Title: Rolling method for contraction of metal pipe
Inventor: NAGASE YUTAKA
IPC: B21B19/06
Filed: 1989-08-10
Abstract: PURPOSE:To constrain the generation of an angular shape with the eccentricity of the shaft center of a metal pipe to a mill center being restrained, by inserting an inner face regulating tool to the inside of a metal pipe and performing the contraction rolling of the metal pipe without performing a thickness reducing work. CONSTITUTION:A metal pipe 4 in whose internal part a plug 3 is inserted is decentered in one direction between rolls 1, 1 from the mill center C located on a pass line and a projecting part 4a is thus formed between the rolls 1, 1. In the 1st contact part 4b and 2nd contact part 4c of the metal pipe 4 abutting on the rolls 1, 1 formed with the projecting part 4a, a compressive force by the rolls 1, 1 and the plug 3 respectively is acted on the thickness direction of the metal pipe 4. At the projection opposed part 4d of the metal pipe 4 of the opposite side of the projecting part 4a, the plug 3 gives pressing force to the internal face of the projection opposed part 4d. This pressing force is to resist the force that the metal pipe 4 is going to decenter, the excessive projection of the projecting part 4a of the metal pipe 4, i.e., the buckling is thus constrained and the generation of the angularity of the metal pipe 4 can be restrained.
