[CN 201720808609.0] Hydraulic electric control device on numerical control hydraulic guillotine shearing machine
[CN 201720808609.0] A hydraulic electric control device on a CNC hydraulic guillotine shearing machine Title: A hydraulic electric control device on a CNC hydraulic guillotine shearing machine Application number: CN 201720808609.0 Applicant: Maanshan City Christie Forging Machine Tool Factory Application date: 2017-7-5 Patent type: Utility model The utility model relates to the field of shearing machines, specifically to a hydraulic electric control device on a CNC hydraulic guillotine shearing machine, including a fixed black box, two threaded cylinders are arranged vertically and symmetrically upward on the central line of the inner bottom of the fixed dark box. Adjusting screws are installed in the threaded cylinders, positioning nuts are fixed on the adjusting screws, the fixing plate is fixed between the positioning nuts and the nuts of the adjusting screws, and the bottom surface of the fixing plate is fitted with the positioning nuts. The front, back, left and right sides and the bottom surface of the fixed dark box are evenly provided with several ventilation holes, and the center of the inner bottom surface of the fixed dark box is fixed with a cooling fan with a driving motor, and the inner side wall of the fixed dark box is fixed with a temperature sensor and a central processing unit. The central processing unit is electrically connected to the temperature sensor and the cooling fan respectively; A heat dissipation channel is formed between the holes and the external environment, and the heat dissipation fan will accelerate the circulation of the fixed dark box and the outside air, thereby effectively cooling, thereby effectively extending the service life of the electronic control components.
