Dismounting device and method for heat insulation forming ring of solid rocket engine

Abstract

The invention provides a solid rocket engine heat insulation forming ring dismounting device and a dismounting method.The dismounting device comprises a rack, a mounting base is arranged on the rack, a mounting frame is arranged on the mounting base, a telescopic mechanism is arranged on the mounting frame, a dismounting claw support is arranged at the telescopic end of the telescopic mechanism, and dismounting claws are arranged on the dismounting claw support; a sliding ring matched with the dismounting claw support is arranged at the tail end of the dismounting claw, the sliding ring is fixed to the dismounting claw support through a puller bolt, a clamping protrusion is arranged at the front end of the dismounting claw, and a plurality of puller rods are arranged on the mounting frame. According to the dismounting device and the dismounting method, the solid rocket engine curing forming ring can be quickly dismounted, the labor intensity of operators is reduced, and the dismounting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing a solid rocket motor thermal insulation layer, in particular to a disassembly device and a disassembly method for a solid rocket motor thermal insulation forming ring. Background technique [0002] When assembling the solid rocket motor casing and the nozzle, it is necessary to ensure that the size of the insulation layer steps in the opening of the casing meets the design requirements. When forming the inner insulation step of the solid rocket motor, the generally used process is to design a matching metal step forming ring. During the pressurization of the insulation layer, the inner insulation material flows along the size of the forming ring, and forms a suitable size after vulcanization. In the vulcanization process of the thermal insulation material, it will be closely matched with the steps of the thermal insulation forming ring, and it is difficult to disassemble. [0003] There are...

Problems solved by technology

However, during the vulcanization process of the heat insulation material, it will be closely matched with the steps of the heat insulation forming ring, making it difficult to disassemble

[0003] Generally, two methods are used to disassemble the forming ring. One is to use a copper hammer to extend into the inner side of the forming ring from the rear opening, and disassemble the forming ring by knocking. Hidden danger

Another kind of dismantling and ejecting ring is matched with the design, but if there is no suitable screw hole on the open end of the shell, this method cannot be used
