Abstract

PURPOSE: To well deep draw a tapered double skin, by forming opposed surfaces of a pair of punches into plane surfaces, and forming the other surfaces into tapered surfaces for inscation, in order to make the material flow smooth.
CONSTITUTION: A blank 7 made inclined downward is clamped between a die 1 and a blank holder 6. When the punches 5a, 5b are pushed into the die 1, as a tapered surface of the opposite side to a vertical surface along the drawing direction of the punch, is inclined to the wall of the die 1, so that bending angle of the blank at the points A, B become easy and the frictional resistance is reduced. Accordingly, the material flow to the central wall part C is made smooth and the occurrence of breakage of the blank at the D part is made hard. As the blank at the central wall part C is held between the surfaces of the lower part of the punches 5a, 5b along the pushing direction and the wall surface of a partition 2, the wrinkling is prevented. After the drawing, a folded part at the center of the product is reformed in the following process.
