Description

technical field [0001] The invention relates to the field of laser roughening treatment on the surface of rollers, in particular to a high-power laser roller surface multi-head roughening processing method and a device thereof. Background technique [0002] Textured steel plate has excellent stamping performance and surface coating performance, and is an important raw material widely used in automobiles, home appliances, electronics and light industry production. The key technology for the production of textured steel plate is roll surface texturing. Laser roll texturing technology is now Several texturing techniques used include shot peening, electric spark texturing and a practical and advanced texturing technique of electron beam texturing. [0003] At present, laser roll texturing technology is mainly divided into two categories: one is the use of gas CO 2 Laser CO 2 Laser texturing, the other is YAG laser texturing using solid Nd:YAG lasers. [0004] At present, the ...

Problems solved by technology

For example, "Laser processing device with controllable distribution of texturing points for roller surface texturing" (Patent No. ZL00264774.5), this laser processing device uses an acousto-optic Q-switched Nd:YAG laser as the processing light source, and its The disadvantages are: due to the limited service life of the YAG laser pump lamp, regular maintenance work such as replacement of the pump lamp is required, which affects production efficiency; in addition, the average power of the laser used in the device is low, the texturing effect is limited, and the production efficiency is very low. Low, difficult to meet the production needs of large steel mills

Although the device is designed to solve the problem of continuous production by using two lasers through optical path conversion to realize the alternate use of lasers in production, this design increases the complexity of the mechanical system, cooling system and optical path system, which is harmful to the reliability of the processing device. impact on durability
