The invention discloses a forming device for a neutral pole plate. The forming device for the neutral pole plate comprises a rack, a foam traction mechanism, a foam receding hole die cutting mechanism, an aluminum foil first die cutting mechanism, an aluminum foil paperboard secondary die cutting asynchronous repasting mechanism, a glue dripping optical fixation mechanism, a foam secondary die cutting mechanism and a shape die cutting structure, wherein the foam traction mechanism, the foam receding hole die cutting mechanism, the aluminum foil first die cutting mechanism, the aluminum foil paperboard secondary die cutting asynchronous repasting mechanism, the glue dripping optical fixation mechanism, the foam secondary die cutting mechanism and the shape die cutting structure are successively installed on the rack according to a production direction of single-pole and dual-pole neutral pole plates. The forming device disclosed by the invention has the beneficial effects that the wholeneutral pole plate is completed by one device, so highly integrated automatic production is completed, and efficiency and quality of production are increased; and quality differences and material waste caused by manual pasting are avoided.
