Laser cutting is a high-tech developed in recent decades. Compared with the traditional cutting process, it has the characteristics of higher cutting accuracy, lower roughness, higher material utilization and production efficiency. Especially in the field of fine cutting, laser cutting has incomparable advantages over traditional cutting. Laser cutting machine is a non-contact, high-speed and high-precision cutting method that focuses energy on a small space and uses high-density energy.
In the manufacturing process of electrical appliances, there are many sheet metal parts and parts, and the shape is complex, the process is difficult, and in the processing process, a large number of tooling and molds are required to ensure the processing quality. Laser cutting technology in the electrical industry can not only effectively solve the above problems, but also play an important role and value in improving the processing quality of workpieces, saving processing links and processing costs, shortening the manufacturing cycle of products, reducing labor and processing costs, and improving processing efficiency in a large scale.
In the electrical industry, laser cutting machine is mainly used to cut sheet metal parts in the appearance and in the installation of complete sets of electrical components. Nowadays, many electrical appliance factories have adopted this new technology, which has improved the product quality, reduced the production cost, reduced the labor intensity, improved the traditional plate processing technology, and received better production benefits. Current situation of sheet metal processing technology in the electrical industry in electrical products, metal sheet parts account for almost more than 30% of all product parts. The traditional cutting, corner cutting, hole opening, trimming and other processes are relatively backward, which directly affects the product quality and production cost. The reasons are analyzed as follows:
1. A large number of molds are required for processing with traditional punch. Electrical products have many hole sizes and shapes, and there are especially many single pieces and non-standard products. The mold cost is high and the production cycle is long, which is not conducive to the production of single and non-standard parts.
2. The use of portable curve saw for drilling not only has poor cutting quality, dimensional accuracy is difficult to control, but also has high labor intensity, high noise, low production efficiency and more saw blades.
3. In recent years, some enterprises have introduced "multi position CNC punch" from abroad. Although it replaces punch punching, it is expensive and noisy. There are joint marks on the cutting surface, and the punch depends on foreign imports. Each multi position CNC punch requires at least 16 pairs of punches, each of which costs $2999, and the punches need to be replaced frequently, which is more uneconomical.
