How to use semi-automatic flame cutting machine to cut tracks

Try the machine before operation, so that problems can be found in advance. When the cutting machine is working, it is forbidden to adjust the saw or try to tighten small workpieces.

Don't force the saw, the motor should run at full speed. Everyone can stand behind the sawing table when using the cutting machine. When operating the cutting machine, it is not allowed to let go and bend over the sawing machine.

The gas flow rate should be adapted to the nozzle aperture. Large gas flow is beneficial to compress the arc, make the energy of plasma arc more concentrated, improve the working voltage, improve the cutting speed and blow off the molten metal.

When cutting, the starting point needs to be punched, and the cutting will stop at the starting point of Y axis, the end point of the first side X axis (the long side is X axis and the short side is Y axis), and then the cutting oxygen and air delivery will stop at the end point of Y axis, and then the cutting will start with punching.

Extended data

1, serious cutting deformation will make the size of the parts out of tolerance, affect the subsequent assembly and welding, and even cause scrap. Therefore, in order to reduce cutting deformation and improve the dimensional accuracy of cutting parts, the following measures are taken.

2. Choose a reasonable cutting sequence, cutting direction and cutting starting point when programming. When cutting and blanking multiple parts, the principle of "cutting small parts first, then cutting large parts" should be followed.

3. When cutting, the cutting deformation trend of the parts should be analyzed according to the shape of the parts and the position of the discharge on the steel plate, and the reasonable starting point and cutting direction should be determined.
