[0001] The invention relates to the technical field of nickel-based alloy bars, and in particular to a nickel-based alloy bar heat treatment device and a heat treatment method thereof. Background Art

[0002] Nickel-based alloy is a high-temperature corrosion-resistant alloy with good corrosion resistance, heat resistance and fatigue resistance. During the production and processing of nickel-based alloy, it is necessary to use corresponding heat treatment equipment to perform heat treatment. For example, during annealing, an annealing furnace is required.

[0003] Prior art includes a Chinese patent with authorization announcement number: CN219409864U. This invention patent relates to the field of metal processing technology, and in particular to a nickel alloy bar processing heat treatment device. The heat treatment equipment in the prior art cannot turn the material over, which easily leads to uneven heating, and directly affects the effect of the heat treatment. In order to solve the above problems, the present invention provides a nickel alloy bar processing heat treatment device, including a furnace body, a conveying assembly and a flipping assembly. The conveying assembly includes four roller brackets and a plurality of roller motors. The flipping assembly includes a flipping bracket, a flip turntable and a flipping motor. The conveying assembly is installed in the furnace body, and the flipping assembly is arranged between two adjacent roller brackets. The four roller brackets are fixedly installed at the bottom of the furnace body. The present invention solves the problem that the heat treatment equipment in the prior art cannot turn the material over, which easily leads to uneven heating and affects the heat treatment, thereby realizing all-round heat treatment of the material and improving the quality of the heat treatment.

[0004] When a conventional annealing furnace performs annealing heat treatment on nickel-chromium alloy bars, a number of nickel-chromium alloy bars are first placed on a placement tray, and then the placement tray is pushed into the annealing furnace, the furnace door is closed, and the controller is operated to adjust the settings of the annealing furnace, and then the nickel-chromium alloy bars are heat treated. However, in the actual processing process, it is found that the surface of the nickel-chromium alloy bars is relatively smooth, so when placed on the placement tray, rolling deviation will occur, and they will contact each other, which will affect the heating effect of the nickel-chromium alloy bars in the annealing furnace, and then affect the annealing effect, reducing the use effect and work efficiency of the annealing furnace. Summary of the invention

[0005] The present invention aims to solve the problem that the surface of the nickel-chromium alloy rod is relatively smooth, so when placed on a placing plate, rolling deviation will occur, and they will contact each other, which will affect the heating effect of the nickel-chromium alloy rod in the annealing furnace, thereby affecting the annealing effect and reducing the use effect and work efficiency of the annealing furnace. A nickel-based alloy rod heat treatment device and a heat treatment method are proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a nickel-based alloy bar heat treatment device and a heat treatment method thereof, comprising an annealing furnace, a furnace door is hinged on the surface of the annealing furnace, a controller is fixedly connected to the surface of one side of the annealing furnace, a plurality of placement plates are slidably provided on the inner wall of the annealing furnace, and a stabilizing device is respectively provided on the surfaces of the plurality of placement plates, the stabilizing device comprises two placement plates, the two placement plates are respectively fixedly connected to the surfaces of the placement disks, a plurality of the placement disks are respectively fixedly connected to the surfaces of the fixing frames, a connecting plate is rotatably connected to the surface of the fixing frames, a pressure plate is fixedly connected to the surface of the connecting plates, and the surface of the fixing frames A screw is threadedly connected through it, and a mounting rod is fixedly connected to the surface of the pressure plate, and both side surfaces of the mounting rod are fixedly connected to a connecting shaft, and the rotation on the arc surface of the connecting shaft is connected to a rotating plate, and one side surface of the rotating plate is fixedly connected to a reinforcing frame, and the end of the mounting rod away from the pressure plate is fixedly connected to a sliding rod, and the surface of the sliding rod is slidably connected to a positioning plate, and the cross-section of the positioning plate is "U"-shaped, and one end of the positioning plate is fixedly connected to a stopper, and a positioning groove is provided on one side surface of the rotating plate, and the positioning plate is clamped with the inner wall of the positioning groove, and a spring is fixedly connected to the surface of the rotating plate, and the other end of the spring is fixedly connected to the inner wall of the positioning plate.

