[CN201810999724.X] Two-way press for hard alloy production and pressing


[CN201810999724.X] Title of a two-way press for hard alloy production and pressing: Application number of a two-way press for hard alloy production and pressing: CN201810999724.X Applicant: Gao Fancheng Application date: 2018-8-30 Patent type: Invention application The present invention discloses a two-way press for hard alloy production and pressing, it comprises a vertical plate, a top mounting plate fixedly installed at the upper end of the side surface of the vertical plate, a middle mounting plate fixedly installed at the middle of the side surface of the vertical plate, and a bottom plate fixedly installed at the lower end of the side surface of the vertical plate. An upper hydraulic cylinder and a hopper are fixedly installed vertically on the upper surface of the upper hydraulic cylinder, and an upper mold is fixedly installed vertically on the lower piston head of the upper hydraulic cylinder. The beneficial effect is that the two-way press for cemented carbide production and pressing according to the present invention can simultaneously press the cemented carbide powder up and down, so the pressure attenuation generated in the height direction of the compact is small and almost negligible. Therefore, the weight and density of the compact at the unit height are the same, thereby realizing equal density pressing, effectively ensuring that the height of the compact is consistent with the set height, and has good practicability.
