Wire drawing die processing technology
Straight line wire drawing die refers to the aluminum plate surface with the method of mechanical friction work out straight lines. It has a brush in addition to the pin plate surface scratches and dual role of decorative aluminum plate surface. Straight line wire drawing with continuous silking and intermittent silking two kinds. Continuous silking available Bai Jiebu or small stainless steel brush through continuous straight and level counter plate surface friction (e.g., under the condition of device have by now manual skills or use the planer grinding clamp wire brush brush on the aluminum sheet mill). Change the wire diameter small stainless steel brush, with the thickness of the small grain can be obtained. Intermittent silking in brush light or the brush grain processing. Preparing principle: the two groups of synthetic differential wheel rotation, the group to rapidly spinning roller, the slow rotation of the group under the conditions of the rubber roller, aluminum or aluminum alloy passed between two groups of the roller, brush out of intermittent nine lines, fills song is under the high speed wire brush, making guide plate and friction of no rules, no obvious grain of inferior smooth silking. This kind of processing, higher requirements on the surface of the aluminum or aluminum alloy plate
Ripple in brush light or the brush grain producing, the use of on sets of roller axial movement, in aluminum or aluminum alloy plate surface grinding brush, wave type lines are obtained.
Wen also called optical, is to use a cylindrical felt or nylon wheel to grind stone on the drilling machine, kerosene and polishing ointment, hencoop pin or pin alloy plate surface rotate the kind of silking obtained grinding. It is multi-purpose ten round sign and small decorative dial wrinkle ACTS the role of sex processing.
Thread is used in the shaft with a circular felt small motor, should be fixed on the surface of the table, edge of about 60 degree Angle with the table, in addition to be a drag plate with fixed aluminum plate pressure tea, dragging plate with one edge neat straight threads polyester film used to restrict the competition degree. Using felt moves in a straight day rotation and dragging plate, the pin board rub the width of screw thread surface texture.
Sandblasting processing is to obtain light decoration or subtle reflection surfaces, to comply with a soft luster need special design. Even a moderate amount of sandblasting, basically can also overcome the common defects on the surface of the aluminum.
The appearance parts, on both drawing and sandblasting, surface oxidation treatment is usually need to do. As to choose what kind of processing technology, should be related to the modelling to consider a problem, two kinds of technology available surface texture or distinct, in addition, there are an approach to technology and sandblasting, but use a kind of chemical etching method, commonly known as chemical lousy sand processing or chemical sand surface corrosion, especially applicable to the aluminum surface treatment, its uniformity on the surface of the sand is far better than sandblasting processing. Chemical sand surface corrosion of acid corrosion and alkali corrosion. Through the different solvent corrosion and sand surface can have different surface color and degree of sand thickness.
