Abstract

The invention provides a revolving body part liquid-filling forming device. The revolving body part liquid-filling forming device comprises a male die (1), a female die (3) and an edge pressing ring (2). The female die (3) is provided with a cavity (300) and a first liquid conveying pipeline (51), and the cavity (300) penetrates through the upper end face of the female die (3). A liquid containingspace is formed inside the cavity (300), and the first liquid conveying pipeline (51) communicates with the liquid containing space. A plate pressing gap is formed between the edge pressing ring (2)and the female die (3), and the height of the plate pressing gap can be adjusted. The edge pressing ring (2) is provided with a center through hole, and the male die (1) penetrates through the centerthrough hole to reach the interior of the liquid containing space. The invention further provides a forming method with the revolving body part liquid-filling forming device applied. The molded surface of the male die and the molded surface of the female die are matched to shape the final molded surfaces of deep drawn parts so that the shaping effect of liquid-filling pressure can be partially replaced, liquid-filling pressure is effectively reduced, and the product dimension precision is improved.

Description

technical field [0001] The invention relates to a soft mold forming technology, in particular, to a forming device and a process for a rotary body, in particular to a liquid-filled forming device and a forming method for the rotary body. Background technique [0002] Variable-curvature revolving body parts (revolving body revolving body parts whose cross-section is composed of arcs of different radii) is an important core part of the power system of aerospace products. Its structural feature is the revolving body parts composed of different curvature radii. Satellites play an important role. Due to the variety of specifications, there are many specifications of forming molds required. At present, the aerospace field uses steel mold deep drawing technology for variable-curvature revolving parts. Due to the existence of suspended areas, this technology often leads to local instability of the sheet metal, resulting in wall thickness. Defects such as thinning or wrinkling affec...
