摘要:
A stabilizer (1) used in a vehicle is provided by a tubular element (2) with a middle section (3) and two end sections (4a and 4b), where the end sections (4a and 4b) is bent at an angle relative the middle section (3) so that the stabilizer (1) attains a U-shape. Section surfaces perpendicular to the longitudinal/center axes (A3 and/or A4) of the tubular element at the middle section (3) and/or the end sections (4a and 4b) are of a shape where one of two vectors (V1 and V2) in the plane of a section surface is longer than the other, both vectors originating from the center of gravity of the section surface (P), extending to the periphery of the tubular element and being at an angle relative to each other. A method of manufacturing a stabilizer is also disclosed.
摘要:
A beam is provided for absorbing impact forces imparted to doors and sides of a vehicle body as a result of collisions from the side as well as from the front and rear of the vehicle. The beam (17, 18, 78, 88) is intended to protect people or goods inside the vehicle against personal injury or damage in the case of such an impact. The beam (17, 18, 78, 88) comprises at least one thin walled, closed profile roll formed member (52, 62, 72, 82) defining a cavity (63, 83). At least one wall of the member defines at least one longitudinally extending groove (53, 65, 73, 81). The beam (17, 18, 78, 88) may also be used as a standard building block for structural components.

In a method and apparatus (1,31) for forming a three-dimensional object and in particular to a method and apparatus (1,31) for forming a three-dimensional beam, it is desirable to form three-dimensional beams (5) having complex forms by using an efficient forming process for the beams which may be incorporated into existing high volume production techniques. The apparatus (1,31) for forming three-dimensional beams (5) comprises a support device and an actuation device. Support members (2, 32, 41, 51, 61) spaced about the longitudinal axis of the support device locally define an opening (4, 35, 43, 53, 63) for supporting a section of the beam (5). The position of adjacent openings (4, 35, 43, 53, 63) relative to one another defines the overall form of the beam (5) and the actuation device defines the position of each opening (4, 35, 43, 53, 63).

A beam (2, 22) is provided for use as an A-pillar (21) and roof rail (1) of a vehicle. The beam is a closed profile elongated element defining a longitudinally extending recess (3, 23) for housing a weather strip (4, 24). The recess (3, 23) includes a base (14, 34), an inner wall (15, 35) and an outer wall (16, 36) and the weather strip (4, 24) is attached to the recess (3, 23). The weather strip (4, 24) is attached to the base (14, 34) of the recess by a double-sided adhesive tape (17, 37) pre-applied to the weather strip (4, 24) which adheres to the base of the recess on contact or by application of pressure.
摘要:
The invention concerns a method for manufacturing quenched metal hollow casings of steel by blow-moulding whereby a preheated hollow casing billet, preferably above austenitising temperature, is introduced into a blow-moulding tool (1) and moulded by being expanded against the inner walls of the tool by the introduction of a preheated, pressurized medium into the interior cavity of the hollow casing, whereby the moulded hollow casing (6) is rapidly cooled in a process adapted to obtain quenching of the steel material by the dominating heated medium in the hollow casing being replaced by a pressurized cooling medium and that a cooling medium is led through the moulding tool to achieve its cooling.

In an apparatus for quenching thin walled metal hollow casings (6) manufactured by blow molding, the apparatus has a molding tool (1) defining a slot or aperture (21) and a delivery system for applying a coolant to the slot or aperture (21) of the molding tool (1). In a method of applying a coolant to the external surface of a blow molded casing (6), the coolant is applied onto an external surface of the casing (6) after the casing (6) has been formed against a tool (1) which includes at least one slot or aperture (21).

In an apparatus and method for manufacturing an automotive beam for use as a beam in structural components of automobiles, the beam is provided with significant improvements in terms of torsional rigidity and yield strength. The beam improves the overall safety of passengers and maintains the simplicity of the manufacturing process. The apparatus (1) for manufacturing roll formed profile beams comprises a plurality of material dispensers (2,6), a first set of rollers (5), a second set of rollers (11), a first welding station (10) mounted between the two sets of rollers (5, 11) and a second welding station (12) at the outlet of the second set of rollers (11). The method of manufacturing roll formed profile beams comprises the steps of roll forming a first profile element followed by roll forming a second profile element enclosing the first profile element and forming a closed profile beam having an internal support structure.
