The metal fiber laser cutting machine is composed of several main parts: circuit system, transmission system, cooling system, light source system and dust removal system. The key components that need to be maintained in daily use mainly include cooling system (to ensure constant temperature effect), dust removal system (to ensure dust removal effect), light source system (to ensure beam quality), and transmission system (to ensure normal operation). In addition, a good working environment and correct usage habits are also conducive to prolonging the service life of the equipment.
From the daily maintenance of several components summarized above, talk about how to extend the service life of the metal fiber laser cutting machine
Maintenance of cooling system
The water in the chiller needs to be replaced regularly, and the general replacement frequency is one week. The water quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use purified water or distilled water, and the water temperature should be controlled below 35°C. If you do not change the water for a long time, it is easy to form scale and block the waterway, so you must change the water regularly.
Second, let the water flow all the time. The cooling water is responsible for taking away the heat generated by the laser tube. The higher the water temperature, the lower the light output power (15-20°C is better); when the water is cut off, the tube end will burst or even damage the laser power supply due to the heat accumulated in the laser cavity. Therefore, it is very necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard bend (dead bend) or falls off, causing the water pump to malfunction, it must be repaired in time to avoid a drop in the power supply or even damage to the equipment.
Maintenance of dust removal system
After the fan is used for a long time, a large amount of dust will accumulate, which will affect the exhaust and deodorization effect, and also produce noise. When it is found that the fan suction is insufficient and the exhaust smoke is not smooth, first, turn off the power, eliminate the inlet and outlet ducts of the fan, remove the dust inside, then turn the fan upside down, stir the air in the blades until it is clean, and then install the fan. Fan maintenance cycle: about 1 month.
Maintenance of light source system
After the machine has been working for a period of time, the surface of the lens will be coated with a layer of ash due to the working environment, which reduces the reflectivity and transmittance of the reflective lens, and ultimately affects the working power of the laser. At this time, use the alcohol cotton soaked with absorbent to carefully rotate and wipe along the center of the lens to the edge. The lens should be wiped gently to not damage the surface coating; the lens should be handled gently during the wiping process to prevent falling; when installing the focusing lens, make sure that the concave surface is facing down. In addition, the use of ultra-high-speed punches should be minimized. Using conventional punches can extend the service life of the focusing lens.
Drive system maintenance
The equipment will generate smoke and dust during the long-term cutting process, and the fine smoke and dust will enter the equipment through the dust cover and adhere to the top of the rail frame. Long-term accumulation will increase the wear of the rail frame. The rack guide is a relatively accurate accessory. A large amount of dust deposits guides. The surface of the straight tube has a great influence on the processing accuracy of the equipment for a long time. It will guide the surface of the straight tube to form corrosion points and shorten the service life of the equipment. Therefore, in order to ensure the normal and stable operation of the equipment and ensure the processing quality of the products, the guide rails and straight cylinders must be carefully maintained daily and dust removed regularly. After cleaning the dust, grease the rack and lubricate the guide rails. Each bearing should also be oiled regularly to maintain flexible transmission, accurate processing, and prolong the service life of the machine.
Good working environment
Keep the workshop environment dry and well ventilated, and the ambient temperature is between 4°C and 33°C. Pay attention to the anti-dew of the equipment in summer and the anti-freeze of the laser equipment in winter.
The equipment should be far away from electrical equipment sensitive to electromagnetic interference to prevent long-term electromagnetic interference. Keep away from sudden interference from equipment with high power and strong vibration. Large battery interference sometimes causes the machine to malfunction. Although this situation is rare, it should be avoided as much as possible. Therefore, large electric welding machines, large electric mixers and large power transmission and transformation equipment should be kept away. Needless to say, for equipment with strong vibrations, such as forging presses, vibrations caused by close-range movement of motor vehicles, etc., the obvious vibration of the ground is very unfavorable for precise engraving.
Other preventive measures
During the working process of the equipment, the operator should observe the working status of the equipment at any time. In the event of an abnormal situation, immediately cut off all power sources, investigate or report to the supervisor in time, and actively take corresponding measures. Regularly count the use of the machine, and regularly record each part of the metal fiber laser cutting machine. If the effect is not good, replace it in time to prevent it.
Before determining whether the material can be irradiated or heated by the laser, do not process it to avoid the potential hazards of smoke and steam and damage to the laser equipment.
If you use the above daily maintenance skills, I believe your equipment will last longer and be more efficient!
