Abstract

The invention relates to an alloy material for manufacturing jewelries, in particular to a tungsten alloy material and a method for manufacturing the jewelries, belonging to the technical field of jewelry manufacture. The tungsten alloy material comprises the following main components in percentage by weight: 85-88.5% of Tu, 5-9.5% of Ni, 0.5-3% of Cr, 1-2% of Co and 0.5-3% of Mo. The tungsten alloy material has light and smooth surface, sufficiently performs the rigidity and the brightness of tungsten and is incorrosive, fadeless and difficult to smash; and the surface is difficult to scratch.

Description

A kind of tungsten alloy material and making jewellery method of making jewellery

Technical field:

The present invention relates to make the alloy material and making jewellery method and technology field of jewellery, refer in particular to a kind of tungsten alloy material and making jewellery method of making jewellery.

Background technology:

Bullion is worn ingenious, can make you satisfied happy, in high spirit, in people's aesthetic activity, and bullion and to wear always all be absolute the important lesson.Bullion is because of its material difference of selecting for use, and color difference, quality difference, design style difference, technology are done manual work and used and usual method different different comprising, the sensation of bringing to the people also is different naturally.People give bullion with different intensions according to these different speciality, and this promptly is the personal color of bullion.And the people of different makings if select the pendant bullion proper, then both can strengthen the personal color of bullion, the more charming glamour and the individual character of shapeable oneself, people and bullion are brought out the best in each other, enhance each other's beauty.

Tungstenalloy is applicable to the jewellery jewelry, and its product weight is heavy than common metal, makes the human consumer wear the weight sense, just as wearing precious metal deal is arranged, can be used for hardwares such as jewelry, bell table, jewellery, accessory, still, itself have frangible characteristic, be difficult to processing.

Summary of the invention:

The objective of the invention is at the deficiencies in the prior art, and a kind of tungsten alloy material of making jewellery is provided and makes the jewellery method, its surface-brightening is level and smooth, gives full play to the hardness and the brightness of tungsten, is not subjected to that burn into is colour-fast, non-friable, the surface is difficult for scratch.

For achieving the above object, the present invention adopts following technical scheme: its main component is tungsten (Tu), nickel (Ni), chromium (Cr), cobalt (Co), molybdenum (Mo), and the per-cent of each element is as follows: tungsten (Tu) 85%-88.5%, nickel (Ni) 5%-9.5%, chromium (Cr) 0.5%-3%, cobalt (Co) 1%-2%, molybdenum (Mo) 0.5%-3%.

It is characterized in that: the per-cent of described each element can be: tungsten (Tu) 86%, nickel (Ni) 9.45%, chromium (Cr) 2%, cobalt (Co) 2%, molybdenum (Mo) 0.55%.

Utilize tungsten alloy material making jewellery method steps to be:

(A), with the ratio allotment of powdered tungsten and other metal-powder according to claim 1 or claim 1, put into then and carry out even batch mixing in the cylinder.

(B), with the powder behind the uniform mixing, with the compacting or the injection moulding mode produce product basic configuration---idiosome.

(C), with idiosome 1 through the vacuum sintering mode, the dewaxing and sinter molding be workpiece, make workpiece density reach 14g/cm3, material metal hardness is HRA90.

(D), with the emery wheel, abrasive disc, the grinding tool that contain diamond or diamond alloy workpiece is carried out forming process.

(E), earlier metal works surface pore is beaten carefully, re-use mixtures such as diamond dust and grinding paster and carry out surface treatment, make workpiece surface be treated to minute surface with the cylinder mode.

Can under step (E), further be processed into finished product with edge down thing.

(A), the emery wheel that uses electrical spark, line to cut, contain diamond or diamond is played blind hole or fluting processing on workpiece.

(B), on diamond, quartzy external packets, have good ductile metal, the outside being surrounded by the diamond of metal, quartzy extruding or edge is embedded in the blind hole or groove in the above-mentioned steps.

Beneficial effect of the present invention is: its main component is tungsten (Tu), nickel (Ni), chromium (Cr), cobalt (Co), molybdenum (Mo), the per-cent of each element is as follows: tungsten (Tu) 85%-88.5%, nickel (Ni) 5%-9.5%, chromium (Cr) 0.5%-3%, cobalt (Co) 1%-2%, molybdenum (Mo) 0.5%-3%, the product of the tungsten manufacturing of this prescription 85%-88.5% can have the advantage of tungsten, firmly, bright, the product surface light that this prescription is produced is level and smooth, give full play to the hardness and the brightness of tungsten, and improve its frangible characteristic, specially be applicable to the jewellery jewelry, the surface does not have scratch or breach, have permanent advantage attractive in appearance, overcome the normal easily scratch of surface that takes place of traditional bullion material, be difficult for keeping the problem of permanent brightness.

Fig. 2 is the structural representation of workpiece of the present invention;

Fig. 3 is the structural representation of the embodiment of the invention one;

Fig. 4 is the structural representation of the embodiment of the invention two;

Fig. 5 is a sectional view of the present invention.

Embodiment:

See that Fig. 1 is to shown in Figure 5: a kind of alloy material of making jewellery of the present invention, its main component is tungsten (Tu), nickel (Ni), chromium (Cr), cobalt (Co), molybdenum (Mo), and the per-cent of each element is as follows: tungsten (Tu) 85%-88.5%, nickel (Ni) 5%-9.5%, chromium (Cr) 0.5%-3%, cobalt (Co) 1%-2%, molybdenum (Mo) 0.5%-3%.

Utilize tungsten alloy material making jewellery method steps to be:

(B), with the powder behind the uniform mixing, with the compacting or the injection moulding mode produce the product basic configuration---idiosome 1, as shown in Figure 1.

(C), with idiosome 11 through the vacuum sintering mode, the dewaxing and sinter molding be workpiece 2, make workpiece 2 density reach 14g/cm3, material metal hardness is HRA90.

(D), with the emery wheel, abrasive disc, the grinding tool that contain diamond or diamond alloy workpiece 2 is carried out forming process.

(E), earlier metal works 2 surperficial pores are beaten carefully, re-use mixtures such as diamond dust and grinding paster and carry out surface treatment, making workpiece 2 surface treatments is minute surface, as shown in Figure 2 with the cylinder mode.

(A), the emery wheel that uses electrical spark, line to cut, contain diamond or diamond beats

blind hole

11 or 12 processing of slotting on workpiece 2, show as Fig. 3,4.

(B), on diamond, quartzy 4 external packets, have good ductile metal 3, the outside being surrounded by the diamond of metal 3, quartzy 4 extruding or edge is embedded in the blind hole 11 or groove 12 in the above-mentioned steps, shown in the cross section among Fig. 5.

W content is high more, then its alloy material is hard more crisp more, the tungsten of this prescription 88% is the production limit, the product of manufacturing under this content, the advantage that can have tungsten, firmly, bright, and add special vacuum sintering technique, make its product be unlikely to frangible, the surface incandescent is close to minute surface, again since hardness near diamond, so how long no matter wear, or with other article side swipe, its product surface still light is level and smooth, does not have scratch or breach, has permanent advantage attractive in appearance, overcome the normal easily scratch of surface that takes place of traditional bullion material, be difficult for keeping the problem of permanent brightness, product weight is heavy than common metal, makes the human consumer wear the weight sense, just as wearing precious metal deal is arranged.

The present invention can make hardwares such as jewelry, bell table, jewellery, accessory.

The above only is preferred embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
