Embodiment 1

[0029] Embodiment 1: The laser roughening treatment method of this roll surface provided by the present embodiment still adopts such as figure 1 The existing laser texturing equipment shown is completed. The laser texturing equipment is composed of a laser and a numerically controlled machine tool 12. On the bed of the numerically controlled machine tool 12, a headstock and a tailstock are respectively installed oppositely. The rotating shaft 13 for the roll 11 to rotate, and the top 14 for pressing the roll 11 is arranged on the tailstock. Simultaneously, a translation guide rail 15 parallel to the rotation axis 13 is provided on the bed, a supporting plate is fixed on the translation guide rail 15, and a laser texturing head 10 is placed on the supporting plate; the laser texturing head 10 is provided with a first And the second two focusing heads 10-1, 10-2.

[0030] The specific texturing process is as follows: the roll 11 is placed on the rotating shaft 13 of the CNC mac...

Abstract

The invention discloses a laser texturing processing method on the surface of a roller, comprising the following steps: leading the roller to rotate with uniform velocity along self axes; simultaneously, leading a laser texturing head to move with uniform velocity along the axial direction of the roller; and periodically transmitting laser beam to the surface of the roller and forming texturing spots on the surface of the roller. The method is characterized in that by accelerating the moving speed V of the laser texturing head along the axial direction of the roller, the texturing spots are distributed along the high inclination-angle helical line with the thread pitch of delta being equal to 2-200mm on the roller. As the roller has no smooth straight line between the two rows of the texturing spots on the circumference of the surface of the roller, when rolling a steel plate, the roller and the steel plate can prevent from jointing at those parts, the iron slag grains can be absorbedby texturing concave holes crisscross distributed on the peripheral direction of the roller, scratch can not be produced on the length direction of the steel plate, and the iron slag grains can not fray and break the texturing spots, thereby greatly improving the rolling quality of the steel plate and the wearing resistance of the roller, and prolonging the service life of the roller.

Description

technical field [0001] The invention relates to a laser roughening treatment method for the surface of a roll. Background technique [0002] Cold-rolled steel sheets with special surface topography are widely used in manufacturing, especially in the automotive and home appliance industries. Textured cold-rolled thin steel sheets are rolled by rolls with textured surfaces, and the textured surface features have a great influence on the technological properties of deep drawing and coating of steel sheets. [0003] In order to improve the shape, deep drawability, elongation and coating performance of cold-rolled steel sheets, in the cold-rolled sheet production process, it is required to roughen the roll surface of the cold-rolled work rolls, and then roll them to meet the user's special requirements. The cold-rolled textured steel plate required by the process. [0004] Laser texturing is the use of high-energy pulsed laser beams to focus on the roll surface, using the high ...
