A rubber winding molding pressure control device and method belong to the technical field of rubber winding molding. The winding pressure roller in the device is installed on the winding pressure roller support shaft, which is installed on the translation mechanism; the thrust block is installed on one end of the relay platform; the half worm wheel is installed on the winding pressure roller support shaft, and the worm, servo motor Installed in the translation mechanism. The translation mechanism is installed on the translation guide rail, and the translation mechanism translates along the translation guide rail under the drive of the cylinder, and stops at the position of the thrust block. During the winding process, the relay platform is controlled by the numerical control mechanism to move in translation, combined with other kinematic mechanisms of the winding equipment, to ensure the winding position and posture of the winding pressure roller. The invention can ensure the required winding pressure in the rubber winding process and at the same time avoid winding pressure overload; it is suitable for the circumferential winding requirements of the solid rocket motor barrel section and the transition part at both ends of the heat insulation layer, and at the same time meets the requirements of other different types of solid rocket motor barrel sections Automatic winding pressure requirements for rubber insulation.
Description
technical field [0001] The invention relates to the technical field of rubber winding molding, in particular to a pressure control device and method for winding and molding a solid rocket motor thermal insulation layer. Background technique [0002] At present, the solid rocket motor casing is generally manufactured by the method of EPDM rubber thermal insulation inner layer and composite material wrapping the outer casing. The EPDM rubber insulation layer forming methods mainly include manual patch method and winding forming method. The winding pressure directly affects the shape of the solid rocket motor thermal insulation layer and the bonding strength and density of the thermal insulation layer, and is one of the key factors affecting the winding quality of the solid rocket motor thermal insulation layer. If the winding pressure is too small, it will directly affect the bonding strength of the thermal insulation layer; if the winding pressure is too large, the rubber de...
