[CN 201721124704.5] powder metallurgy hydraulic press


[CN 201721124704.5] Title of Powder Metallurgy Hydraulic Press: Application Number of Powder Metallurgy Hydraulic Press: CN 201721124704.5 Applicant: Ruian Huada Hydraulic Machinery Factory Application Date: 2017-9-4 Patent Type: Utility Model The utility model discloses a powder metallurgy hydraulic press, including a top plate, a bottom plate, an intermediate plate and an upright column. The top plate and the bottom plate are fixedly connected by the upright column. The intermediate plate is pushed by a main oil cylinder below the top plate to move up and down, the main oil cylinder is installed on the top plate, the bottom surface of the middle plate is fixedly installed with a forming upper die, and the top surface of the bottom plate is fixedly installed with a forming lower die. The forming lower die has an inwardly recessed forming die cavity. The forming upper die enters the forming die cavity during pressing. The characteristic is that the bottom end surface of the forming upper die is provided with an upper steel plate and fixedly installed with a high-temperature resistant magnet. The upper steel plate is magnetically adsorbed on the bottom end surface of the forming die; when the forming die leaves the forming die cavity after the workpiece is pressed, the magnetic adsorption force between the upper steel plate and the high temperature resistant magnet is less than the adhesion force between the upper steel plate and the workpiece. The utility model is used for the pressing of powder metallurgy workpieces, which can prevent sticking of materials and dust, improve efficiency and better ensure the quality of workpieces.
