Description

Technical Field

[0001] The utility model relates to the technical field of milling reverse buckle tools, in particular to a reinforced milling reverse buckle tool. Background Art

[0002] With the improvement of domestic processing technology, a large number of foreign aviation product parts have flooded in, and some products with higher appearance requirements have gradually increased. For the reverse buckle processing that traditionally requires two processes of turning over, its surface finish can no longer meet the customer's requirements, and some surfaces cannot even be polished. Therefore, the application of T-shaped milling reverse buckle tools has been gradually promoted. However, due to the limitation of the thickness of the raw material, the thickness of traditional milling reverse buckle tools is generally thin, resulting in insufficient rigidity, less cutting depth during processing, and low processing efficiency.

[0003] Therefore, the technical personnel in this field are committed to developing a reinforced milling reverse buckle tool to increase the tool strength, improve production efficiency, and save processing costs. Summary of the Utility Model

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is the insufficient rigidity of the tool, less cutting depth during processing, and low processing efficiency.

[0005] To achieve the above object, the utility model provides a reinforced milling reverse buckle tool, including a tool shank part, a connecting part, and a cutting edge part. The tool shank part, the connecting part, and the cutting edge part are coaxially arranged. The tool shank part is connected to the cutting edge part through the connecting part. The cutting edge part and the tool shank part are arranged in a T shape. The connecting part has an inclined surface with an inverted C angle between the tool shank part and the cutting edge part.

[0006] Further, the tool shank part is in the shape of a cylinder.

[0007] Further, the cutting edge part is in the shape of a disc.

[0008] Further, the connecting part is in the shape of a frustum of a cone.

[0009] Further, the diameter of the cutting edge part is larger than the diameter of the tool shank part.

[0010] Further, one end of the connecting part is in arc transition with the tool shank part.

[0011] Further, the other end of the connecting part is in arc transition with the cutting edge part.

[0012] Further, the angle between the inclined surface of the connecting part and the disc surface of the cutting edge part is between 30° and 60°.

[0013] Further, the tool shank part, the connecting part, and the cutting edge part are integrally formed.

[0014] Further, the cutting edge of the cutting blade portion is provided on the outer edge of the disc shape.

[0015] Advantages of the present utility model:

[0016] Based on the traditional milling undercut tool, the present utility model innovatively extends a certain C angle from the handle portion, increasing the rigidity of the cutting blade. This design significantly enhances the strength of the tool, doubles or more the cutting speed and the depth of cut, and ultimately makes the surface finish of the product more beautiful.

[0017] The following will further illustrate the concept, specific structure and technical effects of the present utility model in conjunction with the accompanying drawings to fully understand the purpose, features and effects of the present utility model. Description of the drawings

[0023] The following introduces the preferred embodiments of the present utility model with reference to the accompanying drawings of the specification to make its technical content clearer and easier to understand. The present utility model can be embodied in many different forms of embodiments, and the protection scope of the present utility model is not limited to the embodiments mentioned in the text.

[0024] In the drawings, components with the same structure are denoted by the same reference numerals, and components with similar structures or functions everywhere are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present utility model does not limit the size and thickness of each component. To make the drawings clearer, the thickness of some parts in the drawings is appropriately exaggerated.

[0025] The present utility model relates to an undercut surface that cannot be formed in one process, and this undercut surface requires high surface finish and cannot be polished. By applying the enhanced milling undercut tool for processing, not only the production efficiency is improved, but also the processing cost is saved.

[0026] Such asFigure 1 As shown, the traditional milling undercut tool 1 is a T-shaped milling undercut tool,

[0027] As the undercut size of the product part 2 increases, the diameter of the traditional milling undercut tool 1 also increases accordingly, but its rigidity decreases, resulting in a reduction in the depth of cut and feed rate, thereby affecting the machining efficiency.

[0028] Such as Figure 2 As shown, the enhanced milling undercut tool 3 of the present utility model is innovated on the basis of the traditional milling undercut tool 1. In the design, a certain C angle is extended at the handle part, thereby enhancing the rigidity of the cutting edge part. This design significantly enhances the strength of the enhanced milling undercut tool 3, doubles the cutting speed and the depth of cut, and finally makes the surface finish of the product part 2 more beautiful.

[0029] The present utility model aims to solve technical problems such as insufficient tool rigidity, small depth of cut during machining, and low machining efficiency. To this end, the present utility model adopts the following technical solutions to address these challenges:

[0030] In the machining of aerospace product parts, the surface finish and the smoothness of the appearance of the arc structure and the undercut structure are crucial, especially in the decorative parts visible to the naked eye. Therefore, it is necessary to use a T-shaped milling undercut tool for machining. By enhancing the strength of the tool, the service life and machining efficiency of the tool can be significantly improved.

[0031] Embodiment

[0032] Such as Figures 3 - 4 As shown, this embodiment provides an enhanced milling undercut tool 3, including a handle part 4, a connecting part 5, and a cutting edge part 6. The handle part 4, the connecting part 5, and the cutting edge part 6 are coaxially arranged. The handle part 4 is connected to the cutting edge part 6 through the connecting part 5. The cutting edge part 6 and the handle part 4 are arranged in a T shape. The connecting part 5 has an inclined surface with an inverted C angle between the handle part 4 and the cutting edge part 6.

[0033] Preferably, the handle part 4 is in the shape of a cylinder, the cutting edge part 6 is in the shape of a disc, and the connecting part 5 is in the shape of a frustum of a cone.

[0034] The diameter of the cutting edge part 6 is larger than the diameter of the handle part 4.

[0035] Wherein, one end of the connecting part 5 is in arc transition with the handle part 4, and the other end of the connecting part 5 is in arc transition with the cutting edge part 6.

[0036] Preferably, the angle between the inclined surface of the connecting part 5 and the disc surface of the cutting edge part 6 is between 30° and 60°.

[0037] In this embodiment, the handle part 4, the connecting part 5, and the cutting edge part 6 are integrally formed.

[0038] The cutting edge of the cutting edge portion 6 is provided on the outer edge of the disc shape.

[0039] Compared with the traditional milling undercut tool, the utility model adds a C angle in the tool design and performs an arc treatment on the corner position. This design further enhances the strength of the tool, and at the same time, the increase in the undercut size makes the application of this type of tool more extensive.

[0040] Due to the strengthened milling undercut tool 3 having a strengthened C angle, the cutting depth and feed rate of the strengthened milling undercut tool 3 can be increased, so as to ensure that the machine tool can operate at a high speed, greatly improving the processing efficiency.
