Problems solved by technology

[0002] The transportation of oil and natural gas is generally carried out through large-diameter pipelines. When laying pipelines, it is often necessary to cut and weld the pipes according to the actual construction conditions. The cutting work is generally carried out by ordinary cutting machines. Due to defects such as difficult positioning, low efficiency, and safety risks caused by the production of a large amount of metal chips during the cutting process, it is necessary to design a cutting machine with reliable positioning during pipe cutting, high cutting efficiency, and the safety of construction personnel can be effectively guaranteed

Abstract

The invention provides a multi-caliber pipe cutting machine. The multi-caliber pipe cutting machine comprises a cutting mechanism and a positioning mechanism located below the cutting mechanism. The positioning mechanism comprises a cutting platform and lock plates. A plurality of lock plate positioning groove sets are evenly distributed on the cutting platform in the length direction of a pipe. Each lock plate positioning groove set comprises two symmetrically-arranged lock plate positioning grooves each matched with a lock plate. After the corresponding lock plates are installed in the two lock plate positioning grooves of each lock plate positioning groove set, the lock plates are of a V-shaped structure. In each lock plate positioning groove set, the included angles formed by the axes of the lock plate positioning grooves and the upper surface of the cutting platform are different. According to the multi-caliber pipe cutting machine, various large-caliber pipes with different calibers can be cut, and it is avoided that when the pipes with different calibers are cut in the prior art, devices need to be replaced, and economic consumption and time consumption are caused. Meanwhile, the pipe positioning mechanism which is the most matched is appropriately selected, and the work efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of pipe material cutting machinery, and in particular relates to a multi-caliber pipe material cutting machine. Background technique [0002] The transportation of oil and natural gas is generally carried out through large-diameter pipelines. When laying pipelines, it is often necessary to cut and weld the pipes according to the actual construction conditions. The cutting work is generally carried out by ordinary cutting machines. Due to defects such as difficult positioning, low efficiency, and safety risks caused by the production of a large amount of metal chips during the cutting process, it is necessary to design a cutting machine with reliable positioning when cutting pipes, high cutting efficiency, and the safety of construction personnel can be effectively guaranteed. Contents of the invention [0003] In view of this, the present invention aims to propose a pipe cutting machine suitable for different calibe...
