Research And Development Of Auto Producing Finned Tube Machine

The machine (passing part) for auto producing finned tube is specializationequipment for producing finned-tube of radiator, which decides the quality andefficiency of finned-tube directly. Finned-tube is a heat exchange component thatusing helix metal finned slice to exchange heat, helix metal finned slicecontinuously round on the surface of the metal. The finned tube is recognized asa high effect heat exchange component and economical product in the wholeworld. As the development of air-condition and refrigeration, more and morefinned-tube are needed, and more function, better quality, higher costperformance, the circle of upgrade of products are also required. This system iscontrolled by manual and semi-mechanical, so leads to lower productivity,instability and not satisfy the clients' contents. And all these are depended byAluminum-rounded machine. Its performance can not be improved just byimporting from foreign country. So it needs to design auto-finned-tub, based onresearch of aluminum-rounded machine.This passage design auto- aluminum-rounded machine, adopt PLC to controland make numerical control come true. It also uses frequency conversion tocontrol tube to revolve and feed, so can realize stipples speed regulating, at thesame time, the material can be auto-installed and un-installed, so can realize automanufacture. Through the strength design and verify calculation of importantpart in finned tub, finish the whole fabric design of auto- aluminum-roundedmachine. Change single tube to double ones. Its power increase to twice asbefore; put an equipment which can alter diameter on driving gears; on thebaiting device flexible using automatism send material device, make automatismsend material come true; on control using plc as the main controlling equipment. And by frequency converter circuit, we can achieve different diameters and pitchscrew.The problems of half machinery, half manual operation way, low efficiency,unstable quality and few specification of the tradition auto aluminous-windingmachine are solved in this thesis. The series of the modulating velocity of theproduct screw-pitch gauge are realized, and the program management, parameterpre-establishment, automatic and manual functions are realized too. Theproduction efficiency and automatization level of the enterprise can be enhanced,and finally the competitive ability of the enterprise can be improved.
