[CN 201710533249.2] Hydraulic press with buffer and slider weight balance
[CN 201710533249.2] Title of a hydraulic press with buffer and slider weight balance: Application number of a hydraulic press with buffer and slider weight balance: CN 201710533249.2 Applicant: Jiangsu Guoli Forging Machine Tool Co., Ltd. Application Date: 2017-7-3 Patent Type: Invention Application The present invention relates to a hydraulic press with buffer and slider weight balance, including left and right upright posts and an upper beam, with a plunger cylinder installed in the center of the upper beam, the left and right sides of the plunger cylinder are equipped with master cylinders, the lower ends of the master cylinder and the piston of the plunger cylinder are connected with the slider, the left and right ends of the upper beam are symmetrically equipped with composite oil cylinders, the upper end of the composite oil cylinder body is open, the inner cavity of the composite oil cylinder body is equipped with a composite oil cylinder piston, the center of the composite oil cylinder piston is connected with a downward extending composite oil cylinder rod, and the lower end is extended from the center, the lower end of the composite cylinder piston rod is screwed with a composite cylinder buffer block; the left and right sides of the slider are symmetrically connected with buffer stops extending to the outside, and the buffer stops are respectively suit at the lower part of the composite cylinder piston rod and located above the composite cylinder buffer block. The composite cylinder of the hydraulic press can realize the buffer function, and can participate in the fast return movement of the slider when the buffer function is not needed.
