Title:
TUBE BENDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/173048
Kind Code:
A1
Abstract:
This tube bending system bends, into a predetermined shape, a to-be-processed tube including a metal tube and two flare nuts, and comprises a bending machine and a tube feeder. The tube feeder comprises: an edge alignment mechanism that performs, on the to-be-processed tube, an edge alignment operation for moving the two flare nuts toward one end of the to-be-processed tube so that one of the two flare nuts collides with one of the two annular protrusions and the other one of the two flare nuts collides with the other one of the two annular protrusions; and an inspection mechanism that uses the edge alignment operation to detect abnormalities in the to-be-processed tube to be bent by the bending machine.
