THEORY OF OPERATION:
The operator loads a blank onto PS 50, locks the parts in place with pneumatic grippers, and sets the feed in motion which automatically triggers a shear, punch or stamping machine.
PS 50 advances the material towards the shear blade or punch in increments automatically triggering the secondary machine. When complete, the system retracts for removal and loading of the next piece.
Side-to-side adjustable pneumatic fingers grip the work-piece for feeding. Grippers can be placed up to 5 ft. apart and travel up to 49” front to rear. Gripper can move to within 1” of the punch or shear blade. 3/16” dia. pins on each gripper fit into a corresponding hole on the blank for accurate referencing.
Rugged 1” dual ball screws and (4) ¾” shafts handle the sheet movement. A 1000 watt closed loop D.C. servo motor/amplifier drives the system with speed and precision. Travel is 49”.
Gauging from the front of the device using one reference point on the work-piece eliminates cumulative tolerance buildup experienced with backgauging. All dimensions will be within ± .002” of the original reference. |
