Description

Technical Field

[0001] The invention relates to a necklace chain punching device. Background Art

[0002] Chain accessories such as necklaces generally need to be stamped during the production process. For example, the joints of the lip chain need to be stamped and recessed during the processing. The stamped lip chain has the characteristics of light weight and large volume, which effectively improves the aesthetics of the chain. Most of the stamping machines used for conventional chains allow the hammer to directly punch and hammer the chain, and the chain moves in the center of the die base driven by the motor. However, during the continuous movement of the chain, it is very easy for the chain to move offset, stack or misalign due to the environment or other unexpected situations, causing the stamped chain to deform, be out of position or have inconsistent stamped shapes. It is not only difficult to ensure the shape consistency of the chain during continuous processing, reducing the production quality of the chain, but also very easy to cause material waste in the chain stamping process, and require the producer to take extra time to replace the damaged chain, increasing the production time and labor intensity of the producer in processing the chain.
