The utility model discloses effectively improved the holding capacity, prevented its fracturing to more do benefit to and synthesize with the diamond, improve the synthetic qualification rate of product.
Description
Technical Field
The utility model relates to an oil drilling drill bit auxiliary field, concretely relates to with the supporting base member of the compound piece of carbide who uses of oil drilling drill bit.
Background
The hard alloy composite sheet used in conjunction with oil drilling bit is mainly made of integral hard alloy, and the matrix is made up by using powder direct pressing and forming process, and its synthetic surface is compounded with diamond powder.
In the prior art, the matrix is a cylindrical block, the top surface of the matrix is a synthetic surface, the synthetic surface is provided with V-shaped grooves, the bearing capacity of the groove surface is limited, the fracturing is easy, and the synthetic effect of the diamond powder is still insufficient.
Disclosure of Invention
The utility model aims at providing an oil is with compound piece base member of hard alloy for probing drill bit improves the holding capacity of base member, does benefit to and synthesizes with the diamond.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a hard alloy composite sheet matrix for an oil drilling bit is characterized in that a main body is a cylindrical block, one axial end face of the cylindrical block is a synthetic surface, and a groove is formed in the synthetic surface;
the groove comprises a plurality of annular grooves and a plurality of radial grooves; the annular grooves are formed around the circumference of the synthetic surface, and the annular grooves are concentrically arranged around the center of the synthetic surface so as to form a plurality of annular ribs on the synthetic surface; the radial grooves are formed along the radial direction of the synthetic surface, a plurality of radial grooves are uniformly arranged on each annular rib at intervals, and the radial grooves on adjacent annular ribs are staggered; the cross sections of the annular groove and the radial groove are both arc-shaped.
In the above aspect, when viewed in an axial cross section of the base, a projection of a top surface of the outermost annular rib is formed in a frustum shape, and a projection of a groove bottom surface of the radial groove in the outermost annular rib is also formed in a frustum shape.
The utility model discloses theory of operation and advantage as follows:
the utility model discloses effectively improved the holding capacity, prevented its fracturing to more do benefit to and synthesize with the diamond, improve the synthetic qualification rate of product.

Detailed Description
The invention will be further described with reference to the following drawings and examples:
example (b): referring to FIGS. 1-4:
a hard alloy composite sheet matrix for an oil drilling bit is a cylindrical block, one axial end face of the matrix is a synthetic face 1, and a groove is formed in the synthetic face 1. The grooves comprise a plurality of annular grooves 2 and a plurality of radial grooves 3.
Referring to fig. 1 to 4, the annular grooves 2 are formed around the circumference of the synthetic surface 1, and a plurality of annular grooves 2 are concentrically arranged around the center of the synthetic surface 1, so that a plurality of annular ribs 4 are formed on the synthetic surface 1. The radial grooves 3 are grooves formed in the radial direction of the synthetic surface, the radial grooves 3 are uniformly arranged on each annular rib-shaped body 4 at intervals, and the radial grooves 3 on the adjacent annular rib-shaped bodies 4 are staggered.
Referring to fig. 1 to 4, the cross sections of the annular groove 2 and the radial groove 3 are both arc-shaped, as shown in fig. 4.
Referring to fig. 1 to 4, when viewed in an axial cross section of the base, a top surface of the outermost annular rib 4 is projected to be a frustum shape, and a bottom surface of the radial groove 3 of the outermost annular rib 4 is projected to be a frustum shape.
The embodiment effectively improves the bearing capacity of the matrix, prevents the fracturing of the matrix, is more beneficial to the synthesis of diamond and improves the synthesis qualification rate of products.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention.
