Description
Technical field
The utility model relates to cutting-tool engineering fields, and in particular to a kind of wolfram steel milling cutter.
Background technique
The end sword of existing milling cutter is integrally formed, and when boring some materials that the material is soft, the stress of this end sword is not
Equilibrium influences drilling effect.
Utility model content
The purpose of this utility model is to provide a kind of wolfram steel milling cutter, end sword stress equalization, drilling effect is good.
To achieve the above object, the utility model provides the following technical solutions:
A kind of wolfram steel milling cutter, including for installation knife handle and with the integrally formed cutter head of knife handle, cutter head be equipped with three
Prolong the spiral-shaped blade of its length direction arrangement, the end face of cutter head be equipped with three first end swords being evenly arranged at 120 degree intervals,
Second end sword and third end sword, towards identical, first end sword is equipped with for the cutting edge of first end sword, second end sword and third end sword
One notch, second end sword are equipped with the second notch, and third end sword is equipped with third notch, and cutter head rotates a circle, the first notch, the
Two notches and third notch be formed by notch track by first end sword, second end sword or third end tooth shape at cutting edge track institute
Covering.
Preferably, blade is equipped with notch.
The working principle of the utility model are as follows: first end sword, second end sword and third end sword are respectively equipped with notch, so that the
An annular region is respectively cut in one end sword, second end sword and third end sword, ultimately forms a complete cut surface region,
In boring procedure, first end sword, second end sword and third end sword are by resistance about the same, therefore, first end sword, second
Hold sword and third end sword stress equalization, drilling effect good.
The utility model has the following beneficial effects: its end sword stress equalization, drilling effect are good.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model cutter head end sword.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
The technical solution of the utility model specific implementation is:
As shown in Figure 1,
A kind of wolfram steel milling cutter, including for installation knife handle and with the integrally formed cutter head 1 of knife handle, cutter head 1 be equipped with three
Item prolongs the spiral-shaped blade of its length direction arrangement, and the end face of cutter head 1 is equipped with three and is spaced the first end being evenly arranged at 120 degree
Sword 21, second end sword 22 and third end sword 23, the cutting edge of first end sword 21, second end sword and third end sword 23 is towards identical, and
One end sword 21 is equipped with the first notch 31, and second end sword is equipped with the second notch 32, and third end sword 23 is equipped with third notch 33,
Cutter head 1 rotates a circle, the first notch 31, the second notch 32 and third notch 33 be formed by notch track by first end sword 21,
The cutting edge track that second end sword 22 or third end sword 23 are formed is covered.
Blade is equipped with notch.
The working principle of the utility model are as follows: first end sword 21, second end sword 22 and third end sword 23 are respectively equipped with notch,
So that an annular region is respectively cut in first end sword 21, second end sword 22 and third end sword 23, one is ultimately formed completely
Cut surface region, in boring procedure, first end sword 21, second end sword 22 and third end sword 23 are by resistance about the same
Power, therefore, 23 stress equalization of first end sword 21, second end sword 22 and third end sword, drilling effect is good.
The utility model has the following beneficial effects: its end sword stress equalization, drilling effect are good.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
