Description

Ammunition nursing system Technical Field The invention belongs to the technical field of civil blasting equipment, and relates to a nursing system for ammunition. Background In the field of military equipment, ammunition is used as a core combat material, and the storage reliability and the use safety of the ammunition directly influence the combat effectiveness. The ammunition is charged by adopting a fusion-cast explosive, the stability of the charging structure is ensured through a scientific nursing process in the casting molding and subsequent storage and transportation processes, the quality defects of air holes, shrinkage cavities, cracks and the like caused by factors such as temperature change, stress concentration and the like are avoided, and the safety risk in the use process of the ammunition is reduced. The heat preservation nursing can optimize the solidification process of the powder charge, gradient cooling can relieve internal stress generated by thermal expansion and cold contraction, accurate monitoring of an internal temperature field and the powder charge state of the elastomer is a key precondition for realizing personalized nursing, and the three cooperate to form a core technical system for nursing the powder charge. However, there are still a number of technical bottlenecks in the existing ammunition care process. On one hand, the integrated cooperative mechanism of thermal insulation monitoring and gradient cooling is lacking, the traditional nursing is carried out step by taking thermal insulation, monitoring and cooling as independent links, the problem of overlarge temperature fluctuation easily occurs in the link switching process, and further deformation of a charging structure is caused, on the other hand, the monitoring accuracy of an internal temperature field and a charging state of a projectile body is insufficient, the traditional monitoring means is mainly external temperature measurement or rough internal detection, the temperature difference and the charging solidification progress of different areas inside the projectile body are difficult to capture, and accurate basis cannot be provided for nursing parameter adjustment, in addition, the projectile body deformation risk in the nursing process is high, particularly, small-sized, thin-walled projectile bodies or accurate fuze parts are easy to generate irreversible deformation due to uneven stress or concentrated thermal stress in the clamping and fixing and temperature change processes, and the performance of the projectile body is influenced. Through searching, the invention patent with the publication number of CN118209007A discloses a gradient temperature control nursing device for large-scale air shells, the sequential solidification nursing of the air shells is realized by adopting the design of a plurality of sections of independent cabins through the cooperation of a positioning mechanism and a circulating system, the core principle is that the gradient temperature adjustment is realized by utilizing the joint arrangement of a jacket and the air shells and through the independent temperature control heat source, the quality defects of air holes, shrinkage holes and the like of the charge shells can be effectively solved, and the device has the advantages of compact structure and high automation level. The technology has obvious defects that the internal nursing effect cannot be accurately obtained only by focusing on external echelon temperature control and not directly monitoring the internal temperature field and the charging state of the projectile body, meanwhile, the adaptability of a clamping and temperature control structure is limited, the nursing requirements of small-sized and thin-wall projectile bodies are difficult to meet, an integrated cooperative flow of heat preservation, monitoring and cooling is not formed, and the temperature fluctuation control effect is poor. In addition, the traditional nursing technology also comprises modes of manual monitoring combined with sectional cooling, single medium circulation temperature control and the like, and the problems of low automation degree and poor nursing efficiency exist in the methods, or the problem that the nursing parameter matching degree is insufficient due to lack of targeted monitoring, so that pain points in the prior art cannot be comprehensively solved. Therefore, there is a need for an integrated ammunition care system integrating thermal insulation care, internal accurate monitoring and gradient cooling functions, which realizes the accuracy, synergy and high efficiency of the care process. Disclosure of Invention The invention provides an ammunition nursing system, which solves the technical problems that the existing ammunition nursing lacks a heat preservation monitoring and gradient cooling integrated cooperative mechanism, the monitoring accuracy of an internal temperature field and a charging state of an ammunition is insuffi
