Focusing mirror active unordered device and method for roller laser-texturing lathe

Abstract

The invention discloses a focusing mirror active unordered device and a focusing mirror active unordered method for a roller laser texture lathe. A CO2 continuous laser or a YAG pulsed laser is utilized as an energy light source of roller texturing. A disturber is arranged on a focusing mirror support of a texturing head. Due to the use of the disturbing force generated by the disturber, the focusing mirror support is driven to change a tiny angle relative to a lathe support. Meanwhile, laser beams passing through the focusing mirror are subjected to angular change in random directions relative to the molded centerline of the laser; the laser beams passing through a chopper disk are scattered through the treatment of the chopper disk; and laser-texturing points in unordered distribution are generated on the roller surface so as to process sheet metals by using the textured roller. Due to the focusing mirror active unordered method, the matte effect of the surfaces of cold-rolled sheets can be achieved and the production efficiency of the roller laser-texturing lathe can be improved.

Description

technical field [0001] The invention relates to laser processing technology, in particular to a focusing mirror active disorder device and method using lasers for roll laser texturing machine tools. Background technique [0002] When using machine tools to produce cold-rolled metals, for example, when producing high-quality cold-rolled textured sheets, it is necessary to texture the working roll surface of the cold-rolled rolls, and then install them in rolling mills and tempering machines to produce the required cold-rolled thin metal sheets Come. In the prior art, laser texturing is also used to roll cold-rolled thin metal sheets, so that the processed metal sheets can make the small pits on the surface of the metal sheets not communicate with each other, so as to facilitate oil storage and storage during later stamping and forming. Capture metal debris, enhance its oil storage, prevent stamping scratches and ensure the deep drawability of the steel plate. In addition, wh...

Problems solved by technology

[0003] However, the current problem of laser texturing of rolls is that the texturing points on the rolls are all in order, which cannot meet the needs of users to produce matte cold-rolled sheets. This problem, in the application of CO 2 The laser roll laser texturing machine tool environment is particularly prominent; and in the roll laser texturing machine tool using YAG laser, although the effect of laser random texturing can be enhanced by changing the pulse frequency of the laser output, due to the pulse output of the laser The frequency is low, and the output laser can only be changed randomly in one dimension, and the disorder effect is not ideal
