Cooling fin double-gun plasma welding machine

Abstract

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.

Description

technical field [0001] The invention relates to a plasma welding machine with double guns for heat sinks. Background technique [0002] The traditional welding of heat sinks is generally done by hand-held welding torches. The manual welding operation method not only has the problems of low welding accuracy, low welding efficiency and poor welding effect, but also has the labor force of workers. The strength and the high labor cost of the enterprise are insufficient, and it does not meet the requirements of large-scale and mass production of the enterprise. Later, some automatic welding machines appeared on the market, but their welding process requires the use of flux. The use of flux will cause certain harm to human health, and it does not meet the requirements of enterprise safety and environmental protection production.

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a plasma welding machine with double guns for heat sinks, which can realize the positioning of the stacked circular workpieces before welding through the mold mechanism, and can automatically position the circular workpieces stacked together through the double gun gear rotation mechanism. The middle round hole in the two stacked round workpieces is welded on the inner circle edge, so that the two round workpieces can be welded together after being welded through the inner circle edge of the middle round hole, and the welding process does not require manual labor. Participate in the operation, which has the advantages of high welding precision, high welding efficiency, good welding effect, high labor intensity of workers and high labor cost of the enterprise, which effectively solves the problem of low welding precision and low welding accuracy of traditional manual welding of heat sinks. The problems of low welding efficiency, poor welding effect, high labor intensity of workers and high labor cost of enterprises
