Title:
MULTI-SUCCESSIVE TYPE PIPE BENDING DEVICE
Document Type and Number:
Japanese Patent JP3716949
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To improve twisting velocity, to efficiently execute the bending and the obtain the high precise and high efficient working by arranging plural bending devices side by side and bending from the end part while delivering a working pipe between each pipe bending devices.
SOLUTION: The working pipe P is supplied into the bending device 2 of a first line from a working pipe carrying device 4. On the side of No.1 bending unit 2a, a bending die is selected with a right and left positioning mechanism and a vertical positioning mechanism, and the working pipe P is clamped with a cylinder for clamping. Successively, a turning body is turned by a prescribed bending angle with a motor M1 for bending and the bending is applied from the endpart of the pipe P with a bending die, contracting die and pressing die. At the time of completing the working, the clamping at the No.1 bending unit 2a is released and at the same time, the pipe P is shifted to the following working position with an No.1 twisting unit 2b.
