Problems solved by technology

However, the traditional processing technology uses a spherical drill to drill holes. The spherical drill is not a cutting material but a high-speed rotating grinding material on the soft soft ear mold. Therefore, on the one hand, the high temperature of the grinding can easily cause the drill to burn black, causing the drill to be used several times. It is scrapped due to annealing, resulting in increased cost; on the other hand, when drilling, the soft ear mold is not easy to locate due to its own characteristics, and it can only be pinched by fingers, and at the same time, the spherical drill inevitably shakes and shakes, so drilling not only The deviation is large, the scrap rate is high, and the hand is easily injured, which poses a safety hazard
Moreover, this kind of drilling tool not only causes a large deviation of the tube hole, which affects the fixing of the sound tube, but also causes the roughness of the hole wall, causing a large amount of powdery fine particles to adhere to the hole wall. A layer of sand, after the sound tube is inserted, it is easy to slip or even slip out of the hole and fall off
In view of the above reasons, it takes 4-5 minutes for skilled workers to process a qualified soft ear mold hole, which is very inefficient.

Embodiment 1

[0026] Such as Figure 1-4 As shown, a soft ear mold punching tool includes a longitudinal cutting part 22 and a handle 24 at one end of the cutting part 22 for grasping. The cutting part 22 is a rigid straight pipe with a wall thickness of 0.5-1mm, and a material ejection hole 222 is provided on one side of the cutting part 22 .

[0027] Specifically, the cutting part 22 is made of stainless steel, which is hard and durable. A pipe wall thickness of 0.5-1 mm can maintain a good cutting force on the soft ear mold 4 and reduce resistance. The axial length L1 of the cutting part 22 is 31.9mm, and the axial length L2 of the shank 24 is 52.5mm, so that the ratio of the latter to the former is 5.25:3.19-6.86:3.66, which is in line with the comfort of the human hand and is easy to use force , the cutting portion 22 has a suitable length for forming the soft ear mold 4 at one time, and the strength is also guaranteed. In this embodiment, the shank 24 is cylindrical, and the diamet...

Embodiment 2

[0030] Such as Figure 1-4 As shown, a soft ear mold punching tool differs from Embodiment 1 in that: the wall thickness of the cutting part 22 is 0.5-1 mm, the axial length L1 of the cutting part 22 is 36.6 mm, and the axial length L2 of the handle 24 It is 68.6mm. The diameter D2 of the shank portion 24 is 8.3 mm, and the outer diameter D1 of the cutting portion 22 is 2.4 mm. The distance L3 between the stripping hole 222 and the end of the cutting portion 22 away from the shank 24 is 16.7 mm, the length L of the stripping hole 222 along the axial direction of the cutting portion 22 is 4.3 mm, the width d is 1.6 mm, and the depth h is 0.2 mm.

[0031] Punching tools of this size are more suitable for, but not limited to, punching soft ear molds for children.

[0032] The following describes the method for punching holes using the soft ear mold punching tool of the present invention including the above-mentioned embodiments 1-2: fix the soft ear mold 4 and drill the cutting...

Abstract

The invention discloses a soft ear die punching tool which is characterized by comprising a longitudinal cutting part and a handle part, wherein the handle part is positioned at one end of the cutting part and is used for being held; the cutting part is a rigid straight pipe; the pipe wall has a thickness of 0.5 to 1mm; one side of the cutting part is also provided with a returning hole. The soft ear die punching tool breaks through a conventional electric drilling manner, adopts a simple structure of the rigid straight pipe and the returning hole, changes a grinding manner into a cutting manner and dose not consume a ball milling drill bit; not only is energy consumption reduced, the soft ear die punching tool is safe to use and the service life of the tool can be greatly prolonged, but also the surface of an obtained pore path is smooth, processing accuracy is high, and a sonic tube is tightly joined after being inserted and embedded into the pore path and is avoided falling down due to slippage. Furthermore, processing efficiency can be improved and one pore path can be completed in more than ten seconds from original time of 4 to 5 minutes consumed when an electric drill is used.

Description

technical field [0001] The invention relates to a drilling tool. Background technique [0002] With the development of technology, the earplugs of behind-the-ear hearing aids have developed to the stage of customization according to the shape of the individual ear canal, because the soft ear mold customized according to the shape of the ear canal can fit closely with the side wall of the ear canal, which can better play the role of hearing aids. Hearing effect. In the preparation process of behind-the-ear hearing aids, soft ear molds need to be drilled through holes, and the formed holes have a certain curvature to connect the sound tube. However, the traditional processing technology uses a spherical drill to drill holes. The spherical drill is not a cutting material but a high-speed rotating grinding material on the soft soft ear mold. Therefore, on the one hand, the high temperature of the grinding can easily cause the drill to burn black, causing the drill to be used se...
