Mechanism for Catching Workpieces in Presses

The mechanism is used for case when the workpiece is jammed with the punch after being pressed and then removed at upper position of the blue slider (removing device is not shown). Green gutter catches the workpiece and guides it out of the pressing area. The gutter moves aside when the punch goes down.
Blue slider, yellow conrod and green cranks to which the green gutter is fixed, create a slider crank mechanism.
