The torque that is consumed in the deformation can be determined by the work done by the bending internal force and by the force equal to the external force on the upper roller. The upper roll on 3-roll plate bending machine is fixed. The total driving torque on the upper roller is: The calculation formula of driving power is: According to the actual application condition of the four-roll plate bending machine, the driving power of the driving roller is calculated during the pre-bending and rolling process, and the driving power of the main drive system is the larger value in the calculation result: Pq Driving power of the main drive system; PY The driving power of the driving roller when pre-bending; PJ The driving power of the driving roller when rolling circle. 0000008365 00000 n Therefore the calculation of the force analysis and driving power of the plate rolling machine is very important to the design of the roll bending machine. x]qF>wEIT'MyIoq&@ %%!_>cG/gS yoo~>}N=ko>MM_-O$^~{beFcGINF^J=>:_L7Wcj,B/o:&qYN}wh~YtZN5%~l:1hcGeiY'i]0[+PF ;^gtqu4 tEHTF;thO$Wk:RUzMUQ PnF~~yvqwI}og{^~>KY $},yuaGh/}qdat;;p1Q?O,yqyTIbB(1|Nprb;Giq|r= DESIGN CALCULATIONS The whole machine elements are.
