FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in hammer shops for production of hollow parts. The tool comprises the female die, male die and slide thrust secured at the slide to constrain the slide displacement. The mould table supports the shaped extractor. Pressure cage with stepped outer surface and cylindrical through bore is arranged in the female die opening for precise centring of the male die. Distance from the thrust surface closest to the female die axis is larger than the cage appropriate radial size that confines the area facing said thrust surface.
EFFECT: higher efficiency of moulding.
