Application of laser cutting technology in agricultural machinery manufacturing
Laser cutting technology applies a laser beam to the surface that needs to be processed for processing. At this time, a very high temperature will be formed on the surface to complete the processing. After the application of the laser beam, the oxidation reaction can be achieved. The steam and slag generated at this time can be directly discharged into the external space through the auxiliary gas, and then various shapes and sizes that meet the user’s requirements can be formed on the surface of the workpiece. In this way The entire processing process can be completed. In addition, laser cutting technology can cut titanium alloy, aluminum alloy, steel and other materials, and can also process special materials such as plastics, ceramics, glass, etc., so its application range is very wide. In addition, as a non-contact processing method, laser cutting technology will hardly have any impact on the performance of mechanical components. Its irradiation range is also relatively small, so the incision will be relatively thin, which can ensure the quality of the appearance of the slit. Therefore, the application of laser cutting technology to agricultural machinery manufacturing has obvious advantages over other cutting technologies and produces very good results.
Application of laser welding technology in agricultural machinery manufacturing
Laser welding technology mainly uses laser beam as a heat source to achieve heating treatment of materials, allowing the materials to melt directly, and then the welding process can be completed after cooling. This is also a non-contact processing method. During the laser welding process, the appropriate protective gas must be selected based on the characteristics of the material for welding processing to prevent adverse reactions in the molten pool. In addition, the rational use of laser welding technology can improve the efficiency of welding, make the operation more flexible and convenient, and will not produce large welding deformations. Moreover, there is no need to eliminate stress after welding, and heat treatment can achieve the desired results. Effect. For example, in the processing of large agricultural machinery – harvesters, the application of laser welding technology for connecting gearbox gears has very obvious advantages. The precision of the processed parts is relatively high, and with the continuous rapid development of this technology, the technical level has been greatly improved. With the improvement, it is also used more frequently in the field of agricultural machinery. There are many agricultural machinery, equipment or agricultural vehicles that are commonly processed by laser welding technology. This technology can promote the improvement of welding quality, greatly improve the performance of machinery manufacturing and production processes, and lay a solid foundation for the development of agricultural machinery.
Application of laser cladding technology in agricultural machinery manufacturing
This technology mainly puts powdery cladding materials directly into the outer surface of the base structure through preset, synchronization and other modes, and then uses a higher energy laser beam to carry out the process. Irradiation, after high-temperature reaction, can ensure that the thin layer of the cladding material and the outer surface of the substrate directly forms an integral structure, which can ensure that the quality of the outer surface meets the requirements. The outer surface formed by this processing method can achieve high temperature resistance and corrosion resistance. , wear resistance and other effects, and improve the surface performance of the component structure. In addition, from the analysis of laser cladding technology, it will not have an adverse effect on the body structure of the processed parts, nor will it damage its performance. This technology can be used to achieve perfect integration between the cladding layer and the body, improving the overall structural components. performance. Powder cladding materials are selected according to different needs, and intelligent processing can be achieved to promote overall performance improvement. Currently, this technology is widely used in the repair of parts. For example, if a large component such as a large agricultural machinery or a harvester is seriously damaged, replacing the entire equipment requires a large investment. However, for unimportant structural positions, it can be repaired through Laser cladding technology is used for repair processing to improve the integrity of structural components.
Application of laser additive processing technology in agricultural machinery manufacturing
Laser additive processing technology is what we call three-dimensional printing technology. This technology uses high-energy laser during processing to achieve processing according to the prescribed 3D model, and the alloy powder is Processed with other materials to form a solid component of the 3D model. In addition, the currently applied SLM (selective laser melting) technology has obvious advantages and is developing very fast. Among them, the so-called SLM technology is to lay the powder that meets the requirements on the surface of the workpiece, and then directly scan the metal powder through the laser beam according to the specified power to achieve comprehensive melting, and finally form the surface structure of the object through cooling, hardening and other reactions. In agricultural machinery manufacturing, the application of laser additive processing technology does not require the use of molds. The processing speed is very fast and the manufacturing level is relatively high.
Comparative analysis of the future development trend of laser processing technology in the field of agricultural machinery manufacturing with other developed countries. my country’s laser processing technology started relatively late and developed slowly. The technical level is far less than that of other developed countries, but it has also made progress. certain results. In recent years, laser processing technology has played a very important role in the field of agricultural machinery manufacturing, and the growth rate is very obvious. However, relatively speaking, the cost of laser processing technology is slightly higher than other processing technologies, so its application in the field of agricultural machinery manufacturing is still very limited. However, through the joint efforts of R&D personnel, the level of processing technology has been greatly improved, and automation and intelligence have been gradually realized. Through the integration and application of computer technology, the level of laser processing technology has been improved, and there will inevitably be broader development in the future. space.
