Description

Technical Field

[0001] This utility model relates to the field of aging furnace technology, specifically to an aging furnace for the production of tube busbars that can efficiently maintain heat. Background Technology

[0002] In the field of high-end metal heat treatment, controlling the process environment is crucial to ensuring the final performance and quality of products in order to achieve efficient production of tubes and busbars. When processing metal materials that are highly sensitive to oxygen, it is essential to construct a protective environment with no oxygen or extremely low oxygen partial pressure. Vacuum technology has become the preferred solution in this context: by evacuating the heating chamber to a high vacuum, the oxygen medium involved in oxidation and decarburization reactions is fundamentally removed. This not only completely avoids the formation of oxide scale and the loss of carbon on the workpiece surface, but also allows it to maintain its bright, original metal surface after heat treatment. This eliminates the need for subsequent secondary processes such as cleaning, sandblasting, or machining to repair surface quality, significantly reducing production costs and time while improving product quality. The hinge structure of the furnace door in a traditional horizontal aging furnace is complex and has limited load-bearing capacity. During the opening of the furnace door, almost all of its enormous weight and the resulting torque are borne by the hinge shaft and hinge seat, causing the hinge system to endure huge concentrated stresses over a long period of time. This condition not only accelerates the fatigue wear of the hinge and significantly shortens its service life, but also potentially poses a safety risk due to structural failure. Utility Model Content

The placement frame is mounted on the fixing plate, and a rotating shaft is movably provided on the placement frame. A rotating gear is provided on the rotating shaft and the rotating gear meshes with the transmission rack. The fixing frame is mounted on the fixing plate, and a movable rack is movably provided on the fixing frame. A rotating gear is provided at the end of the rotating shaft away from the rotating gear, and the rotating gear meshes with the movable rack.

[0007] Preferably, the movable rack is provided with a pull block.

[0008] Preferably, the limiting structure includes a limiting hole and a fixed box. The limiting hole is provided on the movable rack, and the fixed box is mounted on the fixed frame. A sliding plate is movably provided inside the fixed box. A second spring is provided on the sliding plate, and the end of the second spring away from the sliding plate abuts against the inner wall of the fixed box. A moving rod is provided on the sliding plate, and a limiting rod is provided on the side wall of the sliding plate away from the moving rod, and the limiting rod abuts against the limiting hole.

[0009] Preferably, the limiting hole is provided in a plurality of parts.

[0010] Preferably, one of the plurality of adjustment structures includes a connecting frame and a locking hole. The connecting frame is mounted on the heating chamber body, the locking hole is located on the connecting frame, a threaded rod is movably mounted on the connecting frame, an abutment block is movably mounted on the threaded rod, a fixed rod is mounted on the connecting frame and the fixed rod is movably connected to the abutment block, a rotating shaft is movably mounted on the connecting frame, a rotating bevel gear is mounted on the rotating shaft, a rotating plate is mounted on the rotating shaft, a locking rod is movably mounted on the rotating plate and the locking rod abuts against the locking hole, and a rotating bevel gear is located at the end of the threaded rod away from the abutment block and the rotating bevel gear meshes with the rotating bevel gear.

[0011] Preferably, the rotating plate is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are as follows: As an efficient heat-insulating aging furnace for pipeline production, this utility model, through structural adjustment, transforms manual operation into precise lifting and adaptive buffering of the casters. This achieves strong support and stress distribution for the furnace door of the heating chamber. During the opening of the furnace door, the casters reliably contact the ground, directly transferring part of the furnace door's weight to the ground, significantly reducing the static load and dynamic torque borne by the hinge system, thereby effectively extending its service life and improving the overall safety of the equipment. Simultaneously, the integrated spring buffer mechanism gives the casters excellent vertical adaptive capability, enabling them to actively avoid and buffer impacts when encountering uneven ground, ensuring smooth and stable opening and closing of the furnace door without jamming or abnormal stress generation. Ultimately, it achieves a balance between rigid force and flexible adaptation in furnace door support under complex working conditions, greatly improving the reliability of the equipment and the user experience. With the limiting structure, when the moving rack moves to the predetermined position, the mechanism can be automatically triggered by the reset action of the second spring, driving the limiting rod to accurately embed into the rack limiting hole, forming a rigid mechanical interlock, thereby achieving reliable fixation of the end of the transmission chain and effectively preventing rack displacement caused by vibration or external force during equipment operation; this process does not require an additional power source, has a compact structure and rapid response, ensuring the repeatability of transmission positioning, and greatly improving the system's anti-interference ability and long-term operational stability through a pure mechanical self-locking mechanism. Through several adjustment structures, a pair of vertically meshing bevel gears reverses the rotational motion applied by the operator and converts it into a precise rotational drive of the threaded rod. Then, through the threaded pair, the rotational motion is linearly converted into the vertical lifting motion of the abutment block, thereby achieving precise and independent fine-tuning of the equipment's horizontal posture. After leveling, the unique pin-type locking mechanism can immediately lock the entire transmission chain, effectively preventing mechanism reversal or position drift caused by equipment vibration or unexpected interference. Thus, without the need for external power, a highly stable and highly disturbance-resistant working foundation is established for the heating chamber, fundamentally ensuring the geometric reference and operational stability required for the heat treatment process.

