JPS5641014A - Manufacture of composite wire - Google Patents

Abstract

PURPOSE: To continuously manufacture the composite wire, by feeding the coating material and the core wire to the engaged circumferential end planes of the hollow- grooved rolls engaging with each other and rotating in the opposite directions, and by extruding thus pressure welded materials through the die.

CONSTITUTION: The grooved rolls 1, 2, provided wiht the hollow grooves 3, 4, at their circumferential end planes, are arranged so as to engage with each other at their circumferential end planes, and are rotated in the opposite directions X, Y. The coating rod materials 16, 17, of aluminum rod, etc., are fed into the feeding port of the hollow grooves 3, 4, and also, the core wire 7 of the steel sire, etc., is fed into the feeding path 8 of the stationary sealing block 5. The coating rod materials 16, 17, are pressure welded by the hollow grooves 3, 4, and arrive at the cavity 6 formed by the hollow grooves 3, 4, and are pushed into the space 10 of the cavity 6 by the friction force between the rod materials 16, 17, and the wall surfaces of the hollow grooves 3, 4, under the condition that the rod materials 16, 17, are sticking around the core wire 7. This composite material is extruded through the die 11, installed closely to the space 10 integrally with the stationary sealing block 5; hereby, the composite wire 13, in which the core wire 7 is coated by the coating materials 16, 17, is continuously manufactured.
