Embodiment 1

[0042] Such as figure 1 As shown, the spectacle frame brazing equipment is used for the image 3 The welding position of the middle spectacle frame is welded, and the two spectacle frames 11 and the spectacle frame connecting beam 12 between the two spectacle frames 11 are brazed and fixed. The spectacle frame 11 and the spectacle frame connecting beam 12 are made of TC4 material, the solder is Ti51Zr27Cu15Ni, and the solder particle size is It is 200 mesh, the binder is polystyrene resin, and the ratio of solder and binder is 15:1.

[0043] The spectacle frame brazing equipment includes an integral housing 21 , a partition 22 and a conveying line 41 . The integral shell 21 is formed by a quartz tube. The partitions 22 at both ends of the quartz tube and the partition 22 in the axial middle divide the integral shell 21 into a first shell and a second shell 24. The first shell is the shell of the brazing area. twenty three.

[0044] A brazing space is formed inside the brazi...

Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, a second housing 24 is provided on the side of the brazing area housing 23 where the conveying line 41 enters, and a second housing 24 is provided inside the second housing 24. The heating device 32 is used to dry the creamy solder on the spectacle frame to be brazed and reduce the cooling rate of the weld seam after welding. In this embodiment, the heating device 32 is not provided in the second housing 24, and the second housing 24 is only used to form a gas buffer space to reduce the leakage of inert gas in the shell 23 of the brazing zone.

[0051] In addition, in other embodiments, the heating device 32 can also be used only for drying the creamy solder on the spectacle frame to be brazed, for example, it is only set on the upper side of the conveying plane corresponding to the conveying line 41, and only faces the upper side of the conveying line 41. The spectacle frame to be welded i...

Embodiment 3

[0053] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the conveying line 41 is a one-way circular rotating conveying line, while in this embodiment, the conveying line 41 is a forward and reverse reciprocating conveying line, and the conveying line 41 is forward and backward. The rotation will send the spectacle frame into the shell 23 in the brazing area, and the reverse rotation will transport the spectacle frame to the assembly area after the welding is completed. In addition, in the above-mentioned embodiments, the conveying line 41 has an upper and lower double-layer structure, and in other embodiments, the conveying line 41 may also have a single-layer structure.

Abstract

The invention relates to brazing of spectacle frames, in particular to a spectacle frame brazing device. The spectacle frame brazing device comprises a brazing area shell, a melting brazing device and a conveying line. A brazing space is formed in the brazing area shell, a gas inlet is formed in the brazing space, and the gas inlet is used for filling inert gas into the brazing space. The melting brazing device is arranged in the brazing space and used for heating the fed to-be-brazed spectacle frame so as to melt welding flux. The conveying line is provided with a spectacle frame assembling clamp, the spectacle frame assembling clamp is used for separately clamping and fixing all parts of the to-be-brazed spectacle frame, and the spectacle frame can be conveyed into and out of the brazing space when the conveying line runs. A conveying line avoiding opening is formed in the brazing area shell, the size of the conveying line avoiding opening corresponds to that of the conveying line, and the conveying line can enter the brazing space through the conveying line avoiding opening. By means of the scheme, automatic welding can be rapidly achieved, the welding uniformity is good, and generation of brittle compounds in the titanium alloy spectacle frame brazing process can be reduced through rapid heating under gas protection.

Description

technical field [0001] The invention relates to brazing of spectacle frames, in particular to brazing equipment for spectacle frames. Background technique [0002] At present, the decorative function of spectacle frames is getting stronger and stronger, the technical level is getting higher and higher, the material selection is getting more and more refined, and the market is developing more and more broadly. Titanium metal, as a new type of glasses material, has rapidly occupied the high-end glasses market due to its advantages of lightness, corrosion resistance, anti-allergy and high fatigue resistance, and is favored by more and more manufacturers. With the development of titanium materials and the increasing maturity of processing technology, many titanium-based frames, such as pure titanium and memory titanium, have appeared on the market. [0003] In the eyewear industry, brazing is the traditional method used to manufacture eyeglass frames, and its principle is to us...