[0017] The following is combined with Figure 1-5This invention describes a specific embodiment of an aging furnace for high-efficiency heat preservation in the production of busbars. The furnace includes a heating chamber body 1, a supporting structure, and several adjusting structures. A shelf 32 and a heating head 33 are located inside the heating chamber body 1. A limiting structure is provided on the supporting structure. The supporting structure includes a fixing plate 2 mounted on the heating chamber body 1. A sleeve 3 is provided on the fixing plate 2, and a transmission rack 4 is movably mounted inside the sleeve 3. A connecting plate 5 is provided on the transmission rack 4, a guide rod 6 is provided on the connecting plate 5, a placement plate 7 is provided on the guide rod 6, and a first spring 31 is provided on the connecting plate 5. 31 is connected to the placement plate 7, and the placement plate 7 is movably equipped with casters 8. The fixed plate 2 is equipped with a drive assembly. The heating chamber is equipped with a furnace door (not shown in the figure). The fixed plate 2 is installed on the furnace door. When the furnace door needs to be supported, the transmission rack 4 moves in the sleeve 3. The transmission rack 4 can drive the connecting plate 5 to move. The connecting plate 5 can drive the casters 8 to move and abut against the placement plane. When the furnace door rotates, the casters 8 follow the furnace door. When the casters 8 encounter the protruding placement plane, the casters 8 can drive the guide rod 6 to move towards the connecting plate 5. The first spring 31 provides buffering to make the furnace door open and close smoothly. The shelf 32 can place metal items to make them stable during heat treatment. Several heating heads 33 are provided to make the metal items heat evenly during heating.

[0018] Advantageously, the guide rods 6 are provided in pairs. These guide rods 6, through precise parallelism control, work together on the placement plate 7, ensuring that it maintains a predetermined motion trajectory during lifting and lowering. This design significantly improves the rigidity of the system, effectively suppresses lateral overturning moments and radial sway, and provides a stable motion reference.

[0019] Advantageously, the drive assembly includes a placement frame 9 and a fixed frame 13. The placement frame 9 is mounted on the fixed plate 2, and a rotating shaft 10 is movably mounted on the placement frame 9. A rotating gear 11 is mounted on the rotating shaft 10 and meshes with the transmission rack 4. The fixed frame 13 is mounted on the fixed plate 2, and a movable rack 14 is movably mounted on the fixed frame 13. A rotating gear 12 is mounted at the end of the rotating shaft 10 away from the rotating gear 11 and meshes with the movable rack 14. Pulling the movable rack 14 allows it to move on the fixed frame 13. The movable rack 14 causes the rotating gear 12 to rotate, which in turn drives the rotating shaft 10 to rotate on the placement frame 9. The rotating shaft 10 drives the rotating gear 11 to rotate, and the rotating gear 11 drives the transmission rack 4 to move on the sleeve 3.

[0020] Advantageously, the movable rack 14 is provided with a pull block, which adopts an ergonomic design to provide the operator with a precise point of force application, ensuring that the pulling force acting on the movable rack 14 is always transmitted along its axis, thereby realizing smooth and jam-free linear displacement of the rack within the fixed frame 13, which greatly improves the accuracy of adjustment and operating efficiency. Advantageously, the limiting structure includes a limiting hole 20 and a fixing box 15. The limiting hole 20 is provided on the movable rack 14, and the fixing box 15 is mounted on the fixing frame 13. A sliding plate 16 is movably disposed inside the fixing box 15. A second spring 17 is provided on the sliding plate 16, and the end of the second spring 17 away from the sliding plate 16 abuts against the inner wall of the fixing box 15. A moving rod 18 is provided on the sliding plate 16, and a limiting rod 19 is provided on the side wall of the sliding plate 16 away from the moving rod 18, and the limiting rod 19 abuts against the limiting hole 20. When the moving rack 14 needs to be limited, the moving rack 14 pulls the moving rod 18 when it moves. The moving rod 18 can drive the sliding plate 16 to move within the fixed box 15. The sliding plate 16 can drive the limiting rod 19 to move away from the limiting hole 20. At this time, the second spring 17 is compressed. After the moving rack 14 moves to the predetermined position, the moving rod 18 is released, the second spring 17 returns to its original position, and the second spring 17 drives the sliding plate 16 to move within the fixed box 15. The sliding plate 16 can drive the limiting rod 19 to move into the limiting hole 20 on the moving rack 14, so as to fix and limit the moving rack 14.

