Embodiment Construction
[0014] The present invention will be further described below in conjunction with specific embodiment:
[0015] refer to Figure 1 to Figure 2 Shown, a kind of precious metal product seamless forming process of the present invention comprises steps:
[0016] (A) pressing the precious metal material into a precious metal sheet 2 with a thickness of 0.5 mm to 5 mm;
[0017] (B) pressing the precious metal sheet 2 through a top block 1 and affixing it to the bottom of the precious metal product mold;
[0018] (C) Synchronously rotate the top block 1 and the precious metal product mold, and use the milling cutter 3 to press the precious metal sheet 2 close to the outer wall of the precious metal product mold, wherein, the milling cutter 3 starts from the bottom end of the precious metal product mold in the axial direction to form the precious metal product mold The outer wall profile moves as a trajectory.
[0019] The milling cutter 3 presses the precious metal sheet 2 and move...

Abstract
The invention discloses a seamless forming process for a precious metal product. The process comprises the steps that (A) precious metal materials are pressed into a precious metal sheet with the thickness of 0.5mm-5mm; (B) the precious metal sheet is tightly pressed by an ejector block and attached to the bottom end of a precious metal product mold; (C) the ejector block and the precious metal product mold are rotated synchronously, the outer wall, tightly attached to the precious metal product mold, of the precious metal sheet is tightly pressed by a milling cutter, and the milling cutter moves from the bottom end of the precious metal product mold in the axial direction with the outer wall contour of the precious metal product mold as the track. The seamless forming process for the precious metal product has the advantages that seamless and welding-free forming is realized, the durability of the precious metal product is improved, the service life is prolonged, and the surface luster of the precious metal product is more natural because of integrated forming; besides, the seamless forming process realizes rapid forming of the precious metal product, the production cycle is shortened, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to a precious metal product forming process, in particular to a precious metal product seamless forming process. Background technique [0002] Precious metal vases, teacups, and gold and silver bowls currently on the market all need to be formed by hand and oil pressure. Taking precious metal vases as an example, the parts where the neck of the vase is in contact with the body of the vase, and the bottom of the bottle and the table must be divided into two parts, which are processed and formed separately. Finally, it can be formed after welding with gold bars and silver bars, and polishing at the interface. The production cost of this type of precious metal vase is high, and the material loss is large. After the welding joint is used for a long time, it is easy to fall off, and the maintenance and repair costs of precious metal vases are high. Contents of the invention [0003] The purpose of the present invention is to overco...
