Upsetting Machine Control System Based on the Embedded Technology
In this paper, based on the electrothermal upsetting processing method, the process of valve upsetting is divided into two steps: initial upsetting and formal upsetting. Four parameters, including 1.heatting current; 2.press; 3.velocity; 4.material, which influence the manufacture process in evidence, is mainly discussed. Analyzing defect and deficiency of tradition processing, the article puts forward to a controlling strategy with iteration technique and designed an embedded valve upset forging microcomputer control system. The electrothermal upsetting control system based on embedded technology stores the experience and technique of local worker, optimizes the tradition processing by using ARM S3C2410X chip. During the process, controlling parameters such as press, displacement and voltage are real-time monitored. Signal feeds back to system by sensors to realize the closed loop controlling on-line self-study function. And the technics parameters and the controlling process will display on the HMI (Human Machine Interface). Using the system, the quality and efficiency of the valve manufacture are improved, and the robustness gets stronger. The system has been applied in enterprises. Comparing with the tradition one, the automaticity in manufacture is improved, and the rejection rate is reduced. It also benefits the informationization of production of enterprise.
