specific Embodiment 1

[0012] Specific embodiment 1, such as putting the shaped strips of precious metals, which are shaped like a lantern skeleton, into the grooves in the wax mold, and then clamp the strips of precious metals with a special pliers The head, so that all the heads are gathered together, and then spot-weld the two heads with a spot welding machine to form a lantern skeleton shape, and then put the wax mold into a high-temperature furnace to melt the wax mold to make a finished blank, and then match it with a point The components that make up the necklace are welded on and polished to complete the finished product.

specific Embodiment 2

[0013] Specific embodiment 2, put into the double-sided groove of solid wax mould, the head of each sheet precious metal is spot-welded with the head with spot welding machine as piece by piece precious metal, then laps with connecting sheet or connecting pipe Then connect them together by spot welding with a spot welding machine, and then lose wax at high temperature to make a cage-like semi-finished blank, which is also connected by component spot welding to form a chain. Such shapes can be varied, such as olive-shaped, spherical, gourd-shaped, and strip or sheet precious metals can also be in the form of filaments. Strip or flake precious metals are stamped and pressed in iron molds, and filamentary precious metals are made by drawing in iron molds, so the surface is smooth and shiny, and there is no need to use files for trimming, which avoids the loss of precious metals during the trimming process.

[0014] This technique is used in jewelry such as bracelets, necklaces, p...

Abstract

The invention relates to a jewelry processing technology, in particular to a new making technology of gold and silver jewelries. The making technology of gold and silver jewelries of the invention is characterized in that based on the traditional processing technology, after the procedure of injection of a wax mould, the new technology includes that a shaped stripped or flaky precious metal is fixed in the groove of the wax mould; both ends of the stripped or flaky precious metal are connected through the spot welding; the wax mould is then treated with the high-temperature lost-wax procedure in a high-temperature furnace to obtain a jewelry stock which is then set with a shaped component by the spot welding to be polished to obtain a finished product. The new technology of the invention can be applied to the production of jewelries such as oval or ball-shaped or gourd-shaped bracelets, necklaces, pendants and earrings and spares plaster molds and procedures of precious metal melting and reverse moulding, smashing plaster molds to obtain jewelry stocks and shaping with a rasper in the tradition technology so as to avoid the waste of precious metal, and also has the advantages of simple technology, reduction of the technology procedures and the making costs.

Description

technical field [0001] The invention relates to a jewelry processing technology, in particular to a new technology for making gold and silver jewelry and its application. Background technique [0002] In the past, the traditional gold and silver jewelry production process included the following steps: the sample silver plate was pressed out of the plastic mold in the laminating machine, and then the wax mold was injected in the wax injection machine, and then the wax mold was placed in gypsum powder, and the wax mold was heated by high temperature. Lose the wax to make a plaster mold, pour the molten precious metal into the plaster mold, when the precious metal is cooled in the plaster mold, break the plaster mold to take out the jewelry blank, then trim the jewelry blank with a file, and then Components of various shapes are inlaid and molded, then polished, and finally finished. The biggest defect of the traditional process is the large loss and cumbersome process, which ...
