[0002] Nickel-based alloys are a class of alloys that have high strength and certain resistance to oxidation and corrosion at high temperatures of 650–1000℃. High-temperature alloys can be classified according to their matrix as: iron-based high-temperature alloys, nickel-based high-temperature alloys, and cobalt-based high-temperature alloys. Nickel-based high-temperature alloys are simply referred to as nickel-based alloys.
[0003] When workers perform heat treatment on nickel-based alloy bars, they undergo a solution treatment process. This process involves heating the nickel-based alloy bars to a specified temperature and then quenching them at high temperatures. The process first involves removing the quenched nickel-based alloy bars from the quenching furnace and then hoisting them to a cooling tank for cooling. However, the stability of the nickel-based alloy bars is difficult to guarantee during hoisting, as they are prone to swaying in the air and posing a safety hazard to the workers. Therefore, a heat treatment device for nickel-based alloy bars is proposed. Utility Model Content

[0025] 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.
[0026] Please see Figure 1-6As shown, a heat treatment device for nickel-based alloy bars includes a quenching furnace body 1 and a conveyor body 2 disposed on its right side. A cooling tank 3 is disposed on the right side of the conveyor body 2. Smooth rods 7 are welded to the front and rear sides of the top of the cooling tank 3. A movable plate 8 is fixedly connected to the top of the right side of a U-shaped frame 442. The interior of the movable plate 8 is slidably connected to the surface of the smooth rods 7. This arrangement can prevent the U-shaped frame 442 from shaking or shifting during movement, thereby ensuring the stability and accuracy of the entire movable structure 4. The interior of the cooling tank 3 is provided with a movable structure 4 for driving the quenched nickel-based alloy bars to cool down. The movable structure 4 includes a sliding connection to the surface of the smooth rods 7. The cooling tank 3 has a movable frame 41 inside, with a first slider 42 fixedly connected to both the front and rear sides of the movable frame 41. The cooling tank 3 has a first sliding groove 43 opened at both the front and rear sides of the inner cavity. The first slider 42 is slidably connected to the inner cavity of the first sliding groove 43. The bottom of the movable frame 41 is respectively provided with a guide mechanism 44 and a transmission mechanism 45. The transmission mechanism 45 includes a support plate 451 fixedly connected to the right side of the cooling tank 3. A motor 452 is bolted to the top of the support plate 451. The output shaft of the motor 452 is fixedly connected to a screw 453. The surface of the screw 453 is threadedly connected to the inner cavity of the bottom of the U-shaped frame 442. One end of the screw 453 is threadedly connected to the inner cavity of the cooling tank 3.
[0027] With the transmission mechanism 45 in place, when the operator turns on the motor 452, the motor 452 drives the screw 453 to rotate. The screw 453 drives the U-shaped frame 442 to move, which in turn drives the movable frame 41 connected to the U-shaped frame 442 to move inside the cooling tank 3. This allows the nickel-based alloy rod to move while being cooled. During this process, the water flow moves relative to the rod, allowing for better contact with the nickel-based alloy rod, thereby improving the cooling effect. The guide mechanism 44 includes second sliders 441 fixedly connected to the left and right sides of the bottom of the movable frame 41. A U-shaped frame 442 is slidably connected to the bottom of the cooling bath 3. Second sliding grooves 443 are provided on both the left and right sides of the U-shaped frame 442. A second slider 441 is slidably connected to the second sliding grooves 443. Through the guide mechanism 44, the second slider 441 is slidably connected to the second sliding grooves 443 on the U-shaped frame 442, enabling it to move with the movable frame 41 inside the cooling bath 3. When the U-shaped frame 442 moves laterally, the second slider 441 is forced to move the movable frame 41 laterally. During this process, the first slider 42 cooperates with the first sliding groove 43 to move the movable frame 41 longitudinally. The position is adjusted. Through the setting of the moving structure 4, after the quenched nickel-based alloy bar is moved to the top of the moving frame 41 by the conveyor body 2, the moving frame 41 carries the nickel-based alloy bar and, through the cooperation of the first slider 42 and the first slide groove 43, can drive the quenched nickel-based alloy bar to move inside the cooling tank 3. The cooperation of the first slider 42 and the first slide groove 43 can guide the moving frame 41 to slide in a specific direction, thereby ensuring the stability and accuracy of the movement. The surface of the moving structure 4 is provided with a shielding structure to prevent the nickel-based alloy bar from falling. 5 and limiting structure 6, shielding structure 5 includes a third slide groove 51 opened on the front and rear of the left side of the movable frame 41, a fixed column 52 is fixedly connected inside the third slide groove 51, a third slider 54 is slidably connected to the surface of the fixed column 52, a shielding plate 55 is fixedly connected to one side of the third slider 54, a shielding assembly 56 is provided at the bottom of the shielding plate 55, the shielding assembly 56 includes a connecting plate 561 fixedly connected to the bottom of the shielding plate 55, a fixed plate 562 is fixedly connected to the left side of the inner cavity of the cooling groove 3, and the top of the connecting plate 561 is in contact with the bottom of the fixed plate 562.
