Between adjacent blade, blade and chip area are arranged in the shape of a spiral on cutter hub, and its several blade and chip area are with identical spiral shell
Swing angle is symmetrically disposed on cutter hub.
Plain cutter is usually 2 swords, easily occurs viscous bits during processing plastics, causes processing surface roughness bad around bits, very
To breaking is caused, reason is plastics poor thermal conductivity, and conference of generating heat during tool sharpening causes plastic melt to cause viscous knife, twines bits, leads
It is caused to carry out normal work.
Utility model content
The purpose of this utility model is to provide for being avoided that the viscous single-blade milling considered to be worth doing and twine bits situation during a kind of processing plastics
Knife structure.
To achieve these goals, the utility model proposes a kind of single-blade milling cutter structure, including handle of a knife, chip breaking portion and hollow
Spiral helicine cutting portion, the handle of a knife is connected by the chip breaking portion with the cutting portion；The side of the cutting portion forms list
One cutting edge, the hollow parts of curling form single chip area, and the chip area extends to the cutting edge from the chip breaking portion
Blade tip at；The chip area is provided with a chip-breaker at cutting edge blade tip, and the chip-breaker is located at the cutting edge away from blade tip
At 1.2mm, the chip-breaker forms an angle theta with the axis of described cutting portion；The core thickness of the cutting portion is that cutting portion is straight
The 55% of footpath.
Further, in a kind of described single-blade milling cutter structure, the handle of a knife, chip breaking portion and cutting portion are integrated structure
Make.
Further, in a kind of described single-blade milling cutter structure, the angle theta is 45 °.
Further, in a kind of described single-blade milling cutter structure, the helical angle of the chip area is 25 °.
Further, in a kind of described single-blade milling cutter structure, it is provided with one between the handle of a knife and the chip breaking portion and inclines
Oblique angle η is 30 ° of hypotenuse.
Further, in a kind of described single-blade milling cutter structure, between the chip breaking portion and the cutting portion one is provided with
Inclination angle μ is 15 ° of hypotenuse.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in：For processing plastics, easy heat radiation is not easy
The characteristics of viscous knife, integrally using the single-blade chip design that chip removal is smooth, front end arranges chip-breaker to cutter, effectively reduces viscous bits and twines
The occurrence of bits；The core thickness of cutting portion is the 55% of cutting portion diameter, the size of rational control chip discharge groove, beneficial to row
Bits.

Fig. 2 is the schematic diagram that certain angle is circumferentially turned over relative to Fig. 1；
Fig. 3 is a kind of left view of the cutting portion of single-blade milling cutter structure in Fig. 1.
Specific embodiment
As shown in figure 1, the utility model proposes a kind of single-blade milling cutter structure, including handle of a knife 1, chip breaking portion 2 and hollow spiral shell
The cutting portion 3 of rotation shape, the handle of a knife 1 is connected by the chip breaking portion 2 with the cutting portion 3.In the present embodiment, its preferred side
Case is：The handle of a knife 1, chip breaking portion 2 and cutting portion 3 are integrated construction, and integral manufacturing is convenient and simple, and Practical Performance is good.It is described
The hypotenuse that an inclination angle η is 30 ° is provided between handle of a knife 1 and the chip breaking portion 2, is set between the chip breaking portion 2 and the cutting portion 3
There is the hypotenuse that an inclination angle μ is 15 °, inclination angle η is that 30 ° of hypotenuse has transitional function, and inclination angle μ is that 15 ° of hypotenuse has
Chip breaking and transitional function, discharge after can preferably be blocked chip, the occurrence of effectively reducing viscous bits and twine bits.
As shown in Figure 1 to Figure 3, in the present embodiment, the side of the cutting portion 3 forms single cutting edge 31, curling
Hollow parts form single chip area 32, and the chip area 32 is extended at the blade tip of the cutting edge 31 from the chip breaking portion 2；
The chip area 32 is provided with a chip-breaker 33 at the blade tip of cutting edge 31, and the chip-breaker 33 is located at the cutting edge 31 away from blade tip
At 1.2mm, the chip-breaker 33 forms an angle theta with the axis of described cutting portion 3, and the angle theta is 45 °.Chip-breaker
33 design, makes chip that extruding is bent at angle theta, and the shape that finally fragmentates flies out, and can effectively reduce viscous bits and twine bits feelings
