Application of Dual-hanger Clamp Feeding Mode to Full-auto Pipe Cutting Machine

Described here in the paper is a feeding mode controlled by a dual-hanger clamp device for the full-auto pipe cutting machine,involving such aspects as the structure of the full-auto pipe cutting machine proper,the working principle and the control program,etc.Precisely feeding of the tube into the cutting machine is realized by the servocontrolled double-hanger clamp feeding system together with the inner clamping device as mounted in the headstock.And the initial tube plain-end cutting position can be accurately located,and the actual length of the tube measured through the laser induction switch as attached on the hanger clamp device.Owing to the PLC calculation and control,the remained pipe section after cutting is reasonably distributed for cutting,and the tube tail section is properly processed.Thanks to application of the dual-hanger clamp feeding mode to the full-auto tube-cutting machine,it is realized to precisely feed the tube for cutting,and optimally process the remained section and tail section of the tube as cut.
