Plasma cutting torch

The plasma cutting gun is a processing method that uses the heat of the high-temperature plasma arc to locally melt the metal at the incision of the workpiece, and discharges the molten metal with the momentum of the high-speed plasma to form a slot. It is widely used because of its fast cutting speed, high cutting precision, easy setting of cutting conditions, easy automation, unmanned operation and relatively low cost. With the combination of information technology and control technology and plasma cutting, the newly developed plasma cutting machine has made great progress in design theory, design parameters, product quality and performance in recent years.
Plasma cutting can simplify the blanking process of the plate, combining the original cutting and stamping processes into one cutting process. At the same time, plasma cutting is easy to realize automation and improve work efficiency; it is easy to realize precise feeding, improve the utilization rate of materials, and is also conducive to maintaining the stability of product quality. More importantly, the application of plasma cutting can achieve mold-free cutting, avoiding the use of a large number of molds in production, and bringing great convenience to enterprise management.
When cutting, there are requirements for the inclination angle of the torch, cutting speed and oxygen pressure. The torch inclination is mainly related to the thickness of the workpiece. When cutting steel plates with a thickness of 5-20mm, the torch should be perpendicular to the workpiece without tilting. The straighter the torch, the better the quality of the cut and the smaller the kerf. When cutting a workpiece with a thickness of less than 5mm, it can be tilted forward to cut. If cutting a workpiece with a thickness of more than 30mm, the torch should be tilted backwards to cut. After cutting through, move the torch while cutting the torch to be perpendicular to the workpiece one by one. When the cutting is almost to the end, Then tilt the torch slightly inward until the cut is complete.
