Description

Technical Field

[0001] This utility model relates to the field of annealing furnace technology, specifically to an annealing furnace that facilitates the loading and unloading of steel. Background Technology

[0002] Annealing furnaces are key equipment used for heat treatment of metallic materials. They are mainly used to eliminate internal stress, improve microstructure, and enhance plasticity and toughness through heating, holding, and slow cooling. They are widely used in metallurgy, machinery manufacturing, automotive, aerospace and other fields, and can process various metallic materials such as steel, aluminum alloys, and copper alloys. Annealing furnaces can be classified into electric heating, gas heating and oil heating types according to the heating method. Their structure usually includes a furnace body, heating system, temperature control system and cooling system. They are characterized by precise temperature control, flexible operation, energy saving and environmental protection, and are important industrial equipment for improving material performance.

[0003] Annealing furnaces designed for easy loading and unloading of steel are typically equipped with efficient loading and unloading systems, such as sliding furnace doors, track conveyors, or automated robotic arms, to ensure that steel can enter and exit the furnace quickly and smoothly.

They are compact in structure, easy to operate, and take into account both safety and energy efficiency, making them an indispensable and efficient piece of equipment in modern industry.

[0004] However, existing annealing furnaces that facilitate the loading and unloading of steel have traditional fixing methods that prevent the steel pipes from rotating evenly. This results in some parts being overheated while others are underheated during the heating process. Furthermore, the steel pipes may bend, deform, or even be damaged at high temperatures due to their own weight or uneven heating. In addition, traditional fixing and connection methods are difficult to adapt to steel of different specifications or shapes.

[0031] 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.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figure 1 , Figure 2 and Figure 4This utility model discloses an annealing furnace for easy loading and unloading of steel materials, comprising a processing platform 1, a bearing tank 2 on the top of the processing platform 1, which can support the required steel pipes and steel materials. A first servo motor 3 is fixedly connected to one side of the bearing tank 2, which allows a disc 4 to rotate inside the bearing tank 2. A handle 20 is provided on the other side of a pressure plate 19, which allows the pressure plate 19 to slide on a bearing plate 27. Bases 26 are fixedly connected to all four sides of the bottom of the processing platform 1, which allows the entire equipment to be placed in a designated position. A cylindrical heater 16 is provided on the inner wall of the bearing tank 2, which can heat the steel pipes and steel materials. Sealing rings 8 are provided on both sides of the outer ring of the disc 4, and the sealing rings 8 are rotatably connected to the bearing tank 2, which allows the side of the bearing tank 2 near the motor to remain sealed.

[0034] Reference Figure 2 and Figure 3 The output end of the first servo motor 3 passes through the bearing barrel 2 and is fixedly connected to the bearing block 5. A disc 4 is fixedly connected to one side of the bearing block 5. A uniformly distributed fixing frame 7 is fixedly connected to the outer ring of the disc 4, and the fixing frame 7 is rotatably connected to the bearing barrel 2. A second servo motor 6 is fixedly connected to one side of the disc 4. By rotating the bearing block 5, the fixing frame 7 rotates inside the bearing barrel 2, thereby driving the disc 4 to rotate inside the bearing barrel 2. This ensures that the steel pipe is heated evenly during the heating process, avoiding local overheating or underheating, and thus improving the annealing effect. The output end of the second servo motor 6 passes through the disc 4 and is fixedly connected to the first gear 9, and the first gear 9 is rotatably connected to the disc 4. A uniformly distributed second gear 10 is rotatably connected inside the disc 4, and the first gear 9 and the second gear 10 are meshed. A connecting rod 11 is fixedly connected to one end of both the first gear 9 and the second gear 10, and the connecting rod 11 is connected to the disc 4. The connecting rod 11 is rotatably connected to a connecting block 12 through one end of its outer wall. The connecting block 12 is fixedly connected to the disc 4. The inner wall of the connecting block 12 is provided with a rotating assembly, which includes a slider 13. The slider 13 is rotatably connected to the inner wall of the connecting block 12 and fixedly connected to one end of the connecting rod 11. One end of the slider 13 is provided with evenly distributed grooves 14. The inner wall of each groove 14 is slidably connected to a fixed rod 15, which is slidably connected to the connecting block 12. The rotation of the first gear 9 drives multiple second gears 10 to rotate, thereby causing the connecting rod 11 to rotate within the disc 4, which in turn causes the slider 13 to rotate within the connecting block 12. This allows the grooves 14 to drive the fixed rods 15, thus providing multi-point support for the inner wall of the steel pipe. This increases the stability of the steel pipe and prevents deformation caused by uneven heating or mechanical vibration during the heating process, thereby improving the processing accuracy of the steel pipe.

[0035] Reference Figure 4The bottom of the processing platform 1 is equipped with a feeding assembly, which includes a support plate 27. The support plate 27 is fixedly connected to one side of the bottom of the processing platform 1. A support rod 17 is fixedly connected through and to the top of the support plate 27. A first spring 18 is sleeved on one end of the outer ring of the support rod 17. A pressure plate 19 is fixedly connected to the other end of the first spring 18. The pressure plate 19 is slidably connected through and to the support rod 17. The pressure plate 19 is slidably connected to the support plate 27. By allowing the pressure plate 19 to slide on the support plate 27, it slides on the support rod 17, thereby compressing the first spring 18, so that the annealing furnace can... The quick opening reduces the time for loading and unloading steel. One side of the pressure plate 19 is fixedly connected to a uniformly distributed telescopic rod 21. The outer ring of each telescopic rod 21 is fitted with a second spring 22. One end of each telescopic rod 21 is fixedly connected to a support block 23, and the support block 23 is slidably connected to the bearing bucket 2. One side of the support block 23 is rotatably connected to a uniformly distributed limiting rod 24. One end of each limiting rod 24 is provided with a protective block 25. Through the telescopic deformation of the telescopic rod 21, the support block 23 can be squeezed against the second spring 22. Then, through the rotation of the limiting rod 24, the clamping device can be quickly adjusted to adapt to steel pipes of different lengths.

[0036] Working principle: By sliding the pressure plate 19 on the support plate 27, the pressure plate 19 slides on the support rod 17, thereby compressing the first spring 18, causing the support block 23 to slide out of the support barrel 2. Then, a specified number of steel pipes are placed at the connecting block 12. Subsequently, driven by the second servo motor 6, the first gear 9 rotates within the disc 4. The first gear 9 meshes with the second gear 10, causing multiple second gears 10 to rotate within the disc 4. This causes the connecting rod 11 to rotate simultaneously within the disc 4 and the connecting block 12, thereby causing the slider 13 to rotate within the connecting block 12, thus passing through the slide groove 14. The moving drive fixing rod 15 slides on the slider 13, thereby limiting and fixing the required steel pipe at multiple points. Then, the rebound of the first spring 18 resets the pressure plate 19, and then the protective block 25 contacts the other end of the steel pipe. Then, the deformation of the telescopic rod 21 compresses the second spring 22. Then, the rebound of the second spring 22 can be linked with the fixing rod 15 to clamp and fix steel pipes of different sizes. Then, the rotation of the fixing frame 7 in the bearing barrel 2 causes the disc 4 to rotate in the bearing barrel 2. At the same time, the rotation of the limiting rod 24 and the support block 23 causes the steel pipe to rotate in the bearing barrel 2.