[0028] With the shielding component 56, the connecting plate 561 and the fixed plate 562 cooperate with each other. When the moving frame 41 is raised, the fixed plate 562 limits the raising of the connecting plate 561, thereby releasing the cooperation between the third slider 54 and the magnet 53. This allows control of the position of the shielding plate 55, so that the nickel-based alloy rod can move onto the moving frame 41 along with the conveyor body 2. A magnet 53 is installed at the top of the third slide 51. The shielding structure 5 prevents the nickel-based alloy rod from falling off the left side of the moving frame 41 during its movement inside the cooling tank 3. When the moving frame 41 moves downwards, the magnet 53 in the third slide 51 descends and cooperates with the third slider 54. The third slider 54 is made of iron, thus the position of the shielding plate 55 can be limited by the cooperation between the third slider 54 and the magnet 53. When the movable frame 41 moves laterally, the baffle plate 55 can move with the movable frame 41 to block and limit the nickel-based alloy rod in the movable frame 41, preventing water flow from affecting the stability of the nickel-based alloy rod placed in the movable frame 41. The limiting structure 6 includes a flap 61 hinged to the right side of the movable frame 41. Limiting plates 62 are fixedly connected to the front and rear of the surface of the flap 61. Limiting pins 63 are rotatably connected to the front and rear of the right side of the movable frame 41. The limiting pins 63 cooperate with the limiting plates 62. With the setting of the limiting structure 6, the flap 61 rotates around the hinge point. When the flap 61 rotates to the appropriate position, the limiting pins 63 are rotated to fix the limiting plates 62, thereby fixing the position of the flap 61 and limiting the nickel-based alloy rod, restricting the position of the nickel-based alloy rod on the right side of the movable frame 41, thereby preventing it from falling to the right.
[0029] It is worth noting that the technical features proposed in this technical solution, such as the quenching furnace body 1 and the conveyor body 2, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.
[0030] Working principle: After the nickel-based alloy bar is placed on the support plate 451, the support plate 451 can be moved by the conveyor body 2 to move the nickel-based alloy bar placed on the support plate 451 into the quenching furnace body 1. The bar is heated to the predetermined quenching temperature by the heating element in the furnace and held at that temperature for a period of time to homogenize the internal structure. After heating is completed, the conveyor body 2 is started and conveys the high-temperature bar to the right side of the quenching furnace and to the top of the moving frame 41. At this time, the moving frame 41 is located on the left side of the cooling tank 3. Then, the motor 452 is started to drive the screw 453 to rotate and drive the U-shaped frame 442 to move to the right. At this time, the moving frame 41 moves laterally in the cooling tank 3 through the cooperation of the first slider 42 and the first slide groove 43. During this process, the second slider 441 and the second slide groove 443 cooperate to drive the moving frame 41 to move longitudinally. When the moving frame 41 moves downward, the magnet 53 in the third slide groove 51 descends and moves with the third slider 54. In conjunction with this, the third slider 54 is made of iron, which allows the position of the baffle 55 to be restricted through the cooperation of the third slider 54 and the magnet 53. When the moving frame 41 moves laterally, the baffle 55 can move with the moving frame 41 to block and limit the nickel-based alloy rod in the moving frame 41, thereby preventing the water flow from affecting the stability of the nickel-based alloy rod placed in the moving frame 41. At this time, the nickel-based alloy rod is completely immersed in the coolant of the cooling tank 3, so that the nickel-based alloy rod is in contact with the inside of the cooling tank 3. The coolant is fully in contact with the material. When the moving frame 41 moves, the second slider 441 slides in the second groove 443 of the U-shaped frame 442. The smooth rod 7 cooperates with the moving plate 8 to prevent the U-shaped frame 442 and the moving frame 41 from deviating and to ensure a stable moving trajectory. When the nickel-based alloy bar is cooled to the target temperature, the moving frame 41 stops on the right side of the cooling tank 3. Then, the limit pin 63 is rotated and the flip plate 61 is flipped. After that, the cooled nickel-based alloy bar is taken out from the moving frame 41 and can proceed to the next process.
