Description
Technical Field
The invention relates to a method for producing decorative plates for metal doors and metal windows, in particular to a production process of a coiled stainless steel decorative plate.
Background
Chinese patent publication No. CN103710690A discloses a surface coloring process for stainless steel coils or flat plates, comprising the following steps:
1) Installing a whole roll of stainless steel coiled plate on an unreeling machine of a production line and fixing or placing a stainless steel flat plate on a discharging platform;
2) Conveying the fixed stainless steel coil plate or the fixed stainless steel flat plate to a surface treatment machine for surface treatment;
3) Conveying the stainless steel coiled plate or the stainless steel flat plate with the treated surface to a cleaning machine, and cleaning impurities on the surface;
4) Conveying the cleaned stainless steel coiled plate or stainless steel flat plate to an oven for electric heating baking to dry the water on the surface;
5) After the surface is baked, cooling the stainless steel coiled plate or the stainless steel flat plate by using a fan;
6) Conveying the cooled stainless steel rolling plate or stainless steel flat plate to a packaging position for surface packaging film pasting;
7) The stainless steel coiled plate after being pasted with the packaging film enters a winding machine to be wound into a bundle or a stainless steel flat plate to be subjected to wooden box packing;
8) Moving the collected stainless steel coiled plate to an unreeling machine of coloring equipment and fixing or moving the boxed stainless steel flat plate to a discharging platform of the coloring equipment;
9) Unreeling the fixed stainless steel coiled plate or unpacking the stainless steel flat plate, simultaneously tearing off the packaging film on the surface manually or by using a film reeling machine and conveying the packaging film into a cleaning machine, and cleaning the surface of the stainless steel coiled plate or the stainless steel flat plate;
10 Conveying the cleaned stainless steel rolled plate or stainless steel flat plate to an oven for baking by an electric heating lamp to dry the surface moisture;
11 Conveying the baked stainless steel coiled plate or the stainless steel flat plate to a cooling position, and cooling by using a fan;
12 Conveying the cooled stainless steel coiled plate or stainless steel flat plate to a coloring part of coloring equipment, and carrying out roller coating coloring on the stainless steel coiled plate or the stainless steel flat plate by a rubber roller coated with color oil on the coloring equipment;
13 Roller painting and coloring the surface of the stainless steel rolling plate or the stainless steel flat plate, then conveying the stainless steel rolling plate or the stainless steel flat plate to an oven, baking by using an electric heating lamp, and drying and curing the colored oil;
14 The stainless steel coiled plate or the stainless steel flat plate is conveyed to an air cooling place after coming out of the oven, and the air cooling is carried out by a fan;
15 Conveying the cooled stainless steel rolled plate or stainless steel flat plate to a packaging position for surface film packaging;
16 Finally, the stainless steel rolled plate pasted with the packaging film is wound into a bundle by a winding machine or the stainless steel flat plate pasted with the packaging film is subjected to wooden box packing.
The surface treatment in the step 2 is to grind the surface by a nylon roller to form a frosted surface, grind the surface by an annular abrasive belt at a high speed to form snowflakes, use the annular abrasive belt to tension by a cylinder to draw out drawn wires or use wool felt and nitric acid to grind the circular abrasive belt into a mirror surface, and carry out the surface treatment on a rolled plate or a flat plate, thereby enhancing the appearance effect of the product and leading the product to be more beautiful. The thickness of the stainless steel coiled plate or the stainless steel flat plate is 0.15-2.0 mm; the oven is of a tunnel type, the length of the oven is 20-30 meters, the width of the oven is 0.6-1.8 meters, the height of the oven is 0.9-1.2 meters, and the oven adopts a lamp tube for electric heating; the baking temperature of the electric heating lamp is 180-320 ℃, preferably 230 ℃; the total length of the production line is 60-90 m.
Because the stainless steel coil plate or the stainless steel flat plate has harder hardness, if the thicker stainless steel coil plate or the thicker stainless steel flat plate is adopted for producing and coloring to form a coloring layer, the stainless steel material is expensive, and the production cost is high;
if a thicker stainless steel rolling plate or a stainless steel flat plate is adopted, the coloring color layer can be kept not to be damaged when the stainless steel rolling plate or the stainless steel flat plate is used as a plane plate such as a door, a window and the like, the whole stainless steel rolling plate or the stainless steel flat plate is not soft, and the stainless steel rolling plate is suitable for a door plate and a window plate with a wider area; when the stainless steel is used as door and window profiles, such as door frames, window frames and the like, a large profile bending machine and a die are required for bending and shaping, the pressure for bending and shaping is high, the ductility of stainless steel is poor, a coloring layer on the surface is easy to crack, explode (delaminate), crack, scratch, wear and the like at a bent part, and the whole appearance is attractive and is not complete;
if a thinner stainless steel rolling plate or a stainless steel flat plate is adopted for production coloring, the price is much cheaper; if the colored panel is used as a plane panel such as a door, a window and the like, the colored color layer can be kept undamaged, but the whole panel is soft, is not suitable for a door panel and a window panel with a wider area, is only suitable for a plane with a small width and a small length, and is troublesome because a metal bracket is required to be added on the back of the plane panel for use with a wider area; if the material is used as door and window profiles, such as door frames, window frames and the like, the formed frame shell is not hard enough, and the installed door and window are not firm enough.
