Title

(EN) AN ADAMS CLASP BENDING DEVICE WITH A VERTICAL FIXED SEAT

(FR) DISPOSITIF DE CINTRAGE DE CROCHET D'ADAMS COMPORTANT UN SIÈGE FIXE VERTICAL

Abstract

(EN) This invention relates to an adams clasp bending device and method with a vertical fixed seat. Its structural components include: a rotational delivery structure, an up-and-down sliding structure, a rotational power structure, a support frame structure, a calibration structure, a fixed bending structure, a bending rod, and a cutting blade. The fixed seat of the fixed bending structure is vertically installed, which, in conjunction with the bending head, can bend the double arrow bracket on a Hawley retainer.

(FR) La présente invention se rapporte à un dispositif et un procédé de cintrage de crochet d'Adams comportant un siège fixe vertical. Les composants structurels comprennent : une structure de distribution rotative, une structure coulissant vers le haut et vers le bas, une structure à puissance de rotation, une structure de cadre de support, une structure d'étalonnage, une structure de cintrage fixe, une tige de cintrage et une lame de coupe. Le siège fixe de la structure de cintrage fixe est installé verticalement, pour, conjointement avec la tête de cintrage, permettre de cintrer le support en double flèche sur un élément de retenue de Hawley.
