURPOSE: To press the work of a convex curved surface to a die and reverse drawing the same in one process by means of a punch, by providing a punch ring to the circumference on the punch side at the time of reverse drawing said work.
CONSTITUTION: First, a punch holder 17 is moved upward to detach an insert pad 28 and a punch ring 29 from a die 4. Next, the work W is placed on knock-out pins 13, 14 in such a way that its convex curved face side opposes to a punch 20. Thence, when the punch holder 17 is lowered, the insert pad 28 and punch ring 29 contact the convex curved face side of the work W and position the same. When it is lowered further, a spank rod 22 presses the rod 7 which in turn lowers a cushion pad 6, causing the knock-out pins 13, 14 to descend from the surface of the die 4. Following to which, a spring 26 springs a pad base 25 downward and the insert pad 28 grasps the work W between the same and the die 4. Thence, the punch ring 29 deforms the work W to the surface shape of the die 4 by the elastic force of a spring 33; at the same time, the work W is pulled downward by the descending of a punch 20, whereby drawing is accomplished.
