Abstract
The utility model discloses the left-handed left cut rose reamers of processing alloy steel spring piece endoporus, the drilling rod that cutter head is equipped with by both ends is constituted, the cutter head forms two chip spaces by processing of putting the first edge on a knife or a pair of scissors, and two chamfering blades are constituted between two chip spaces, the chamfering blades are set in the chamfering of cutter head, and the end of chamfering is all made of pointed design and forms apex point, compared with prior art, the advantageous effect of the left-handed left cut rose reamer of processing alloy steel spring piece endoporus provided by the utility model is this kind of reversed cutter collection dot center, chamfering, two-way processing is multi-functional in one, pass through the design method of the same two-way cutting edge of branch cutter, both cutter life is improved, the cost of charp tool has been saved again.
Description
Technical field
The utility model is related to a kind of chamfering blades, specially process the left-handed left cut rose reamer of alloy steel spring piece endoporus.
Background technology
Rose reamer be assemblied on the lathes such as milling machine, drilling machine, planer, beveler for 60 degree 90 degree of workpieces processing and
120 degree of chamferings belong to slotting cutter with taper hole, reverse mould corner angle cutter.Rose reamer is also chamfering device.The rose reamer scope of application
Extensively, it is not only suitable for the chamfering of standard machinery workpiece, chamfering and the deburring of angle workpiece are baffled more suitable for precision.Such as：Boat
Sky, military project, auto industry oil, gas, motor-driven valve, engine cylinder body, cylinder, sphere through-hole, inner wall hole.
Now providing a kind of reversed cutter, to integrate dot center, chamfering, two-way processing multi-functional, and it is double to pass through same branch cutter
To the design method of cutting edge, cutter life is not only improved, but also saved the cost of charp tool.
Utility model content
To solve the problems mentioned above in the background art, the purpose of this utility model is to provide processing alloy steel springs
The left-handed left cut rose reamer of piece endoporus not only improves cutter life, but also section by the design method of the same two-way cutting edge of branch cutter
The about cost of charp tool.
The purpose of this utility model is achieved by following technical proposals:Process the left-handed of alloy steel spring piece endoporus
Left cut rose reamer, the drilling rod that cutter head is equipped with by both ends are constituted, and the cutter head forms two chip spaces by processing of putting the first edge on a knife or a pair of scissors, and two
Two chamfering blades are constituted between chip space, the chamfering blades are set on the fillet surface of cutter head, and the end of fillet surface is all made of point
It designs and forms apex point in angle.
Further, the use whole hard alloy of the drilling rod is made.
Further, the length of the drilling rod is 60mm, and the cutter head length at both ends is 12mm.
Further, the fillet surface busbar angle of the cutter head is 30 °, and the angle of apex point is 140 °.
Compared with prior art, the left-handed left cut rose reamer of processing alloy steel spring piece endoporus provided by the utility model
It is multi-functional that advantageous effect is that this kind of reversed cutter integrates dot center, chamfering, two-way processing, passes through the same two-way sword of branch cutter
The design method of mouth, not only improves cutter life, but also saved the cost of charp tool.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment is based on the embodiments of the present invention, and those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-3, the left-handed left cut rose reamer for processing alloy steel spring piece endoporus is equipped with the brill of cutter head 2 by both ends
Bar 1 is constituted, and the cutter head 2 forms two chip spaces 4 by processing of putting the first edge on a knife or a pair of scissors, and two chamfering blades 3 are constituted between two chip spaces 4,
The chamfering blades 3 are set on the fillet surface 21 of cutter head 2, and the end of fillet surface 21 is all made of pointed design and forms apex point
22。
The drilling rod 1 is made of whole hard alloy, has high tenacity and high rigidity.The length of the drilling rod 1 is
2 length of cutter head of 60mm, both ends are 12mm.The 21 busbar angle of fillet surface of the cutter head 2 is 30 °, and the angle of apex point 22 is
140°。
It is multi-functional that this kind of reversed cutter integrates dot center, chamfering, two-way processing, passes through the same two-way cutting edge of branch cutter
Design method, not only improve cutter life, but also saved the cost of charp tool.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
