Description

TECHNICAL FIELD

[0001] The utility model relates to laser cutting machine technical field, specifically is a kind of laser cutting machine with material lifting function. BACKGROUND

[0002] As an advanced cutting equipment, the working principle of laser cutting machine is to focus the laser emitted from the laser into a high-power density laser beam through the optical system. When the laser beam irradiates the workpiece surface, it will make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam will blow away the melted or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material finally forms a cutting seam, realizing the cutting purpose. In many industries, such as metal processing, automobile manufacturing, electronic equipment production, etc., laser cutting machine has been widely used due to its high cutting precision, fast speed, good cutting quality and other advantages.

[0003] In the laser cutting process, it is crucial to ensure that the laser focal point maintains a suitable distance from the workpiece surface. Through the material lifting function, the distance between the material and the laser head can be conveniently adjusted, ensuring that the laser is focused at the ideal position, thereby obtaining the best cutting effect and quality. Especially for some uneven surface materials, the material lifting function can maintain a constant distance between the laser head and the material surface by automatically adjusting the height, effectively ensuring the cutting precision.

[0004] However, frequent height adjustment will inevitably produce slight vibrations, which may cause the material to shift. Once the material shifts, the relative positional relationship between the laser beam and the material is broken, and the cutting path deviates, which not only affects the smooth progress of the cutting process, but also causes cutting failure, resulting in material waste and reduced production efficiency. In order to avoid the material from shifting during frequent lifting and ensure the smooth progress of the cutting process, we propose a laser cutting machine with material lifting function. SUMMARY
