Abstract

PURPOSE:The thread rolling machine with simple construction, in which a link is put across the eccentric positions leaving the same distance from the axial center of the thread rolling roller, and the revolution of all rollers are interlocked. CONSTITUTION:Two heads 8 are placed in a distance, and the material (a) to be thread rolled is inserted and positioned among all rollers 15. Pressure oil is supplied so as to extend the piston, and the head 8 on the piston side is brought near to another head 8, and the male screw of all rollers 15 is contacted against the thread rolled material (a). The sutomatic interlocking mechanism is formed by installing a board 26 which has monolithically the link 26a being put across the axial center of adjoining roller in the circumferential direcftion of this thread rolling roller in the circumferential direction of this thread rolling roller 15; hereby, the center of all rollers 15 coincides with the axial center of the thread rolled material (a). Next, the chuck is driven so as to force the material (a) to rotate accompanying the rotation of the roller 15 that is contacting with the material (a); hereby, the smoothly continuous screw is plastically formed in the outer surface of the thread rolled material (a).
