Abstract
The invention discloses a tungsten steel burr which comprises a mounting handle made of stainless steel and a cutting head fixedly connected with one end of the mounting handle, wherein a plurality of pyramidal concave holes are formed in the surface of the cutting head, the pyramidal concave holes are uniformly distributed on the surface of the cutting head, and a cutting edge is clamped between adjacent pyramidal concave holes. After the pyramidal concave holes are additionally formed in the cutting edge of the tungsten steel burr, the chip removal speed during cutting can be favorably increased, thereby increasing the working efficiency, enhancing the cutting effect and also guaranteeing the cutting quality.
Description
Technical field
The present invention relates to oral cavity grind one's teeth in sleep instrument field, be specifically related to a kind of wolfram steel car pin.
Background technology
High speed dental burs be Dentist in department of stomatology therapeutic room, make when drilling tooth
With, it is the requisite important tool of Dentist clinical treatment；Dental sewing machine needle is by syringe needle (work
Make portion) and needle handle (shank) composition.It is mouth that high speed dental burs introduces high speed dental burs
Chambered doctor, in department of stomatology therapeutic room, uses when drilling tooth, is Dentist clinical treatment
Requisite important tool；Dental sewing machine needle is by syringe needle (work portion) and needle handle (shank) group
Become.High speed dental burs in use can of short duration entrance tissue of tooth the contact blood of patient, body
Liquid, is attributed to two class medical device supervision.High speed dental burs is by steel or wolfram steel manufacture, due to steel
Hardness strength low, be difficult to processing precise sword tooth, seldom have steel high speed dental burs face
City, the mainly wolfram steel high speed dental burs of present commercial type.Car pin of the prior art
Surface indentation is less, it is easy to produced powder of being ground one's teeth in sleep blocks, and affects stock-removing efficiency.
Summary of the invention
It is an object of the invention to overcome defect present in prior art, it is provided that a kind of wolfram steel car
Pin, chip removal speed is fast, improves stock-removing efficiency.
For achieving the above object, the technical scheme is that a kind of wolfram steel car pin of design, including
The installing handle being made of stainless steel fixes, with described installing handle one end, the bit being connected, and it is special
Levying and be, described bit surface configuration has several pyramid type shrinkage pools, described pyramid type shrinkage pool
It is uniformly distributed on described bit surface, described cutting edge is folded in adjacent described pyramid type
Between shrinkage pool.
As preferably, described pyramid type shrinkage pool is rectangular pyramid shape, and described pyramid type shrinkage pool is being cut
The opening cutting head surface is rhombus.
As preferably, the outline of described bit is spindle, taper type or taper.
Advantages of the present invention and having the beneficial effects that: increase pyramid on the cutting edge of wolfram steel car pin
After type shrinkage pool, it is favorably improved chip removal speed during cutting, thus improves work efficiency, increase
Strong cutting effect, also ensure that cutting quality simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention；
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
In figure: 1, installing handle；2, bit；3, cutting edge；4, pyramid type shrinkage pool.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is retouched further
State.Following example are only used for clearly illustrating technical scheme, and can not be with
This limits the scope of the invention.
As depicted in figs. 1 and 2, wolfram steel car pin include the installing handle 1 that is made of stainless steel and
The bit 2 of connection is fixed in installing handle 1 one end, and bit 2 surface configuration has several pyramids
Type shrinkage pool 4, pyramid type shrinkage pool 4 is uniformly distributed on bit 2 surface, and cutting edge 3 is folded in
Between adjacent pyramid type shrinkage pool 4.
In the present embodiment, pyramid type shrinkage pool 4 is rectangular pyramid shape, and pyramid type shrinkage pool 4 is in bit
The opening on surface is rhombus；The outline of bit 2 is taper type.
The outline of bit can also be spindle, taper, by controlling pyramid type shrinkage pool
The degree of depth ensures suitable chip removal speed, further, it is also possible to by controlling adjacent pyramid type shrinkage pool
Between cutting edge width control cutting speed.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
Making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
