Description

Tapping drill bit of ferroalloy furnace

Technical Field

The utility model relates to the technical field of auxiliary equipment for alloy production, in particular to a tapping drill bit of a ferroalloy furnace.

Background

In the casting process of alloy products, materials are required to be melted into liquid in a ferroalloy furnace, then the metal liquid in the ferroalloy furnace is cast in a mould, in order to facilitate casting, a hole is usually formed in the side wall of the ferroalloy furnace, in the process of melting metal, the hole is closed, the hole is opened only when the metal liquid is cast, but after casting is finished, the metal liquid residues are remained on the inner wall of the hole, the metal liquid is fixed on the inner wall of the hole after cooling and can block the hole after long-time use, so the inner wall of the hole can be cleaned by a drill bit after casting is finished, but the existing drill bit is only provided with a grinding head at the end part of the drill bit, so that the side wall of the hole is difficult to clean.

Disclosure of Invention

To the not enough of above-mentioned relevant prior art, this application provides an iron alloy stove trompil drill bit, can carry out the omnidirectional clearance to the lateral wall of hole, guarantees the cleaning effect, can ventilate at the in-process of clearance simultaneously, reduces the temperature when drilling, has stronger practicality.

In order to achieve the above object, the present utility model adopts the following technique:

a ferroalloy furnace tapping drill, comprising: the body and the second wear-resisting point.

The surface of one end of the body is provided with a plurality of first wear-resisting points, the other end of the body is provided with a threaded column, one end of the threaded column is provided with a ventilation main hole, the inside of the body is provided with a plurality of ventilation auxiliary holes which penetrate through the body, and the ventilation auxiliary holes are connected with the ventilation main hole; the second wear-resisting point has a plurality ofly, and the circumference side of circumference direction equipartition in the body.

Further, an inclined plane is arranged at one end edge of the body, and a plurality of second wear-resisting points are uniformly distributed on the inclined plane along the circumferential direction.

Further, the wear-resisting points are all made of high-temperature-resistant materials.

Further, the first wear-resisting point, the second wear-resisting point and the body are detachably connected.

Further, the surfaces of the parts of the first wear-resistant point and the second wear-resistant point, which are positioned outside the body, are arc-shaped.

The utility model has the beneficial effects that: through also setting up the wear-resisting point in the side of drill bit body, can carry out the omnidirectional clearance to the lateral wall of hole, guarantee the clearance effect to can ventilate in the in-process of clearance to the drill bit body, reduce the temperature when drilling, improve the practical life of drill bit.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the following detailed description of the embodiments of the present utility model will be given with reference to the accompanying drawings, but the described embodiments of the present utility model are some, but not all embodiments of the present utility model.

As shown in fig. 1-3, the present example provides a ferroalloy furnace tapping drill, comprising: a body 1 and a second wear-resistant point 2.

The surface of one end of the body 1 is provided with a plurality of first wear-resistant points 14, the other end of the body is provided with a threaded column 11, one end of the threaded column 11 is provided with a ventilation main hole 12, a plurality of through ventilation auxiliary holes 13 are formed in the body 1, the ventilation auxiliary holes 13 are connected with the ventilation main hole 12, ventilation is carried out through the ventilation main hole 12 and the ventilation auxiliary holes 13 during drilling operation, the temperature during drilling is reduced, and the service life of a drill bit is prolonged; the second wear-resisting points 2 are a plurality of and are uniformly distributed on the periphery of the body 1 along the circumferential direction.

Specifically, in order to further ensure the cleaning effect to the hole, an inclined plane is arranged at one end edge of the body 1, and a plurality of second wear-resisting points 2 are uniformly distributed on the inclined plane along the circumferential direction.

Specifically, the wear-resisting points 2 are made of high-temperature-resistant materials, so that the service life of the drill bit is prolonged.

Specifically, the first wear-resisting point 14, the second wear-resisting point 2 and the body 1 are all detachably connected, for example, the first wear-resisting point 14 or the second wear-resisting point 2 are conveniently replaced after being worn by adopting a threaded or fastening structure, and the first wear-resisting point 14 is distributed in an S shape on the surface of the body 1, so that a drill bit is more conveniently drilled in a hole.

Specifically, the surfaces of the parts of the first wear-resistant point 14 and the second wear-resistant point 2, which are positioned outside the body 1, are arc-shaped, so that the drilling in the hole of the drill bit is further facilitated.

The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model, and it is obvious that those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model.
