[CN 201821165139.1] Charging valve installation structure of hydraulic press and hydraulic press
[CN 201821165139.1] A charging valve installation structure of a hydraulic press and a hydraulic press title: A charging valve installation structure of a hydraulic press and a hydraulic press application number: CN 201821165139.1 Applicant: Tianjin Zhiweitec Forming Technology Co., Ltd. Application Date: 2018-7-23 Patent Type: The utility model relates to the technical field of hydraulic presses, and specifically discloses a charging valve installation structure of a hydraulic press and a hydraulic press. The charging valve installation structure of the hydraulic press includes a charging valve, the charging valve is provided with a first oil hole communicating with the oil tank. The bottom of the main cylinder of the hydraulic press is provided with a containing groove and a through hole communicating with the containing groove. The containing groove is located above the through hole, and the charging valve is installed In the containing groove and below the beam, one end of the through hole communicates with the oil cavity inside the main cylinder, and the other end selectively communicates with the first oil hole. The charging valve can control the opening and closing of the first oil hole. By setting a containing groove on the bottom of the master cylinder and installing the filling valve in the containing groove, the installation hole on the cross beam is avoided, and the strength of the cross beam is ensured. At the same time, the filling valve is protected by the bottom of the master cylinder, and The steel consumption at the bottom of the main cylinder is reduced, and the equipment manufacturing cost is reduced.
