Design of PLC Control System in Automatic Production Line for Casing Fin Tube

Finned tube is a kind of highly efficient heat exchange component, widely used in heat exchanger. In order to improve the automation level of finned tube production line, this paper, according to the composition of finned tube production line and the function of each part, designed the control scheme of the production line, including motor drive technology, hydraulics technology, PLC control technology etc. The control scheme makes raw material of aluminum sheet feeding, punching, shearing, winged, tube expanding process to form a whole, which improved the efficiency of the production line and the processing precision.
