Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts processing, and particularly relates to a plasma cutting device for automotive parts processing. Background Art

[0002] A plasma cutting machine is a machine that processes metal materials by means of plasma cutting technology. Plasma cutting is a processing method in which the heat of a high-temperature plasma arc is used to melt part or locally melt the metal at the workpiece cutting edge, and the molten metal is removed by the momentum of the high-speed plasma to form a cutting edge. Plasma cutting machines are widely used in various industries such as automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, and steel structures. Automotive parts are the various units that make up an automobile as a whole and a kind of product that serves the automobile. With the improvement of people's living standards, people's consumption of automobiles is increasing, and the market for automotive parts is also getting larger. In recent years, automotive parts manufacturing plants have also been developing rapidly. After some automotive parts are die-cast through the die-casting process and first become die-cast blanks, they need to go through a series of processes such as cutting and grinding before they can be made into finished parts.

[0003] Currently, most of the cutting of automotive parts steel plates is carried out using a plasma cutting machine. However, after the current plasma cutting machine finishes cutting the automotive parts steel plate, there will be burrs on the cutting surface, and it is not possible to grind the automotive parts steel plate in a timely manner. It needs to be transferred to a grinding device for grinding, which affects the quality of the automotive parts steel plate after cutting and increases the subsequent processing time, thus reducing the work efficiency. For this reason, we provide a plasma cutting device for automotive parts processing to solve the above problems. Summary of the Invention
