Abstract
A kind of hemi-spherical ended shape insert blast furnace opening drill bit disclosed by the invention, including drill body, side sword is provided on the drill body, one end junction of all side swords forms sharp sword together, the other end of the side sword extends outwardly, and the side sword extending direction is 30 °~60 ° relative to the inclination angle of drill body axial direction.Using technical solution of the present invention, good positioning can be realized by sharp sword when in use, avoid having skidded in drilling operation, bore inclined phenomenon, by inlaying hemi-spherical ended shape insert in side sword two sides, hemi-spherical ended shape insert increases impact force when drill bit drilling, repeated stock can be formed to the blast furnace gun after hardening and improve drilling efficiency so that drill bit be made to be easy to creep into, shorten drilling time, in addition, the addition of hemi-spherical ended shape insert decreases the abrasion of opposite side sword, the service life of drill bit is extended.
Description
Technical field
The invention belongs to blast furnace maintenance tool technical fields, are related to a kind of hemi-spherical ended shape insert blast furnace opening drill bit.
Background technique
The blast furnace of smelting iron and steel needs to be drilled the clay gun on blast furnace with drill bit, and molten iron is released.In the prior art, due to
The drilling rod for connecting drill bit is longer, and drill bit is easy to skid on clay gun, bore partially, reduces the efficiency of drilling, the hole drilled out is not yet
Enough rules, influence the quality of tapping, in addition, since blast furnace gun is in higher, the existing opening by heat setting hardness later
Drill bit rate of penetration is slow and low efficiency, and service life is short, therefore, in order to overcome defect existing in the prior art, there is an urgent need to
Design and develop a kind of novel blast furnace opening drill bit.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of hemi-spherical ended shape insert blast furnace opening drill bits.
The present invention is achieved by the following technical programs.
A kind of hemi-spherical ended shape insert blast furnace opening drill bit provided by the invention, including drill body are arranged on the drill body
There is Bian Ren, one end junction of all side swords forms sharp sword together, and the other end of the side sword extends outwardly, and the side sword extends
Direction is 30 °~60 ° relative to the inclination angle of drill body axial direction.
The side sword quantity is 3 or more.
The hemi-spherical ended shape insert blast furnace opening drill bit further includes more hemi-spherical ended shape inserts, and side sword two sides are provided with inclined sword slope
Face, the part inlay of hemi-spherical ended shape insert is on sword slope surface.
The material of the hemi-spherical ended shape insert is hard alloy.
Hemi-spherical ended shape insert quantity, which is inlayed, on the sword slope surface is no less than 2.
The hemi-spherical ended shape insert is embedded in half that the part within sword slope surface is the hemi-spherical ended shape insert volume to 2/3rds.
The hemi-spherical ended shape insert outer diameter is the one third of the sword slope surface width to half.
It is additionally provided with connection blind hole within the drill body, at least one chip removal is provided between adjacent two edges sword
Hole, chip-removal hole are connected to blind hole is connect.
The connection blind hole inner wall is provided with screw thread.
The beneficial effects of the present invention are: technical solution of the present invention is used, can be realized when in use by sharp sword good
Good positioning, avoids that inclined phenomenon is had skidded, bored in drilling operation, by inlaying hemi-spherical ended shape insert in side sword two sides, hemi-spherical ended shape insert
Impact force when drill bit drilling is increased, repeated stock can be formed to the blast furnace gun after hardening, so that drill bit be made to be easy to bore
Into improving drilling efficiency, shorten drilling time, in addition, the addition of hemi-spherical ended shape insert decreases the abrasion of opposite side sword, extend
The service life of drill bit.
Detailed description of the invention
Fig. 1 is top view of the invention；
Fig. 2 is cross-sectional view of the present invention along drill body axial direction cutting.
In figure: 1- drill body, the side 2- sword, 3- point sword, 4- hemi-spherical ended shape insert, 5- sword slope surface, 6- connection blind hole, 7- chip-removal hole.
Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1 and Figure 2, a kind of hemi-spherical ended shape insert blast furnace opening drill bit of the invention, including drill body 1, drill body 1
On be provided with side sword 2, one end junction of all side swords 2 forms sharp sword 3 together, and the other end of Bian Ren 2 extends outwardly, Bian Ren
The 2 extending directions inclination angle axial relative to drill body 1 is 30 °~60 °.
It is preferred that sword 2 quantity in side is 3 or more.In addition, hemi-spherical ended shape insert blast furnace opening drill bit further includes more hemi-spherical ended shape inserts 4, Bian Ren 2
Two sides are provided with inclined sword slope surface 5, and the part inlay of hemi-spherical ended shape insert 4 is on sword slope surface 5.It is preferred that the material of hemi-spherical ended shape insert 4 is hard
Matter alloy.4 quantity of hemi-spherical ended shape insert is inlayed on sword slope surface 5 is no less than 2.It is ball that hemi-spherical ended shape insert 4, which is embedded in the part within sword slope surface 5,
The half of 4 volume of shape tooth is to 2/3rds.4 outer diameter of hemi-spherical ended shape insert is the one third of 5 width of sword slope surface to half.
In addition, being additionally provided with connection blind hole 6 within drill body 1, at least one row is provided between adjacent two edges sword 2
Consider hole 7 to be worth doing, chip-removal hole 7 is connected to blind hole 6 is connect.Using technical solution of the present invention, drill bit when in use can by chip-removal hole 7 what
It connects blind hole 6 and carries out deslagging.
Further, connection 6 inner wall of blind hole is provided with screw thread.User can also be connected the present invention by connection blind hole 6
It is carried out on corresponding drilling tool using compared with prior art, drill bit and drilling tool capable of being made to connect by the connection type of screw thread pair
It connects more firm and reliable.
Using technical solution of the present invention, good positioning can be realized by sharp sword when in use, avoid grasping in drilling
As when have skidded, bore inclined phenomenon, by inlaying hemi-spherical ended shape insert in side sword two sides, hemi-spherical ended shape insert increases impact when drill bit drilling
Power can form repeated stock to the blast furnace gun after hardening and improve drilling efficiency so that drill bit be made to be easy to creep into, shorten
Drilling time in addition, the addition of hemi-spherical ended shape insert decreases the abrasion of opposite side sword extends the service life of drill bit.
