Patent ID: 10058959

Abstract:
A method for remanufacturing an ultra-large copper nut includes steps of: step (1) coarsening treatment; step (2) purifying treatment; step (3) detecting a material of the ultra-large copper nut; step (4) sleeving a thermal insulation device; step (5) preheating the ultra-large copper nut; step (6) melting-deposition shaping; step (7) post-processing; and step (8) detecting. The method of the present invention simultaneously utilizes water, electricity, gas, fire and machine and performs melting-deposition on materials by simultaneously supplying water, electricity, gas, fire and machine according to the designed requirements. The method of the present invention solves problems of large thickness abrasion and remediation of fracture components. The method of the present invention is capable of preventing the ultra-large copper nut from deformation and collapse and is a feasible remanufacturing for decreasing the huge economic loss caused by damages of expensive ultra-large of nonferrous metals.
