[CN 201711182209.4] Plate shearing method of hydraulic plate shearing machine
[CN 201711182209.4] Title of Plate Shearing Method for Hydraulic Plate Shearing Machine: Application Number of Plate Shearing Method for Hydraulic Plate Shearing Machine: CN 201711182209.4 Applicant: Anhui Donghai Machine Tool Manufacturing Co., Ltd. Application Date: 2017-11-23 Patent Type: Application for Invention The present invention discloses a plate shearing method for hydraulic plate shearing machine, belonging to the technical field of plate shearing machine. The shearing method of the hydraulic shearing machine of the present invention includes fast shearing, slow shearing, return and filling processes. The hydraulic system includes an oil pump, an oil tank, a main oil cylinder and an auxiliary oil cylinder, and also includes an electro-hydraulic reversing valve, Two-position three-way reversing valve and pressure relay, wherein the oil inlet of the oil pump is connected with the oil tank, and the oil outlet is connected with the upper cavity of the main oil cylinder, the port B port of the electro-hydraulic reversing valve and the pressure relay; the P port of the electro-hydraulic reversing valve is connected with the inner cavity of the auxiliary cylinder, its A port is connected with the lower cavity of the main cylinder, and its T port is connected with the oil tank; the P port of the two-position three-way reversing valve is connected with the oil pump The oil outlet is connected, and its B port is connected with the inner cavity of the auxiliary cylinder. By adopting the plate shearing method of the present invention, the circuit of the hydraulic system can be automatically switched according to the requirements of the plate to be shearing, so as to meet the shearing of different specifications of plate.
