Description
Technical field
The utility model relates to machining tool fields, are a kind of three sword rose cutters specifically.
Background technique
Rose cutter is the dedicated tool that manufacturing industry is used to be contoured, and existing rose cutter is two-edged and four swords mostly
Two kinds of structures (referring to Fig. 2, Fig. 3) are rigid not using the rose cutter of two-edged structure under certain special working conditions
Foot, is also easy to produce chatter mark；And rigid requirements are although met with the rose cutter of four sword structures, but it is inadequate to have its chip space
The case where, cause point of a knife easily to collapse scarce.So in the case where two-edged rose cutter and four sword rose cutters cannot be applicable in, most preferably
Selection be exactly to be processed using three sword rose cutters of three sword structures, however existing three swords rose cutter is all made of single-blade
The structure (referring to Fig. 4) at center is crossed, its is thin in ball head split pole for the rose cutter of this structure, seriously affects making for cutter
Use the service life.
It is existing in order to guarantee the ball-type profile tolerance integrality of milling cutter bulb end sword simultaneously in the design of rose cutter
Ball end mill structure all uses double long toothings of two-edged or four swords, but under the special operation conditions such as milling forming tank, two-edged and four
The disadvantages of different weakness is all individually present in the rose cutter of sword structure, and piece surface is caused to generate chatter mark.In this case
Best selection using three sword structures, but its ball-type integrality of the bulb end of existing three swords structure there is a problem of it is very big,
Using single long toothing, bulb part is too thin, seriously affects the service life of cutter.
Utility model content
The purpose of this utility model is to provide a kind of end sword structures of three sword rose cutters, to overcome three common sword balls
Head milling cutter its bulb part cannot bear greater impact power, and bulb center intensity is low, three sword rose cutter service life short problem.
To solve the above-mentioned problems, the utility model uses following technological means:
A kind of rose cutter, including knife handle and knife bar are provided with the first helical milling sword, the second helical milling sword on the knife bar
End with third helical milling sword, the first helical milling sword, the second helical milling sword and third helical milling sword is respectively first end
Sword, second end sword and third end sword；
The first end sword, second end sword and third end sword are in bulb end sword structure；
The first end sword, second end sword and third end sword cross center setting.
Preferably, the angle formed between adjacent two-edged between the first end sword, second end sword and third end sword
It is different.
Further, the first end sword and the second end tooth shape at angle α be 110 ° ~ 120 °, the second end
Sword and third end tooth shape at angle β be 120 ° ~ 130 °, on the circumference of the bulb end sword structure, remaining angle of circumference
For the first end sword and third end tooth shape at angle γ.
Further, the surface of the knife bar is along the first helical milling sword, the second helical milling sword and third spiral shell
The hand of spiral of rotation milling sword is provided with chip pocket.
Further, the cross diameter of the bulb end sword structure is greater than the cross diameter of the knife bar.
Further, the knife handle, the knife bar, the first helical milling sword, the second helical milling sword and institute
It states third helical milling sword and is all made of cemented carbide material and be made.
The utility model at least has one of following beneficial effect compared with three common sword rose cutters:
1, using the design of three sword structures, i.e., the first helical milling sword, the second helical milling sword and third spiral shell are set on knife bar
Rotation milling sword, by using three swords to the structure at center, the i.e. second end of the first end sword of the first helical milling sword, the second helical milling sword
The third end sword of sword and third helical milling sword crosses center setting, while three kinds of ends above-mentioned sword is in the structure of bulb end sword.
This structure can take into account ball-type profile tolerance well and hold the intensity at sword center, to guarantee the complete of end sword ball-type profile tolerance
While becoming second nature, the intensity at bulb end sword center is taken into account, overcoming its bulb part of three sword rose cutters cannot bear compared with favourable opposition
Power is hit, bulb center intensity is low, three sword rose cutter service life short problem.
2, the first end sword of three sword rose cutters, second end sword and third end sword are designed to dissymmetrical structure, i.e.,
α, β, γ have different angles, design very good solution work in-process in this way and lead to the problem of chatter mark, can be effectively suppressed and add
The resonance generated during work, to improve the quality of processing.
