The advantages of the quick return mechanism:
"Many machine design applications need a difference in the average speed between the" forward "and" return "strokes.Overall, an external job is done through the link in the forward run, and the return stroke must Achieve as fast as possible so that there is a maximum time available for the work career Many fixes of the links will provide this feature The only problem is to synthesize the correct one ".
A rapid return mechanism is a device that converts circular movement (rotary motion following a circular path) into reciprocating movement (repetitive linear movement of round trip) in molding and molding machines, which are used to shape the stock of metal on flat surfaces. throughout the mechanical engineering. The quick return mechanism is the basis of the energy of these machines.
The mechanism consists of an arm attached to a rotating disk that moves at a uniform controlled speed. Unlike the crank, the mechanism arm operates at a different rate than the disc. By making the disk run at a different speed than the connected arm, productivity increases because the time needed for a cut is reduced. The design of this mechanism is specialized in the vectorial calculation and in the physical aspects of the kinematics (study of the movement without the effects of the forces) and the dynamics (study of the forces that affect the movement).
