When we use portable flame cutting equipment for cutting operations, we will inevitably perform some graphic cutting, taking cutting circles as an example. Next, the editor of Sichuan cutting equipment manufacturer Xiaobian will explain cutting techniques for you:
For large-volume parts, a portable flame cutter can be used to cut the profile. Before cutting, a template must be made. The template for profile cutting can be made of 3 ~ 5mm steel plate, and a hole with a diameter of 10.5mm is drilled in the center. Load the sample program. Before cutting with a portable flame cutter, you can move the arm handwheel to adjust the template to a reasonable position. When cutting, unscrew the pressure valve to start cutting automatically.
1. The portable flame cutting machine punches a sample in the center of the round piece, making it as large as possible to prevent the top from sliding out.
2. The portable flame cutting machine adjusts the cutting circle radius through the elastic top wire, and makes the center of the mouth cover coincide with the cutting line by visual observation.
3.8.3 Put the cutting nozzle into the mouthpiece after ignition, then center the cone.
4. Preheat the steel plate. When the molten state appears, you can open the cutting oxygen valve to cut. When you hear the sound of "噗噗" under the plate, it means that it has been cut through. You can judge the cut through according to the severity of the sound. Degree to adjust the cutting speed.
