Title:
PIPE BENDING DEVICE WITH ASSIST FUNCTION AND BENDING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/055408
Kind Code:
A1
Abstract:
Disclosed are a pipe bending device and bending method, which are capable of executing the bending method of any of a pressing force applying system, a tensile resistance force applying system, and a no-load tracking system.
Specifically disclosed is a pipe bending device (1) which is configured by a bending die (2) for winding a pipe (9) around the outer peripheral surface thereof to perform bending, a chuck (7) configured in such a manner as to grip a rear end section (9d) of the pipe, a feed positioning device (8) configured in such a manner as to allow movement in the axial direction of the rear end side section of the pipe (9) that holds the chuck (7) and is gripped by the chuck (7), a feed servo motor, a bending servo motor for supplying rotational driving force to the bending die (2), a ball screw (5) configured in such a manner as to be able to move the feed positioning device (8) and the chuck (7) in a predetermined direction by converting the output torque of the feed servo motor into the thrust of a slider (5b), and a control device for controlling the output torque of the feed servo motor.
