The wire drawing treatment should be done after stamping. Generally, the wire drawing should be done first and then oxidized to ensure the corrosion resistance after wire drawing. Most of the 3003 anti rust aluminum plates are used for wire drawing. According to the decoration needs, straight lines, random lines, threads, ripples and spiral lines can be made. Let's talk about the drawing process of aluminum plate manufacturers.
Straight wire drawing: refers to the process of machining straight lines on the surface of aluminum plate by mechanical friction. The utility model has the double functions of brushing the scratches on the aluminum plate surface and decorating the aluminum plate surface. Straight wire drawing can be divided into two types: continuous wire drawing and intermittent wire drawing. The continuous silk pattern can be continuously rubbed horizontally and straightly on the aluminum plate surface with a cleaning cloth or a stainless steel brush. Intermittent silk patterns are generally processed on the brushing machine or the erasing machine. Manufacturing principle: two groups of differential wheels rotating in the same direction are used. The upper group is a fast rotating grinding roller, and the lower group is a slow rotating rubber roller. The aluminum or aluminum alloy plate passes through the two groups of rollers and is brushed with fine intermittent straight lines.
Random wire drawing: It is a kind of irregular and non obvious matt silk pattern obtained by moving and rubbing the aluminum plate from front to back, left to right, under the high-speed copper wire brush. This kind of processing has high requirements on the surface of aluminum or aluminum alloy plates.
Corrugated wire drawing: Corrugated wire is generally made on the brushing machine or the erasing machine. Use the axial movement of the upper group of grinding rollers to grind and brush on the surface of aluminum or aluminum alloy plates to obtain wavy patterns.
Spinning wire drawing: Spinning wire, also known as optical rotation, is a kind of wire pattern obtained by using cylindrical felt or grinded nylon wheel to install on the drilling machine, mixing kerosene with polishing paste, and rotating polishing the surface of aluminum or aluminum alloy plate. It is mainly used for decorative processing of round signs and small decorative dials.
Thread drawing: a small motor with a round felt on the shaft is used to fix the thread on the table, forming an angle of about 60 degrees with the edge of the table. In addition, a carriage with fixed aluminum plates for pressing tea is made, and a polyester film with straight edges is pasted on the carriage to limit the thread race. Using the rotation of felt and the linear movement of the carriage, a thread pattern with the same width is spun on the aluminum plate surface.
Sand blasting is to obtain the surface of film light decoration or fine reflective surface to meet the special design requirements such as soft luster. Uniform and moderate sand blasting can basically overcome the common defects on the aluminum surface.
For appearance parts, whether drawing or sandblasting is used, surface oxidation treatment is usually required. As for the choice of processing technology, it should be a question related to modeling. The surface texture obtained by the two processes is different.
