[CN 201911245907.3] Energy-saving die forging hydraulic press and use method thereof


[CN 201911245907.3] An energy-saving die forging hydraulic press and its use method Title: An energy-saving die forging hydraulic press and its use method Application number: CN 201911245907.3 Applicant: Nanjing Hongqing Precision Material Technology Co., Ltd. Application Date: 2019-12-7 Patent Type: Invention Application The present invention discloses an energy-saving die forging hydraulic press and its use method, including a first base and a second base, one side of the first base is connected with one side of the second base, the left side of the top of the second base is fixedly connected with an equipment mounting frame, the top of the inner wall side of the equipment mounting frame is fixedly connected with a high-pressure pump through a connecting plate, and the bottom of the inner wall side of the equipment mounting frame is fixedly connected with a low-pressure pump through a connecting plate, which relates to the technical field of workpiece forging processing. The energy-saving die forging hydraulic press and its use method can detect the load on the flange in real time when forging the flange. When the load reaches 1.5-2MPa, the accumulator can automatically work. When the load reaches 20-30MPa, the accumulator can automatically stop working, so that the remaining hydraulic oil can be stored in the accumulator, which greatly reduces the loss of energy consumption and saves energy by 20%, at the same time, the automatic operation is convenient for the operator to use.
