Abstract

PURPOSE: To work a nozzle to a desired size and to improve productivity by determining the outside diameter and wall thickness of a blank pipe corresponding to the inside and outside diameters of the desired nozzle and swaging the pipe.
CONSTITUTION: The outside diameter D01 and wall thickness (t) corresponding to the inside and outside diameters Di2, D02 of a required nozzle are determined, and a mandrel 17 of an outside diameter smaller by about 5W20μm than the inside diameter Di2 of the nozzle is inserted into the pipe 15. Thence, one end of the pipe 15 is grasped by means of a pair of split dies 16, 16, and the dies are rotated and driven in the circumferential direction of the pipe 15 and are displaced in the diametral direction, whereby the outside circumferential surface of the pipe 15 is hammered and swaged to the desired inside and outside diameters Di2, D02 of the nozzle. Also, the mandrel 17 is hammered together with the pipe 15, whereby it is worked to the nozzle of highly accurate roundness and inside surface roughness.
