Description

Technical Field

[0001] The present invention relates to the technical field of annealing equipment, and particularly to an annealing device for nickel-based alloys. Background Art

[0002] An annealing furnace is a device used for heat treatment of metal materials. By heating a workpiece to a specific temperature, maintaining it for a certain period of time, and then slowly cooling it, the internal organizational structure of the workpiece is changed, thereby achieving the purpose of improving the material properties. This device is widely used in the processing of metal materials such as steel and nickel-based alloys, and is particularly suitable for the processing of steel for fasteners in fields such as automobiles and wind power, the processing of steel for high-performance machine tool guide rail components, and the production of steel for high-performance roadheader tools. The annealing process can effectively improve the toughness and ductility of these key components, reduce internal stress, and enhance the subsequent processing and service performance.

[0003] However, traditional annealing equipment has significant limitations in practical applications, especially in the above-mentioned high-demand application scenarios. Particularly in the workpiece cooling stage, since the equipment needs to be completely enclosed to ensure uniform cooling, the next batch of workpieces cannot enter the equipment for heating treatment in a timely manner and must wait for the current batch of workpieces to complete the entire cooling process. This operation mode not only prolongs the overall production cycle, but also reduces the overall efficiency of the production line, increasing production costs and time consumption.

[0004] The purpose of the present invention is to solve the problem that traditional annealing equipment cannot be opened during the workpiece cooling process, the next batch of workpieces needs to wait, and the working efficiency is low. Summary of the Invention

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: As Figures 1 to 15As shown in the figure, the present invention provides an annealing device for nickel-based alloys, which includes an annealing mechanism 1 and a loading and unloading mechanism 2. The annealing mechanism 1 includes a base 11, on which a housing 12 is provided. The housing 12 is provided with a first annealing part 13, a second annealing part 14, a third annealing part 15, and a fourth annealing part 16. A vertical movement mechanism 19 is installed on the side wall of the housing 12. The vertical movement mechanism 19 is connected to an electric heating block 110. The vertical movement mechanism 19 is used to drive the electric heating block 110 to move up and down in the housing 12, and the electric heating block 110 is used to heat the first annealing part 13, the second annealing part 14, the third annealing part 15, and the fourth annealing part 16.

[0040] The loading and unloading mechanism 2 is arranged on one side of the housing 12. The loading and unloading mechanism 2 includes a discharging mechanism 22 and a displacement mechanism 21. The discharging mechanism 22 is used to discharge or load the first annealing part 13, the second annealing part 14, the third annealing part 15, and the fourth annealing part 16. A lifting mechanism 212 is installed at the bottom of the discharging mechanism 22. The lifting mechanism 212 is used to drive the discharging mechanism 22 to lift or lower. The displacement mechanism 21 includes a transverse movement mechanism 211. The lifting mechanism 212 is installed at the bottom of the transverse movement mechanism 211. The transverse movement mechanism 211 is used to drive the lifting mechanism 212 and the discharging mechanism 22 installed above it to displace.

[0041] The annealing device for nickel-based alloys realizes the possibility of continuous operation by setting multiple independent annealing parts (the first annealing part 13, the second annealing part 14, the third annealing part 15, and the fourth annealing part 16). When the workpiece in one annealing part completes the heating process, the vertical movement mechanism 19 drives the electric heating block 110 to move up and down to adjust the heating position. At the same time, under the coordinated action of the lifting mechanism 212 and the displacement mechanism 21, the discharging mechanism 22 discharges the workpiece that has completed annealing and prepares for loading a new workpiece to be processed. During this process, each annealing part can operate independently, ensuring that even when one annealing part is in the cooling stage, other annealing parts can still continue to work without waiting for the entire device to complete a single cycle.

[0042] This design significantly improves the working efficiency and solves the problem that traditional annealing equipment cannot be opened during the cooling period of the workpiece, resulting in the need for the next batch of workpieces to wait. Since each annealing part can operate independently, the equipment can process multiple batches of workpieces simultaneously at different stages, greatly shortening the overall processing time. In addition, the design of the loading and unloading mechanism 2 makes the loading and unloading process more automated and efficient, reducing the need for manual intervention and further improving the production efficiency.

