Abstract
A novel drilling head belongs to drilling head for metal cutting machining. The drilling head body of the drilling head is a hollow cylinder body, and the front end periphery of the hollow cylinder body is connected with a blade (1); the cylinder wall of the hollow cylinder body is provided with a chip discharge groove (3) capable of rotating along the cylinder body, a drilling tail (4) is a fixedcylinder body, is a conical handle or a straight handle. The drilling head not only can drill hole on a metal object, but also can keep the material of drilled hole during hole drilling of the metalobject, more than 90% of the drilled hole part is kept completely, the kept part has the same material as the parent body and can be used as a metal rod; the cutting area is an annular area, comparedwith prior art, the drilling head has small cutting area, small energy consumption and high drilling efficiency; the novel drilling head overcomes the defect that the drilling head in prior art has the drilling mode of making metal drilled part into chips. The novel drilling head has the advantages that: the novel drilling head can keep the material in the drilled hole during hole drilling process, improves the utilization rate of material, has high hole drilling efficiency, low energy consumption and saves great resources for society.
Description
Technical field
The utility model relates to the drill bit that uses in the processing of a kind of metal cutting machinery, particularly a kind of new drill.
Background technology
Bore mode is to adopt drill bit that the drilled part of object is become chip in the metal current cutting machine processing, and getting out the chip part can only be as waste material, thereby has caused the waste of metal material, and is particularly especially obvious to the boring processing in some large diameter holes.The existing bore mode area of cut is whole circular hole area simultaneously, and power consumption is big, and drilling efficiency is lower.
The utility model content
The purpose of this utility model is to provide a kind of: save metal material, power consumption is little, a kind of new drill that drilling efficiency is high.
The purpose of this utility model is achieved in that the bit body of this drill bit is hollow cylindrical shell, and hollow barrel front end periphery is connected with blade; Boring tail (4) is fixed cylinder, is taper shank or staight shank.
Have on the barrel of described hollow cylindrical shell along the chip area (3) of cylindrical shell rotation.
The cutting edge outer most edge diameter of living in (D1) on inclined-plane, the described blade outside is greater than the external diameter (D) of drill bit cylindrical shell, the inner edge diameter of living in (d1) of the cutting edge on the inboard inclined-plane of blade is less than the internal diameter (d) of drill bit cylindrical shell end, and blade is fixedly connected with bit body mechanically.
Beneficial effect: owing to adopted such scheme, this drill bit can not only be holed on metal object, and keep material in the drilled hole can on metal object, hole the time, the about part more than 90% of drilled hole portion is intactly remained, its material of the part that remains is the same with parent, can be used as metal bar and uses; The area of cut is an annulus area, and original relatively this bit bore of mode area of cut is little, and it is little to consume energy, the drilling efficiency height; Overcome existing drill bit the drilled part of metal is become the deficiency of the bore mode of chip, saved metal material, power consumption is little, the drilling efficiency height has reached the purpose of this utility model.
Advantage: this new drill can keep material in the drilled hole in processing boring, improves the utilization rate of material, and drilling efficiency height when holing simultaneously, power consumption are little, for society has saved a large amount of resources.

The specific embodiment
Embodiment 1: the bit body of this drill bit is hollow cylindrical shell 2, and hollow barrel front end periphery is connected with blade 1; Boring tail 4 is fixed cylinder, is taper shank or staight shank.
Have on the barrel of described hollow cylindrical shell along the chip area 4 of cylindrical shell rotation.
The cutting edge outer most edge diameter D1 of living on inclined-plane, the described blade outside is greater than the outer diameter D of drill bit cylindrical shell, and the inner edge diameter d 1 of living in of the cutting edge on the inboard inclined-plane of blade is less than the inner diameter d of drill bit cylindrical shell end, and blade is fixedly connected with bit body mechanically.
This new drill is just as a milling cutter, itself is around the axis rotation, different is along the axis direction feeding, smear metal is flowed out along flute, area of cut during boring is an annulus area, constantly forms new finished surface at the annular end of work, and is saturating up to boring, drilling efficiency and quality all are much improved, and drilled hole portion core material keeps from drill bit cylindrical shell endoporus.
Claims (3)
1, a kind of new drill is characterized in that: the bit body of this drill bit is hollow cylindrical shell, and hollow barrel front end periphery is connected with blade; Boring tail (4) is fixed cylinder, is taper shank or staight shank.
2, a kind of new drill according to claim 1 is characterized in that: have on the barrel of described hollow cylindrical shell along the chip area (3) of cylindrical shell rotation.
3, a kind of new drill according to claim 1, it is characterized in that: the cutting edge outer most edge diameter of living in (D1) on inclined-plane, the described blade outside is greater than the external diameter (D) of drill bit cylindrical shell, the inner edge diameter of living in (d1) of the cutting edge on the inboard inclined-plane of blade is less than the internal diameter (d) of drill bit cylindrical shell end, and blade is fixedly connected with bit body mechanically.
