Inventor: NAGASE KENZO
IPC: B21D51/16
Filed: 1995-06-05
Abstract: PURPOSE: To obtain a locking end part forming material for steel tube connection of light weight and low cost and capable of coping with small demand and its forming method by imparting a taper inside face, thickening the inside diameter of outside face. CONSTITUTION: A standard long size steel tube stock of mass production is cut to ring material to use for a stock.
