Design And Research Of Measurement And Control System For Multi-station Nut Forging Conveying Equipment

As far as the development trend of modern industrial society is concerned,the industrial production process is moving toward the goal of standardization,integration and automation.At present,some small and medium-sized nut processing enterprises still use traditional processing methods to manually process and transport nut blanks on the forging process equipment.This processing mode has low production efficiency,unstable product quality,dangerous work environment for workers and many problems are caused by the increase in labor costs and the difficulty of recruiting workers.Therefore,this paper designs a multi-station nut forging processing and conveying equipment for the problem of auto-forging process automation,to solve the problems of the backwardness of the nut forging process and the instability of the product quality.This paper mainly deals with the multi-station nut forging processing.Research and design of the equipment’s measurement and control system and position control algorithm.Firstly,according to the composition of the forging processing equipment,the process flow,the processing characteristics and the production requirements of the enterprise,two kinds of conveying schemes that meet the requirements are proposed.The fast crossbar conveying scheme that best meets the design requirements is selected,and the measurement and control system of the scheme is determined.Structural composition and control requirements.Combined with the work flow and design requirements of the multi-station nut forging conveying equipment,the overall structure of the measurement and control system was completed,including the hardware selection of the lower machine control system,the design of the pneumatic and electrical parts and the preparation of the PLC program,and the control of the upper computer control system.Touch screen interface design and communication between PLC and touch screen,PLC and servo motor.Secondly,combined with the working principle of multi-station nut forging processing and conveying equipment,the position control system of the equipment is analyzed,and the mathematical model of the overall position control system is established.According to the characteristics of the position control system,the position control algorithm of adaptive fuzzy PID is proposed.On this basis,the overall simulation model of the position control system is established by Matlab/Simulink.Thesimulation results show that the proposed position control algorithm solves the problems of large overshoot,weak anti-interference ability,large parameter influence,slow response speed and poor steady-state accuracy in the position control process,which makes the position control system have good dynamic and static characteristic.Finally,the multi-station nut forging processing and conveying equipment prototype was built,and the hardware,communication and software programs were debugged.The debugging results showed that the hardware installation was reasonable,the function was normal,the configuration communication was good,and the software program met the functional requirements.On this basis,the performance test of the prototype of the equipment was carried out,including the fixed length test and the transport capacity test.The experimental results show that the multi-station nut forging processing conveying equipment exhibits high positional accuracy and strong conveying capacity.It can meet the automation requirements of the nut forging conveying process.
