Abstract
This invention unfurls a kind of watchcase with high intensity made of gold of 98 percent content and its producing technics. It comprises the following steps: a. produce the moulds; b. pour the melted gold into the plaster mould to form the watchcase flan organ.; c. launder them to get rid of the impurity; d. put the flan organ in the oil pressed steel mould, and extrude watchcases with the oil presser or liquid presser; e. lay them in the steel punch mould to punch the flying border away; f. process the watchcase flan organs into finished products according to the present technics. This producing technics has simple technology and short producing periods. Besides the gold rigidity of the produced watchcase is greatly improved and uneasy to be metamorphosed, whose wastage of the processing materials is below 3 percent.
Description
Technical field
The present invention relates to watchcase and manufacturing process thereof that a kind of gold is made, particularly relate to a kind of watchcase and manufacturing process thereof with the content gold manufacturing that (comprises 98%) more than 98%.
Background technology
Along with the raising of people's living standard and level of art appreciation, table no longer has been a kind of instrument that shows the time.Shape, the material of table and the mode of wearing of table have also broken away from traditional idea, and the class of table more manifests owner's identity, and especially the gold wrist-watch more can embody owner's noble quality and Hua Fu, and its style, shape more can embody owner's individual character.
Content is softer because of quality at the gold material more than 98%, tooth has been stung seal, bending easily, golden yellow color, pure, soft, feel is heavy, is easy to melting welding processing and is used for the jewellery industry in a large number by people in history, but blemish in an otherwise perfect thing is because of its hardness deficiency, easily deformable, picked wound by sharp thing easily, destroy its surface and glossiness.In order to increase its hardness, people add small amount of silver, copper to gold and become karat gold (as 22K, 20K, 18K etc.) in history, but gold content is reduced, can not make it become proof gold, it is pure to destroy it first, second be difficult for identifying its content, three are difficult for normally circulating on market or being processed into ornaments again.
The main material that gold is decorated as jewellery, its great advantage is to be easy to welding processing.Its processing technology is with a long history, and the emphasis of its process technology is a solder technology.Therefore, the processing of gold jewelry decoration be unable to do without this technology of welding.But softer by its quality of gold ornament that solder technology processes, bending distortion easily influences its permanance attractive in appearance and durable largely.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of high-intensity watchcase and manufacturing process made from content 98% above gold thereof is provided.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
One, makes mould:, make gypsum mould mould, engraving punching press punching block and oil press or hydropress punching block by the style requirement according to market demand development and Design style.
Two, pouring: form the watchcase blank pouring into the gypsum mould mould after the gold fusing.
Three, clean removal of impurities: the watchcase blank is put into chemical solution clean up, remove impurity, scrape blank repeatedly, make blank surface-brightening, no obvious impurity and crack with agate.
Four, oil pressure: blank is put into the oil pressure punching block extrude watchcase with being no less than 200 tons of oil presses (or hydropress) with upward pressure.
Five, punching press: the watchcase blank that oil pressure is come out is put into the steel drift mould and is washed away overlap (burr) because of the oil pressure watchcase forms.
Six, be processed into finished product: the watchcase blank is processed into finished product according to prior art.
Above-mentioned process for machining and manufacturing can be used for producing jewellery such as pendant watchcase, ring watchcase equally.
The invention has the advantages that:
One, adopt its gold hardness of watchcase of this fabrication process to improve greatly, not yielding, corresponding surface gloss might as well.
Two, technology is simple, and is with short production cycle, is easy to produce characteristic watchcase according to turn of the market and demand.
Three, the equipment of Shi Yonging is few and simple, small investment, and output is changeable.
Four, owing to adopt the above gold material processing watchcase of 98% content, its rapidoprint loss is below 3%, if with karat gold as its processing loss of material more than 120%.
Embodiment
Further specify the present invention below by embodiment.
Embodiment 1
One, makes mould:, make gypsum mould mould b. processing engraving punching press punching block and oil pressure (or hydropress) punching block by style requirement: a. according to market demand development and Design style.Its molten point of the employed material of gypsum mould mould must be more than 1100 ℃, and just the molten point of its material must be than gold height, and gypsum mold was indeformable when the gold after guaranteeing to dissolve poured into.Watchcase blank in the gypsum mould mould is a crude green body, its crude green body thickness, width must be all thicker, wide than the watchcase in the punching block, its cumulative volume or weight are bigger or heavy by about 10% than the watchcase in the punching block, to guarantee that its crude green body has abundant gold to make watchcase full, solid, bright, does not form cavity or core in punching block.Punching block technical requirement: 1, absolute light; 2, specification is accurate; 3, indeformable under 250 tons of pressure, do not break.Punching block profile or thickness can be made according to watchcase style and size, and the gypsum mould mould can be made watchcase of a mould or a mould 50-200 watchcase according to watchcase output.
Two, pouring: form the watchcase blank pouring into the gypsum mould mould after the gold fusing.If have a plurality ofly during to more than hundred watchcases in mould of gypsum mould mould, pouring gold must be with vacuum machine or centrifugal casting machine, to guarantee its blank success ratio.
Three, cleaning removal of impurities: the watchcase blank is put into chemical solution clean up, remove impurity, scrape its blank repeatedly, make the blank surface-brightening not have obvious impurity and crack with agate.Chemical solution can be various common chemical solution such as nitric acid, sulfuric acid, hydrochloric acid, contrary chloroazotic acid, positive chloroazotic acid, potassium cyanide.
Four, oil pressure: blank is put into the oil pressure punching block extrude watchcase with being no less than 200 tons of oil presses (or hydropress) with upward pressure.This moment, watchcase hardness was brought up to original more than two times by mohs hardness 2.5%.
Five, punching press: the watchcase blank that oil pressure is come out is put into the steel drift mould and is washed away overlap (burr) because of the oil pressure watchcase forms.
Six, be processed into product: use the diamond cutter of different angles that watchcase surface and glass position are processed with lathe; Use the different size cutter that watchcase hollow bulb part is processed with engraving machine, as anti-water level, groove position (button bottom groove position), literary name face position etc.; Barre position and watchband position with drilling machine processing watchcase; With instruments such as buffing machine diamond cutter, drill bit, agate cutter, scalpels above-mentioned watchcase is polished, repairs and make it become finished product.
