[CN 202210157181.3] Method for Quickly and Accurately Determining the Center Position of Upper Hinge Point of Double Cylinder Rear Pull Hydraulic Press
[CN 202210157181.3] Method for quickly and accurately determining the center position of the upper hinge point of the double-cylinder rear-pull hydraulic press Title: Method for quickly and accurately determining the center position of the upper hinge point of the double-cylinder rear-pull hydraulic press Application Number: CN 202210157181.3 Applicant: China Electric Construction Group Guiyang Survey and Design Institute Co., Ltd. Application Date: 2022-2-21 Patent Type: Invention Application The invention discloses a method for quickly and accurately determining the center position of the upper hinge point of the upper hinge point of the upper hinge point of the upper-pull hydraulic press of the double-pull, the intersection point of the two circles is used as the coincidence point to satisfy the running trajectory of the two circular moving points, when the radial gate is fully closed, the center of the lower crane head of the hydraulic press is taken as the center of the circle, the distance from the center of the lower crane head of the hydraulic press to the center of the upper crane head of the hydraulic press or the center of the middle supporting hinge is taken as the radius R1, and when the radial gate is fully opened, the intersection point P1 of the circular trajectory from the center of the lower crane head of the hydraulic press to the upper crane head of the hydraulic press or the center of the middle supporting hinge is taken as the radius R2 the central location, in this way, the center position of the upper hinge point of the double-cylinder rear-pull hydraulic press can be quickly and accurately determined, the work efficiency is effectively improved, the force arm of the oil cylinder will not be reduced, the opening and closing torque is the same as the design value, and the safety of the opening and closing of the radial gate remains unchanged, which effectively guarantees the safety of the operation of the radial gate.
