Abstract

PURPOSE: To make possible the rapid and sure positioning of blank end by providing a hole to the inside wall of a stationary die of upset-forging dies and inserting a slidable stopper and reset spring in the hole.
CONSTITUTION: A long-length tubular blank 20 is inserted along the inside wall of a stationary die 1 until its end 20' abuts against a stopper 12, thence it is fixed. A moving die 2 is pressure-contacted to the stationary die 1 to sandwich the blank and a punch 3 is entered into the die to apply forging to the blank end. At this time, the stopper is pushed by the action of a tapered surface 12' and retreats in the hole 11 against the elastic force of a spring 13, but along with the withdrawal of the punch upon ending of forging, it resets to the original position.
