Abstract

La présente demande concerne un rayon et son procédé de préparation, et se rapporte au domaine technique de la fabrication de rayons. Le procédé comprend les étapes consistant à : réaliser un moulage par étirage positif et un poinçonnage sur une plaque pour obtenir une ébauche de rayon arquée, et former un pré-trou au milieu de l'ébauche de rayon; réaliser un formage par extrusion et une finition de diamètre sur l'ébauche de rayon pour obtenir un produit semi-fini de rayon avec une surface de contour, le bord droit du produit semi-fini de rayon ayant une perpendicularité prédéfinie; poinçonner le produit semi-fini de rayon pour former un trou d'air et un trou de fond de trou de vis dans le produit semi-fini de rayon; et finir le produit semi-fini de rayon poinçonné, et extruder le trou de fond de trou de vis à la taille pour former un trou de vis pour obtenir un produit fini de rayon. Dans chaque processus, un moule composite est adopté, et le traitement d'une pluralité de caractéristiques fonctionnelles du produit est achevé à un moment au moyen d'un processus, de telle sorte que le processus de l'ensemble du processus de fabrication est simplifié, l'apport du dispositif et de la main-d'œuvre correspondants est réduit, la main-d'œuvre et les ressources matérielles sont économisées, le coût de production est réduit, et l'erreur d'accumulation dans le processus de traitement de produit est réduite sans aucun doute, de telle sorte que la précision de traitement du produit est améliorée, et l'efficacité et le rendement de production sont améliorés de manière correspondante.