[0007] The effect achieved by the above components is: when the annealing furnace is used to perform heat treatment annealing processing on the nickel-chromium alloy rods, firstly, a plurality of rods are placed in the grooves on the surfaces of the two placement plates on the placement disk respectively. After they are arranged neatly, the connecting plate is rotated to make the connecting plate rotate on the arc surface of the fixing frame until the pressure plate fixedly connected at one end of the connecting plate contacts and presses on the arc surface of the rods. Then, the screw on the fixing frame is rotated until one end of the screw contacts and presses on the surface of the pressure plate to stabilize the position of the pressure plate. Then, the rotating plates on both sides of the mounting rod are rotated to make the rotating plates rotate on the arc surface of the connecting shaft fixedly connected to the mounting rod until the reinforcing frame fixedly connected at one end of the rotating plate is clamped on the surface of the nickel-chromium alloy rods. Because the positioning plate and the rotating plate are fixedly connected, the reinforcing frame is clamped on the surface of the nickel-chromium alloy rods. The plates are connected by springs, so during the rotation of the rotating plate, the positioning plate will be on the surface of the slide rod, and then when the position of the reinforcing frame is stable, the positioning plate will be snapped into the positioning groove on the surface of the rotating plate, and finally the placement plate will be pushed into the annealing furnace, and the furnace door will be closed. The controller will be operated to adjust the settings of the annealing furnace, and then the nickel-chromium alloy bars will be heat-treated. At this time, when the annealing furnace is used to perform heat treatment on the nickel-chromium alloy bars, several bars can be placed more stably and neatly on the placement plate, and abnormal shaking and deviation are not likely to occur, which will cause contact between the bars, resulting in affecting the heating effect on the surface of the bars, thereby improving the use effect and work efficiency of the annealing furnace and improving the processing effect on the nickel-chromium alloy bars.

[0008] Preferably, a fixing ring is fixedly connected to the surface of the connecting plate, and the screw rod is plugged into the inner wall of the fixing ring.

[0009] The effect achieved by the above components is: through the setting of the fixing ring, when the screw contacts and is extruded on the surface of the pressure plate, it is not easy to slide and dislocate abnormally, which can better ensure the stability of the position of the pressure plate, and thus better limit and fix the rods on the plate.

[0010] Preferably, one end of the screw rod is fixedly connected to an operating block, and a surface of the operating block is provided with a plurality of anti-slip protrusions.

[0011] The effects achieved by the above components are: through the setting of the operating block, the screw can be rotated more conveniently when in use, so that the nickel-chromium alloy rod can be operated more conveniently before and after annealing.

[0012] Preferably, a nut is threadedly connected on the arc surface of the screw rod, and the nut abuts against a side surface of the fixing frame.

[0013] The effect achieved by the above components is that, through the setting of the nut, when the screw limits the position of the connecting plate, the screw is not easy to rotate loose, thereby ensuring the limiting effect on the rod.

[0014] Preferably, stabilizing grooves are respectively formed on both side surfaces of the pressure plate, and stabilizing rods are clamped on the inner walls of the stabilizing grooves, and the stabilizing rods are fixedly connected to the surface of the placement plate.

[0015] The effect achieved by the above components is that through the clamping arrangement of the stabilizing rod and the stabilizing groove, the position stability of the pressing plate can be better ensured when the pressing plate limits the rods on the placement plate.

[0016] Preferably, a protective device is provided on the surface of the controller, and the protective device includes a rotating shaft, which is fixedly connected to the surface of the controller, a mounting block is rotatably connected to the arc surface of the rotating shaft, and a baffle is fixedly connected to one side surface of the mounting block.

