Abstract

The invention discloses a method for preventing and controlling redundant objects in narrow gap structures. The method comprises the following steps: heating and melting water-soluble wax, pouring wax liquid into the narrow gap to be filled; using paste-like adhesive wax to seal the product and The gap between the joints between the water-soluble wax; the surface of the water-soluble wax is covered with a medium-temperature wax liquid; the paste-like bonding wax is used to seal the gap between the product and the water-soluble wax; compressed air is used to remove metal shavings and other excess on the product surface, and ultrasonic cleaning Remove oil stains on the surface of the product; use an electric steam dewaxing furnace to remove the medium temperature wax, bonding wax and part of the water-soluble wax in the product; for the product after dewaxing, use compressed air to blow off the residual wax in the inner cavity, and use Use a soft brush to remove residual wax on the surface; boil to remove residual water-soluble wax in the gap; place the product in alcohol for ultrasonic cleaning; use a vacuum oven for drying. The invention solves the problem that traditional animal fats are difficult to remove.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for preventing and controlling excess objects in a narrow gap structure. Background technique [0002] The liquid rocket engine is the core device of the launch vehicle and missile weapon, with complex system composition and harsh working environment, it is the most complex power system at present. At the same time, with the continuous improvement of the demand for liquid power systems and the further improvement of parameters such as the thrust-to-mass ratio and specific impulse of the engine, higher requirements are put forward for the lightweight, high reliability and high performance of the power system, which makes the liquid rocket engine The structure of the core components of the power system is more complex, and the multi-material, multi-structure, and multi-process composite manufacturing is more obvious. There are a large number of na...
