Abstract: A deflection compensating device is provided for a press brake. The deflection compensating device includes a base member secured to the bed of the press brake. The base member supports two wedges thereon which extend the length of the device. A top member rests on the wedges, and the top member supports the die. The longitudinal ends of the top member, the base member, and the wedges are secured together. The wedges each have upper and lower angled sliding engagement surfaces engaging the top and base members. A screw device is provided to draw the middle of the wedges apart. This causes bowing of the wedges which cammingly bows the top member and the die to compensate for deflection during press operation. A symmetry support structure is provided to ensure that the wedges move equal distances from the center line when drawn apart. Guide pins extend through the top and base members to prevent transverse or twisting movement of the top and base members relative to each other.

Abstract: A compensating bolster and die holder combination for use with the bed of a press brake to provide vertical adjustment and compensating camber to the die holder supported thereby. The die holder is vertically moveable in an open channel of an underlying elongated bolster fitted to the bed of the press; with plural wedge members, moveable transversely of the die holder, serving to adjustably position and support the latter. Each wedge member has joined thereto an indicator pin extending through one side of the bolster which operates to visually indicate the adjusted position of its wedge member; while the several indicator pins cooperate to show the relative adjusted positions of the several wedge members and the consequential adjusted elevation of the die and die holder.

Abstract: A deflection compensating assembly for deflection sensitive fabricating machine tools such as a press brake. In a press brake, for example, the deflection compensating assembly is mounted between the bed and the lower die or between the ram and the upper die. When mounted on the bed, the deflection compensating assembly, under load, will cause the lower die to become substantially parallel to the upper die. The deflection compensating assembly, under load, will cause the upper die to become substantially parallel to the lower die, when affixed to the ram. The deflection compensating assembly, is preferably a self-contained unit attachable to and detachable from the bed or ram and comprises a variable rate spring, the deflection of which, when under uniformly distributed full length load, is such that, when added to the combined bed and ram deflections, it yields a total deflection which is constant along the length of the bed and ram and will compensate for the bed and ram deflections.

Abstract: Hydraulic press including a frame with platens, at least one of which is carried or formed by a pressure plate structure adapted for transferring pressing force to an object between the platens, which press is adapted such that the pressure plate structure is substantially carried solely by horizontally adjustable supports mounted between the defining outer edges of such plate structure, such supports being positionally adjustable such that the surface of the corresponding platen assumes a predetermined shape during the pressing operation. The press suitably includes a mechanical mechanism for effecting the horizontal displacement in order to gain the desired positional adjustment of the supports.

Abstract: A deflection compensating cylinder and auxiliary cross-member assembly, for use with a press brake of the type having a bed, a ram, and a pair of main cylinders actuating the ram. The assembly causes the die-supporting edges of the bed and ram to remain substantially parallel under load. A pair of auxiliary cross-members are located to each side of the bed, extending the majority of the length thereof. The cross-members are affixed to the bed by a pair of pins, each located near an end of the cross-members and extending therethrough and through the bed. The cross-members have corresponding, coextensive, longitudinal slots formed therein and located centrally thereof. The bed contains a similar slot, slightly offset in a vertical direction with respect to the cross-member slots. A deflection compensating cylinder is mounted in the cross-member and bed slots with the cylinder contacting one of the bed and cross-members and its piston contacting the other of the bed and cross-members. The compensating cylinder has a working area four times that of one of the main cylinders. The compensating cylinder is connected to the same hydraulic source as the main cylinders and is subject to the same pressure so that when the bed and ram are under load against a workpiece, the compensating cylinder will remove the downward deflection from the bed and impart thereto an upward deflection substantially similar to that of the ram. The deflection compensating assembly could be mounted on the ram, instead of the bed, to accomplish the same results.

Abstract: The invention relates to a machine for processing metal in sheet or plate form, and especially for bending metal sheets, which includes a machine frame, a table base and a ram vertically displaceable in relation to the table base. An upper tool is mounted on the ram and a lower tool cooperating therewith is disposed on the table base over the U section filled with oil with the sheet therebetween, these two tools bending the metal sheet. One of the tools is supported by a compliant support member for the tool. The compliant support member supporting the tool comprises a plurality of individual elements which are disposed tightly besides each other in the oil in the U section and are independently displaceable in a vertical direction so that, in operation, only those elements are displaced towards the supporting means on which the work sheet rests.
