Description

Technical Field

[0001] This invention belongs to the field of nickel-based alloy annealing and straightening technology, and specifically relates to an online annealing and straightening device for nickel-based alloys. Background Technology

[0002] Nickel-based alloys are superalloy systems formed by adding elements such as chromium, molybdenum, tungsten, and niobium to nickel (≥50%) as the base. They possess excellent high-temperature strength, oxidation resistance, and corrosion resistance. Due to their excellent properties such as high-temperature strength, oxidation resistance, and corrosion resistance, nickel-based alloys are widely used in aerospace, energy, chemical and other fields.

[0003] In the production of nickel-based alloys, online annealing is one of the important processing steps. Heating and cooling the nickel-based alloys can eliminate internal stress, improve their microstructure and mechanical properties. However, during the annealing process, due to the inherent characteristics of nickel-based alloy materials and factors such as uneven heating and cooling, deformation problems such as bending and twisting may occur, which seriously affect the quality of the product and subsequent processing. Therefore, after online annealing of nickel-based alloys, straightening treatment needs to be performed in a timely manner.

[0004] However, existing annealing straightening devices are not stable enough in clamping nickel-based alloys and cannot adapt to the annealing straightening of nickel-based alloys of different sizes. This can easily lead to material slippage during the straightening process, affecting the straightening effect and even causing damage to the material surface. Furthermore, the existing straightening devices are not tightly integrated with the online annealing process, making it difficult to achieve continuous production of nickel-based alloy annealing straightening and resulting in low production efficiency. Therefore, there is an urgent need for an online annealing straightening device for nickel-based alloys to solve the above problems. Summary of the Invention

[0005] In view of the problems mentioned in the background art above, the purpose of this invention is to provide an online annealing and straightening device for nickel-based alloys.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] An online annealing and straightening device for nickel-based alloys includes a worktable, an annealing mechanism installed on one side of the top of the worktable, an assembly frame installed on the top of the worktable, a straightening mechanism installed on the assembly frame, a clamping and conveying mechanism installed between the straightening mechanism and the annealing mechanism on the assembly frame, and a cooling mechanism installed at the output end of the straightening mechanism on the worktable.

[0008] The annealing mechanism includes a heating chamber, on the upper and lower sides of which resistance heating devices are installed. The heating chamber has an inlet on the left side and an outlet on the right side. The clamping and conveying mechanism is installed outside the outlet, and a preheating component is installed outside the outlet of the heating chamber.

[0009] The clamping and conveying mechanism includes a high-temperature resistant conveying roller and a high-temperature resistant clamping roller. The high-temperature resistant conveying roller is fixedly installed on the workbench. An assembly plate is installed on the top of the high-temperature resistant clamping roller. T-shaped slide rods are installed on both sides of the top of the assembly plate. The T-shaped slide rods are slidably installed on the assembly frame. Spring bases are also installed on both sides of the top of the assembly plate. Springs are installed inside the spring bases. Spring top seats are installed on the free ends of the tops of the springs. The spring top seats are locked onto the assembly frame.

[0010] Further specifying, the preheating assembly includes a preheating box with an inlet on the left side and an outlet on the right side. The outlet is connected to the inlet. A preheating sleeve is installed between the inlet and outlet. The preheating sleeve has several evenly arranged air outlets, all of which are inclined from left to right and from top to bottom. Fans are installed on the upper and lower sides of the outlet, between the inner wall of the preheating box and the outer surface of the preheating sleeve. The inlet of the fan is connected to a suction pipe, and the other side of the suction pipe is connected to the inner side of the heating box. This structural design allows for preliminary preheating of nickel-based alloys to facilitate subsequent annealing.

[0011] Further specifying, the straightening mechanism includes a plurality of first straightening components, which are evenly arranged on an assembly frame. The spacing between two adjacent first straightening components is equal, and a second straightening component is provided between two adjacent first straightening components. Two sets of the second straightening components are mounted on a worktable. This structural design improves the straightening performance of nickel-based alloys.

[0012] Further specifying, the first straightening assembly includes a fixed roller seat and a movable roller seat. The fixed roller seat is fixedly mounted on the worktable, and a lower straightening roller is installed inside the fixed roller seat. An upper straightening roller is installed inside the movable roller seat, positioned directly above the lower straightening roller. A lifting plate is installed on the top of the movable roller seat. A hydraulic cylinder is installed at the corresponding position on the lifting plate of the assembly frame. A locking seat is installed at the power output end of the hydraulic cylinder, and the locking seat is installed on the lifting plate. This structural design facilitates the vertical positioning and straightening of nickel-based alloys.

[0013] Furthermore, guide rods are installed on both sides of the lifting plate, and guide holes are provided at the corresponding guide rods of the assembly frame. The guide rods are slidably installed in the guide holes, and threaded posts are installed on the top of the guide rods. Limit blocks are locked onto the guide rods through the threaded posts. This structural design enables the lifting plate to move vertically.

