[0026] Working principle: The main function of the annealing tool for special-shaped blind hole cylinder forgings is to provide a stable heat treatment environment for the special-shaped cylinder parts after forging, so as to eliminate internal stress, improve mechanical properties and enhance the toughness and ductility of the material. The tooling is needed to accommodate the special-shaped blind hole cylinder forgings to ensure their stability during the heating and cooling process, and then uniformly heat them to the specified annealing temperature to ensure that the entire workpiece can reach the target temperature. The tooling material has good thermal conductivity and high temperature resistance. The structural materials set inside the first restraint 1 and the second restraint 2 have good thermal conductivity and high temperature resistance to ensure that they will not deform during high-temperature annealing. The second restraint 2 can move left and right on the top of the first restraint 1, so that the extension area of ​​the two can be adjusted to facilitate the storage of the second restraint 2.

The practicality of the annealing tool is improved through this structure. The storage block 5 and the binding frame 7 are connected by an L-shaped storage plate 6. As the storage block 5 moves, the L-shaped storage plate 6 will also move synchronously. One side of the binding frame 7 and the second binding member 2 are limited and supported by two reinforcing ribs 13, thereby enhancing the stability of the movement of the second binding member 2. After the second binding member 2 and the first binding member 1 are accommodated, one end of the two limiting strips 12 is embedded in the corresponding limiting hole 10, and the two are threadedly connected, so that the first binding member 1 and the second binding member 2 can be limited and fixed, thereby ensuring the firmness of the second binding member 2.
