6. Parts of Mechanical Press Fly Wheel : The flywheel is mounted at the edge of the driving shaft and is connected to it through a clutch. Clutch : The clutch is used for connecting and disconnecting the driving shaft with the flywheel when it is necessary to start or stop the movement of the ram. Brakes: The brakes are used to stop the movement of the driving shaft immediately after it is disconnected from the fly wheel

7. Parts of Mechanical press Driving mechanism : The rotary movement of the motor is converted into the reciprocating movement of the ram by crank and connecting rod, eccentric and connecting rod in mechanical presses Ram : Ram reciprocates to and fro within its guide ways with prescribed stroke length and power. Ram at its bottom end carries punch to process the work piece. Pitman : It is the part which connects the ram and crankshaft or ram eccentric.

8. Applications of hydraulic Press Power presses are used for punching or stamping, forming or drawing and embossing operation. Press brakes are used for bending operations. Press working is used in large number of industries like automobile industry, aircraft industry, telecommunication electrical appliance, utensils making industry are major examples
