[0036] In a specific embodiment of the present utility model, the barrel-shaped permeation box 1 serves as the main container of the entire boronizing strengthening device. Its main function is to accommodate the boronizing medium and the steel pipe plug to be processed. The shape and size of the barrel-shaped permeation box 1 are designed considering materials that can withstand high temperatures and chemical reactions to ensure safety and efficiency during the boronizing process. The placement groove 2 is located at the upper end of the barrel-shaped permeation box 1 and is used to fix and position the inner cover 3 of the permeation box. The structure of the placement groove 2 ensures the tight fit of the inner cover, prevents the leakage of the boronizing medium, and also facilitates the installation and removal of the inner cover. The inner cover 3 of the permeation box is placed in the placement groove 2. Its function is to seal the top of the barrel-shaped permeation box 1, prevent external air from entering, and cooperate with the first nut 4 and the first bolt 5 to ensure the sealing of the permeation box, creating a sealed high-temperature environment for the boronizing process. The first nut 4 is fixedly connected to the inner cover 3 of the permeation box and is used in conjunction with the first bolt 5 to fasten the inner cover and ensure the sealing of the permeation box during the boronizing process. By adjusting the tightening degree of the first bolt 5, the sealing pressure of the inner cover 3 of the permeation box can be controlled to ensure that the boronizing medium does not leak. The asbestos board 6 is connected to the upper end of the barrel-shaped permeation box 1. Its function is to provide an additional heat insulation layer, reduce heat energy loss, and maintain the high-temperature environment inside the permeation box. The use of the asbestos board 6 can also prevent the top cover 7 of the permeation box from overheating and protect the safety of the operator. The top cover 7 of the permeation box is connected to the upper end of the asbestos board 6 and is used to completely enclose the entire boronizing device to prevent heat and boronizing medium from escaping. The design of the top cover 7 of the permeation box needs to consider the convenience of operation, facilitate opening and closing, and also ensure sufficient heat resistance and sealing performance. The fixing bolts 8 are threadedly connected between the barrel-shaped permeation box 1, the asbestos board 6, and the top cover 7 of the permeation box. Their function is to ensure the tight connection between the top cover 7 of the permeation box and the barrel-shaped permeation box 1 and prevent loosening or leakage under high-temperature and high-pressure conditions. The number and distribution of the fixing bolts 8 should ensure uniform force application to maintain the structural stability of the entire device.

[0037] For details, please refer to Figures 1-3 A connecting seat 10 is fixedly connected to the upper end of the top cover 7 of the permeation box. A fixing rod 12 is connected to the connecting seat 10. A second nut 13 is threadedly connected between the connecting seat 10 and the fixing rod 12. An adjusting handle 14 is fixedly connected to the second nut 13.

[0038] In this embodiment: The connecting seat 10 is fixedly connected to the upper end of the lid 7 of the permeation tank. Its main function is to serve as the mounting base for the fixed rod 12 to ensure the stability and positioning accuracy of the fixed rod 12. The design of the connecting seat 10 needs to consider the load-bearing capacity and the connection strength with the lid 7 of the permeation tank to ensure the structural stability of the entire device. The fixed rod 12 is connected to the connecting seat 10. Its role is to provide a lever for operation, facilitating the user to adjust or fix the lid 7 of the permeation tank through the adjusting handle 14. The fixed rod 12 is usually designed as a rod-shaped structure with a certain length to provide sufficient torque, enabling the user to easily operate the second nut 13 to tighten or loosen the lid 7 of the permeation tank. The second nut 13 is threadedly connected between the connecting seat 10 and the fixed rod 12. Its main function is to serve as a fastener to adjust the position of the fixed rod 12 relative to the connecting seat 10 by tightening or loosening, thereby controlling the opening and closing of the lid 7 of the permeation tank. The design of the second nut 13 needs to ensure good thread fit and sufficient fastening force to prevent the lid 7 of the permeation tank from loosening accidentally during use. The adjusting handle 14 is fixedly connected to the second nut 13. Its design purpose is to provide a convenient handle for operation. The user can rotate the adjusting handle 14 to tighten or loosen the second nut 13, thereby realizing the fixing or release of the lid 7 of the permeation tank. The adjusting handle 14 usually has a good grip and sufficient length to provide sufficient torque for convenient operation. Through the coordinated use of the connecting seat 10, the fixed rod 12, the second nut 13, and the adjusting handle 14, the steel pipe plug boron strengthening device in this embodiment can achieve the rapid, accurate, and safe opening and closing of the lid 7 of the permeation tank, greatly improving the convenience and efficiency of operation, and at the same time ensuring the safety and controllability of the boronizing process. This design simplifies the operation process, reduces the operation difficulty, and also improves the reliability and durability of the entire device.

[0039] For details, please refer to Figures 1-3 , the lower end of the barrel-shaped permeation tank 1 is connected to a base 11, and the base 11 is connected to the fixed rod 12.

