Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable equipment, and more specifically to a heat treatment device for a high-strength and toughness alloy bushing. Background Art
[0002] Existing heat treatment devices for alloy bushings often only heat the bushing's exterior surface during the heating process, ignoring the temperature distribution within the bushing. Because bushings are typically hollow, traditional heating methods cannot simultaneously maintain uniform temperature inside and outside the bushing. This results in a large temperature difference between the inside and outside of the bushing during heating, easily leading to uneven heating. This uneven heating can lead to uneven stress distribution in the material, which in turn affects the bushing's mechanical properties, such as toughness and strength, and can even cause cracking or deformation during the subsequent cooling process.
[0003] Therefore, the existing technology has great limitations in uniformly heating the alloy bushing. There is an urgent need for a device that can heat the inside and outside of the bushing simultaneously to improve heating uniformity, reduce temperature differences, and ensure the structural stability of the bushing during high-temperature heat treatment. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a high-strength and toughness alloy bushing heat treatment device to solve the problem that the existing alloy bushing heat treatment device in the above-mentioned background technology can only heat the outer surface of the bushing during the heating process, while ignoring the temperature distribution inside the bushing.
[0005] The utility model provides the following technical solutions: a high-strength and toughness alloy bushing heat treatment device, comprising a heating furnace bottom plate, a heating furnace main body fixedly installed on the top of the heating furnace bottom plate, a motor arranged inside the heating furnace bottom plate, the top of the motor extends to the interior of the heating furnace main body, a limit plate fixedly installed on the top of the motor, a bushing to be heated is arranged on the limit plate, two limit knobs are arranged on the limit plate, a bushing slot is fixedly installed on the top of the heating furnace main body, a top cover is sealed on the top of the bushing slot, an internal infrared heating rod is fixedly installed on the bottom end of the top cover, the internal infrared heating rod is located inside the bushing to be heated, two internal and external infrared heating rods are fixedly installed inside the heating furnace main body, the internal and external infrared heating rods are both located outside the bushing to be heated, and a control panel is arranged on one side of the top of the heating furnace bottom plate. When in use, open the top cover at the top of the bushing slot, and then insert the bushing to be heated vertically into the heating furnace body from the bushing slot. At this time, the bottom end of the bushing to be heated is in contact with the limit plate. The user opens the sealed door in front of the heating furnace body to limit the bushing, and then installs the top cover together with the internal infrared heating rod back to the top of the bushing slot. At this time, the internal infrared heating rod will be inserted into the inside of the bushing. When the internal infrared heating rod and the internal and external infrared heating rods are started, the inside and outside of the bushing will be heated together. At the same time, the limit plate drives the bushing to rotate, further making the bushing heated evenly. In actual use, it effectively solves the problem that the existing alloy bushing heat treatment device can only heat the outer surface of the bushing during the heating process, but ignores the temperature distribution inside the bushing.
[0006] Furthermore, a rotating support shaft is fixedly mounted within the heating furnace body, the sleeve to be heated is located within the rotating support shaft, and the bottom ends of the internal and external infrared heating rods both extend below the rotating support shaft. By fixing the rotating support shaft within the heating furnace body and positioning the sleeve to be heated within the rotating support shaft, the sleeve is ensured to maintain stable rotation during the heating process.
[0007] Furthermore, a flue gas inlet pipe is fixedly mounted on one side of the heating furnace body, and a flue gas heat recovery box is sheathed on the outer surface of the flue gas inlet pipe. Low-temperature water is provided inside the flue gas heat recovery box. By fixing the flue gas inlet pipe on one side of the heating furnace body, sheathing the flue gas heat recovery box on the outer surface of the flue gas inlet pipe, and providing low-temperature water inside, effective cooling and temperature reduction of the flue gas is achieved. The circulation of low-temperature water effectively recovers waste heat, while reducing the exhaust temperature, thereby improving the energy efficiency and environmental friendliness of the equipment.
[0008] Furthermore, a bushing insert is fixedly mounted on the top of the limit plate. The bushing insert is truncated cone-shaped, and the top of the bushing insert is located at the bottom end of the inner portion of the bushing to be heated. By fixing the bushing insert on the top of the limit plate and designing it as a truncated cone structure, the force on the inner bottom end of the bushing is more stable. The truncated cone shape of the bushing insert allows the inner portion of the bushing and the bushing insert to be more securely mounted.
[0009] Furthermore, a high-density ceramic fiber insulation jacket is fixedly mounted on the outer surface of the heating furnace body. This effectively isolates the heat from the outside world, improving the equipment's thermal insulation performance while reducing energy loss, further enhancing heat treatment efficiency and equipment safety.
[0010] Furthermore, a high-temperature resistant lining made of alumina ceramic is fixedly installed inside the main body of the heating furnace. By fixing the high-temperature resistant lining made of alumina ceramic inside the main body of the heating furnace, the high-temperature resistance of the heating zone is improved and the durability of the equipment is enhanced.
[0011] The technical effects and advantages of this utility model are:
[0012] 1. This utility model, by providing a heating furnace body, a limit plate, a bushing slot, an internal infrared heating rod, and internal and external infrared heating rods, effectively solves the problem that existing alloy bushing heat treatment devices often only heat the outer surface of the bushing during the heating process, while ignoring the temperature distribution inside the bushing.
[0013] 2. The utility model fixes a rotating support shaft inside the heating furnace body and places the liner to be heated inside the rotating support shaft, thereby ensuring that the liner maintains stable rotation during the heating process. BRIEF DESCRIPTION OF THE DRAWINGS
