Abstract
The present invention is a techniaue of drawing die insert welding with natural diamond.Invention proposes to use that (P-Fe) waits main body powder that metal dust constitutes and is pre-pressed into the mould post and natural diamond, chromium nickel stainless steel die sleeve welding-on are in the same place by the top powder of nickel (Ni), titanium (Ti), tungsten (W), copper (Cu), tin (Sn), cobalt (Co), plumbous formation such as (Pb) metal dust, makes the new type natural dimaond die by nickel (Ni), tungsten (W), copper (Cu), tin (Sn), plumbous (Pb), cobalt (Co), ferrophosphorus.Technology of the present invention is simple, and is easy to operate, and the wire drawing die quality of making is good, the life-span is long.In case promote aborning and utilize, will save a large amount of natural diamonds and fund.
Description
The present invention is a techniaue of drawing die insert welding with natural diamond, belongs to the forming tool of metal drawing, the combination of wire drawing die and axle.
The natural diamond wire drawing die is the mould that metal stock is drawn into a material by means of the hole of diamond.Natural diamond among the die sleeve of wire drawing die whether fixing strong be wire drawing die quality quality, service life length key.The present both at home and abroad diamond fixing means of natural diamond wire drawing die commonly used has brass to inlay method, powder metallurgy inlays method, casting etc.Their essence all is that machinery inlays, i.e. the effect of expanding with heat and contract with cold by metal fixes diamond in the die sleeve of wire drawing die.There is the slit between diamond in this natural diamond wire drawing die and the metal, in use easily loosening, cracked even come off; The metal pair die sleeve does not have welding effect, Yi Songtao.Therefore wire drawing die is of poor quality, and service life is low.
The objective of the invention is to improve this wire drawing die that fixes natural diamond by machinery, therefore propose to use the main body powder that constitutes by nickel (Ni), tungsten (W), copper (Cu), tin (Sn), plumbous (Pb), cobalt (Co), ferrophosphorus (P-Fe) metal dust of etc.ing and give by the top powder of nickel (Ni), titanium (Ti), tungsten (W), copper (Cu), tin (Sn), cobalt (Co), plumbous formation such as (Pb) metal dust and to be pressed into the mould post and natural diamond, chromium nickel stainless steel die sleeve welding-on are in the same place, make the new type natural dimaond die.Natural diamond in this wire drawing die not only receives the stress effect of giving of machinery fixing, and the top powder section of diamond and mould post, and the main body powder section of chromium nickel stainless steel die sleeve and mould post also has the welding-on effect.Be chemical bond between top powdered metallurgical material and the diamond, formed an adhesive linkage.Diffusion owing to nickle atom between same main body powdered metallurgical material and the chromium nickel stainless steel die sleeve has also produced bonding effect.And the main body powdered metallurgical material of mould post and top powdered metallurgical material fuse into one in hot pressing, and like this, natural diamond, mould post, chromium nickel stainless steel die sleeve are just fixed as a whole firmly.This new type natural dimaond die diamond at work is not loosening; The not loose cover of mould post and die sleeve; The friction heat that produces on the natural diamond during drawing silk material is very fast to be scattered and disappeared, and makes unlikely graphitization of diamond or scaling loss.
Therefore the natural diamond wire drawing die life-span made from the present invention is long; The silk material that still can be used for another big specification of drawing after repeatedly reprocessing is used; Wire drawing die with the big specification of natural diamond raw material manufacturing of small dimension.
Technology of the present invention is simple, easy to operate, and without graphite mo(u)ld, heat time heating time is short, without protective atmosphere, from you save time, laborsaving, economical.
On current international market, the natural diamond price soars, and under the more expensive situation of bulky grain natural diamond, popularization of the present invention and application will be saved a large amount of diamonds and fund for country.
