Cutter device for hollow components produced by internal high pressure forming has holder ring to support component during cutting

摘要

The cutter device uses a rotating cutting blade and medium pressure inside the hollow component. The blade has an associated support body formed by a holder ring (26,27), which moves along the length of the hollow component. To cut a domed cap off a dome-shaped branch of a component, the ring is placed into a transverse aperture of the tool to surround a support plunger charging the cap. Instead of the ring, a stationary elastomer body may be used. A cutter ring (24) is located next to support ring/elastomer body.
