A punch and die set and selection apparatus adapted for sheet material forming, to work cooperatively with an automated punch press to select one of a set of punches and dies to operate within said apparatus to be engaged with the punch-press load-applying ram and tool holders, and to compel or allow the non-selected dies to be moved away from the sheet material so as not to impinge on or damage the sheet material being formed.

A fastening device for fastening a processing tool to a machine tool, in particular to a press device, comprises at least one locating body, against which the processing tool can be clamped, a clamping unit for the releasable clamping of the processing tool to the at least one counter clamping body, and a locking connection for the releasable connection of the clamping unit to the at least one counter clamping body.

A machine for machining, such as cutting and/or forming, planar workpieces has an upper tool and a lower tool that are movable toward each other to machine a workpiece arranged therebetween. The upper tool includes at least one cutting tool having at least one cutting edge and a clamping shaft. The lower tool includes a main body having a support surface for the workpiece. The support surface has an opening associated with an inner counter cutting edge. The lower tool has a positioning axis and at least one outer counter cutting edge provided outside of the opening and associated with the support surface. The outer counter cutting edge is aligned with an outer face of the support surface. A distance of the outer counter cutting edge from the position axis and a distance of the inner counter cutting edge from the position axis deviate from each other.

A multiple tool for a punching device, in particular for a turret punch press has a housing and a tool head interacting with the punching device. A thread cutter magazine including a plurality of thread cutters is connected to the tool head. A selection device is provided to select an active thread cutter which interacts with a workpiece for thread cutting. A thread cutter drive device is provided to drive the active thread cutter. As a result, a multiple tool is obtained which expands the range of applications of a punching device.

A processing system for a workpiece, with a thread formation device (44) for forming a thread in a workpiece, comprising a housing and one or more tool take-ups for a thread forming tool, rotatably and displaceably mounted in or on the housing, a linear drive and a rotational drive for the tool take-up(s) and a take-up device with one or more take-ups (19) for integrating the thread formation device (44), is characterized in that the thread formation device (44) can be integrated into the take-up device by means of a disconnectable plug connection.

This roll cutter device is provided with roll units in which a thin plate material is passed between a pair of rolls. Three sets of the roll units are provided in an axial direction of the rolls in such a way that central axes of the rolls lie on one straight line in the axial direction. The configuration is such that a plurality of the roll units including an upper roll and a receiving roll exist in the axial direction.
