T type guide rail lifting cylinder rapid replacement device in forging machinery

The utility model discloses a lifting cylinder rapid replacement device of a T-shaped guide rail in metal forming machinery, which comprises a transversal guide rail and a longitudinal guide rail. Both the transversal guide rail and the longitudinal guide rail are mounted on a support seat, and the upper end surfaces of the transversal guide rail and the longitudinal guide rail are arranged on the same horizontal plane to be spliced into a groined shape; the transversal guide rail is provided with a broken part, a hydraulic oil cylinder is mounted on the support seat at the bottom of the broken part, and a lifting block is mounted on a piston of the hydraulic oil cylinder and is spliced and matched with the broken part. The lifting cylinder rapid replace device of the T-shaped guide rail in the metal forming machinery is characterized in that the lifting block is formed by splicing a plurality of components. Through the structural improvement of the lifting block, while a sealing ring of the hydraulic oil cyl
