Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1, the tungsten steel drill bit with self-centering positioning of the present invention comprises a fixing portion 1 connected to a drilling machine and a cutting portion 2 for drilling, wherein a protruding positioning portion 3 is disposed at the end of the cutting portion 2 away from the fixing portion 1, and the positioning portion 3 is used for positioning the drill bit for drilling; the tungsten steel drill bit is connected to the punching machine through the drill rod of the fixing portion 1, and then the punching machine drives the fixing portion 1 and the cutting portion 2 for drilling to rotate, so that punching is performed on a specified position.

As shown in fig. 2 and 3, the positioning part 3 is in a ridge shape, the positioning part 3 and the blade end 41 are integrally formed, a tangent plane 31 is arranged on the positioning part 3, and the tangent plane 31 extends from the top to the cutting part 2; center through the position of waiting to punch is aimed at through the top that will be ridge form location portion 3, when punch control fixed part 1 and the cutting part 2 that is used for holing rotate the during operation, the center of the position of punching is bored earlier into through tangent plane 31 to location portion 3 that moves 2 tip of cutting part, then cutting part 2 can punch in getting into the position through cutting edge 4, prevent that the hole from beating partially, make and only adopt the drill bit, just can realize the function that the location was punched, and the work efficiency is promoted.

Example two:

as shown in fig. 1, on the basis of the first embodiment, the utility model provides a technical solution: the surface of the cutting part 2 is provided with a cutting edge 4, the end part of the cutting edge 4 far away from the fixing part 1 is a cutting edge end 41, and the cutting edge end 41 is a smooth plane; the cutting edge 4 is arranged on the surface of the cutting part 2 to punch in the part to be punched, and the edge end 41 is a smooth plane, so that the strength of the drill bit is enhanced, the stress area of the head of the drill bit is large, the pressure is small, and the service life of the drill bit is prolonged.

As shown in fig. 1 and 3, in the present embodiment, the cutting portion 2 has at least one cutting edge 4, each cutting edge 4 on the cutting portion 2 has the same structure, the cutting portion 2 has two cutting edges 4, the cutting edges 4 are distributed on the cutting portion 2 in a staggered manner, and the drill can be made of tungsten steel; the plurality of cutting edges 4 are distributed in a staggered mode, so that the drilling effect of the drill bit is enhanced.
