Abstract
The utility model relates to a forming knife for processing step holes. The forming knife comprises a knife handle and a knife body, wherein the knife body is integrated with the knife handle and arranged at the end part of the knife handle; a step section is arranged at the rear end of the knife body; two chip discharging grooves are formed in the outer edge from the knife body to the knife handle in an axial symmetry manner; a knife edge section and a guide section which are symmetric to each other are formed between each chip discharging groove and the end surface of the knife body; the edge of each knife edge section is axially embedded with a cutting edge made of diamond; a step hole edge made of the diamond is axially embedded between the step section at the rear end of the cutting edge and the chip discharging groove; a chamfered edge made of the diamond is axially embedded between the front end part of the knife handle and the chip discharging groove. The forming knife is simple in structure, scientific and reasonable in design, and easy to process; the processing precision and the working efficiency are greatly improved.
Description
Technical field
The utility model belongs to cutting tool technical field, specifically, is a kind of forming cutter for processing step hole.
Background technology
In machined field, often need to use forming cutter to mold members or part carries out fine finishining, the especially processing of stepped hole, need to divide multiple working procedure, and different pore size need be prepared a cutter.
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, cutter is generally Hardmetal materials, and service life is short, need often to change cutter, greatly reduces operating efficiency.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, long service life, the effective forming cutter for processing step hole of increasing work efficiency are provided.
Scheme of the present utility model is achieved in that
A kind of forming cutter for processing step hole, comprise handle of a knife and cutter hub, cutter hub and handle of a knife are made into integration and cutter hub is located at the end of handle of a knife, the rear end of described cutter hub is shaped with a step section, described cutter hub to the axial symmetry of outer rim of handle of a knife is shaped with two chip areas, between each chip area and cutter hub end face, form symmetrically arranged blade section and guide section, the cutting edge that a diamond is made is all axially inlayed at described blade section edge, between the step section of this cutting edge rear end and chip area, axially inlay the stepped hole sword that a diamond is made, between described handle of a knife section leading section and chip area, axially inlay the chamfering blades that a diamond is made.
And the length of described blade section is greater than the length of guide section.
And described cutter hub end face is the inclined-plane of an inclination, the angle of inclination of described cutter hub section blade section is 8-10 degree; The angle of inclination of described cutter hub section guide section is 10-13 degree.
And the angle of inclination of described blade section is 9 degree; The angle of inclination of described guide section is 12 degree.
And described cutter hub end face is coaxially shaped with a locating hole.
Advantage of the present utility model and good effect are:
Between the cutter hub of this forming cutter and handle of a knife, one is shaped with reaming section, therefore can process stepped hole by a procedure, not only improved operating efficiency, and the axiality of stepped hole is consistent, has improved crudy; Described cutting edge, stepped hole sword and chamfering blades are diamond, have effectively improved the service life of cutter; The length of described blade section is greater than the length of guide section, thereby has effectively improved machining accuracy.The utility model is simple in structure, design science is reasonable, is easy to processing, has greatly improved machining accuracy and operating efficiency.
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 forming cutter for processing step hole, as shown in Figure 1, comprise handle of a knife 7 and cutter hub 3, cutter hub and handle of a knife are made into integration and cutter hub is located at the end of handle of a knife.
Innovative point of the present utility model is:
1, the rear end of described cutter hub is shaped with a step section 5, described cutter hub to the axial symmetry of outer rim of handle of a knife is shaped with two chip areas 2, between each chip area and cutter hub end face 8, form symmetrically arranged blade section A and guide section B, as shown in Figure 2, the cutting edge 1 that a diamond is made is all axially inlayed at described blade section edge, between the step section of this cutting edge rear end and chip area, axially inlay the stepped hole sword 4 that a diamond is made, between described handle of a knife section leading section and chip area, axially inlay the chamfering blades 6 that a diamond is made.By being shaped with step section in the rear end of cutter hub, therefore can process stepped hole by a procedure, not only improve operating efficiency, and the axiality of stepped hole is consistent, improve crudy, described cutting edge, stepped hole sword and chamfering blades are diamond, have effectively improved the service life of cutter.
2,, in order to improve machining accuracy, the length of described blade section A is slightly larger than the length of guide section B.
3, the inclined-plane that described cutter hub end face is an inclination, the angle of inclination D of described cutter hub section blade section is 8-10 degree, preferably 9 degree; The angle of inclination C of described cutter hub section guide section is 10-13 degree, preferably 12 degree.
4, described cutter hub end face is coaxially shaped with a locating hole 9, can fast forming cutter and preprocessing hole be positioned.
Between the cutter hub of this forming cutter and handle of a knife, one is shaped with reaming section, therefore can process stepped hole by a procedure, not only improved operating efficiency, and the axiality of stepped hole is consistent, has improved crudy; Described cutting edge, stepped hole sword and chamfering blades are diamond, have effectively improved the service life of cutter; The length of described blade section is greater than the length of guide section, thereby has effectively improved machining accuracy.The utility model is simple in structure, design science is reasonable, is easy to processing, has greatly improved machining accuracy and operating efficiency.
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.
