    摘要： Press systems for manufacturing hot formed structural components are provided. The systems comprise a fixed lower body, a mobile upper body and a mechanism configured to provide upwards and downwards press progression of the mobile upper body with respect to the fixed lower body. The system further comprises a cooling tool configured to cool down a previously heated blank which comprises: upper and lower mating dies, the lower die connected to the lower body with one or more lower biasing elements and/or the upper die connected to the upper body with one or more upper biasing elements. The system further comprises a press tool configured to draw the blank, wherein the press tool is arranged downstream from the cooling tool. Moreover, methods for hot forming structural components are also provided.

    摘要： A vehicle crash box (100a, 100b) for attaching a bumper beam (200) to a vehicle (230). The vehicle crash box (100a) comprises a tubular member (102) having a longitudinal extension (104) extending in a longitudinal direction (106); and an interface (108) for the attachment of the tubular member (102) to the bumper beam (200). The tubular member (102) comprises a plurality of longitudinal walls (110a-d) having a longitudinal extension (112a-d) extending in the longitudinal direction (106). The plurality of longitudinal walls (110a-d) comprises two lateral walls (110a-b) opposite one another. The lateral wall (110a; 110b) comprises two or more lateral sides (114a-c; 116a-c) spaced apart from one another in the longitudinal direction (106). The lateral side (114a-c; 116a-c) has a longitudinal extension (118a-c; 120a-c) and a transverse extension (122a-c; 124a-c). The two or more lateral sides (114a-c; 116a-c) of the lateral wall are aligned in the longitudinal direction (106). The transverse extensions (122a-c; 124a-c) of the two or more lateral sides (114a-c; 116a-c) of the lateral wall (110a; 110b) decrease in a direction (128) away from the interface (108).

    摘要： The present application relates to a bumper beam arrangement (10) for a vehicle, comprising an elongated beam (12) having a central flange (14) and webs (16) on each side of the central flange, wherein the webs at a central section (22) of the beam have a first extension (e1), the webs at outer sections (24) of the beam have a second extension (e2), wherein the second extension (e2) is less than the first extension (e1), the extension of the webs gradually decreasing between the central section and the outer sections. It further comprises an elongated cover plate (30) attached to said beam, having a central flange (30, 36) and webs (38) on each side of the central flange, wherein the webs of the cover plate have extension profiles that correspond to the webs of the beam, such that the beam arrangement obtains a generally uniform thickness along its length.

    摘要： The invention relates to crash bracket (10) for attaching a bumper beam (2) to a side beam (20) The bracket comprises a first attachment flange (11) and a second attachment flange (12) for attachment to upper and lower sides (21,22) of the side beam (20), respectively, a support portion (13) configured to align with and attach to a web (3) of the bumper beam (2), the support portion (13) having a proximal side (13A) configured to be arranged facing a centre portion (2A) of the bumper beam (2) and a distal side (13B) configured to be arranged facing an end portion (2B) of the bumper beam (2), opposite to the proximal side (13A), and first and second leg portions (14,15) that connect the support portion (13) to the respective first and second flanges (11,12), wherein the first and second leg portions (14,15) at least partly extend orthogonally with respect to the first and second flanges (11,12) and the support portion (13). A notch (17,17') is provided at the proximal portion (14A,15A) of the leg portions (14,15) to provide deformation guides for the leg portions (14,15).
