Plate Structure Improvement And Simulation Analysis Of Tipper

In the process of rolling, plate tipper are important factors influencing the surface quality of slab, plays flip, the transport role. Steel in the process when the arm is going to steel plate placed on the platform, will continue to be down-5 °, this leads us to the steel claw in steel pusher forward phenomenon occurred during the arm downward, sliding steel, slab surface scratches which can influence of slab quality. In view of sliding steel issues, steel arm to improve the structure of the simulation analysis to verify its performance. Paper first according to in the thick Board turned steel machine of basic parameter, through VB programming software on its main parts for has strength calculation; second for site sliding steel phenomenon, on main parts steel arm for structure improved, will original steel arm of Shang surface raised 5 °, and of vertical of surface left partial 5 °, and steel arm keep vertical, dang institutions downward 5 ° Shi, steel arm just and platform keep level, thus achieved billet of smooth flip, not appeared because steel claw of pushed steel and makes billet designated hurt of phenomenon. Using of finite element software ANSYS Workbench spindle and stress-strain analysis of improved steel arm. Through on steel arm for 0 °, 45 °, 90 ° of stress analysis, get stress images, analysis stress images obtained, steel arm in 0 ° Shi by by static stress maximum, compared maximum stress and material of yield limit, validation improved Hou of steel arm strength meet requirements; analysis strain images can obtained maximum General deformation volume and the occurred deformation of main parts, compared maximum deformation and original structure pieces of differences, its numerical far is less than steel arm of length, can think not by effects, improved Hou turned steel machine steel arm of stiffness meet requirements. Through structural improvements, avoids sliding steel slab surface scratches this phenomenon of the last spindle and improved in order to prevent the steel arm resonance phenomena, as far as possible away from the resonance region and spindle to tipper and modal analysis of modified steel arm to determine the natural frequency, avoiding tipper resonance phenomenon occurs while in use.
