Abstract
A round knife for machining a multi-step excircle comprises a knife handle and a knife body, wherein both the knife handle and the knife body are cylindrical, the diameter of the knife body is larger than that of the knife handle, the knife handle and the knife body are rigidly fixed into a whole, at least two centrally symmetrical inner blade fixing grooves are formed in the knife body, two protruding parts are arranged on the outer end face of the knife body, centrally symmetrical outer blade fixing grooves are formed in the protruding parts, the inner blade fixing grooves and the outer blade fixing grooves are provided with cutting edges respectively, and the inner blade fixing grooves and the outer blade fixing grooves are arranged in a stepped mode. Compared with the prior art, the round knife has the advantages that the structural design is simple, and the cutting edges are manufactured by welding polycrystalline diamond materials; operation is convenient, working efficiency is improved, and product quality is guaranteed; the rigidity of the knife is improved; the service life of the knife is prolonged; the rejection rate of products is reduced.
Description
Technical field
The utility model relates to machining technique field, the circular cover of especially a kind of many steps of processing cylindrical cutter.
Background technology
Cutter cutter hub is in the past generally segment, and welding cutting edge place material is all removed empty avoiding, causes cutter hub rigidity deficiency, and cutting edge roundness adds and easily produces shake knife mark on surface at product man-hour, causes product rejection rate high, has a strong impact on the quality of product.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For overcoming the above-mentioned problems in the prior art, the purpose of this utility model is to provide that a kind of hardness is high, the circle cover cutter of many steps of processing cylindrical of adequate rigidity, good stability.
The utility model is realized above-mentioned purpose by following technological means:
The circular cover of a kind of many steps of processing cylindrical cutter, comprise handle of a knife and cutter hub, described handle of a knife and cutter hub are cylinder, and the diameter of described cutter hub is greater than the diameter of described handle of a knife, described handle of a knife and cutter hub rigidity are solidified as a whole, and are provided with at least two centrosymmetric inner blade holddown grooves in described cutter hub; The outer face of described cutter hub is provided with two juts, and those juts are provided with centrosymmetric outer blade holddown groove; On described inside and outside blade holddown groove, cutting edge roundness is all installed; Described inside and outside blade holddown groove is stepped.
Preferably, described cutter hub is provided with cutting edge roundness empty avoiding place corresponding to inner blade holddown groove.
Compared with prior art, the advantage that the utility model has is:
1, structural design is simple, utilizes welding dimond synneusis material to make cutting edge technology;
2, easy to operate, increase work efficiency, ensure product [31];
3, improve cutter rigidity;
4, improve cutter life;
5, reduce product rejection rate.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In figure, each label respectively: (10) handle of a knife, (20) cutter hub, (21) inner blade holddown groove, (22) jut, (23) outer blade holddown groove, (24) cutting edge roundness, (25) cutting edge roundness empty avoiding place.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Please refer to Fig. 1, the circular cover of a kind of processing of the utility model many steps cylindrical cutter, comprise handle of a knife 10 and cutter hub 20, the cylinder that described handle of a knife 10 and cutter hub 20 are, the diameter of described cutter hub 20 is greater than the diameter of described handle of a knife 10, described handle of a knife 10 is solidified as a whole with cutter hub 20 rigidity, is provided with at least two centrosymmetric inner blade holddown grooves 21 in described cutter hub 20; The outer face of described cutter hub 20 is provided with two juts 22, and those juts are provided with centrosymmetric outer blade holddown groove 23; On described inside and outside blade holddown groove, cutting edge roundness 24 is all installed; Described inside and outside blade holddown groove is stepped, and by above-mentioned structural design, described cutter hub adopts 40Cr material, improves cutter integral rigidity; Cutting edge roundness adopts dimond synneusis material, improves tartness degree of tool cutting edge.
Described cutter hub is provided with cutting edge roundness empty avoiding place 25 corresponding to inner blade holddown groove, is convenient to the cutting edge roundness on inner blade holddown groove 21 to carry out reconditioning.
Making step of the present utility model is: 1, get one section of 40Cr materials processing and become cutter hub, the reserved 0.1mm fine grinding of shank end; 2, with vertical machining centre or empty avoiding place of line cutting processing cutter hub cutting edge, reprocessing blade holddown groove; 3, cutter hub is carried out to modifier treatment, improve cutter hub hardness; 4, cutting edge roundness is welded on blade holddown groove; 5, fine grinding shank end; 6, fine grinding dimond synneusis material is made cutting edge roundness, ensures that cutting edge roundness is concentric with handle of a knife, completes.
In sum, the utility model is by above-mentioned structural design, solve the problem existing in conventional art, owing to only removing cutter hub cutting edge empty avoiding place material, thereby greatly improve cutter hub rigidity, improve product machined surface roughness and dimensional stability, ensured product quality, solved cutting edge roundness and produced shake knife mark at product finished surface and affect a difficult problem for product quality.
Electronics shelves have fallen " product " word, and scanning shelves are revised, above give the correct time and please be careful.
