Roller laser unordered texturing device and method

Abstract

The invention particularly relates to a roller laser unordered texturing device and method. According to the roller laser unordered texturing device and method, a drag plate is movably arranged on a numerically-controlled machine tool and moves on the numerically-controlled machine tool in the axial direction parallel with a roller. An axial seat is movably arranged on the drag plate and moves onthe drag plate in a reciprocating manner in the axial direction parallel with the roller. A radial seat is movably arranged on the axial seat and moves on the axial seat in a reciprocating manner in the radial direction of the roller. A laser transmitter is mounted on the radial seat, and in other words, the laser transmitter can move in the axial direction and the radial direction of the roller.After the roller rotates, the transmitting end of the laser transmitter emits laser beams to the circumferential face of the roller in a timed manner, and the laser beams fall onto the circumferentialface of the roller perpendicularly so that texturing machining can be conducted on the roller. By means of the roller laser unordered texturing device and method, an unordered curve structure can beformed on the surface of the roller, and on the premise that the appearances of textured pits are not changed, unordered distribution of the textured pits on the surface of the roller is achieved.

Description

technical field [0001] The invention belongs to the technical field of roll surface texturing, and in particular relates to a laser random texturing device and method for rolls. Background technique [0002] Roll surface roughening technology is a key technology in the production of strips. The surface morphology of the rolls is copied to the surface of the strip through a certain rolling force, which can improve the anti-bonding performance of the rolled steel plate during the annealing process and smooth the surface of the strip. Excellent oil storage capacity and paint adhesion, and different texture indicators can be obtained through different roll texturing methods, thereby changing the surface properties of the steel plate. [0003] At present, the commonly used roll texturing processes mainly include shot peening, EDM texturing, laser texturing, etc., each of which has its own advantages and disadvantages: [0004] The shot peening process is simple and the texturing...

AI Technical Summary

Problems solved by technology

[0007] The disordered distribution technology of laser texturing roughly includes the following two types: obtaining disordered distribution by controlling laser pulses through circuit signals and obtaining disordered pulses mechanically. The surface of the roll is still one or more helical lines, and only when the textured points are extremely dense, it shows a disordered state, and the textured efficiency is low
