Abstract

DC60 (10/03/40) Pipe bending system for bending various pipes in a style. Effectively pre-set by detecting pipe bending angle Changing During the bending process In a manner with high fidelity By the checker knows The movement And by comparing the detected values of degrees in Bending a pipe detected by a motion detector with written controls. Advance in the program in memory The motion detection sensor is positioned. In order to be able to detect the position of the pipe to be bent on the side of the section. Receive reaction between gripping devices And reaction part Motion sensor It consists of a detector and a converter that indicates where the pipe will be. Bending detected by the sensing part. It is converted to bending degrees to the pipe to be bent. The transformed part and the converted bending angle are passed to the controller. During a new pipe repeat operation So that the degree of bending is closer to the degree In a preset bending Pipe bending system for bending various pipes in a preset manner, effectively starting work by detecting the bending value. Changing During the bending process In a manner with high fidelity By the checker knows The movement And by comparing the detected values of degrees in Bending a pipe detected by a motion detector with written controls. Advance in the program in memory The motion detection sensor is positioned. In order to be able to detect the position of the pipe to be bent on the side of the section. Receive reaction between gripping devices And reaction part Motion sensor It is equipped with a detector and a conversion element indicating the position of the pipe to be Bending detected by the sensing part. It is converted to bending degrees to the pipe to be bent. The transformed part and the converted bending angle are passed to the controller. During a new pipe repeat operation So that the degree of bending is closer to the degree In a preset bending

Claims (4)
