Abstract

The utility model provides a high-efficiency and strong force type milling-cutter which is composed of a handle, large chip pockets, mother teeth, son teeth and small chip pockets. The son teeth are arranged on the mother teeth, and a cutting edge is arranged the son teeth. The oblique angle of the cutting edge on the son teeth which are on the adjacent mother teeth can be designed into the same or the reverse direction. The small chip pockets can also be designed into the same or the reverse direction. The utility model has the great improvement for suppressing the cutting vibration for the balance of cutting force, cutting in a chip dividing way, and removing chips successfully.

Description

The milling-cutter of effective powerful cutting

The utility model relates to a kind of milling-cutter of effective powerful cutting of novelty, belong to the metal cutting tool field.

Milling cutter in the prior art is widely used because of the cutting ability of the uniqueness in the metal cutting field, as the coordinate milling on the various surfaces of various planes, side, shoulder, groove, cut-out processing.The shape of the cutter tooth of all kinds of milling cutters and the design of angle have very crucial influence to the cutting ability of milling cutter, and common milling cutter cutter tooth has straight-tooth, helical teeth and helical tooth.Referring to mechanical engineering manual, the 8th volume, China Machine Press, front page, nineteen eighty-two.Tool Design professional is in long term studies and practice, the milling cutter tooth form of prior art a lot of improvement have been done, do not have under the sufficiently high strength condition but also solve well so far at cutter tooth, increase the cutting edge oblique angle, and have big chip space, to guarantee that chip removal improves stock-removing efficiency smoothly; Having under enough time said conditions of refacing, to reduce the number of times of refacing as far as possible, to prolong cutter life.

The purpose of this utility model is to overcome the deficiency in the prior art, adopts new design concept, has proposed a kind of milling-cutter of high-efficient cutting, has solved the problem that smooth stock-removing efficiency height of chip removal and cutter tooth have enough intensity well.

Content of the present utility model is milling-cutter is designed to mainly can be by shank, big chip pocket, female tooth, sub-tooth and little chip pocket constitute, it is characterized in that having sub-tooth on female tooth, cutting edge is located on the sub-tooth, sub-tooth rake face two ends are the smooth connection of circular arc, cutting edge oblique angle on the sub-tooth on adjacent female tooth can be designed in the same way or oppositely, and Dui Ying little chip pocket also can be designed in the same way or oppositely therewith.

Below with reference to accompanying drawing technical characterictic of the present utility model is described in detail:

Fig. 1 is the sub-sword slotting cutter of rough lumber

Fig. 2 is the sub-sword slotting cutter of a rough lumber profile

Fig. 3 cuts sub-sword slotting cutter profile for essence

Fig. 4 is sub-sword face and side cutter

Fig. 5 is sub-sword conical milling cutter

Fig. 6 is sub-sword curve profile milling cutter

As shown in Figure 1 and Figure 2, the form of the sub-sword slotting cutter of the rough lumber of milling-cutter: constitute by shank 1, big chip pocket 2, female tooth 3, sub-tooth 4 and little chip pocket 5.Sub-tooth 4 is located on female tooth 3, and cutting edge is located on the sub-tooth 4, and the cutting edge of the sub-tooth 4 on same or adjacent female tooth 3 can be designed in the same way or oppositely, and corresponding therewith little chip pocket 5 also can be designed in the same way or oppositely.The thickness of same female tooth 3 can change, and the width that is designed to sub-tooth 4 cutting edges on same female tooth 3 is ascending along cutting direction.In order to raise the efficiency, smear metal is discharged smoothly, be designed to be staggered mutually in sub-tooth 4 positions on female tooth 3, carry out the cutting of branch bits.

As the various forms of Fig. 3, Fig. 4, Fig. 5 and milling-cutter shown in Figure 6, milling-cutter can also be designed to various forms according to the requirement of machined object.

Sub-tooth 4 of the present utility model can be designed to welded type (comprising bonding) or clamped.In order further to improve cutting data, in the life-span of improving blade strength and cutting edge, it is the circular arc heavy-duty tool that the rake face of sub-tooth 4 is designed to the two ends, plane, and front and rear knife face is the plane, is formed naturally the waveform sword on cylindrical.

Of the present utility model to be implemented in milling cutter technical be once big reform, for suppressing cutting vibration, makes the cutting force balance, divides the bits smear metal and improve intensity and life-span, goes out to consider to be worth doing smooth tool and have greatly improved.
