Automatic Fins Inserting and Tube Expanding Machine for No Frost Evaporators
The Automatic Fins Inserting and Tube Expanding Machine is a specialized automated equipment tailored exclusively for the production of heat exchangers in no-frost evaporators, which are core components of modern refrigerators. It integrates precise mechanical transmission, intelligent control, and efficient processing technology, providing a reliable and high-efficiency solution for refrigerator heat exchanger manufacturing, effectively improving production quality and throughput.
As a key equipment in the no-frost evaporator production line, its core application is to manufacture high-performance heat exchangers for refrigerators. The heat exchanger processed by this machine directly affects the cooling efficiency, energy-saving performance and service life of the refrigerator, making it an indispensable core device for refrigerator manufacturers pursuing high-quality and efficient production.
The machine adopts a fully automated operation process, which greatly reduces manual intervention and operational errors, while significantly improving production efficiency. In the fin inserting link, it is equipped with a high-precision servo motor and a stable suction cup device: the servo motor ensures accurate positioning and smooth operation, and the suction cup can stably absorb, select and automatically insert fins into the designated positions, realizing continuous and automatic fin inserting without manual feeding and alignment.
After the fins are inserted, the hydraulic punch device starts to work. It exerts uniform and stable pressure to tightly fit the aluminum pipes with the fins, eliminating gaps between the two components. This tight fitting not only enhances the structural stability of the heat exchanger but also maximizes the heat transfer efficiency—ensuring that the heat exchanger can quickly conduct and exchange heat during the operation of the refrigerator, further improving the cooling effect of the no-frost evaporator and reducing the energy consumption of the refrigerator.
With its high automation, precise processing and efficient performance, this machine effectively solves the pain points of low efficiency, poor consistency and high labor intensity of traditional manual or semi-automatic fin inserting and tube expanding processes. It is easy to operate, has stable performance and low failure rate, and can adapt to the mass production needs of refrigerator heat exchangers of different specifications, helping enterprises optimize production processes, reduce costs and enhance market competitiveness.
