Description

Technical Field

[0001] The utility model relates to the technical field of round pipes, in particular to an automatic cold saw cutting device for round pipes which is easy to fix. Background Art

[0002] A round tube refers to a steel material with openings at both ends and a hollow concentric circle section, and a large ratio of length to circumference. It can be used for pipelines, thermal equipment, mechanical industry, petroleum geological drilling, containers, chemical industry and special purposes. The sawing process of a metal circular saw is referred to as metal cold sawing. When metal is cold sawed, the heat generated by the saw teeth of the saw blade when sawing the workpiece is transferred to the sawdust through the saw teeth, and the sawed workpiece and the saw blade remain cool, hence the name cold sawing. The saw blade does not have any surface treatment and is mainly used for sawing non-ferrous metal materials such as copper and aluminum. The main advantage is that the saw blade is thin, and sawing non-ferrous metals such as copper can greatly reduce material loss and save costs.

[0003] When cutting a round tube, since the inside of the round tube is hollow, the round tube is subjected to the cutting pressure during cutting, which can easily cause deformation at the cutting position, resulting in the cutting position of the round tube being unable to remain flat. The round tube needs to be trimmed again, which brings inconvenience to the cutting of the round tube. Therefore, we propose an automatic cold saw cutting device for round tubes that is easy to fix.
