Continuous Extrusion Production Line for copper wire and small bus bar 1. Summary
The structure of the machine is the grooved wheel and shaft assembly. The main shaft is driven by an infinitely variable, thyristor controlled DC electric motor, via an epicyclical gearbox. The power output envelope from the drive is matched to the production rates specified by operator. There is mount roller bearings that incorporate multiple seals to retain oil and prevent the ingress of foreign material. The Coining roll assembly to coin the feed rod firmly in the wheel groove. The shoe contains the die-chamber assembly can be opened and closed easily by hydraulic cylinder, high pressure cylinder used to support the shoe in working position. With supplement tooling, the extrusion wheel of the machine can be replaced easily. Exchange chamber and die is also very fast.
