A device (44) for forming a thread in a workpiece has a housing and a plurality of tool receptacles (2) rotatably and displaceably mounted in or on the housing for a respective thread-forming tool, wherein a linear drive and a rotary drive for the tool receptacles (2) are integrated into the housing.

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.

The invention concerns a stamping tool with a tool upper body, a tool lower body arranged separately from the tool upper body, at least one stamping unit and a guide axis arranged centrally which extends partly through the tool upper body and the tool lower body, wherein the tool upper body is movable relative to the tool upper body and the guide axis guides the movement of the tool upper body.

The invention concerns a stamping tool with a tool upper body, an intermediate plate, at least one stamping unit, in particular several stamping units, a tool lower body to guide the stamping unit and at least two guide pillars to guide the tool upper body relative to the intermediate plate, which are solidly connected to the intermediate plate, wherein the guide pillar is arranged eccentrically and the stamping unit has a stamping punch and a stamping die separate from the stamping punch, the stamping die being operatively connected with the tool upper body.

Tools for machining planar workpieces are provided that include an upper tool, an upper main body, and at least one tool body on the upper main body having a cutting edge. The tools further include a lower tool having a lower main body with a rest surface for the workpiece and a positioning axis oriented perpendicular to the rest surface, at least one counter tool body on the lower main body that has a counter cutting edge that is a closed contour. The cutting edge of the at least one tool body has a cutting contour that corresponds to the closed contour of the at least one counter tool body, and at least one group of at least two counter tool bodies on the lower tool can be associated with the closed contour of the least one tool body.

A punching apparatus includes a beating element that is arranged for interacting with at least one punching tool and is movable inside a container along and around a work axis, a first rotating actuator coupled to the beating element to move it linearly along the work axis between internal and external operating positions and drive the punching tool, and a second rotating actuator connected to the beating element and arranged for rotating it around the work axis, in particular for angularly orienting the punching tool. The second rotating actuator comprises a second electric motor having a stator fixed to the container and a rotor that is internal to the stator and connected to the beating element to rotate it. The rotor extends along the work axis to face, and be engaged with, the stator between the operating positions.

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 drilling tool for a punch device, in particular for a turret punch device, comprises a housing, a tool shank arranged in the housing with a drilling means accommodated therein and a tool head arranged on the tool shaft to interact with the punch device. The tool head of the drilling tool has a ram engagement portion configured to transmit a rotational movement about a tool longitudinal axis from an external drive to the tool head.

A multi-tool is a constituent part of a punch device, in particular of a turret punch press. An upper tool part has a plurality of upper tools which are activatable from a head side via a machine pusher of the punch device for workpiece-machining purposes. A lower tool part has a plurality of lower tools. A workpiece is arrangeable between the upper tool part and the lower tool part. In each case one of the lower tools interacts with an associated upper tool. The number of the upper tools is greater than the number of the lower tools. This results in a multi-tool for extending the possible uses of a punch device.
