Description
Technical field
The utility model relates to a kind of milling cutter, especially a kind of end sword cutter block.
Background technique
Mobile phone component needs groove milling and chamfering, and common mode is processed using two milling cutters, usually first with one
Milling cutter processes slot, uses another chamfering for milling cutter being processed trough rim edge after allowing again, and aforesaid way needs tool changing, not only processes
Time length, low efficiency, and processing cost is high.Thus the applicant devises a end sword cutter block to solve above-mentioned ask
Topic.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of end sword cutter block.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of end sword cutter block, including knife bar, it is characterised in that: the end of knife bar, which is equipped with, inserts milling chip space, inserts milling
Cutting portion, chamfering chip space, chamfer cutting portion, the slotting milling chip space are constituted by inserting milling straight wall face and inserting milling arc wall surface intersection；
The chamfer cutting portion is made of chamfering straight wall face and the intersection of chamfering arc wall surface, and milling is inserted by first in the end face of the slotting milling cutting portion
Flank and second insert milling flank constitute, and first insert milling flank and insert milling straight wall face intersection constitute insert milling sword；It is described fall
The end face of angle cutting portion is made of the first chamfering flank and the second chamfering flank, and the first chamfering flank and chamfering straight wall
Face intersection constitutes chamfering blades.
The first chamfering flank is made of preceding first chamfering flank and rear first chamfering flank；Described second falls
Angle flank is made of preceding second chamfering flank and rear second chamfering flank, the preceding first chamfering flank and it is described fall
Chamfering blades before the intersection of angle straight wall face is constituted, the rear first chamfering flank intersect chamfering after composition with chamfering straight wall face
Sword, the angle that the preceding chamfering blades intersect with rear chamfering blades and the two is crossed to form be obtuse angle, the chamfering blades by preceding chamfering blades with
Chamfering blades are constituted afterwards.
The end of the knife bar is equipped with several evacuation inclined-planes.
The beneficial effects of the utility model are: the end of the knife bar of the utility model is equipped with slotting milling chip space, slotting milling is cut
Portion, chamfering chip space, chamfer cutting portion, the slotting milling chip space are constituted by inserting milling straight wall face and inserting milling arc wall surface intersection；It is described
Chamfer cutting portion is made of chamfering straight wall face and the intersection of chamfering arc wall surface, and the end face of the slotting milling cutting portion is by knife after the first slotting milling
Face and second insert milling flank constitute, and first insert milling flank and insert milling straight wall face intersection constitute insert milling sword；The chamfering is cut
The end face for cutting portion is made of the first chamfering flank and the second chamfering flank, and the first chamfering flank and chamfering straight wall face phase
Hand over constitute chamfering blades, by above structure, this milling cutter with slotting milling cutting portion processing groove while, can by with slotting milling
The edge of groove is processed into chamfering by the chamfer cutting portion that the portion of cutting is set side by side, and above-mentioned operation is once completed, not only process time
Short, high-efficient and structure is simple, to reduce processing cost.
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；
Fig. 2 is the three-dimensional view of the utility model；
Fig. 3 is the amplification three-dimensional view of the knife bar end of the utility model.
Specific embodiment
Referring to figs. 1 to Fig. 3, the utility model discloses a kind of end sword cutter block, including knife bar 1, the ends of knife bar 1
Equipped with slotting milling chip space, milling cutting portion 3, chamfering chip space, chamfer cutting portion 5 are inserted, the slotting milling chip space is by inserting milling straight wall face
(not showing in figure) and insert milling arc wall surface (not showing in figure) intersection composition；The chamfer cutting portion 5 is by chamfering straight wall face 2
And the intersection of chamfering arc wall surface 4 is constituted, arc wall surface can guide chip removal, and straight wall face solid capacity is big, thus insert milling chip space and chamfering
The structure of chip space is conducive to chip removal, and the end face of the slotting milling cutting portion 3 is by knife after the first slotting milling flank 6 and the second slotting milling
Face 7 constitute, and first insert milling flank 6 and insert milling straight wall face intersection constitute insert milling sword 8；The end face in the chamfer cutting portion 5 by
First chamfering flank and the second chamfering flank are constituted, and the first chamfering flank and the intersection of chamfering straight wall face 2 constitute chamfering
Sword.
As shown, the first chamfering flank is by preceding first chamfering flank 9 and rear first chamfering flank, 10 structure
At；The second chamfering flank is made of preceding second chamfering flank 11 and front and back the second chamfering flank 12, and described preceding
One chamfering flank 9 intersect with chamfering straight wall face 2 composition before chamfering blades 13, it is described after the first chamfering flank 10 with it is described
Chamfering blades 14 after the intersection of chamfering straight wall face 2 is constituted, the preceding chamfering blades 13 intersect with rear chamfering blades 14 and the two is crossed to form
Angle is obtuse angle, and the chamfering blades are made of preceding chamfering blades 13 and rear chamfering blades 14, and by above structure, we are when chamfering
Tool can be poured out, and there are two the chamferings of intersection folding surface.
As shown, the end of knife bar 1 is equipped with several evacuation inclined-planes 15, such work in-process is convenient for avoiding the end of knife bar 1
Portion and workpiece are interfered.
It above to a kind of end sword cutter block provided by the utility model embodiment, is described in detail, herein
