Abstract

PURPOSE: To obtain draw products having desired inclind angles by one time of pressure forming work, by making an arrangement so that each of the draw ring and pressure ring are freely slidably in response to the intrusion of punch.
CONSTITUTION: After a metallic plate 9 is placed on the upper surface of a draw ring 5, a pressure holder containing a pressure ring 7 is lowered. The plate 9 held by rings 5 and 7 is draw formed successively by the descending movement of a punch 4. At this time, since sliding rings 72 and 52 which are set under freely slidably, respectively, out of the rings 7 and 5 move backward in accordance with the intruded length of an inclined wall 41 and no clearance is generated between the receiving port of these rings and the punch, beautifully formed tureen-shaped bodies which coincide with the outer shape of punch, are obtained. Moreover, pushing back cylinders 6 and 8 are provided to rings 52 and 72.
