Abstract
PURPOSE: To prevent a valve bar from sliding and being twisted off, by not only making it possible to freely rotate the plane roller but also making oiling holes in the shaft cores of both the rollers, in case of performing thread rolling working of the valve bar with the thread roller and the plane roller of the thread rolling machine.
CONSTITUTION: The fixed shaft 1 and the movable shaft 2 of the thread rolling machine are rotated in the same direction, and at the same time the movable shaft 2 is made movable in the direction of P. The thread part A' of the valve bar A and the shaft part A" are placed between the thread rollers 8, 8, and the plane rollers 14, 14, respectively, and reformation of the thread part A' of the valve bar A, and burnishing of the shaft part A" are carried out at the same time with both the rollers 8, 8, and 14, 14. In this case, when pressure in the twisting direction is put to the shaft A", both the plane rollers 14 do not go against the twisting pressure but shun it of themselves, by free rotation owing to the bearing metal and the bearing 11. At the same time, it is prevented that foreign matter enters between the thread roller 8 and the plane roller 14 through the lubricating pipe 19 and the lubricating holes 15, 16 by the operation of the hydraulic pressure pump, smooth rotation can be performed, and it is not caused that the valve bar slides, jumps out or is twisted off.
