Abstract
PURPOSE:To form a heating and fixing roller in one body with high strength, by forming the shaft inner diameter into accurate size with a simple processing without boring process, through reduced drawing with a metallic pipe extruded in a die open hole the tip of which is formed in bell mouth. CONSTITUTION:A mandrel 14 having equal outer diameter to the inner diameter of a shaft 13 of a heating and fixing roll 12 is fixed to a die holder 11 having channel shaped cross section, and a die 15 is inserted to the die holder 11 concentrically with the mandrel 14. The tip of molding open hole of the die 15 has a bell mouth 16, and parts other than the tip have parallel gap 17 with the mandrel 14. When a metallic pipe used for the roll 12 is extruded in the open hole of the die by coinciding the shaft center, the pipe is extruded into a shape having a slope 18 of cone shape and a shaft 13, through reduced drawing along the bell mouth 16. As required, the reduced drawing is made again and the slope 18 can be drawn vertically to the shaft.
