2015-4-14 · For example, if a 5 pound hammer is swung at 50 feet per second, then the kinetic energy of the hammer is 5 * 50 * 50 / 64.32 = 194 foot pounds. If this then compresses a forging by 1/8 of an inch, then neglecting rebound, then it is about 194 * 96 or about 18,600 pounds of force on average. This is because 1/8" = 1/96th of a foot, and the ...

How much hydraulic pressure equals hammer blows?

 · One important thing to remember is that in a press, force is spread out over the surface areas of the dies, so that the bigger the die, the lower the PSI. We call it a "20 ton" press, or whatever, but that is really not the loading calculated for the surface area of the whole die.

Press versus hammer, kinetic energy vs pressure

 · At this point the hammer will bounce off the workpiece without changing its shape. This is the load limit of the hammer. This load limit is dependent on the type of hammer and work being done but for commercial forging hammers the ratio of hammer energy (kNm) to equivalent press force (tonne) is usually taken as somewhere between 1.5 and 3.5.
