Abstract
PURPOSE: To join a pipe and a shaft together so as to align surely on the same axis by fastening a pipe, with which a shaft is internally aligned so as to be concentric, to the shaft while shaping by continuous beats with dies rotating relatively to the pipe.
CONSTITUTION: In joining a pipe P to a shaft S with a considerably smaller diameter than the internal diameter of the pipe, a pipe end is inserted from one side into dies 8 opened to the maximum diameter, and the pipe end and the center axis of dies are aligned and fixed so as to be concentric with each other. The end with grooves G of the shaft S and the pipe are aligned and fixed to the inside of the pipe end in the same way. then, a spindle 7 is rotated while a tapered pile 10 is inserted, the pipe end being continuously beated at the same time in the four directions to contract the pipe in diameter. In this final stage of swaging, the dies 8 come in contact with each neighbour and stop the positioning action for the pipe to become a circular cross section, resulting in a complete circle of the pipe external shape. And, no useless raise on the pipe external surface is produced due to the gaps between the dies, enabling to join surely the pipe to the shaft on a concentric axis.
