Research On The Aluminum-Plastic Door Window Sawing Machine Control System And The Optimization Blowdown Method

At present,the main control ways in automatization field are relay control,microcomputer control and PLC control.Compared with the relay control system and the microcomputer control system,the PLC control system has a series of advantages,such as little work load of designing,installing,wiring and debugging,short cycle of development,high dependability, strong ability of anti-interference,low trouble rate,low requirement of working environment and convenient maintenance.So the PLC control system has become the first-selected control project of the domestic and international machine processing control object.Meanwhile,the relay control system has been washed out on the machine processing control object because it is inferior in technique performance and single in function.This article models the aluminum-plastic door and window sawing machine of transform this concrete research topic,proposes with the PLC control system substitution original relay control system,uses the servo electrical machinery realization to point.Has compiled the optimazation blowdown software to realize optimization system,this promotes the original machine blowdown precision,the production efficiency and reduces the cost all to have the vital significance.The paper includes two parts:First has carried out the executive system part design, including based on PLC and the servosystem overall concept,the software and hardware design and realization plan,has given the concrete input/output wiring diagram,and has made the detailed elaboration based on the PLC control system electrical manchinery electric appliance control line,has designed the electric motor eletric appliance control line,elaboratec the electric motor main circuit and the electric appliande control circuit design process,has carded on the user program design,including the common program,the manual procedure,the semiautomatic procedure,and has given the trapezoidal chart;Next elaborated the optimized blowdown method,gave the optimized algorithm,has established the corresponding optimized blowdown program and has carried on the confirmation in upper computer part.
