A communication relay high-speed cam type contact sheet silver wire spot welding feeding silver wire cutting mechanism

Abstract

The invention discloses a communication relay high-speed cam type contact plate silver wire spot welding silver wire feeding and cutting mechanism, which includes a lower roller shaft and an upper roller shaft, and a front upper stopper and a front lower stopper are arranged in front of the lower roller shaft. The back of the lower roller shaft is provided with a rear upper stopper and a rear lower stopper, and above the rear upper stopper is an upper roller plate that is raised relative to it. The upper roller shaft is connected to the upper roller plate in rotation. There is also a wire frame, the wire frame is provided with a wire frame shaft, and the front of the lower drum shaft is also provided with a lower electrode located in the output direction of the front upper stopper and the front lower stopper, and a blanking groove is provided on the upper end of the lower electrode , also comprises the cutting knife that is made close to or away from front upper stopper and front lower stopper, and silver wire part is cut off when cutting knife is close to front upper stopper and front lower stopper and falls into the discharge groove. The mechanism adopts two sets of cam structures to realize the characteristics of single power source input and double power source output, and completes the function of automatically cutting silver wire, and is easy to maintain and use as a whole.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, more specifically, it relates to a communication relay high-speed cam type contact plate silver wire spot welding feeding silver wire cutting mechanism. Background technique [0002] The high-speed cam-type contacts of existing communication relays need to weld silver contacts, and the silver contacts are mostly cut into small pieces from coiled silver wires, and then melted to realize welding. Most of the advanced equipment cannot realize automatic cutting of silver wire, and the power source is controlled by multiple sources, the internal structure is complex, the failure rate is high, and the overall effect is not good. Accordingly, the present invention proposes a communication relay high-speed cam type contact sheet silver wire spot welding feeding silver wire cutting mechanism. Contents of the invention [0003] The purpose of the present invention is to overcome the defici...
