Abstract
The utility model discloses a three swords sword for aluminium, including the handle of a knife, handle of a knife no. 1 is served and is provided with the tool bit, tool bit upper end be provided with three end sword and correspond and be spiral helicine side tool sword, the helical angle an of side tool sword is 25 35, has spiralization chip groove between the side tool sword installed circular arc relief angle b on the end sword and has been 11 13. The utility model has the advantages of novel in design, simple structure are fit for smart rough machining, and intensity is high, and is durable.
Description
Technical field
The utility model is related to cutting-tool engineering field, more particularly to a kind of three swords aluminium knife.
Background technology
In machining, cutter is the indispensable critical piece of machine tooling, and the quality of cutter quality has influence on itself
Service life, also have influence on the quality and production efficiency of machining.When being processed to aluminium, because aluminium hardness
It is softer, knife is easily glued in cutting, cause cutting resistance big, tool wear is serious, and cutting speed is slow, and cutter is easily damaged, work
The problems such as there is burr in part surface.
Utility model content
The purpose of this utility model is to provide a kind of three swords aluminium knife for the deficiencies in the prior art, and the three swords aluminium is used
Knife is novel in design, simple structure, is adapted to essence roughing, and intensity is high, durable.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions.
A kind of three sword aluminium knives, include handle of a knife, and cutter head is provided with handle of a knife one end, and cutter head upper end is provided with three end swords
And corresponding and spiral side tool sword, helical angle a of side tool sword is 25-35 °, spiralization chip area between side tool sword,
End sword upper end is equiped with circular arc relief angle b for 11-13 °.
Wherein, the handle of a knife rear end is provided with chamfering c.
Wherein, helical angle a of the side tool sword is 30 °.
Wherein, the end sword upper end is equiped with circular arc relief angle b for 12 °.
The beneficial effects of the utility model are：A kind of three swords aluminium knife described in the utility model, includes handle of a knife, handle of a knife
Cutter head is provided with one end, cutter head upper end is provided with three end swords and corresponding and spiral side tool sword, the spiral shell of side tool sword
Swing angle a is 25-35 °, spiralization chip area between side tool sword, and end sword upper end is equiped with circular arc relief angle b for 11-13 °.This practicality
It is new with novel in design, simple structure, be adapted to essence roughing, high, the durable advantage of intensity.
Description of the drawings
The utility model is further detailed below with accompanying drawing, but the embodiment in accompanying drawing do not constitute it is right
Any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view of the utility model cutter head radial direction.
Include in Fig. 1-2：
1 --- handle of a knife 2 --- cutter head
21 --- end sword 22 --- side tool swords
23 --- chip area.
Specific embodiment
The utility model is illustrated with reference to specific embodiment.
As shown in Figure 1-2, a kind of three swords aluminium knife, includes handle of a knife 1, cutter head 2 is provided with the one end of handle of a knife 1, on cutter head 2
End is provided with three end swords 21 and corresponding and spiral side tool sword 22, and helical angle a of side tool sword 22 is 25-35 °, side tool
Spiralization chip area 23 between sword 22, the end upper end of sword 21 is equiped with circular arc relief angle b for 11-13 °.
Further, the rear end of the handle of a knife 1 is provided with chamfering c.
Preferred as the present embodiment, helical angle a of the side tool sword 22 is 30 °.
Further, the upper end of end sword 21 is equiped with circular arc relief angle b for 12 °.
Need to further explain, the utility model adopts helical angle a of side tool sword 22 for 25-35 ° of design, strengthens knife
Tool intensity, is conducive to shallow slot to process, and adopts the upper end of end sword 21 to be equiped with the design that circular arc relief angle b is for 11-13 °, is conducive to dispersion
Cutting force, is conducive to roughing, therefore the utility model has novel in design, simple structure, is adapted to essence roughing, and intensity is high, resistance to
Advantage.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, will change in specific embodiments and applications, this specification content should not be construed as
To restriction of the present utility model.
