An electric screw oil hydraulic press adopting composite oil cylinders for maintaining pressure comprises a base, stand columns mounted on the base, a cross beam mounted on the stand columns, a main motor mounted on the cross beam, a pinion mounted on an output shaft of the main motor, a main gear driven by the pinion, a screw rod, a nut, a slider, motor-reducer driving mechanisms, centering screw rods, tapered iron type link adjusting mechanisms, link mechanisms and the composite oil cylinders connected with the two link mechanisms, wherein the screw rod is mounted on the cross beam through an upper ball thrust bearing and a lower thrust bearing mechanism of the cross beam, the upper end part of the screw rod is mounted on the main gear, the nut is mounted at the lower end part of the screw rod, the slider is mounted on the nut and moves along guide rails of the stand columns, the motor-reducer driving mechanisms are mounted on side surfaces of the cross beam, the centering screw rods are mounted on the motor-reducer driving mechanisms and driven by the motor-reducer driving mechanisms to rotate, the tapered iron type link adjusting mechanisms are mounted on the centering screw rods, and the link mechanisms are connected onto the tapered iron type link adjusting mechanisms and the slider. According to the electric screw oil hydraulic press adopting the composite oil cylinders for maintaining pressure, the slider moves slowly, pressure-maintaining forming is realized, and the forming quality of a forge piece is good; the electric screw oil hydraulic press can be widely applied to a forging forming process of a workpiece.
Description
technical field [0001] The invention relates to a compound oil cylinder pressure-maintaining type electric screw oil press, which can be widely used in the forging and pressing forming process of workpieces. Background technique [0002] The existing electric screw forming machine has only the main screw transmission mechanism and no connecting rod pressure maintaining mechanism. During the forming process, the forging material cannot have enough time to fully flow and form, and the forming quality of the forging is poor. Contents of the invention [0003] The object of the present invention is to provide a compound oil cylinder pressure-maintaining electric screw hydraulic press when the forging is formed, the slider moves slowly, there is enough time for forging to maintain pressure, the forging material is fully flowed and formed, and the forging is of good quality. [0004] In order to achieve the above object, the compound oil cylinder pressure maintaining type electr...
