Abstract

The invention discloses a special-shaped component ultra-low-pressure liquid filling forming system which comprises a control system, a supercharger, a driving device, a pre-forming unit and a final forming unit. The invention further provides a special-shaped component ultra-low-pressure liquid filling forming method based on the special-shaped component ultra-low-pressure liquid filling formingsystem. The special-shaped component ultra-low-pressure liquid filling forming method comprises the following steps that S1, a slab is adopted to make an equal-diameter cylinder-shaped roll blank witha lap joint part in the longitudinal direction; S2, the equal-diameter cylinder-shaped roll blank is bulged into a variable-diameter cylinder-shaped prefabricated roll blank; S3, the lap joint part reserved on the variable-diameter cylinder-shaped prefabricated roll blank is cut and welded in the axis direction to obtain a variable-diameter prefabricated pipe blank; and S4, the variable-diameterprefabricated pipe blank is subjected to fluid filling shape pressing, so that the variable-diameter prefabricated pipe blank is subjected to compression deformation, and a special-shaped component isformed. According to the special-shaped component ultra-low-pressure liquid filling forming system and method, the performance, forming precision and forming efficiency of the special-shaped component are improved.

Description

technical field [0001] The invention relates to the technical field of metal forming and manufacturing, in particular to an ultra-low pressure liquid-filled forming system and method for special-shaped components. Background technique [0002] With the continuous development of high-tech industries such as automobiles, aviation and aerospace, more stringent requirements are put forward for the lightweight, integrated, high performance and high reliability of the structure. It is necessary not only to ensure the overall reliability of the structure, but also to ensure that the weight is as light as possible on the basis of meeting the strength requirements, and to obtain high-precision shape dimensions and excellent performance on the premise of meeting the structural requirements. As a typical structure, special-shaped thin-walled metal pipe components often have the characteristics of complex shape, large diameter-thickness ratio, large cross-sectional difference and high m...
