Description
Technical Field
The utility model belongs to but transposition milling cutter field especially relates to a take rough skin milling cutter of chip groove spiral milling cutter piece.
Background
The rough milling cutter is also called as an indexable spiral end milling cutter, the surface of the rough milling cutter is in a dense spiral reticulate pattern shape, the groove is shallow, and the rough milling cutter is generally used in the machining field with large machining allowance and low machining surface requirement. The cutting edge is composed of a plurality of cutting units, and the cutting edge is sharp, so that the cutting resistance is greatly reduced, high-speed cutting can be realized, the effect of replacing grinding with milling is achieved, and the service life of the milling cutter is prolonged.
The indexable helical end mill is suitable for large deep hole machining, while the helical edge mill is suitable for various face milling, side milling and complex profiling milling. However, the conventional indexable helical end mill often has the following problems in the process of heavy cutting in practical use:
1. the vibration problem is as follows: the traditional indexable spiral end mill generates larger vibration when the blade is contacted with a workpiece due to unbalanced stress, so that the processing effect is influenced
2. The load problem is as follows: indexable helical end mills are often used for machining workpieces with large machining margins, so that in the actual machining process, in order to reduce the machining time, the depth of cut of the milling cutter is large, and the load borne by the cutter is large.
3. The problem of the discharge amount of the iron chips: the indexable spiral end mill is used for machining workpieces with large machining allowance, so that the machined scrap iron is larger than the scrap iron produced by finish machining, the scrap removal is difficult to occur, and the resistance is increased.
4. Noise problem: the indexable spiral end mill has the problems that the load is large, scrap iron is not easy to discharge and the like due to the vibration of the indexable spiral end mill, and the like, so that large noise is generated during machining.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art exists not enough, has solved the big and big problem of iron fillings granule of current transposition spiral milling cutter piece vibration, load, milling cutter piece noise, and aims at providing a thick skin milling cutter of taking chip groove spiral milling cutter piece, the utility model discloses a but transposition spiral end mill can effectively restrain the vibration, and the noise reduction can reduce iron fillings granule size simultaneously.
In order to solve the technical problem, the utility model discloses a technical scheme does: the rough skin milling cutter with the chip dividing groove spiral milling blade is provided with at least four spiral grooves, a chip dividing groove spiral milling blade is arranged in each spiral groove, each chip dividing groove spiral milling blade comprises a blade body, and at least one chip dividing groove is formed in the working surface of each blade body; the number of chip separating grooves formed on the working surface of the milling blade with the same spiral groove is the same.
The chip dividing grooves are U-shaped, semicircular or triangular.
The number of the chip separating grooves on each working surface is one, two or three.
To the problem that current milling cutter piece exists, compared with the prior art, the utility model following beneficial effect has.
First, the vibration problem is mainly aroused by the atress is unbalanced, and how the blade makes the adsorptivity better when contacting with the work piece, moves more stably, grabs the ground like automobile tire, has very big inspiration to how the blade moves, the utility model discloses a designed the chip groove, solved this problem, made course of working radial steady, the suppression vibration.
Secondly, the milling cutter has large load when cutting at large depth, and the milling cutter blade can manufacture a plurality of cutter angles by designing a chip dividing groove, thereby increasing the length and sharpness of the cutting edge, reducing the axial resistance, enabling large cutting depth and high feeding to be possible, and simultaneously improving the linear speed to more than 50%.
Thirdly, the chip dividing groove milling cutter blade is used for decomposing chips into fine chips or particles to play a role in chip dividing; meanwhile, the discharge amount of the chips per unit time is increased and is more than one time of the traditional discharge amount.
Fourthly, the milling cutter blade of the chip dividing groove reduces the axial load, the radial processing is stable, the vibration is reduced, and the noise is greatly reduced.

Detailed Description
As shown in fig. 1-3, the spiral milling insert with separated flutes comprises an insert body 1, and at least one separated flute 2 is formed on the working surface of the insert body 1. The shape of the chip dividing groove 2 can be selected according to the actual use condition and the manufacturing process, and the chip dividing groove can be U-shaped, semicircular or triangular. The number of the chip separating grooves 2 on each working surface is one, two or three. The recommended use is a one-edge or two-edge design (one or two chip separating grooves 2), which is the most common model, and the structural design mainly considers the balance design of the strength, the sharpness, the scrap iron treatment and the like of the blade.
As shown in fig. 4-5, another technical solution protected by the present invention is: rough skin milling cutter has four at least helicla flutes, adopts in its helicla flute the utility model discloses a divide grooving spiral milling cutter piece, the chip groove 2 quantity of dividing that the milling cutter piece working face of same helicla flute was seted up is the same.
As shown in fig. 4, the first and fourth spiral grooves are provided with a double-edged blade, the second and third spiral grooves are provided with a single-edged blade, as shown in fig. 5, the first and second spiral grooves are provided with a double-edged blade, and the third and fourth spiral grooves are provided with a single-edged blade, which can balance the cutting force and chip separation treatment of the blades. In particular, different milling cutters can be provided with different chip separation grooves 2 and different arrangement sequences, which mainly considers the overlapping effect of the blades in the actual use process.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