[0014] Further specifying, the second straightening assembly includes adjusting seats slidably mounted on both sides of the worktable, roller seats mounted on the inner sides of the adjusting seats, and straightening rollers mounted inside the roller seats. A transmission assembly is installed between the two sets of the second straightening assemblies, and one set of the second straightening assemblies is connected to a drive assembly. This structural design facilitates the left-right positioning and straightening of nickel-based alloys.

[0015] Furthermore, the worktable has a sliding groove at the corresponding adjustment seat, and a bidirectional threaded screw is installed in the sliding groove. Bearing seats are installed on both sides of the bidirectional threaded screw, and the bearing seats are installed in the sliding groove. Nut movable seats are installed on both sides of the bidirectional threaded screw, and the nut movable seats are installed at the bottom of the adjustment seat. This structural design facilitates the movement of the adjustment seat.

[0016] Furthermore, the nut movable seat is provided with guide blocks on both sides, and the slide groove is provided with guide grooves at the corresponding guide blocks. This structural design provides a smooth guiding effect for the nut movable seat.

[0017] Further specifying, the drive assembly includes a drive motor mounted on the bottom of the worktable, a drive wheel connected to the power output end of the drive motor, a drive belt connected to the drive wheel, a drive pulley connected to the other side of the drive belt, and a drive pulley connected to one side of a bidirectional threaded screw. The transmission assembly includes transmission pulleys mounted on the other side of the two sets of bidirectional threaded screws, and a transmission belt installed between the two sets of transmission pulleys. This structural design facilitates the synchronous movement of the two sets of drive assemblies.

[0018] Further specifying, the cooling mechanism includes a cooling chamber, a cooling fan installed on the top inner side of the cooling chamber, a spiral cooling tube installed on the inner side of the cooling chamber, a condensate tank installed on the lower side of the workbench, a water pump installed in the condensate tank, an output pipe connected to the output end of the water pump, the output pipe connected to the spiral cooling tube, a return pipe connected to the output end of the spiral cooling tube, the output end of the return pipe located on the top inner side of the condensate tank, and openings on both sides of the spiral cooling tube in the cooling chamber. This structural design is used for cooling straightened nickel-based alloys.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention uses a high-temperature resistant conveying roller and a high-temperature resistant clamping roller in a clamping and conveying mechanism. By using a spring to push the assembly plate, the high-temperature resistant clamping roller can adaptively press nickel-based alloys of different sizes, achieving stable clamping and effectively preventing material slippage during conveying and straightening. This prevents poor straightening effect and material surface damage caused by slippage.

[0021] 2. The present invention enables the nickel-based alloy to be rapidly heated to the annealing temperature through the resistance heating device of the annealing mechanism, and the preheating component draws high-temperature air from the heating box through the fan and uses the inclined structure of the air outlet to preheat the nickel-based alloy before it enters the heating box, thereby realizing heat utilization and improving energy utilization efficiency while ensuring the annealing effect.

[0022] 3. The straightening mechanism of the present invention consists of a first straightening component and a second straightening component working together. The first straightening component drives the upper straightening roller and the lower straightening roller to cooperate through a hydraulic cylinder to straighten the nickel-based alloy in the vertical direction. The second straightening component drives the straightening roller to clamp and straighten the nickel-based alloy on the left and right sides through an adjusting seat, thereby accurately straightening the nickel-based alloy from multiple directions and greatly improving the straightening effect and quality.

[0023] 4. The present invention arranges the annealing mechanism, clamping and conveying mechanism, straightening mechanism and cooling mechanism in an orderly manner, so that the entire process of nickel-based alloy from annealing to straightening and then cooling is continuous, realizing online annealing and straightening continuous production, effectively improving production efficiency, reducing manual intervention and process waiting time, and meeting the needs of large-scale industrial production.

[0036] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, an online annealing and straightening device for nickel-based alloys is provided. An annealing mechanism 2 is installed on one side of the top of the workbench 1. An assembly frame 3 is installed on the top of the workbench 1. A straightening mechanism 4 is installed on the assembly frame 3. A clamping and conveying mechanism 5 is installed between the straightening mechanism 4 and the annealing mechanism 2 on the assembly frame 3. A cooling mechanism 6 is installed at the output end of the straightening mechanism 4 on the workbench 1.

[0038] The annealing mechanism 2 includes a heating box 7, resistance heating devices 8 are installed on the upper and lower sides of the heating box 7, an inlet 9 is provided on the left side of the heating box 7, an outlet 10 is provided on the right side of the heating box 7, a clamping and conveying mechanism 5 is installed on the outside of the outlet 10, and a preheating component 11 is installed on the outside of the outlet 10 of the heating box 7.

