Description

Technical Field

[0001] This invention relates to the field of ear loop technology, specifically to a C-type ear loop processing technology. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. This allows you to listen to audio without disturbing others. They are commonly used in mobile phones, portable music players, radios, portable game consoles, and digital audio players.

[0003] For earbuds, the ear-hook design avoids inserting the earbuds directly into the ear canal, reducing pressure on the ears during prolonged wear and improving comfort. At the same time, this design allows the ears to breathe, reducing the risk of ear canal infections.

[0004] The ear hook cable of existing ear hook headphones is just a simple shaped steel wire. However, this structure has the following defects in actual manufacturing and use:

[0005] Solid, ordinary shaped steel wire is difficult to thread and inconvenient to coat with adhesive, thus reducing production efficiency and affecting aesthetics. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a C-type ear loop wire processing technology. The technical problem to be solved is that the ear loop wire produced by the existing ear loop wire manufacturing process has problems such as difficulty in threading and inconvenience in coating due to the use of ordinary shaped steel wire, resulting in low production efficiency.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a C-type ear loop processing technology, comprising the following steps:

[0008] S1: Flatten the round steel wire to obtain a rectangular steel sheet;

[0009] S2: The steel sheet is made into a steel pipe, and the cross section of the steel pipe along the perpendicular axis of the steel pipe is arc-shaped;

[0010] S3: Shape the steel pipe into a C-shape.

[0011] In one implementation, the process of flattening the steel wire in step S1 is as follows:

[0012] S10: Flatten the steel wire into the first steel sheet using a flattening machine;

[0013] S11: Anneal the first steel sheet in an annealing furnace;

[0014] S12: Flattening steel wire into a second steel sheet using a flattening machine;

[0015] S13: Anneal the second steel sheet in an annealing furnace;

[0016] S14: Flatten the steel wire into a third steel sheet using a flattening machine;

[0017] S15: Anneal the third steel sheet in an annealing furnace; the length of the cross-section of the third steel sheet is greater than the length of the cross-section of the second steel sheet, and the length of the cross-section of the second steel sheet is greater than the length of the cross-section of the first steel sheet; the width of the cross-section of the third steel sheet is less than the width of the cross-section of the second steel sheet, and the width of the cross-section of the second steel sheet is less than the width of the cross-section of the first steel sheet.

[0018] In one embodiment, in steps S10, S12 and S15, the speed of the flat wire machine is 5 m / min;

[0019] During annealing in steps S11, S13 and S15, the annealing rate of the steel sheet is 20 m / min, and an inert gas is used to protect the surface of the steel sheet.

[0020] In one embodiment, the process of making the steel sheet into a steel pipe in step S2 is as follows:

[0021] S20: The third steel sheet is drawn into an arc-shaped first profile using a tube drawing machine;

[0022] S21: Anneal the first profile;

[0023] S22: The first profile is drawn into a second profile in the shape of an arc using a tube drawing machine;

[0024] S23: Anneal the second profile; the diameter of the second profile is smaller than the diameter of the first profile.

[0025] In one embodiment, the pulling speed of the tube-pulling machine in steps S20 and S22 is 20 m / min, and the pulling force is 20 kg.

[0026] The annealing rate in steps S21 and S23 is 20 m / min, and an inert gas is used to protect the profile surface.

[0027] In one implementation, step S3 is as follows:

[0028] S30: Cut the second profile and place the cut-off second profile into the shaping mold;

[0029] S31: Place the shaping mold with the second profile into the muffle furnace for shaping.

[0030] In one embodiment, during the shaping process in the muffle furnace in step S31, the shaping temperature is 800°C and the shaping time is 25 minutes.

[0031] The beneficial effects of this invention compared with the prior art are: in actual use, the ear loop wire made by the process of this invention is C-shaped and has a threading channel, which facilitates threading, has a good adhesive effect, and is aesthetically pleasing.
