Abstract: Apparatus, systems, methods, and articles of manufacture are disclosed herein that flexibly form variable component geometries in a roll-forming process. An example roll-forming apparatus includes a forming unit to move along a stationary component to form a cross-section in the component, a first roll operatively coupled to the forming unit to engage the component, and a second roll operatively coupled to the forming unit to set a forming angle for movement along the component, the component formed between the first roll and the second roll.

Abstract: A plate-shaped workpiece forming method of post-machining a pocket (3) on a curved inner surface of a plate-shaped workpiece (2) in a state where the plate-shaped workpiece (2) curved by a curving machine (10) is spread flat. The method includes a curving step (A) of setting a net curve radius (R0) obtained by adding a curve radius contraction amount (R1) due to spring-in to a finished curve radius (R) of a plate-shaped workpiece (2), taking into account an amount of contraction of the curve radius of the plate-shaped workpiece (2) between before and after machining of a pocket (3) due to spring-in, and curving the plate-shaped workpiece (2) so as to achieve the net curve radius (R0); and a pocket machining step of post-machining the pocket (3) by flatly spreading the curved plate-shaped workpiece (2).

Abstract: When roll-forming a blank into a profile having varying width and upright sides, the vertical position of at least any one of the forming roll pairs (21, 22; 23, 24) is varied 5 on either side during the roll-forming operation while the lateral and rotational positions thereof are simultaneously varied. The profile can thus be given a flat bottom during the roll-forming operation itself.

Abstract: A method for manufacturing a side rail in a vehicle frame assembly includes the initial step of roll forming flat stock to form a side rail having a C-shaped cross section defined by an upper flange corresponding to the top open side of the C-shape, a lower flange corresponding to the bottom or opposite open side of the C-shape, and a web corresponding to the back of the C shape and connecting the upper flange and the lower flange. The terminal edges of the upper flange and the lower flange define an edge plane that extends generally parallel to a vertical plane defined by the web. A portion of the lower flange is then stamped in a direction parallel to the vertical plane to form a kick-up in portion in the lower flange. The edge plane defined by the edges of the upper and lower flanges in the kick-up portion does not extend at the predetermined relationship relative to the plane defined by the web. Then, a portion of the lower flange in the kick-up portion is removed, such as by trimming with a cutting torch, such that the edge plane defined by the edges of the upper and lower flanges in the kick-up portion again extends at the predetermined relationship relative to the plane defined by the web.
