Automatic pipe cutting device and pipeline cutting method

Abstract

The invention relates to the technical field of pipeline cutting equipment, in particular to an automatic pipe cutting device and a pipeline cutting method. The automatic pipe cutting device comprises a feeding mechanism and a clamping and cutting mechanism, wherein the clamping and cutting mechanism comprises a hollow rotating roller, the rotating roller is sleeved with a gear ring, and the gear ring is meshed with a gear at the shaft end of a rotating motor I. The automatic pipe cutting device further comprises an annular fixed sliding groove sleeve, wherein the fixed sliding groove sleeve is in sliding connection with an even number of sliding keys, the sliding keys are fixedly connected with sub-cones, and the sub-cones are in sliding connection with a taper sleeve; the taper sleeve is connected with a push rod motor; the sub-cones located at the top and the bottom are each connected with a follow-up bearing, each follow-up bearing is fixedly connected with a sliding rod, and each sliding rod is sleeved with a spring; the sliding rod at the top is connected with a cutter; and the bottom sliding rod is connected with a carrier roller. The pipeline cutting method adopts the automatic pipeline cutting device to automatically cut the pipeline. According to the automatic pipe cutting device, pipes with different diameters can be cut, the pipes can be fixed during cutting, and the cutting effect is good.

Description

technical field [0001] The invention relates to the technical field of pipe cutting equipment, in particular to an automatic pipe cutting device and a pipe cutting method. Background technique [0002] Pipeline refers to the device used to transport gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. In the field of construction, pipes are used, and the pipes used in construction need to be cut, and pipe cutting devices are often used. [0003] But existing pipe cutting device has following shortcoming. 1. It can only cut pipes with ...

AI Technical Summary

Problems solved by technology

1. It can only cut pipes with a fixed diameter, and it is difficult to cut pipes of different sizes; 2. It is difficult to make the relevant mechanisms of the device touch the pipe, and it is difficult to fix the pipe during cutting; 3. The cutting blade cannot completely complete the pipe at one time Cut off, need to cut twice or even multiple times, resulting in uneven cutting surface
