IPC: B21D7/06
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a method of bending a metallic pipe with relatively high accuracy of bending angle in a short time and at a low processing cost. SOLUTION: This metallic pipe bending method consists of a rough-bending process to form a bent portion 30 on a bent metallic pipe 3 with a pipe bender and a precision bending process to press-form the bent portion 30 of the metallic pipe 3 with mutually opposing an outer die 2 and an inner die 1. In the precision bending process, a pair of concave portions 33 are formed on the outside of both end portions 32 of the bent portion 30 by a pair of protruded portions 12 of the female die 1.
