Robot laser cutting machine
Robot laser cutting machine adopts automatic robot motion technology and professional high-precision laser head. The laser output power is stable and the processing width is large. It can accurately cut metal materials of various thickness materials such as sheet metal and stainless steel.
In general, it is recommended to use a Robot laser cutting machine for cutting metal materials such as carbon steel sheets within 12 mm or stainless steel sheets within 10 mm. The Robot laser cutting machine has no cutting force and no distortion in processing: no tool wear and good material adaptability: whether it is simple or complicated parts, laser can be used for precision precision rapid cutting: its slit is narrow, cutting quality is good, and automation is high. Simple operation, low labor intensity, no pollution: automatic cutting and nesting of cutting can be realized, material utilization rate is improved, production cost is low, and economic benefits are good.
There are many factors to consider when purchasing a Robot laser cutting machine. In addition to considering the maximum size, material, maximum thickness of the workpiece to be cut, and the size of the raw material, more needs to be considered in the future. The maximum workpiece size to be processed after the technical modification, the material of the material provided by the steel market, which is the most material for the product, the loading and unloading time, and so on.
Cutting advantage of Robot laser cutting machine
1. High cutting precision: Robot laser cutting machine positioning accuracy 0.05mm, repeat positioning accuracy 0.03 mm.
2. Robot laser cutting machine slit narrow: the laser beam is focused into a small spot, so that the focus reaches a very high power density, the material is quickly heated to the degree of gasification, evaporation to form holes. As the beam moves relatively linearly with the material, the holes are continuously formed into slits having a narrow width, and the slit width is generally 0.10-0.20 mm.
3. The cutting surface of the Robot laser cutting machine is smooth: the cutting surface has no burrs, and the surface roughness of the cutting surface is generally controlled within Ra6.5.
4. Robot laser cutting machine speed: cutting speed up to 10m / min and maximum positioning speed up to 30m / min faster than the line cutting speed.
5. Robot laser cutting machine cutting quality is good: no contact cutting, cutting edge is affected by heat, there is basically no thermal deformation of the workpiece, completely avoiding the collapse formed when the material is punched and sheared, the slit generally does not require secondary processing.
6. Does not damage the workpiece: the laser cutting head will not contact the surface of the material to ensure that the workpiece is not scratched.
7. Not affected by the shape of the workpiece: laser processing is flexible, can process any graphics, can cut pipes and other profiles.
8. Saving mold investment: laser processing does not require molds, no mold consumption, no need to repair molds, saving mold time, thus saving processing costs and reducing production costs, especially suitable for processing large products.
9. Material saving: computer programming can be used to cut products of different shapes to maximize the utilization of materials.
10. Improve the speed of sample delivery: after the product drawings are formed, laser processing can be performed immediately, and the new product can be obtained in the shortest time.
11. Safety and environmental protection: laser processing waste, low noise, clean, safe, non-polluting, greatly improving the working environment.
Advantages of Robot laser cutting machine over CO2 laser cutting machine:
1. Excellent beam quality: smaller focusing spot, finer cutting lines, higher work efficiency and better processing quality;
2. Extremely high cutting speed: twice the same power CO2 laser cutting machine;
3. High stability: using the world's top imported fiber laser, the performance is stable, and the service life of key components can reach 100,000 hours;
4. Extremely high electro-optical conversion efficiency: the photoelectric conversion efficiency of the Robot laser cutting machine is about 30%, which is 3 times higher than the CO2 laser cutting machine, energy saving and environmental protection;
5. Very low cost of use: the power consumption of the whole machine is only 20-30% of the same CO2 laser cutting machine;
6. Very low maintenance cost: no laser working gas; optical fiber transmission without reflection lens; can save a lot of maintenance costs;
7. Convenient operation and maintenance of the product: optical fiber transmission, no need to adjust the optical path;
8. Super flexible light guiding effect: compact size, compact structure and easy flexible processing requirements.
Of course, the cutting range of the Robot laser cutting machine is relatively narrow compared to the CO2 laser cutting machine. Because of the wavelength, it can only cut metal materials, it is not easy to be absorbed by non-metals, thus affecting its cutting range.
Robot laser cutting machine for automotive parts
Robot laser cutting machine has a high degree of flexibility. Under normal conditions, a set of molds can only be used for one workpiece, and Robot laser cutting machine can be applied to any workpiece. When the workpiece product changes, such as changes in the surface, trimming, and holes, it is only necessary to change the offline program of the Robot laser cutting machine. Because the fixtures used are relatively simple, the fixtures are also easy to change. Therefore, Robot laser cutting machine has more flexibility, which can reduce the investment of the mold and shorten the trial period of the sample.
Laser cutting uses non-contact processing, which has almost no consumables and no contaminants. The Robot laser cutting machine can also solve the problem of cutting and trimming of some three-dimensional metal parts. At present, Robot laser cutting machine applications still have certain problems in automotive parts, such as machining accuracy and production efficiency, which cannot meet the requirements of the automotive thermoforming line industry.
However, in the developed industrial countries of Europe and America, 50% to 70% of auto parts are processed by laser processing. China's laser cutting has a vast space in the field of auto parts processing. As the Robot laser cutting machine becomes more and more mature, the machining accuracy and processing efficiency will inevitably increase. At that time, the application of the Robot laser cutting machine will become wider and wider.
