[CN 202210591255.4] Title of New Powder Hydraulic Press: Application Number of New Powder Hydraulic Press: CN 202210591255.4 Applicant: Chengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd. Application Date: 2022-5-27 Patent Type: Application for the Invention The present invention discloses a new powder hydraulic press, which belongs to the technical field of hydraulic press and includes a frame, a feeding mechanism and a powder mold therein. The feeding pipe of the feeding mechanism is arranged on the side of the powder mold for conveying powder raw material into the powder mold; the mold is arranged in the mold rack, and the hydraulic assembly in the frame is used to press the powder and drive the mold rack and the powder to move at a low speed in the same direction. By adding a bypass oil path between the rod cavity of the main oil cylinder and the rod cavity of the medium-female floating cylinder, and setting a master cylinder pressing reversing valve on the bypass oil path, the rapid descent of the main oil cylinder and the reversing of pressing powder are realized, and the hydraulic oil in the rod cavity of the main oil cylinder is evenly distributed to the rod cavities of the two medium-female floating cylinders, thus realizing the pressure and movement speed adjustment of the main oil cylinder and the medium-female floating cylinder, greatly improve the yield of the product.
