Quick Return Mechanism

A rapid return mechanism serves as a device that transforms circular motion into reciprocating motion, primarily employed in presses and shaping machines designed for molding metal stocks into flat surfaces. This mechanism finds extensive application in shaping machines, slotting machines, and rotary internal combustion engines. The term “quick return” signifies that the return stroke occurs at a higher speed than the forward stroke, facilitating swift retrieval of the tool after completing a specific task. Quick-return mechanisms exhibit distinct input durations for their working and return strokes. The time ratio of a quick return mechanism represents the ratio between the change in input displacement during the working stroke and its change during the return stroke.
