A processing method and processing equipment for laser random texturizing roll surface

Abstract

The invention relates to a processing method and a piece of processing equipment for surfaces of disordered laser texturing rollers. The processing method comprises the following steps: adopting a random signal generator to control a pulse laser to generate the disordered pulse laser beams; processing a spiral line without overlapping tracks after focusing, wherein the helical pitch of the spiral line is smaller than the diameter values of laser speckles by 150%; and randomly changing the duty ratio and the frequency of the laser pulse beams by the pulse laser according to the random variables transmitted by the random signal generator. The processing equipment comprises a numerical control roller lathe, a laser and a laser processing head, wherein the processing head moves at a constant velocity along the lateral generatrix of the roller. The rollers which really meet the disordered requirements and steel plates which meet the disordered requirements can be manufactured by using the technical scheme. The surfaces of the rollers which are processed by the laser has the advantages of high hardness of the disordered texturing surfaces, low production cost and no pollution, so that the steel production of the rollers is greatly improved.

Description

technical field [0001] The invention relates to a processing method and processing equipment for texturizing the surface of a roll, in particular to a processing method and processing equipment for a laser random texturizing roll surface capable of producing various random texturing "spots". Background technique [0002] In the current industrial production of steel and non-ferrous metals, there are three commonly used methods for producing textured cold-rolled sheets. The first type uses shot peening technology to texture the rolls, and then chrome-plates their surfaces for rolling strips. ; The second category uses EDM technology to roughen the rolls, and then chrome-plates their surfaces for rolling strips; the third category uses laser technology to roughen the rolls and directly uses them for rolling strips. [0003] Because chrome plating pollutes the environment very much, most manufacturers omit the surface chrome plating process, directly use shot peening or EDM tec...

AI Technical Summary

Problems solved by technology

The current automotive panels and panels of high-end home appliances not only have requirements for the mechanical properties of the steel plate, but also have requirements for the appearance of the steel plate surface. The laser-ordered textured plate has a uniform appearance and arrangement of the textured "dots". Under the illumination of the light, the board reflects strongly at certain angles, which finally leads to different reflection effects when observing the board surface from different angles
