Embodiment 1

[0032] This embodiment is a basic embodiment of the present invention. The main material of the spectacle frame to be welded is silver. It discloses a low-temperature welding method for spectacle frames. It should be noted that the spectacle frame described in this embodiment uses silver as the main material. , which includes the following steps:

[0033] A. Clamp the spectacle accessories that have been processed in the early stage such as grinding and polishing to the corresponding position on the special mold, and adjust the position of the spectacle accessories so that the position between each spectacle accessory is in the best welding position;

[0034] B. Turn on the shielding gas delivery device and continuously feed pure argon gas into the welding area as shielding gas, so as to isolate the air in the welding area and form a protective layer for the welding area;

[0035] C. After 3 seconds of starting to deliver the shielding gas, send the silver welding wire with a ...

Embodiment 2

[0040] This embodiment, as another preferred embodiment of the present invention, discloses a low-temperature welding method for spectacle frames. It should be pointed out that the spectacle frame described in this embodiment is made of silver as the main material, and the welding method includes the following steps :

[0041] A. Clamp the spectacle accessories that have been processed in the early stage such as grinding and polishing to the corresponding position on the special mold, and adjust the position of the spectacle accessories so that the position between each spectacle accessory is in the best welding position;

[0042] B. Turn on the shielding gas delivery device and continuously feed pure helium gas into the welding area as shielding gas, so as to isolate the air in the welding area and form a protective layer for the welding area;

[0043] C. After 4 seconds of starting to deliver the shielding gas, the tin-based welding wire with a diameter of 0.5mm is delivered...

Embodiment 3

[0048] This embodiment, as another preferred embodiment of the present invention, discloses a low-temperature welding method for spectacle frames. It should be pointed out that the spectacle frame described in this embodiment is made of silver as the main material, and the welding method includes the following steps :

[0049] A. Clamp the spectacle accessories that have been processed in the early stage such as grinding and polishing to the corresponding position on the special mold, and adjust the position of the spectacle accessories so that the position between each spectacle accessory is in the best welding position;

[0050] B. Turn on the shielding gas delivery device and continuously feed the mixed gas of argon and hydrogen into the welding area as the shielding gas. According to the actual production conditions such as the activity of the welding wire and the main material, and the reaction temperature, it is determined that the argon gas accounts for 85% of the total ...

Abstract

The invention discloses a low-temperature welding method for silver or aluminum spectacle frames. Firstly, the invention utilizes the characteristic of instantaneous high temperature during welding to reduce the adverse effect of high temperature on silver or aluminum materials, thereby completing the welding area of ​​the spectacle frame. Carry out one-time structural welding, and then solder soldering with good capillary action to perform secondary welding and weld beautification treatment on the welding area, thus overcoming the defects of traditional welding technology welding silver or aluminum products, which not only reduces the silver or aluminum The welding difficulty of making spectacle frames has improved the welding quality and efficiency of silver or aluminum spectacle frames; it is conducive to the large-scale promotion of spectacle frames with silver or aluminum as the main material.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a low-temperature welding method for spectacle frames. Background technique [0002] At present, spectacles have been widely used as a kind of important vision correction device, including rimmed spectacles, half-rimmed spectacles and rimless spectacles. If the glasses are worn on the bridge of the nose for a long time, if the glasses are made of welded metal frames, the weight will be too large, which will cause greater pressure on the bridge of the nose during long-term wearing, which will not only affect the comfort of wearing the glasses, but also damage the bridge of the nose. Therefore, in order to improve the comfort of metal frame glasses, it is necessary to reduce the weight of glasses as much as possible; aluminum is widely used in industry as a material that is lighter than titanium, but because aluminum itself is soft and has good The thermal conductivit...
