Description

Technical Field

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

[0002] Seamless steel pipes have hollow cross-sections and are widely used as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when the bending and torsional strengths are the same. They are an economical cross-section steel material and are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. Using steel pipes to manufacture annular parts can improve material utilization, simplify the manufacturing process, save materials and processing time, and have been widely manufactured using steel pipes. The existing patent, patent announcement number CN220659383U, discloses a seamless steel pipe cutting device, which belongs to the field of seamless steel pipe processing technology. The key points of its technical solution include a base, a cutter structure and a rotator, and the rotator is bolted to the left side of the top of the base. The cutter structure is slidably connected to the rear side of the top of the base, and the front side of the top of the base is slidably connected to a moving seat. A support seat is arranged on the top of the moving seat, and two supporting wheel structures are slidably connected to the top of the support seat, which solves the problem that the existing seamless steel pipe uses a head cutting device to cut the seamless steel pipe according to needs during the production and processing process. Since the seamless steel pipe is manufactured as a whole, there are different sizes and specifications. The conventional head cutting device for seamless steel pipes has the problem that it is not convenient to adjust the uniform height for seamless steel pipes of different sizes and specifications. Therefore, the use of the seamless head cutting device has certain limitations, thereby affecting the use effect.

[0003] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, waste chips will splash and cannot be collected centrally; during the cutting process, waste chips will splash with the saw blade, affecting the safety of the subsequent working environment, and also requiring subsequent cleaning, which affects the convenience of using the device and reduces the safety of using the device. Therefore, we proposed a seamless steel pipe cutting device to solve the above-mentioned problems. Utility Model Content
