Abstract
PURPOSE: To make possible titled plastic working of wire and bar materials without increasing roll diameter by forcibly passing a wire material of predetermined length into the holes dies of a pair of roll of the same diameter which are formed with continuously changing spiral grooves on the circumference and are reversible of phases.
CONSTITUTION: A pair of rolls 3, 3' of the same diameter which are formed with spiral grooves 7 of continuously changing sectional shapes, surface shapes or both shapes simultaneously, symmetrically on the circumferential surface, are in contact with each other in parallel, and of which the spiral grooves 7 maintain symmetry, are mounted to a frame body 6, and mutually meshing timing gears 9, 10 of the same module are provided. The are made mutually reversible by means of shafts 31, 31', whereby the device is constituted. The spiral grooves are so formed that a wire or bar material becomes of a circular or various shapes in sectional shape or shallow plastic working is applied on the front layer of said sections when it is passed in the hole die 11 continuously formed in the above-mentioned contact lines by various predetermined force means. With this method, the plastic working of a long-sized wire or bar material of about several W several tens times the peripheral length of the rolls becomes possible.
