Automation Retrofit Of QD160L Metal Profile Cutting Machine

With the rapid development of our economy, construction and manufacturing scale expands unceasingly,the demand of angle steel and other metal profiles cutting machine is increasing.At present some of the small and medium-sized metal material processing enterprises are still using manual cutting and semi-automatic cutting way to cut metal profiles.Traditional manual and semi automatic metal profile cutting machine can’t satisfy the use requirement in the machining efficiency and machining precision,etc.Urgently need a kind of automatic machine that can automatic and high precision to cut metal profiles.This paper according to the requirements of users to automatic retrofit the original QD160 L metal profile cutting machine.Based on PLC automation control platform for automatic sequence control, with touch screen as human-machine interface to monit and manage the running state of equipment.It has great significance in improving the efficiency and precision of the metal profile cutting machine.Through analyzing the present situation of domestic and foreign cutting machine and according to the shortage of the metal material cutting machine modification request,put forward the reform scheme of cutting machine.To set up the hardware platform of automatic cutting machine.Choose servo motor as the power source of the feeding device, After the power transfer of gear rack to realize feeding device linear motion.With STEP 7-Micro WIN SMART programming software to design program,with Win CC flexible graphical programming software to design the human-machine interface of touch screen.According to the motion mode of position for external connection and set the parameters of the servo motor.By using programming software of control wizard to configurate motion control of servo motor. Selection of measurement and control instruments for clamping device and cutting device and connect to PLC.In cutting machine feed port and discharging port increase security screen to achieve the safe operation of system, improve the reliability of cutting machine. By Ethernetcommunication mode to realize the connection of computer, PLC and touch screen.Automation retrofit of cutting machine has realized the accurate positioning of angle steel and other metal profiles that can be automatically processed.According to user requirements to cut different length of the metal profile.Control and running status of the equipment can operate on the touch screen visualization.To improve the machining efficiency of cutting machine and processing quality of products,which has important application value.
