Abstract
The invention provides a method for energy-saving, environment-friendly and large-scale production of a spot copper product. The method comprises the steps of shaping and heating a copper plate, preserving the heat for 10 minutes to 5 hours at 300-1000 DEG C under a protective atmosphere to ensure that a metal crystal in a product grows up; performing intercrystalline corrosion for 10 minutes to 1 hour by using a ferrous sulfate or iron trichloride solution of which the mass concentration is 20-50%; washing with water; drying; spraying a finish paint to obtain the spot copper product. By adopting the method, the process steps are greatly simplified, the cumbersome processes of manual forging, precision casting and the like are abandoned, the labor intensity is reduced, the raw material loss is reduced, the working efficiency is improved, and because a strong acid is not used for showing spots, energy conservation and emission reduction are effectively realized, pollutions can not be caused to the environment, and the method is favorable for large-scale production. By adopting the method disclosed by the invention, the products including spot copper as well as glazed tin, glazed silver and glazed gold spot copper, spot brass as well as glazed tin, glazed silver and glazed gold spot brass and the like can be produced to meet market requirements.
Description
Technical field
The working method that the present invention relates to a kind of spot copper, spot brass ware, belongs to hardware processing technique field.
Background technology
The raw material of spot brass work all be unable to do without tough-pitch copper for a long time, namely exploitation copper billet out.Along with the minimizing increasingly of tough-pitch copper quantity, cost of material is more and more higher, causes the price of spot brass work more and more expensive.Adopt hand-forged spot brass work out, need to be through heating many times, anneal, forge moulding, not only quite power consumption, and often move back once fire and also will produce once oxidation copper junk, after forging, also to frustrate hammer flattener and print, lost again copper powder, that is to say also suitable consumptive material, complete processing is numerous and diverse simultaneously, long processing time, production efficiency is low, and labour intensity is large.In addition, when brass work is carried out to " burned spot ", need to consume wooden carbon, cause forest reserves consumption, be difficult to control the precise temp of ± 2 ℃ simultaneously, inevitably can produce Red copper oxide; When " aobvious spot ", use multiple strong acid brass work is carried out, the harm that human body and environment are caused is serious, treatment time reaches 3 hours more than, and the spent acid producing becomes again a difficult problem, in cleaning the process of residual acid, need to use pure water, waste is large, and cost is high.
Summary of the invention
The object of the present invention is to provide a kind of method of energy-saving and environmental protection and energy large-scale production spot brass work.
The present invention completes by following technical proposal: a kind of method of energy-saving and environmental protection, large-scale production spot copper, spot brass ware, is characterized in that comprising the following steps:
1) by copper coin after conventional moulding, send in process furnace, under 300-1000 ℃, protective atmosphere, be incubated 10 minutes～5 hours, the Metallic Solids in goods is grown up;
2) goods that step 1) heated cool to the furnace after room temperature, put into ferrous sulfate or liquor ferri trichloridi that mass concentration is 20-50%, carry out intergranular corrosion 10 minutes～1 hour;
3) by step 2) goods that corroded are the tap water washing 30-60 minute of 50～60 ℃ by temperature;
4) goods after step 3) washing are sent in loft drier, at 80～100 ℃ of temperature, dried, come out of the stove and be cooled to after room temperature, through routine spraying finishing paint, obtain spot brass work.
The copper coin of described step 1) is that thickness is copper sheet or the sheet brass of 0.5～5mm.
The conventional moulding of described step 1) is: adopt the copper coin that conventional punch press is 0.5～5mm by thickness to strike out required goods moulding.
The conventional moulding of described step 1) is: adopt conventional digital-controlled carving machine or hand engraving, the copper coin that is 0.5～5mm by thickness is engraved as required goods moulding.
The conventional moulding of described step 1) is: adopt conventional digital-controlled carving machine or hand engraving, the copper coin that is 0.5～5mm by thickness is engraved as required goods moulding, more a kind of soldering in coloured glaze tin or coloured glaze silver or coloured glaze gold or gold-plated or silver-plated, through routine, polishes.
The conventional moulding of described step 1) is: by metallic copper material spraying or electroforming, to model, spraying or electroforming thickness are 0.5～1mm.
The protective atmosphere of described step 1) is carbon monoxide, nitrogen or the argon gas of sending into convention amount in process furnace, makes the spot copper can be not oxidized in stove.
The Heating temperature of described step 1) and soaking time are looked goods size, thickness and required grain size and are specifically determined.
Described step 2) the intergranular corrosion time highlights size depending on goods size, thickness and required crystal grain and specifically determines.
The present invention has following advantages and effect: adopt such scheme, without using again tough-pitch copper as raw material, only needing to adopt industrial copper coin is raw material, through conventional punching press, engraving, spraying, after the moulding such as electroforming, send process furnace heating, insulation, make grain growth, through ferrous sulfate or liquor ferri trichloridi, carry out intergranular corrosion again, washing, dry, surface spraying finishing paint, obtain spot brass work, not only greatly simplify processing step, abandon manual making and the loaded down with trivial details operation such as precision casting, reduce labour intensity, reduce significant loss, increase work efficiency, and because not using strong acid to show spot, effectively energy-conservation, reduce discharging, can be to environment, do not damage operator healthy, be conducive to environmental protection, more be conducive to large-scale production, make goods maintain par, at a low price, expand sphere of consumption, by the present invention, can produce spot copper and coloured glaze tin, coloured glaze silver, coloured glaze gold spot copper, spot brass and coloured glaze tin, coloured glaze silver, the goods such as coloured glaze gold spot brass, meet the need of market.
Patch size on the spotted copper member that the present invention produces is consistent, has passed on ancient technology home built spot brass work feature, and can pass through controlling of production process Patch size.In production process, environmental protection completely can be up to standard, and copper sulfate or cupric chloride in the waste liquid after intergranular corrosion simultaneously also can extract, and do not waste copper resource, and washing water, after zwitterion plastic resin treatment, activated carbon treatment, then pass through reverse osmosis membrane processing, can be recycled.