Natural diamond wire drawing die welding-on of the present invention technological process is as follows:

The hot pressing welding-on
The metal dust percentage by weight that constitutes mould post main body meal component is as follows: tungsten (W) 10～20%, and copper (Cu) 11～18%, tin (Sn) 8～10%, cobalt (Co) 3～4%, plumbous (Pb) 6～7%, ferrophosphorus (P-Fe) 2～5%, surplus is nickel (Ni).
The metal dust percentage by weight that constitutes mould column top meal component is: brocade (Ni) 1～3%, and titanium (Ti) 10～20%, tungsten (W) 20～30%, tin (Sn) 6～8%, cobalt (Co) 1～3%, plumbous (Pb) 1～6%, surplus is copper (Cu).
The granularity of above-mentioned each metal dust is all in 200 orders～300 order scopes; Its purity is more than 99.5%; Wherein Cu, Co, three kinds of metal dusts of Ni will be handled through reduction.Main body powder and top powder are evenly mixed separately,, weigh up needed main body powder and top powder weight separately according to the size of wanting the molding post.The weight ratio of main body powder and top powder is in 12～4 scope.Earlier the main body powder is packed into and give in the punching block of molding post, again the top powder is poured into, be pressed into the mould post adding then.Its profile can be a Cylinder, can also be the polygon cylinder that has three limits at least.The shape of the nib in the chromium nickel stainless steel die sleeve, size should be complementary with shape, the size of mould post cross-sectional area.Give the position that fixes natural diamond earlier with bonding method in nib, then the mould shell of column that is made of the top powder is placed nib facing to natural diamond, the mould post will exceed the die sleeve plane at least more than the 1mm.Give die sleeve, the heating of mould post with the medium-high frequency induction furnace, when the temperature of mould post reaches 890 ℃ ± 20 ℃, give the pressurization of mould post, up to mould styletable face and die sleeve end face.The hot pressing overall process is 20～60 seconds.
Inventive embodiment, as follows by means of description of drawings.
Fig. 1: mould post
Fig. 2: the wire drawing die semi-finished product that natural diamond, mould post, die sleeve welding-on do not punch together as yet.
Select for use the main body flour gold to belong to powder and the top flour gold belongs to powder by following percentage by weight.The main body powder: tungsten (W) 15%, copper (Cu) 13.5%, tin (Sn) 8.2%, cobalt (Co) 2%, plumbous (Pb) 6.3%, ferrophosphorus (P-Fe) 1.0%, surplus is nickel (Ni); The top powder: nickel (Ni) 1.6%, titanium (Ti) 14.4%, tungsten (W) 22.2%, tin (Sn) 7%, cobalt (Co) 1.8%, plumbous (Pb) 3%, surplus is copper (Cu).The granularity of above-mentioned each metal dust is all in 200 orders～300 order scopes; Its purity is more than 99.5%; Wherein copper, cobalt, three kinds of metal dusts of nickel will be handled through reduction.Main body powder and top powder are evenly mixed separately, weigh up main body powder 3.2 grams, powder 0.4 gram in top is packed the main body powder in the garden cylindricality punching block that gives the molding post into earlier, the top powder is poured into, then pressurization 200 kilograms per centimeter on forcing press again
2Become the garden cylindricality after mould post (6) demoulding.It is made up of main body powder mould shell of column (1) and top powder mould shell of column (2).
Be processed into die sleeve (3) with the OCr18Ni9 stainless steel, middle nib (5) bottom that diamond (4) sticks with glue at die sleeve.Die throat diameter φ 10mm, degree of depth 4.5mm.Then the mould post is put into nib by the mould shell of column that the top powder forms facing to natural diamond, at this moment the mould post exceeds the die sleeve end face at least more than the 1mm.Give die sleeve, 10 kilowatts of high-frequency electrical of the heating of mould post with induction heating furnace, 890 ℃ of of of when the mould column temperature reaches, give mould post plus-pressure 6 kilograms per centimeter2Up to mould post and die sleeve end face.The hot pressing overall process is 35 seconds.
