The invention provides a heat exchanger oval tube fin punching technology which can achieve continuous machining and continuous forming, and is high in efficiency and safety. The heat exchanger oval tube fin punching technology is characterized by comprising the following steps of stretching, wherein strip materials formed by winding are sequentially punched and stretched into groove shapes; (2) punching and flanging, wherein the grooves, formed in the step (1), of the strip materials are punched and flanged; (3) bridge piece punching, wherein bridge piece punching is conducted on the strip materials at the rear end of a hole; (4) secondary flanging, wherein secondary flanging is conducted on the hole formed through punching and flanging in the step (2); (5) cutting, wherein the strip materials are cut longitudinally, and product blanking is achieved; (6) material pulling, wherein the strip materials are pulled to a next working station; (7) transverse cutting, wherein board materials of the formed oval hole are cut transversely, and product blanking is achieved. The invention further provides a die special for heat exchanger oval tube fin punching and machining.
Description
technical field [0001] The invention relates to the technical field of product processing technology and molds thereof, in particular to a heat exchanger elliptical tube fin stamping process and a special mold thereof. Background technique [0002] As a process equipment in heat transfer, heat exchangers are widely used in industrial fields. With the increasing shortage of various energy sources, the rational design, operation and improvement of heat exchangers are very important to save money, materials, energy and space. As a compact heat exchanger, the finned tube heat exchanger is widely used in power, chemical industry, refrigeration and other industrial fields, and has high heat exchange efficiency. Usually, its base tube is a round tube. The research found that the oval tube has smaller resistance loss. Compared with the conventional circular tube heat exchanger, the main difference between the elliptical tube heat exchanger is that the circular tube is replaced by ...
