A pattern is first drawn, and then, the pattern is printed on a stainless steel plate by a screen processing mode. Protective films are attached to the periphery space of the pattern and a proper position in the pattern, and then, corrosion processing is carried out to form point-shaped, linear or partial plane patterns. Various stainless steel products are made by stamping, polishing and reprocessing. The original pattern can be extended and expanded in a longitudinal direction and a transverse direction after stamping processing, and the point-shaped, linear or partial plane patterns are outstanding and clear.

Description

Pattern forming method on stainless steel products

The present invention relates to the manufacture method of pattern on a kind of stainless steel products, this method is utilized screen printing technology, cooperates certain work flow arrangement, makes surface of stainless steel product can form supereminent pattern, so as to increasing the sense of worth of stainless steel products.

Because stainless steel material possesses the characteristic that quality is good, intensity is high, many in recent years senior tablewares, diet articles for use, gradually adopted stainless steel manufacturing, but because of the surface of stainless steel products after the polishing program, all form wet look in the surface, the dapple silverware of general surface carving is for poor, so for improving the sense of worth of stainless steel products on sense of worth, the producer who has is convenient for punch die technology, engraving technology, makes pattern at surface of stainless steel product.But utilize punch die technology, engraving technology to make pattern and have following defective:

(1) punch die technology: if desire utilizes the punch die technology to make comparatively complicated patterns, just need to utilize earlier carving mould technology depiction on mould, utilize mould to come punching press afterwards again, because carving mould expense is higher, therefore the cost of manufacture of pattern is improved relatively, and because of the pattern that utilizes the punch die technology to be gone out can be convex shape at reverse side, not only not attractive in appearance, also can influence the sense of worth of goods.

(2) engraving technology: this technology is to utilize artificial or machinery is directly carved in product surface, but the human cost that this mode not only spends is high, speed is slow, and make stainless steel products become expensive goods with pattern, and in the engraving process,, carelessness causes the engraving error if being arranged slightly, then discarded for keeping quality just to need with these semi-finished product, the cost that has just more increased stainless steel products like this; Moreover utilize engraving technology, only can produce picture on surface is plane or concavo-convex more shallow goods, and can't produce the concavo-convex darker goods of pattern.

Because technical problem, the stainless steel products that causes present this kind surface to have pattern still belongs to high-grade article in European countries, and can't be extensive use of; So for sense of tool high value and inexpensive stainless steel products can be produced in a large number, the present invention proposes the manufacture method of pattern on a kind of stainless steel products, this manufacture method cooperates with work flow by screen printing technology, can produce stainless steel products in a large number, make stainless steel products be possessed inexpensive characteristic and be extensive use of with pattern.

Main purpose of the present invention is: the manufacture method that pattern on a kind of stainless steel products is provided; this manufacture method is after drawing good pattern earlier; make half tone then; then pattern is printed on the stainless steel flat plate by screen painting; brush diaphragm more thereon; make the peripheral space and the interior point-like of pattern of pattern; diaphragm is adhered at the decorative pattern place of wire or part plan; afterwards flat board is inserted in the etching tank; corrosion through chemical agent; can in the zone of pattern, form point-like; the pattern of wire or part plan; pass through stamping technology afterwards again; polishing technology; the reprocessing technology; can make various stainless steel products; and goods can make original pattern be expanded through after the punching press program, make pattern more obvious; outstanding.

Another object of the present invention is to: the manufacture method that pattern on a kind of stainless steel products is provided, this method is by polishing technology, make the space of pattern periphery form the light face, the pattern with point-like, wire or part plan enhances each other's beauty whereby, and increases the sense of worth of stainless steel products.

The present invention proposes the manufacture method of pattern on a kind of like this stainless steel products; draw earlier on rough sketch; then; utilize the half tone processing mode to be replicated on the steel plate in pattern; make again on the outer zone of pattern on the steel plate and point-like, strip or the part plan in the pattern and form diaphragm; afterwards steel plate is inserted and carry out extent of corrosion in the etching tank; make the pattern of partial corrosion formation point-like, wire or the part plan of unprotect film on the steel plate; utilize punching press, polishing and reprocessing technology afterwards again, make a stainless steel products.

Below in conjunction with accompanying drawing purpose of the present invention and characteristics are described further.

Wherein:

Fig. 1 is a schematic flow sheet of the present invention;

Fig. 2 is attached to the schematic diagram on the steel plate for the present invention draws.

Please referring to shown in Figure 1, manufacture method of the present invention includes (1) and paints original text plate-making (2) printing (3) corrosion program (4) punching press (5) polishing (6) reprocessing program, and details are as follows:

(1) paint original text plate-making:

The pattern protract that the consumer is liked is on original text at first earlier, as flowers, trees, the animal of building or having dense Chinese taste, scenery with hills and waters pattern, then rough sketch is taken a picture and make egative film, and handle simultaneously, make the decorative pattern that forms point-like, strip or part plan on the pattern; To print online glue, half oven dry, utilize the photo egative film of making to carry out sensitization photograph program afterwards again, it is online to make pattern adhere to seal, this moment, the pattern place was adhered to because of sensitization makes colloid, then can the colloid on the point-like in pattern exterior domain and the pattern, strip or the part plan decorative pattern can be removed, and the pattern place still be attached with colloid by cleaning procedure.

(2) printing:

Half tone is placed on the stainless steel flat plate, utilize brush to be coated with upper protective film, the zone at pattern place is promptly by the stopping of colloid, and makes the diaphragm can't infiltrate, and decorative pattern is then owing to making the diaphragm infiltrate then be attached with diaphragm in the outer zone of pattern and the pattern; Diaphragm is attached on the steel plate, and by the coverage of half tone, make to form pattern on the steel plate, and the periphery of pattern has diaphragm (as shown in Figure 2).

(3) corrosion program:

Steel plate is inserted in the etching tank that fills chemical agent; corrosion by chemical agent; make pattern place that not protected film covers be subjected to the corrosion of chemical agent; form the pattern of point-like, wire or part plan; for the intensity that makes steel plate not the reason corrosion process be affected; time of corrosion process must cooperate the thickness of steel plate and do suitable adjustment, so that the certain thickness of tool still of the steel plate after the corrosion.

(4) punching press:

Utilize hydraulic press or double action punch press that steel plate is carried out towards the volume degree, make steel plate make the embryo of goods, after the pattern process punching press program on the steel plate,, make pattern show more, give prominence at this moment even the longitudinal and transverse direction of pattern is extended, expanded.

(5) polishing:

Utilize the polishing program, make half-finished surface form wet look, so because of the pattern place is slightly recess, thus make the outer zone of pattern be bright, and make bright to enhance each other's beauty with pattern through excessive erosion, make the kenel of pattern obvious more, give prominence to.
