Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe cutting, in particular to a cutting device for steel pipe processing. Background Art

[0002] Steel pipes are important raw materials in modern industry. They are used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and engineering structures.

[0003] When cutting steel pipes, the steel pipes are clamped and fixed, and then a cutting machine is used to directly cut the steel pipes. The cutting blade needs to move downward to cut the entire steel pipe. If a thicker steel pipe is cut, a larger cutting knife is required. The large cutting knife is not only more expensive, but also the cutting knife has to penetrate deeper into the steel pipe during cutting, which can easily cause damage to the blade. For this reason, we propose a cutting device for steel pipe processing. Utility Model Content

[0004] The main purpose of the utility model is to provide a cutting device for steel pipe processing, which can effectively solve the problems in the background technology.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The cutting device for steel pipe processing is arranged through the coordination between a positioning frame, a positioning tube, a limit frame, a threaded rod, an upper arc plate, a lower arc plate, a gear ring, a driving gear, a servo motor, a control motor and a cutting knife. When the steel pipe needs to be cut, the steel pipe is inserted into the positioning tube and placed on the lower arc plate.
