[0002] Stainless steel joint casting heat treatment fixtures are specialized tools used in the casting and heat treatment process of stainless steel joints. Their core function is to optimize the microstructure and performance of stainless steel joints by stabilizing and controlling heat treatment conditions. By precisely controlling heat treatment parameters, they eliminate residual stress inside the stainless steel joints, improve the grain structure, and thus enhance their corrosion resistance, strength, and fatigue life. In the fields of chemical, petroleum, and natural gas, stainless steel joints need to withstand high temperatures, high pressures, and corrosive media for a long time. Heat treatment fixtures directly ensure the safety and reliability of equipment by optimizing joint performance.

[0003] Heat treatment fixtures for stainless steel joint casting ensure uniform heating and cooling during heat treatment, and smooth flow of furnace gas atmosphere, thereby guaranteeing heat treatment quality. For parts requiring localized heat treatment, the fixtures ensure correct control of the heat treatment location; in chemical heat treatment, they ensure uniform diffusion or provide protection. Using heat treatment fixtures allows for efficient furnace loading, maximizing equipment utilization and saving auxiliary time on loading and unloading parts, thus improving labor productivity. Fixtures are also an effective method for controlling deformation of stainless steel joints during heat treatment. For example, fixtures used in processes such as shaping tempering and pressure quenching can reduce deformation of parts during heat treatment. However, assembling heat treatment fixtures requires multiple connectors and kits to combine and fix multiple assembly blocks, which consumes considerable time and effort, thus reducing the assembly effect of the heat treatment fixtures.

[0020] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a stacked assembly structure for a stainless steel joint casting heat treatment fixture, including a base 1, assembly blocks 2 and a cover plate 3. There are multiple assembly blocks 2 and they are evenly distributed on the top of the base 1. The cover plate 3 is located on the top of the assembly blocks 2 and fits against the top of the assembly blocks 2. The inner cavity of the cover plate 3 is provided with a locking mechanism 4 that works with the top assembly blocks 2. The left and right sides of the top of the cover plate 3 are provided with lifting mechanisms 5 that work with the cover plate 3.

[0021] Specifically, the locking mechanism 4 can quickly combine and fix the base 1, multiple assembly blocks 2 and cover plate 3, avoiding the situation where multiple assembly blocks 2 cannot be quickly assembled and fixed. After the assembly blocks 2 are assembled, they can be used in conjunction with the hoisting mechanism 5 and hoisting equipment to achieve the effect of driving the whole tooling for use.

[0022] Furthermore, multiple assembly blocks 2 are sequentially connected to the base 1. After stacking and connecting, the cover plate 3 is connected and fitted to the top assembly block 2. After the connection is made, the locking mechanism 4 can be used to apply downward pressure to the cover plate 3, thereby completing the rapid assembly of multiple assembly blocks 2.

[0023] Example 2 The second embodiment of this utility model provides a stacked assembly structure for a stainless steel joint casting heat treatment fixture. The locking mechanism 4 includes a turntable 501, a connecting rod 502, a threaded rod 503, and a locking block 504. The turntable 501 is located at the top of the cover plate 3, the connecting rod 502 is located at the bottom of the turntable 501 and is fixedly connected to the bottom of the turntable 501, the surface of the connecting rod 502 is rotatably connected to the inner wall of the cover plate 3, the threaded rod 503 is located at the bottom of the connecting rod 502 and is fixedly connected to the bottom of the connecting rod 502, and the locking block 504 is located at the top assembly block 2. The inner cavity is fixedly connected to the inner wall of the assembly block 2. The surface of the threaded rod 503 is connected to the inner cavity of the locking block 504 by threads. The four sides of the top of the base 1 are fixedly connected to the mating rod 7. The surface of the mating rod 7 is inserted and fitted into the inner cavity of the assembly block 2. The four sides of the inner cavity of the cover plate 3 are inserted and fitted into the top surface of the mating rod 7. The top of the mating rod 7 is horizontally aligned with the bottom of the insertion plate 502. The inner cavity of the bottom assembly block 2 is fixedly connected to the cylindrical block 9. The bottom of the top assembly block 2 is fixedly connected to the cylindrical rod 10. The bottom of the cylindrical rod 10 is inserted and fitted into the inner cavity of the cylindrical block 9.

[0024] Specifically, the locking mechanism 4 facilitates the user to quickly assemble and fix multiple assembly blocks 2 with the base 1 and the cover plate 3, avoiding the need to spend a long time to stack and fix multiple assembly blocks 2.

