The present invention relates to the high-end equipment manufacturing industry, and specifically relates to a hot die forging lever type heavy-duty forging force automatic and precise control device and method, including a lever, a guide rail, an anti-heavy-load sliding beam, a lever fulcrum seat, a power unit and a locking unit. There is a fulcrum chute in the middle of the lever, and a self-lubricating copper guide rail sleeve is installed in the fulcrum chute; the two ends of the anti-heavy-load sliding beam are connected to the lever fulcrum seat in rotation, and the middle part is in contact with the self-lubricating copper guide rail sleeve surface and slidingly connected, and the lever fulcrum seat The upper end is connected with the guide rail; the power unit drives the lever fulcrum seat to move along the guide rail and the fulcrum chute; the locking unit locks the lever fulcrum seat on the guide rail. On the basis of lever-type mechanical lower forging force synchronization, symmetry and balance, and large ejection force, it can effectively improve efficiency, ejection force (more than 5 times higher than traditional technology), and stability, and meet the needs of precision multi-station hot-touch forging and The automatic control requirements of the net near forming process of its automatic line can achieve the effect of automatic and precise adjustment and control of heavy-duty forging extrusion force.
