Abstract
The utility model discloses a wire drawing die for wrapping a diamond high temperature sintering body. The die core of the wire drawing die comprises a die shell, a gland, a metal sintering block and diamond particles, wherein the metal sintering block is inlaid in the die shell, the gland is arranged at the top of the metal sintering block, the gland is flush with the die shell, the diamond particles are embedded into the metal sintering block and are arranged at the center of the die shell, and a die hole is formed at the center of the metal sintering block. The wire drawing die for wrapping the diamond high temperature sintering body has the advantages that materials, namely bronze, zinc, manganese and tungsten metal particles in different contents, for wrapping small diamond particles are added into a nickel base, strength and rigidity of diamond are guaranteed and toughness is also improved when the die is used; when sintering, an appropriate precompression stress is applied to a diamond die core, further toughness of the die core is improved, die repairing frequency is increased to 5-10 times, and cost is also reduced to one tenth of the original cost.
Description
Technical field
The utility model relates to a kind of dimaond die, in particular a kind of wire drawing die that wraps up diamond high temperature sintering body.
Background technology
Dimaond die has two kinds, and a kind of is the natural diamond wire drawing die, and another kind is the man-made polycrystalline diamond wire drawing die.Natural diamond has the advantages that hardness is high, wearability is good; the wire surface fineness drawn is very high; because natural diamond structurally has anisotropy; cause its hardness also to present anisotropy; make the wearing and tearing of nib inhomogeneous, goods are rounding not, in addition expensive, rare; its, deviation was very large in service life, generally as surface quality, required high fine rule wire drawing die or finished product wire drawing die.Man-made polycrystalline diamond is unoriented polycrystal, has hardness high, and wearability is good, the advantage of strong shock resistance.There do not is anisotropy on hardness, even wearing, die life is long, be subject to the favor of wire drawing die producer, but no matter be natural diamond or polycrystalline diamond, fragility is all larger, in drawing process, easily ftracture, this is the focus and emphasis of wire drawing die industry research.For this reason, scrappage how to control wire drawing die becomes the development trend of wire drawing die industry.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of wire drawing die that wraps up diamond high temperature sintering body is provided, and improves the quality of wire drawing die, improves the mould repair number of times.
The utility model is achieved through the following technical solutions, the core rod of wire drawing die described in the utility model comprises formwork, gland, metal sintering piece and diamond particles, described metal sintering piece is embedded in formwork, gland is positioned at the top of metal sintering piece, gland is concordant with formwork, diamond particles is embedded on the metal sintering piece and is positioned at the center of formwork, and described metal sintering Kuai offers nib in center.
The bottom of described metal sintering piece and diamond particles forms anti-mouthful, 15% of the core rod height that the height of described anti-mouthful is wire drawing die.
As one of optimal way of the present utility model, described formwork is the stainless steel formwork.
The utility model has the following advantages compared to existing technology: the utility model wraps up the adamantine material of broken granule at metallic particles such as the bronze of Ni-based middle interpolation different content, zinc, manganese, tungsten, reach mould and both guaranteed in use adamantine intensity, rigidity, improved again toughness; During sintering, the diamond core rod is applied to appropriate compressive pre-stress, further improve core rod toughness, the mould repair number of times is brought up to 5～10 times, and cost also is reduced to original 1/10.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is diamond preloading stress and direct stress schematic diagram.
The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, the core rod of the wire drawing die of the present embodiment comprises formwork 1, metal sintering piece 2, gland 5 and diamond particles 3, described metal sintering piece 2 is embedded in formwork 1, gland 5 is positioned at the top of metal sintering piece 2, gland 5 is concordant with formwork 1, diamond particles 3 is embedded on metal sintering piece 2 and is positioned at the center of formwork 1, and nib 4 is offered at the center of described metal sintering piece 2.The formwork 1 of the present embodiment is the stainless steel formwork.The bottom of metal sintering piece 2 and diamond particles 3 forms anti-mouthful 6,15% of the core rod height that the height of described anti-mouthful 6 is wire drawing die.
The preparation method of the present embodiment wire drawing die comprises the following steps:
(1) the part mixed metal powder is put into to stainless steel formwork 1, cover gland 5, compaction on sintering press, take out gland 5;
(2) a minimum particle diamond particle 3 is bonded in to the center of the metal-powder of compacting in stainless steel formwork 1, the diamond particles of the present embodiment is 0.02 carat, and effectively the diameter of overlapping area is 0.5mm;
(3) remaining mixed metal powder is put into to stainless steel formwork 1, cover gland 5, carry out the high temperature sintering compacting putting on sintering press, described mixed metal powder comprises W25%, Fe3%, Cu25%, Ni25%, Cr10%, Mn7%, Sn5%;
The stainless steel formwork 1 that has added mixed metal powder is heated, keep temperature-resistant after being heated to 900 ℃, exert pressure in the time of heating, be heated to after design temperature and be pressurized to 4.5MPa and then keep pressure constant, the time of heating pressurization is 3min.
(4) then go out taper hole by car successively, laser boring, punch and make wire drawing die in stainless steel formwork 1 center of Finish Machining Bore after to sintered compact.
Wire drawing die of the present utility model is first to heat afterwards and pressurize in sintering process, can realize that like this lower pressure makes formwork 1 distortion of wire drawing die, makes part metals in metal dust reach its fusing point fusing simultaneously, thereby can infiltrate diamond particles 3.Metal dust applies appropriate compressive pre-stress F ' to diamond particles 3 in sintering process, can balance out or offset the direct stress F of 7 pairs of die walls of a part of steel wire in drawing process, as shown in Figure 2.While owing to having certain toughness, while in drawing process, being subject to impulsive force, is also played certain cushioning effect to diamond particles 3 in the metal sintering piece 2 at anti-mouthful 6 places, thereby reduces the tearing tendency of diamond particles 3, improves the mould repair number of times.
