Description

Technical Field

[0001] This application relates to the field of warm forging, and more particularly to a warm forging heating system for axle machining. Background Technology

[0002] Warm forging is a process in which metal is forged at or near its recrystallization temperature, but above room temperature. The temperature range is typically 200℃ to 850℃ for ferrous metals and room temperature to 350℃ for non-ferrous metals. Compared to cold and hot forging, warm forging offers advantages such as moderate deformation resistance, high forging precision, and minimal oxidation and decarburization. It can form small to medium-sized complex precision forgings from materials with high deformation resistance, such as stainless steel, high-carbon steel, and high-alloy steel.

[0003] In related technologies, such as the forging heating system disclosed in Chinese patent document CN104550621A, the forging is typically heated directly to the required forging temperature before die forging. However, impurities such as residual cutting oil, emulsion, moisture, and dust on the surface of the forging are easily trapped into the surface layer of the forging at high temperatures. During the process of directly heating the forging to a high temperature (such as 700℃), a thick oxide scale is easily formed on the surface, causing material loss and affecting the dimensional accuracy and surface finish of the final forging. Therefore, improvements are needed. Summary of the Invention

[0004] In order to improve the problem that oxide scale is easily generated in forgings during heated forging, which affects the forging quality and surface quality of forgings, this application provides a warm forging heating system for axle machining.

[0005] The warm forging heating system for axle machining provided in this application adopts the following technical solution: A warm forging heating system for axle machining includes a conveyor belt and a preheating section, a spraying section, and a heating section arranged sequentially along the conveying direction of the conveyor belt. The preheating section is used to remove impurities from the surface of the forging. The spraying section is used to spray a graphene suspension onto the surface of the forging to form a protective lubricating coating. The heating section is used to heat the forging coated with the protective lubricating coating.

[0006] By adopting the above technical solution, the forging is first heated to 170℃~270℃ in the preheating section, so that all the residual cutting oil, emulsion, moisture, dust and other impurities on the surface can be evaporated and dried, avoiding the problem of impurities being trapped in the coating and causing the coating to peel, fall off or have poor adhesion; low temperature preheating can eliminate thick oxidation in the early stage, and the steel will hardly produce a thick oxide scale, with a clean and flat surface, laying a good base for subsequent spraying; at the same time, gentle heating can eliminate the internal stress of the billet and avoid cracking due to rapid heating in the later stage.

[0007] Subsequently, in the spraying section, a graphene suspension is sprayed onto the surface of the forging, forming a complete and dense protective lubricating coating. Finally, in the heating section, the coated forging is heated to a warm forging temperature of approximately 700°C. During the secondary heating process, the graphene coating becomes further denser and more stable, and plays a solid-state lubricating role during forging, reducing friction between the die and the blank, preventing scratches and sticking, and simultaneously reducing forging pressure.

[0008] When graphene is sprayed onto the preheated forging, the high temperature of the forging itself causes the water or solvent in the graphene suspension to evaporate instantly, and the coating to quickly set, preventing the coating from flowing, piling up, or becoming uneven in thickness. Overall, the three processes of preheating, spraying, and heating are sequentially connected, first cleaning the surface, then establishing a protective barrier, and finally heating and shaping, effectively improving the forging quality and surface quality of the forging.

[0009] Optionally, the conveyor belt includes two parallel conveyor belts, the middle of which is located within the spraying section. The preheating section is connected to two discharge channels, each corresponding to one of the conveyor belts, and the discharge channels are located above the end of the conveyor belts near the preheating section.

[0010] By adopting the above technical solution and using parallel conveyor belts, the system's conveying efficiency is improved. Each conveyor belt corresponds to a discharge channel, realizing automatic connection between the preheating section and the spraying section, eliminating the need for manual handling and improving the degree of production automation.

[0011] Optionally, the conveyor belt has a plurality of mounting holes through it, and the inner wall of the mounting holes is provided with a support ring, which is used to support the forgings in the mounting holes.

[0012] By adopting the above technical solution, the preheated forgings fall directly from the discharge channel into the corresponding mounting holes of the conveyor belt, where they are supported by support rings, achieving orderly conveying of individual forgings. The mounting holes provide positioning and accommodating space for the forgings, and the support rings support the forgings from the bottom, keeping them stable during conveying and preventing rolling or displacement.

