Abstract
The utility model discloses a Y font percussion bit, including boring the core, there is three percussion drill piece at the side integrated into one piece of boring the core, and three percussion drill piece constitutes Y font structure with boring the core, has the drill point at the end fixing of boring the core, is provided with slope guide gusset between the tip of drill point and percussion drill piece, offers the drain rake groove that is used for guiding the refrigeration liquid on percussion drill piece's side, and it is protruding that there is triangle-shaped for slope setting and integrated into one piece at percussion drill piece's top surface, and the bellied outer corner of triangle-shaped sets up for the arc. The utility model discloses a structure sets up rationally, and it is provided with three impact drill piece to can improve the scope of assaulting, be provided with the drain inclined groove in the side of impacting the drill piece simultaneously, from when having the refrigerant liquid, also can directly guide the drill point from the drain inclined groove, be favorable to dispelling the heat to the brill dirt, thereby improve the life-span of using, it is provided with slope guide gusset simultaneously, also can guarantee the use reliability and stability of drill point, and the suitability is strong and the practicality is good.
Description
Technical Field
The utility model belongs to the technical field of the drill bit, concretely relates to Y font percussion bit.
Background
Percussion bit is a common structure, and percussion bit's of prior art drill bit main part adopts cylinder or a font main part more, and it can satisfy the user demand of general condition, but in the in-service use in-process, percussion bit can be strikeed and produce a large amount of heats, uses for a long time because be unfavorable for the heat dissipation and very easy damage, can influence the effect of impact moreover, so suitability and practicality receive the restriction.
Disclosure of Invention
The utility model aims at providing a structure sets up reasonable and the Y font percussion bit that the suitability is strong.
Realize the technical scheme of the purpose is that a Y font percussion bit, including boring the core the side integrated into one piece of boring the core has three impact to bore the piece, and three impact bores the piece and bores the core and constitutes Y font structure the end fixing of boring the core has the drill point with be provided with slope guide gusset between the tip of impact drill piece set up the drain inclined groove that is used for guiding the refrigeration liquid on the side of impact drill piece the top surface of impact drill piece sets up and integrated into one piece has triangle-shaped protruding for the slope, just the bellied outer corner of triangle-shaped sets up for the arc.
The outer edges of the three percussion drill bits are positioned on a circular ring with the diameter of 11.85 mm.
The total height of the drill point and the drill core is 8 mm.
The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, and it is provided with three impact drill piece to can improve the scope of assaulting, be provided with the drain inclined groove in the side of impacting the drill piece simultaneously, from when having the refrigerant liquid, also can directly guide the drill point from the drain inclined groove, be favorable to dispelling the heat to the brill dirt, thereby improve the life-span of using, it is provided with slope guide gusset simultaneously, also can guarantee the use reliability and stability of drill point, and the suitability is strong and the practicality is good.
Drawings
