FIELD: plastic working of metals, possibly manufacture of parts with variable wall thickness from sheet blanks.
SUBSTANCE: forming apparatus includes die and sectional punch and in addition it includes support arranged over die. Between die and said support gasket is placed with possibility of changing it. Central punch has axial recess for placing buffer gasket having plug or draw plate overlapping it in order to provide desired resistance of buffer gasket to metal flowing process.
EFFECT: possibility for forming large size parts at high accuracy.
