The part usually needs to chamfer its groove or limit of processing, because the chamfer angle that relates to is different, need change the chamfer milling cutter of different specifications, can cause operating personnel like this to need prepare multiple chamfer milling cutter, and it is inconvenient to use, and it is long when having increased the cost and having processed.
SUMMERY OF THE UTILITY MODEL
The utility model solves the problems that: the central multi-angle chamfering machining efficiency of the prior art is low, and a double-chamfer milling cutter is provided.
The double-chamfer milling cutter comprises a cutter handle part and a milling part, wherein the milling part is provided with a first cutter edge part, a second cutter edge part and chip grooves, the cutter handle part, the milling part, the first cutter edge part and the second cutter edge part are integrally formed, the chip grooves are symmetrically arranged, the chip grooves are straight grooves, the first cutter edge part and the second cutter edge part are arranged at the intersection of the chip grooves and the outer surface of the milling part, fixed included angles are formed between the first cutter edge part and the second cutter edge part and the cutter handle part, and the first cutter edge part and the second cutter edge part are two sections of continuous cutting edges from the top of the milling part to the side surface of the milling part.
Furthermore, the double-chamfer milling cutter is made of fine-grain pure tungsten-cobalt hard alloy without a coating.
Further, the diameter of the handle part is 8 mm.
Further, the included angle between the first blade part and the handle part is 45 degrees, and the length of the first blade part along the handle part is 2 mm.
Further, the included angle between the second blade part and the handle part is 12 degrees, and the length of the second blade part along the direction of the handle part is 4 mm.
The utility model has the beneficial effects that:
by adopting the structure, the double-chamfer milling cutter can be suitable for chamfering processing at two different angles by selecting different blade parts to be contacted with a workpiece, and has the advantages of simple and reasonable structure and convenient operation.
Drawings
FIG. 1 is a front view of a double chamfer milling cutter according to the present invention;
fig. 2 is a left side view of a double chamfer milling cutter according to the present invention.
In the figure: 1, a tool handle part; 2, a milling part; 3 a first blade part; 4 a second blade portion; 5 chip grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-2, the present invention provides a double chamfer milling cutter, which includes a handle portion 1 and a milling portion 2, wherein the milling portion 2 is provided with a first cutting edge portion 3, a second cutting edge portion 4 and a chip discharge groove 5, the handle portion 1, the milling portion 2, the first cutting edge portion 3 and the second cutting edge portion 4 are integrally formed, the chip discharge groove 5 is symmetrically provided with two chip discharge grooves, the chip discharge groove 5 is a straight groove, the first cutting edge portion 3 and the second cutting edge portion 4 are located at the intersection of the chip discharge groove 5 and the outer surface of the milling portion 2, the first cutting edge portion 3 and the second cutting edge portion 4 both form a fixed included angle with the handle portion 1, and the first cutting edge portion 3 and the second cutting edge portion 54 are two consecutive cutting edges from the top of the milling portion 2 to the side of the milling portion 2.
In practical application, the double-chamfer milling cutter is mainly used for processing aluminum parts, and the double-chamfer milling cutter is made of fine-grain pure tungsten-cobalt hard alloy without a coating and has the characteristics of aluminum processing; the material is soft, but is relatively sticky, and is easy to generate scraps and tumors compared with other materials such as steel parts. Therefore, the processing of aluminum alloy has special requirements, and the fine-grained pure tungsten-cobalt hard alloy is generally adopted without a coating. The cutting edge is sharp and the surface is ground, so that a lower friction coefficient is achieved, and generation of accumulated scraps is reduced.
In practical application, the diameter of the tool shank part 1 is 8 mm.
In practical application, an included angle between the first blade part 3 and the handle part 1 is 45 °, and the length of the first blade part 3 along the handle part 1 direction is 2 mm.
In practical application, the included angle between the second blade portion 54 and the shank portion 1 is 12 °, and the length of the second blade portion 4 along the shank portion 1 direction is 4 mm.
The working principle of the utility model is as follows:
the double-chamfer milling cutter can be suitable for chamfering at two different angles, and is simple and reasonable in structure and convenient to operate.
In conclusion, the double-chamfer milling cutter can be used for machining and forming an end face, an end face groove and a chamfer in three working procedures at one time, and has the advantages of high machining precision and high machining efficiency.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the foregoing embodiments are merely illustrative of the technical spirit and features of the present invention, and the present invention is not limited thereto but may be implemented by those skilled in the art.
