Description

Roller part laser texturing device
Technical Field
The invention relates to the field of machine tool machining, in particular to a laser texturing device for a roller part.
Background
Textured cold rolled steel sheets with specific surface features have a wide range of applications in the manufacturing industry, particularly in the automotive and appliance industries. The roughened cold-rolled thin steel plate is rolled by a roller with roughened surface, and the deep drawing performance and the surface coating performance of the steel plate rolled by the roughened roller are greatly improved. The laser texturing technology is used as a texturing technology which is started for more than twenty years, and compared with the traditional shot blasting texturing and electric spark texturing technology, the laser texturing technology can obtain the best texturing effect and can prolong the service life of the roller. However, the two most important laser texturing technologies at present, namely YAG solid laser texturing and CO2 gas laser texturing, have the problem of low processing efficiency, and limit the application of the laser texturing technology in the mainstream metallurgical industry.
In order to solve the problem of low machining efficiency, some researchers now propose various solutions to improve the working efficiency. Nippon Nissan iron company has also attempted to roughen the roll surface simultaneously using multiple sets of lasers. However, due to the difference of the quality and the polarization state of light beams output by different lasers, the processing effect at different positions is different, the uniformity and the macroscopic appearance effect of the surface roughness are affected, and meanwhile, the investment of a plurality of lasers also greatly improves the equipment cost and the maintenance cost. There are also laser texturing apparatuses that use multiple heads. For example, the patent with publication number CN2882895 is named a high-power laser roller surface multi-head texturing processing device. The main principle is that a rotating polygon mirror reflects to enable laser to scan in a certain range, and a plurality of focusing mirrors are placed in the scanning range to focus the laser and then achieve multi-head texturing. However, in this process, because the focusing mirrors cannot be closely arranged and need to be fixed, laser always irradiates the outside of the focusing mirrors, which results in lower energy utilization rate, and because the scanning range is related to the angle corresponding to the surface of the polygon mirror, the larger the angle is, the larger the scanning range is, the larger the number of the placed focusing mirrors is, and the higher the processing efficiency is. However, the larger the angle, the smaller the number of edges of the polygon mirror, and the lower the number of scans when the polygon mirror rotates one turn, the lower the efficiency, and thus the processing efficiency cannot be improved significantly. In addition, in the processing process, one focusing lens forms one focusing point, more focusing lenses are needed to be added in order to form more focusing points, and the complexity of the system is increased.

Wherein the laser 1 is a high power laser including, but not limited to, CO2Laser, YAG laser, fiber laser. The laser texturing head 5 is shown in fig. 2, the polygon mechanism 501 comprises a polygon mirror and a high-speed motor for driving the polygon mirror to rotate, when the polygon mirror rotates clockwise, reflected light scans sequentially from top to bottom on the collimating mirror 502, the collimating mirror 502 collimates the light reflected by the polygon mirror, the size of the reflected light is required to ensure that the reflected light formed by scanning passes through the collimating mirror 502 in the rotating process of the polygon mirror, the front spectroscope 503 is composed of two reflecting mirrors 5031 as shown in fig. 3, an included angle between the two reflecting mirrors 5031 is an angle beta, and the function of the polygon mechanism is to divide the light collimated by the collimating mirror 502 into two parts uniformly, so that the first light splitting is realized. The split light respectively passes through the post-splitter 504 and the focusing head 505 in sequence, each post-splitter 504 is composed of two identical reflectors 5041, as shown in fig. 5, a certain angle θ is formed between the two reflectors 5041, the angle can be controlled to change, so that two beams of laser light which are not parallel and have a certain angle are formed after the laser light passes through the post-splitter 504, secondary light splitting is realized, two focusing points are formed after the laser light passes through the splitting laser light beam and passes through the focusing lens 5062, the distance between the focusing points is f θ, and f is the focal length of the focusing lens. Meanwhile, as shown in fig. 4, the mirror 5041 of the rear beam splitter 504 is also disposed on the angle shifter 5042, and the output of different focusing point arrays can be realized by adjusting the inclination angle of the mirror 5041, wherein when the inclination angle of the mirror 5041 is 0, the focusing points are arranged in a line, and when the inclination angle of the mirror 5041 is not 0, the focusing points are arranged in a zigzag state as shown in fig. 2.
