Embodiment Construction

[0023] The invention will now be described with reference to the accompanying drawings. like figure 1 Shown is the structural representation of an embodiment of the dagger drill of the present invention. The dagger drill includes a first section 1, a middle section 2 and a tail section 3, wherein the middle section 2 connects the first section 1 and the tail section 3, that is, the dagger drill is a continuous forming member.

[0024] More specifically, a continuous cutting edge 4 is provided around the axis direction L of the dagger drill from the first section 1 , the middle section 2 to the tail section 3 . That is to say, the blade 4 extends continuously on the above-mentioned three sections, and is arranged around the axis direction L of the dagger drill, so as to form figure 1 In the helically extended shape shown, drilling cutting is performed with the cutting edge 4 of this shape.

[0025] In addition, the end of the first section 1 can be configured as a tip 11 , a...

Abstract

The invention provides a dagger drill on one hand. The dagger drill comprises a head segment (1), a tail segment (3), and a middle segment (2) for connecting the head segment (1) and the tail segment (3). A continuous blade (4) is arranged around an axis direction (L) of the dagger drill from the head segment (1), the middle segment (2) to the tail segment (3); the end head of the head segment (1) forms a tip (11); and the diameter of the blade (4) is gradually increased from the first segment (1) to the middle segment (2). The invention also provides a method for hole processing on the other hand. According to the dagger drill and the method for hole processing provided by the invention, the improvement of the processing efficiency, the reduction of the layering risk of hole processing, and the improvement of the quality of a hole can be realized at least.

Description

technical field [0001] The present invention relates to a process for hole machining of composite materials, and more particularly, to a dagger drill and a method for hole machining. Background technique [0002] Due to its small specific gravity, high specific strength and specific modulus, carbon fiber composite materials also have excellent chemical stability, wear reduction, fatigue resistance, creep resistance, noise reduction, electrical insulation and other properties, so they are widely used in the aerospace field. more and more applications. [0003] After the carbon fiber composite parts are formed, hole processing is required for assembly with other parts. However, due to the characteristics of high strength, high hardness, poor thermal conductivity, brittleness, and low interlayer strength of carbon fiber composite materials, hole processing will produce defects such as delamination and tearing, especially when drilling holes by hand, and the quality of the hole...
