Description

Technical Field

[0001] The utility model relates to the technical field of jewelry processing, in particular to a winding and cutting machine. Background Art

[0002] Spring clasps for jewelry are generally used in K gold jewelry (necklaces, bracelets, anklets) and 925 silver jewelry to connect chains. The spring clasp includes an annular buckle (also called a shell), a spring and a movable buckle. The buckle is cut to form a buckle interface that can buckle the necklace. During processing, the spring is first passed into the large ring, and the movable buckle is assembled in the buckle from the loading port set on the outside of the shell. One end of the movable buckle abuts against the spring, and the other end abuts against the other end of the buckle. The movable buckle slides along the cavity of the buckle to open or close the buckle interface.

[0003] Normally, when producing buckles, a section is first cut from the bobbin, which is then clamped to the molding position by a robotic arm and molded through multiple molds. It is impossible to mold and demold at one time, resulting in low processing efficiency, large equipment size and high cost. Currently, there are also methods on the market that use a molding mold to complete the molding process at one time, so that the bobbin is molded into a ring shape, with a simple overall structure and low manufacturing cost. However, this method only molds the bobbin into a buckle, and a cutting machine is required to cut it after molding, resulting in low production efficiency and low processing quality, which cannot meet the use requirements.
