The planning and management industry of the fiber laser cutting machine system
The fiber laser cutting machine is used to deal with the problems of inconsistent cutting section of steel pipe cutting in industrial production, low accuracy and low cutting compliance. According to the advantages of planetary layout, planetary cutting is used as the main action to complete the control of cutting chips. And achieve the result of flat section. Connect fixed-length cutting and quantitative feed request, adopt the full servo direct drive plan, and use the electronic gear to control the pulse equivalent to ensure the accuracy to meet the industrial production requirements. The entire system is controlled by the PLC, and the sixth is completed. Axis full servo control. The system includes three control modes: active, manual and semi-active. Experience touch screen communication to simplify the maneuverability of the system. This system is reliable, clear and crisp, naive, and has high cutting obedience and strong suitability. Stainless steel has become a material for automobile exhaust pipes with its convex resistance to high temperature fatigue and acid and alkali corrosion. Under the conditions of meeting the process requirements, cutting long steel pipes into fixed-length short steel materials has become a key material in the production of steel pipe derivatives. The main joints.
Currently, China's cutting methods for thin-walled stainless steel pipes are still unconcerned. Cutting skills must include grinding wheel cutting, laser cutting, wire cutting, single-blade coil cutting, etc. Grinding wheel cutting is widely used in steel pipe cutting, but it is difficult to complete high-precision and high-obedience cutting; although laser cutting can complete high-precision and high-obedience, it is inevitable because of the high cost of high-powered baldness and high temperature during cutting. The dangerousness of the steel pipe is not suitable for general industrial production; wire cutting can complete high-precision cutting, but the cutting obedience is low; single-blade coil cutting, because the steel pipe itself is in a torsion state, it is difficult to guarantee the cutting accuracy during cutting The double-knife symmetrical planetary cutting mentioned in this article can not only complete high-speed and high-precision cutting, master cutting chips, but also cost-effectively, which is suitable for general industrial production line production.
PLC, as a controller specially planned for industrial conditions, has the characteristics of careful layout, small size, light weight, low power consumption, and strong anti-interference ability. It must be applied to separate production, process production, etc., which occupies an insignificant position in the development of China's industry. This article applies PLC to the six-axis control system of fiber laser cutting machine, and completes independent and active control of the actions of each axis. Not only completed the multi-axis naive action, satisfied the cutting request, but also greatly improved the obedience of the work. The system adopts the servo direct drive work layout, which has the advantages of simple layout, positioning, and easy control. It not only guarantees the reliability of the work, but also can Complete higher cutting accuracy.
The machine layout of the fiber laser cutting machine system is mainly composed of feeding and cutting sides. The feeding side includes a feeding screw and a feeding clamp; the cutting side includes a front clamp and The cutter head that has been cut. The feed and front clamp adopt the active centering clamp plan to ensure that the front clamp and the feed clamp are aligned when the steel pipe is actively clamped. The cutting plane adopts the double-knife symmetrical planetary plan, that is, rotation—linear action— Revolution: Let the blade rotate first, the feed motor completes the linear feed of the blade, and undergoes the rotation of the cutter head to mobilize the blade revolution to complete the cutting. Before the equipment is operated, the two tools are calibrated to a uniform plane, and because the two blades are cutting at the same time, Compared with a single blade, it can not only obtain a superior cross-section, but also improve cutting compliance to a certain level.
