Description

Heat treatment material frame and quenching system suitable for two-end closing-in type gas cylinder liner Technical Field The utility model relates to the technical field of gas cylinder production, in particular to a heat treatment material frame and a quenching system suitable for a gas cylinder liner with two closed ends. Background In the current industrial field, the aluminum alloy has become one of the indispensable important materials in the modern industry due to the excellent performances of light weight, high strength, corrosion resistance and the like, and is widely applied to a plurality of key industries such as aerospace, automobile manufacturing, ship engineering, petrochemical industry, electronic and electric, machining and the like. Aluminum alloy gas cylinders, which are an important member of many aluminum alloy products, also play a vital role in industrial production and daily life, for example, in fire extinguishing systems for storing and releasing fire extinguishing agents, in diving fields for providing respiratory gases for divers, in medical industries for storing and transporting medical gases, in chemical industries for storing and transporting various gas chemicals, etc. However, the performance of aluminum alloy cylinders is largely dependent on the heat treatment process during their manufacture. The heat treatment technology not only can remarkably improve the key performance indexes such as strength, toughness, corrosion resistance and the like of the aluminum alloy gas cylinder, but also can optimize the microstructure structure of the aluminum alloy gas cylinder, thereby ensuring that the gas cylinder has good reliability and safety in actual use. Currently, in the heat treatment technology of aluminum alloy gas cylinders, a cyclic heat treatment method is dominant. The method is mainly characterized in that an aluminum alloy gas cylinder is filled into a material frame, and the whole material frame is clamped and pressed vertically, so that the gas cylinder is kept in a completely fixed state in the whole heat treatment process. The mode can ensure that the gas cylinder is heated uniformly in the heat treatment links such as heating, heat preservation and cooling to the greatest extent, and avoid the uneven performance and internal tissue defects caused by the problems of local overheating or too fast cooling and the like, thereby ensuring that the gas cylinder finally has excellent comprehensive performance including high strength, high toughness and good dimensional stability. However, this approach also has a significant disadvantage, namely that the production efficiency is extremely low. Because the processing speed of the periodic heat treatment furnace is strictly limited by factors such as loading, unloading, temperature uniformity in the furnace and the like, each production period can be completed in a long time, and the requirement of high-efficiency production can not be met obviously under the condition of large-scale industrial production. In order to solve the problem, continuous heat treatment methods are being explored in the industry in recent years, and the aim is to greatly improve the production efficiency of heat treatment of aluminum alloy gas cylinders through continuous production flow. However, at present, most continuous heat treatment furnaces are unreasonable in charging mode, in a quenching link, because the strength of an aluminum alloy gas cylinder is reduced and the hardness is reduced at high temperature, and the cooling stress distribution received in a quenching medium is complex, the unreasonable charging mode is extremely easy to cause the deformation of the gas cylinder, so that the sealing performance and the overall quality of the gas cylinder are affected. In the field of manufacturing aluminum alloy gas cylinders, a gas cylinder liner with two closed ends gradually takes up important positions, and has unique structure and performance advantages. The two ends of the gas cylinder are closed, so that the inner container is more compact and good in tightness when being connected with an external fitting, gas leakage is effectively prevented, meanwhile, when the inner pressure is born, the stress can be better dispersed, the whole pressure bearing capacity of the gas cylinder is enhanced, and the strict requirements of modern industry on the safety and reliability of the gas cylinder are met. However, this particular closed-off configuration also presents certain challenges during the heat treatment process. On the one hand, in the traditional periodic heat treatment method, the performance of the two-end-closed type gas cylinder liner can be ensured, but as described above, the production efficiency is low, and the requirement of mass production is difficult to meet. On the other hand, when the existing continuous heat treatment method is adopted, due to the structural characteristics of the liner, the charging mode is difficult
