[0003] In the heat treatment process of rivets, a heat treatment device for homogenizing the internal stress of the rivets is required. A search revealed a patent document with publication number CN221397952U, which discloses a heat treatment device for rivet processing. This device includes a heating chamber with a support frame fixedly connected to the top. A stirring mechanism is mounted on the support frame. A cooling chamber is connected to one side of the heating chamber, and a control mechanism is located between the heating chamber and the cooling chamber. A partition is fixedly connected to one end of the control mechanism, and a cleaning mechanism is located on the other side of the heating chamber. This invention allows observation of the rivet's condition during heating by opening the connecting cover, preventing overheating or underheating from affecting the rivet's quality. A filter screen at the bottom of the cooling chamber filters the cooling water into a storage tank.
[0004] However, the heat treatment equipment for rivet processing in this utility model is a fixed heating type, which cannot make the rivet heat evenly during the heating process. This results in uneven stress distribution inside the rivet, which cannot achieve the ideal heat treatment effect and seriously affects the performance and service life of the rivet, failing to meet production needs. Therefore, a heat treatment equipment for homogenizing the internal stress of rivets is proposed to solve the problems mentioned above. Utility Model Content

It has the advantages of stress homogenization and strong practicality. It solves the problem that existing heat treatment equipment for rivet processing is a fixed heating type, which cannot make the rivets heat evenly during the heating process. This results in uneven distribution of internal stress in the rivets, which cannot achieve the ideal heat treatment effect, seriously affecting the performance and service life of the rivets and failing to meet production needs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for homogenizing internal stress of rivets, including a heat treatment box, a heat soaking plate fixedly installed inside the heat treatment box, and a sealed door hinged to the outside of the heat treatment box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 3 The internal stress homogenization heat treatment equipment for rivets in this embodiment includes a heat treatment box 1, a heat soaking plate 2 fixedly installed inside the heat treatment box 1, and a sealing door 3 hinged to the outside of the heat treatment box 1. A rotating mechanism extending into the outside of the heat treatment box 1 is provided.
[0023] The rotating mechanism includes a drive motor 6 fixedly mounted on the back of the heat treatment chamber 1, a worm gear 7 fixedly connected to the output shaft of the drive motor 6, a rotating shaft 9 rotatably connected to the inside of the heat treatment chamber 1 and extending to its outside, a worm wheel 8 fixedly connected to one end of the rotating shaft 9, a rotating seat 10 fixedly connected to the outside of the rotating shaft 9, and a placement box 11 fixedly connected to the outside of the rotating seat 10.
[0024] The drive motor 6 is fixedly mounted on the back of the heat treatment chamber 1 by bolts, and the interior of the heat treatment chamber 1 is fixedly mounted with a bearing that is compatible with the rotating shaft 9.
[0025] Specifically, the drive motor 6 is electrically connected to the controller 5, and the worm 7 and worm wheel 8 are meshed together. There are four placement boxes 11, arranged in a ring around the outside of the rotating base 10. All four placement boxes 11 and the rotating base 10 are rotatably connected to the interior of the heat spreader 2. The controller 5 starts the drive motor 6, causing the worm 7 to rotate. The worm 7 meshes with the worm wheel 8, which in turn drives the rotating base 10 to rotate synchronously via the rotating shaft 9. This causes the rivets placed inside the placement boxes 11 to rotate as well. The controller 5 activates the heat spreader 2 to heat the rotating rivets. Because the rivets continuously change position during rotation, uniform heating is achieved, resulting in the advantage of stress homogenization.
[0026] It should be noted that a cover plate 12 is detachably installed on the outside of the storage box 11. A handle 13 is fixedly connected to the outside of the cover plate 12. A locking block extending into the interior of the storage box 11 is fixedly connected to the bottom of the cover plate 12. The interior of the storage box 11 has a locking groove that matches the locking block, and the locking block and the locking groove are engaged. The engaging structure allows the cover plate 12 to be easily and quickly connected or separated from the storage box 11 without the need for complex locking buckles or bolts, thus improving operational efficiency. The handle 13 allows users to easily lift and move the cover plate 12. The tight fit between the locking block and the locking groove effectively prevents external dust, moisture, and other impurities from entering the interior of the storage box 11, protecting the internal rivets from contamination.
[0027] In this embodiment, a heat dissipation mechanism is provided on the outside of the heat treatment chamber 1. The heat dissipation mechanism includes a mounting shell 14 fixedly installed on the outside of the heat treatment chamber 1 and a cooling fan 15 rotatably installed inside the mounting shell 14. By starting the cooling fan 15 through the controller 5, heat can be effectively transferred from the inside of the heat treatment chamber 1 and accelerated to the air by the cooling fan 15, thereby protecting the internal components from high temperature damage.
[0028] The heat treatment chamber 1 is externally fixedly connected with two fixing seats 4, which are distributed sequentially on the outside of the heat treatment chamber 1.
[0029] The working principle of the above embodiments is as follows:
[0030] In use, the rivets are placed inside the placement box 11 and the cover plate 12 is closed. The controller 5 starts the drive motor 6, which drives the worm gear 7 to rotate. The worm gear 7 meshes with the worm wheel 8, and the rotating shaft 9 drives the rotating seat 10 to rotate synchronously, so that the rivets placed inside the placement box 11 also rotate. The controller 5 starts the heat spreader 2 to heat the rotating rivets. The temperature control system controls the working state of the heat spreader 2 according to the preset temperature and time parameters to ensure that the heat treatment process achieves the predetermined effect. Since the rivets constantly change position during rotation, a uniform heating effect is achieved. The controller 5 starts the cooling fan 15, which can effectively remove heat from the inside of the heat treatment box 1 and accelerate its dissipation into the air, thereby protecting the internal components from high temperature damage.
[0031] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.
[0032] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
