Abstract
The utility model discloses a hard alloy anti-skidding flat tooth. The flat tooth (1) is cast by a die, and a tooth top (2) and anti-skidding strips are arranged on the flat tooth (1). According to the design of the flat tooth, the anti-skidding strips are designed on a tooth body of the flat tooth, the flat tooth can be well prevented from loosening or dropping off when the hard alloy anti-skidding flat tooth is in operation, and accordingly the flat tooth is firmly installed at the top of a drill bit, and the service life of the flat tooth is prolonged.
Description
Technical field:
The utility model relates to the anti-skidding tack tooth of carbide alloy above a kind of storehouse body that is arranged on rock drill.
Background technology:
The design of present tack tooth, its tooth body does not all design reeding, and the tooth body of tack tooth is smooth arc surface, walks because violent vibrations are prone to during operation, becomes flexible the situation that causes the tack tooth to occur dropping.
Summary of the invention:
Goal of the invention of the present utility model is to be prone in order to overcome the tack tooth difficulty that walks, becomes flexible, and provides a kind of carbide alloy anti-skidding tack tooth.
The utility model is to adopt following technical scheme to realize its goal of the invention: the anti-skidding tack tooth of a kind of carbide alloy, it casts tack tooth 1 by mould, and be provided with tooth top 2 on tack tooth 1, reeding 3; Tooth top 2 is located at the top of tack tooth 1; Reeding 3 is located at the tooth body outer ring of tack tooth 1.
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 tack tooth, can prevent preferably the tack loose compact during operation, drop, thereby make the tack tooth firmly be arranged on drill bit top, the application life of having improved the tack tooth.
Description of drawings:
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, the anti-skidding tack tooth of a kind of carbide alloy, it casts tack tooth 1 by mould, and be provided with tooth top 2 on tack tooth 1, reeding 3; Tooth top 2 is located at the top of tack tooth 1; Reeding 3 is located at the tooth body outer ring of tack tooth 1.
Tooth top 2 described in the utility model refers to: the carbide alloy tooth top by mould is cast, be global design with tack tooth 1, and be tack tooth 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.
