Abstract

The utility model discloses an antiskid sphere tooth designed on a hard alloy. According to the antiskid sphere tooth designed on the hard alloy, a sphere tooth (1) is cast through a casting mold, and a tooth top (2) and an antiskid strip (3) are arranged on the sphere tooth (1). Due to the fact that the antiskid strip is designed on a tooth body of the sphere tooth, the sphere tooth can be well prevented from loosing and falling in working, and accordingly the sphere tooth can be stably installed at the top of a drilling head, and service life of the sphere tooth is improved.

Description

Design nonskid ball shape tooth on a kind of carbide alloy
Technical field:
The utility model relates to design nonskid ball shape tooth on carbide alloy above a kind of storehouse body that is arranged on rock drill.
Background technology:
The design of present hemi-spherical ended shape insert, its tooth body does not all design reeding, and the tooth body of hemi-spherical ended shape insert is smooth arc surface, walks because violent vibrations are prone to during operation, becomes flexible the situation that causes hemi-spherical ended shape insert to occur dropping.
Summary of the invention:
Goal of the invention of the present utility model is to be prone in order to overcome hemi-spherical ended shape insert the difficulty that walks, becomes flexible, and design nonskid ball shape tooth on a kind of carbide alloy is provided.
The utility model is to adopt following technical scheme to realize its goal of the invention: design nonskid ball shape tooth on a kind of carbide alloy, it casts hemi-spherical ended shape insert 1 by mould, and be provided with tooth top 2 on hemi-spherical ended shape insert 1, reeding 3; Tooth top 2 is located at the top of hemi-spherical ended shape insert 1; Reeding 3 is located at the top of hemi-spherical ended shape insert 1 tooth body outer ring.
The utility model is set as 2.5:1 to tooth body diameter 4 and outside pitch line length 5 dimension scale both of hemi-spherical ended shape insert 1 in order to realize the friction function of hemi-spherical ended shape insert and rock.
Realize preferably its goal of the invention owing to having adopted above technology the utility model, reeding in the design of the tooth body of hemi-spherical ended shape insert, can prevent better during operation that hemi-spherical ended shape insert from becoming flexible, dropping, thereby make hemi-spherical ended shape insert firmly be arranged on drill bit top, the application life of having improved hemi-spherical ended shape insert.
Description of drawings:
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
Accompanying drawing 2 is section constructed profiles of the present utility model.
Accompanying drawing 3 is upper plane structure schematic diagrames of the present utility model.
Description of reference numerals is seen manual last page form.
The specific embodiment:
Below in conjunction with accompanying drawing, summary of the invention is described further:
Embodiment 1:
By accompanying drawing as can be known, design nonskid ball shape tooth on a kind of carbide alloy, it casts hemi-spherical ended shape insert 1 by mould, and be provided with tooth top 2 on hemi-spherical ended shape insert 1, reeding 3; Tooth top 2 is located at the top of hemi-spherical ended shape insert 1; Reeding 3 is located at the top of hemi-spherical ended shape insert 1 tooth body outer ring.
The utility model is set as 2.5:1 to tooth body diameter 4 and outside pitch line length 5 dimension scale both of hemi-spherical ended shape insert 1 in order to realize the friction function of hemi-spherical ended shape insert and rock.
Hemi-spherical ended shape insert 1 described in the utility model refers to: by the sintering skin of cemented carbide tooth that mould is cast, which is provided with tooth top 2, reeding 3; Its structure as shown in Figure 1, its section is as shown in Figure 2.
Tooth top 2 described in the utility model refers to: the carbide alloy tooth top by mould is cast, be global design with hemi-spherical ended shape insert 1, and be hemi-spherical ended shape insert 1 part; Its effect is directly to contact and carry out operation with drilled thing (as: boring the ground stone, open the oil field); Its design attitude is as shown in mark in Fig. 12, and its section is as shown in mark 2 in accompanying drawing 2.
Reeding 3 described in the utility model refers to: the carbide alloy reeding 3 by mould is cast, be global design with hemi-spherical ended shape insert 1, and be hemi-spherical ended shape insert 1 part; Its design is in the tooth body of hemi-spherical ended shape insert 1; Play a part anti-skidding when operation; Its design attitude is as shown in mark in Fig. 13, and its section is as shown in mark 3 in accompanying drawing 2.
Tooth body diameter 4 described in the utility model refers to: the base diameter of hemi-spherical ended shape insert tooth body; Described tooth body refers to not contain the length of reeding 3 parts.
Outside pitch line length 5 described in the utility model refers to: the height of tooth top 2.
Upper design in denomination of invention described in the utility model " design nonskid ball shape tooth on a kind of carbide alloy " refers to: reeding 3 designs are in the tooth body of hemi-spherical ended shape insert 1.
