Problems solved by technology

However, the traditional brushed aluminum processing technology is cumbersome to operate, labor-intensive, and the processing cycle is long, which affects the improvement of work efficiency, and is limited in the realization of large-scale production. There are few varieties, the overall uniformity is poor, the definition of drawing lines is not high, and the metal texture is insufficient

Embodiment 1

[0020] A process for producing decorative wire-drawn aluminum strips by double-roll rolling, the specific steps are as follows:

[0021] Aluminum strip inspection: Since the brushed aluminum sheet for decoration is mainly used in high-grade decorative materials, the requirements for the raw material aluminum strip are relatively high.

[0022] Rolling and drawing: According to the pattern requirements on the drawing surface, program 24 engraving knives, and use the program to automatically control 24 engraving knives to engrave uniform and stable patterns with a depth of about 12 μm on the surface of the roll, and engrave the pattern on the roll Including straight wire drawing, cross wire drawing, mesh wire drawing, short wire drawing, long wire drawing, rough wire drawing, fine wire drawing. Clean the drawing roll before rolling, check whether the engraved pattern of the drawing roll is uniform and intact, and ensure that the rolling and drawing surface is clean and free of d...

Abstract

The invention discloses a process for rolling production of a decorative drawing aluminum strip by double rollers, belongs to the field of metal surface processing, and comprises the steps of: rolling and drawing: carving a decorative pattern on the surface of the roller by a cutter automatically controlled by a program, and rolling by placing the aluminum strip between the rollers; degreasing: performing chemical clean for the surface of the rolled and drawn aluminum strip to remove greasy dirt and pollutants on the surface; anodizing: through electrolytic oxidation, converting the surface of the aluminum strip into an oxide film; and hole sealing: sealing the hole by deionized water or distilled water. The invention has the beneficial effects that various types of decorative aluminum products on the drawing surface can be produced according to demand, the decorative pattern on the surface of the drawing aluminum plate is better in uniformity, the roller decorative pattern rolled is three-dimensional and layered so that the roller decorative pattern is stronger in metallic texture, the greasy dirt and pollutants on the surface in the degreasing step are removed, so that the surface of the aluminum strip is fully contacted with the treatment solution, so as to obtain uniform treatment effect, and the hole sealing process is performed to stabilize the anodized film.

Description

technical field [0001] The invention relates to a production process of a wire-drawn aluminum strip, in particular to a process for producing a wire-drawn aluminum strip for decoration by double-roll rolling, and belongs to the field of metal surface processing. Background technique [0002] With the improvement of people's living standards and the increasing development of the domestic construction industry and home appliance industry, new decorative materials are emerging. The demand for aluminum sheets and strips for high-quality indoor and outdoor decoration, household appliances, gift decoration, etc. is increasing. [0003] The traditional wire drawing aluminum plate production process is to use (physical treatment) mechanical friction or extrusion to process different patterns of lines on the surface of the aluminum plate. The texture can be made into straight wire drawing, random wire drawing, thread drawing, corrugated wire drawing, etc. according to different deco...