[0043] Further, as a preferred embodiment of the present invention rather than a limitation, the first annealing section 13 includes a first workbench 131, the second annealing section 14 includes a second workbench 141, the third annealing section 15 includes a third workbench 151, the fourth annealing section 16 includes a fourth workbench 161. The first workbench 131, the second workbench 141, the third workbench 151, and the fourth workbench 161 all include a baffle 1611. One side of the baffle 1611 is fixedly connected to a bearing plate 1612. The bearing plate 1612 is fixedly connected to a reinforcing rib 1613. One side of the reinforcing rib 1613 is fixedly connected to the baffle 1611. The widths of the bearing plates 1612 of the first workbench 131, the second workbench 141, the third workbench 151, and the fourth workbench 161 are all smaller than the inner cavity width of the housing 12.

[0044] The up-and-down moving mechanism 19 includes a first motor 191. A first lead screw 192 is installed on the rotor of the first motor 191. An internally threaded cylinder 193 is sleeved outside the first lead screw 192. The internally threaded cylinder 193 is threadedly connected to the first lead screw 192. The internally threaded cylinder 193 is fixedly connected to the electric heating block 110. A third sleeve 197 is sleeved outside the internally threaded cylinder 193. The third sleeve 197 is slidably connected to the internally threaded cylinder 193. A second sleeve 196 is sleeved outside the third sleeve 197. The second sleeve 196 is slidably connected to the third sleeve 197. A first sleeve 195 is sleeved outside the second sleeve 196. The first sleeve 195 is slidably connected to the second sleeve 196. The first annealing section 13 includes a first side plate 132. A first chute 1321 is formed in the first side plate 132. The second annealing section 14 includes a second side plate 142. A second chute 1421 is formed in the second side plate 142. The third annealing section 15 includes a third side plate 152. A third chute 1521 is formed in the third side plate 152. The fourth annealing section 16 includes a fourth side plate 162. A fourth chute 1621 is formed in the fourth side plate 162. The width of the fourth chute 1621 is the same as the width of the first sleeve 195. The width of the third chute 1521 is the same as the width of the second sleeve 196. The width of the second chute 1421 is the same as the width of the third sleeve 197.

[0045] The first annealing section 13, the second annealing section 14, the third annealing section 15, and the fourth annealing section 16 are respectively equipped with independent workbenches (the first workbench 131, the second workbench 141, the third workbench 151, and the fourth workbench 161). Each workbench is provided with a baffle 1611 and a carrier plate 1612, and the structural stability is enhanced by a reinforcing rib 1613. The carrier plate 1612 is used to carry workpieces. The up-and-down movement mechanism 19 is driven by a first motor 191, and the up-and-down movement of the electric heating block 110 is realized through the threaded connection between a first lead screw 192 and an internally threaded cylinder 193. The design of the multi-stage sleeve frames (the first sleeve frame 195, the second sleeve frame 196, and the third sleeve frame 197) ensures the stable and precise movement of the electric heating block 110 inside the housing 12. The chutes (the first chute 1321, the second chute 1421, the third chute 1521, and the fourth chute 1621) provide a guiding function for each stage of the sleeve frame, enabling the electric heating block 110 to accurately align with each annealing section for heating operations. The sleeve frames can block the chutes, avoiding mutual influence between each annealing section, reducing the mutual interference between different annealing sections, and improving the reliability of the overall device.

[0046] Furthermore, as a preferred embodiment of the present invention rather than a limitation, at least one positioning rod 194 is sleeved inside the electric heating block 110. Both ends of the positioning rod 194 are fixedly connected to the inner cavity of the housing 12. The electric heating block 110 is slidably connected to the positioning rod 194. A first cover plate 198, a second cover plate 199, and a third cover plate 1910 are sleeved outside the positioning rod 194. The first cover plate 198, the second cover plate 199, and the third cover plate 1910 are all slidably connected to the positioning rod 194. The carrier plate 1612 is provided with a step. The width between the step of the carrier plate 1612 of the fourth workbench 161 and the inner cavity side wall of the housing 12 is greater than the width between the step of the carrier plate 1612 of the third workbench 151 and the inner cavity side wall of the housing 12. The width between the step of the carrier plate 1612 of the third workbench 151 and the inner cavity side wall of the housing 12 is greater than the width between the step of the carrier plate 1612 of the second workbench 141 and the inner cavity side wall of the housing 12. The width between the step of the carrier plate 1612 of the second workbench 141 and the inner cavity side wall of the housing 12 is consistent with the width of the third cover plate 1910. The width between the step of the carrier plate 1612 of the third workbench 151 and the inner cavity side wall of the housing 12 is consistent with the width of the second cover plate 199. The width between the step of the carrier plate 1612 of the fourth workbench 161 and the inner cavity side wall of the housing 12 is consistent with the width of the first cover plate 198.

