摘要： The present invention provides a method and apparatus for manufacturing a closed structure part without flange having a curvature and welded edges along a longitudinal direction of the part and further having a varying cross-sectional shape, from two metal plates. In conventional techniques, it was impossible to simultaneously provide a varying cross-sectional shape and a curvature. In the present invention, it is possible to simultaneously provide a varying cross-sectional shape and a curvature. Each of two metal plates 1a, 1b, which is provided with a curvature along the longitudinal direction of the plate corresponding to the curvature of the part 10 along the longitudinal direction and further provided with both ends in a width direction of the plate corresponding to the welded edges 11 of the part, are press-formed such that a folding line 2 is formed at positions corresponding to a non-welded bent edge 12 in a cross section of the part, and are then stacked on each other vertically such that their bulging sides face outward. Their left ends and right ends in the width direction are mutually welded along the longitudinal direction so as to form welded edges 11. While being guided and conveyed by a pair of left and right rotary rolls 40a and 40b or, in addition thereto, a rotary roll 40c thereunder, the distance between the rotary rolls is changed or, in addition thereto, the rotary roll is moved up and down and the obtained closed structure is made to have a three-dimensional shape by using the folding lines and the welded edges as origins and is thereby formed into a part having the target shape.

摘要： A high-strength beam includes first and second sections bent in opposite directions as part of a roll-forming process. A frame includes side frame members incorporating the double-bent beam and at least one energy management tube attached to the beam. In one form, the beam is tubular and has a cross-sectional dimension of greater than 25 mm and a material strength of at least about 60 KSI tensile strength. A roll form apparatus includes a roll former device and a sweep station in-line with the roll former device for sweeping the continuous beam in first and second opposing directions. Also, a method of roll-forming comprises steps of: roll-forming a sheet of material into a continuous beam and sweeping first and second sections of the beam in opposite directions.

摘要： A semifinished flat tube 30 is for use in producing a flat tube 1 comprising an upper and a lower wall 2, 3 opposed to each other, and left and right opposite side walls 4, 5 interconnecting the upper and lower walls 2, 3 at opposite side edges thereof. The semifinished flat tube is produced from a metal plate 15 having two flat first portions 17, 18 for making the upper and lower walls 2, 3, a second portion 16 interconnecting the two first portions 17, 18 integrally for forming the right side wall 5, and two third portions 9, 10 projecting upward from the respective first portions 17, 18 integrally with the first portion each at a side edge thereof opposite to the second portion 16 for making the left side wall 4, by bending the metal plate 15 to the shape of a hairpin at the second portion 16 to cause the third portions 9, 10 to butt against each other. The two third portions 9, 10 are joined to each other by laser welding intermittently from outside at a plurality of portions spaced apart longitudinally thereof.

摘要： A reinforcement beam for a vehicle bumper system comprises a single sheet deformed to define first and second tubes sharing a common single center wall. A channel rib is formed on each tubes and a crevice rib over the center leg forms a third rib. Edges of the sheet are deformed to a radius so that their surface consistently engages an associated radiused corner formed on ends of the center leg, which facilitates consistent abutting line engagement of material surfaces, and thus facilitates consistent welding. In a preferred beam, front wall sections of each tube are coplanar and form a face of the beam, with each channel rib and crevice rib providing added stiffness to the beam, and yet nothing extends forward of the coplanar front wall sections. Related apparatus and methods are also disclosed.

摘要： A bumper beam is roll formed so that it gets a closed cross section with, along the length, constant cross section having at least two closed chambers (15, 16) separated by an essentially horizontal partition wall (14). Each chamber has a side (19), which is turned away from the vehicle, with at least one longitudinal concave portion (20, 21; 22, 23) extending along the entire length and one side (24), which is facing the vehicle, with at least one longitudinal convex portion (25, 26; 27, 28) extending along the entire length. After the roll forming, some portions (32) of the cross section are pressed together vertically or horizontally in order to adapt the deformation properties.

摘要： A method includes, in combination, a roll former with rolls configured to form a structural beam from sheet material, and a sweep unit for longitudinally sweeping a beam in any of vertical, horizontal, or combination directions. The sweep unit has a first pair of forming rolls positioned to engage first opposing sides of the structural beam and has a second pair of forming rolls positioned to engage second opposing sides of the structural beam. The sweep unit movably supports the first and second pairs of forming rolls so that any selected one of the forming rolls continuously engages an associated side of the structural beam while an associated one of the forming rolls opposing the selected one forming roll moves downstream and around the selected one forming roll. This provides a very stable beam-bending condition promoting dimensional stability during the sweeping process, and hence dimensional accuracy and repeatability.
