Method and device for real-time control texturing of cvc roller fiber laser focal length

Abstract

The invention discloses a CVC roller optical fiber laser focal length real-time control texturing method and device. According to the method, by adjusting the distance between a light outlet of a collected laser texturing head and the surface of a roller in real time, the focal length of lasers falls on the surface of the roller to be machined all the time, it is ensured that the energy of lasers borne by the surface of the roller is the same, and therefore the uniformity of roughness of the roller surface of the roller is improved. The device comprises a small supporting plate capable of moving in the X-axis direction on a numerical control machine tool. A supporting platform is fixedly installed on the small supporting plate and provided with a working slide table capable of moving in the X-axis direction. A drive motor is arranged at one end of the working slide table. The laser texturing head capable of emitting lasers in the X-axis direction is arranged on the working slide table. A distance sensor is arranged on the laser texturing head. The drive motor, a focal length real-time controller and a signal processor are fixedly installed on the supporting platform.

Description

technical field [0001] The invention relates to a roll surface roughening treatment technology, in particular to a method and a device for real-time controlling texturing of a CVC roll optical fiber laser focal length. Background technique [0002] Steel plates and strips can be randomly cut, welded and riveted as required, and can also be bent and stamped, so they are widely used in various sectors of the national economy. Especially with the rapid development of the automobile and household appliance industries, the requirements for the shape and straightness of the strip are getting higher and higher. [0003] Regarding the shape and flatness of strip products, several major industrialized countries in the world have conducted long-term discussions and researches, and successively developed technologies such as HC, CVC and UPC. In 1984, CVC technology was first launched by German Schroman SMS Siemag. With its unique features, it has shown its prowess in the field of hot ...

Problems solved by technology

However, there are defects in these two methods: before using the first method for texturing, each roller will measure the roll surface curve, and the workload is very large; after using the second method for texturing, the roughness of the roll surface will decrease. Changes with the curve of the roll surface, the roughness is not uniform enough
