Design And Study Of The Tilting And Leading Manipulator

On the basis of the development and the actuality of hydraulic tilting and leading manipulator, this paper analyzes and studies for the main problems that exist on the original tilting gear of section steel works, Chongqing iron and steel company, develops a hydraulic tilting and leading manipulator that does suit the operation of the production line. Its structure is simple, its manufacture easy, its production cycle short, its action agile, its adaptability strong, its technique advanced, the adjustment and the control of its parameters easy, its maintenance convenient, and its operation simple.This paper discusses how to design the hydraulic tilting and leading manipulator, therein the operating principle, the major structure, the hydraulic system and the control system of the hydraulic tilting and leading manipulator are analyzed in detail, the main performance parameters are calculated, and the dynamic performance of hydraulic system is analyzed. In mechanical structure, the old clamper is improved. The open width of the improved parallel smooth-acting straight camper is not only large but also adjusted. During work, the clamp roll and the tilting roll turn around a fixed point along the same direction and don't interfere each other, and have enough clamp force and enough tilting moment. The replace of the old mechanical tilting mill makes the structure of the complete tilting equipment be compact, the weight light, the hydraulic system prone to realize automation. Composed of the hydraulic system and the automatic control system, the electro-hydraulic system exerts fully the merits of the hydraulic tilting and leading manipulator.From the time that the equipment tested run, the improved hydraulic tilting and leading manipulator overcome basically the disadvantages of the old equipment, such as the uncertainty of clamper tilting, the bad adaptability, the low efficiency and the large energy consumption, also cut largely down the amount of equipment maintenance, and reduced the labor intensity of worker. It made the success ratio of tilting stock one time be enhanced, realized the tilting of round steel, made the angle deviation, which stock comes into pass, be small, reduced stock's phenomena, such as the torsion, the off-square, the stagger, and so on, and finally improved the product quality.The system passed the project checking and accepting organized by Chongqing iron and steel company, and the experts attending the checking and accepting meeting paid the higher evaluate for the practicability and the advanced capability of the system.
