[CN 201620669896.7] Rotary mobile hydraulic press and its ram ejection hydraulic mechanism


[CN 201620669896.7] Title of a rotary mobile hydraulic press and its ram ejection hydraulic mechanism: Application number of a rotary mobile hydraulic press and its ram ejection hydraulic mechanism: CN 201620669896.7 Applicant: Anhui Donghai Machine Tool Manufacturing Co., Ltd. Application Date: 2016-6-28 Patent Type: Utility Model The utility model discloses a rotary mobile hydraulic press and its ram ejection hydraulic mechanism, belonging to the technical field of hydraulic presses. The ram ejection hydraulic mechanism of the rotary mobile hydraulic press of the utility model includes a main hydraulic station, a main oil cylinder and a guide column. The plunger plate of the main oil cylinder is hoisted with a ram seat through a ram connecting plate. The ram connecting plate and the inside of the ram seat are provided with a ram ejection cylinder. The guide column is processed with an oil passage process hole along its length, and the main hydraulic station is connected with the oil passage process hole through an oil pipe, the oil is supplied to the pressure head ejection cylinder through the oil passing process hole. The utility model is through the processing of the oil passing process hole in the guide column, so as to facilitate the oil supply for the pressure head to push out the oil cylinder, and prevent the unsafe and unsightly problem of the oil pipe exposed outside.