[0013] Optionally, the conveyor belt is provided with a heat transfer tube located below the conveyor belt. The end of the heat transfer tube is connected to the top of the conveyor belt through a mounting hole. One end of the heat transfer tube is located below the discharge channel, and the opening of the end of the heat transfer tube is aligned with the outlet of the discharge channel. The opening of the other end of the heat transfer tube is aligned with the spraying section.

[0014] By adopting the above technical solution, the heat transfer tube absorbs the heat flowing out of the preheating section from the discharge channel and transfers this heat, which would otherwise be wasted, to the spraying section. One end of the heat transfer tube is located below the discharge channel with its opening aligned with the discharge channel outlet, while the other end is aligned with the spraying section, thus guiding the heat lost in the preheating section to the spraying section. During the graphene spraying process in the spraying section, the forging is affected by the heat emitted by the heat transfer tube, allowing it to maintain a high temperature of approximately 300°C during spraying. This achieves efficient heat recovery and utilization, avoids heat loss, and reduces overall energy consumption.

[0015] Optionally, the spraying section includes a spraying box and several spray guns. The conveyor belt passes through the spraying box, and the spray guns are located on the inner top wall of the spraying box. The spray guns are aligned with the conveyor belt, and two spray guns are provided above each conveyor belt. The two spray guns are arranged at intervals along the length of the conveyor belt.

[0016] By adopting the above technical solution, the spray box provides a closed environment for the spraying operation, preventing the graphene suspension from spreading and polluting the surrounding environment. Two spray guns are installed above each conveyor belt, allowing the forgings to pass through the spraying areas of the two spray guns sequentially during the conveying process, improving the spraying coverage and uniformity.

[0017] Optionally, the spraying box is equipped with a conveying device for transporting forgings between two conveyor belts. The conveying device includes a flipping component and two moving components. The flipping component is located between the two conveyor belts and is used to flip the forgings on the conveyor belts. The two moving components are located in the spraying box and correspond one-to-one with the conveyor belts. The moving components are used to transport forgings between the conveyor belts and the flipping component.

[0018] By adopting the above technical solution, when the forgings enter the coating box under the drive of the conveyor belt, one of the spray guns first sprays graphene onto the upward-facing side of the forging. Then, the forgings move to the handling device, where one moving component moves the forgings from the conveyor belt to a flipping component, which flips them so that the uncoated side of the forging is facing upwards. Next, another moving component maintains this state as it moves the forging to another conveyor belt, where another spray gun on that conveyor belt sprays the reverse side of the forging. This achieves omnidirectional double-sided coating of the forgings, ensuring that the forgings leaving the coating box are uniformly covered with a graphene coating. The forgings on the two conveyor belts are flipped and exchanged via the handling device, enabling continuous flow operation and improving coating efficiency.

[0019] Optionally, the flipping assembly includes a mounting base, a flipping motor, a flipping plate, and a support platform. The mounting base is located in the spray box and between the two conveyor belts. The flipping motor is mounted on the mounting base, and its output shaft is parallel to the conveyor belts. The output end of the flipping motor is connected to one end of the flipping plate to drive the flipping plate to flip. Both sides of the flipping plate are provided with flipping suction cups, and the flipping plate can rotate to be above one of the conveyor belts. The support platform is located between the mounting base and the other conveyor belt, and the other side of the flipping plate can rotate to be above the support platform. One of the moving components is used to transport the forging between the conveyor belts and the flipping plate, and the other moving component is used to transport the forging between the other conveyor belt and the support platform.

[0020] By adopting the above technical solution, in the initial state, the flipping plate is located above one of the conveyor belts, with its underside aligned with one of the forgings on the conveyor belt. The flipping suction cups on the flipping plate adsorb the forging in the mounting hole. The flipping motor drives the flipping plate to rotate, causing the suction cups to hold the forging and remove it from the conveyor belt. When the flipping plate rotates 180°, its reverse side faces upward, supporting the forging. At this point, the forging has been flipped, and the flipping plate is positioned directly above the support platform. A moving component on the other conveyor belt moves the forging with its reverse side facing upward onto the other conveyor belt, realizing the exchange of forgings between the two conveyor belts.

