Multi-station synchronous near-net forming method and device containing space curved surface components

The invention discloses a multi-station synchronous near-net forming device containing space curved surface parts. The multi-station synchronous near-net forming device comprises a fixed base, a first stand column, a material adding module, a grinding and cutting material module, a laser material reducing module and the like. The gantry crane beam can move up and down relative to the gantry crane stand columns. The lower moving table can horizontally move relative to the lower moving table, the upper moving table can horizontally move relative to the fixed base, and the moving direction of the upper moving table is perpendicular to that of the lower moving table. The linkage cross beam rotates relative to the gantry crane cross beam; the material adding module and the material grinding and cutting module can synchronously and horizontally move relative to the linkage cross beam; the at least two first stand columns are arranged on the outer sides of the two ends of the workbench respectively and fixed above t