[0039] The clamping and conveying mechanism 5 includes a high-temperature resistant conveying roller 501 and a high-temperature resistant clamping roller 502. The high-temperature resistant conveying roller 501 is fixedly installed on the workbench 1. An assembly plate 503 is installed on the top of the high-temperature resistant clamping roller 502. T-shaped slide bars 504 are installed on both sides of the top of the assembly plate 503. The T-shaped slide bars 504 are slidably installed on the assembly frame 3. Spring bases 505 are also installed on both sides of the top of the assembly plate 503. Springs 506 are installed inside the spring bases 505. A spring top seat 507 is installed on the free end of the top of the spring 506. The spring top seat 507 is locked on the assembly frame 3.

[0040] In this embodiment, during use, the nickel-based alloy is first fed into the nickel-based alloy annealing mechanism 2, so that the nickel-based alloy enters the heating box 7 from the inlet 9. The resistance heating device 8 in the heating box 7 quickly raises the nickel-based alloy to the annealing temperature. Then, the nickel-based alloy is output from the outlet 10 and directly enters the clamping and conveying mechanism 5, so that the bottom of the nickel-based alloy is located between the high-temperature resistant conveying roller 501 and the high-temperature resistant clamping roller 502, and is conveyed by the high-temperature resistant conveying roller 501. Under the effect of the spring 506, the high-temperature resistant clamping roller 502 pushes the assembly plate 503, and the assembly plate 503 pushes the high-temperature resistant clamping roller 502 to press on the nickel-based alloy, thereby clamping the nickel-based alloy and ensuring the stability of the nickel-based alloy during subsequent conveying, preventing the nickel-based alloy from sliding during subsequent straightening and affecting the straightening effect. The stable input of the nickel-based alloy is then sent to the straightening mechanism 4, where the nickel-based alloy is straightened. After straightening, it is input into the cooling mechanism 6 for cooling, and finally output from the cooling mechanism 6.

[0041] Example 2, as Figure 2 and Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the preheating component 11 includes a preheating box 12, with an inlet 13 on the left side and an outlet 14 on the right side. The outlet 14 is connected to the inlet 9. A preheating sleeve 15 is installed between the inlet 13 and the outlet 14 in the preheating box 12. The preheating sleeve 15 has several evenly arranged air outlets 16, which are inclined from left to right and from top to bottom. Fans 17 are installed on the upper and lower sides of the outlet 14 in the preheating box 12. The fans 17 are installed between the inner wall of the preheating box 12 and the outer surface of the preheating sleeve 15. The input end of the fans 17 is connected to a suction pipe 18, and the other side of the suction pipe 18 is connected to the inner side of the heating box 7.

[0042] In this embodiment, during use, the nickel-based alloy enters the preheating chamber 12 through the inlet 13 and then enters the heating chamber 7 through the outlet 14 and inlet 9. When the resistance heating device 8 rapidly raises the nickel-based alloy to the annealing temperature, the air inside the heating chamber 7 rises. The fan 17 draws the high-temperature air from the heating chamber 7 into the preheating chamber 12 through the suction pipe 18, and blows the high-temperature air onto the nickel-based alloy through the outlet 16 on the preheating jacket 15, thus preheating the nickel-based alloy. The outlets 16 are all inclined from left to right and from top to bottom, so that the blown air flows out from the inlet 13.

[0043] Example 3, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: the straightening mechanism 4 includes a plurality of first straightening components 19, which are evenly arranged on the assembly frame 3. The distance between two adjacent first straightening components 19 is equal, and a second straightening component 20 is provided between two adjacent first straightening components 19. There are two sets of second straightening components 20, and the two sets of second straightening components 20 are installed on the workbench 1.

[0044] In this embodiment, after the nickel-based alloy enters the straightening mechanism 4, the first straightening component 19 is used to straighten the nickel-based alloy by positioning it vertically, and the second straightening component 20 is used to straighten the nickel-based alloy by positioning it horizontally, thereby improving the straightening effect.

[0045] Example 4, as Figure 2 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 3: the first straightening assembly 19 includes a fixed roller seat 21 and a movable roller seat 22. The fixed roller seat 21 is fixedly installed on the workbench 1. A lower straightening roller 23 is installed inside the fixed roller seat 21. An upper straightening roller 24 is installed inside the movable roller seat 22. The upper straightening roller 24 is located directly above the lower straightening roller 23. A lifting plate 25 is installed on the top of the movable roller seat 22. A hydraulic cylinder 26 is installed on the assembly frame 3 at the corresponding lifting plate 25. A locking seat 27 is installed on the power output end of the hydraulic cylinder 26. The locking seat 27 is installed on the lifting plate 25.

