摘要： A system for forming bends in a portion of a tubular work piece includes a roller assembly having rollers. The work piece is supported such that the portion thereof is aligned with the rollers along an axial direction, and such that the work piece can be advanced in the axial direction. At least some of the rollers are guided along a path around the perimeter of the work piece, such that a pressure exerted by the rollers on the work piece increases from a minimum value to a maximum value along a first half of the path and decreases from the maximum value to approximately the minimum value along a second half of the path. The system includes an adjuster assembly for moving the roller guide structure along a direction that is inclined relative to the axial direction, for varying the maximum value of the applied pressure.

摘要： An apparatus for bending and forming sheet metal into U-shaped channel members is comprised of a support block for supporting a blank of sheet metal in a centered position, a pair of rollers that engage in rolling contact against opposite ends of the sheet metal, and an anvil around which the sheet metal blank is formed into the U-shaped channel member. The sheet metal blank is formed over opposite sides of the anvil by the rollers engaging in rolling contact against the opposite ends of the sheet metal blank. As the rollers roll over the opposite ends of the sheet metal blank, they bend and form the sheet metal ends into channel bends having acute interior angles. When the rollers are removed from the sheet metal ends, the resiliency of the sheet metal causes the channel bends to spring back from their acute angle configurations to right angle configurations. The rolling contact of the rollers over the opposite ends of the sheet metal produces the channel bends in the sheet metal without producing tooling marks in the surface of the sheet metal.
摘要翻译： 用于将金属板弯曲和成形为U形通道构件的装置包括用于将金属片坯料支撑在中心位置的支撑块，一对与金属板的相对端接触的滚子，以及 砧座板周围形成有钣金坯料。 金属板坯通过与金属板坯件的相对端滚动接触的辊形成在砧座的相对侧上。 当辊子滚动在金属板坯件的相对端部时，它们弯曲并且将金属片端部形成具有锐角内部角度的通道弯曲部。 当从金属板端部移除辊子时，金属板的弹性使得通道弯曲部从其锐角构型向右回转配置。 辊子在金属板的相对端上的滚动接触在金属板材中产生通道弯曲而不在金属板的表面中产生模具标记。

摘要： A FORMING DIE HAVING A BASE MMBER AND AN ELONGATED FORMING MEMBER SECURED TO THE BASE MEMBER, THE FORMING MEMBER HAVING AN INNER SURFACE, AN OUTER SURFACE AND A CONNECTING SHEET CONTACTING SURFACE. THE FORMING MEMBER DEFINES AN ELONGATED RECESS DISPOSED GENERALLY AT THE INTERSECTION OF THE INNER SUFACE AND THE SHEET CONTACTING SURFACE. A CYLINDRICAL ROLLER WHICH IS ROTATABLY SUPPORTED IS DISPOSED WITHIN THE RECESS. IN ONE FORM THE DIE IS PARTICULARLY SUITED TO BENDING DECORATED SHEET WITHOUT CREATING SURFACE DAMAGE. IT HAS TWO SPACED PARALLEL FORMING MEMBERS SECURED TO THE BASE MEMBER IN CHANNEL DEFINING POSITION. THE FORMING DIE MAY HAVE THE ROLLERS IN CONTACT WITH THE FORMING MEMBER WITHIN THE GENERALLY CYLINDRICAL RECESS OR MAY HAVE UNITARY OR SEGMENTED SPACER MEANS INTERPOSED BETWEEN THE ROLLERS AND THE FORMING MEMBER. THE SPACER MEANS HAS A CONCAVE SURFACE OF SUBSTANTIALLY THE SAME RADIUS OF CURVATURE AS THE ROLLER, IN CONTACT WITH THE ROLLER.

摘要： A method for producing a joint outer part by means of flow forming is provided. A blank is arranged on a contour mandrel such that it cannot rotate with respect to the contour mandrel. The contour mandrel is driven in such a way that the blank and the contour mandrel rotate about a common axis. The blank is shaped at least partially with the aid of a flow forming roller which acts on the blank in order to form the joint outer part. At least one track is formed with a concave region in the joint outer part.

摘要： A roll bender machine for bending metal sheets which includes a roller driven in rotation and about which the sheet metal is rolled and at least two backing rollers adapted to receive and bear against a sheet while it is being bent around the roller. The backing rollers are mounted to rotate on a support that is adjustable. The bending roller and backing rollers are each associated with at least one set of devices for compensating their deflection. An arm is mounted on the machine for receiving coiled sheet metal and is provided with a housing in which the bending roller is at least partially received.

摘要： A computer controlled roll-forming apparatus is adapted to provide a repeating pattern of different longitudinal shapes to a continuous beam “on the fly” during the roll-forming process. A sweep station of the apparatus includes a primary bending roller tangentially engaging the continuous beam along the line level and an armature for biasing the continuous beam against the primary bending roller for a distance partially around a downstream side of the primary bending roller to form a sweep. Actuators adjustably move the armature partially around the downstream side of the primary bending roller between multiple positions for imparting a series of different longitudinal shapes. Internal and external mandrels control wall stability to allow even sharper sweeps. In one form, the apparatus also includes a coordinated cut-off, so that when separated into bumper beam segments, the ends of the individual beam segments have a greater sweep than their center sections.
