Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to a laser cutting device and a cutting method thereof. Background Art

[0002] Laser cutting is a process in which a laser beam concentrates its energy at a focal point through a focusing lens and generates high-density energy. A light spot is formed when it reaches the surface of the material. The material absorbs heat at the light spot and quickly melts to form a molten material or even vaporizes. The molten material flows out from the incision under the dual effects of gravity and the dynamics of the auxiliary airflow, thereby achieving material removal. As the laser beam moves, non-contact, high-speed, and high-precision cutting is achieved.

[0003] However, the existing laser cutting devices do not have automatic cleaning devices. When there are impurities such as oil, rust, dust, etc. on the surface of the material to be cut, the laser beam acting on these impurities will produce uneven energy absorption and scattering. For example, when cutting metal sheets, if there is a thick layer of rust on the surface, the energy actually acting on the material at the focal position of the laser beam will change, and the cutting line will easily deviate, which cannot meet the high-precision cutting requirements.

[0024] The present invention provides a laser cutting device, which has the following beneficial effects:

[0025] 1. Through the setting of the cleaning mechanism, the surface of the material to be laser cut can be cleaned by spraying water. After the oil, dust, oxide layer and other impurities on the surface of the material are cleaned, the laser beam can accurately act on the pure surface of the material. No additional impurities will be attached to the cleaned surface of the material during the laser cutting process, avoiding chemical reactions between impurities and materials and changing the microstructure and chemical composition of the cut surface, so that the quality of the cut surface meets high-quality industrial standards.

[0026] 2. Through the setting of the grinding mechanism, the surface of the material to be laser cut can be polished. Surface grinding can make the surface of the material smoother and flatter. The flat surface helps to maintain the accuracy of the laser focus position, making the cutting line straighter and more accurate. It is very important for the manufacture of precision mechanical parts and other occasions with extremely high dimensional accuracy requirements.

[0027] 3. The setting of the water spray head can prevent a large amount of dust from being generated during grinding. During the cleaning process, especially when cleaning materials that are prone to dust, water spraying can suppress the generation of dust. When the surface of the material is ground and cleaned, without spraying water, the stone powder generated by grinding will diffuse in the air, which will not only harm the health of the operator, but also pollute the surrounding working environment. Water spraying can reduce the spread of dust in the air, maintain the air quality in the workplace, and also meet environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS
