Working principle and application of plasma bevel cutting machine

　　Plasma bevel cutting machine is an advanced equipment based on plasma arc cutting technology and can bend processing of metal materials. The working principle is to use high-temperature plasma arcs to instantly melt and blow away the metal to achieve the purpose of cutting. When used for bevel cutting, through precise mechanical devices and control systems, metal sheets or pipes can be cut at set angles to form bevels of various shapes and angles.

　　The plasma bevel cutting machine has a unique structure. It usually consists of cutting guns, power supply systems, control systems, workbenches and gas supply systems. The cutting gun is a key component that directly contacts metal materials and produces plasma arcs. It is exquisitely designed, and components such as internal electrodes and nozzles work together to ensure the stable generation of plasma arcs. The power supply system provides powerful and stable electrical energy for the entire cutting process, and its power magnitude directly affects the thickness and speed of the cutting. The control system is like the brain of the device. Through it, the operator inputs cutting parameters, such as cutting speed, bevel angle, cutting current, etc., and then the control system accurately directs the equipment to operate as required. There are many types of workbench designs, some are flat workbenches for cutting boards; some are equipped with clamps and rollers to allow stable cutting of pipes. The gas supply system provides the necessary working gases for the generation of plasma arcs, such as argon, nitrogen, etc. The purity and flow of the gas have an important impact on the cutting quality.

　　Plasma bevel cutting machines have many advantages. First of all, the cutting accuracy is high. The bevels of various angles can be accurately cut out, and the angle error can be controlled within a very small range, which is very critical for the manufacturing of some structural parts with extremely high requirements for welding quality. For example, in the manufacturing of pressure vessels, precise bevel cutting can ensure good sealing performance of the container after welding. The second is the cutting speed. Compared with traditional cutting methods, such as flame cutting, plasma bevel cutting machines can complete cutting tasks at a faster speed, greatly improving production efficiency. Good cutting quality. The cutting surface is smooth and there are no obvious cut patterns and burrs, which reduces the workload of subsequent processing. It can cut a variety of metal materials, whether it is carbon steel, stainless steel or aluminum alloy, etc., and can be easily dealt with by plasma bevel cutting machines.

　　In the ship manufacturing industry, plasma bevel cutting machines are widely used. The hull structure of a ship is spliced ​​with a large number of steel plates that need to be beveled for welding. The plasma bevel cutting machine can quickly and accurately cut out bevels that meet the requirements, ensuring the strength and sealing of the hull structure. In the field of building steel structure manufacturing, it is also indispensable. From steel beams in tall buildings to steel trusses in large venues, plasma bevel cutting machines can provide high-quality bevel cutting services for the processing of steel structure components.

　　However, plasma bevel cutting machines also have some limitations. For example, the initial investment cost of equipment is relatively high, which can be a significant burden for some small businesses. Moreover, the operation and maintenance of equipment requires certain professional knowledge and skills, and the requirements for operators are high.
