ABSTRACT:
A punch machine having reduced effects of reaction forces. An apparatus is provided which divides the overall structure into two cooperating structures, one for transmitting a working (or reaction) force, and the other for maintaining the alignment between the workpiece and tool components. The apparatus includes a pair of tools movable toward and away from each other along a tool movement axis, a base or frame, tool support-and-guide components fixed on the base, components for moving and positioning a workpiece in a specified plane perpendicular to the tool movement axis, and reaction force transmitting components pivotally joined to the tool support-and-guide components.
