The cutting speed is high, the processing smoothness is high, the outlet burrs are few, and the cost reduction and efficiency improvement are effectively realized for clients.
The technical scheme is as follows: in order to achieve the above purpose, the forming milling cutter for machining the motor rotor shell comprises a blade part, a neck part and a handle part, wherein the neck part is arranged at the middle position of the blade part and the handle part, a reinforcing part is arranged between the neck part and the handle part, five unequal designed blades are arranged on the blade part, chip grooves are arranged between adjacent blades, the spiral angle of each chip groove is 25 degrees, chip separation grooves are arranged on the back of each blade, a main oil hole is arranged on the handle part, five branch oil holes which are arranged in a dispersing mode are arranged on the blade part, and the main oil holes are communicated with the branch oil holes.
Further, the cutting edge is provided with a groove front angle of 6-10 degrees. The edge of the blade is passivated. The service life of the cutter is ensured while the cutting of the cutter is light and quick.
Further, the radius of the outer circular arc R of the reinforcing part is 5mm.
Further, a buried bolt is arranged at the center of the end face of the blade part. The purpose of the buried bolt design is to block the main oil hole and avoid the cooling water for the cutter from splashing out of the main oil hole.
Further, the lengths of the blade part, the neck part and the reinforcing part are sequentially reduced.
Further, the blade part, the neck part, the reinforcing part and the handle part are integrally formed and are made of hard alloy.
Further, the blade diameter of the blade portion is 12mm.
The technical scheme can be seen that the beneficial effects of the utility model are as follows:
the formed milling cutter for processing the motor rotor shell has the advantages that the cutting speed is high, the processing time of a customer is shortened to be half of that of the original one, the cost of a single part cutter is half of that of the original one, and the product qualification rate is high. The design of unequal 5-blade and the design of 25-degree spiral angle of the chip groove are adopted, so that the possibility of cutter vibration in the machining process of the milling cutter is reduced, the surface finish of the machined part is ensured, the outlet burrs are few, meanwhile, the blade part adopts 5 oil holes, the cooling of different positions of the blade part is realized, and the full cooling of the whole blade part is ensured.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a cross-sectional view of the present utility model.
Detailed Description
The utility model is further elucidated below in connection with the drawings and the specific embodiments.
The formed milling cutter for machining the motor rotor shell comprises a blade part 1, a neck part 3 and a handle part 2, wherein the neck part 3 is arranged at the middle position of the blade part 1 and the handle part 2, a reinforcing part 4 is arranged between the neck part 3 and the handle part 2, five blades 11 with unequal designs are arranged on the blade part 1, chip grooves 12 are arranged between the adjacent blades 11, the spiral angle of each chip groove 12 is 25 degrees, chip dividing grooves 7 are formed in the back of each blade 11, a main oil hole 5 is formed in the handle part 2, five branch oil holes 6 which are arranged in a dispersed mode are formed in the blade part 1, and the main oil holes 5 are communicated with the branch oil holes 6. The radius of the outer circular arc R of the reinforcing part 4 is 5mm. The lengths of the blade part, the neck part and the reinforcing part are sequentially reduced. The blade part 1, the neck part 3, the reinforcing part 4 and the handle part 2 are integrally formed and made of hard alloy. The whole cutter is made of hard alloy, so that the rigidity of the cutter is increased.
In this embodiment, the blade diameter of the blade portion 1 is 12mm. The existing 30mm blade diameter is reduced to 12, and meanwhile, the design of five-blade unequal and a spiral angle of 25 degrees is adopted, so that the possibility of cutter vibration in the machining process is reduced.
As shown in fig. 2, the blade 11 is provided with a groove rake angle of 6 ° to 10 °. The design can make the cutter cutting lighter and faster, and prolong the service life of the cutter.
In this embodiment, a buried bolt 13 is provided at the center of the end face of the blade 1. The buried plug 13 is attached to the end surface of the blade portion 1 to block the main oil hole 5, and can prevent the cooling water from splashing out of the main oil hole 5 of the tool.
The examples are intended to illustrate the utility model and not to limit its scope, and after reading the utility model, various equivalents of the utility model by those skilled in the art are within the scope of the utility model as defined by the appended claims.
