Description
Technical field
The present invention relates to metal cutting tool technical fields, expand chamfering one fried dough twist particularly for the brill of taper hole machined
It bores.
Background technology
The processing of traditional tapered hole is that subdrilling bottom outlet carries out taper reaming using cornish bit again, finally using rose reamer interpolation
Milling orifice chamfer, the tool magazine warehouse compartment that this traditional processing method does not only take up is more, and processing efficiency is low, of high cost, can not
Meet the requirement of modern industry highly-efficient processing.
For the taper hole machined of plastic material, compared by plastic material self character and the taper cornish bit conical surface (sword)
Long influence, it cuts flaky without easy chip breaking when carrying out taper hole machined using above-mentioned conventional method, so as to be formed
Long coil chip, and then lathe is caused to load larger, cutter and blocks, burn out the failures such as motor.
To solve the above-mentioned problems, occur a kind of brill that drill bit and taper cornish bit are combined into one in the art to expand
Integrated drill bit, is shown in Fig. 1, and bit part A and taper reaming part C is linked into an integrated entity by the way that neck portion B is concentric, but due to adding
Equipped with neck so as to lengthen an overall length for entire cutter, the rigidity for resulting in cutter is deteriorated, therefore can be only applied to such as aluminium alloy
This rigid requirements of material are not very high occasions, and can not be applied to the taper hole machined of the higher rigid components of rigid requirements
In, the scope of application is small；Simultaneously because there is provided necks, neck is still located in drilling after bit part has drilled through part,
Therefore secondary centering is needed when taper reamer is cut into drilling, this can not only increase cutter load but also inevitably occur
The deviation of secondary positioning centering, influences machining accuracy afterwards.
Invention content
In view of the above-mentioned problems, the present invention provides chamfering one fluted drill is expanded for the brill of taper hole machined, it can not only
It solves the problems, such as that efficiency existing for traditional taper hole machined is low, of high cost, while existing bore can also be solved and expand integrated drill bit because just
Property difference and the problem of be not suitable for plastic material taper hole machined.
Its technical solution is to expand chamfering one fluted drill for the brill of taper hole machined, include the drill body of concentric one
Part and shank body part, the shank body part are a cylinder, and the drill body part is ladder circle cylinder, the drill body part packet
Drilling portion and taper reamer are included, the taper reamer periphery offers chip space and the chip space is in the taper reaming
Portion periphery forms knife spine, it is characterised in that：It is connected as a single entity between the drilling portion and taper reamer by the way that even mill mode is concentric,
The taper reamer and the junction of shank body part are equipped with chamfered section.
Further, several forced chip-cutting slots are provided in the axial direction on the peripheral surface of the taper reamer.
Further, the forced chip-cutting slot is V-shaped.
Further, the both sides groove face of the V-shaped forced chip-cutting slot is connected in slot bottom position in R shapes arc transition.
Further, it is in 90 degree of angles between the both sides groove face of the V-shaped forced chip-cutting slot.
The beneficial effects of the present invention are：Between its drilling portion and taper reamer one is linked as by the way that even mill mode is concentric
On the one hand body effectively reduces entire cutter length, improves cutter rigidity, and reconditioning can be carried out after cutter use, not only
Tool life and processing, being applied widely for the steel class part higher to rigid requirements can be can be applied to；
On the other hand it is connected as a single entity due to directly concentric between drilling portion and taper reamer, thus while drilling portion drills through part
Taper reamer has cut drilling, so as to effectively prevent secondary positioning centering during taper reamer reaming, therefore can effectively carry
The machining accuracy of high taper hole；Chamfered section is set between taper reamer and shank body part simultaneously, thus single feeding can be real
Now drilling, the disposable processing of three processing steps of taper reaming and orifice chamfer, therefore processing efficiency can be greatly improved, reduced
The cost of charp tool reduces production cost on the whole；In addition, when the integrated fluted drill of the present invention is applied to the cone hole machine of plastic material
When, several forced chip-cutting slots can long paper bits force disconnect of flaky caused by cutting to taper reamer, so as to ensure
Chip can be discharged smoothly；And force chip space in 90 degree V-arrangement angle and slot bottom be R shape arc transitions, can effectively prevent
Only stress concentration so that long paper bits are more easy to cut off and are more easy to discharge.
To sum up, the present invention expands chamfering one fluted drill for the brill of taper hole machined, by drilling portion and taper reamer
Directly in conjunction with integral by way of even grinding, so as to effectively improve cutter rigidity, tool life, and taper expands
Chamfered section is provided between hole portion and shank body part so that the present invention can disposably complete drilling, taper reaming and aperture
The molding of chamfering can greatly improve processing efficiency；The forced chip-cutting slot that is set by taper reamer is effectively improved simultaneously
Chip breaking switch when reaming is processed, so as to thoroughly solve from aluminium alloy to steel part or even the toughness material of low nickel stainless steel class
The cone hole machine of material effectively increases the scope of application of cutter, further reduces the cost of charp tool.
