[0023] The specific implementation method is as follows: the second telescopic component 2 drives the pressure regulating mechanism 3 and the cutting component 5 to move and squeeze the outer wall of the steel pipe for cutting. When the squeezing force is too large, the second mounting block 304 and the slide rod 303 will overcome the elastic force of the spring 308 and move into the inside of the threaded sleeve 302. The above means limit the maximum pressure of the cutting component 5 on the outer wall of the steel pipe. Through the cooperation between the through-shaft linear stepper motor 306, the buckle 307 and the limit rod 305, the through-shaft linear stepper motor 306 can move up and down on the outer wall of the threaded sleeve 302 during operation, changing the degree of contraction of the spring 308.

[0026] Working principle: When using this seamless steel pipe circumferential cutting machine, the second telescopic component 2 drives the pressure regulating mechanism 3 and the cutting component 5 to move and squeeze the outer wall of the steel pipe for cutting. When the squeezing force is too large, the second mounting block 304 and the slide rod 303 will overcome the elastic force of the spring 308 and move into the inside of the threaded sleeve 302. Through the above means, the maximum pressure of the cutting component 5 on the outer wall of the steel pipe is limited.

According to Hooke's law, the external force value that causes the spring 308 to deform can be changed through the above means. In summary, this equipment has the function of limiting the maximum pressure of the cutting equipment on the outer wall of the steel pipe and is adjustable.

The cooperation between the drive motor 102, gear 103 and mounting plate 104 drives several second telescopic components 2, pressure adjustment mechanism 3 and cutting component 5 to rotate along the outer wall of the steel pipe to cut.
