Molding device and molding method for preparing Ti/AI powder body blade

Discloses is a molding device and a molding method for preparing a Ti/AI powder body blade, and the molding device and the molding method for preparing the Ti/AI powder body blade belong to the technical field of powder molding processes. The molding device and the molding method for preparing the Ti/AI powder body blade solve the problems that a blade part is difficult to mold in a traditional processing technology due to the fact that a TiAI based alloy is poor in plasticity, big in deformation resistance and high in deformation temperature. The device scheme for preparing the Ti/AI powder body blade includes: a split ring type lower model and a split ring upper model are arranged in a reinforcing sleeve from the bottom up, the split ring upper model and the split ring type lower model are both matched with the reinforcing sleeve in a slide mode and constrained by the reinforcing sleeve, a lower model plunger chip is installed in the split ring type lower model and matched with the split ring type lower model in the slide mode, and one end of a upper model plunger chip is arranged in the split ring upper model and matched with the split ring upper model in the slide mode. The method scheme for preparing the Ti/AI powder body blade includes: processing lubrication and blending powders, preparing a Ti/AI powder preformed blank, and forging and molding a Ti/AI powder precisely. The molding device and the molding method for preparing the Ti/AI powder body blade are used for the Ti/AI powder body blade molding.
