All metal forming operations -Blanking, Drawing or Forming on
the press produce very large impact forces.These forces travel through the press frame
into the foundation. The foundation produces a rebound force equal to the
impact force and this travels inside the machine. These internal forces are
produced by the stamping operation on a press when the press is bolted to a
foundation or installed on isolators. However, the magnitude of the vibration
within the press is lower when using vibration isolators. Bolting the press
rigidly to a foundation subjects it to more vibration and impact force.
Vibration isolators are cushions that transform a sudden shock pulse into a
decaying series of longer duration forces. Imagine the force of hitting a wall
with our fist. Now hitting the wall with the same energy, but with our hand in
a boxing glove. It is obvious that the later hurt less! This is because the
impact duration is longer, effectively reducing the impact force. Short
duration impacts mean higher force.
This same thing happens on a press rigidly bolted to the foundation. The sudden release of potential energy at impact causes the press foot to slam against the foundation. This fast duration, high magnitude force hits the foundation and the foundation responds in kind, sending damaging forces back into the press. In case the press is isolated from the foundation with Dynemech passive vibration isolators, the isolators will absorb most of the impact energy of the blow. Now, the impact force at the foundation is reduced and also the rebound force transmitted by the foundation into the press machine
