Description

Technical Field

[0001] The invention relates to the technical field of plasma cutting, and in particular to a plasma cutting machine for processing scrapped vehicles. Background Art

[0002] Plasma cutting is a technology that uses a high-temperature plasma arc to cut metal materials. Its working principle is to ionize the gas through a high-frequency arc to form a plasma, and then blow the plasma out of the cutting torch through high-pressure gas. The high temperature and high-speed momentum are used to melt and blow away the metal, thus forming an incision. It is suitable for industries such as automobiles, locomotives, and pressure vessels, and is widely used in the processing of various metal materials.

[0003] In recent years, with the increasing rate of automobile scrapping, plasma cutting machines have gradually been used in the cutting of scrapped cars. Traditional scrapped cars are mostly disassembled by dismantling machines first, and then thin metal plates are sheared by shearing machines.
