[0019] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0020] Please refer to the attached Figure 1-5 As shown in the figure, a high-speed steel circulating water bath annealing tube provided by the present utility model includes an annealing tube 1 and high-speed steel 2, and further includes a circulating component for driving the annealing tube 1 to rotate 180 degrees in both forward and reverse directions. One end of the annealing tube 1 is provided with a high-temperature water bath component, and the middle of the annealing tube 1 is provided with a cooling component. The circulating component is arranged at the other end of the annealing tube 1. The high-speed steel 2 sequentially passes through the high-temperature water bath component and the cooling component, and the high-speed steel 2 passes through the inside of the annealing tube 1;

[0021] The circulating component includes two supports 3, which are respectively located at both ends of the annealing tube 1. Ring-shaped rotating frames 4 are fixed on the tops of the two supports 3. The outer surfaces of both ends of the annealing tube 1 are respectively rotatably connected to the inner surfaces of the two ring-shaped rotating frames 4 through turntable bearings 5, that is, the annealing tube 1 can rotate on the support 3. A ring-shaped rack 6 is also fixed on the outer surface of the annealing tube 1. A motor base 7 is fixed below the annealing tube 1, and a servo motor 8 is fixed on the top of the motor base 7. A transmission gear 9 is fixed on the output shaft of the servo motor 8, and the transmission gear 9 meshes with the ring-shaped rack 6. Specifically, when the servo motor 8 operates, it can rotate through the transmission gear 9, and then drive the annealing tube 1 to rotate 180 degrees in both forward and reverse directions by driving the ring-shaped rack 6;

[0022] The high-temperature water bath assembly includes two water bath tanks 10, which are symmetrically fixed on the upper and lower surfaces of the end of the annealing tube 1. At the end of each water bath tank 10 away from the annealing tube 1, a water inlet pipe 11 is fixedly connected. An inlet valve 12 is arranged on the body of the water inlet pipe 11. At the end of each water inlet pipe 11, a water inlet hose 13 is fixedly connected. At the end of each water inlet hose 13 away from the water inlet pipe 11, a makeup water pump (not shown in the figure) is fixedly connected. That is, the makeup water pipe can supplement the required water into the water bath tank 10 through the water inlet hose 13, and the length of the water inlet hose 13 is sufficient to adapt to the position change of the water bath tank 10 that rotates 180 degrees in the forward and reverse directions with the annealing tube 1. An electric heating rod 14 is fixedly arranged in each water bath tank 10. That is, when the electric heating rod 14 operates, heat energy can be generated to heat the water in the water bath tank 10 into high-temperature water. A number of water leakage holes 15 are opened at the end of each water bath tank 10 close to the annealing tube 1. A liquid level gauge 16 is fixedly connected to the side of each water bath tank 10, which is convenient for technicians in the field to understand the liquid level change in the water bath tank 10 in real time;

[0023] On the inner surface of the end of the annealing tube 1, water collecting ports 17 are symmetrically arranged up and down. The two water collecting ports 17 correspond to the ends of the two water bath tanks 10 close to the annealing tube 1. A number of water leakage holes 15 are communicated with the corresponding water collecting ports 17. A first annular partition 18 and a second annular partition 19 are also fixedly arranged on the inner surface of the annealing tube 1. The first annular partition 18 and the second annular partition 19 can play the functions of heat preservation and water separation. The first annular partition 18 and the second annular partition 19 are symmetrically distributed on both sides of the water collecting port 17. The high-speed steel 2 passes through the first annular partition 18 and the second annular partition 19 in sequence. Exhaust pipes 20 are symmetrically and fixedly connected to the upper and lower ends of the first annular partition 18, which can be used to discharge water vapor. Specifically, as the two water bath tanks 10 that rotate 180 degrees in the forward and reverse directions of the annealing tube 1 can alternately change their upper and lower positions, the high-temperature water in the upper water bath tank 10 is sprayed downward through the upper water leakage holes 15 to heat the high-speed steel 2. The sprayed water can flow into the lower water bath tank 10 through the lower water leakage holes 15 and the water collecting ports 17, so as to realize the function of circulating water bath of the high-temperature water in the water bath tank 10 for the high-speed steel 2. There is no need for a circulation pump, effectively avoiding the phenomenon that the circulation pump is easily damaged frequently due to high temperature during use, and greatly improving the annealing efficiency of the high-speed steel;

[0024] The cooling assembly includes a cold water pipe 21 which is horizontally arranged below the annealing pipe 1. The input end of the cold water pipe 21 is fixedly communicated with a cold water hose 22. One end of the cold water hose 22 away from the cold water pipe 21 is fixedly connected to a water pump (not shown in the figure). That is, when the water pump operates, it can continuously supply the required cooling water into the cold water pipe 21, and the length of the cold water hose 22 is sufficient to adapt to the position change of the cold water pipe 21 which rotates 180 degrees forward and backward along with the annealing pipe 1. A plurality of water delivery pipes 23 are vertically and fixedly communicated with the pipe body of the cold water pipe 21. The tops of the plurality of water delivery pipes 23 all penetrate through the annealing pipe 1, and the tops of the plurality of water delivery pipes 23 are all fixedly communicated with an annular water pipe 24. A plurality of spray heads 25 are fixedly communicated with the inner side of the annular water pipe 24 in a circular array. The high-speed steel 2 sequentially passes through a plurality of annular water pipes 24. Specifically, the high-speed steel 2 after high-temperature heating can be sprayed with cooling water by a plurality of spray heads 25 on the annular water pipe 24 for cooling, so as to perform annealing treatment on the high-speed steel 2.

[0025] It should be noted that the present utility model is electrically connected to an external main controller and 220V mains electricity, and the main controller can be an existing technical device such as a computer for control.

[0026] The using process of the present utility model is as follows: When in use, those skilled in the art first add the required water into the water bath tank 10 through a make-up water pump, then heat the water in the water bath tank 10 through the electric heating rod 14, control the operation of the servo motor 8, control the annealing pipe 1 to rotate 180 degrees forward and backward in a cycle, then continuously supply the required cooling water to the cold water pipe 21 through a water pump, and then pass the high-speed steel 2 through the annealing pipe 1. The two water bath tanks 10 that rotate 180 degrees forward and backward along with the annealing pipe 1 can alternately change their upper and lower positions, so that the high-temperature water in the upper water bath tank 10 is sprayed downward through the upper water leakage holes 15, thereby heating the high-speed steel 2, and the sprayed water can flow into the lower water bath tank 10 through the lower water leakage holes 15 and the water collection ports 17, so as to realize the function of circulating water bath of the high-temperature water in the water bath tank 10 for the high-speed steel 2. The high-speed steel 2 after high-temperature heating can be sprayed with cooling water by a plurality of spray heads 25 on the annular water pipe 24 for cooling, so as to perform annealing treatment on the high-speed steel 2. In summary, the present utility model does not require a circulation pump to realize the function of circulating water bath of high-temperature water, effectively avoiding the phenomenon that the circulation pump is easily damaged frequently due to high temperature during use, and greatly improving the annealing efficiency of high-speed steel.

[0027] The above are only the preferred embodiments of the present utility model. Any person skilled in the art can modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model all fall within the scope of protection required by the present utility model.
