[0002] When producing steel pipes, most of them need to be chamfered at the ends. When chamfering, the position of the steel pipe needs to be fixed and placed at a position corresponding to the chamfering unit. In order to meet the above requirements, the steel pipe step-by-step pipe moving device came into being. In the past, the steel pipe step-by-step pipe moving device mostly had a transmission mechanism of chain or belt drive. Since the steel pipe step-by-step pipe moving device usually consists of two groups, and the transmission mechanism of this structure is affected by the tightness of the chain or belt, the synchronization of the two groups of steel pipe step-by-step pipe moving devices will be affected to a certain extent, thereby affecting the chamfering operation. In view of the shortcomings of previous technologies, our company independently developed and designed a gear-driven steel pipe step-by-step pipe moving device, which better solved the synchronization problem of the two groups of steel pipe step-by-step pipe moving devices.
