ABSTRACT:
A portable version of a honeycomb core forming restricter (20) for forming and shaping a workpiece made of stiff honeycomb core material, the apparatus (20) to be used in combination with a press including a male die (70) and a female die (72), the apparatus (20) including: (a) a base plate (62); (b) four support tower assemblies (24a, 24b, 24c, 24d) supported by the base plate (62); (c) two shafts (22a, 22b) supported by the support tower assemblies (24a, 24b, 24c, 24d), the shafts (2a, 22b) being arranged in a generally parallel relationship to each other and to the longitudinal axis of the female die 72; (d) a carrier sheet (74) for supporting the workpiece, the carrier sheet (74) being attached to the two shafts (22a, 22b); (e) four air motors (26a, 26b, 26c, 26d) for applying rotational torque to the shafts ( 22a, 22b); and (f) the support tower assemblies including a double acting air cylinder (36a) for moving the shaft (22a) in a transverse direction with respect to the longitudinal axis of the female die (72) and a pivoting mount (48a) for allowing the centerpoint of the shaft (22a) to move in an arc in a plane transverse to the longitudinal axis of the female die (72). A dedicated version of the honeycomb core forming restricter is also disclosed.
