[Up knowledge] CNC flame cutting machine safety operation specification

The application of CNC flame cutting machine is mainly limited to carbon steel, large thickness plate cutting, in the middle, thin carbon steel plate cutting will be gradually replaced by plasma cutting. The following Xiao Bian will introduce the safe operation specification of CNC flame cutting machine to all of you.

CNC flame cutting machine safety operating specifications

1, flame cutting machine operators must be qualified before training.

2. Operators must wear good protection products as required to enter the work position.

3, the operator should clean the material near the cutting machine to prevent safe operation.

4. Before the operator officially starts the machine, it is necessary to thoroughly inspect whether there are any abnormalities in various parts of the equipment. If abnormal conditions are found, the operator shall immediately report to the production manager and take effective measures to eliminate abnormalities before preparing for starting.

5. Before starting the machine, lubricate the specified lubrication points.

6, before and after the formal cutting run up and down to see if it is normal.

7, to see whether the gas source pressure gauge pointer position requirements, if the gas source pressure gauge indicates too low, indicating that the gas source pressure is insufficient, should adjust the gas cylinder control valve or update cylinder.

8, after all the pre-check is normal, you can press the prescribed program to start the operation.

9. Under normal working conditions, always pay attention to the operation of the equipment. If there is any abnormality, the equipment must be shut down and then work. The shutdown should be performed according to the shutdown procedure.

10. Pay attention to the safety operation when lifting the upper plate and the lower piece. If you need to stand on the support table to do things, pay special attention to falls and scratches.

11. Adjust the gas pressure according to the thickness of the workpiece during work.

12. At the end of the work, turn off the power supply and air supply. Clean up the site. At the same time, clean the surface of the vertical and horizontal guide rails with dirt and dust.

Using CNC flame cutting machine tips

CNC flame cutting machine generally use neutral flame or slight oxidation flame. During the cutting process, it is necessary to ensure that the strength of the flame is moderate, and the preheating flame should be selected according to the thickness of the workpiece, the type of nozzle, and the quality requirements.

When gas cutting thick steel plate, gantry type CNC flame cutting machine is slow in gas cutting speed. In order to prevent the upper edge of kerf to melt, the flame energy rate should be reduced accordingly; if the flame energy rate is too high, continuous beads will be produced on the upper edge of the kerf. Steel grains, even melted into rounded corners, also cause the slag on the back of the slit to increase, affecting the quality of the gas cutting. For example, when gas thinning steel sheet, because of the fast gas cutting speed, the flame energy rate can be increased accordingly, but the cutting nozzle should be far away from the workpiece and keep a certain inclination angle; if the flame energy rate is too small at this time, the workpiece will not get enough heat. It will slow the cutting speed and even interrupt the gas cutting process.

Here are some tips we use to summarize:

1. The power of the preheating flame should be increased with the increase of the plate thickness. The thicker the cutting piece, the greater the power of the preheating flame;

2. When cutting thicker steel plates, mild carbonizing flame should be used to avoid collapse of the upper edge of the incision and also to make the outer flame longer.

3, the use of diffusion type cutting nozzle and oxygen cutting nozzle cutting thickness of 200mm below the steel plate, the flame power to select a larger number to accelerate the incision front heating to the ignition point, so as to obtain a higher cutting speed.

4. When cutting steel with high carbon content or alloying elements, the power of the preheating flame is higher because of their higher ignition temperature.

5. When cutting the groove with a single cutting nozzle, the slag is blown to the outside of the incision. In order to supplement the energy, the flame power must be increased.

CNC flame cutting machine combines the traditional flame cutting method with CNC automation technology, and can be used for cutting carbon steel and carbon steel plates with a thickness of more than 6mm. CNC flame cutting still occupies a large market in consideration of the steel use in the domestic market. .
