Multi-station pull ring cover forming equipment and process with vertical turntable structure

The invention relates to the technical field of pull ring cover forming, and discloses a multi-station pull ring cover forming device and process of a vertical rotating disc structure. According to the device, a plurality of die position punch forming dies are evenly distributed in the circumferential direction of a main shaft, and each die comprises a lower die assembly, an upper die assembly and a material pressing piston; the lower die assembly moves up and down according to a designed track under the action of the lower die cam and the fan-shaped cam, and the upper die assembly moves up and down under the action of the upper end face cam and the cylindrical cam. According to the process, a special-shaped sheet material with scribed lines punched on the surface enters the equipment to be sliced, and in the revolution process along with a main shaft, the sheet material is drawn into a pull ring cover through shaping treatment in the up-down operation process of a lower die assembly and an upper die assembly
