Abstract:
1. A toggling punch for attaching a waveguide entry spinning, including an elongated tubular body portion having a flange extending transversely from one end thereof, to a waveguide entry panel having an upper side, a lower side and a circular opening formed therein which is adapted to receive the tubular body portion extending upwardly therethrough so that the flange of the spinning is positioned at the lower side of the entry panel, comprising: a vertically disposed hydraulic cylinder having a cylinder body with a base end and a cylinder rod extending upwardly from said cylinder body and being movable between extended and retracted positions; said base end of said cylinder being fixed to a first support; a crimping assembly positioned on and secured to a second support which is positioned above said first support; said crimping assembly comprising: said base plate being larger than the diameter of said cylindrical crimping body so as to provide a supporting surface for the spinning flange and the entry panel thereon whereby said crimping pins, when moved to their said crimping positions, will outwardly deform said tubular body portion of the waveguide entry spinning above said waveguide entry panel to attach the waveguide entry spinning to the waveguide entry panel.
