Abstract
The utility model belongs to the field of cutters, and particularly relates to an integral alloy T-shaped milling cutter which is high in strength and capable of being used for cutting specially-shaped grooves and specially-shaped wall surfaces. The integral alloy T-shaped milling cutter comprises a cylindrical cutter bar. The milling cutter is characterized in that a frustum-shaped cutting part is arranged at the front end of the cutter bar, the cutting part extends backwards to form an annular cutting part, four cutting edges are evenly arranged at the cutting part, chip removal grooves are formed between the adjacent cutting edges and extend onto the cutter bar, the diameter of a small end of the frustum-shaped cutting part is 11 mm, the diameter of a large end is 16 mm, and the width of the annular cutting part is 1.16 mm. The cutting parts and a handle part of the milling cutter are molded integrally, so that the milling cutter has the better overall rigidity, the defect of breakage of traditional welding cutters is overcome, and the service life of the cutter is prolonged; in addition, according to the milling cutter, shapes of the cutting parts are improved.
Description
Technical field
The utility model belongs to cutting tool field, and particularly a kind of intensity is high, can cut the T-shaped milling cutter of Integral alloy of special-shaped groove and special-shaped wall.
Background technology
Existing T-shaped milling cutter generally adopts combined type to process, it is welded by cutting portion and handle of a knife portion, and in process, welding position is subject to the impact of cutting force continuously, welding position easily lost efficacy, the integral rigidity deficiency of cutter, affects service life of cutter, and the side cutting face of existing T-shaped milling cutter is generally and faces directly in addition, the shape matching of cutting is single, and the cutting resistance being subject in working angles is excessive, cause blade rapid wear, the service life of cutter is shorter.
Utility model content
The utility model is for the deficiencies in the prior art, and the utility model has designed a kind of handle of a knife and the T-shaped milling cutter of the integrated Integral alloy of cutting portion.
The utility model is achieved through the following technical solutions:
The T-shaped milling cutter of Integral alloy, it comprises columned knife bar, it is characterized in that: the front end of described knife bar is provided with frustum cutting portion, cutting portion extends back and is provided with annular cutting portion, uniformly on described cutting portion is provided with four cutting edges, between adjacent cutting edge, is provided with chip area, chip area extends on knife bar, the end diameter of described frustum cutting portion is 11mm, and outside diameter is 16mm, and the width of annular cutting portion is 1.16mm.
The conical surface angle of described frustum cutting portion is 62 °.
Between described knife bar and frustum cutting portion, be also provided with linkage section, the diameter of described linkage section is less than knife bar and frustum cutting portion.
The conical surface of stepping down that has also been provided with the effect of stepping down on the guide rod of described knife bar and linkage section junction, the angle of the described conical surface of stepping down is 60 °.
In sum, the utlity model has beneficial effect:
Cutting portion of the present utility model and handle of a knife portion adopt one-body molded, there is good integral rigidity, overcome the defect of the fracture of traditional welding cutter existence, extended the service life of cutter, the utility model improves the shape of cutting portion simultaneously, is provided with the cutting portion of frustum, can complete the processing of special-shaped T-shaped groove, and the resistance that taper cutting edge can reduce to be subject in working angles, reduces the wearing and tearing of cutter, the service life of having improved cutter.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the utility model is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Figure 1 shows that structural representation of the present utility model;
In figure, 1 is frustum cutting portion, and 2 is annular cutting portion, and 3 is linkage section, and 4 is the conical surface of stepping down, and 5 is knife bar.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The T-shaped milling cutter of Integral alloy as shown in Figure 1, it comprises columned knife bar 5, it is characterized in that: the front end of described knife bar 5 is provided with frustum cutting portion 1, frustum cutting portion 1 extends back and is provided with annular cutting portion 2, uniformly on described cutting portion is provided with four cutting edges, between adjacent cutting edge, is provided with chip area, chip area extends on knife bar, the end diameter of described frustum cutting portion 1 is 11mm, and outside diameter is 16mm, and the width of annular cutting portion is 1.16mm.
The conical surface angle of described frustum cutting portion 1 is 62 °.
Between described knife bar and frustum cutting portion, be also provided with linkage section 3, the diameter of described linkage section 3 is less than knife bar and frustum cutting portion.
The conical surface 4 of stepping down that has also been provided with the effect of stepping down on the guide rod of described knife bar 5 and linkage section 3 junctions, the angle of the described conical surface of stepping down is 60 °.
In sum, the utlity model has beneficial effect:
Cutting portion of the present utility model and handle of a knife portion adopt one-body molded, there is good integral rigidity, overcome the defect of the fracture of traditional welding cutter existence, extended the service life of cutter, the utility model improves the shape of cutting portion simultaneously, is provided with the cutting portion of frustum, can complete the processing of special-shaped T-shaped groove, and the resistance that taper cutting edge can reduce to be subject in working angles, reduces the wearing and tearing of cutter, the service life of having improved cutter.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
