As an advanced process that combines cold bending and laser cutting, Cold Bending Laser Cutting can achieve high-precision processing of complex shapes.
1. High-precision laser cutting
Laser beam characteristics: The laser cutting machine uses a high-energy-density laser beam for cutting. After focusing and collimation, the laser beam can form a high-energy-density light spot at a very small focus. When this light spot is irradiated on the surface of the material to be cut, it can instantly melt or reach the ignition point, thereby achieving precise cutting of the material.
Control system: The control system of the laser cutting machine is usually composed of a computer, a motion controller, a graphics processor, and a sensor. These components work together to ensure that the laser beam moves precisely along the preset trajectory, thereby achieving high-precision cutting of complex shapes.
Focus position control technology: The smaller the focal depth of the focusing lens, the smaller the focal spot diameter, so it is very important to control the position of the focus relative to the surface of the material to be cut. High-precision focus position control technology can ensure that the laser beam always maintains a stable focus position during the cutting process, thereby improving cutting accuracy.
2. Cold bending aid
Preforming: Before laser cutting, the cold bending process can perform preliminary bending or forming on the material. In this way, the originally flat material can be processed into a workpiece with a certain shape and curvature, providing a better processing basis for subsequent laser cutting.
Reduce processing difficulty: Through cold bending, some complex shapes can be achieved to a certain extent in the material preforming stage, thereby reducing the processing difficulty and complexity during the laser cutting process.
3. Three-dimensional cutting technology
Three-dimensional cutting method: For complex three-dimensional shapes formed by cold bending, the laser cutting machine can use three-dimensional cutting technology for processing. By adjusting the angle and position of the laser cutting head, and using advanced cutting software and algorithms, the laser beam can be precisely cut along the contour of the three-dimensional shape, thereby achieving high-precision processing of complex shapes.
Cutting fixtures and positioning plates: In order to improve the accuracy and efficiency of three-dimensional cutting, special cutting fixtures and positioning plates can be made. These tools can ensure that the workpiece maintains a stable position and posture during the cutting process, thereby reducing cutting errors and improving processing quality.
In summary, Cold Bending Laser Cutting technology can achieve high-precision processing of complex shapes through high-precision laser cutting, cold bending forming assistance, three-dimensional cutting technology, and special cutting fixtures and positioning plates. This technology plays an increasingly important role in modern manufacturing and provides strong support for product innovation and quality improvement.
