Macroscopic analysis of 3d laser cutting technology
3D laser cutting machine, fiber laser, robot system, servo cutting system together, such as high quality issued by the fiber laser, laser through the optical fiber transmission of laser cutting head, a collimating and beam expander, focused on the realization of the workpiece after cutting, because the fiber laser has good beam quality, high power density, the characteristics of flexible transmission which can well realize the laser three-dimensional cutting, this system has high photoelectric conversion efficiency, comprehensive use of low cost, high reliability, easy operation, free maintenance, long service life, small volume.
Cutting characteristics of
3D laser cutting takes advantage of the flexible and fast action performance of industrial robots. According to the size of the cutting workpiece, the robot can be installed or inverted according to the size of the user, and the robot can be programmed for instruction or off-line for different products and different tracks. The irregular workpiece can be 3d cut through optical fiber laser cutting head.The laser beam is transmitted to the cutting head by optical fiber, and then the focusing system is used to focus, which can be used for multi-directional cutting of various THREE-DIMENSIONAL metal plates.
According to the thickness of the metal plate, the power of the selected fiber laser is also different.The different power laser is equipped with different cooling system to ensure the normal operation of the laser.At the same time, according to the working radius of the manipulator and the size of the workpiece processed by the customer, the appropriate length of optical fiber transmission laser should be selected to meet the cutting requirements.
Working mechanism of 3D laser cutting is compared with 2d laser cutting. 3d laser cutting requires constant adjustment of the laser cutting head posture to ensure that the laser cutting head is always perpendicular to the surface of the workpiece, so as to obtain excellent cutting quality.In actual production, 3d laser cutting programming requires 3d modeling of parts first, and then importing 3d programming system generation path, and manual adjustment is required according to the features of parts and tooling, so as to avoid collision of cutting head, complicated operation and heavy workload.
(1) Good flexibility, can adapt to different shape of the workpiece cutting processing.
(2) high precision, can meet the aluminum alloy emu, stainless steel subway and other products manufacturing precision.
(3) high economic efficiency, can replace the traditional manufacturing process of trimming die and punching die, its process steps are simple, short manufacturing cycle, cutting speed, small slit width, high processing quality, can greatly reduce the cost.
Range of application
3D 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, glasses production, aerospace, medical instruments, instruments and other industries.Especially in the sheet metal processing industry has replaced the traditional way of processing, by the industry users of the favor.
3D laser cutting technology, as a laser application technology, has been more and more widely used in the automotive industry: automotive parts, automotive body, automotive door frame, automotive trunk, automotive roof cover and other aspects.It can replace the traditional processing method, reduce the mold investment, greatly shorten the development cycle of automobile manufacturers and parts suppliers, improve the processing efficiency and the precision of cutting workpiece, reduce the production cost, and is a powerful tool for automobile manufacturers and parts suppliers to improve their competitiveness.
Because the cutting head of 3d laser cutting machine is equipped with capacitive sensor, it can automatically adapt to the shape of parts, and always keep a certain distance from the parts for cutting, so in the case of no drastic changes in the surface of parts, only the two-dimensional programming system of 3D laser cutting machine can meet the production needs.
