The disclosure relates to systems and methods for machine-cutting workpieces in plate form or bar form and also to a machine tool, with a laser machining device, and a workpiece support, by which a workpiece to be machined in the laser machining device is received, and with a workpiece moving device, by which the workpiece to be machined is held and moved in relation to the laser machining device, wherein with a machining head a laser beam is directed onto the workpiece to be machined and a clearance or recess is introduced into the workpiece and the clearance is machined with a flow drill and widened to a final size of a borehole.

A method for hot forming, in particular for press hardening, a component is disclosed, wherein in a local region of the component a reduced martensitic hardness is produced by locally reducing a forming pressure which is exerted on a surface of the component.

A multi-diameter tubular body is cold-forged by forming a large-diameter hole portion in a formed body having a preliminary hole through subjection of the preliminary hole to deep hole forming and by punching out the bottom surface of the large-diameter hole portion to thereby form a small-diameter hole portion. Since a punch having a central protrusion on its forward end surface is used, an internal flaw is generated by dead metal in the inner circumferential surface of a depression, formed by the protrusion, in the bottom surface of the large-diameter hole portion. An outside diameter of a protrusion of a deep hole forming punch is rendered smaller than an inside diameter of the small-diameter hole portion to be formed later by punching out the bottom surface of the large-diameter hole portion. As a result, the internal flaw is removed when the small-diameter hole portion is formed.

A cast part includes a metallic functional region. The functional region extends in a first direction from a first side to a second side of the cast part. The cast part has a surrounding region at least partially surrounding the functional region. The functional region is shaped by a friction-based process. Further disclosed is a piece of equipment, such as an electrical machine which includes a further component and a device for securing the further component against twisting. The device has a connection between the functional region of the cast part and the further component.

A method for producing a blind hole in a metallic workpiece having at least one curved surface. One part of the material is pushed starting from approximately the horizontally extending curved tangent and from there approximately perpendicular in the direction of the material of the workpiece by means of reciprocating movement. Said method consists of the following steps: a) providing the workpiece with a matrix-type receiving element for the material which is to be displaced; b) pushing the workpiece material by means of a stamp in the axial direction of the receiving element, said material stamped by the stamp is initially sheared in an adiabatic state and flows partially into the receiving element; c) removing the material projecting from the receiving element.

Embodiments of the present invention relate to a handling device for handling a metal component part between a furnace device and a further processing device. The handling device comprises a temperature-control chamber, in which the metal component part can be inserted, and a conveying device. The temperature-control chamber comprises a temperature-control unit that adjusts a temperature in the temperature-control chamber. The temperature-control chamber can be conveyed between a receiving position, in which the metal component part can be conveyed from the furnace device into the temperature-control chamber, and a dispensing position, in which the metal component part can be conveyed from the temperature control chamber to the further processing device. The conveying device is configured in such a manner that the metal component part can be conveyed in the receiving position by means of the conveying device between the furnace device and the temperature-control chamber and that the metal component part can be conveyed in the dispensing position by means of the conveying device between the temperature-control chamber and the further processing device.

A collating system for rivets is provided that includes a rivet holder for supporting rivets in a predetermined pattern. In one form, the rivet holder includes a body having cavities for supporting the rivets therein. The rivet holder body includes a top plate member and a bottom plate member. The rivet holder has drive heads connected to the top plate member via frangible portions and the bottom plate member has retaining webs disposed below the drive heads. The top and bottom plates are secured together to capture heads of the rivets between the drive heads and retaining webs. The drive heads may be driven downward to drive the rivet heads from the rivet holder and into bores of a guide block with the retaining webs flexing to release the rivet head from the lower bottom plate member. A method of using the rivet collating system is also disclosed.
