Abstract

The invention discloses a four-column hydraulic press and belongs to the field of metal forming machinery. The four-column hydraulic press comprises a machine base, stand columns, an upper beam, a movable beam and hydraulic cylinders, wherein the stand columns are fixedly installed on the machine base, the upper beam is fixedly installed on the top portions of the stand columns, the movable beam is installed on the stand columns in a sleeved mode, the hydraulic cylinders are fixedly installed on the upper beam, an output rod of each hydraulic cylinder is connected with the movable beam to drive the movable beam to move vertically along the stand columns, the hydraulic cylinders are connected with a plunger pump which is connected with a hydraulic control unit, and multiple pressure sensors are arranged on the machine base and are connected with the hydraulic control unit. According to the four-column hydraulic press, pressure information of the hydraulic press can be fed back to the hydraulic control unit, the hydraulic control unit regulates the pressure of the hydraulic cylinders quickly according to forming technological parameters, so that the pressure during the whole hydraulic process is controlled more accurately, and requirements of different technologies are met; the number of the pressure sensors is four, the four pressure sensors are arranged on four corners of the machine base, and pressure signals obtained through measurement are more accurate.

Description

[0001] technical field [0002] The invention relates to a hydraulic press, specifically a four-column hydraulic press, which belongs to the field of forging machinery. Background technique [0003] Four-column hydraulic press is a kind of mechanical equipment that uses the static pressure of hydraulic oil delivered by the oil pump to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing process and press forming process, such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet deep drawing, powder metallurgy, press fitting and so on. The conventional four-column hydraulic press realizes the transmission through the static pressure of the hydraulic oil delivered by the liquid pump, but in the actual working process, the pressure of the hydraulic press cannot be accurately grasped and controlled, which affects the pressing efficiency and quality of the hydraulic press.
