Real-time winding forming device for soft grain core mold explosive-carrying composite shell

Abstract

The invention discloses a real-time winding forming device for a soft grain core mold explosive-carrying composite shell. The real-time winding forming device comprises a composite shell winding forming three-dimensional detection unit and a feedback forming control unit, the composite shell winding forming three-dimensional detection unit is used for obtaining an actual composite shell outer profile size, and comparing the actual composite shell outer profile size with the current fiber layer theoretical model size to obtain the deformation amount and the deformation position of the composite shell; the feedback forming control unit is used for comparing the deformation with a preset threshold value, partitioning the composite shell along the Z-axis direction, adding a fixed number of yarn width sizes to the left and the right of the axial position to form an axial range if the deformation is greater than or equal to the deformation position corresponding to the threshold value, listing the shell into an area to be adjusted along the area of the axial range, and listing the remaining areas into areas which do not need to be adjusted; the winding process parameters of the next layer is adjusted at the deformation position of the area to be adjusted so as to modify the thickness of the next winding layer to compensate the deformation; and machine tool motion parameters are outputted according to the adjusted winding process parameters of the next layer to control the winding process of the next winding layer.

Description

technical field [0001] The invention relates to the field of solid rocket motors, and provides a real-time winding and forming device for a soft drug column mandrel with drug compound shell, in particular to an integrated forming control device for a soft drug column mandrel, an engine case and a nozzle. Background technique [0002] Traditional engine composite shell and nozzle molding technology uses metal or other materials to wind the hard mandrel to prepare the composite shell. After removing the mandrel, refer to the manufacturing process of the metal shell, and then install the liner, heat insulation layer, and powder column. , hanging parts, etc., but the production process is complicated, which is not convenient for automatic production transformation; out of the need to simplify the process and facilitate automatic production, an integrated winding molding method using viscoelastic powder as the core mold for the shell is proposed, but There are mainly the followin...
