[0021] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.
[0022] This embodiment proposes a ring-shaped product nitriding anti-dumping tool, the structure of which is as follows: Figure 1 and 2 As shown, it mainly includes a hook 1, a column 2, a protective rod 3 and a chassis 4.
[0023] The chassis 4 has a honeycomb structure, which can ensure the effective circulation of the nitriding atmosphere during the nitriding treatment. The bottom of the column 2 is welded and fixed to the center of the chassis 4. The column 2 and the chassis 4 jointly determine the available nitriding heat treatment space. There are three protective rods 3. The bottom of each protective rod 3 is connected to the chassis 4 by a thread and is evenly distributed relative to the center of the chassis 4. The protective rod 3 is used to limit the stacking height of the annular product and protect the product. The column 2 cooperates with the protective rod 3 to prevent the gear ring from tipping over, and to ensure the quantity requirements during the production of the gear ring, as well as the safety and design performance requirements of the product during the production process. A hook 1 is installed at the top of the column 2, which is used to lift the tooling and move it into the nitriding furnace.
[0024] like Figure 3 As shown, during the nitriding heat treatment, the gear rings are stacked in three layers in an equilateral triangle. Protective rods 3 are installed so that the outer ring of the gear ring is close to the column 2 and the inner ring of the gear ring is close to the protective rod 3. The gaps between the outer ring of the gear ring and the column 2, and between the inner ring of the gear ring and the protective rod 3, are both ≤5mm, preventing the gear ring from tipping over and ensuring safe nitriding production. The gear ring is lifted by hook 1 and moved into the pit nitriding furnace for nitriding treatment.
[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
