Abstract

The invention relates to a rubber winding forming technology, in particular to an adhesive tape deviation correcting method for winding forming of a heat insulation layer. The method can meet the requirement of deviation correcting of winding forming of a rubber heat insulation layer of a solid rocket engine, and the quality of winding forming of the heat insulation layer is ensured. When a winding pressing roller rotates by a given winding angle, a deviation correcting roller is synchronously controlled to rotate by a corresponding angle in the opposite direction, and the adhesive tape deviation trend is restrained. Due to adhesive tape deviation caused by uneven adhesive tape sections, the geometrical shape and the mounting error of a guide roller, irregular adhesive tape reels, adhesive tape movement and vibration in the automatic winding process and other reasons, the adhesive tape deviation condition is detected in real time, adhesive tape position deviation information is calculated, the rotation angle of the deviation correcting roller is finely adjusted on the basis of the original deviation correcting angle, and the adhesive tape winding position is ensured. The method can meet the requirements of deviation correcting of winding forming of the rubber heat insulation layers of solid rocket engines in different types.

Description

technical field [0001] The invention relates to rubber winding molding technology, in particular to a method for correcting the deviation of a solid rocket motor thermal insulation layer winding molding tape. Background technique [0002] At present, solid rocket motor shells are generally manufactured by using EPDM rubber insulation inner layer and composite material winding shell. The molding methods of EPDM rubber insulation layer mainly include artificial patch method and winding molding method. During the winding and forming process of the thermal insulation layer of the solid rocket motor, it is necessary to ensure that the tape winding position is accurate and meet the quality requirements of the thermal insulation layer winding and forming. When the hoop winding method is used, the winding pressure roller needs to rotate at a given winding angle, and the winding pressure roller produces a lateral force component on the tape, which leads to the lateral deviation tren...
