Abstract

Procédé de fabrication de fourches avec griffes porteuses. Selon l'invention, on part d'un matériau laminé plat, on chauffe d'abord son extremité et on la refoule axialement dans une matrice pour obtenir la griffe supérieure avec sa rainure 5, puis on chauffe localement à l'emplacement prévu pour la griffe inférieure 2, et on forme celle-ci, avec sa rainure 6, par refoulement axial, enfin on forme le coude 3 et le bras inférieur 8 de la fourche, avec un chanfrein 4 et une extrémité arrondie 9. Application aux fourches de chariots élévateurs.
