Pipe cutting assembly and pipe cutting device thereof

Abstract

The invention provides a pipe cutting assembly and a pipe cutting device thereof. The pipe cutting assembly comprises a plurality of cutting heads and a transmission mechanism, and the transmission mechanism comprises a shell with a containing cavity, a driving wheel arranged in the shell and a plurality of driven wheels rotating along with rotation of the driving wheel. Each cutting head is arranged on one driven wheel and can rotate along with the driven wheel, and the multiple cutting heads work at the same time, so that the pipe cutting efficiency can be improved.

Description

technical field [0001] The invention relates to the field of pipe cutting, in particular to a pipe cutting assembly and a pipe cutting device. Background technique [0002] Some of the existing custom-made heat exchangers cannot be processed by automatic tube expansion equipment, and can only be manually expanded to realize the tight combination of heat-exchange copper tubes and heat-exchange aluminum sheets. After the tube expansion process is completed, the tube opening is uneven. At this time, it is necessary to use a tube cutting tool to cut the tube opening of the heat exchanger to facilitate welding of other pipelines. [0003] At present, after the tube expansion process is completed, the tube mouth is uneven, and the tube cutting tools on the market can only cut one tube at a time, resulting in low cutting efficiency. Contents of the invention [0004] In view of this, it is necessary to address the above problems and provide a pipe cutting assembly and a pipe cut...