[0046] In this embodiment, during use, the nickel-based alloy is output from the clamping and conveying mechanism 5 and enters the lower straightening roller 23. The hydraulic cylinder 26 is activated by control, which pushes the locking seat 27, the locking seat 27 pushes the lifting plate 25, the lifting plate 25 pushes the movable roller seat 22, and the movable roller seat 22 pushes the upper straightening roller 24 to press against the upper side of the nickel-based alloy. The lower straightening roller 23 and the upper straightening roller 24 straighten the nickel-based alloy in the vertical direction.

[0047] Example 5, as Figure 4As shown, this embodiment adds the following structure based on embodiment 3: guide rods 28 are installed on both sides of the lifting plate 25, and the assembly frame 3 is provided with guide holes 29 at the corresponding guide rods 28. The guide rods 28 are slidably installed in the guide holes 29, and threaded posts 30 are installed on the top of the guide rods 28. The guide rods 28 are locked with limit blocks 31 through the threaded posts 30.

[0048] In this embodiment, when the hydraulic cylinder 26 pushes the lock seat 27 and the lock seat 27 pushes the lifting plate 25 to move, the lifting plate 25 will synchronously drive the guide rods 28 on both sides to move up and down along the guide hole 29, thereby ensuring the verticality of the movement of the lifting plate 25, so that the upper straightening roller 24 can cooperate with the lower straightening roller 23 to straighten the nickel-based alloy in the vertical direction.

[0049] Example 6, as Figure 2 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 3: the second straightening component 20 includes adjusting seats 32 that are slidably installed on both sides of the worktable 1, roller seats 33 are installed on the inner side of the adjusting seats 32 on both sides, straightening rollers 34 are installed in the roller seats 33, and a transmission component 35 is installed between the two sets of second straightening components 20, and one set of second straightening components 20 is connected to a drive component 36.

[0050] In this embodiment, after the nickel-based alloy has undergone vertical straightening, the adjusting seats 32 on both sides are adjusted to push the roller seat 33, which in turn pushes the straightening roller 34 to clamp and straighten the left and right sides of the nickel-based alloy. Through the driving component 36 and the transmission component 35, the two sets of second straightening components 20 can be adjusted synchronously, thereby improving the straightening effect on the nickel-based alloy.

[0052] In this embodiment, during use, the drive assembly 36 drives the bidirectional threaded screw 38 to rotate along the bearing seat 39. The bidirectional threaded screw 38 then drives the nut moving seats 40 on both sides. The nut moving seats 40 drive the adjusting seat 32. The adjusting seat 32 pushes the roller seat 33. The roller seat 33 pushes the straightening roller 34 to clamp and straighten the left and right sides of the nickel-based alloy. Meanwhile, the other side of the rotating bidirectional threaded screw 38 drives the second straightening assembly 20 on the other side to adjust synchronously through the transmission assembly 35.

[0053] Example 8, as Figure 7 As shown, this embodiment adds the following structure based on embodiment 7: guide blocks 41 are provided on both sides of the nut moving seat 40, and guide grooves 42 are provided on the corresponding guide blocks 41 of the sliding groove 37.

[0054] In this embodiment, during the movement of the nut moving seat 40, the nut moving seat 40 will drive the guide blocks 41 on both sides to slide in the guide groove 42, so as to ensure the stability of the movement of the nut moving seat 40.

[0055] Example 9, as Figure 5 As shown, this embodiment adds the following structure based on embodiment 6: the drive assembly 36 includes a drive motor 43 installed at the bottom of the workbench 1, the power output end of the drive motor 43 is connected to a drive wheel 44, the drive wheel 44 is connected to a drive belt 45, the other side of the drive belt 45 is connected to a drive wheel 46, the drive wheel 46 is connected to one side of the bidirectional threaded screw 38, and the transmission assembly 35 includes transmission wheels 47 installed on the other side of the two sets of bidirectional threaded screws 38, and a transmission belt 48 is installed between the two sets of transmission wheels 47.

[0056] In this embodiment, during use, the drive motor 43 is started, which drives the drive wheel 44, which drives the drive belt 45, which drives the drive wheel 46, which drives a set of bidirectional threaded screws 38 to rotate. The other side of the rotating bidirectional threaded screws 38 drives the transmission wheel 47, which drives the transmission belt 48, which drives the transmission wheel 47 on another set of second straightening components 20 to rotate, thereby enabling the two sets of second straightening components 20 to perform adjustment and straightening work synchronously.

[0058] In this embodiment, after being straightened by the straightening mechanism 4, the nickel-based alloy enters the cooling box 49 through the opening 56 on one side. The water pump 53 draws the condensate from the condensate tank 52 into the output pipe 54, which then feeds it into the spiral cooling pipe 51. This allows the spiral cooling pipe 51 to cool the passing nickel-based alloy. At the same time, the cooling fan 50 is activated for air cooling, further improving the cooling effect. Finally, the condensate that has undergone heat exchange flows back to the condensate tank 52 through the return pipe 55.
