u200bWhat are the functions of fiber laser cutting machine
Fiber laser cutting machine involves the study of light, machine, electricity, gas, etc. It is a complicated system. In addition, the laser cutting process itself is an extremely complicated process of physical and chemical changes, affecting many aspects. Because of the limited degree of research and experimental premises, this article has some shallow points. The development of the laser cutting machine is an eternal and arduous process, and it requires co-operation in many aspects. This article believes that the fiber laser cutting machine can be continuously studied and explored from the following aspects.
(1) Research and development of fiber laser cutting machine. Research and development of fiber laser cutting machine, the promotion of CO2 fiber laser cutting machine power and the improvement of beam mode.
( 2) Research on optical lens and laser cutting first parts of the components and processing technology in the optical path system.
( 3) The study of nozzle layout adopts numerical simulation techniques to explain the flow field, and understand the connotation mechanism of the influence of nozzle layout on the cutting-assisted gas flow field diffusion. This matter is related to thick plate cutting. Tension.
( 4) The study of laser cutting process parameters establishes an expert system of various materials, laser power, help gas, cutting rate, core position and other parameters, making the processing system intelligent
When the laser beam first penetrates the steel plate and enters the part to cut the appearance of the part, its cutting rate will have a big change in the vector deflection, that is, the 90° twist of the vector deflection will change from perpendicular to The deflection of the tangent line of the cut appearance turns to coincide with the tangent line of the cut appearance, that is, the angle between the tangent line and the appearance is 0°. This will result in a relatively rough cutting surface under the sublime cutting surface of the processed material. This is important because in a short time, the vector deflection of the laser beam in the movement changes very quickly. Therefore, it is necessary to pay attention to this aspect of the environment when accepting laser cutting parts. Normally, when there is no requirement for roughness on the cut and cut surface of the planned part, it is possible to avoid manual punishment during the laser cutting programming, and let the master software automatically generate the puncture point; however, when the cut surface of the part to be processed has a higher roughness When making a request, you must pay attention to this question. Usually, you need to manually adjust the starting position of the laser beam when programming the laser cutting program, that is, manually grasp the puncture point. It is necessary to move the puncture point that originally occurred in the laser method to a reasonable position in order to meet the requirements for the appearance accuracy of the processed parts.

Execute fully automatic feeding
The feeding is executed by the touch screen menu. After receiving the loading request signal, it is controlled by the logic in Mitsubishi PLC to automatically execute the selection of the rack level, the reclaiming rack, the loading to the zero level, and the operation to the unloading station. Finally, the signal to complete the loading is sent to the laser control system.
PLC logic control programming
Programming is carried out through FX-3U Mitsubishi PLC to design the working mode of the three-dimensional library to meet the requirements of the feeding part.
The structure of the automatic loading and unloading facility of the fiber laser cutting machine
The frame, the finished product sorting table, and the fork suction device constitute an automatic loading and unloading system.
Suction process of fiber laser cutting machine
The specific suction process: the plate is sent from the three-dimensional warehouse to the loading table; driven by the motor, the suction device moves horizontally to Loading table; with the cylinder downwards, the vacuum suction cup falls on the plate to be processed; the plate is sucked by the suction cup; with the cylinder upwards, the suction device moves to the exchange table; with the cylinder downwards, the plate falls on the work table; Through the release operation, the plate is placed on the worktable by the suction cup, and the loading is completed.
Fork material process
Fork, slider, bracket, elevator are the main parts of fork material. After the processing is completed, the fork material device is driven by the motor to move onto the plate. When the cylinder moves downward, the plate is lifted by the fork teeth. When the cylinder moves upward, the plate is sent to the sorting table under the drive of the motor. Separate the plate and the tines, and then the cylinder moves upwards, and the blanking ends.
Sorting table
The finished plates are pulled out from the sorting table, and workers sort the finished products.
The gantry-mounted fiber laser cutting machine is the structure of the laser cutting machine, imported high-precision linear guide, precision rack and pinion and screw to ensure the accuracy of positioning and repeatability. The special numerical control Fagor system for the control system, the laser is YLS-2000 manufactured by IPG, and the non-contact integrated sensor constitutes the follow-up system. This kind of laser cutting machine has high precision and quick response.
After the plate to be processed is placed on the exchange table by the automatic loading and unloading facility, the material signal is received by the CNC system, and then the plate is automatically run to the laser cutting head to cut the processed plate. After finishing the processing, the fork device and the cylinder execute the cutting action.
To sum up, at the current stage of fiber laser cutting machine, from the current situation of my country's application of FMS, fiber laser cutting machine sheet metal FMS has been successfully applied. Practical experience includes: based on CIMS ideas, flexible use of foreign advanced production models, and based on national conditions and factory conditions, to promote the development of unit technology with CIMS as the key core, to achieve a unique promotion of upper-level construction through bottom-level construction, and to complete each in turn. System link. At the same time, it actively organized talent education and training activities to improve the overall strength of the unit, supplemented by specific management, scientifically introduced advanced equipment, and steadily improved the level of the unit, laying a solid foundation for CIMS. The related flexible production line of FMS laser cutting machine can just further promote the rapid development of sheet metal processing and manufacturing, and it is worth strengthening research efforts.
