Problems solved by technology

The biggest disadvantage of this device is that the energy of a single beam of light is too low to be textured
Another disadvantage is that the relative position of each beam of light is fixed, and the random distribution of micro pits cannot be realized.

Abstract

The invention provides a system and method for multi-beam synthesizing and focusing type roll surface texturing laser processing. The system comprises a machine tool, a multi-beam synthesizing and focusing device, a laser processing device and a control system, wherein the machine tool is used for driving a roll workpiece to rotate, the multi-beam synthesizing and focusing device is used for synthesizing more than two incident lights from different directions and gathering by a focusing assembly, the laser processing device is arranged on the machine tool and is used for driving the multi-beam synthesizing and focusing device to move along the roll workpiece in the axial direction and the radial direction, and the control system is used for controlling the rotating of the roll workpiece, the axial and radial movement of the multi-beam synthesizing and focusing device, and the distance among light spots, at the surface of the roll workpiece, of the multi-beam synthesizing and focusing device. The system has the advantages that the processing speed of laser texturing is improved; the easiness in generation of interference fringes is avoided; the setting of regular and irregular distribution parameters is convenient; more plurality of light beams are conveniently synthesized; under the condition of limitation by the speed of a main shaft, the processing speed of the laser texturing is improved; micro pits are coincided in a micro pit group, and the special texturing processing with large light spots and high energy density is realized by a plurality of low-power laser devices.

Description

technical field [0001] The invention relates to a discrete laser processing control technology, in particular to a laser processing system and a processing method for surface texturing of rollers with multi-beam light synthesis and focusing, which are suitable for the fields of laser texturing of cold rolls and the like. Background technique [0002] Cold-rolled thin steel sheets have the advantages of high thickness and shape accuracy, good surface quality, good mechanical properties, and thinner thickness, and are widely used. Cold-rolled sheet is divided into smooth sheet and textured sheet according to roughness. The textured plate is smoothed by the textured roller, and the surface morphology is copied from the surface of the textured roller, and the roughness is generally large. Compared with smooth panels, textured panels are widely used in industries such as automobiles, high-speed rail, aerospace, household appliances and food packaging because of their better elon...
