Description

Technical field: [0001] The invention relates to production equipment for bimetallic composite wires such as copper-clad aluminum and copper-clad steel, in particular to a high-efficiency production line for bimetallic composite wires that can reduce labor intensity of workers, ensure continuous production, and increase yield. Background technique: [0002] At present, the production method of copper-clad aluminum, copper-clad steel and other bimetallic composite wire blanks is mainly the cladding welding-drawing method. The specific production method is to pull the aluminum rod (steel rod) through the aluminum rod drawing machine, and then manually degrease the drawn aluminum rod with alkaline water soaking, and finally wrap the aluminum rod around the aluminum rod for feeding. At the same time, the copper strip on the copper strip discharge rack is pretreated through the cleaning tank, copper strip drying machine, copper strip trimming machine, and copper strip grinding ma...

Problems solved by technology

[0003] 1. Since the copper strips are mounted on the material rack in coils, and each coil is only a few hundred meters long, after welding a coil of copper coils or aluminum rods, it is necessary to stop the machine and change another coil of copper coils or aluminum rods to ensure that the cladding welding The production process cannot be carried out continuously, and the downtime is long, which reduces the production efficiency of the wire blank, and at the same time cannot produce large and heavy bimetal composite wire blanks;

[0004] 2. The alkaline water soaking surface pretreatment method of aluminum rods is backward, the labor intensity of workers is high and the quality is greatly affected by human factors. If the oxides on the aluminum rods are not completely removed, the metallurgical combination of copper and aluminum will be seriously affected , resulting in a low yield of products, and alkaline water waste and residues must be treated to meet environmental protection requirements, increasing production costs;

[0005] 3. The welding current of the argon arc welding machine and the driving speed of the overmolding machine are independent of each other and not related to each other. The welding current cannot be adjusted in time with the change of the driving speed of the overmolding machine. At the welding seam, due to the relatively slow driving speed and the relatively high current of the argon arc welding machine, the copper strip is perforated, resulting in the interruption of continuous production;

[0006] 4. It is impossible to monitor the burning condition of the tungsten electrode in real time, so that the argon arc welding machine cannot use a large welding current, and the welding speed of the wire blank is low (only 5-7m can be welded per minute), which further reduces the production efficiency of the product