[0017] The effect achieved by the above components is that when the annealing furnace is in daily use, the buttons and other components of the controller are not easily contacted and collided by other objects, which may cause abnormal operation of the annealing furnace.

[0018] Preferably, a fixing frame is fixedly connected to one side surface of the baffle, a fixing block is fixedly connected to one side surface of the controller, and the fixing frame is snap-connected to the fixing block.

[0019] The effect achieved by the above components is: through the clamping setting of the fixing block and the fixing frame, the baffle can be more stably shielded on the surface of the controller, and it is not easy to shake or shift the position, thereby better protecting the buttons and other components on the controller.

[0020] Preferably, reinforcement pads are fixedly connected to both sides of the surface of the fixing block, and the reinforcement pads are rubber pads.

[0021] The effect achieved by the above components is: through the provision of the reinforcement pad, the friction force between the fixing frame and the fixing block during the clamping is further increased, thereby further improving the limiting effect of the baffle.

[0022] A nickel-based alloy bar heat treatment method and a nickel-based alloy bar heat treatment device are used.

[0023] In summary, the beneficial effects of the present invention are: When using an annealing furnace to perform heat treatment on nickel-chromium alloy bars, several bars can be placed on the placement plate more stably and neatly, and are less likely to shake or deviate abnormally, causing contact between the bars, resulting in uneven heating effects on the surface of the bars, thereby improving the use effect and work efficiency of the annealing furnace and improving the processing effect of the nickel-chromium alloy bars.

A spring 518 is fixedly connected to the surface of the rotating plate 513, and the other end of the spring 518 is fixedly connected to the inner wall of the positioning plate 519. When the annealing furnace 1 is used to perform heat treatment annealing of nickel-chromium alloy bars, first, a plurality of bars are placed in the grooves on the surfaces of the two placement plates 51 on the placement tray 2 respectively. After they are arranged neatly, the connecting plate 53 is rotated to connect them. The plate 53 rotates on the arc surface of the fixed frame 52 until the pressure plate 54 fixedly connected to one end of the connecting plate 53 contacts and presses on the arc surface of the rod, and then the screw 55 on the fixed frame 52 is rotated until one end of the screw 55 contacts and presses on the surface of the pressure plate 54 to stabilize the position of the pressure plate 54, and then the rotating plates 513 on both sides of the mounting rod 511 are rotated to rotate on the arc surface of the connecting shaft 512 fixedly connected to the mounting rod 511 on the rotating plate until the reinforcing frame 514 fixedly connected to one end of the rotating plate 513 is clamped on the surface of the nickel-chromium alloy rod.

Through the setting of the operating block 58, the screw 55 can be rotated more conveniently when in use, so that the nickel-chromium alloy rod can be operated more conveniently before and after annealing.

Through the setting of the nut 57, when the screw rod 55 limits the position of the connecting plate 53, the screw rod 55 is not easy to rotate loose, thereby ensuring the limiting effect of the rod material. Stabilizing grooves 59 are respectively provided on the two side surfaces of the pressure plate 54, and the inner wall of the stabilizing groove 59 is clamped with a stabilizing rod 510. The stabilizing rod 510 is fixedly connected to the surface of the placement plate 2. Through the clamping setting of the stabilizing rod 510 and the stabilizing groove 59, the position stability of the pressure plate 54 can be better ensured when limiting the rod material on the placement plate 51.

[0032] Reference Figure 1 and Figure 7 As shown, this embodiment discloses that a protective device 6 is provided on the surface of the controller 4, and the protective device 6 includes a rotating shaft 61, and the rotating shaft 61 is fixedly connected to the surface of the controller 4. A mounting block 62 is rotatably connected to the circular arc surface of the rotating shaft 61, and a baffle 63 is fixedly connected to the surface of one side of the mounting block 62. When the controller 4 completes the setting and debugging of the annealing furnace 1, the baffle 63 is rotated to make the mounting block 62 fixedly connected to the baffle 63 rotate on the circular arc surface of the rotating shaft 61 on one side of the surface of the controller 4 until the baffle 63 covers the surface of the controller 4. At this time, when the annealing furnace 1 is in daily use, the buttons and other components of the controller 4 are not easily contacted and collided by other objects, resulting in abnormal operation of the annealing furnace 1.

