摘要:
A roof frame arrangement of a motor vehicle has a front, a rear and two lateral roof frames, and a supporting device for a motor vehicle tailgate. The supporting device includes a tailgate hinge and at least one gas-filled compression spring. At least the lateral roof frame contains an inner shell and an outer shell connected to the latter. A hollow space is formed between the inner shell and outer shell. In order to provide a roof frame arrangement having increased stiffness, which can be produced in a simple and space-saving manner and with as few manufacturing tolerances as possible and in which a relatively great outlay on leakproofness is not required, it is proposed to form a rear end region of the lateral roof frame as a single-piece, circumferentially closed hollow profile which encloses the hollow space there and forms a receiving housing in which at least one of the hinge and the gas-filled compression spring is fitted.

A rear roof frame of a motor vehicle has a tailgate which is fastened to the roof frame and includes an upper shell and a lower shell which is fitted to the latter. For the design of a rear roof frame, which, in spite of the shell-type construction, provides, in a simple manner and lightweight construction, sufficient torsional and flexural stiffness in order to withstand high mechanical stresses, it is proposed to arrange within the shell structure a hollow profile which leads in each case from the transition region to the lateral roof frame and parallel to the longitudinal extent of the structure, and emerges, at least at the end facing away from the lateral roof frame, in a knee which kinks in the front-end direction of the vehicle. The end of the rear roof frame forms a tubular hollow profile of the lateral roof frame, which is connected to the hollow profile of the rear roof frame.

In a method and apparatus for producing a composite component comprising a hollow profile and at least one injection-molded element, a hollow profile (3) is formed by means of internal high pressure fluid forming and is encapsulated with an injection molding material to form the injection-molded element. The hollow profile is expanded by means of internal high pressure in a closed combination tool comprising an internal high pressure forming tool element and an injection molding tool element, before it is encapsulated. The hollow profile is pressed on the tool engraving only locally in the region of the location to be encapsulated, keeping the outlet of the injection molding channel opening into the tool engraving clear.

The invention relates to a method for applying soft solder to a mounting surface of a component, wherein a connecting means comprising a carrier layer and a soft solder layer formed by physical vapor deposition on the carrier layer is brought into mechanical contact between the soft solder layer and the mounting surface, such that a first bond strength between the soft solder layer and the mounting surface is greater than a second bond strength between the soft solder layer and the carrier layer. The connecting means is subsequently removed from the component so that the carrier layer releases from the soft solder layer in the area of the mounting surface and thus soft solder remains only at the mounting surface.

A method is disclosed for joining an electrical contact of minor thermal function to a high-power diode laser bar, comprises the step of joining the contact and the HDB by a joining material containing an adhesive. A high-power diode laser bar-contact arrangement comprises a high-power diode laser bar, an electrical contact of minor thermal function and a joint zone between the HDB and the contact. The joint zone contains a joining material with an adhesive. The disclosure also describes a high-power diode laser comprising an HDB, two electrical contacts of minor thermal function and two joint zones between the contacts and the HDB. The joint zones contain joining materials with adhesives. A high-power diode laser stack is also described.

A method and an apparatus are provided for internal high-pressure forming of a workpiece in a closed internal high-pressure forming die. The workpiece is expanded owing to the internal high fluid pressure exerted by a pressure generator and coming to rest on the cavity of the forming die. The workpiece and the forming die form friction partners in the areas of contact. In order to improve process reliability during the internal high-pressure forming of workpieces and to expand the scope of the method, vibration is imparted directly to at least one of the friction partners by a vibration generator during forming.

A device for manufacturing a hollow body from two plates. The device includes an internal high pressure forming tool having an interior surface defining a mold chamber corresponding to a shape of the hollow body. The forming tool being arranged to receive two plates resting against each other. An expansion lance is insertable between the plates via an axial drive, and the expansion lance and the axial drive forming a pushing plunger. The expansion lance has a pinching section along a circumferential contour, and the plates to be pinched are arranged between the pinching section and the forming tool. The expansion lance includes a feed bore communicable with a high pressure fluid source. The expansion lance defines an axial stop to abut axial edges of the plates. The axial stop has a radial periphery which is smaller than that of the mold chamber.

A method for performing a filleting cut for filleting fish which are conveyed tail-first is carried out along a row of wedge-shaped ray bones projecting away from a main bone stem with a wedge width increasing from ray bone to ray bone by means of a pair of circular knives having sharp cutting edges. Starting from the tail end, meat of each fish is cut by means of the circular knife pair having a V-shaped arrangement as a result of the fact that a cutting gap having the smallest cutting edge spacing is set to a basic size which is at least substantially equal to or smaller than a wedge width of the outermost ray bone at the tail end of the conveyed fish. In the fixed position of the V-shaped arrangement, the ray bones are guided through the cutting gap, wherein the circular knife cutting edges, which in their cutting edge region are flexibly deformable out of the associated circular knife surface counter to an elastic restoring force, are displaced counter to the elastic restoring force by means of the broadening ray bones with increasing widening of the cutting gap. A tailored suitable apparatus comprises a circular knife pair having cutting edges which, in the fixed V-shaped arrangement, are designed such as to be able to be deformed with a degree of deformation defined by the difference between ray bone wedge widths. Circular knives configured for the apparatus may each have a cutting edge region which is deformable in a wave-like manner along the cutting edge as a result of a bending pressure transverse to the circular knife surface.
