<p>The power stroke of the within punch press results from the electrical interaction of an armature, attached in depending relation from a superposed positioned die set, and a solenoid coil located in the supporting base of the press. In assembling each component of the sub-assemblies consisting of the supported die set and of the supporting base, a positional relation is achieved for each component which in the assembly of the die set onto the base contributes to a proper projected positioning of the armature within the encircling solenoid coil, to thereby achieve the required electrical reaction therebetween without losses or other inefficiencies.</p> |
