(5), carrying out fiber twines;
(6), after fiber twines and to finish, mould is rotated further, and the annular construction member on the core is rotated curing.
A kind of high accuracy control device of fiber wound annular construction member inside circle, it is characterized in that: described device comprises that both sides have the metal core of cantilever, two are enclosed within on the metal core with gap fiting mode and can axially movable unsteady locating ring, wherein metal mandrel surface inclination angle is identical with the inner surface of desiring the moulding annular construction member, and its inclination angle section axial dimension is greater than the width of annular construction member.Unsteady locating ring can be dimensioned to different-diameter guaranteeing being unlikely to excessive with the gap of metal core according to annular construction member, and is connected with fixed disk on being fixed on the metal core by adjusting screw rod, and passes through adjustment screw rod adjusting position.
Advantage of the present invention: determine actual constriction coefficient by pre-winding reference composite material ring, the installation site of accurately regulating two unsteady locating rings thus is to obtain suitable fibre winding zone, realized the high accuracy control of hot setting fiber wound annular construction member inside circle size, stopped annular construction member is carried out that dimensioned causes fibre damage and the reduction of the structural strength that causes, and scheme by rotation curing, guaranteed control to annular construction member inside circle circularity, carrying out Φ 650mm composite annular member when Wrapping formed, interior round dimensional accuracy can be controlled at 0.05mm; Adopt the scheme of the locating ring that floats, can regulate the annular construction member inside circle size, reduced dimension precision requirement to a certain extent Mould Machining by the different installation sites of adjusting locating ring; Owing to the existence at metal mandrel surface inclination angle and the unsteady locating ring that uses different size, can realize the continuous within the specific limits linear change of size of fibre winding zone, make more convenient feasible to the adjustment of annular construction member inside circle size.
