As high-precision and high-efficiency cutting equipment, laser tube cutting machines have been widely used in the field of pipe processing. However, during actual use, laser tube cutting machines will also encounter some common problems, which not only affect the cutting quality but may also reduce production efficiency. This article will analyze several common problems when cutting pipes with laser pipe cutting machines, and propose corresponding solutions.
Cutting accuracy is not high
If the laser tube cutting machine has low cutting accuracy when cutting pipes, it may be due to the following reasons:
1. The laser beam is improperly adjusted. Parameters such as the focal length, position, and angle of the laser beam have an important impact on cutting accuracy. If the adjustment is not accurate, the cutting surface will be uneven or even cutting deviation will occur.
2. The surface of the pipe is uneven. If there is an oil stain, oxide layer, or unevenness on the surface of the pipe, it will affect the focusing effect of the laser beam, thus affecting the cutting accuracy.
Solution:
1. Precisely adjust the laser beam. According to the material and thickness of the pipe, adjust the focus, position, and angle of the laser beam to ensure that the laser beam is perpendicular to the pipe surface to obtain the best cutting effect.
2. Pretreat the pipe surface. Before cutting, clean the surface of the pipe to remove oil stains and oxide layers to ensure a smooth surface. If the surface of the pipe is uneven, pretreatment can be performed, such as grinding, polishing, etc., to improve cutting accuracy.
Cutting speed is unstable
When laser tube cutting machines cut pipes, unstable cutting speed is also a common problem. Cutting too fast may result in incomplete cuts, while cutting too slowly may waste time and energy. Cause Analysis:
1. The laser power is unstable. Fluctuations in laser power directly affect cutting speed. If the laser power is unstable, the cutting speed will be unstable.
2. The pipe material is uneven. Pipes of different materials have different absorption capabilities for lasers. If the pipe material is uneven, the cutting speed will be unstable.
Solution:
1. Check the laser generator. Regularly inspect and maintain the laser generator to ensure stable output power. If you find that the laser power is unstable, you should contact a professional for repair in time.
2. Choose the appropriate pipe material. When selecting pipes, try to choose pipes with uniform material and stable quality to reduce instability in cutting speed.
Poor cutting surface quality
After the laser tube cutting machine cuts the pipe, the quality of the cutting surface is also an important indicator of the cutting effect. If burrs, cracks, and other problems appear on the cutting surface, it will not only affect the aesthetics of the tube but may also affect the performance of the pipe. Cause Analysis:
1. Improper setting of cutting parameters. Cutting parameters include laser power, cutting speed, auxiliary gas pressure, etc. The settings of these parameters have an important impact on the quality of the cutting surface. If the parameters are set incorrectly, poor quality of the cutting surface will result.
2. The internal stress of the pipe is too large. Pipes may produce internal stresses during the production process, and these stresses will be released during the cutting process, causing problems such as cracks on the cutting surface.
Solution:
1. Optimize cutting parameters. According to the material, thickness, and cutting requirements of the pipe, parameters such as laser power, cutting speed, and auxiliary gas pressure should be reasonably set to obtain the best cutting surface quality.
2. Anneal the pipe. Annealing the pipe before cutting can effectively reduce internal stress and improve the quality of the cutting surface.
Common problems when laser tube cutting machines cut pipes include low cutting accuracy, unstable cutting speed, and poor cutting surface quality. To address these problems, we can improve the cutting effect of the laser tube cutting machine and improve production efficiency by adjusting the laser beam, pretreating the pipe surface, checking the laser generator, selecting the appropriate pipe, optimizing cutting parameters, and performing annealing treatment. With the continuous advancement of technology and the accumulation of application experience, it is believed that the application of laser tube cutting machines in the field of pipe processing will become more and more extensive.
