Title: Square steel tube, its manufacturing method and equipment
Inventor: NAKAJIMA SHIN
IPC: B21C37/15
Filed: 2002-01-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a square steel tube having no projections on the outside of a beam-connecting part where thickness is increased.  <P>SOLUTION: A roughly formed square steel tube 5 (rough tube) is made by bend-forming and then butt-welding a steel plate 1. A desired place B of the rough tube 5 is heated and then a compression force in the longitudinal direction A is imparted to the heated place B, increasing thickness in a part of the material toward the inner face 5a. With the whole rough tube 5 heated which is formed with the increased thickness part 8, the square steel tube is obtained by performing hot forming in the manner that the dimension d between the outer faces 7b of the oppositely facing sides and the radius r of each corner become smaller than the dimension D and the radius R respectively of the rough tube 5 and that the outer face 5b becomes flat over the entire length. Thus, the square steel tube is formed with no projections on the outside of the beam-connecting part where the thickness is increased. In welding a beam to the square steel tube, the end face of the beam is acceptably a cut surface as is, dispensing with special machining.  <P>COPYRIGHT: (C)2003,JPO
