摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an L-shaped nut-bolt turning tool capable of reinforcing a head portion by a ring-like member.
SOLUTION: The method for manufacturing the L-shaped nut-bolt turning tool includes: a cutting step for obtaining a stock 1 with a specified length by cutting a long steel pipe; an adhesion step for disposing the ring-like member R with an inner diameter larger than the outer diameter of the stock at the outer circumference of the tip of the stock and inserting a male die 20 for pipe expansion to the inner wall of the tip of the stock and expanding the tip of the stock to stick the ring-like member R to the tip of the stock after the cutting step; a hexagonal bore forming step for inserting a male die with a hexagonal bore to the inner wall of the tip of the stock to form the hexagonal bore at the inner wall of the tip of the stock after the adhesion step; and an L type processing step for bending the stock into an L shape at a predetermined position after the hexagonal bore forming step.
