Abstract
The present disclosure discloses an ultra-low pressure liquid filling forming system for a special-shaped component, including a control system, a supercharger, a driving device, a preforming unit, and a final forming unit. The present disclosure further provides an ultra-low pressure liquid filling forming method for a special-shaped component, including the following steps: S1: making an equal diameter cylindrical coil blank with an overlapping part in a longitudinal direction by using a plate blank; S2: bulging the equal diameter cylindrical coil blank into a variable diameter cylindrical prefabricated coil blank; S3: cutting and welding the overlapping part remaining on the variable diameter cylindrical prefabricated coil blank in the axial direction to obtain a variable diameter prefabricated tube blank; S4: filling liquid and press-forming the variable diameter prefabricated tube blank, so that the variable diameter prefabricated tube blank occurs compressive deformation, thereby forming the special-shaped component.
