Welding-free embedded noble metal ornament sealing method

Abstract

The present invention provides a welding-free embedded noble metal ornament sealing method, wherein servo type hydraulic or stamping equipment is adopted to produce one or more than one main bodies, and then assembling molds are adopted to carry out fixation or sealing connection of top connection positions and bottom occlusion parts of the one or more than one half finished products. According to the present invention, a plate being subjected to product thickness design calculation is adopted, a lower main body of a product structure having a convex edge and at least an upper main body of a coiling shoe-shaped ingot are taken, the lower main body of the shoe-shaped ingot and the coiling upper main body are respectively have a necessary longitudinal section capable of mutually connecting and a coiling angle size, the tops and the bottoms of the half finished products are fixed or form sealing connections, and a pressing manner is adopted to make the micro sealing part perfectly close. The present invention provides a production process method with characteristics of low cost, high efficiency, high quality and high reliability.

Description

technical field [0001] The present invention relates to an industrial manufacturing technology, in particular to a method of using different materials (Wanzu gold, platinum, palladium, K gold, synthetic precious metals, silver sheets, etc.), irregular plane or three-dimensional shapes, and Different chamfering functions, different angles formed, the use of angle difference and the characteristics of the material form a chamfer of the inner and outer buckles, and the outer undercut of the product is combined with the inner chamfer difference of one or more assembled mold parts Angle fitting, using a constant pressure machine (including voltage, hydraulic pressure or stamping), and the multi-directional (longitudinal, horizontal, oblique, and up and down bite) thrust formed by the angle of each related workpiece, the blank of the proposed undercut position Correct it to a reasonable thickness and angle, combine two or more semi-finished products, and use the selected patterns or...

Problems solved by technology

[0005] Existing technology example 3. The process of electrocasting is firstly to make a master mold - make a rubber mold - make a wax mold - apply silver paste - electroforming - remove wax - remove silver paste - polish and calender; this process is the current traditional jewelry decoration Manufacturing process, because the production method of the product is formed by the principle of negative and positive electrodes, the particles are attached to the silver paste on the surface of the wax mold to form a material, and then the wax and silver paste are removed, and then polished and calendered, etc. procedure, it is impossible to maintain the original design style and meticulous line structure of the parts, and because the electroforming process requires a large number of precious metal blanks to form the electroforming cylinder, the finished product is controlled by the synthesis time of the microparticles, and the production cost is very high At the same time, because the appendages of precious metals are removed chemically in the post-process, the process requirements are very high, and the product quality is affected by the maintenance of the components in the electroforming cylinder, and the instability of post-process treatment cannot guarantee every product. Can reach ten thousand pure gold purity (999.9)

But its advantage is that it can manufacture smaller accessories, the cost of starting the mother board is low, and it can be mass-produced. The disadvantage is that it cannot keep the product 100% up to the original design style requirements, and the small production batch takes a long time to increase the cost, etc. shortcoming
