A pipe cutting detection device and method

Abstract

The invention relates to the field of pipe detection, in particular to a pipe cut-off detection device and method. The device comprises a first rotating portion, a moving assembly, a signal transmitter, a signal receiver and a processor; the first rotating portion clamps a pipe, the processor controls the moving assembly to drive the pipe to move on the first rotating portion to a cut-off detection position, then whether the pipe is obliquely cut or not is judged, if so, the processor controls the moving assembly to drive the pipe to retreat on the first rotating portion, if not, the processorcontrols the moving assembly to stop moving, the processor controls the first rotating portion to drive the pipe to rotate by 360 degrees, the processor controls the signal transmitter to continuously transmit sensing signals to the signal receiver in the rotating process, and if the signal receiver does not receive the sensing signals, an alarm signal is sent out. According to the device and themethod, firstly, whether the pipe is straightly cut or obliquely cut is distinguished, different cut-off detection is carried out according to the cutting type of the pipe, so that whether the pipe is correctly cut off or not is detected.

Description

technical field [0001] The invention relates to the field of pipe detection, in particular to a pipe cutting detection device and method. Background technique [0002] Due to its high quality, high flexibility, high efficiency and other advantages, laser cutting has become the most advanced and important material cutting method, and it is the most widely used laser processing technology in industry. It has been widely used in the industrial field. Laser cutting is the most important application technology in laser processing. It accounts for more than 70% of the entire laser processing industry and has become a highly competitive high-tech. [0003] When the existing laser pipe cutting machine cuts, it always fixes a cutting position, and the pipe moves forward step by step, and the cutting operation is performed at the cutting position. If the pipe is not cut, it is easy to cause a Danger, such as the rotation of the pipe driving the uncut part to collide with the feeding...

AI Technical Summary

Problems solved by technology

[0003] When the existing laser pipe cutting machine cuts, it always fixes a cutting position, and the pipe moves forward step by step, and the cutting operation is performed at the cutting position. If the pipe is not cut, it is easy to cause a Danger, such as the rotation of the pipe driving the uncut part to collide with the feeding mechanism or the rotation of the pipe driving the uncut part to collide with the cutting head, resulting in unnecessary losses

[0004] In addition, the existing pipes also distinguish between straight cutting and oblique cutting, and the detection methods of the two are different. Therefore, different detection methods need to be carried out according to the cutting type