[0040] In this embodiment: the base 11 is located at the lower end of the barrel-shaped infiltration box 1, and its main function is to provide stable support for the entire device. The design of the base 11 usually takes into account the load-bearing capacity and balance, ensuring that the barrel-shaped infiltration box 1 remains stable during high-temperature operation and chemical reaction, and preventing the risk of tipping due to unstable center of gravity or uneven ground. The base 11 is connected to the fixed rod 12, which means that the fixed rod 12 is not only associated with the infiltration box top cover 7 at the top through the connecting seat 10, but also supported by the base 11 at the bottom. This fixed design at both ends enhances the stability of the fixed rod 12, ensuring that when operating the adjustment handle 14, the fixed rod 12 can withstand the adjustment force without shaking or deformation, thereby improving the structural integrity and operational reliability of the entire device. The connection between the base 11 and the barrel-shaped infiltration box 1 ensures that the base of the entire device is firm, and the connection with the fixed rod 12 further enhances the longitudinal stability of the device. This design is particularly important for boronizing strengthening devices operating in high temperature and high pressure environments, because any slight structural instability may lead to serious safety problems. The presence of the base 11 also provides sufficient space and platform for operators to perform necessary operations at the bottom, such as checking and cleaning the bottom of the seepage box, or moving and positioning the device when necessary. Through the combination of the base 11 with the barrel-shaped seepage box 1 and the fixing rod 12, the steel pipe head boronizing strengthening device in this embodiment not only achieves structural stability and operational convenience, but also ensures safety and efficiency under extreme working conditions, providing a solid foundation for efficiently completing the boronizing strengthening treatment of the steel pipe head.

[0041] For details, please refer to Figures 1-3 A handle 9 is fixedly connected to the upper end of the seepage box top cover 7.

[0042] In this embodiment, the design of the handle 9 greatly facilitates the operator to open or close the seepage box top cover 7. Since the seepage box top cover 7 may be relatively heavy, especially after high temperature treatment, direct contact may cause burns. The handle 9 provides a safe and effective point of force, allowing the operator to easily open and close the top cover, avoiding the danger of direct contact with the high temperature surface.

[0043] For details, please refer to Figures 1-3 A reinforcing rib is fixedly connected between the base 11 and the barrel-shaped seepage box 1 .

[0044] In this embodiment, the reinforcing ribs are designed to improve the structural strength of the connection between the base 11 and the barrel-shaped seepage box 1. During the boronizing strengthening process, the barrel-shaped seepage box 1 is subjected to stress caused by high temperature and chemical reaction. The reinforcing ribs can significantly enhance the rigidity of the connection, prevent deformation or breakage under high temperature and heavy pressure, and ensure the stability and safety of the entire device.

[0045] For details, please refer to Figures 1-3, the top cover 7 of the permeation box is the same size as the asbestos board 6.

[0046] In this embodiment: The asbestos board 6 serves as a heat insulation layer, and its design with the same size as the top cover 7 of the permeation box helps to reduce heat dissipation from the top. The asbestos board 6 can effectively isolate the external environment and maintain the high-temperature state inside the barrel-shaped permeation box 1, thereby improving energy utilization efficiency and boronizing efficiency.

[0047] The working principle and usage process of the present utility model: First, confirm that all components are intact, including the barrel-shaped permeation box 1, the inner cover 3 of the permeation box, the asbestos board 6, the top cover 7 of the permeation box, the fixing bolts 8, etc. Check whether the connecting seat 10, the fixing rod 12, the second nut 13, the adjusting handle 14, and the handle 9 are firm. Confirm that the reinforcing rib connection between the base 11 and the barrel-shaped permeation box 1 is stable. Open the top cover 7 of the permeation box, remove the asbestos board 6 and the inner cover 3 of the permeation box. Place the steel pipe head to be boronized and strengthened into the placement groove 2 inside the barrel-shaped permeation box 1. Cover the inner cover 3 of the permeation box on the placement groove 2 and fix it with the first nut 4 and the first bolt 5. Place the asbestos board 6 on the barrel-shaped permeation box again. Cover the top cover 7 of the permeation box on the asbestos board 6 to ensure that the top cover 7 of the permeation box and the asbestos board 6 fit perfectly. Use the fixing bolts 8 to tightly connect the top cover 7 of the permeation box, the asbestos board 6, and the barrel-shaped permeation box 1. Start the heating device and heat the inside of the barrel-shaped permeation box 1 to the set boronizing temperature. Monitor the temperature and pressure inside the barrel-shaped permeation box 1 through the observation window or sensor to ensure that the boronizing conditions meet the process requirements. Record the boronizing time and parameters for subsequent analysis and quality control. After the boronizing is completed, turn off the heating device and let the barrel-shaped permeation box 1 cool naturally to a safe operating temperature. Carefully open the top cover 7 of the permeation box using the handle 9 and remove the asbestos board 6 and the inner cover 3 of the permeation box.
