Abstract
PURPOSE: To close the open end of the metallic pipe without causing the extraordinary abrasion, deformation, and cracks, in the working metal for use of the deep drawing, by executing the deep drawing work while above working metal is forced to make the linear reciprocating motion, facing against the open end of the rotating metallic pipe to be worked.
CONSTITUTION: The metallic pipe with closed end is manufactured by executing the deep drawing work on the open end of metallic pipe. Hereupon, the deep drawing work is executed by the flat plate type super hard steel made working metal 2 for use of the deep drawing work, while it is forced to make the linear reciprocating motion so as to contact against the opne end 1 of the metallic pipe to be worked being always rotated through the period of working; in which, the contact is made loosely in the tangential direction and uniformly over a specified length. Moreover, the pressure welding of the working metal 2 for deep drawing, and the linear reciprocating motion are executed by the apparatus connected to the holder 3 made of hard steel or semi hard steel. According to this method, the extraordinary abrasion, deformation, and cracks, of the working metal 2 are perfectly prevented, and its working life and the interval of renewal are extended. At the same time, the metalic pipe with the closed end and constant shape and size can be easily manufactured.
