Description

A kind of making method of copper artwork
Technical field
The present invention relates to a kind of making method of artwork, be specifically related to a kind of making method of copper artwork.
Background technology
The copper artwork of Pakistan is due to its lifelike image, high-end and atmospheric, multiplex in high-grade hotel, the fitting-up of conference hall of company and senior house, magnificent style, also can be used for household to intersperse and handicrafts commemorative simultaneously, the manufacture craft of the copper artwork of existing Pakistan has multiple, hundreds of varieties can be made, due to the fusing point height of copper and the impact of castability, be difficult to reach higher casting accuracy, have to pass through meticulously chiseling and carving of later stage, in addition the price of copper own is high, so the artwork price of copper and the production cycle long, mainly there is following problem in existing brass work manufacture craft:
1, it is simultaneously easily oxidized that the massfraction per-cent owing to grasping bad copper and other metals causes the copper artwork processed easily to become color.
2, because manufacture craft is improper, copper artwork often there will be the problems such as size distortion, sand holes, bubble, the large problem that even scrap rate is high of the amount of reprocessing.
The problems referred to above have had a strong impact on quality product and production cost, cause unnecessary waste and financial loss to copper artwork processing enterprise.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of making method of copper artwork, this making method has reasonably formulated the making method of brass work technique, effectively reduces production cost, reduces financial loss.
Object of the present invention carrys out specific implementation by the following technical programs:
A making method for copper artwork, comprises the following steps:
(1) smelt molten copper: by mass percentage, by the copper of 72% ~ 78%, the tin of 8% ~ 12%, the lead of 10% ~ 14% and the aluminium of 1% ~ 5% are placed on to smelt in spoon and melt, and make copper water mixed liquid used in order to casting mold; The grinding tool cast by this proportional range is soft and hard, is applicable to engraving, and copper thorn easily comes off.
(2) sand table casting mold: respectively treat that casting accessory shape selects sand table according to product, on sand table discharge by pressing cast the shape of accessory, and being coated with dye paraffin on surface, can not there is product bubble in such grinding tool, good seal sand table, injects above-mentioned copper water mixed liquid in sand table and carries out casting mold;
(3) accessory welding: accessory good for founding is required to weld one by one according to the integrated planning of product, the product of moulding complexity repeatedly repeats match-place welding;
(4) polishing finishing: the finished product blank of weld polished, soldering opening and match-place place are polished flat completely, removes all the other irregular parts, repairs discreet portions and the contact surface with ground or desktop;
(5) polishing plating: after product polishing, its entirety is tentatively polished finishing, then carry out the fine grinding polished finish of surface flatness, surperficial handle well completely after carry out the electroplating processes of color;
(6) line engraving: by product planning requirement, delineating and segmenting of profile is carried out to the shaping grinding apparatus surface after polishing plating, mark off the initial profile carved with 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, baking vanish or spray paint, and then carry out chiseling and carving texturing;
(8) spray, baking vanish is shaping: after product has been chiseled and carved, first wiping is carried out to product surface, grind off the copper scale remaining in finished surface, finally carry out the anti-oxidation spray on surface, paint baking.
Further, when carrying out polished finish to product, first using sander to carry out preliminary overall polishing finishing, then carrying out the fine grinding polished finish of surface flatness with crocus cloth sander.
Further, when carrying out texturing to product and chiseling and carving, the engraving process that side tool is carved, vertical cutter is cut a hole or flat cutter is cut can be adopted.
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 making method of a kind of copper artwork of the present invention, molten copper-sand table the casting mold of smelting-accessory welding-polishing finishing-polishing plating-engraving-texturing of ruling are adopted to chisel and carve-spray, the shaping totally eight procedure exquisitenesses of baking vanish form, the massfraction per-cent of rational setting copper and other metals, the copper artwork processed is made not allow variable color simultaneously not easily oxidized, the size distortion of artwork that adopted above-mentioned operation effectively to stop, sand holes, the problems such as bubble, the artwork amount of reprocessing and scrap rate are reduced, improve artwork quality simultaneously, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the schema of the making method of a kind of copper artwork of the present invention.
Embodiment
Embodiment 1
The making method of a kind of copper artwork 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 melts, when temperature reaches about 1083 DEG C, copper ingot is molten into copper water, obtained copper water mixed liquid is used in order to casting mold; The grinding tool cast in this ratio is soft and hard, is applicable to engraving, and copper thorn easily comes off.
(2) sand table casting mold: respectively treat casting accessory shape according to product, selects suitable sand table to fill with fine sand, on sand table discharge by pressing cast the shape of accessory, and dye paraffin is coated with on surface, can not be there is product bubble in such grinding tool, good seal sand table, injected in sand table by copper water mixed liquid and carry out casting mold; Open sand table after 20 minutes, pour out fine sand, remove accessory irregular perimeter part.
