The automobile manufacturing industry needs laser cutting machine processing

The automobile manufacturing industry often needs laser cutting machine processing to cut the main materials. Traditional punching dies cannot be processed. Three-dimensional laser cutting is currently one of the very good solutions. Next, follow the Hebei Hongte CNC cutting machine manufacturer To understand the indissoluble bond between the automobile manufacturing industry and the laser cutting manufacturing industry.

As people With the increase in comfort and safety requirements, the development trend of the automobile industry is to increase the size of the body, the application of four-wheel drive technology and more electronic equipment, which inevitably lead to an increase in the weight of the finished car and the goal of reducing fuel consumption. The only solution is to reduce the weight of the car body without affecting performance. This can be verified from the internal high-pressure forming parts (IHU) and high-hardness steel (hot formed steel) that are currently widely used in the automotive body field.

In internal high-pressure molding, the outer wall of the hollow member (mainly tubular) in the mold is completely adhered to the mold with a high-pressure emulsion (water and additives). The parts produced by this method have high forming accuracy and light weight. It can form a variety of pipes that originally need to be welded at one time, reduce the number of welds, and improve the overall strength. It is widely used in automobile body and chassis structures, and has a good strength-to-weight ratio. The production cost is low. The shape of the internal high-pressure forming part is very complicated, and a certain number of holes and slots need to be cut. Traditional punching dies cannot be processed. Three-dimensional laser cutting is currently one of the very good solutions.

High-hardness steel (warm-shaped) has very high internal tension (1500MPa/mm2), so the elastic deformation is very small, and it is very suitable for the parts of the body that require strength, such as bumper struts, The position of the front beam, side beam and rim. Under the same strength requirements, the weight of high-hardness steel is much lower than that of ordinary steel, and many welding processes can be reduced. Therefore, the weight of the car body can be effectively reduced under the premise of ensuring safety. Therefore, parts made of this material are difficult to process with traditional die methods, and the solution is 3D laser cutting.

In advanced industrialized countries such as Europe and America, 50%~70% of auto parts are Finished by laser processing, the application of laser in the automobile industry is mainly laser welding and laser cutting. Laser cutting includes plane cutting and three-dimensional cutting.

Plane laser cutting

Cars need plane laser cutting technology, which is mainly used in auto parts, car bodies, roofs, doors, boxes, etc. Among them, laser cutting technology has particularly refined requirements for auto parts, especially key parts such as engines, because it is related to the stability and power performance of the car. Through the use of refined laser cutting methods, the accuracy of each component of the engine is effectively improved, and a revolutionary breakthrough has been brought to the development of the automobile manufacturing industry.

3D laser cutting

The 3D laser cutting machine is a laser processing equipment that is not restricted by the cutting direction and can cut freely. Multi-directional and multi-directional cutting processing can be performed on metal materials of different thicknesses. The application of 3D laser cutting technology in automobile manufacturing is mainly in cutting holes, trimming, steering wheel holes, etc. of automobile bodies and automobile body cover plates.

Laser cutting machine is a kind of advanced thermal cutting equipment that integrates multiple disciplines. It uses computer numerical control technology to integrate high-precision mechanical transmission and advanced laser. It has high efficiency, high precision and high flexibility. The characteristics of non-contact and low pollution will become more and more widespread under the current trend of car weight reduction.

For the automobile manufacturing industry, the application of laser cutting technology has driven industrial upgrading. For the entire manufacturing industry, laser cutting technology influences the globalization and smart manufacturing of Chinese manufacturing. As the world's manufacturing industry shifts to China, the demand for my country's laser cutting machines is also increasing. The laser cutting industry grew out of nothing, and now has a scale. Laser cutting machines not only have unlimited potential in the automotive manufacturing market, but also show amazing explosive power in other applications.