[0021] As the tilting plate rotates towards the support platform, the moving component moves the forgings from the conveyor belt to the support platform. The front of the tilting plate faces down and holds the forgings on the support platform, thus loading the forgings. The tilting plate then resets, rotating 180° with the forgings on the support platform back above the conveyor belt. At this point, the front of the tilting plate, holding the forgings on the support platform, faces upwards and is removed by the moving component onto the conveyor belt, thus unloading the forgings. Simultaneously, the back of the tilting plate faces down and holds new forgings for loading. This allows for simultaneous unloading on one side of the tilting plate and loading on the other, enabling full-station operation and significantly improving work efficiency.

[0022] Optionally, a support suction cup is provided on the top wall of the support platform.

[0023] By adopting the above technical solution, the support suction cup can firmly adsorb the forging onto the support platform, preventing the flipping plate from shifting when adsorbing the forging on the support platform, improving the stability of the forging on the support platform, and ensuring the reliability of the flipping and handling process.

[0024] Optionally, the moving component includes a moving frame, a driving component, and a lifting cylinder. The moving frame is installed inside the spray box and spans across the conveyor belt. The spray gun is located on both sides of the moving frame. The lifting cylinder is connected to the moving component through the driving component. The driving component is used to drive the lifting cylinder to move along the width direction of the conveyor belt. The output end of the lifting cylinder is equipped with a moving suction cup for adsorbing forgings. The lifting cylinder is used to drive the moving suction cup to move up and down.

[0025] By adopting the above technical solution, the moving frame spanning the conveyor belt provides a mounting base for the drive unit and the lifting cylinder. The drive unit drives the lifting cylinder to move along the width of the conveyor belt, enabling the moving suction cup to reciprocate between the conveyor belt and the tilting assembly; the lifting cylinder drives the moving suction cup to move up and down, realizing the lifting and lowering of the forging. By adsorbing the forging with the moving suction cup, damage to the surface of the forging caused by mechanical clamping can be avoided, and the adsorption method is more adaptable to forgings of different shapes.

[0026] Optionally, the driving component includes a moving motor, a moving rod, and a moving block. The moving motor is mounted on the moving frame. The moving rod is arranged along the width direction of the conveyor belt, and the end of the moving rod is rotatably connected to the moving frame. The output end of the moving motor is coaxially fixed with one end of the moving rod to drive the moving rod to rotate. The moving block is slidably connected to the moving frame, sleeved on the moving rod, and threadedly connected to the moving rod. The rotation of the moving rod drives the moving block to move along the length direction of the moving rod. The lifting cylinder is mounted on the moving block.

[0027] By adopting the above technical solution, the moving motor drives the moving rod to rotate, and the moving rod drives the moving block to slide along the length of the moving rod through a threaded connection, thereby driving the lifting cylinder and the moving suction cup to move along the width of the conveyor belt. This screw drive method provides smooth movement and high positioning accuracy, and can precisely control the displacement of the moving suction cup between the conveyor belt and the flipping assembly, ensuring the accuracy and reliability of forging handling.

[0028] In summary, this application includes at least one of the following beneficial effects: 1. The forging is heated to 170℃~270℃ in the preheating section to remove surface impurities. With the help of heat transfer tubes, the forging is kept at a suitable temperature of about 300℃ in the spraying section. The water or solvent in the graphene suspension evaporates instantly, the coating is quickly set, does not flow or accumulate, has uniform thickness and strong adhesion, which significantly improves the quality of the protective lubricating coating. 2. The graphene coating forms a complete and dense protective layer on the surface of the forging, which isolates oxygen during the subsequent heating process to 700℃ forging temperature, reducing oxide scale from the source and ensuring a smooth surface and accurate dimensions of the forging; at the same time, it plays a solid lubricating role during forging, reducing friction between the die and the billet, preventing scratches and sticking to the die, and reducing forging pressure. 3. Through the cooperation of the flipping component and the moving component in the conveying device, the forgings are automatically flipped and exchanged between the two conveyor belts, so that the front and back sides of the forgings are sprayed by the spray gun respectively, realizing all-round double-sided spraying; and the loading and unloading of the flipping plate are carried out simultaneously, realizing full-station operation and greatly improving the spraying efficiency.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a warm forging heating system for axle machining. (Refer to...) Figure 1 and Figure 2The warm forging heating system for axle machining includes a conveyor belt 1 and a preheating section 2, a spraying section 3, and a heating section 4 arranged sequentially along the conveying direction of the conveyor belt 1. The preheating section 2 heats the forging to 170℃~270℃ to remove cutting oil, emulsion, moisture, dust, and other impurities from the forging surface, while simultaneously gently heating the forging to eliminate internal stress in the billet. The spraying section 3 sprays a graphene suspension onto the forging surface to form a protective lubricating coating. The heating section 4 heats the forging coated with the protective lubricating coating to a warm forging temperature of approximately 700℃.

