Abstract
The present invention discloses a roll forming device for micro-casting and rolling additive manufacture for large special-shaped pipes, comprises a supporting assembly, a sliding assembly, and a roller system assembly. The sliding assembly includes a guide rail, hydraulic cylinders, hydraulic push rods and a guide rail sliding frame. Two ends of the guide rail are respectively fixedly connected with the centers of two ends of the frame plate in a width direction, the lower surface of the sliding plate of the guide raid sliding frame is slidably connected with the guide rail, housings of the hydraulic cylinders are respectively fixedly connected to the centers at both ends of the frame plate in the width direction. The invention adopts the structures of the guide rail, the hydraulic cylinder and the steering hinge rod to expand the working range of the device and the working types of workable parts.
