The invention comprises a method of forming a sheet metal cup without using a mandrel. A cup shaped blank (10) is first produced having a relief (11) on a rim (12) or outer circumference. The blank (10) is clamped in the spinning machine. The relief (11) controls and facilitates the bending process, creating a uniform curve at a predetermined bending point. During the rolling process, a forming roller (20) is engaged with rim (12), and is moved progressively parallel with an axis of rotation (A-A). As the forming roller (20) moves, the rim (12) is progressively bent from an orientation normal to an axis of rotation to a position parallel to the axis of rotation. The fully formed rim (12) can then be punched to accommodate a bearing or shaft. This allows a small radius pulley to be formed without use of a mandrel.

L'invention concerne un procédé de formage de cuvette à partir d'une feuille métallique sans mandrin. Le procédé comporte les étapes consistant à produire d'abord un flan en forme de cuvette qui comporte un relief sur un rebord ou bord extérieur ; à serrer le flan dans une machine à repousser, le relief permettant de régler et facilitant le processus de cintrage ; à produire une courbure uniforme à un point de courbure prédéterminé ; à mettre en contact, pendant le processus de laminage, un galet de formage avec le rebord, et à le déplacer de manière progressive parallèlement à l'axe de rotation ; à cintrer progressivement le rebord, à mesure que le galet de formage se déplace, d'une orientation perpendiculaire à un axe de rotation à une position parallèle à l'axe de rotation. Le rebord complètement formé peut ensuite être embouti pour contenir un roulement ou un arbre. Ce procédé permet de former une poulie de faible rayon sans utiliser de mandrin.
