[0002] A corrugated pipe is a pipe with a wavy pleated structure, which is widely used in the fields of petroleum, chemical industry, aerospace, machinery manufacturing, etc. During the processing of the corrugated pipe, it needs to be cut according to the needs, so a cutting device is needed.

[0003] When cutting the corrugated tube, it is inconvenient to fix the corrugated tube, the corrugated tube is easy to roll, and it is inconvenient to quickly adjust the cutting position. If the cutting position needs to be adjusted after the corrugated tube is fixed, the corrugated tube needs to be loosened, and its position needs to be adjusted and then fixed again, which is very troublesome. Moreover, most of the cutting devices on the market cut the corrugated tube longitudinally or transversely. When cutting, the corrugated tube is stationary and the cutting blade moves. It is easy to cut crookedly during cutting, and the cutting efficiency is not high, so it is urgently needed to be improved. Summary of the invention

[0004] The object of the present invention is to provide a corrugated pipe cutting device and a cutting method thereof to solve the problems raised in the above background technology.

[0006] Preferably, a rubber patch is adhered to the surface of the clamping disk to increase the friction force on the surface of the clamping disk.

[0007] Preferably, arc-shaped support brackets are fixed to the top of the device base on both sides of the transverse guide rail to facilitate supporting the corrugated tube.

[0008] Preferably, a first servo motor is installed at one end of the transverse guide rail, and an output end of the first servo motor is fixedly connected to the guide screw to drive the guide screw to rotate.

[0009] Preferably, the bottom end of the longitudinal guide rail extends to the interior of the transverse guide rail and is threadedly connected to the guide screw.

[0010] Preferably, a friction plate is adhered to the top end of the arc-shaped clamping plate, thereby increasing the surface friction of the arc-shaped clamping plate.

[0011] Preferably, a third servo motor is installed on the outer wall of one side of the cutter, and the output end of the third servo motor is fixedly connected to the cutting blade to drive the cutting blade to rotate.

[0015] Step 1: Place the bellows on the arc-shaped support bracket at the top of the device base;

[0016] Step 2: Start the second servo motor by operating the external control.

The movable seat drives the clamping plate to clamp the two ends of the corrugated pipe. The electric telescopic rod drives the clamping rod to extend so that the arc-shaped clamping plate is against the inner wall of the corrugated pipe, so that the corrugated pipe can be quickly fixed. When the cutting position needs to be changed, the cutter can be moved by controlling the rotation of the guide screw. There is no need to repeatedly disassemble and clamp the corrugated pipe. The operation is simple and convenient. The third servo motor drives the cutting blade to rotate. Hold the handle and push the cutter to move toward the corrugated pipe. The cutter slides along the guide rod inside the longitudinal guide rail. When the cutting blade contacts the corrugated pipe, cutting can begin. At the same time, the reduction motor drives the clamping plate to rotate, and the clamping plate drives the corrugated pipe to rotate slowly. As the corrugated pipe rotates one circle, the corrugated pipe can be cut off. The cutting device adopts a dynamic cutting method with high cutting efficiency and can guide the movement of the cutting blade to make the cutting smooth and not skewed.
