Abstract
The invention discloses a fabrication method of copper crafts. The copper crafts are refined by eight procedures of smelting and melting copper; casting a sand table; welding accessories; polishing, trimming, finishing and plating; marking off and engraving; engraving designs, and spraying baking finish and molding. The mass fraction percent of copper and other metals is reasonably set, so that the processed copper crafts do not change in color, and are not easily oxidized at the same time. By adopting the procedures, the problems of size deformation, air shots, air bubbles and the like of the crafts are completely eradicated effectively, the repair amount and the defective index of the crafts are reduced, meanwhile, the quality of the crafts is improved, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of preparation method of handicraft, be specifically related to a kind of preparation method of copper handicraft.
Background technology
The copper handicraft of Pakistan is due to its lifelike image, high-end atmosphere, multiplex in high-grade hotel, the fitting-up of company conference hall and senior house, magnificent style, also can be used for that household is interspersed and handicrafts commemorative simultaneously, the manufacture craft of the copper handicraft of existing Pakistan has multiple, can make hundreds of varieties, due to the fusing point height of copper and the impact of casting character, be difficult to the casting accuracy that reaches higher, must pass through meticulously chiseling and carving of later stage, in addition the price of copper own is high, so handicraft price and the production cycle of copper are long, mainly there is following problem in existing copper product manufacture craft:
1, owing to grasping the mass fraction percentage of bad copper and other metals, to cause the copper handicraft processing easily to become the color while easily oxidized.
2, because manufacture craft is improper, copper handicraft often there will be the problems such as size distortion, sand holes, bubble, the large even high problem of percent defective of the amount of reprocessing.
The problems referred to above have had a strong impact on product quality and production cost, cause unnecessary waste and economic loss to copper handicraft processing enterprise.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of preparation method of copper handicraft, this preparation method has reasonably been formulated the preparation method of copper product technique, effectively reduces production cost, reduces economic loss.
Object of the present invention is carried out specific implementation by the following technical programs:
A preparation method for copper handicraft, comprises the following steps:
(1) smelt molten copper: by mass percentage, by 72% ~ 78% copper, 8% ~ 12% tin, 10% ~ 14% aluminium plumbous and 1% ~ 5% is placed on to smelt in spoon and melts, and makes copper water mixed liquid used in order to casting mold; Soft and hard by the grinding tool of this proportion casting, be applicable to engraving, and copper thorn easily comes off.
(2) sand table casting mold: select sand table according to the respectively accessory shape to be cast of product, the shape of accessory that discharge by pressing is cast on sand table, and be coated with and dye paraffin on surface, can there is not product bubble in grinding tool like this, good seal sand table, injects above-mentioned copper water mixed liquid in sand table and carries out casting mold;
(3) accessory welding: accessory good founding is required to weld one by one according to the integrated planning of product, and the product of moulding complexity repeatedly repeats match-place welding;
(4) polishing finishing: the finished product blank of having welded is polished, soldering opening and match-place place are polished flat completely, remove all the other irregular parts, repair trickle part and the contact-making surface with ground or desktop;
(5) polishing is electroplated: after product polishing, its entirety is carried out to preliminary polishing finishing, then carry out the fine grinding polishing of surface flatness, the electroplating processes of color is carried out on surface after handling well completely;
(6) line engraving: delineating and segmenting of profile carried out on the shaping grinding apparatus surface after polishing being electroplated by product programming requirement, marks off the initial profile of engraving and coloured part and pattern;
(7) texturing are chiseled and carved: after the initial profile of product occurs, according to finished product needs, first the colorful one carries out painted, and then baking vanish or spray paint chisels and carves texturing;
(8) spray, baking vanish moulding: after product has been chiseled and carved, first product surface is carried out to wiping, grind off the copper scale that remains in finished surface, finally carry out anti-oxidation spray, the paint baking on surface.
Further, when product is carried out to polishing, first use sander to carry out preliminary entirety polishing finishing, then with crocus cloth sander, carry out the fine grinding polishing of surface flatness.
The engraving process of further, product being carried out to texturing while chiseling and carving, can adopt that side tool is carved, vertical cutter cutter or flat cutter being cut.
Further, when smelting molten copper, by mass percentage, putting into copper is 75%, and tin is 10%, and lead is 12%, and aluminium is 3%.
The preparation method of a kind of copper handicraft of the present invention, adopt and smelt molten copper-sand table casting mold-accessory trimming polished plating-line engraving-texturing of weld-polishing and chisel and carve-spray, baking vanish moulding totally eight procedure exquisitenesses forms, reasonably set the mass fraction percentage of copper and other metals, it is oxidized that the copper handicraft that makes to process does not allow variable color to be difficult for simultaneously, adopt above-mentioned operation effectively to stop the size distortion of handicraft, sand holes, the problems such as bubble, the handicraft amount of reprocessing and percent defective are reduced, improve handicraft quality simultaneously, reduced production cost.
Accompanying drawing explanation
Fig. 1 is the flow chart of the preparation method of a kind of copper handicraft of the present invention.
The specific embodiment
embodiment 1
The preparation method of a kind of copper handicraft described in the embodiment of the present invention, as shown in Figure 1, comprises the following steps:
(1) smelt molten copper: by the copper of 1.5kg, the tin of 0.2kg, the lead of 0.24kg and the aluminium of 0.06kg are placed on to be smelted in spoon, again smelting spoon is placed on charcoal fire stove and is melted, when temperature reaches 1083 ℃ of left and right, copper ingot is molten into copper water, make copper water mixed liquid used in order to casting mold; Soft and hard in the grinding tool of this ratio casting, be applicable to engraving, and copper thorn easily comes off.
(2) sand table casting mold: according to the respectively accessory shape to be cast of product, select suitable sand table to fill with fine sand, the shape of accessory that discharge by pressing is cast on sand table, and be coated with and dye paraffin on surface, can there is not product bubble in grinding tool like this, and good seal sand table injects copper water mixed liquid in sand table and carries out casting mold; After 20 minutes, open sand table, pour out fine sand, remove accessory irregular perimeter part.
