Description

A high-gloss chamfering milling cutter

technical field

The utility model relates to the technical field of cutting tools, in particular to a high-gloss chamfering milling cutter.

Background technique

In order to remove the burrs produced by machining on the parts and to facilitate the assembly of the parts, chamfers are generally made on the ends of the parts. Chamfering has become an essential and important process in machining.

As people's requirements for product appearance quality are getting higher and higher, a good high-gloss chamfering effect has become an important criterion for measuring product appearance quality. However, the existing chamfering treatment is generally done with ordinary milling cutters, which cannot achieve a high-gloss effect and has low cutting efficiency.

Therefore, it is necessary to develop a milling cutter that has a simple structure and can achieve a high-gloss chamfering effect.

Utility model content

The purpose of the utility model is to provide a high-gloss chamfering milling cutter, which has a simple structure, can realize high-gloss chamfering, and has high cutting efficiency.

For this purpose, the utility model adopts the following technical solutions:

A high-gloss chamfering milling cutter, including a handle and a cutter head; the cutter head includes a cutter head connecting portion connected to the handle and a knife connected to the end of the connecting portion of the cutter head away from the handle The head cutting portion; the cutting portion of the cutter head includes a cutting edge arranged obliquely, and a rake face and a flank face intersecting to form the cutting edge, and the flank face is sequentially provided with a first relief angle from the cutting edge and a second relief angle, and the first relief angle is 1°-3°, and the second relief angle is 12°-18°.

Further, the inclination angle of the cutting edge is 45°.

Further, the first relief angle is 2°, and the second relief angle is 15°.

Further, the width of the first relief angle is 0.2mm-0.4mm.

Further, a chamfer with a width of 0.3 mm to 0.5 mm is provided at the edge of the connecting part of the cutter head.

Further, the length ratio of the cutter head to the cutter handle is 1:1.4-2.

Further, the length ratio of the cutter head cutting part to the cutter head connecting part is 1:1.5-2.5.

The beneficial effects of the utility model are: the high-gloss chamfer milling cutter of the utility model has a simple structure, can realize high-gloss chamfer processing, and has high cutting efficiency.

Description of drawings

Fig. 1 is a structural schematic diagram of a high-gloss chamfering milling cutter provided by the utility model.

In the figure: tool handle 10; cutter head 20; cutter head connecting portion 30; cutter head cutting portion 40; rake face 41; flank face 42; cutting edge 43.

Detailed ways

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

As shown in Figure 1, a high-gloss chamfering milling cutter includes a handle 10 and a cutter head 20; The cutter head cutting part 40 at one end of 10; There are a first rear angle and a second rear angle, and the first rear angle is 1°-3°, and the second rear angle is 12°-18°.

The high light chamfering milling cutter of the present utility model, by arranging the cutter head connection part 30 between the handle 10 and the cutter head cutting part 40, to improve the overall structural strength of the high light chamfering milling cutter; The cutting edge 43 realizes the high-gloss chamfering treatment of the product to be cut, and has a simple structure and high cutting efficiency.

Specifically, the inclination angle of the cutting edge 43 relative to the central axis direction of the tool handle 10 is 45°, so that the cutting edge 43 can apply a uniform cutting force to the contact surface of the product to be cut, and not only can realize the high-gloss chamfering of the product to be cut processing, and can reduce the wear of the cutting edge 43 and prolong the service life of the high-gloss chamfer milling cutter.

In order to ensure that the cutting edge 43 has sufficient strength, the width of the first relief angle can be set to 0.2mm-0.4mm.

In the high-gloss chamfer milling cutter, the first relief angle is mainly used to squeeze light, while the second relief angle is mainly used to avoid the product to be cut. Wherein, the angle of the second relief angle should not be too large, so as not to reduce the rigidity of the cutting edge 43 . As a preferred embodiment of the present invention, the first relief angle is 2°, and the second relief angle is 15°.

In order to ensure the overall structural strength of the high-gloss chamfer milling cutter, the length ratio of the cutter head 20 to the cutter handle 10 is 1:1.4-2. The length ratio of the cutter head cutting portion 40 to the cutter head connecting portion 30 is 1:1.5˜2.5.

In addition, chamfers with a width of 0.3 mm to 0.5 mm are provided at the edges of the cutter head connecting portion 30 to avoid cutting hands during the use of the high-gloss chamfer milling cutter.

The technical principles of the present utility model have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the utility model, and cannot be construed as limiting the protection scope of the utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific implementations of the present utility model without creative work, and these forms will all fall within the protection scope of the present utility model.
