Metal wire drawing solution is to be done in the stamping mold, alloy aluminum plate metal wire drawing can be based on decorative design needs, made of straight lines, lines, external threads, waves and swirls and other categories.
Straight wire drawing refers to the parallel lines produced by mechanical friction on the surface of alloy aluminum plate. It has the bidirectional effect of removing scratches on the surface of aluminum plate and decorating the surface of alloy aluminum plate. Straight metal wire drawing has continuous silk and intermittent silk two kinds. Continuous silk lines can be used to wipe cloth or stainless steel brush according to the alloy aluminum surface to carry out continuous horizontal parallel line friction (when there is a standard manual grinding equipment or with a drill press pinch steel brush on the aluminum brush). Change the stainless steel wire diameter of the stainless steel brush, you can get different sizes of grain. Intermittent silks are generally produced and processed in brush milling machine or erasing machine. The basic principle of the system: the selection of 2 groups of rotation in the same direction of the difference of the driving wheel, the upper group of rapid rotation of the roller, the lower group of slow rotation of the glue stick, aluminum or aluminum alloy plate from the 2 groups of roller after the wheel, is brushed to the meticulous intermittently straight lines.
Striated metal wire drawing is a kind of irregular matte silk lines without significant lines obtained by moving the alloy aluminum plate around and rubbing it under the copper wire brush running at high speed. This kind of production processing, the surface of aluminum or aluminum alloy plate is higher.
Wave lines are generally made in brush milling machines or erasing machines. The radial fitness movement of the upper grinding roller is used to grind the brush on the surface of the aluminum or aluminum alloy plate, and the skipping pattern is obtained.
Spinning grain, also known as optical rotation, is a kind of silk grain obtained by rotating grinding and polishing the surface of aluminum or aluminum alloy plate by selecting cylindrical felt or stone nylon polishing wheel mounted on the planer and polishing the fat paste with gasoline blending. It is mainly used for the decorative art production and processing of ring identification cards and small and medium-sized decorative art watchcases.
External thread is fixed on the table with a small motor with ring felt on the shaft, which is about 60 degrees from the edge of the table. In addition, a tea tray with fixed fixed aluminum plate is made, and a PVC film with straight edge is attached to the tray to limit the race degree of the external thread. The outer thread lines with the same width are rotated on the surface of the alloy aluminum plate by the rotation of the felt and the parallel line of the supporting plate.
Sandblasting process is in order to get a film light decorative design or small vertical surface, in order to conform to the gloss mild and other unique design scheme. Well-proportioned sand blasting process, most can also get rid of the common shortcomings of aluminum profile surface.
On the appearance of the parts, whether with metal wire drawing or sandblasting treatment, are generally done to solve the surface air oxidation. For is to choose which kind of production process, should be related to the shape design to consider a difficult problem, two kinds of processing technology can get the surface layer feeling or there are differences.
In addition, there is a kind of alloy aluminum plate processing technology and sandblasting treatment close to, but with a kind of chemical corrosion way, alias organic chemical sand rotten solution or organic chemical sand surface etching, especially suitable for aluminum surface solution, the symmetry of the sand surface is much better than sandblasting process. Organic chemical sand surface etching can be divided into acid and alkaline etching and alkali-partial etching. Different surface color and sand grain size can be obtained according to different organic solvent and sand surface agent.
