Aluminum alloy surface drawing process
Aluminum alloy surface can be drawn according to the needs of the decoration, straight lines, curly grain, threads, ripples and swirl lines and so on.
Straight-line drawing refers to machining straight lines on the surface of aluminum alloys by mechanical rubbing. It has the dual role of brushing aluminum alloy surface scratches and decorative aluminum plate surface. There are two kinds of straight-line drawing, continuous wire drawing and intermittent wire drawing. The continuous thread can be obtained by using a scouring pad or a stainless steel brush by continuously horizontally rubbing the surface of the aluminum plate (for example, hand rubbing under the condition of an existing device or brushing the aluminum plate with a planer). Changing the wire diameter of the stainless steel brush can obtain different thickness lines. Intermittent thread is usually processed on a brush or a rubbing machine. The principle of making straight-line drawing: adopts two sets of differential rotating wheels that rotate in the same direction. The upper set is a roller that rotates rapidly. The lower set is a roller that rotates slowly. The aluminum or aluminum alloy plate passes through two sets of rollers and is brushed out. Delicate interrupted rulers.
curly grain is a kind of irregular matt silk pattern with no visible lines obtained by moving the aluminum plate forward and backward and left and right under the high-speed copper wire brush. This kind of processing requires high surface quality for aluminum or aluminum alloy plates.
Ripples are usually made on a brush or a scribing machine. Using the axial movement of the upper set of grinding rollers, the aluminum alloy surface was brushed to obtain a wave pattern.
Spinning, also known as rotation, is the use of cylindrical felt or grinding stone nylon wheel mounted on the drill, with kerosene and polishing paste polishing, aluminum or aluminum alloy plate surface rotation grinding and grinding obtained by a silk pattern. It is mostly used for decorative processing of round signs and small decorative dials.
The thread is a small motor equipped with a circular felt on the shaft, which is fixed on the table, and is at an angle of about 60 degrees with the edge of the table, and is made of a drag plate with a fixed aluminum plate for pressing. A polyester film with straight edges is used to limit the thread. By using the rotation of the felt and the linear movement of the carriage, a thread pattern with the same width is spun on the surface of the aluminum plate.
