Description
Technical field
It drills and reams combination forming knife the utility model relates to a kind of forming cutter, especially one kind.
Background technique
Pervious component needs to process one, and there is high-precision hole process to be needed successively repeatedly to use much knives, above-mentioned
Mode needs tool changing, not only long processing time, low efficiency, but also processing cost is high.Thus the applicant devises one kind and drills and reams
Combination forming knife solves the above problems.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides one kind and drills and reams combination forming knife.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
One kind drills and reams combination forming knife, it is characterised in that: including knife bar and cutter head, the cutter head is equipped with four uniformly rows
The end of the spiral combination blade and cutter head that are distributed on cutter head is opposite to be equipped with drill lip portion, is equipped with spiral shape between two combination blade
Chip space, the combination blade include reaming section and fraising section, the reaming section include reaming rake face, reaming flank,
And the helical counterbore sword that reaming rake face and the intersection of reaming flank are constituted；The fraising section includes fraising rake face, hinge
The spiral shape fraising sword that hole flank and fraising rake face and flank intersection of reaming are constituted, the drill lip portion includes drill lip
The drilling sword that rake face, drill lip flank and drill lip rake face and the intersection of drill lip flank are constituted, the drilling sword are always
Line and at an acute angle with the central axis of cutter head, the drill lip flank intersects with corresponding reaming flank, the drilling sword with
The sword diameter of corresponding reaming sword connection, the fraising sword is greater than the sword diameter of reaming sword.
The drill lip rake face, reaming rake face and fraising rake face are that the corresponding portion of the side wall of chip space is constituted.
The shiny surface intersected respectively with above-mentioned the two is equipped between the reaming flank and fraising flank.
The diameter of the cutter head is greater than the diameter of knife bar.
The beneficial effects of the utility model are: the utility model includes knife bar and cutter head, the cutter head is equipped with four
The end of the even spiral combination blade and cutter head being arranged on cutter head is opposite to be equipped with drill lip portion, and combination blade includes reaming section
And fraising section, the drill lip portion are equipped with drilling sword and can drill in work piece surface, then pass through the reaming sword on reaming section
Continue reaming deep drilling, reams finally by the fraising sword in fraising section, hole wall is bright and clean and precision to reach.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model.
Specific embodiment
Referring to Fig.1, it drills and reams combination forming knife, including knife bar 1 and cutter head 2 the utility model discloses one kind, the cutter head 2
The end for being equipped with spiral combination blade and cutter head 2 that four are uniformly arranged on cutter head 2 is equipped with drill lip portion, drill lip relatively
Thus setting two-edged guarantees chip removal to portion's solid capacity greatly, and combine blade be in order to further by hole machined to size and precision thus
Machining allowance is small, and chip removal is small and high to hole wall finish and precision, described to want four, is equipped with spiral row between two combination blade
Consider to be worth doing slot 3, the combination blade include reaming section and ream section, the reaming section include reaming rake face, reaming flank 4, with
And the helical counterbore sword 5 that reaming rake face and the intersection of reaming flank 4 are constituted；The fraising section includes fraising rake face, hinge
The spiral shape fraising sword 7 that hole flank 6 and fraising rake face and the intersection of flank 6 of reaming are constituted, the drill lip portion includes boring
The drilling sword 9 that sword rake face, drill lip flank 8 and drill lip rake face and the intersection of drill lip flank 8 are constituted, the drilling sword 9
It is for a straight line and at an acute angle with the central axis of cutter head 2, preferably 60 degree of the angle, the drill lip flank 8 and corresponding reaming
Flank 4 intersects, and the drilling sword 9 is connected with corresponding reaming sword 5, and the sword diameter of the fraising sword 7 is greater than the sword of reaming sword 5
Diameter.
The drill lip rake face, reaming rake face and fraising rake face are that the corresponding portion of the side wall of chip space 3 is constituted.
The shiny surface 10 intersected respectively with above-mentioned the two is equipped between the reaming flank 4 and fraising flank 6, because expanding
Hole flank 4 and fraising flank 6 are difficult to accomplish to be smoothly connected, thus will appear high point and scratch hole wall, thus need two
The intersection milling of person is flat.
The diameter of the cutter head 2 is greater than the diameter of knife bar 1, is convenient for clamping in this way, is positioned by the end face of cutter head 2.
It drills and reams combination forming knife, is described in detail to one kind provided by the utility model embodiment above, herein
In apply specific case the principles of the present invention and embodiment be expounded, the explanation of above embodiments is only used
The method and its core concept of the utility model are understood in help；At the same time, for those skilled in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification is not
It is interpreted as limitations of the present invention.
