Abstract
The utility model relates to a broaching and chamfering integrally-formed tool. The broaching and chamfering integrally-formed tool comprises a tool holder and a tool body, wherein the tool body and the tool holder are formed integrally; the tool body is arranged at one end part of the tool holder. The broaching and chamfering integrally-formed tool is characterized in that a chamfering section is formed integrally between the tool body and the tool holder; two chip discharge grooves are formed in the peripheries of the tool body and chamfering section in the axial direction; a blade section and a guiding section are symmetrically formed between each chip discharge groove and the tool body end surface; a diamond material is embedded in the axial direction in the edge of each blade section to form a cutting edge; a diamond material is embedded between the chamfering section at the rear ends of the cutting edges and the corresponding chip discharge groove in the axial direction to form a chamfering edge. According to the integrally formed tool provided by the utility model, the chamfering section is formed in the rear end of the tool body, so that broaching and chamfering can be conducted in one process, the work efficiency is increased, the coaxialities of broaching and chamfering are consistent, and the machining quality is improved; the cutting edges and the chamfering edges are made of the diamond materials, so that the service life of the tool is effectively prolonged.
Description
Technical field
The utility model belongs to cutting tool technical field, specifically, is the one-body molded cutter of a kind of functions of reaming, chamfering.
Background technology
In machined field, often need to use forming cutter to mold members or part carries out smart reaming processing, after smart reaming completion of processing, re-use rose reamer and carry out chamfering.
Because traditional reaming and chamfering are divided into two procedures, its shortcoming is: 1, not only operating efficiency is low, and the axiality of chamfering is poor, has reduced crudy; 2, broad is generally Hardmetal materials, and service life is short, needs are frequent changes cutter, thereby greatly reduces operating efficiency.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of functions of reaming, chamfering simple in structure, that long service life is effectively increased work efficiency one-body molded cutter.
Scheme of the present utility model is achieved in that
The one-body molded cutter of a kind of functions of reaming, chamfering, 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, it is characterized in that: between described cutter hub and handle of a knife, one is shaped with a chamfering section, the outer rim of described cutter hub and chamfering section is axially 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 chamfering section of this cutting edge rear end and chip area, axially inlays the chamfering blades that a diamond is made.
And the length of described blade section is greater than the length of guide section.
And the one-body molded cutter of functions of reaming, chamfering according to claim 1 and 2, is characterized in that: 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:
This one-body molded cutter is by being shaped with chamfering section in the rear end of cutter hub, therefore can make functions of reaming, chamfering pass through a procedure processing, not only improve operating efficiency, and reaming is consistent with the axiality of chamfering, improve crudy, described cutting edge 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.
The one-body molded cutter of a kind of functions of reaming, chamfering, as shown in Figure 1, comprises handle of a knife 6 and cutter hub 3, and 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, between described cutter hub and handle of a knife, one is shaped with a chamfering section 5, the axial symmetry of outer rim of described cutter hub and chamfering section is shaped with two chip areas 2, between each chip area and cutter hub end face 7, form symmetrically arranged blade section A and guide section B, the cutting edge 1 that a diamond is made is all axially inlayed at described blade section edge, axially inlays the chamfering blades 4 that a diamond is made between the chamfering section of this cutting edge rear end and chip area.By being shaped with chamfering section in the rear end of cutter hub, therefore can make functions of reaming, chamfering pass through a procedure processing, not only improve operating efficiency, and reaming is consistent with the axiality of chamfering, improve crudy, described cutting edge and chamfering blades are diamond, have effectively improved the service life of cutter;
3,, in order to improve machining accuracy, the length of described blade section A is slightly larger than the length of guide section B;
4, 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.
5, described cutter hub end face is coaxially shaped with a locating hole 8, can fast forming cutter and preprocessing hole be positioned.
This one-body molded cutter is by being shaped with chamfering section in the rear end of cutter hub, therefore can make functions of reaming, chamfering pass through a procedure processing, not only improve operating efficiency, and reaming is consistent with the axiality of chamfering, improve crudy, described cutting edge 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.