[0033] Reference Figure 1 and Figure 3 The conveyor belt 1 includes two conveyor belts 11 arranged parallel to each other. The middle part of the conveyor belt 11 is located within the spraying section 3. The preheating section 2 is connected to two discharge channels 21, which correspond one-to-one with the conveyor belts 11. The discharge channels 21 are located above the end of the conveyor belt 11 closest to the preheating section 2. The preheated forgings fall from the discharge channels 21 onto the corresponding conveyor belts 11. Several mounting holes 111 are provided through the conveyor belts 11, spaced apart along the length of the conveyor belt 11. Support rings 112 are provided on the inner wall of the mounting holes 111 to support the forgings in the mounting holes 111, keeping the forgings stable during conveying.

[0034] Reference Figure 1 and Figure 2 A heat transfer pipe 5 is installed on the conveyor belt 11, located below the conveyor belt 11. The end of the heat transfer pipe 5 is connected to the top of the conveyor belt 11 through a mounting hole 111. One end of the heat transfer pipe 5 is located below the discharge channel 21, with its opening aligned with the outlet of the discharge channel 21; the other end of the heat transfer pipe 5 is aligned with the spraying section 3. Thus, the heat transfer pipe 5 absorbs heat from the preheating section 2 flowing out of the discharge channel 21 and transfers this heat to the spraying section 3. During the graphene spraying process in the spraying section 3, the forging is maintained at a high temperature of approximately 300°C due to the heat emitted by the heat transfer pipe 5. This ensures that the forging remains at a suitable temperature of around 300°C during the spraying process, allowing the water or solvent in the graphene suspension to evaporate instantly and the coating to quickly solidify, preventing coating dripping, accumulation, or uneven thickness.

[0035] Reference Figure 1 and Figure 2 The spraying section 3 includes a spraying box 31 and several spray guns 32. A conveyor belt 11 passes through the spraying box 31, and the spray guns 32 are mounted on the inner top wall of the spraying box 31, aligned with the conveyor belt 11. Two spray guns 32 are positioned above each conveyor belt 11, spaced apart along the length of the conveyor belt 11. When the forging enters the spraying box 31 driven by the conveyor belt 11, it first passes under the first spray gun 32 for initial spraying, and then continues moving.

[0036] Reference Figure 2 and Figure 3 The spraying box 31 is equipped with a conveying device 6, which is used to transport the forgings between two conveyor belts 11. The conveying device 6 includes a flipping assembly 61 and two moving assemblies 62. The flipping assembly 61 is located between the two conveyor belts 11 and is used to flip the forgings on the conveyor belts 11. The two moving assemblies 62 are located in the spraying box 31, and each moving assembly 62 corresponds to one of the conveyor belts 11. The moving assemblies 62 are used to transport the forgings between the conveyor belts 11 and the flipping assembly 61.

[0037] Reference Figure 3 and Figure 4 The flipping assembly 61 includes a mounting base 611, a flipping motor 612, a flipping plate 613, and a support platform 614. The mounting base 611 is located in the spray box 31, between two conveyor belts 11. The flipping motor 612 is mounted on the mounting base 611, and its output shaft is parallel to the conveyor belts 11. The output end of the flipping motor 612 is connected to one end of the flipping plate 613, driving the flipping plate 613 to flip around a horizontal axis. Both sides of the flipping plate 613 are provided with flipping suction cups 6131. ​​The flipping plate 613 can rotate to above one of the conveyor belts 11 (first working position) and also to above the support platform 614 (second working position). The support platform 614 is located between the mounting base 611 and the other conveyor belt 11, and its top wall is provided with support suction cups 6141 for adsorbing and fixing forgings on the support platform 614.

