Embodiment Construction

[0025] Such as figure 1 As shown, a method for making bowl-shaped ornaments mainly includes the following steps: material preparation 1, preforming 2, forming 3, correcting 4, inner surface polishing 5, shaping 6, deburring 7 and outer surface calendering 8. Polish the surface of the plate with the thickness required for the bowl-shaped ornament, and then obtain the blank required for the bowl-shaped ornament on a punching machine; draw the blank into a shape with an opening size greater than or equal to the cavity size through a preforming die Bowl-shaped semi-finished product; the semi-finished product is molded into a bowl-shaped workpiece with a maximum cavity size greater than the opening size through a sizing die; The supplementary weight of the standard weight is trimmed to the range required by the standard weight; after the bowl-shaped workpiece is annealed and pickled, the inner surface is polished, and the polishing of the inner surface includes placing the bowl-sha...

Abstract

The invention discloses a bowl type ornament manufacturing method and belongs to the technical field of ornament manufacturing methods. The bowl type ornament manufacturing method mainly comprises the following steps: preparing raw materials, pre-forming, forming, correcting, polishing internal surface, sizing, deburring and polishing external surface, wherein a sizing die is used for sizing, thesizing mold comprises a sizing upper die holder and a sizing lower die holder, the sizing upper die holder is sleeved with a sizing male die, the sizing lower die holder is provided with a sizing female die, an impression die hole is formed on the sizing lower die holder, an impression die is restrained and arranged in the impression die hole, the sizing female die comprises a plurality of femaledie segmental bodies which are arranged in an array around the center of the impression die hole and is arranged on the sizing lower die holder in a way of being capable of sliding along the radial direction of the impression die hole. In the invention, the technical problem of processing workpieces, of which the maximum sizes of the molding cavities are greater than the sizes of openings, by using a drawing die is solved, and the method can be widely used in ornament processing industry.

Description

technical field [0001] The invention relates to the technical field of jewelry making methods, in particular to a method for making bowl-shaped jewelry. Background technique [0002] Gold and silver ornaments are favored by people for their dazzling appearance and their own value. Among gold ornaments, there are bowl-shaped ornaments, which are similar in shape to bowls, and are very popular among people for their implication and the preciousness of their materials. [0003] In order to achieve mass production, the production of bowl-shaped ornaments is usually realized by casting process. However, the surface quality of the bowl-shaped workpiece after casting is often not high, and the follow-up processing process is relatively complicated. The traditional manufacturing process of open jewelry is obtained by drawing sheet-shaped plates with molds, which has high efficiency and good surface finish. However, because the maximum size of the bowl-shaped jewelry cavity is larger...
