[CN 201621098083.3] Hydraulic Overload Protection System for Automatic Forging Press
[CN 201621098083.3] Title of hydraulic overload protection system for a directional automatic forging press: Application number of hydraulic overload protection system for a directional automatic forging press: CN 201621098083.3 Applicant: Anhui Anyi Machinery Co., Ltd. Application date: 2016-9-30 Patent Type: Utility Model The utility model relates to the technical field of directional forging hydraulic presses, in particular to a hydraulic overload protection system for a directional automatic forging press; it comprises a pneumatic unloading valve, a pneumatic pump, a normally open two-position two-way solenoid valve, a normally closed two-position three-way solenoid valve and a pressure stabilizing device. The pneumatic pump is connected to the pneumatic unloading valve through a pipeline. The pipeline between the pneumatic pump and the pneumatic unloading valve is sequentially provided with an oil filter and a one-way valve, and the pneumatic unloading valve and the hydraulic pad are connected through a pipeline. The hydraulic overload protection system of the facing automatic forging press disclosed by the utility model has the advantages of high protection accuracy and automatic recovery of the original protection function after the overload is solved due to the pneumatic overload protection device.
