Description

Pipe Cutting and Chamferring Aparatus}

The present invention relates to a pipe cutting and beveling processing device for cutting a pipe, and more particularly, to providing a pipe cutting and cutting surface beveling processing device capable of performing a chamfering process for welding a cut surface while cutting a pipe.

In general, pipes are manufactured to a certain length according to KS standards or manufacturers' standards. When such a pipe is used in the field, it is used after being cut to a required length.

When working on ships and plants, the pipe is cut on site and the chamfering process is performed manually by grinding the cut part at about 30 degrees for welding. A lot of noise, dust, and safety accidents occur during grinding work. Currently, pipe cutting is done with automatic and manual hacksaws or oxygen. Small pipes are chamfered at about 30 degrees on lathes, and large pipes are cut with electric tools. I am doing manual work with a grinder. This developed product is a device developed for the purpose of preventing noise, dust, and safety accidents by fixing the pipe and rotating the cutting and chamfering processing tools.

When welding with pipe cutters currently on the market, use a saw blade to cut to length, and when welding pipes, chamfer about 30 degrees for welding. Small pipes are processed on a lathe machine, but large pipes was manually operated with an electric grinder, resulting in a lot of noise, dust, and safety accidents.
