WIREDRAWING MECHANISM OF AMPOULE PRODUCTION LINE

The utility model discloses a wiredrawing mechanism of an ampoule production line. On the basis of the existing wiredrawing mechanism, the existing four grooved shafts are changed to tetragonal shafts, hexagonal shafts or octagonal shafts; a sliding sleeve is changed to an inner tetragonal sleeve, an inner hexagonal sleeve or an inner octagonal sleeve; the inner sleeves of needle bearings on brackets on both ends are also changed to tetragonal sleeves, inner hexagonal sleeves or inner octagonal sleeves; a convex key is removed, while the rest part dimensions and mounting structures are unchanged. A slide frame with uniform stress and sliding lying flat can raise service life and assembly manufacturability.
