Abstract
The utility model discloses a diamond carbide is compound top, including top body (1), there are cylindrical blind hole (2) in top body (1) upper end processing, interference fit has a diamond carbide is compound top piece in cylindrical blind hole (2) of top body, the diamond carbide is compound top piece includes and cemented carbide substrate (3) is provided with diamond layer (4) on cemented carbide substrate (3). The utility model discloses the wear -resisting body of diamond carbide is compound top material had both had the high rigidity of diamond, had carbide's high strength again, therefore can improve apical life greatly, was 100~200 times of top life -span of carbide, because the interference fit equipment, the top body of having avoided bringing because of the welding is annealed, reduces top bulk strength and rigidity and descends, is favorable to the improvement of machining precision. Because point portion is spherical, can avoid the injury to the people.
Description
Technical field
The utility model relates to mechanical field, and especially diamond hard alloy is compound top.
Background technology
Tradition is top is generally welded in top body end with carbide alloy, but its wearability is poor, and the life-span is short. And someDiamond is top or weld on top body taking dimond synneusis as wear body or with diamond compact. TheyAll there is the hidden danger that bulk strength is low or wearability is not high enough.
Utility model content
Order of the present utility model is, for above-mentioned the deficiencies in the prior art, to provide a kind of diamond hard alloy compound topPoint, this is top not only high wearability, also has higher intensity. Thereby can greatly improve top service life,100 ~ 200 times of carbide-tipped center life-span.
Compound top the adopted technical scheme of the utility model diamond hard alloy is as follows:
The utility model diamond hard alloy is compound top, comprises top body, is processed with circle in top body upper endPost blind hole, in the cylinder blind hole of top body, interference fit has compound top of diamond hard alloy, and described diamond is hardCompound top of matter alloy comprises hard alloy substrate, is provided with diamond layer on hard alloy substrate.
As preferred version of the present utility model, described hard alloy substrate comprises cylinder pedestal, at cylinder pedestalOn be provided with circular cone stage body top tip part, be provided with spherical crown at the top of circular cone stage body top tip part, diamond layer is wrapped in the frustum of a coneOn body top tip part and spherical crown.
As preferred version of the present utility model, described hard alloy substrate comprises the cylindrical base with tapering, in cylindricalityOn pedestal, be provided with circular cone stage body top tip part, be provided with spherical crown at the top of circular cone stage body top tip part, diamond layer is wrapped in circleOn cone table top tip part and spherical crown. As preferred version of the present utility model, the tapering of the described cylindrical base with tapering is 0.5~3°。
As preferred version of the present utility model, the tapering of described circular cone stage body top tip part is 60 °.
As preferred version of the present utility model, the R of described spherical crown is 0.2-2mm.
As preferred version of the present utility model, described diamond layer is polycrystalline diamond composite bed.
The compound top beneficial effect of the utility model diamond hard alloy is as follows:
1, the compound top wear body material of diamond hard alloy had both had adamantine high rigidity, had again carbide alloyHigh strength, thereby can greatly improve top service life, be 100 ~ 200 times of carbide-tipped center life-span;
2, due to interference fit assembling, avoided the top body annealing that brings because of welding, reduce top bulk strength andRigidity declines, and is conducive to the raising of machining accuracy.
3, because tip is spherical, can avoid the injury to people.

Detailed description of the invention
The utility model diamond hard alloy is compound top, comprises top body 1, is processed with in top body 1 upper endCylinder blind hole 2, has compound top of diamond hard alloy in the interior interference fit of cylinder blind hole 2 of top body. Due to topThe compound top interference fit assembling of body and diamond hard alloy, has avoided the existing top body bringing because of welding to move backFire, reduces the problem that top bulk strength and rigidity decline, thereby has improved machining accuracy, has ensured compound top product productMatter.
Compound top of diamond hard alloy comprises hard alloy substrate 3, on hard alloy substrate 3, is provided with Buddha's warrior attendantStone layer 4. Described diamond layer 4 is preferably polycrystalline diamond composite bed. By by diamond sintering on hard alloy substrate, makeObtain compound top of diamond hard alloy and both there is adamantine high rigidity, there is again the high strength of carbide alloy, thereby canGreatly to improve top service life, be 100 ~ 200 times of ordinary rigid alloy centre life-span in the past.
The structure of hard alloy substrate can, for comprising cylinder pedestal 3-1, be provided with circular cone on cylinder pedestal 3-1Stage body top tip part 3-3, is provided with spherical crown 3-4 at the top of circular cone stage body top tip part 3-3, and diamond layer 4 is wrapped in circular cone stage bodyOn top tip part 3-3 and spherical crown 3-4. The tapering of described circular cone stage body top tip part 3-3 is 60 °, and the R of spherical crown 3-4 is 0.2-2mm. ByInterference fit between diamond hard alloy compound top and top body 1, cylinder pedestal is a bit larger tham top body 1On cylinder blind hole 2 apertures, when install time, first top body 1 is heated, cylinder blind hole 2 apertures are added by the principle of heat expansionGreatly, then insert cylinder pedestal 3-1, after top body is cooling, formation closely cooperates.
The structure of hard alloy substrate can be also the cylindrical base 3-2 comprising with tapering, the described cylindricality base with taperingThe tapering of seat 3-2 is 0.5 ~ 3 °. On cylindrical base 3-2, be provided with circular cone stage body top tip part 3-3, at circular cone stage body top tip part 3-3 top is provided with spherical crown 3-4, and diamond layer 4 is wrapped on circular cone stage body top tip part 3-3 and spherical crown 3-4. Described circular cone stage bodyThe tapering of top tip part 3-3 is 60 °, and the R of spherical crown 3-4 is 0.2-2mm. By the cylindrical base 3-2 with tapering is set, so notNeed to heat in advance top body 1, can directly insert and be installed in cylinder blind hole 2 by tapering.
