[CN 201611157135.4] Balancing device for open crank press
[CN 201611157135.4] Title of Balancing Device for Open Crank Press: Application Number of Balancing Device for Open Crank Press: CN 201611157135.4 Applicant: Jiangsu Wode Electromechanical Group Co., Ltd. Application Date: 2017-4-21 Patent Type: Application for Invention The present invention discloses an balancing device for open crank press, which includes two groups of balancing cylinders, transition joints and curved rods symmetrically arranged on both sides of a sliding block and arranged in a straight line from top to bottom, the lower end of each balance cylinder is vertically fixed on the top of the fuselage of the open crank press through two support seats, the piston rod head of the balance cylinder passes through the top plate of the fuselage and is fixedly connected with the upper end of the transition joint, the lower end of the transition joint is hinged with the upper end of the curved rod through the upper hinge pin, the upper part of the curved rod is sleeved on the corresponding crankshaft journal, and the lower end of the curved rod is fixedly connected with the corresponding side plate of the slider. The invention solves the problem of installation and maintenance of the balance device of the open crank press with the crankshaft arranged horizontally, and can prevent the impact and noise generated when the slider is lowered. Eliminate the gap between the connecting rod and the slider, and reduce the impact and wear of the stressed parts. The power consumption of the mold height adjustment mechanism is reduced, and at the same time, accidents caused by the slider falling when the brake fails or the connecting rod is broken can be prevented.
