Abstract
The utility model discloses a diamond compact substrate which is composed of a bottom face, a combination face and a cylindrical face for connecting the bottom face with the combination face. The combination face is composed of an annular conical face body, a central circular plane and a plurality of pyramid-shaped small convex teeth evenly distributed on the central circular plane. Each pyramid-shaped small convex tooth is characterized in that a small convex spherical surface is orthogonally tangent with four large concave spherical surfaces, and every two intersected edges of the tangent curved surfaces are all rounded. By means of the diamond compact substrate, the effective combination area is maximized, the combination strength is high, and the high stripping resistant capacity and the high impact resistant capacity are achieved; meanwhile, the mold manufacturing technology is practicable, the compression molding performance is good, and the surface accuracy is high.
Description
Technical field
The utility model relates to a kind of diamond compact substrate, relates in particular to the composite surface structure contacting with diamond.
Background technology
The hard alloy substrate that this project relates to is combined with diamond and is formed composite sheet, and its existing adamantine hardness and wear resistance, has again the impact resistance of carbide alloy and the feature of weldability, is mainly used in the industries such as oil and geological drilling.In order to improve the combined strength bination of diamond and hard alloy substrate, the same industry is on composite surface, to attempt designing various tooth-shape structures at matrix surface both at home and abroad.The composite surface of general composite sheet matrix is generally all comprised of a belt plane Yu Yi garden platform, and round platform is divided into various flute profiles: striated, latticed, square shape, radial etc.But complex-shaped flute profile, if the design of flute profile layout and tooth parameter is unreasonable, cutter or interfere or breaking and cause mould to process in the time of may causing processing mold electrode; Also may cause the compressing poor performance of product, cannot compression molding, or mold pressing is of poor quality, qualification rate is low.
Utility model content
Diamond compact substrate of the present utility model, for above-mentioned deficiency, provides a kind of different composite surface structure, and the effective compound area of matrix is maximized, and combined strength bination is higher, has stronger anti-strip and impact resistance; Simultaneously grooved parameter designing is reasonable, and not only Mold Making feasible process can time processing moulding, and can guarantee high-precision surface quality, meets the production requirement of compression molding.
Diamond compact substrate of the present utility model, is comprised of bottom surface, composite surface on the other side and the face of cylinder that connects above-mentioned bottom surface and composite surface; Described composite surface is comprised of the uniform little double wedge of some pyramid shapes in a belt taper seat, central circular plane, circular plane.
The little double wedge of described pyramid shape is tangent by the small sphere of exterior rearview of a protrusion and four the recessed large spheres face face that is orthogonal, crossing whole roundings of seamed edge between two between each phase tangent surface.Be convenient to like this processing and the demoulding.
The small sphere of exterior rearview radius r of the little double wedge of described pyramid shape is 0.1~0.35mm, and large spherical radius R is 0.5~1.0mm, and seamed edge chamfering radius is 0.1~0.35mm; The tooth depth h of little double wedge is 0.4~0.7mm, and space width m is 1.0~2.0mm.Grooved parameter designing is reasonable, not only can time processing moulding, and can meet the production requirement of compression molding, matrix and diamond combined strength bination are high simultaneously, have stronger anti-strip and impact resistance.
The angle δ of the described belt taper seat conical surface is 20 ~ 30 °, the poor φ D-of the upper and lower diameter of conical surface φ d >=2mm.Parameter designing is reasonable, meets matrix and the requirement of diamond compound use.
The composite surface edge of diamond compact substrate of the present utility model is that a belt taper seat, central authorities are several pyramidion shape double wedges that are evenly being scattered in a circular plane.The geometry of this uniqueness, flute profile is rationally distributed, attractive in appearance, and grooved parameter designing is reasonable, and not only mould processing technology is feasible, can time processing moulding, and can guarantee high-precision surface quality, meet the production requirement of compression molding; Matrix and diamond combined strength bination are high simultaneously, have stronger anti-strip and impact resistance.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, diamond compact substrate of the present utility model, bottom surface 1, composite surface on the other side 3 and the face of cylinder 2 that connects above-mentioned bottom surface and composite surface, consist of, composite surface 3 is comprised of the uniform little double wedge 33 of several pyramid shapes in taper seat 31, central circular plane 32, circular plane 32 that goes in ring.
As in Figure 2-4, the little double wedge 33 of each pyramid shape is tangent by the small sphere of exterior rearview of a protrusion and four the recessed large spheres face face that is orthogonal, crossing whole roundings of seamed edge between two between each phase tangent surface.Small sphere of exterior rearview radius r is 0.1~0.35mm, and large spherical radius R is 0.5~1.0mm, and seamed edge chamfering radius is 0.1~0.35mm; The tooth depth h of little double wedge is 0.4~0.7mm, and space width m is 1.0~2.0mm.
As shown in Figure 3, the conical surface angle δ of the taper seat 31 that goes in ring is 20 ~ 30 °, the poor φ D-of the upper and lower diameter of conical surface φ d >=2mm.
The composite surface edge of diamond compact substrate of the present utility model is that a belt taper seat, central authorities are several pyramidion shape double wedges that are evenly being scattered in a circular plane, rationally distributed, attractive in appearance, grooved parameter designing is reasonable, not only mould processing technology is feasible, can time processing moulding, and can guarantee high-precision surface quality, meet the production requirement of compression molding; Matrix and diamond combined strength bination are high simultaneously, have stronger anti-strip and impact resistance.
