Abstract

PURPOSE: To prevent the break of lubricating film during the drawing work, and to prevent the seizure, etc., by installing two or more throats in front and behind the die, and by making the gap formed between the inside surface of the pipe and the outside surface of the plug to be the lubricant pool.
CONSTITUTION: The plug 6 comprises the taper part (zone A) and the parallel part (zones B, C); the outside diameter of the parallel zone C is specified a little smaller than that of the zone B. With this plug, the throat 5 of the first die 7 mainly draws the outside diameter of the pipe 1, and the throat 5 of the second die 8 mainly draws the wall thickness. Then, when the pipe 1 is to be drawn, the liquid lubricant is sent into the clearance 4 between the pipe 1 and the plug 6; hereupon, since the contact pressure between the pipe 1 and the zone B at the throat 5 of the second die 7 is comparatively small, the sufficient lubricant is pulled in, and the lubricant pool 9 is formed in the clearance between the inside surface of the pipe 1 and the outside surface of the zone D of the plug 6.
