TECHNICAL FIELD
[0001] The utility model relates to a material frame field, especially in the stress damage of a material frame in heat treatment process. BACKGROUND
[0002] The material frame for heat treatment is a storage container used for loading and transporting parts in metal heat treatment process. The main function of the heat treatment material frame is to facilitate the material to be put into and taken out of the heat treatment environment, such as heating furnace, cooling tank, etc. In the heat treatment process, the material may need to be heated, cooled and temperature maintained at different temperatures, and the material frame can effectively protect the material from damage by the external environment, and facilitate loading and unloading and transportation operation, and improve production efficiency. The material frame is usually made of metal, and the metal has the characteristics of thermal expansion and contraction. In the heat treatment process, the material frame will be subjected to the alternating action of high temperature and low temperature, thereby generating thermal stress. In the heating and cooling process, the temperature difference of each part of the material frame will cause the generation of thermal stress. Especially when the size of the material frame is large or the shape is complex, the temperature difference will be more obvious, thereby increasing the influence of thermal stress. In the process of multiple heat treatments, the thermal stress will continue to accumulate, and when it accumulates to a certain extent, the material frame may be damaged, such as plastic deformation or cracking. And in the heat treatment process, different sizes of workpieces placed in the material frame are easy to collide, thereby easily causing damage to the workpieces, so a material frame resisting stress damage in heat treatment process is needed to solve the above problems.
