Abstract: The invention relates to a joint bush, for use in a joint between two components or workpieces, comprising a first sleeve-like bush section, which transforms at one sleeve end into a second flange-like bush section which projects over the circumferential surface of the first bush section.

Abstract: The invention relates to a novel design of hydraulic processing pincers for processing workpieces, with a tool which, in a first tool part has an axially displaceable tool plunger which, with a first end or with a tool provided there and an opposite work rest, forms a working region or a working gap and can be moved with the first end towards and away from the work rest, and made up of a hydraulic actuating device for applying a force to the tool plunger via a movable pressure-transmitting element, said force moving said tool plunger in the direction of the work rest. The piston and/or the piston rod are/is designed with a cavity in which the tool plunger is accommodated in its initial position at least over part of its length.

Abstract: Process for attaching a functional element to a plastically deformable flat material or workpiece, the functional element on a contact surface having a rivet collar which is formed by a hollow or tubular section and which stands away over this surface, in the joining area in the flat material by plastic deformation a dome-like section being formed which with its base projects over the plane of the flat material surrounding this section and on the base has a joining opening, and the attachment of the functional element to the flat material in a joining and riveting process taking place by insertion of the rivet collar into the joining opening and by plastic deformation of the rivet collar such that the base is held in a region of the base which surrounds the joining opening between the deformed rivet collar and the contact surface or end side of the functional element, the functional element being anchored on the edge region which surrounds the joining opening without reducing the diameter of the joining openi

Abstract: A supply unit for positionally correct feeding of component parts, for example connecting elements, from an unordered quantity in a holder to a processing unit, comprising a sword-shaped conveyor element with a drive unit for moving at least one section comprising a transport or conveyor surface of the conveyor element in a back and forth stroke movement along an inner surface of the holder, the component element dips into an area of the holder occupied by the component parts, and transports the component parts to a transport route provided above said area for transporting away the required component parts with the conveyor element to the transport route.

Abstract: The invention relates to a method for introducing at least one connecting element into a workpiece using a tool composed of at least one part. In said method, before the connecting element is joined and connected to the workpiece, the tool is precisely aligned in relation to the workpiece by means of at least one locating and centering element that engages with a centering region of the workpiece and by the relative displacement of the tool part and the workpiece. The invention also relates to an associated device.

Abstract: The invention relates to a method for emplacing connecting elements in metal sheets or sheet components made of metal by inserting a bolt-like or sleeve-like joining section of the connecting element into a joining opening provided in a metal sheet, so that the connecting element bears with an extended head section against one surface side of the metal sheet and projects with a partial length of the joining section over the other surface side of the metal sheet, and by subsequent pressing of the connecting element in the metal sheet through plastic material deformation by applying a pressing force.

Abstract: Disclosed is a supply unit for feeding or making available components, e.g., punching nuts or similar joining elements. Said supply unit comprises a bin that forms a storage space and is used for stocking a random number of components, and a unit for removing the components from the storage space and redirecting the components in an oriented manner, among other things.

Abstract: The invention relates to a novel system for inserting or mounting nuts in workpieces by means of welding. Said system comprises a welding station to which the nuts are fed via a conveying section.

Abstract: The invention relates to a system for introducing studs (2) into work pieces by welding using a welding station which is supplied with the studs via a conveyor section (11).

Abstract: A set head for setting clip nuts on workpieces by means of pushing, having at least one channel embodied in the set head, which (channel) ends at one front end of the set head in an output or mounting opening, with which the set head can be positioned for setting the clip nuts on workpieces.

Abstract: A hydraulic processing tong for processing workpieces, with a tool, has a first tool part with an axially movable press ram or plunger, which with a first end or a tool located there and an opposing workpiece assembly forms a work area or work gap and with the first end can move toward and away from the workpiece assembly, and with a hydraulic actuating device for applying a force to the press ram, causing it to move in the direction of the workpiece assembly.

Abstract: The invention relates to a method for manufacturing a hinge between two workpieces or components; first a hinge socket is inserted in an opening of the first component and then a hinge pin is inserted in the hinge socket; the second component can be fastened to the hinge pin end protruding from the hinge socket.

Abstract: The invention relates to a new design for a hydraulic processing tong for processing workpieces, with a tool, which in a first tool part has an axially movable press ram or plunger, which with a first end or a tool located there and an opposing workpiece assembly forms a work area or work gap and with the first end can move toward and away from the workpiece assembly, and with a hydraulic actuating device for applying a force to the press ram, causing it to move in the direction of the workpiece assembly.

Abstract: The invention relates to a novel machining tool and a punching head for use in one such tool. An internal feed channel is formed between the connection for the external feed of components and the readiness position on the joining channel at least over a partial length of a deformable or flexible internal feed, so that the run of this feed within the tool and/or the correction of the feed to the external supply can be optimally matched to the respective tool execution.

Abstract: A device for fastening functional parts in a component produced from a flat material, preferably sheet metal, by insertion and pressing, having several punching heads and opposing tool surfaces assigned to them. The component is located between the punching head and the pertinent opposing tool surface when the functional part is inserted. There are punching heads on a first tool part. The opposing tool surfaces are formed by thrust bearings which are provided on the top of a second plate-shaped tool part. The tool parts can be moved relative to one another for opening and closing the tool or the device and there are centering/guide and locking devices acting directly between the tool parts. When the tool parts are closed, the tool parts are directly centered and locked to one another. Each punching head is provided with an individual drive.
