Description

A semi-automatic egg-shaped bracelet shaping machine

technical field

The utility model relates to the technical field of bracelet processing equipment, in particular to a semi-automatic egg-shaped bracelet shaping machine.

Background technique

Bracelets are circular ornaments worn on the wrist made of gold, silver, jade, etc. As people's requirements for the comfort of bracelets increase, some oval-shaped bracelets gradually appear on the market. People habitually call them egg bracelets. shaped bracelet.

When the egg-shaped bracelet is processed, it is often necessary to use a bracelet shaping machine to shape and polish the inner ring of the bracelet. The purpose is to make the inner ring have better smoothness. Since the size of each batch of bracelets is different, it is necessary to use Then put the bracelet into the mould, and put the mould into the shaping frame to carry out the shaping and polishing operation. During this step, there is a need to remove the old mould. Take it out from the shaping frame and install a new mold. In the existing technology, the clamping structure of the mold is usually locked by two bolts, because it is often necessary to replace it according to the size of the current batch of bracelets. Due to the matching mold, the staff needs to continuously twist the two bolts to loosen and clamp the clamping structure. On the one hand, it is difficult to determine whether the force exerted by the two bolts is uniform when tightening, and it is difficult to ensure that the mold can clamp stably. On the other hand, screwing two bolts back and forth takes more time for the staff, which is difficult to improve work efficiency.
