Abstract

PURPOSE: To improve the accuracy of shape size by using the units set with small size rollers in housings and a sizing ring.
CONSTITUTION: When the long-sized pipe work 4 inserted with an inside mandrel 5 is pushed in the arrow direction, it is drawn by the forming rollers 1 placed in the axial direction of the inside circumferential face of the housing, but the portions 10 between the rollers are not worked. These portions are drawn by the rollers 2 placed with circumferential deviation from the rollers 1. Further the long-sized pipe advances and passes the inside of the sizing ring 6 at the unit outlet, whereby the predetermined shape and size are assured. It is also possible to form the pipe by placing two or more stages of the units according to the change in the shape to be given to the work.