[0047] At least one positioning rod 194 is sleeved inside the electric heating block 110, and both ends of the positioning rod 194 are fixed in the inner cavity of the housing 12 to ensure that the electric heating block 110 can slide smoothly along the positioning rod 194. In addition, multiple layers of cover plates (the first cover plate 198, the second cover plate 199, the third cover plate 1910) are sleeved outside the positioning rod 194, and these cover plates are also slidably connected to the positioning rod 194. The bearing plate 1612 of each workbench is provided with a stepped structure, and the stepped widths of the bearing plates of different workbenches decrease in sequence and match the widths of the corresponding cover plates. Specifically, the stepped width of the bearing plate of the fourth workbench 161 is the largest, and decreases in sequence to the smallest stepped width of the bearing plate of the first workbench 131. This design enables the cover plate to cover the gap between the bearing plate and the inner cavity side wall of the housing when the electric heating block 110 moves downward, preventing heat dissipation and mutual interference. As the electric heating block 110 moves downward, the cover plates will stay at the corresponding annealing parts step by step, thereby realizing continuous annealing operation from top to bottom. The design of the cover plates effectively seals the gap between the bearing plate and the inner cavity side wall of the housing, reduces heat loss, and improves the heating efficiency and temperature uniformity of each annealing part. Secondly, the cover plates with different widths match the stepped widths of the bearing plates, ensuring that the cover plates can accurately stay at the corresponding annealing parts, avoiding heat conduction and mutual influence between different annealing parts, and improving the stability and reliability of the overall device. In addition, as the electric heating block 110 moves downward, the mechanism of the cover plates staying step by step makes the entire annealing process smoother, reduces the need for manual intervention, and further improves production efficiency.

[0048] Furthermore, as a preferred embodiment of the present invention rather than a limitation, the housing 12 includes a rear cover 121, and a plurality of support rods 1211 are installed on the side wall of the rear cover 121. The support rods 1211 are used to support the bearing plate 1612. The design of the support rods 1211 not only enhances the overall rigidity and stability of the device, but also effectively prevents the deformation or damage of the bearing plate under high-temperature conditions, ensuring that the device can maintain high efficiency and reliability during long-term operation.

[0049] Further, as a preferred embodiment of the present invention rather than a limitation, at least one snap ring 1614 is installed on one side of the baffle 1611. The unloading mechanism 22 includes a receiving table 221. A connecting block 226 is slidably connected inside the receiving table 221. A docking block 227 is installed on the connecting block 226. The shape of the top-down orthographic projection of the docking block 227 is the same as the inner cavity shape of the snap ring 1614. A second through groove 222 is formed in the side wall of the receiving table 221. A second slider 225 is slidably arranged in the second through groove 222. The second slider 225 is fixedly connected to the connecting block 226. A fourth lead screw 224 is sleeved inside the second slider 225. The fourth lead screw 224 is threadedly connected to the second slider 225. One end of the fourth lead screw 224 is installed with a fourth motor 223. The fourth motor 223 is fixedly connected to the receiving table 221. The design of the snap ring 1614 and the docking block 227 ensures that the unloading mechanism 22 can be accurately docked with the bearing plates 1612 of each workbench, reducing the risk of workpiece offset or damage during loading and unloading, and improving the reliability and safety of loading and unloading. When the fourth motor 223 is started, the fourth lead screw 224 drives the second slider 225 and its connected connecting block 226 and docking block 227 to slide along the second through groove 222, thereby pulling the workbench corresponding to the baffle 1611 through the docking block 227 and the snap ring 1614 to realize the unloading operation of the workpiece. Specifically, after the docking block 227 is inserted into the snap ring 1614, the fourth motor 223 drives the fourth lead screw 224 to move the docking block 227 backward, driving the entire workbench (such as the first workbench 131, the second workbench 141, etc.) to move, completing the unloading process of the workpiece. When the fourth motor 223 rotates in reverse, the fourth lead screw 224 rotates in the reverse direction, pushing the docking block 227 forward to place a new workpiece on the workbench, completing the loading operation. By driving the fourth lead screw 224 with the fourth motor 223, the automatic movement of the docking block 227 is realized, greatly simplifying the operation process, reducing the need for manual intervention, and further improving the production efficiency. In addition, the design of the second through groove 222 and the second slider 225 makes the entire system run more smoothly, reduces mechanical wear and failure rate, and extends the service life of the equipment.

