The laser cutting machine is mainly used in the household appliance manufacturing industry to carry out laser cutting production and processing for cold rolled steel plate parts in the installation of electrical components of a part of profile sheet metal parts and their complete sets of equipment. At present, many electrical plants have adopted this new technology to improve product quality, reduce product costs, ease labor efficiency, improve the traditional plate processing technology, and receive good production and manufacturing economic benefits.
Application of laser cutting machine in household appliance manufacturing industry
Current status of sheet metal processing technology in household appliance manufacturing industry
In the household appliances, the parts produced and processed by metal sheet materials basically account for about 30% of all commodity parts. The traditional cutting, corner cutting, punching, blank pressing and other processing technologies are outdated and immediately endanger the product quality and cost. The reason analysis gives:
1. Many abrasives must be used for production and processing of traditional high-speed punch. The spare parts of household appliances have many punching specifications and different appearances, and there are many spare parts and non-standard goods. Abrasive engineering cost is high, and the manufacturing period is long, which is unfavorable to the production and manufacturing of parts and non-standard parts.
2. The hand-held curve saw is selected for drilling, which not only has poor wound quality, difficult to control the specification precision, but also has high labor efficiency, high noise, low productivity and high consumption of woodworking saw blades.
3. In recent years, some companies have introduced “multi fixture CNC machine tools” from overseas. Although they have replaced high-speed punching machines, they are expensive, noisy, and have contact marks on the breaking surface. Punching needles are imported from abroad. Each CNC machine tool must have at least 16 pairs of punches, each of which costs 3000 US dollars, and the punches must always be replaced, which is not economic development.
Specific advantages of laser cutting machine in the application field of household appliances
Optical fiber laser cutting is a new and high-tech technology that has been developing in recent years. Compared with traditional cutting processing technology, it has higher laser cutting precision, lower surface roughness, higher raw material utilization rate and productivity and other characteristics. Especially in the meticulous laser cutting industry, laser cutting machines have incomparable advantages over traditional laser cutting. Optical fiber laser cutting is a non touch, high-speed and high-precision laser cutting method that focuses kinetic energy on fine indoor space and uses dense kinetic energy.
In the whole process of production and manufacturing of household appliances, there are a lot of sheet metal parts and components, which are complex in appearance and have a large coefficient of difficulty in processing technology. In addition, in the whole process of production and processing, there must be a lot of work clothes and abrasives to ensure the production and processing quality. In the household appliance manufacturing industry, the fiber laser cutting technology can not only reasonably solve the problem, but also has the necessary efficacy and use value to improve the production and processing quality of steel parts, save the production and processing stages and production and processing costs, reduce the production cycle time of goods, reduce workers and production costs, and greatly improve the production and processing efficiency.
