Abstract

PURPOSE: To surely hold the material, by installing the ironing protuberance intermittently arranged along the circumference of the die hole for holding material.
CONSTITUTION: The material holding die 9 possesses the die hole 14 aligned on the extension of the axis of the working hole 2 of the extrusion die 1. The die hole 14 has inner diameter a little larger than the maximum outer diameter of the material W. The material holding die 9 possesses plural ironing protuberances 15 intermittently arranged along the circumference of each of top and bottom ends of the die hole 14. The imaginary inner diameter D of the die hole 14, to be profiled by the ironing protuberances 15, is made about 0.02W0.05mm, for example, smaller than the maximum diameter of the material W. An end of the material W is inserted into the guide hole 13, and another end is fitted to the working die 1. When the working die 1 goes down, the material W is ironed by the ironing protuberance 15, and enters into the die hole 14, and is stopped at the bottom 6. Hereby, the material W is surely held.
