Embodiment 1

[0026] Such as figure 1 As shown in the figure, an automatic solderless welding technology for precious metal jewelry, including chain link production equipment with lifting lugs at both ends, the chain link production equipment includes a bead feeding device 1, a bead clamping device 2, a steering mechanism 3, and a wire feeding device 4 , a bending device 5 and a welding device 6, the welding device 6 includes a first welding torch 61 and a second welding torch 62, and the chain ring production equipment is a chain ring with hanging lugs at both ends disclosed in the Chinese invention patent application CN104015059A Equipment, no more details here; include the following steps:

[0027] (1) The bead feeding device 1 conveys the chain beads to the bead clamping device 2. The bead clamping device 2 clamps the chain beads, and then sends one end of the chain beads to the forming position. At the same time, the wire feeding device 4 conveys the material line and cuts off the fini...

Embodiment 2

[0039] This embodiment is basically the same as Embodiment 1, the difference is that the material of the chain beads and lifting lugs are all silver, during the welding process, the pressure of the first welding torch 61 and the second welding torch 62 is 1.4Mpa, and the preheating time is 1s, since the melting point of silver is 961°C, during the welding process, the flame temperature of the first welding torch 61 and the second welding torch 62 is 900°C-1000°C, preferably 1000°C in this embodiment.

Embodiment 3

[0041] This embodiment is basically the same as Embodiment 1, the difference is that the material of the chain beads and lifting lugs are all platinum, during the welding process, the pressure of the first welding gun 61 and the second welding gun 62 is 1Mpa, and the preheating time is 5s Since the melting point of platinum is 1769° C., the flame temperature of the first welding torch 61 and the second welding torch 62 is 1700° C. to 1800° C., preferably 1800° C. in this embodiment.

Abstract

The invention discloses an automatic solder-free welding technology for precious metal ornaments, and belongs to the technical field of jewelry processing devices. According to the automatic solder-free welding technology, a manufacturing device for chain rings with lifting lugs at two ends is included; firstly, chain balls and lifting lugs are conveyed to a forming position; then, melt welding is performed at the two portions of the joints of the lifting lugs and one end of one chain ball through a first welding gun and a second welding gun; then, the lifting lugs are conveyed to the forming position, meanwhile, the chain ball is driven by a steering mechanism to rotate by 180 degrees, then, melt welding is performed at one portion of the joints of the other end of the chain ball and the lifting lugs, automatic welding of one chain ring is completed, and so on, automatic welding of the multiple chain rings is completed. No any auxiliary solder needs to be added, the welding process is easy to control, the welding effect is good, the original product quality content is ensured, the structure is stable, the welding portion will never fade, and therefore the product is attractive.

Description

technical field [0001] The invention belongs to the technical field of jewelry processing equipment, and in particular relates to an automatic solderless welding technology for precious metal jewelry. Background technique [0002] Precious metal jewelry is more and more favored by consumers due to its small size and changeable shape, and the market demand is also increasing. For example, a single link of a necklace includes a bead and a bead welded to both ends of the bead. For half-ring lugs, usually only three of the four welding points are welded when making a chain link, and the remaining one welding point is welded when two adjacent chain links are connected in series. [0003] Chinese invention patent application CN104015059A discloses a chain ring manufacturing equipment with lifting lugs at both ends, which includes a frame; a bead feeding device for transporting chain beads downstream one by one; The chain beads are transported to the bead clamping device at the fo...
