The types of agricultural machinery products tend to be diversified and specialized, among which the demand for large and medium-sized tractors, high-performance harvesting machinery, and large and medium-sized seeders has further increased. Typical mechanical equipment such as large and medium-horsepower tractors, medium and large wheat combine harvesters, and corn combine harvesters machine, no-tillage planter for wheat and corn, etc.
The sheet metal processing parts of agricultural machinery products generally use 4-6mm steel plates. There are many kinds of sheet metal parts, and they are updated quickly. The traditional sheet metal processing parts of agricultural machinery products usually use punching methods, and the mold loss is large. Usually a large agricultural machinery manufacturer is used for The warehouse where the molds are stored is nearly 300 square meters. If the processing of parts remains in the traditional way, it will seriously restrict the rapid upgrading of products and technological development, and the advantages of laser flexible processing are reflected.
Laser cutting is to use a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the gasification temperature and evaporated to form holes. ) to cut the seam to complete the cutting of the material.
Laser cutting machine processing not only has narrow slit, small deformation, high precision, high speed, high efficiency and low cost, but also avoids mold or tool replacement and shortens the production preparation time cycle. The laser beam does not exert any force on the workpiece, it is a non-contact cutting tool, which means that the workpiece has no mechanical deformation; the cutting material does not need to consider its hardness, that is, the laser cutting ability is not affected by the hardness of the material to be cut, any hardness. All materials can be cut.
Laser cutting has become the technological development direction of modern metal processing due to its high speed, high precision, high quality, energy saving and environmental protection. Compared with other cutting methods, the biggest difference between laser cutting is that it has the characteristics of high speed, high precision and high adaptability. At the same time, it also has the advantages of thin slit, small heat affected zone, good cutting surface quality, no noise during cutting, good verticality of the slit edge, smooth cutting edge, and easy automatic control of the cutting process.
The rapid development of the agricultural machinery industry and the accelerated replacement of products require advanced processing methods such as lasers to shorten the product development cycle and improve product production efficiency, especially for laser cutting of complex parts in newly developed products. It will gradually become an indispensable processing method in production, an emerging growth point to improve the modernization of agricultural machinery and equipment manufacturing, and an important technical support for the transformation of traditional agricultural machinery manufacturing. It is believed that the wide application of laser processing will definitely promote the rapid development of the agricultural machinery industry .