[0021] Advantageously, the limiting holes 20 are provided in a plurality of manner, and the plurality of limiting holes 20 are equally spaced on the moving rack 14. The plurality of limiting holes 20 facilitate the use of the limiting rod 19 to fix and limit the moving rack 14 at different positions.

[0022] Advantageously, one of the plurality of adjustment structures includes a connecting frame 21 and a locking hole 28. The connecting frame 21 is mounted on the heating chamber body 1, and the locking hole 28 is provided on the connecting frame 21. A threaded rod 22 is movably mounted on the connecting frame 21, and an abutment block 23 is movably mounted on the threaded rod 22. A fixing rod 24 is provided on the connecting frame 21 and is movably connected to the abutment block 23. A rotating shaft 25 is movably mounted on the connecting frame 21, and a rotating bevel gear 26 is provided on the rotating shaft 25. A rotating plate 27 is provided on the rotating shaft 25, and a locking rod 29 is movably mounted on the rotating plate 27 and abuts against the locking hole 28. A rotating bevel gear 30 is provided at the end of the threaded rod 22 away from the abutment block 23. The bevel gear 30 meshes with the rotating bevel gear 26. Several locking holes 28 are provided and are circumferentially arranged on the connecting frame 21. Several adjustment structures are symmetrically arranged on the heating chamber body 1. When it is necessary to level the heating chamber body 1 to make it stable during operation, the locking rod 29 is removed from the rotating plate 27 and the rotating plate 27 is rotated. The rotating plate 27 can drive the rotating shaft 25 to rotate on the connecting frame 21. The rotating bevel gear 26 rotates under the action of the rotating shaft 25. The rotating bevel gear 30 drives the threaded rod 22 to rotate on the connecting frame 21 under the action of the rotating bevel gear 26. The abutment block 23 moves on the fixed rod 24 under the action of the threaded rod 22 until the abutment block 23 stops after abutting against the placement plane. Then, the locking rod 29 is inserted through the rotating plate 27 into the locking hole 28 to make the heating chamber body 1 stable during operation.

[0023] Advantageously, the rotating plate 27 is provided with anti-slip texture, and the operating surface of the rotating plate 27 is processed with regular anti-slip texture. These textures provide the operator with a firm grip by increasing the surface roughness, so that the applied rotational force can be efficiently and without loss transmitted to the rotating shaft 25, thereby ensuring the accuracy and efficiency of the adjustment action.

[0024] Working principle of this utility model: First, when the furnace door needs support, the moving rack 14 is pulled, allowing it to move on the fixed frame 13. The moving rack 14 causes the rotating gear 12 to rotate, which in turn drives the rotating shaft 10 to rotate on the placement frame 9. The rotating shaft 10 then drives the rotating gear 11 to rotate, which in turn drives the transmission rack 4 to move on the sleeve 3. The transmission rack 4 then drives the connecting plate 5 to move, and the connecting plate 5 drives the caster 8 to move and contact the placement surface. When the furnace door rotates, the caster 8 moves with the furnace door to distribute stress. When the caster 8 encounters a protruding placement surface, it drives the guide rod 6 to move towards the connecting plate 5. The first spring 31 provides cushioning, allowing the furnace door to open and close smoothly. When the moving rack 14 needs to be limited, it pulls the moving rod 18 during movement. The moving rod 18 drives the sliding plate 16 to move within the fixed box 15, and the sliding plate 16 drives the limiting rod 19 to move away from the limiting hole 20. When the second spring 17 is compressed, after the moving rack 14 moves to the predetermined position, the moving rod 18 is released, the second spring 17 returns to its original position, and the second spring 17 drives the sliding plate 16 to move within the fixed box 15. The sliding plate 16 can drive the limiting rod 19 to move into the limiting hole 20 on the moving rack 14, which can fix and limit the moving rack 14. When it is necessary to level the heating chamber body 1 to make it stable during operation, the locking rod 29 is removed from the rotating plate 27, and the rotating plate 27 is rotated. The rotating plate 27 can drive the rotating shaft 25 to rotate on the connecting frame 21. The rotating bevel gear 26 rotates under the action of the rotating shaft 25. The rotating bevel gear 30 drives the threaded rod 22 to rotate on the connecting frame 21 under the action of the rotating bevel gear 26. The abutment block 23 moves on the fixed rod 24 under the action of the threaded rod 22 until the abutment block 23 stops after abutting against the placement plane. Then the locking rod 29 is inserted through the rotating plate 27 into the locking hole 28 to make the heating chamber body 1 stable during operation.
