Abstract
PURPOSE: To prevent occurrences of deformation and scratch in products so that stable forced lubricating drawing is performed, by specifying clearance between the plug and pipe material and between pipe material and the inlet tube.
CONSTITUTION: When a pipe material B is drawn through a ring-shaped space formed by a die 10 and a plug 14, a forced lubricating drawing is performed by setting a clearance C1 between the plug 14 and the pipe material B and another clearance C2 between the pipe material B and an inlet tube 12 in the following way: C1≥(H-t)/4, C2≥(H-t)/8, where H is a clearance between the plug 14 and the inlet tube 12 and (t) is the thickness of the pipe material B. In this way, the internal pressure and the external pressure on the pipe material B are regulated to the same and deformation of pipe material B before the pipe material B is put into the die 10 is prevented, and then, the force required for the drawing becomes smaller when compared with conventional lubricating drawing.
