[CN 201821695727.6] Hydraulic system and metal shearing machine
[CN 201821695727.6] Title of a Hydraulic System and a Metal Shearing Machine: Application Number of a Hydraulic System and a Metal Shearing Machine: CN 201821695727.6 Applicant: Changsha Zhongjin Intelligent Equipment Co., Ltd. Application Date: 2018-10-18 Patent Type: Utility Model The utility model proposes a hydraulic system for a metal shearing machine, including a hydraulic pump and several synchronous shear cylinders, the shear cylinder at least includes a first shear cylinder and a second shear cylinder, the first shear cylinder is communicated with the hydraulic pump through a first pipeline, and the first pipeline is further provided with a plurality of cartridge valves; the second shear cylinder is connected with the hydraulic pump through a second pipeline, and the second pipeline is also provided with a plurality of cartridge valves, the cartridge valves on the first pipeline include a second cartridge valve, and the cartridge valves on the second pipeline include a third cartridge valve. The hydraulic system of this configuration includes at least a first shear cylinder and a second shear cylinder. The metal shearing machine adopting the above hydraulic system has a relatively simple structure. When shearing metal, the first shearing cylinder and the second shearing cylinder can provide power at the same time, and the shearing force is greater, the shearing speed is faster, and the shearing efficiency is higher, and the use cost is lower. The utility model also provides a metal shearing machine.
