Abstract
In the field of nuclear industry, pipe components are often used as common parts. Because the processing process will bend the pipe components, it needs to be straightened before leaving the factory to meet the practical application. In order to improve the detection accuracy and processing efficiency of pipe components, the control system of intelligent straightening equipment is designed according to the manual straightening method. According to the characteristics of end jump detection, an algorithm based on secondary data filter is designed to achieve high precision measurement. According to the material and structure characteristics of the components, an adaptive algorithm of downdraft is designed to realize difference recognition and automatic calculation. By studying the manual process and combining with the theory of automatic control, an efficient and safe automatic testing and straightening process is designed, which realizes the standardization and intelligence of straightening. Using STM32F407 self-developed main control unit, data communication, algorithm calculation, logic control, data access and fault detection are realized. Combined with touch screen, the whole process of detection and alignment is visualized. The intelligent straightening equipment with this control system has been used in practical production. The detecting precision and straightening efficiency are greatly improved. It has friendly human-machine interaction mechanism and reliable safety protection mechanism to meet the actual production needs.
