摘要
无缝钢管被广泛应用于石油管、锅炉管、高压输送管等工业现场,生产需求量非常大,在检测钢管时由于控制方面的限制,钢管之间间隔通常在3~6 m不等,为了提高生产率,减小管端盲区,自动探伤工艺需采用连续送料的工作模式,即钢管一根接着一根连续传输。因为间隙较小,传统传感器很难区分钢管端部信号并发送给超声波探伤仪,造成检测结果不能很好地匹配对应钢管,对自动分选下料也产生相应的影响。为了改善这种现象,设计了一种钢管头尾检测装置,能在钢管运行到检测主机入口时,即两根钢管头尾相撞时,检测装置在0.1 s内发出新钢管到达信号,通知PLC控制系统做出相应的信号处理,并发送给自动探伤系统开始探伤。
Seamless steel pipes are widely used in many industrial sites such as oil pipe, boiler pipe and high-pressure transmission pipe, and the production demand is very large. Due to the control restrictions in detection, the spacing between steel pipes is usually 3-6 m. In order to improve the productivity and reduce the blind area at pipe ends, the automatic flaw detection process needs to adopt the continuous feeding mode, that is, the steel pipes are continuously transmitted one by one. Because of the small gap, it is difficult for the traditional sensor to distinguish the end signal of the steel pipe and send it to the ultrasonic flaw detector, resulting in the detection results cannot match the corresponding steel pipe well, which also has a corresponding impact on the automatic sorting and blanking. In order to improve this phenomenon, a steel pipe head and tail detection device was designed. When the steel pipe ran to the entrance of the detection host, that was, when the head and tail of two steel pipes collided with each other, the detection device would send an arrival signal of new steel pipe within 0.1 s. It notified the PLC control system to make corresponding signal processing, and sent it to the automatic flaw detection system to start flaw detection.