[0033] Reference Figure 1 and Figure 7As shown, the present embodiment discloses that a fixed frame 64 is fixedly connected to a surface of one side of the baffle 63, a fixed block 65 is fixedly connected to a surface of one side of the controller 4, the fixed frame 64 is clipped with the fixed block 65, and the clipping setting of the fixed block 65 and the fixed frame 64 allows the baffle 63 to be more stably shielded on the surface of the controller 4, and is not prone to position shaking or displacement, thereby better protecting the buttons and other components on the controller 4, and reinforcement pads 66 are fixedly connected to both sides of the surface of the fixed block 65, respectively, and the reinforcement pads 66 are rubber pads, and the setting of the reinforcement pads 66 further increases the friction between the fixed frame 64 and the fixed block 65 when clipped, thereby further improving the limiting effect of the baffle 63.

[0034] Working principle: When the annealing furnace 1 is used to perform heat treatment annealing of nickel-chromium alloy bars, first, a number of bars are placed in the grooves on the surfaces of the two placement plates 51 on the placement tray 2. After they are arranged neatly, the connecting plate 53 is rotated to make the connecting plate 53 rotate on the arc surface of the fixing frame 52 until the pressing plate 54 fixedly connected to one end of the connecting plate 53 contacts and squeezes on the arc surface of the bars. Then, the operating block 58 fixedly connected to the screw rod 55 is rotated to make the screw rod 55 on the fixing frame 52 rotate until one end of the screw rod 55 is inserted into the fixing ring 56 on the surface of the pressing plate 54 to stabilize the position of the pressing plate 54. Then, the rotating plates 513 on both sides of the mounting rod 511 are rotated to make the rotating plates rotate on the arc surface of the connecting shaft 512 fixedly connected to the mounting rod 511 until the reinforcing frame 514 fixedly connected to one end of the rotating plate 513 is clamped on the nickel-chromium alloy bars. Surface, because the positioning plate 519 is connected to the rotating plate 513 by a spring 518, during the rotation of the rotating plate 513, the positioning plate 519 will be on the surface of the slide bar 516, and then when the position of the reinforcing frame 514 is stable, the positioning plate 519 will be clamped in the positioning groove 515 on the surface of the rotating plate 513, and finally the placement tray 2 is pushed into the annealing furnace 1, and the furnace door 3 is closed, and the controller 4 is operated to adjust the settings of the annealing furnace 1, and then the nickel-chromium alloy rods are heat-treated. At this time, when the annealing furnace 1 is used to perform heat treatment on the nickel-chromium alloy rods, several rods can be placed more stably and neatly on the placement tray 2, and it is not easy to have abnormal shaking and deviation, and cause contact between the rods, which affects the heating effect on the surface of the rods, thereby improving the use effect and work efficiency of the annealing furnace 1, and improving the processing effect of the nickel-chromium alloy rods.

[0035] After the controller 4 completes the setting and debugging of the annealing furnace 1, the baffle 63 is rotated to make the mounting block 62 fixedly connected to the baffle 63 rotate on the arc surface of the rotating shaft 61 on one side of the surface of the controller 4 until the baffle 63 covers the surface of the controller 4, so that the fixing frame 64 fixedly connected to the baffle 63 is clamped on the fixing block 65 on the surface of the controller 4. At this time, when the annealing furnace 1 is used in daily life, the buttons and other components of the controller 4 are not easily contacted and collided by other objects, resulting in abnormal operation of the annealing furnace 1.
