Description

Automatic processing apparatus of ear ring pin

The present invention relates to an automatic earring pin processing device, and more particularly, to process the earring pin pinned to the ear by pulling the wire wound continuously in a straight line and cutting it to a certain length while rounding the end of the earring pin. The present invention relates to an earring pin automatic processing apparatus capable of automatically and continuously processing earring pins having a very small diameter by processing the engaging grooves.

In general, jewelry earring pins are rounded in circular arcs, so they won't hurt when plugged into the ear. And the end of the earring pin is formed with a locking groove to stop the earring pin so that the earring pin does not easily fall out of the ear.

However, earring pins have a disadvantage in that workability is degraded because a very small diameter wire is cut to a certain length and one end is directly processed into an arc surface. In addition, after processing into circular arcs, the second grooving process is required on the outer circumferential surface, and thus productivity is different according to the working skill, and the human cost must be directly processed to increase the labor cost, resulting in higher product prices.

The present invention was developed in view of the conventional problems, the object of the present invention is to pull the wire wound in succession and pull out to be a straight line without cutting to make a earring pin to be cut into a certain length round the end of the earring pin By processing circular arcs and processing the outer circumferential surface of earring pins to a certain depth so that the locking grooves that stop rings are machined, the earring pins with very small diameters can be machined continuously to improve productivity and reduce production costs. It is to provide an earring pin automatic processing device that can be lowered.
