Background technology
In prior art, ceramic tip normally adopts ceramic material by mould molding, its structure is as shown in Fig. 1, Fig. 1-1, Fig. 1-2 and Fig. 1-3, be made up of blade base 10 and cutter tooth 20, blade base 10 forms oblique triangular prism 30 near the part of cutter tooth 20, and bottom surface and two sides of oblique triangular prism 30 directly form cutter tooth 20.Such cutter tooth 20, forms the corner cut β of both sides between side and bottom surface by two, corner cut β is generally between 60-80 degree, and cutting effect is undesirable.
If reduced by the corner cut β of cutter tooth 20 both sides especially to promote cutting effect, then tiltedly triangular prism 30 also will tilt more, and cause blade base 10 too thin near the part of cutter tooth 20, affect the intensity of whole blade, cause blade easily to rupture, service life is short.
Therefore, existing ceramic tip structure existing defects, has necessity of improvement really.
Utility model content
The purpose of this utility model is to provide a kind of one-time formed blade structure, makes cutting efficiency higher.
To achieve these goals, solution of the present utility model is:
A kind of one-time formed blade structure, be made up of blade base and cutter tooth, the front portion of blade base directly forms triangular pyramidal, a conical surface of triangular pyramidal is connected with the front portion of blade base, the bottom surface of triangular pyramidal and two other conical surface form cutter tooth, two corner cuts forming cutter tooth both sides between the conical surface and bottom surface.
Described corner cut is between 30-65 degree.
Lead angle is formed between two conical surfaces of described formation cutter tooth.
Two conical surfaces of described formation cutter tooth concave in cambered surface.
Described blade base forms reinforcement between corresponding two cutters tooth.
On described blade base corresponding cutter tooth two conical surfaces between form reinforcement, the both sides of reinforcement extend to and connect together with two conical surfaces.
Two conical surfaces of described cutter tooth are outwards bent to form low-angle corner cut near bottom surface.
After adopting such scheme, the utility model forms cutter tooth by the bottom surface of triangular pyramidal with two other conical surface, replace the bottom surface of tiltedly triangular prism in prior art and two sides directly to form cutter tooth, under the prerequisite ensureing cutter tooth intensity, the corner cut of cutter tooth both sides can be reduced as far as possible, increase the sharp degree of cutter tooth, make cutting efficiency higher, and this structure does not change the thickness of blade base, the intensity of whole blade is not affected, blade long service life yet.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

Label declaration
Blade base 10, cutter tooth 20, oblique triangular prism 30, corner cut β;
Blade base 1, reinforcement 11, reinforcement 12, cutter tooth 2, triangular pyramidal 3, the conical surface 31,33 and 34, bottom surface 32, lead angle 35, corner cut γ.
Detailed description of the invention
As shown in Fig. 2-1 to Fig. 6-3, the one-time formed blade structure of one that the utility model discloses, be made up of blade base 1 and cutter tooth 2, the front portion of blade base 1 directly forms triangular pyramidal 3, a conical surface 31 of triangular pyramidal 3 is connected with the front portion of blade base 1, the bottom surface 32 of triangular pyramidal 3 and two other conical surface 33,34 form the corner cut γ forming cutter tooth 2 both sides between cutter tooth 2, two conical surfaces 33,34 and bottom surface 32.
The utility model is under the prerequisite ensureing cutter tooth 2 intensity, and can reduce the corner cut γ of cutter tooth 2 both sides as far as possible, corner cut γ can between 30-65 degree, increase the sharp degree of cutter tooth 2, make cutting efficiency higher, and, this structure does not change the thickness of blade base, blade long service life.
In order to optimize structure, as shown in Fig. 3-1 to Fig. 3-3, the utility model can form lead angle 35 between two conical surfaces 33,34 forming cutter tooth 2, increase the intensity of cutter tooth 2, and two conical surfaces 33,34 forming cutter tooth 2 are concaved in cambered surface, reduce the corner cut γ of cutter tooth 2 both sides further, make cutting efficiency higher.
As shown in Fig. 4-1 to Fig. 4-3, the utility model can form reinforcement 11 between corresponding two cutters tooth 2 on blade base 1, increase the intensity of blade base 1, prevent blade breakages, between two conical surfaces 33,34 forming cutter tooth 2, form lead angle 35, increase the intensity of cutter tooth 2, longer service life, and two conical surfaces 33,34 forming cutter tooth 2 are concaved in cambered surface, reduce the corner cut γ of cutter tooth 2 both sides further, make cutting efficiency higher.
