First of all, the fiber laser head of the plate and tube integrated laser cutting machine has an adjustable focusing system. When cutting the plate, the position and angle of the focusing mirror are adjusted to a state suitable for plane cutting, which can form a precisely focused high-energy laser beam on the surface of the plate to achieve efficient cutting. When switching to the tube cutting mode, the focusing system will automatically adjust the position of the focusing mirror according to the tube diameter, wall thickness and other parameters of the tube to ensure that the laser beam can be focused on the cutting part of the tube to ensure cutting accuracy. This adjustable focusing system provides a basic guarantee for different cutting modes.
Secondly, the optical path switching device of the laser head plays an important role. The device can quickly change the transmission path of the laser through precise optical elements and mechanical structures. In the plate cutting mode, the laser is directly transmitted to the cutting area along a specific optical path; when it is necessary to switch to the tube cutting mode, the optical path switching device quickly acts to guide the laser to a direction suitable for tube curved surface cutting, avoiding energy loss and offset of the laser during transmission, thereby achieving stable output of laser energy when the cutting mode is switched.
Furthermore, the coordination of the motion control system is the key. The high-precision motion control system equipped with the fiber laser head can accurately control the movement of the laser head in three-dimensional space. When cutting plates, the laser head mainly moves and cuts on a two-dimensional plane; when switching to the tube cutting mode, the motion control system controls the laser head to move in a circumferential and axial direction according to the shape and cutting requirements of the tube. Through the precise control of the motor, guide rail and other components, the laser head can be quickly and stably positioned and moved in different cutting modes to ensure the continuity of the cutting process.
In addition, the intelligent identification and automatic parameter adjustment functions are indispensable. The control system of the plate and tube integrated laser cutting machine can identify the cut material through the sensor to determine whether it is a plate or a tube. When the material type changes, the system automatically calls the corresponding cutting parameters, including laser power, cutting speed, auxiliary gas pressure, etc., and transmits these parameters to the fiber laser head. The laser head quickly adjusts the working state according to the new parameters, thereby realizing the rapid switching of the cutting mode, without the need for manual tedious parameter settings, and improving the processing efficiency.
At the same time, the modular design allows some components of the laser head to be quickly replaced. In response to the different needs of plate and tube cutting, some key components of the laser head adopt modular design. For example, specific nozzles and protective lenses may be required when cutting tubes. When switching modes, operators can quickly replace these modular components to adapt to the special requirements of tube cutting. This modular design not only facilitates operation, but also extends the service life of the laser head to a certain extent and reduces maintenance costs.
In addition, the fast-response cooling system also supports mode switching. Whether it is plate or tube cutting, the plate and tube integrated laser cutting machine laser head will generate heat during operation, and excessive temperature will affect the performance and life of the laser head. The efficient cooling system can quickly adjust the temperature of the laser head when the cutting mode is switched, ensuring that the laser head can maintain a stable working state under different working conditions. Even in the case of frequent switching of cutting modes, the cooling system can quickly adapt to changes and provide reliable temperature protection for the laser head.
Finally, the advanced software control system integrates all the above functions. The software system processes and analyzes various data through algorithms to coordinate the work of various components of the laser head. During the switching of cutting modes, the software system can accurately control the collaborative operation of the focusing system, optical path switching device, motion control system, etc. to achieve seamless connection. At the same time, the software also has the characteristics of friendly operation interface and high degree of visualization. Operators can quickly switch between plate and pipe cutting modes through simple operation instructions, which greatly improves the usability and production efficiency of the equipment.
