Coining Press

    0.01 sec.
Coining Press 

a short-stroke, vertical knuckle-joint press designed for coining and other closed impression die forging operations. A distinguishing feature is the use of a crank-and-toggle mechanism to drive a slide, in which the upper link of the toggle is connected to the frame of the press and the lower link is connected to the slide block. Such a mechanism develops great force on the slide block at the end of the working stroke for a small torque at the driving crankshaft. Coining presses may develop pressures up to approximately 40 meganewtons (4,000 tonsforce).
