Problems solved by technology

[0009] 1. Although the laser textured pits on the surface of the roll are very shallow, for large-area textured cold-rolled steel sheets, it can still be clearly felt that there is a uniform distribution of cold-rolled steel sheets along the length direction (rolled along the circumferential direction of the roll). Straight line, but there is no obvious straight line distribution in the transverse direction of cold-rolled steel plate
[0010] 2. It is easy to form a strain in the length direction of the cold-rolled steel plate, forming a very thin linear scratch along the length direction of the cold-rolled steel plate

Embodiment 1

[0055] Example 1: Such as figure 2 Shown is a specific implementation of the laser texturing device for the surface of a roll with a focused spot swing of the present invention. It includes a laser 1 and a numerically controlled machine tool 3, the numerically controlled machine tool 3 adopts a conventional XL9 type numerically controlled machine tool, and its bed body A work platform 12 driven by a translational guide rail 303 and a roll shaft 301 and a top 302 for mounting the roll 13 are provided, and the roll shaft 301 and the top 302 are parallel to the translation guide 303. The working platform 12 is equipped with a polygonal scanning mechanism 4 and an integrated focusing mechanism. The integrated focusing mechanism consists of K=4 integrated focusing heads (respectively the first integrated focusing head 601, the second integrated focusing head 602, and the third integrated focusing head). Head 603 and the fourth integrated focusing head 604); and the laser 1 uses high...

Embodiment 2

[0065] Example 2: Such as figure 2 As shown, this embodiment provides the focusing spot swing type roller surface laser texturing processing device, its external structure is the same as that of embodiment 1, but the difference is that it uses the first reflection in the polygon scanning mechanism 4 of embodiment 1 The type focusing lens 403 is replaced with the first transmission type focusing lens 404, and the internal structures of the four integrated focusing heads 601, 602, 603, and 604 are all redesigned at the same time. Specifically, taking the first integrated focusing head 601 as an example, in this embodiment, a second transmission type focusing lens 7 and N=3 closely arranged focusing lenses 901, 902 arranged opposite to the second transmission type focusing lens 7 are arranged inside. 903, such as Figure 8 Shown ( Figure 8 The high-speed motor 409 and the four beam splitters 405, 406, 407, and 408 connected to the side of the polygon mirror 402 are omitted. The ...

Abstract

The invention discloses a swinging-focal spot roller surface laser texturing method, which is characterized in that: continuous laser beams output by a high-power continuous laser are focused on a certain working face of a prism which is rotating at a high speed and has misaligned rotation and prism axes; K paths of pulse laser beams which are transmitted in a direction vertical to the rotation direction of the prism and quickly swing are formed by the scanning and splitting of the prism; and the K paths of pulse laser beams are focused by K integrated focusing heads to produce K*N focal spots which swing quickly along the length direction of a rotating roller respectively so as to texture the surface of the roller at the same time to form irregular textured spot distribution of alternately arranged K*N non-spiral scanning line-point matrixes, wherein K is more than or equal to 1, N is the number of focal spots output by a single integrated focusing head correspondingly, and k*N is more than or equal to 2. When the roller processed by the method rolls a steel plate, scratches in the length direction of the steel plate are avoided, and the rolling quality of the steel plate is improved.

Description

Technical field [0001] The invention belongs to the field of laser texturing processing on roller surfaces, and in particular relates to a laser texturing processing method and device for the surface of rollers with a focus spot swing type. Background technique [0002] The texturing cold-rolled steel sheet with special surface morphology is widely used in the manufacturing industry, especially in the automobile and home appliance industries. Textured cold-rolled steel sheet is rolled by a roll whose surface has been textured. Therefore, the surface morphology of the texturized roll has a great influence on the process performance of cold-rolled steel sheet such as deep drawing and coating. [0003] In order to ensure that the cold-rolled steel sheet has excellent shape, deep drawability, elongation and coating performance, in the production process of cold-rolled sheet steel, the surface of the cold-rolled work roll is required to be textured to meet the requirements of customers....
