Abstract

PURPOSE: To prevent the sound of shock generated from mutually hitting constituent members of the die from being leaked to outside of the die, by providing a sound insulating member in at least one of constituent members of the die, and by enclosing the space formed by this constituent member and another constituent member of the die with the said sound insulating member.
CONSTITUTION: An elastic member 8 is firmly stuck to the working plane of the die 2 in its entire circumference outside of the blank sheet to be worked. On the other hand, a goove 8a is cut in the blank holder 5 in such a depth as possible to sufficiently press the elastic member 8 to the blank holder 5 when the blank holder 5 goes to touch the die 2. A blank sheet is laid upon the blank holder 5 and is set in the prescribed position. As the die 2 is brought down, the elastic member 8 first touches the blank holder 5. At this point, the space formed by the die 2, the punch 1 and the blank holder 5 is enclosed by the elastic member 8. The die 2 next touches the blank holder 5 and the work A is formed. By the present constitution, the sound of shock leaks hardly to outside of the press die.
