Description
Technical field
The utility model belongs to chip cutting-tool engineering field, relates to a kind of composite step drill bit integrating boring, fraising, chamfering.
Background technology
Step drill is widely used in the processing of thin plate, thin-wall hole, the drill bit that step drill is made up of the one group of brill of the different-diameter by certain designing requirement rank, the thin plate machining hole different to one group of aperture and chamfering, without the need to changing the drill bit of different-diameter, substantially increase production efficiency.But step drill is in the market all make with doing material at a high speed, and easily wear and tear, drilling life of bit is short, and can not process fraising simultaneously.
Therefore, how solving the problem, is the content that the utility model will be studied.
Summary of the invention
For overcoming above-mentioned deficiency of the prior art, the utility model object is to provide a kind of composite step drill bit integrating boring, fraising, chamfering.
For achieving the above object and other relevant objects, the utility model provides a kind of composite step drill bit integrating boring, fraising, chamfering, comprises knife bar; One end extension of described knife bar is provided with processing department, and the head of described processing department is boring blade, and the middle part of described processing department is fraising blade, and the afterbody of described processing department is chamfer machining blade; Described knife bar and processing department one-body molded; Described boring blade, fraising blade and chamfer machining blade are also one-body molded.
In such scheme, related content is explained as follows:
1, in such scheme, described processing department is from head bore cutter sword, middle part fraising blade and afterbody chamfer machining blade tapered structure successively;
2, in such scheme, described knife bar and processing department one-body molded by tungsten steel bar.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, the utility model structure is simple, is easy to realize.Collection boring fraising chamfering three functions are structure as a whole.Above-mentioned three kinds of operations can be completed simultaneously, in process, save tool change time, reduce the processing cost to hole;
2, composite step drill bit of the present utility model, overturn the way of conventional knife, dedicated tool software is adopted to optimize geometric angle by computer accurate Calculation, the simulation of 3D cutter is first realized by the special-purpose software of computer, then retrofit is carried out by special-purpose software on the high-accuracy five-shaft numerical control grinding machine of program importing import Germany of simulating carefully, for client improves production efficiency, reduce production cost and accelerate productive temp, also meet the low-carbon energy-saving environmental protection concept advocated at present;
3, composite step drill bit of the present utility model, select German import high-tensile (3900 Ns/square millimeter) tungsten steel bar, it is nano particle (0.6 nanometer) and other rare metals that this bar has high rigidity (HRA93.6) high red hardness (1000 DEG C) tungsten carbide, still can normally work under the severe cutting state of high-speed and high-temperature.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, a kind of composite step drill bit integrating boring, fraising, chamfering, comprises knife bar 1; One end extension of described knife bar 1 is provided with processing department 2, and the head of described processing department 2 is boring blade 21, and the middle part of described processing department 2 is fraising blade 22, and the afterbody of described processing department 2 is chamfer machining blade 23; Described knife bar 1 is one-body molded with processing department 2; Described boring blade 21, fraising blade 22 and chamfer machining blade 23 are also one-body molded.
Described processing department 2 is from head bore cutter sword 21, middle part fraising blade 22 and afterbody chamfer machining blade 23 tapered structure successively.
Described knife bar 1 and processing department 1 one-body molded by tungsten steel bar.
During work, first holed by boring sword, and carry out fine finishining process by fraising blade, finally undertaken by chamfering processing aperture.This product integrates boring fraising chamfering three functions, can complete above-mentioned three kinds of operations simultaneously, save tool change time, reduce the processing cost to hole in process.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
