Description

Technical Field

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

[0002] Hot-rolled seamless steel pipe, hot rolling is relative to cold rolling. Cold rolling is rolling below the recrystallization temperature, while hot rolling is rolling above the recrystallization temperature. During its production process, it is usually necessary to shear the rolled steel pipe according to actual needs to facilitate subsequent transportation and use. However, due to the curved surface of the steel pipe, it is difficult to fix it when cutting it by conventional means, which causes certain errors in subsequent cutting.

[0003] In the prior art, there is a shearing device for hot-rolled seamless steel pipe production with application number CN202121033864.5. In the above scheme, by "placing one end of the hot-rolled seamless steel pipe body on a fixed plate, the other end of the hot-rolled seamless steel pipe body passes through the first limiting wheel and the second limiting wheel, and by screwing the threaded rod, the threaded rod moves downward, and the threaded rod drives the clamping plate, and the clamping plate clamps one end of the hot-rolled seamless steel pipe body to achieve the clamping effect. By moving the moving rod left and right, the moving rod will be limited by the limiting groove A, and the sliding block will be in the sliding groove A. Sliding achieves the effect of adjusting the length of the hot-rolled seamless steel pipe body." However, it is supported by the fixed plate, two sets of first limiting wheels and the second limiting wheels. When the cutting wheel cuts off the seamless steel pipe, the fixed plate, a set of first limiting wheels and the second limiting wheels will support the upper section of the seamless steel pipe, but the other section of the seamless steel pipe is only supported by a set of first limiting wheels and the second limiting wheels. It is difficult to keep balance at both ends, which can easily cause one end to tilt and the other end to hit the ground, which can easily injure employees. It is inconvenient to position the two sections of seamless steel pipes that have been cut to reduce the risk of shaking and tilting. How to invent a cutting device for the production of seamless steel pipes to improve these problems has become an urgent problem for technicians in this field. Utility Model Content
