[CN 202010805606.8] Repeated positioning system for hydraulic press
[CN 202010805606.8] Title of a Hydraulic Press Repeated Positioning System: Application Number of a Hydraulic Press Repeated Positioning System: CN 202010805606.8 Applicant: Yao Xiaofang Application Date: 2020-8-12 Patent Type: Invention Application The present invention relates to a hydraulic press repeated positioning system, including an upper limit block, a lower limit block and a limit plate. The limit plate is located between the upper limit block and the lower limit block, and the movable block is arranged below the limit plate, the lower limit block is movably installed in the fuselage and moves in and out of the fuselage laterally relative to the fuselage. A linkage mechanism is arranged between the movable block and the lower limit block. During the downward movement, the lower limit block is driven by the linkage mechanism to move from the inside of the fuselage to below the limit plate. The invention prevents the dust generated during blanking from accumulating on the lower limit block and affecting the position accuracy of the lower dead center of the slider through the movement of the lower limit block in and out of the fuselage, and the impact of the slider on the lower limit block acts on the wedge The block reduces the impact and damage to the adjusting screw, ensures the position accuracy of the lower limit block, and further ensures the position accuracy of the lower dead center of the slider.
