Design, Simulate and study the hydraulic rectifier circuit used in Pipe$-$bending

machine

A rapid$-$traverse$/$feed circuit is to be developed for a universal bending machine. The working

speeds of the hydraulic cylinder must be adjustable. The speed for the rapid traverse is adjusted by

means of a throttle valve. After a specified travel distance, the bending operation must be executed

independently of load $($feed motion$).$ A flow control valve should be used for this purpose. The

return stroke over the same distance should be controlled by the same valve. The circuit should be

assembled in such a way that hydraulic fluid passes through the flow control valve in the same

direction during the feed motion and return stroke. The return stroke back to the starting position

can be executed without a throttle function.
