Abstract: The invention relates to an exchangeable tool having a tool body with a receiving end for holding the tool in a receiving structure, wherein connecting means are arranged in the tool body for providing a substantially non-rotatable connection with a manipulator for manipulating the tool into and out from the receiving structure, to a combination of such tool with a manipulator for manipulating the tool into and out from a receiving structure, and to a method for manipulating such tool into and out from a receiving structure.

Abstract: The invention relates to a combination of a press brake tool and a press brake clamping system for pressing the press brake tool in a press direction, said press brake clamping system comprising: at least one clamp for clamping said tool in a clamping direction substantially perpendicular to the press direction; a positioner for positioning said tool in the press direction; and at least one tool support surface; said tool comprising: a tool body; a clamping part arranged on said tool body for clamping said tool in said clamping system, wherein the clamping part has an engagement part for engagement of the positioner onto the tool; at least one support surface for abutment to said tool support surface; and a safety tang to prevent the tool of falling out; wherein at least one of the positioner and the engagement part comprises a slanting surface for at least partially transforming the clamping force into a positioning force.

Abstract: The invention relates to a combination of a press brake tool and a press brake clamping system for pressing the press brake tool in a press direction, said press brake clamping system comprising:

Abstract: An American style press brake tool and tool holder having a safety key. The holder has a body with walls defining a downwardly open, tool receiving recess having a top, a downwardly facing force-delivering shoulder adjacent the bottom of said recess, and a shelf within said recess having an upwardly facing surface spaced upwardly from said force-delivering shoulder. The tool comprises a body having a lower work-engaging surface, an upwardly facing force-receiving shoulder engageable with the shoulder of the tool holder, and an upwardly extending tang receivable in said recess, the upper end of the tang being spaced from the top of the recess. A manually operable actuator is spaced below said force-receiving shoulder, and a safety key is coupled to the actuator for movement horizontally into and out of alignment with the shelf between locked and unlocked positions, respectively.

Abstract: The invention relates to a press tool with a receiving structure end for receiving into a receiving structure of a folding press, which end is connected via a central portion to a tool end, comprising at least one safety member which can protrude out of a side surface of the receiving structure end, to an adaptor therefor and to a press equipped therewith.

Abstract: The invention relates to a press such as a folding press and a deep-draw press comprising a press frame with a lower yoke and an upper yoke which are mutually reciprocally movable, wherein the lower yoke and the upper yoke are each provided with co-acting tools and wherein between a yoke and its tool are arranged a curve forming device which comprises a series of curve-forming wedge pairs which lie distributed over the length of the yoke between the yoke and the tool, wherein each curve-forming wedge pair is provided with an apparatus for adjusting the mutual position of the curve-forming wedges of a curve-forming wedge pair.

Abstract: The invention relates to a clamping device for the clamping of at least one piece of tooling, for instance an upper tooling or a press, which device comprises:two clamping jaws moveable towards and away from one another, between which the tooling can be clamped,pressure means, for instance at least one hydraulic cylinder for pressing the clamping jaws towards one another with force at energizing thereof, andat least one locking element present between the clamping jaws for co-action with an edge present on the tooling,such that the tooling in the absence of energizing of the pressure means can be pushed with at least one edge over the locking element, hook over the edge, and thus prevents the tool from falling,and is characterized in thata resilient strip, which is attached between the clamping jaws to one clamping jaw and which as a result of its own resilience lies in untensioned state at a distance from a pressure surface of this clamping jaw, whereby in the absence of energizing of the pressure means, the

Abstract: A press that includes a frame which bears a bending device that includes an upper tool and a lower tool which can be moved in a mutually reciprocal manner. The press also includes a curve-forming element for forming a curve on the bending device. The curve-forming element has curve-forming members slidable over each other in a lengthwise direction and a transverse direction and making contact with each other. The contact surface of the curve-forming members in the lengthwise direction and the transverse direction of the bending device possess the respective determined angles of slope .alpha. and .beta.. The press has an element for adjusting the curve-forming members in the lengthwise direction and the transverse direction, wherein the curve-forming members adjoining each other at the sides preferably form a curve-forming strip which extends substantially over the whole length ofthe bending device. This curve-forming strip is preferably provided with a number of discrete contact surfaces.
