4. Extrusion Machine Descriptions:
The cooling system consists of machinery cooling water tank and product cooling water tank. The machinery cooling is water cooling of wheel and machinery. The product cooling system and cleaning utilizes softened water together with anti-oxidants and brighteners to enhance the product quality. The product is drying after exit cooling system.
The structure of the Extrusion 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.
Both of them adopt circulating water system with pumps and plate heat exchangers with outer water. The outer water then be cooled by cooling tower or deep well.? Thus makes a closed recycle system and the water waste can be minimized.
Length counter is in-line length electro-mechanical length counting with a roller driven LED apparatus which operate at all-line speeds and set up to display the product length in digit.
The Product line speed counting can be done at the MMI computer.
The product can be wound onto a normal drum to produce coils of wires. The take-up control system is designed to handle a wide range of products and can be operated with various tensions down to near zero. Product coil can be taken from the shaft quickly and easily.? It uses standard DIN drum, the size is 2500mm.
