TECHNICAL FIELD

[0001] The application relates to the technical field of pipe cutting, in particular to a cutting device for special-shaped steel pipes. BACKGROUND

[0002] Special-shaped steel pipes play an important role in modern industrial manufacturing and are widely used in mechanical processing, construction and aerospace fields. With the continuous progress of industrial technology, the demand for special-shaped steel pipe cutting equipment is increasing. Efficient cutting equipment not only improves production efficiency, but also ensures cutting precision and surface quality, thereby meeting the diversified needs of different industries for special-shaped steel pipes. However, traditional cutting technology often fails to balance cutting precision and stability when facing complex-shaped special-shaped steel pipes, which becomes an important factor restricting the development of the industry.

[0003] The existing special-shaped steel pipe cutting equipment has some problems in actual application. The support and positioning of the special-shaped steel pipe during cutting are not stable enough, and the steel pipe is easily displaced due to cutting vibration, affecting the cutting precision. And in the cutting process, it is difficult to effectively reduce the influence of cutting vibration on the special-shaped steel pipe. Especially when cutting complex-shaped special-shaped steel pipes, the traditional clamping method is difficult to provide enough supporting force, causing the steel pipe to easily deviate in position during cutting, thereby affecting the cutting precision and surface quality.

[0004] In view of the above-mentioned related technologies, it is necessary to provide a cutting device for special-shaped steel pipes to solve one of the above technical problems. SUMMARY
