Embodiment Construction

[0028] The present invention is described in detail below in conjunction with accompanying drawing:

[0029] In order to realize the random distribution of laser texturing, the scheme proposed in this embodiment is shown in Fig. 2, Fig. 3, Fig. 7 and Fig. 12 . The roughening processing of the irregular roughening points on the surface of the roll is realized by a pseudo-random deflection device and a random delay device. That is to say, in the controllable distribution laser texturing equipment, a device whose control amount changes according to a pseudo-random signal is added to make the texturing points randomly distributed. Therefore, this equipment is also called a roller surface texturing laser processing system with controllable random distribution of texturing points.

[0030] The overall structural schematic diagram of this embodiment is the same as that shown in Figure 2. The equipment consists of three parts: the head of the machine tool, the bed of the machine tool...

Abstract

A laser machining system for roughening the surface of roller in such manner that the roughened dots are irregularly deflected is composed of a machine-tool for driving the roller to be machined to rotate, a laser machining unit moving axially along said roller, and a pseudo-random deflecting mechanism consisting of pseudo-random signal generator, the driver of the motor for making lens to vibrate, and the lens vibrating assemblage comprising lens vibrating motor and reflector. Its method is also disclosed.

Description

technical field [0001] The invention relates to a laser processing equipment and a processing method for roughening the surface of rollers, in particular to a laser processing equipment and a processing method for roughening the surface of rollers capable of processing irregular textured points. Background technique [0002] YAG laser texturing equipment is a cold roll laser processing equipment researched and developed by the Institute of Mechanics, Chinese Academy of Sciences in the 1990s, such as: Chinese patent number: ZL 92113223.9, name: "High repetition frequency modulation multi-pulse YAG laser engraving system and processing method "; Chinese patent number: ZL94220848.X, name: "Laser processing equipment for surface roughening of rolls". Figure 1 is a schematic diagram of the overall structure of the device. The equipment uses high-power laser pulses with high repetition frequency to act on the surface of the roll, and produces countless strengthened micro-pits (te...
