Abstract

The present invention relates to a rotary press shaping technology and a device thereof. The technology is mainly realized by dividing the movement of a roller into two movements vertical to each other and driven by a hydraulic transmission mechanism, and the moving stroke of the hydraulic transmission mechanism is controlled by a control device. The control device can divide the movement of the roller into two movements vertical to each other according to the external shape curve of hollow articles to be processed and shaped, such as marmite bodies, and convert the two movements into the flow speed of hydraulic oil used for driving corresponding hydraulic transmission mechanisms to move. Then the control device can be used for control the oil-supplying flow speed toward the hydraulic transmission mechanisms vertical to each other according to the flow speed parameters of the hydraulic oil. A roller can be drawn by a rotating core mould, and can be pressed into the hollow products, such as the marmite bodies, in the required shapes by using blank materials clamped by a tail supporter. Compared with the prior art, the present invention has the advantages of accurately, effectively and reliably realizing the strong-force rotary production of hollow products with rich appearances.
