Description
Technical field
The present invention relates to a kind of field of drill, be related specifically to a kind of high-speed steel step drill.
Background technology
Step drill has another name called step drill or high speed steel fully ground step drill, in automobile processing, Aero-Space, panel beating, electric mounting maintenance etc.
Industry, has a lot of metal sheets to need punching, a drill bit to can substitute for branched drill bit and use, and processing is different straight as required
The hole in footpath, and macropore can be realized disposably machine, it is not necessary to more bit change and beat and position hole etc..
Owing to drill bit can produce certain heat when boring, boring can be impacted, affect work quality and work
Making efficiency, meanwhile, what the stress of step drill was maximum is the drill bit of step drill, easily causes damage, and step drill on the market is boring
Head will change whole brill while damaging, and cause waste to increase production cost, therefore need in society a kind of can solve more than
The step drill of problem.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes a kind of high-speed steel step drill.
The technical problem to be solved in the present invention is achieved through the following technical solutions.
A kind of high-speed steel step drill, including drillstock and the drill body that is arranged on drillstock portion integral molding, bottom drill body
It is provided with drill bit, is characterized in: described drillstock and drill body and drill bit coaxial line, be provided with inside drillstock and extend to bottom drill body
Aqua storage tank, be provided with several cutting portions being ladder-like arranged on drill body surface along axis, be additionally provided with spiral on drill body surface
Chip area, is provided with the groove of female thread bottom drill body, and described drill bit is movably connected on drill body, and this drill bit includes cutting
Sword and spiral chip dividing groove, be provided with and the projection of drill body groove match at drill bit top, described projection be provided with in groove
The external screw thread that screw thread matches.
One high-speed steel step drill of the present invention, further preferred technical scheme feature is:
1, described drillstock is six side's band locating slot handles；
2, the structure of described drill body is cone, and this cone basal diameter is 6cm, a height of 8cm, described conical structure
Drill body surface be hierarchic structure, diameter is gradually increased to drill body top ends top successively by drill body bottom, two adjacent diameters
Reduction scope be 0.2mm；
3, described step drill is the high-speed steel material that CBN complete wear manufactures；
4, the width of described aqua storage tank is 1.2mm.
Compared with prior art, the present invention is provided with aqua storage tank, can effectively dispel the heat, prevent when step drill works the most tropical
Carrying out unnecessary trouble, drill bit is movably connected on drill body and can be replaced drill bit simultaneously, reduces waste, owing to drill bit is lost
Greatly, drill bit can continue not utilize with outer portion, and step drill is the high-speed steel material that CBN complete wear manufactures, and the big utilization rate of hardness is high,
Several cutting portions simultaneously, being additionally provided with helical flute on drill body is in time scrap to be discharged in terms of cutting.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Referring to the drawings 1, further describe the concrete technical scheme of the present invention, in order to those skilled in the art enters
One step ground understands the present invention, and does not constitute the restriction of its power.
Embodiment 1, with reference to Fig. 1, a kind of high-speed steel step drill, including drillstock 2 and be arranged on drillstock 2 portion integral molding
Drill body 3, bottom drill body 3, be provided with drill bit 4, be characterized in: described drillstock 2 and drill body 3 and drill bit 4 coaxial line, boring
Handle 3 is internal is provided with the aqua storage tank 1 extended to bottom drill body, is provided with several that be ladder-like arranged on drill body surface along axis and cuts
Cutting portion 5, be additionally provided with helical flute 6 on drill body surface, be provided with the groove of female thread bottom drill body, described drill bit 4 is lived
Being automatically connected on drill body, this drill bit includes cutting edge and spiral chip dividing groove, is provided with at drill bit 4 top and drill body 3 groove phase
The projection joined, described projection is provided with the external screw thread matched with groove female thread.
Embodiment 2, in a kind of high-speed steel step drill described in embodiment 1: described drillstock 3 is six side's band locating slot handles.
Embodiment 3, in a kind of high-speed steel step drill described in embodiment 1: the structure of described drill body 3 is cone, this circle
The a diameter of 6cm of facies basialis pyramidis, a height of 8cm, the drill body surface of described conical structure is hierarchic structure, and diameter is by drill body 3 end
End is gradually increased successively to drill body top ends top, and the reduction scope of two adjacent diameters is 0.2mm.
Embodiment 4, in a kind of high-speed steel step drill described in embodiment 1: described step drill is the high speed that CBN complete wear manufactures
Steel matter.
Embodiment 5, in a kind of high-speed steel step drill described in embodiment 1: the width of described aqua storage tank 1 is 1.2mm.
It is last that it is noted that obviously above-described embodiment is only for clearly demonstrating example of the present invention, and also
The non-restriction to embodiment.For those of ordinary skill in the field, can also do on the basis of the above description
Go out change or the variation of other multi-form.Here without also cannot all of embodiment be given exhaustive.And thus drawn
What Shen went out obviously changes or changes among still in protection scope of the present invention.
