At present, in the continuous extrusion and continuous coating of nonferrous metals such as copper, aluminum and the like and the manufacture of cables in the wire and cable industry, the continuous extrusion is mainly used for the continuous extrusion and continuous coating of copper, aluminum and alloy metals and is also used for the manufacture of cables in the wire and cable industry. The working principle of the continuous extruder is as follows: the extrusion wheel is driven by a motor to rotate, the rod blank enters an extrusion wheel groove, the metal rod blank is drawn into an arc extrusion cavity formed by the extrusion wheel and a cavity under the action of friction force of a groove wall, under the action of high pressure and high temperature generated by the friction force, the copper and aluminum rod blanks are extruded through a die orifice, and main products comprise copper, aluminum flat wires, pipes, bar row sectional materials, cable aluminum sheaths, aluminum-clad steel wires and the like.
When the extrusion wheel is under the action of extrusion force during working, and the friction action between the extrusion wheel and the blank enables the position near the groove of the extrusion wheel and the outer surface of the extrusion wheel to be in a high-temperature state. The extrusion wheel is a main wearing part in the continuous extrusion production process, and the cost of the extrusion wheel accounts for more than 30% of the total cost of the continuous extrusion tooling die. Therefore, technical measures are needed to prolong the service life of the extrusion wheel and reduce the production cost.
