Steel Forging Hammers

Heavy industrial machinery which have reciprocating, impact, rotating masses and other machinery generating dynamic loads like crushers, hammers, punch presses often need a machinery support system that can resist dynamic forces and the resulting vibrations. It may be elastomeric isolators, large inertial mass, steel coil springs and viscous fluid dampers or a varied combination of these.
Forging Hammers, Punching machines, Metal Forming Presses and other types of shock producing machines generate powerful short-period impact loads, characterised as shock pulses. Only a part of the shock energy is utilised in the intended hammering, punching, pressing, shaping operations and the rest is dissipated in the foundation causing intense vibration.
The pre-impact kinetic energy of the ram converts to post-impact kinetic energy of the entire machine, forging hammer etc. making it oscillate.
Shocks from hammer foundations transmit to the soil and surroundings causing horizontal soil vibrations that may induce resonant building oscillations while ground vibrations that are transformed in series of harmonic waves with the predominant frequency equal to the frequency of vertical vibrations of the source.
This, oscillation has to be arrested or sufficiently decayed before the next impact.
These excessive-machine-generated-vibrations, are detrimental to:
1. The proper operation of the machinery installations, technological systems, and other workshop components.
2. Cause damage / enhance maintenance cost of the building and the structures, dynamic settlements of column footings, where the machinery is installed.
3. Generate waves, high amplitude impact shock pulses and noises that transmit to the environment, affecting the foundations of sensitive installations and equipment, besides causing discomfort / fatigue for the workshop personnel. In India, operation of large impact machines (like Mechanical presses, Forging Hammers, Punch presses , etc.) with very high dynamic load