[0050] Optionally, in some embodiments, the connecting block 226 is provided with a groove 2261. The docking block 227 is slidably arranged in the groove 2261. A first elastic body 2271 is installed at the bottom of the docking block 227. The first elastic body 2271 is fixedly connected to the groove 2261. During the docking process, if there is a slight positional deviation between the docking block 227 and the snap ring 1614, the first elastic body 2271 can absorb these minute errors, enabling the docking block 227 to smoothly enter the inside of the snap ring 1614. Once the docking is successful, the resilience provided by the first elastic body 2271 ensures that the docking block 227 fits tightly against the snap ring 1614, enhancing the stability of the connection.

[0051] Further, as a preferred embodiment of the present invention rather than a limitation, the lifting mechanism 212 includes a sliding plate 2124. An expansion frame 2123 is installed on the sliding plate 2124. One side of the bottom of the expansion frame 2123 is hinged to the sliding plate 2124, and a moving block 2125 is hinged to the other side of the bottom of the expansion frame 2123. The moving block 2125 is slidably connected to the sliding plate 2124. A third motor 2121 is installed on the sliding plate 2124, and a third lead screw 2122 is installed on the rotor of the third motor 2121. The third lead screw 2122 is sleeved in the moving block 2125, and the moving block 2125 is threadedly connected to the third lead screw 2122. Guide rails 2126 are installed on both sides of the moving block 2125, and the guide rails 2126 are slidably connected to the moving block 2125. When the third motor 2121 is started, the third lead screw 2122 rotates, driving the moving block 2125 to slide along the sliding plate 2124. Guide rails 2126 are installed on both sides of the moving block 2125 to ensure that the moving block 2125 can slide smoothly. As the moving block 2125 moves, the expansion frame 2123 realizes the expansion and contraction action through the change of the hinge point, thereby changing its height, and further driving the unloading mechanism 22 to perform the lifting or lowering operation. This design enables the unloading mechanism 22 to move precisely between different heights, adapt to the height requirements of different workbenches, and complete the loading and unloading tasks of workpieces.

[0052] Further, as a preferred embodiment of the present invention rather than a limitation, the transverse movement mechanism 211 includes a bottom plate 2111. Support plates 2112 are installed on both sides of the bottom plate 2111. The support plates 2112 are provided with first through grooves 2113. A first slider 2116 is slidably connected in the first through grooves 2113. The first slider 2116 is fixedly connected to the sliding plate 2124. The sliding plate 2124 is slidably connected to the bottom plate 2111. A second lead screw 2115 is sleeved in the first slider 2116. The second lead screw 2115 is threadedly connected to the first slider 2116. One end of the second lead screw 2115 is installed with a second motor 2114, and the second motor 2114 is fixedly connected to the support plate 2112. When the second motor 2114 is started, the second lead screw 2115 rotates, driving the first slider 2116 to slide along the first through groove 2113, thereby driving the sliding plate 2124 and the lifting mechanism 212 and the unloading mechanism 22 above it to move in the horizontal direction. This design enables the unloading mechanism 22 to move precisely between different positions, adapt to the position requirements of different workbenches, and complete the loading and unloading tasks of workpieces.

