Description

Technical Field

[0001] This invention relates to the technical field of electronic connectors, and in particular to a stamping device for electronic connector pins. Background Technology

[0002] Electronic connectors, also known as circuit connectors, electrical connectors, or plugs, are components used to connect two conductors or electronic / electrical systems. Their core function is to easily connect or disconnect a circuit when needed, allowing current or signals to flow stably from one conductor to another. Electronic connectors use pins, which require stamping equipment for processing during manufacturing. In the existing stamping device, multiple sets of support frames and guide wheels are set in multiple placement cylinders respectively. Under the action of the guide wheels, the pin is stably supported in the placement cylinder, which makes the stamping accuracy higher and improves the stamping work quality. However, after actual stamping, the stamped pins need to be removed from the placement cylinder and reloaded before stamping can continue, resulting in low work efficiency. Furthermore, since the pins are held between the support frame and the placement cylinder, the operation is quite laborious when removing the pins. Therefore, there are areas for improvement.

During this process, the turning roller 4 drives the roller 51 to roll from the side of the fixed ring 52 to the convex strip 53. The driving rod 50 drives the lifting plate 46 to move. The pushing block 47 on the lifting plate 46 pushes the stamped pins in the placement cylinder 5 out to the collection box 27 for collection. While the pins are being discharged, the stamping work of the pins continues in the placement cylinder 5 which is in the stamping position. The working time is used reasonably and the stamping efficiency is improved.
