[CN 201811146846.0] Hydraulic control plate shearing process of plate shearing machine
[CN 201811146846.0] Title of Hydraulic Control Plate Shearing Process for Plate Shearing Machine: Application Number of Hydraulic Control Plate Shearing Process for Plate Shearing Machine: CN 201811146846.0 Applicant: Anhui Donghai Machine Tool Manufacturing Co., Ltd. Application Date: 2018-9-29 Patent Type: Application for Invention The present invention discloses a Hydraulic Control Plate Shearing Process for Plate Shearing Machine, belonging to the technical field of forging machine tools. In the shearing machine hydraulic system of the present invention, the oil outlet of the first oil pump and the oil outlet of the second oil pump are respectively connected to the P port of the first electro-hydraulic reversing valve and the P port of the second electro-hydraulic reversing valve through pipelines., The lower cavity of the shearing cylinder, the lower cavity of the pressing cylinder, the first accumulator and the second accumulator are connected, and the port of the first electro-hydraulic reversing valve is connected with the upper cavity of the shearing cylinder, the B port is directly connected with the upper chamber of the shearing cylinder through the pipeline; the port of the second electro-hydraulic reversing valve is connected with the upper chamber of the pressure cylinder through the second hydraulic control check valve, and the B port is directly connected with the upper chamber of the pressure cylinder through the pipeline. The invention optimizes the design of the hydraulic system of the shearing machine, which can effectively improve the processing efficiency of the shearing machine, effectively reduce the vibration of the machine tool and protect the blade, and is beneficial to prolong the life of the blade.
