Reasonable design of control sequence of machine tool for fiber laser cutting machine
The propagation speed of light is greater than the gas transmission speed, and the cutting gas will lag behind during cutting or puncture. The fiber laser cutting machine starts to process and the cutting gas has not reached the required pressure or flow rate, resulting in contamination of the protective mirror.
The improvement methods of the fiber laser cutting machine are as follows:
①Modify the timing of light emission and air emission (cutting gas), and instruct air emission-wait for a certain time (gas waiting)-light emission-processing.
②The gas with a certain pressure (protective gas) is always given out during the whole processing process, and the processing sequence: Instruct the shielding gas-plate pretreatment (read processing data and define the origin, etc.)-instruct the puncture gas -Instruct the perforation stimulus light-Instruct the cutting gas-Instruct the cutting laser (cut contour)-End of contour cutting-Quickly locate to the next contour-Instruct the perforation gas-Instruct the perforation stimulus light-Instruct the cutting gas-Instruct the cutting laser (Cutting contour)-contour cutting end-cycle-cutting process end-shut off shielding gas-program end.
Reasonable cutting process data: Using reasonable cutting process data will prevent abnormal cutting from causing contamination of the cutting head.
Use qualified wearing parts: The selection of qualified wearing parts such as protective mirrors and O-rings will help the sealing of the cutting head.
The correct method of operation: According to the equipment supplier's use requirements, operate and use the machine tool correctly.
The correct maintenance method for fiber laser cutting machine
The fiber laser cutting machine ensures that the cutting head is clean and dry, and it is cleaned every day. Through the application of the above anti-pollution methods, the fiber cutting head The pollution condition of the inner optical lens is greatly improved. Practical applications show that as long as regular maintenance and attention to details are done, parts will not be cut and scrapped frequently, which prolongs the service life of the lens and improves the production efficiency of the equipment.
The entire servo drive system of the fiber laser cutting machine is composed of a drive mechanism, a numerical control system, a transmission mechanism, a guide mechanism, a feeding base, an executive clamp and a detection mechanism. The driving mechanism is composed of a servo motor and a precision reducer and accessories to match the transmission speed; the transmission mechanism includes a pulley, a timing belt, a transmission shaft, a rack and pinion assembly, a gear box, and a tensioning device; the guide mechanism is composed of a precision guide rail It is composed of auxiliary and guiding sliding seat; the guiding mechanism is equipped with a detection and anti-deflection detection mechanism, and the executive clamp is also equipped with a material detection mechanism. When the sheet is detected, the clamp is clamped, and the entire transmission system is controlled by the CNC system Execute the feeding work.
