[Abstract]:Spring is a basic component, widely used in construction machinery, machinery and equipment, energy, aerospace, textile, automotive and other industries. With the development of industrial modernization, the demand for the precision and space shape of spring is increasing. However, the production capacity of domestic spring processing equipment is limited and the technology is backward, most of the CNC system of spring winder depends on import. The imported equipment is not only expensive but also does not support secondary development. Therefore, the solution of setting up hardware and software platform with computer programmable Automation controller (CPAC) as the control core is put forward. Through hardware selection and software modularization development, the design of open spring winder control system is realized. The specific research contents are as follows: according to the forming principle and process analysis of spring, combined with the mechanical structure and working principle of NC spring winder, the general scheme of open and modular spring winder system is established. According to the processing characteristics and control requirements of spring coiling machine, the hardware structure of the control system is determined. The controller of GUC series, which is developed independently by GUC, is used as the control core of the spring winder, and the servo motor and HMI man-machine interface are combined. The hardware control platform of the system based on CANopen bus is constructed. By using the software development platform of Otostudio, the modularized design of "plug and play" module for the control system of the coiling spring machine is carried out, the spring winding program is written, the standard communication interface is defined, the man-machine interface is developed to facilitate the user operation, and the open design of the system is realized. Convenient secondary development and upgrade. The acceleration and deceleration motion of spring winder is studied, the mathematical model of acceleration and deceleration optimization algorithm is established, the simulation analysis is carried out by MATLAB, and the control system of spring winder is tested. The test results basically meet the design requirements.
