Laser Cutting to Build High Quality Elevator

The traditional cutting methods include flame cutting, plasma cutting, water knife cutting, wire cutting and punching, etc. Laser cutting, as a newly developed technology in recent years, irradiates the laser beam with high energy density on the workpiece to be processed, causes local heating and melting, and then uses high-pressure gas to blow off the slag to form a slit.

The so-called three-dimensional optical fiber laser cutting machine is an advanced laser cutting equipment with flexible multi-angle and multi-direction cutting for metal sheets of different thickness by special optical fiber laser cutting head, high precision capacitive tracking system, optical fiber laser and industrial robot system.

At present, three-dimensional laser cutting is widely used in sheet metal processing, metal processing, advertising production, kitchen utensils, automobiles, lamps, saw blades, elevators, metal crafts, textile machinery, grain machinery, aerospace, medical equipment, instrumentation and other industries. In particular, it has replaced traditional processing methods in the sheet metal processing industry and is favored by industry users.

In the 1990s, the whole machine factory basically used multi-station punching to process plates. Now for safety reasons, the current elevator components are basically made of metal materials. Now the development trend of elevators is mainly high-speed elevator technology, intelligent control, and efficient cleaning processing. Later, with several world-famous brand elevators, imported laser cutting machines were introduced in domestic wholly-owned or joint ventures, and laser cutting machines began to be used in the domestic elevator industry. At the beginning of the 21st century, with the emergence of domestic laser cutting machine manufacturers, the habit of relying only on imports was broken, and the expensive price was also reduced a lot. Domestic general machine companies and accessory companies successively purchased laser cutting machines.

Why does the robot 3D laser cutting machine have different cutting quality when cutting the same workpiece? The effect of cutting straight line or large side is good, but the effect will be much worse when cutting corners or small holes. In severe cases, there will be scraping phenomenon? The mechanical structure of the shaft manipulator is a six-axis series structure, and the speed reducers of each of the six axes have precision errors. When the manipulator takes a straight trajectory, the angle of the six-axis transformation is small, so the quality of the cutting is good, and the quality of the circular trajectory or some of the large-angle transformations is significantly reduced. Why the different posture cutting quality has different effects is due to the problem of the force arm and the load, and the different lengths of the posture arm are different, so different cutting effects will occur.

The application of advanced optical fiber laser cutting machine improves the quality of domestic elevator manufacturing. Elevator manufacturers also realize that only by improving the automation and intelligence of equipment, can they flexibly and freely respond to various production tasks and enhance production capacity.

The processing cycle is short. There are many kinds and few quantities of sheet metal parts in elevator industry, many of which need to be determined according to customers'requirements. Due to the limitation of tonnage and dies, some sheet metal parts can not be processed or the production cycle of dies is long, which leads to longer production cycle. Moreover, the programming is relatively complex and the requirements for operators are relatively high. The advantages of flexible processing of optical fiber laser cutting machine have been brought into full play and the cost of product development has been reduced.

The cutting effect is good. Stainless steel decorative plate, surface finish requirements, processing lines to be smooth and smooth, beautiful. Multi-position punch processing is easy to affect the surface smoothness of sheet metal. Laser processing means have no mechanical stress, which avoids the deformation in the cutting process, improves the quality of elevators, upgrades the product grade, and improves the core competitiveness of enterprises.

High processing flexibility. With the improvement of people's aesthetic level, the fancy of the products has also increased, and the variety of products has increased, but the quantity is not large, and the outline is complex, and ordinary processing methods cannot be realized. Laser cutting automation and high degree of intelligence can cope with the processing of various shaped workpieces, effectively reducing the labor intensity of operators and optimizing the production process.

Adopting laser cutting process, the whole machine has good rigidity, stable performance, stable operation, fast speed, fast acceleration, high precision and high processing efficiency. It can meet the cutting requirements of various metal sheets such as carbon steel and stainless steel, and is an ideal choice for medium and thin sheet processing. It is suitable for cutting elevator steel plates.
