[CN201711329885.X] Pneumatic material support mechanism and control system of plate shearing machine and material support method


[CN201711329885.X] A Pneumatic Material Holding Mechanism and Control System and Material Holding Method of Plate Shearing Machine Title: A Pneumatic Material Holding Mechanism and Control System and Material Holding Method of Plate Shearing Machine Application Number: CN201711329885.X Applicant: Anhui Donghai Machine Tool Manufacturing Co., Ltd. Application Date: 2017-12-13 Patent Type: Invention Application The invention discloses a Pneumatic Material Holding Mechanism and Control System and Material Holding Method of Plate Shearing Machine, belonging to Plate Shearing. The pneumatic control system for the rear support of the shearing machine of the present invention includes a cylinder, a solenoid valve and a two-position solenoid valve, wherein the rod cavity of the cylinder is connected to the B port of the solenoid valve, and the rodless cavity passes through a one-way throttle valve on the one hand. The A port of the solenoid valve is connected to the B port of the two-position solenoid valve through a pipeline; the P port of the solenoid valve is connected to the air source through a pressure reducing valve and a quick connector. The pneumatic material support mechanism of the plate shearing machine of the present invention comprises a rear material support device and the above pneumatic control system. The technical scheme of the present invention can effectively reduce the gap between the material support plate and the worktable, so as to meet the use requirements of different lengths of plates to be cut, and at the same time can effectively prevent the plate from being twisted and deformed at the knife edge position to ensure the plate The shearing quality and accuracy.
