Document Type and Number:
WIPO Patent Application WO/2011/162375
Kind Code:
A1
Abstract:
The disclosed tube machining device (10) is provided with: two chucks (11, 12) that respectively hold a first and second holding position (H1, H2) in a manner so as to sandwich a heated section (S) therebetween resulting from a pipe (P) heating coil (14); and a mandrel (13) that contacts the pipe (P) between the holding positions (H1, H2) and supports the pipe (P). Also, using conveyance devices (15, 16), the distance between the holding positions (H1, H2) is reduced, and compression force is applied to the pipe (P) in the axial direction therebetween.