[0025] Furthermore, multiple assembly blocks 2 are sequentially mated to the base 1. During the stacking and mating process, the perimeter of the assembly blocks 2 needs to be inserted and fitted against the surface of the mating rod 7. During the sequential mating of multiple assembly blocks 2, the cylindrical rod 10 needs to be inserted into the inner cavity of the cylindrical block 9. After mating, the cover plate 3 is mated and fitted against the top assembly block 2. During the mating process, when the bottom of the threaded rod 503 contacts the top of the locking block 504, the turntable 501 is rotated. The turntable 501 will drive the connecting rod 502 to rotate. During rotation, the connecting rod 502 drives the threaded rod 503 to connect with the threaded part of the inner cavity of the locking block 504. When the threaded rod 503 moves to the bottom of the inner cavity of the locking block 504, the cover plate 3 and the top assembly block 2 are locked and positioned by the turntable 501, the connecting rod 502, the threaded rod 503 and the locking block 504. Thus, through the cooperation between the cover plate 3 and the locking mechanism 4, the cover plate 3 forms downward pressure, thereby completing the locking and fixing of multiple assembly blocks 2 after docking.

[0026] Example 3 The second embodiment of this utility model provides a stacked assembly structure for a stainless steel joint casting heat treatment fixture. The hoisting mechanism 5 includes a support block 601, a plug-in plate 602, and a hoisting block 603. The support block 601 is located on top of the cover plate 3 and is fixedly connected to the top of the cover plate 3. The plug-in plate 602 is located on top of the support block 601 and is fixedly connected to the top of the support block 601. The hoisting block 603 is located on top of the plug-in plate 602 and is fixedly connected to the top of the plug-in plate 602. The hoisting block 603 is used in combination with hoisting equipment. The top of the connecting rod 7 is provided with a connecting groove 8, and the bottom of the plug-in plate 602 is inserted and fitted into the inner wall of the connecting groove 8.

[0027] Specifically, the hoisting mechanism 5 enables multiple assembly blocks 2 to be quickly transported and used through hoisting equipment, thus avoiding the situation where the overall tooling cannot be quickly used.

[0028] Furthermore, during the docking process between the cover plate 3 and the top assembly block 2, the plug-in plate 602 will be inserted into the inner cavity of the docking groove 8 through the protruding end at the bottom, thereby achieving the effect of stabilizing the cover plate 3 and the assembly block 2. The lifting end of the hoisting equipment can then dock with the lifting block 603. After docking and fitting, it can be connected and fixed by bolt assembly or positioning pin. After fixing, the hoisting equipment and the lifting block 603 can cooperate to quickly achieve the effect of quickly hoisting and using the entire tooling through the cooperation of the plug-in plate 602 and the support block 601 with the cover plate 3.

[0029] Working principle: Multiple assembly blocks 2 are sequentially mated to the base 1. During the stacking and mating process, the four sides of the assembly blocks 2 need to be inserted and fitted with the surface of the mating rod 7. During the sequential mating of multiple assembly blocks 2, the cylindrical rod 10 needs to be inserted into the inner cavity of the cylindrical block 9. After the mating is completed, the cover plate 3 is mated and fitted with the top assembly block 2. During the mating process, when the bottom of the threaded rod 503 contacts the top of the locking block 504, the turntable 501 is rotated. The turntable 501 will drive the connecting rod 502 to rotate. During the rotation of the connecting rod 502, the threaded rod 503 will be threadedly connected to the threaded part of the inner cavity of the locking block 504. When the threaded rod 503 moves to the bottom of the inner cavity of the locking block 504, the cover plate is secured by the turntable 501, the connecting rod 502, the threaded rod 503, and the locking block 504. The cover plate 3 and the top assembly block 2 are locked and positioned. Through the cooperation of the cover plate 3 and the locking mechanism 4, the cover plate 3 forms downward pressure, thereby completing the locking and fixing of multiple assembly blocks 2 after docking. During the docking process between the cover plate 3 and the top assembly block 2, the plug plate 602 will be inserted into the inner cavity of the docking groove 8 through the protruding end at the bottom, thereby achieving the effect of stable fit between the cover plate 3 and the assembly block 2. The lifting end of the hoisting equipment can then be docked with the lifting block 603. After docking and fitting, it can be connected and fixed by bolt assembly or positioning pin. After fixing, the hoisting equipment and the lifting block 603 can cooperate to achieve the effect of quickly hoisting and using the entire tooling through the cooperation of the plug plate 602 and the support block 601 with the cover plate 3.

[0030] In summary, through the cooperation of the base 1, assembly block 2, cover plate 3, locking mechanism 4 and hoisting mechanism 5, the effect of quickly assembling and fixing multiple assembly blocks 2 is achieved.
