Description

Technical Field

[0001] The utility model relates to the technical field of pipe-cutting machines, in particular to a full-automatic pipe-cutting machine. Background Art

[0002] The pipe cutting machine is a mechanical device specially used for cutting pipes. This machine can automatically cut the pipes to a fixed length and can automatically feed the pipes, which greatly improves the work efficiency and accuracy. It can be used for cutting the steel pipes of the disc-type steel scaffolding. However, the existing devices have certain disadvantages. For example, a fixed-length cutting device for the production of special-shaped steel pipes recorded in the publication number CN220659374U includes a cutting table and a support, the support is fixedly installed at the bottom end of the cutting table, and the top end of the cutting table is provided with a cutting mechanism and a clamping mechanism;

[0003] Although the above device solves the problem of sparks flying easily, which can easily cause injuries to workers, by setting up a clamping mechanism, the special-shaped steel pipe can be stably fixed. However, the steel pipe is not polished after cutting, resulting in burrs at the port position and possible debris on the surface of the steel pipe, which affects the subsequent welding and painting. Tools are needed for processing later, resulting in reduced scaffolding production efficiency. Utility Model Content
