Abstract: In order to solve the problems of hard cleaning of cutting-spatter and heavy manual workload associated with the steel pipe production line,a set of automatic cleaning device for spatters on the inner surface of the steel pipe end is designed. Described here in the article are the main aspects of the said cleaning device,including the design ideas,the main structure and the workflow. With the device the high-speed rotating steel wire grinding head is driven via the motor to clean the residual splashes left on the inner surface of the steel pipe,and the grinding pressure is properly controlled via the pneumatic cylinder. The device is designed following the principle of miniaturization and lightweight. The site operation result of the device shows that the high-speed rotating steel wire grinding head is capable of removing the cutting spatter and other foreign matters sticking upon the surface of the steel pipe under a certain contact pressure. The cleaning device features significantly increasing the efficiency and quality of cutting-splash cleaning, material saving,high cleaning effectiveness,and reduction of both labor intensity and labor cost.
