Description

End milling cutter

Technical Field

The utility model relates to an end mill technical field, in particular to end mill.

Background

In the machining process, an end mill is often used for milling a workpiece so as to achieve the purposes of slotting, milling a side face, milling a stepped face and the like.

The current milling cutter only has a cutting edge positioned on the side wall and a main edge positioned on the end surface, and the structure has the problem that the point of the main edge is worn quickly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an end mill has wear-resisting good and efficient effect of cutting.

The above technical object of the present invention can be achieved by the following technical solutions: the multifunctional knife comprises a knife handle, be connected with the blade on the handle of a knife, the outer wall connection of blade has rotatory cutting sword, the one end that the handle of a knife was kept away from to the blade is connected with first tool bit, second tool bit and third tool bit, first tool bit, second tool bit and the coaxial setting of third tool bit, just the length of first tool bit, second tool bit and third tool bit reduces in proper order, just the circumference at the outer wall place of first tool bit, second tool bit and third tool bit reduces in proper order.

Through adopting above-mentioned technical scheme, through setting up the rotatory cutting sword of different density, increase under the intensity condition of blade and cutting efficiency high, the cutting time is short under the same condition, reduces the wearing and tearing time, simultaneously, sets up different first sword, second tool bit and third tool bit, and the three acts on differently, reduces wearing and tearing.

The utility model discloses a further set up to: the knife handle and the knife body are coaxially arranged, and the knife handle and the knife body are integrally formed.

The utility model discloses a further set up to: the density of the rotary cutting blades decreases from left to right on the blade body.

By adopting the technical scheme, the side cutting effect is good, the cutting time is short, and the abrasion is reduced.

The utility model discloses a further set up to: the circumference of the outer wall of the third cutter head is coincided with the outer wall of the cutter body.

The utility model discloses a further set up to: the rotary cutting knife, the first knife head, the second knife head, the third knife head and the knife body are integrally formed.

The utility model discloses a further set up to: the first cutter head, the second cutter head and the third cutter head are in arc trapezoid shapes.

The utility model has the advantages that: through setting up the rotatory cutting sword of different density, increase under the intensity condition of blade and cutting efficiency high, the cutting time is short under the same condition, reduces the wearing and tearing time, simultaneously, sets up different first sword, second tool bit and third tool bit, and the three effect is different, reduces wearing and tearing.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Fig. 1 is a schematic diagram of the present invention.

Fig. 2 is a side view of the first, second and third tool bits of the present invention.

In the figure, 1, a knife handle; 2. rotating the cutting blade; 3. a first cutter head; 4. a second cutter head; 5. a third cutter head; 6. a knife body.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to specific embodiments. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, an end mill includes a shank 1, a blade 6 connected to the shank 1, the shank 1 and the blade 6 being coaxially disposed, and the shank 1 and the blade 6 being integrally formed; the outer wall connection of blade 6 has rotatory cutting sword 2, and rotatory cutting sword 2 reduces from a left side to right density on blade 6, so under the same rotational speed, the rotatory cutting sword 2 of high density is efficient, compares in prior art's end mill blade 6 intensity better.

One end of the cutter body 6, which is far away from the cutter handle 1, is connected with a first cutter head 3, a second cutter head 4 and a third cutter head 5, the circumference of the outer wall of the third cutter head 5 coincides with the outer wall of the cutter body 6, the first cutter head 3, the second cutter head 4 and the third cutter head 5 are coaxially arranged, the lengths of the first cutter head 3, the second cutter head 4 and the third cutter head 5 are sequentially reduced, the circumferences of the outer walls of the first cutter head 3, the second cutter head 4 and the third cutter head 5 are sequentially reduced, the rotary cutting cutter 2, the first cutter head 3, the second cutter head 4 and the third cutter head 5 are integrally formed with the cutter body 6, and the first cutter head 3, the second cutter head 4 and the third cutter head 5 are in arc trapezoidal shapes.

The utility model discloses, first tool bit 3, the length of second tool bit 4 and third tool bit 5 reduces in proper order, consequently first tool bit 3 cuts certain degree of depth when the cutting, then second tool bit 4 and third tool bit 5 also cut certain degree of depth respectively, first tool bit 3, second tool bit 4 and third tool bit 5 exert different effects respectively, the cutting effect is good and each plays its own role, compared with the prior art, can not cause the serious condition of a certain tool bit wearing and tearing, on the same principle, first tool bit 3, the circumference at the outer wall place of second tool bit 4 and third tool bit 5 reduces in proper order, then during the side shallow cutting, third tool bit 5 cuts certain degree of depth, first tool bit 3, second tool bit 4 also cuts certain degree of depth respectively, first tool bit 3, second tool bit 4 and third tool bit 5 exert different effects respectively, the cutting effect is good and each plays its role, compared with the prior art, can not cause the serious condition of a certain tool bit wearing and tearing.