[0038] Reference Figure 3 and Figure 4 The moving assembly 62 includes a moving frame 621, a drive unit 622, and a lifting cylinder 623. The moving frame 621 is located inside the spray booth 31 and spans across the conveyor belt 11, with spray guns 32 located on either side of the moving frame 621. The lifting cylinder 623 is connected to the moving frame 621 via the drive unit 622, which drives the lifting cylinder 623 to move along the width of the conveyor belt 11. A movable suction cup 6231 for adsorbing forgings is installed at the output end of the lifting cylinder 623, and the lifting cylinder 623 drives the movable suction cup 6231 to move up and down.

[0039] The flipping suction cup 6131, the supporting suction cup 6141, and the moving suction cup 6231 have the same structure, all consisting of a cylinder and a suction cup. The extension and retraction of the cylinder can extract gas from the suction cup or send gas into the suction cup to achieve adsorption or release of the forging. In this embodiment, the suction cup is a silicate fabric fiber suction cup to withstand high temperature and achieve stable transport of the forging.

[0040] Reference Figure 3 and Figure 4Specifically, the driving component 622 includes a moving motor 6221, a moving rod 6222, and a moving block 6223. The moving motor 6221 is mounted on the moving frame 621. The moving rod 6222 is arranged along the width direction of the conveyor belt 11, and its end is rotatably connected to the moving frame 621. The output end of the moving motor 6221 is coaxially fixed to one end of the moving rod 6222, driving the moving rod 6222 to rotate. The moving block 6223 is slidably connected to the moving frame 621, sleeved on the moving rod 6222, and threadedly connected to it. When the moving rod 6222 rotates, the threaded connection drives the moving block 6223 to slide along the length direction of the moving rod 6222. A lifting cylinder 623 is mounted on the moving block 6223 and moves with it.

[0041] The implementation principle of a warm forging heating system for axle machining according to an embodiment of this application is as follows: After preheating and impurity removal in the preheating section 2, the forging falls into the mounting hole 111 of the conveyor belt 11 through the discharge channel 21 and is supported by the support ring 112. The conveyor belt 11 feeds the forging into the spraying box 31. First, the first spray gun 32 located above the conveyor belt 11 sprays graphene onto the upward-facing side of the forging. Subsequently, the forging moves to the conveying device 6.

[0042] With the reverse side of the flip plate 613 facing down, it automatically picks up the forging from the conveyor belt 11. Then, the flipping motor 612 starts, driving the flip plate 613 to rotate 180°. The forging rotates with the flip plate 613, so that the originally uncoated, downward-facing reverse side of the forging is now facing up. At this time, the flip plate 613 is located above the support platform 614. The moving component 62 corresponding to the other conveyor belt 11 starts, and its moving suction cup 6231 moves to the flip plate 613, picks up the reverse-facing forging, and moves it to the other conveyor belt 11. This conveyor belt 11 continues to move forward, delivering the forging to the area below the second spray gun 32 corresponding to this conveyor belt 11 for graphene coating on the reverse side. This completes the double-sided, all-around coating of the forging.

[0043] Meanwhile, as the tilting plate 613 rotates from the first working position to the second working position, the moving component 62 corresponding to the second conveyor belt 11 transports the next forging from the conveyor belt 11 to the support platform 614, where the support suction cup 6141 holds the forging in place. When the tilting plate 613 rotates to the second working position, the tilting suction cup 6131 on the front of the tilting plate 613 faces downward, holding the forging on the support platform 614, thus loading. Subsequently, the tilting motor 612 drives the tilting plate 613 to rotate 180° in the opposite direction to return to the first working position. At this time, the forging held on the front of the tilting plate 613 faces upward, and is removed by the moving component 62 at the first working position and sent to the first conveyor belt 11, thus unloading; at the same time, the tilting suction cup 6131 on the back of the tilting plate 613 faces downward, re-attaching the next forging on the first conveyor belt 11 for the next loading. This allows the tilting plate 613 to unload on one side while loading on the other, with loading and unloading occurring simultaneously, achieving continuous operation at full capacity.

[0044] After the coating is completed, the forging is moved out of the coating box 31 by the conveyor belt 11 and enters the heating section 4, where it is heated to a warm forging temperature of approximately 700°C. During this process, the graphene coating is further cured and densified to form a stable protective and lubricating layer, after which the forging enters the forging process.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
