Abstract
The utility model relates to a drilling tool technical field discloses a percussion bit double angle alloy, including the drill bit body, the top position of drill bit body is equipped with vice cutting edge and main cutting edge, vice cutting edge position still is equipped with the chisel edge, vice cutting edge with main cutting edge is in different levels, the cutting angle of main cutting edge is compared the little 5-10 of cutting angle of vice cutting edge. The double-angle drill bit is provided, so that the drill bit is not easy to break teeth when meeting the steel bar during drilling, and the drilling is more stable and quick.
Description
Technical Field
The utility model relates to a drilling tool technical field indicates a percussion bit double angle alloy especially.
Background
The existing percussion bit tool bit alloy on the market has the design concept of only one cutting angle generally and single use function. When hitting the reinforcing bar during drilling, the easy emergence is cracked the tooth, is unfavorable for in-service use.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a percussion bit bi-angle alloy, its main objective is through the drill bit of design bi-angle, falls into vice cutting edge and main cutting edge, and the cutting angle of main cutting edge is less than the cutting angle of vice cutting edge, and during drilling, vice cutting edge can bump with the reinforcing bar in advance, avoids because the impact force is too big, and takes place to collapse the tooth.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a percussion bit double angle alloy, includes the drill bit body, its characterized in that: the drill bit comprises a drill bit body and is characterized in that an auxiliary cutting edge and a main cutting edge are arranged at the top end of the drill bit body, a chisel edge is further arranged at the auxiliary cutting edge, the auxiliary cutting edge and the main cutting edge are in different levels, and the cutting angle of the main cutting edge is 5-10 degrees smaller than that of the auxiliary cutting edge.
Further, the cutting angle of the secondary cutting edge is 135-145 °.
Further, the cutting angle of the main cutting edge is 130-140 °.
Furthermore, an inclined surface is arranged at the joint position of the main cutting edge and the side wall of the drill body.
The utility model discloses a set up the drill bit of double angle, touch the reinforcing bar when can effectively avoiding drilling and take place the condition of collapsing the tooth, simultaneously, the drilling of double angle is more quick and stable, can bear bigger impact force.

The reference numbers illustrate: 1. a drill bit body; 2. a secondary cutting edge; 3. a main cutting edge; 4. a chisel edge; 5. an inclined surface.
Detailed Description
Please refer to fig. 1-4, which are illustrations of the present invention, for the dual-angle alloy for percussion drill, comprising a drill body 1, the top end of the drill body is provided with an auxiliary cutting edge 2 and a main cutting edge 3, the auxiliary cutting edge 2 is further provided with a chisel edge 4, and the auxiliary cutting edge 2 and the main cutting edge 3 are at different levels.
In view of the drill bit on the present market adopts single cutting angle, the function is single, run into the reinforcing bar during drilling and easily take place to collapse the tooth, to this, the utility model discloses in provide a percussion bit double angle alloy, through set up vice cutting edge 2 and main cutting edge 3 on drill bit body 1, vice cutting edge 2 is located different levels with main cutting edge 3, the cutting angle of main cutting edge is little than the cutting angle of vice cutting edge, when drilling, vice cutting edge 2 drills in advance, then main cutting edge 3 redrilling, can improve more stably drilling and bore hole fast, when touchhing the reinforcing bar, the impact force that vice cutting edge 2 received is less, is difficult for taking place to collapse the tooth.
In a specific use, the cutting angle of the minor cutting edge 2 is 135-145 °. The preferred cutting angle is 140 °
The cutting angle of the main cutting edge 3 is 130-140 deg. The preferred cutting angle is 135 °. The cutting angle of the main cutting edge 3 is 5-10 degrees smaller than that of the auxiliary cutting edge 2, when the main cutting angle is smaller than the auxiliary cutting angle, drilling is carried out, the pressure of the main cutting angle is smaller during drilling, the drilling can be faster and more stable, and deviation can not occur.
As shown in fig. 1 and 3, an inclined surface 5 is provided at a position where the main cutting edge 3 meets the side wall of the drill body 1. The surface of many times's experimental result increases inclined plane 5 on the both ends position of main cutting edge 3 and drill bit body 1, when meetting the reinforcing bar at the in-process of drilling, can make the alloy bear bigger impact force, more is difficult for appearing collapsing the tooth.
The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
