In order to increase output of pipe straightening devices, there is provided a driving unit between a preparatory station for the pipes and a feeding station which advances the pipes from the preparatory station in axial direction one after the other in the feeding station. The feeding station includes a succession of rotation symmetrical guiding elements supported for rotation about axes which extend parallel to the feeding path for the pipes. The guiding bodies prevent striking of unbalanced pipes against the feeding unit and permit axial feeding of the pipes in a straightening station.
A workstation has a base, a conveying device, a driving assembly and a working device. The base is composed of multiple supporting frames. The conveying device is mounted on the base and has a rail, a moving base, a motor, a pushing rod and two rotating rods. The rotating rods are rotatably mounted on the base and are parallel with each other. Each rotating rod is composed of multiple connecting rods and multiple connecting elements. The connecting rods are combined with each other, and the connecting elements are mounted respectively between the connecting rods to connect adjacent connecting rods together. The driving assembly is mounted on the base to drive the rotating rods to rotate along a same direction. The working device is mounted on the base to process a manufacturing process to a worked object.
