Abstract: Automatic guides for positioning and aligning sheet material to be cut in which the guides carry elements to control a drive, which can be set to advance and retract and partially rotate the guides to required positions.
Abstract:
The object of the present invention is to provide improvements for machines of this kind, and more particularly to the guide edges; these improvements consist of automatic means for positioning the guide edges in such fashion as to enable the production of sequences of at least two cuts in different positions. Another object of the present invention is to provide for the operation of the cutter to be subject to the proper positioning of the item being cut in relation to the guide edges; this positioning is achieved by pneumatically or hydraulically operated means. Another object of the present invention is to provide a pair of guide edges with means slidable in appropriate guides on the machine bed, means for articulating said guide edges, means for controlling the reciprocating movements of each guide edge in a coordinated way; with the said guide edges at their ends, containing electrical means or devices, for controlling the cutter.
Claim:
In a machine for cutting sheet material, metal sheet and the like, the combination comprising a machine bed to support said sheet material, metal sheet and the like, a vertically reciprocable slide, cutter means carried by the slide, said cutter means having two cutting edges disposed at an angle to each other, a pair of guide edges for guiding said sheet material, metal sheet and the like, two guides formed in said machine bed, each guide extending parallel to a respective one of the two cutting edges, two slide means each arranged to move along a respective one of said two guides in a direction parallel to the respective cutting edge, connecting means articulatingly connecting said guide edges respectively to the two slide means to form two respective guide edge and slide assemblies, drive means operable to apply driving force to each guide edge and slide assembly alternately in one direction and the opposite direction along the respective guide, selectively adjustable stop means on the connecting means, said stop means being operative to cause the driving force to effect selectively either translation alone or rotation alone or both translation and rotation of the respective guide edge, the guide edges being equipped with means for controlling the operation of the vertically reciprocable slide and the vertically reciprocable slide carrying elements for controlling the drive means. |
