Types of Forging Processes
The operation principle of a power-drop hammer is similar to that ofan air-drop hammer. In the down stroke, in addition to gravity,the ram is accelerated by steam, cold air, or hot air pressure. In the power-drop hammer, the acceleration of the ram is enhancedwith air pressure applied on the top side of the ram cylinder.