[0053] The implementation manner of the second embodiment is as follows:

[0054] The difference between the second embodiment and the first embodiment is that a buffer mechanism 228 is installed on the inner wall of the material receiving table 221. The buffer mechanism 228 includes a cylinder body 2281, a second elastic body 2282 is installed in the cylinder body 2281, and a contact block 2283 is installed at one end of the second elastic body 2282. When the unloading mechanism 22 performs the loading and unloading operation of the workpiece, especially when the docking block 227 is docked with the snap ring 1614, the workpiece is moved onto the material receiving table 221. During this process, if there is an impact or collision between the connecting block 226 and the material receiving table 221, the contact block 2283 will first come into contact with the connecting block 226, and absorb the impact energy through the second elastic body 2282, reducing the damage to the workpiece and the equipment itself, and improving the durability of the equipment and the quality of the workpiece.

[0055] The implementation method of the third embodiment is as follows:

[0056] The difference between the third embodiment and the first embodiment is that a second pipe body 18 is installed between the fourth side plate 162 and the second side plate 142, and a first pipe body 17 is installed between the third side plate 152 and the first side plate 132. The structures of the first pipe body 17 and the second pipe body 18 are the same, and a valve 171 is installed in the first pipe body 17. When the workpiece in the fourth annealing section 16 cools down, the valve 171 of the second pipe body 18 can be opened to transfer the temperature of the fourth annealing section 16 to the second annealing section 14, accelerating the cooling of the workpiece and preheating the second annealing section 14 at the same time. Similarly, when the third annealing section 15 needs to cool down, the valve 171 in the first pipe body 17 can be opened to transfer the heat to the first annealing section 13 to achieve a similar effect, improving the overall energy utilization rate

[0057] Specifically, the working principle of the present invention is as follows:

[0058] The annealing device includes a plurality of independent annealing sections (the first annealing section 13, the second annealing section 14, the third annealing section 15, and the fourth annealing section 16), and each annealing section is equipped with an independent workbench (the first workbench 131, the second workbench 141, the third workbench 151, and the fourth workbench 161). The up and down moving mechanism 19 is driven by the first motor 191, and the precise up and down movement of the electric heating block 110 is realized through the threaded connection between the first lead screw 192 and the internal thread cylinder 193 to align with each annealing section for heating operation. The multi-stage sleeve frames (the first sleeve frame 195, the second sleeve frame 196, the third sleeve frame 197) and the sliding grooves (the first sliding groove 1321, the second sliding groove 1421, the third sliding groove 1521, the fourth sliding groove 1621) plus the cover plate design effectively prevent heat dissipation and mutual interference between different annealing sections.

[0059] The unloading mechanism 22 is accurately docked with the snap rings 1614 on each workbench through the connecting blocks 226 and docking blocks 227 in the receiving table 221 to achieve the loading and unloading of workpieces. The fourth motor 223 drives the fourth lead screw 224, driving the second slider 225 and the connecting blocks 226 and docking blocks 227 connected thereto to slide along the second through groove 222, thereby completing the unloading or loading operation of the workpieces. The design of the first elastic body 2271 makes the docking process smoother, reduces the influence caused by position deviation, and improves the reliability and safety of the operation.

[0060] The lifting mechanism 212 is driven by the third motor 2121 to drive the third lead screw 2122, driving the moving block 2125 to slide along the slide plate 2124. The telescopic frame 2123 adjusts its height through the change of the hinge points to complete the lifting or lowering operation of the unloading mechanism 22. The transverse movement mechanism 211 is driven by the second motor 2114 to drive the second lead screw 2115, driving the first slider 2116 to slide along the first through groove 2113, realizing the precise movement of the slide plate 2124 and the lifting mechanism 212 and unloading mechanism 22 above it in the horizontal direction, adapting to the position requirements of different workbenches, and completing the loading and unloading tasks of workpieces. The overall design realizes an automated and efficient workpiece processing flow, significantly improving the production efficiency and the reliability of the equipment.

[0061] In summary, the present invention solves the problem that the traditional annealing equipment cannot be opened during the cooling of workpieces, the next batch of workpieces needs to wait, and the working efficiency is low.

[0062] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information. In addition, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0063] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations are also regarded as the protection scope of the present invention.
