Abstract

Sont divulgués dans la présente invention un dispositif d'usinage et un processus de formation de striction d'un tube de cigarette électronique. Le dispositif d'usinage comprend une table d'usinage, un cadre supérieur, une plaque de montage, un ensemble de formation de striction, un ensemble bras mécanique, une table de chargement de matériau et une table d'évacuation de matériau, la partie supérieure de la table d'usinage étant reliée au cadre supérieur au moyen d'un support et la plaque de montage étant disposée sur le cadre supérieur ; et un cylindre pneumatique de striction dans l'ensemble de formation de striction étant disposé sur la plaque de montage. Selon la présente invention, l'ensemble bras mécanique est utilisé en association avec une plaque de base de matrice inférieure pour réaliser le chargement et l'évacuation automatiques de matériau pour la striction, ce qui permet d'obtenir un degré élevé d'automatisation et de réduire l'intensité de main-d'œuvre des travailleurs. Au moyen d'un arbre rotatif et d'un bloc de fixation de matrice supérieure qui sont prévus, de multiples processus de striction peuvent être réalisés au cours d'un processus d'installation, ce qui permet d'améliorer l'efficacité de production. La rotation d'un tuyau au cours de la formation de striction est obtenue au moyen du moteur électrique de matrice inférieure fourni, ce qui permet de réduire une force radiale pendant la formation et d'améliorer un taux qualifié après la striction. Le tuyau est soumis à un chanfreinage au moyen d'un processus de meulage et de chanfreinage pour éviter d'endommager une matrice de striction, ce qui permet de prolonger la durée de vie de la matrice de striction.
