In the modern metal processing industry, copper plays an indispensable role in many fields such as wires and cables, electronic components, radiators and architectural decoration due to its excellent electrical conductivity, thermal conductivity and corrosion resistance. However, to process the original copper billet into fine wires or profiles that meet specific requirements, efficient and precise processing equipment is indispensable. Among them, large-medium-sized copper continuous annealing wire drawing machines (hereinafter referred to as "continuous annealing wire drawing machines") have become an important tool in the field of copper processing with their unique process advantages and technological innovations.
The continuous annealing wire drawing machine integrates the two core processes of wire drawing and annealing, realizes the instant annealing of copper during the stretching process, effectively eliminates the internal stress caused by stretching, and improves the flexibility and ductility of the material. The equipment is usually composed of key components such as a wire unwinding device, a multi-stage wire drawing die set, a continuous annealing furnace, a cooling system, a wire take-up device and a control system. The pay-off device is responsible for smoothly feeding the copper billet into the wire drawing area, and gradually reducing the diameter to the target size through a series of precisely designed wire drawing dies; the continuous annealing furnace adopts efficient heating technology to ensure that the copper material enters the annealing state immediately after drawing, and the temperature and time are precisely controllable; the cooling system quickly reduces the temperature of the copper material after annealing and stabilizes its organizational structure; finally, the take-up device neatly winds the finished copper material for subsequent processing or storage.
