The invention discloses a cooling fin double-gun
plasma welding machine. The cooling fin double-gun
plasma welding machine comprises a support. A mold mechanism is arranged on the front side of the support, a lifting cylinder is arranged on the front side of the upper end of the support, and a double-gun gear rotating mechanism is arranged at the bottom of the lifting cylinder. The mold mechanismcomprises a jacking cylinder, a base plate, a moving lower mold plate, a fixed upper mold plate, guide sleeves, lower locating
copper columns, lower locating stretching cylinders, upper locating
copper square blocks and cooling water connectors. By the adoption of the integral structural design, the purpose that the inner circle edge
welding can be fully automatically conducted on middle circularholes in two circular workpieces which are stacked together is achieved, the purposes that the labor intensity of workers can be greatly reduced, the service cost of an enterprise can be reduced are achieved, and utilization is more convenient. Double
plasma welding guns can achieve synchronous welding, are high in welding efficiency and conduct locating on the stacked circular workpieces throughthe arranged mold mechanism, and therefore the double-gun gear rotating mechanism can have the advantages of being high in welding accuracy and good in welding effect, and the cooling fin double-gun plasma welding
machine meets the requirement of the enterprise for the large-scale
batch production.
