Abstract

The utility model relates to an automatic pressing device for a chock type oil press. A chute type trunk piston oil pump 26 finishes the quantity of delivering oil by adjusting the angle of a trunk piston 5 through a rack 1, the feedback of oil pressure causes a high pressure piston 22 to move to drive a steel wire braking rope 12 to move and then drive a poking fork 8 to move, thus realizing the movement of the rack 1. A circuit control part is matched with a clock needle 34 electrode DZB and a constant-pressure switch DY to finish the pressure monitor of a whole oil pressing process.
