Abstract:Aming at the processing problem of the thick wall head cover shell which has small plane back cover,
quadratic curve shape,large diameter,we put forward a new method of conventional-sheear composite spinning using
single die,which is different from the traditional conventional spinning and shear spinning,integrating several technology
contents including thick plate short shear incremental forming path design,and conventional spinning preforming
and short shear forming path design,the controlof double-roller mirror spinning,hot spinning temperature curve calibration.
Through trial,we explore the basic rules of the multiprocess conventional spinning performing and conventional-
sheear composite spinning using single die, summarize the spinning trajectory design method. Single-die forming of
quadratic curve shape thick wall head cover is realized. Accuracy error such as diameter, wall thickness,profile are
less than 0. 2 mm.
