Abstract
The invention belongs to the technical field of hydraulic machine manufacturing and particularly relates to a servo motor assisted redundancy guide unbalance loading resistant horizontal servo hydraulic cylinder. A guide shaft is connected with a servo hydraulic cylinder through a connecting sleeve and a guide shaft seat; the guide shaft is parallel to the servo hydraulic cylinder; a deep hole isformed in a rear section of the guide shaft; a rear end of the guide shaft is connected with a ball screw nut through a guide shaft flange, a front end of a ball screw is arranged in the deep hole, the ball screw is connected with a servo motor through a screw-servo motor connecting flange, the servo motor is fixedly arranged on a motor supporting frame, and the motor supporting frame is fixed toa working equipment rack. According to the horizontal servo hydraulic cylinder, the servo motor is additionally arranged to drive the guide shaft, the guide shaft is connected with a piston rod of theservo hydraulic cylinder, and through redundant guide supports, the rigidity of the horizontal servo hydraulic cylinder is improved, the stress state of the piston rod is improved, and the unbalanceloading resistance of the horizontal servo hydraulic cylinder is improved.
Description
technical field [0001] The invention belongs to the technical field of hydraulic machinery manufacturing, and in particular relates to a redundant-guided anti-offset horizontal servo hydraulic cylinder assisted by a servo motor. Background technique [0002] Shearing machine is an important core equipment on the finishing line of medium and heavy plates. With the continuous increase of steel plate thickness and continuous improvement of steel plate strength, traditional shearing technology restricts the improvement of shearing dimensional accuracy and section quality requirements of wide and thick plates. Compared with the general oblique blade cutting technology, the rolling shear technology has the advantages of good cutting quality, large cutting thickness, less scratch and wear of the cutting blade, straight cutting steel plate, and high cutting efficiency. Therefore, it is widely used in the medium and thick plate finishing line. A rolling shear driven by a horizontal ...
