A copper-free welding wire production line and production process

Abstract

The invention relates to a non-copper plating welding wire production line and a production technology and belongs to the technical field of welding wire production. The non-copper plating welding wire production line is characterized by comprising a pay-off rack, an abrasive band polishing device, a rough drawing unit, a fine drawing unit, a cleaning box, a welding wire postprocessing device and a winding packing machine which are arranged in sequence. The technology sequentially comprises the steps that paying off is conducted, abrasive band polishing is conducted, reducing drawing is conducted, the cleaning box is used for preprocessing surface lubricating oil, and the welding wire postprocessing device is used for removing the surface lubricating oil and impurities and passes through the winding packing machine. The non-copper plating welding wire production line and the production technology have the advantages that the preprocessing acid-free rust removing technology and the welding wire postprocessing lubricating technology are thoroughly achieved, meanwhile, the surfaces of processed welding wires are even and smooth, and the wire feeding resistance is relieved.

Description

technical field [0001] The invention relates to a copper-free welding wire production line and a production process, belonging to the technical field of welding wire production. Background technique [0002] At present, in the field of welding, chemical derusting and mechanical derusting are generally used in the pre-treatment of welding wire manufacturing. Chemical derusting is mainly pickling and derusting. A large amount of pickling wastewater; mechanical derusting mainly includes shot peening and steel brushing, the process is simple and pollution-free, but the surface of the treated wire is prone to scratches, the cleaning speed is slow, and it is not easy to use with other equipment, etc. question. In addition, copper-plated welding wire produces a large amount of copper fume during welding. Inhalation of copper fume can cause metal fume fever, chills, elevated body temperature, and respiratory tract irritation symptoms. Long-term inhalation can cause pulmonary fibrou...

[0002] At present, in the field of welding, chemical derusting and mechanical derusting are generally used in the pre-treatment of welding wire manufacturing. Chemical derusting is mainly pickling and derusting. A large amount of pickling wastewater; mechanical derusting mainly includes shot peening and steel brushing, the process is simple and pollution-free, but the surface of the treated wire is prone to scratches, the cleaning speed is slow, and it is not easy to use with other equipment, etc. question

In addition, during the welding process of copper-plated welding wire, a large amount of copper fumes are produced. Inhalation of copper fumes can cause metal fume fever, chills, elevated body temperature, respiratory tract irritation symptoms, long-term inhalation can cause pulmonary fibrous tissue hyperplasia, etc.
