Abstract
The utility model relates to a novel forming cutter for processing stepped holes. The novel forming cutter comprises a cutter shank section and a cutter body section, wherein the cutter body section and the cutter shank section are coaxially integrally formed, and the cutter body section is arranged at the front end part of the cutter shank section; the cutter body section is provided with two steps; a chamfer is formed between every two adjacent steps; two slag discharging slots are symmetrically formed between the end part of the cutter body section and the middle part of the shank section in the axial direction; a cutting edge is formed between each slag discharging slot and the cutter body section; a hole bottom cutting edge for processing hole bottoms is formed between each slag discharging slot and the end face of the cutter body section. The two steps are formed on the cutter body section of the forming cutter, so that the stepped holes can be processed by one working procedure; therefore, the working efficiency is improved; furthermore, the coaxiality of the stepped holes is consistent, so that the processing quality is improved; a symmetric fan-shaped structure is arranged on the end face of the cutter body section, so that processing of the stepped holes and fine processing of the end faces of the hole bottoms can be realized at the same time. The novel forming cutter is simple in structure, scientific and reasonable in design and convenient for processing, and the processing precision and the working efficiency of the stepped holes are greatly improved.
Description
Technical field
The utility model belongs to cutting tool technical field, specifically, is a kind of novel forming cutter for processing step hole.
Background technology
In machined field, often need to use forming cutter to mold members or part carries out reaming processing, the especially processing of stepped hole, need to divide multiple working procedure, and different pore size need prepare a cutter, if stepped hole is blind hole, also need carrying out fine finishining at the bottom of hole.
The shortcoming of above-mentioned processing step hole is: 1, the cutter of preparation is many, and needs the frequent cutter of changing, and improves the cost of charp tool and operating efficiency low; 2, owing to being divided into multiple working procedure processing, cause the concentricity of stepped hole poor, thereby reduced crudy; 3, to after stepped hole completion of processing, also need, to carrying out fine finishining at the bottom of hole, not only to reduce operating efficiency, and the uniformity of processing with hole wall at the bottom of very difficult guarantee hole.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel forming cutter for processing step hole simple in structure, that effectively increase work efficiency is provided.
Scheme of the present utility model is achieved in that
A kind of novel forming cutter for processing step hole, comprise handle of a knife section and cutter hub section, cutter hub section and handle of a knife section are coaxially made into integration and cutter hub section is located at the leading section of handle of a knife section, described cutter hub section is made two steps, between adjacent step, be shaped with chamfering, between described cutter hub section end to handle section middle part, axially symmetry is shaped with two chip areas, between each chip area and cutter hub section, forms blade, forms the hole shear blade at the bottom of machining hole between each chip area and cutter hub section end face.
And described cutter hub section end face is the sector structure with center of circle symmetry, this cutter hub section end face is inclined plane.
And the angle of inclination on described inclined plane is 8-15 degree.
And described angle of inclination is 10 degree.
And the included angle of described chip area is 90 degree.
Advantage of the present utility model and good effect are:
The cutter hub section of this forming cutter is shaped with two steps, therefore can process stepped hole by a procedure, not only improved operating efficiency, and the axiality of stepped hole is consistent, has improved crudy; Cutter hub section end face is made symmetrical sector structure, therefore in stepped hole processing, can carry out the fine finishining of hole bottom face.The utility model is simple in structure, design science is reasonable, is easy to processing, has greatly improved machining accuracy and the operating efficiency of stepped hole.
Brief description of the drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.
For a novel forming cutter for processing step hole, as shown in Figure 1, comprise handle of a knife section 5 and cutter hub section, cutter hub section and handle of a knife section are coaxially made into integration and cutter hub section is located at the leading section of handle of a knife section.
Innovative point of the present utility model is:
Described cutter hub section is made two steps 1 and step 2, between adjacent step, be shaped with chamfering 4, between described cutter hub section end to handle section middle part, axially symmetry is shaped with two chip areas 3, between each chip area and cutter hub section, form blade 6, between each chip area and cutter hub section end face, form the hole shear blade 7 at the bottom of machining hole.
Described cutter hub section end face 8 is the sector structure with center of circle symmetry, and as shown in Figure 2, this cutter hub section end face is the inclined-plane tilting, and this angle of inclination A is 8-15 degree, preferably 10 degree, as shown in Figure 1, therefore can be to carrying out fine finishining at the bottom of hole.
The included angle B of described chip area is 90 degree.
The cutter hub section of this forming cutter is shaped with two steps, therefore can process stepped hole by a procedure, not only improved operating efficiency, and the axiality of stepped hole is consistent, has improved crudy; Cutter hub section end face is made symmetrical sector structure, therefore in stepped hole processing, can carry out the fine finishining of hole bottom face.The utility model is simple in structure, design science is reasonable, is easy to processing, has greatly improved machining accuracy and the operating efficiency of stepped hole.
It is emphasized that; embodiment described in the utility model is illustrative; instead of determinate; therefore the utility model comprises and is not limited to the embodiment described in detailed description of the invention; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
