Description
Technical field
The utility model belongs to wire pulling method technical field, more particularly to a kind of broaching cutters.
Background technique
Broaching has a long history as a kind of machining mode, either cutter material or broaching cutters knot
Structure etc. is all had large improvement, but still uses high speed steel material with entirety or have based on welded cutter, mill
Reconditioning is needed after damage, at high cost, low efficiency, when especially for difficult-to-machine materials such as turbine disk blade root slots, existing cutter can not expire
The needs of sufficient wire pulling method.
Summary of the invention
In view of the deficiency of the prior art, the utility model provides a kind of simple structure and reasonable design, application
Good, the at low cost indexable broaching tool of energy.
Technical solution adopted in the utility model is: indexable broaching tool, including broaching tool cutter hub, multiple blades and multiple solid
Determine screw；Broaching tool cutter hub top is equipped with multiple insert grooves, and the multiple insert groove is arranged along broaching tool cutter hub length direction, often
A blade is equipped in a insert groove, each blade lower end contradicts on corresponding insert groove, and each blade passes through
Fixing screws are fixedly connected with broaching tool cutter hub, and position of the multiple insert groove on broaching tool cutter hub successively increases, the multiple
Blade is rectangular knife, and the four edges of each blade are equipped with cutting edge, and each cutting edge has cutting anterior angle.
The utility model has the beneficial effects that:
1, the utility model within the scope of one fixed width, fix by broaching tool cutter hub width, real by gradually rising for insert groove
The variation of existing broaching tool broaching depth.
2, the utility model is designed reasonably, structure is simple, and adjustment is flexible and convenient, can mass production, and when blade damages
Bad when, need to only be replaced, and cutter does not need reconditioning, further reduced cutter cost of use, and the utility model is used for
Medium or severe type cutting, is a kind of high speed broaching cutters.
3, the utility model reasonably designs its structure and cutting angle, reasonably by CAD mode
The technique for working out each part, is processed using high precision machine tool, guarantees the precision and quality of part.Broaching tool installation, easy to adjust, knife
Piece indexing is flexibly, high in machining efficiency.
Detailed description of the invention
Fig. 1: the utility model main view；
Fig. 2: the utility model left view；
Fig. 3: the utility model blade left view；
Wherein: 1- broaching tool cutter hub；1-1- insert groove；2- blade；2-1- cutting edge；3- fixing screws.
Specific embodiment
As shown in Fig. 1 ~ Fig. 3, indexable broaching tool, including broaching tool cutter hub 1, multiple blades 2 and multiple fixing screws 3；It is described
1 top of broaching tool cutter hub is equipped with multiple insert groove 1-1, and the multiple 2 slot of blade is arranged along 1 length direction of broaching tool cutter hub, each knife
A blade 2 is equipped in film trap 1-1, each 2 lower end of blade contradicts on corresponding insert groove 1-1, and each blade 2 is
Be fixedly connected by fixing screws 3 with broaching tool cutter hub 1, each blade 2 rely on cutting force and fixing screws 3 clamp naturally against
On insert groove 1-1, successively equal difference is increased for position of the multiple insert groove 1-1 on broaching tool cutter hub 1, and 2 position of blade is therewith
It successively gradually rises, to realize when processing the workpiece, does not change knife depth direction, only alongst movement can be real
The purpose for removal workpiece surplus of now gradually broaching, the multiple blade 2 is rectangular knife, and the four edges of each blade 2 are equipped with
Cutting edge 2-1, and each cutting edge 2-1 has cutting anterior angle, reduces cutting resistance, i.e., each blade 2, which tilts, to be set
It sets, and the same angle tilt of multiple blades 2.Each blade 2 uses one of cutting edge 2-1 every time, directly converts after abrasion
Remaining cutting edge 2-1 can be used continuously, i.e., blade 2 indexable four times each, and indexing is convenient, economy with higher
Property.
The multiple insert groove 1-1 or so is successively staggered, and the multiple blade 2 or so is successively staggered.
The multiple blade 2 is all made of hard alloy material, can support that High-speed machining, supported cutting speed are existing
6 times or more of high-speed steel tool.
Successively equal difference increases for position of the multiple blade 2 on broaching tool cutter hub 1.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
