Description
Technical field
This utility model relates to metal-cutting machine tool technical field, and the high strength hard particularly relating to a kind of band chip-breaker closes
Gold milling cutter.
Background technology
Milling cutter is for Milling Process, has the rotary cutter of one or more cutter tooth.During work, each cutter tooth can be successively
Interval remove cut part, milling cutter is mainly used in processing step on milling machine, plane, groove, molded surface and cut-out workpiece etc..
Carbide-tipped milling cutter is mainly used in rough milling, big for large-scale alloy forged piece roughing machining amount.By
Being difficult to that cutter head is carried out cooling in the usual type of cooling makes cutting speed can not improve all the time, have impact on working (machining) efficiency；With
Time cut off chip time, chip easily produces the chip band being wound in web-like, and the chip band of web-like is difficult to be cut off so that it is cannot
Effectively come off, improve cutting opposing, thus machined surface precision cannot be kept, reduce the use longevity of carbide-tipped milling cutter
Life.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the high-strength rigid of a kind of band chip-breaker
Matter alloy milling cutter.
This utility model is to be achieved through the following technical solutions:
The high strength cemented carbide milling cutter of a kind of band chip-breaker, including knife bar and end mill body, one end of described knife bar and institute
The one end stating end mill body links together, and is provided with milling cutter tooth, and is machined with spiral helicine chip area on described end mill body,
It is machined with chip-breaker on the milling cutter tooth of described end mill body；And offer helical form liquid stream through hole inside described knife bar, and in institute
The one end stating helical form liquid stream through hole is machined with cylindrical flow through hole, and described cylindrical flow through hole extends to end mill body
End.
As optimal technical scheme of the present utility model, one end of described knife bar is machined with chamfering, and described helical form liquid
The inlet of opening communicates with the end face of chamfering.
As optimal technical scheme of the present utility model, the degree of depth of described chip-breaker is 1mm-2mm, the width of described chip-breaker
Degree is 1mm-2mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design,
Easy to operate, it is provided by chip-breaker, it is possible to effectively cut off chip band, makes chip will not produce winding, it is simple to control to cut
The outflow direction of bits, thus ensure machined surface precision, reduce cutting opposing, extend cutter life；It is provided by helical form liquid
Opening and cylindrical flow through hole, be effectively reduced temperature during end mill body corase grind, and coolant flows to outside end mill body
Also can continue as end mill body outer surface and cooling effect is provided.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
The high strength cemented carbide milling cutter of described a kind of band chip-breaker, including knife bar 1 and end mill body 2, the one of described knife bar 1
Hold the one end with described end mill body 2 to link together, described end mill body 2 is provided with milling cutter tooth 21, and is machined with helical form
Chip area 22, the milling cutter tooth 21 of described end mill body 2 is machined with chip-breaker 23；And offer spiral shell inside described knife bar 1
Rotation shape liquid stream through hole 11, and it is machined with cylindrical flow through hole 12, and described circle in one end of described helical form liquid stream through hole 11
Cylindricality liquid stream through hole 12 extends to the end of end mill body 2.
One end of described knife bar 1 is machined with chamfering 13, and the inlet of described helical form liquid stream through hole 11 and chamfering 13
End face communicates.
The degree of depth of described chip-breaker 23 is 1mm-2mm, and the width of described chip-breaker 23 is 1mm-2mm.
It is provided by chip-breaker, it is possible to effectively cut off chip band, makes chip will not produce winding, it is simple to control chip
Outflow direction, thus ensure machined surface precision, reduce cutting opposing, extend cutter life.
Being provided by helical form liquid stream through hole and cylindrical flow through hole, coolant first passes through helical form liquid stream through hole,
Subsequently into cylindrical flow through hole, finally flowing out, the coolant of outflow acts on end mill body outer surface, continues as milling cutter and dissipates
Heat, plays cooling effect to milling cutter, is effectively reduced temperature during end mill body corase grind, and coolant flows to outside end mill body also
End mill body outer surface can be continued as cooling effect is provided.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
