Document Type and Number:
Japanese Patent JP7146191
Kind Code:
B2
Abstract:
To make a pipe contraction device compact as far as possible.SOLUTION: A pipe contraction device 10 includes: a mold 20; a pair of roller devices 30 pressing a metallic pipe in a diametrical direction of a center axis J; and a rotary device 50 that rotates each roller device 30 around the center axis J. Each roller device 30 has a block body 31 extending in a direction intersecting the center axis J, a first support shaft 32 that supports the block body 31 so as to rotate in the diametrical direction of the center axis J, a hydraulic cylinder 35 that applies force to the block body 31 so as to rotate about the first support shaft 32, a second support shaft 38 provided at a position between the first support shaft 32 and the hydraulic cylinder 35 on the block body 31, and at least one roller 40 that is supported through a coupling member 39 so as to rotate around the second support shaft 38, and pressed the metallic pipe.SELECTED DRAWING: Figure 2
