Abstract
PURPOSE: To prevent diestem core from deformation and damage by securely holding diestem selectively by correspondingly moving intermediate frame having guide ring holding the outside perimeter of diestem in the direction of press.
CONSTITUTION: The billet A and the press plate 21 are first put in the container 17, then pressure stem 20 is set forward by a forwarding force, and then the tip of the mandrel 22 is made to fit in the die hole. In this state, the pressure stem 20 is put forward by a press force, and at the same time the container is put forward, whereupon hollow products are obtained. At this time, the diestem 4 is burdend with load, but the root of the diestem 4 is strongly supported by the press platen 1. And, the tip of the stem 4 is supported by the guide ring 11 of the intermediate frame 10. Thus, the accuracy of the diestem 4 can be held bacause it can withstand the pressing force to a great extent
