Description

Technical Field

[0001] This invention relates to the field of aluminum alloy forging production technology, and in particular to a transfer and heat preservation device for aluminum alloy forgings. Background Technology

[0002] In the mass production of complex aluminum alloy forgings, maintaining the temperature stability of the forgings after forging is crucial for ensuring the effectiveness of subsequent processes (such as aging treatment) and the mechanical properties and microstructure uniformity of the final product. Currently, the common production process involves the workpiece being formed on a forging press and then transferred to a dedicated electric holding furnace for heat preservation. However, this model has significant bottlenecks: on the one hand, equipping a sufficient number of electric holding furnaces would significantly increase equipment investment and floor space costs; on the other hand, and more importantly, the high-temperature workpiece undergoes intense heat exchange with the surrounding low-temperature environment during its transfer from the forging station to the holding furnace in the open space, resulting in rapid heat loss. This uncontrolled temperature drop not only increases the energy and time costs of subsequent heat preservation processes but also directly affects the internal quality of the forgings, causing performance fluctuations.

[0003] To mitigate temperature drops during transport, existing technologies often employ a simple method of manually wrapping the surface of forgings with insulating materials (such as insulating cotton or ceramic fiber blankets). However, this method has significant drawbacks in practical applications: First, the surface temperature of forgings immediately after demolding is extremely high, posing a serious risk of burns to manual operation at close range, thus imposing stringent requirements on labor protection. Second, manual wrapping is inefficient, with poor sealing and consistency, making it difficult to adapt to the pace of automated, fast-paced production lines, thus becoming a bottleneck restricting overall production efficiency. Finally, the insulation effect of simple wrapping is limited and uncontrollable, failing to effectively isolate air convection, resulting in significant heat loss. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a transfer and heat preservation device for aluminum alloy forgings, which solves the above-mentioned technical problems.

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1 to 3 As shown, the present invention provides a transfer and heat preservation device for aluminum alloy forgings, which mainly includes a forging press 1; A movable worktable is located on one side of the forging press 1 and is used to carry and transport workpieces; A heat insulation cover assembly is used to keep the workpiece located on the movable worktable warm; Robotic arm 8 is used to grasp and move the heat insulation cover assembly; The heat insulation cover assembly includes a heat insulation cover 19, a bottom frame 18 fixedly connected to the bottom of the heat insulation cover 19, and a lifting frame connected to the top of the heat insulation cover 19 via an elastic lifting mechanism. A gas regulation passage is provided between the hoisting frame and the insulation cover 19. The gas regulation passage is configured such that: during the first period when the robotic arm 8 drives the hoisting frame to rise, the high-temperature gas inside the insulation cover 19 can be discharged through the gas regulation passage; during the second period of rising, the gas regulation passage is closed.

[0022] It is worth noting that by setting up a dedicated heat preservation cover assembly gripped by a robotic arm, the automated and integrated heat preservation process of the workpiece during transfer between the forging station and subsequent stations is achieved. This completely eliminates the traditional reliance on independent heat preservation furnaces or manual wrapping, seamlessly integrating the heat preservation process into the production line, significantly improving production continuity and efficiency. Effective control of heat loss during transfer: The heat preservation cover assembly can directly and enclose the high-temperature workpiece that has just finished forging, forming a local microenvironment. This greatly reduces heat exchange between the workpiece and the low-temperature external environment during transfer due to radiation and convection, thereby ensuring the stability and consistency of the workpiece temperature.

[0023] The design of the gas regulation channel allows for the orderly discharge of high-temperature gas inside the insulation cover 19 during the initial lifting stage, and automatic sealing during the later lifting stage. This prevents the disorderly dissipation of hot air inside the cover and the backflow of cold air from the outside, further optimizing the insulation and energy-saving effects.

[0024] In this embodiment, the movable worktable is located on one side of the forging press 1 and is used to transfer the high-temperature workpiece that has just been forged to the next process. The movable worktable includes a movable platform 2 and a sliding plate 3 disposed on the movable platform 2. The sliding plate 3 can slide along a specific track on the movable platform 2 by means of a screw 4 driven by a motor 305, and a support plate 6 can be placed on it to support the workpiece.

[0025] The heat insulation cover assembly is used to keep the workpiece warm during transport, reducing heat loss. Specifically, the bottom of the heat insulation cover 19 is fixedly connected to the bottom frame 18, and the top is fixedly connected to the fixed plate 13 via the inner connecting frame 17, thus forming a rigid cover structure. The lifting frame (U-shaped frame 12) is connected to the fixed plate 13 via the elastic lifting mechanism. The elastic lifting mechanism includes a slide rod 14 fixed to the bottom of the U-shaped frame 12 and a guide sleeve (or an open movable groove) fixed to the fixed plate 13. The slide rod 14 passes through the fixed plate 13, and its end is provided with a limiting plate 15 (limiting part). A first spring 16 is sleeved on the slide rod 14, and the first spring 16 abuts between the fixed plate 13 and the limiting plate 15. This makes an elastic connection formed between the lifting frame (U-shaped frame 12) and the main body of the heat insulation cover 19 (heat insulation cover 19, bottom frame 18, fixed plate 13, etc.).

[0026] The end of the robotic arm 8 is equipped with an adsorption component, which is used to connect with the docking part on the hoisting frame and drive it to rise and fall. The robotic arm 8 is used to grasp and move the insulation cover assembly. An electromagnet 9, serving as an adsorption component, is fixed to the end of the robotic arm 8. A metal plate 10, serving as a docking part, is fixed on the lifting frame (U-shaped frame 12), and the metal plate 10 has a docking hole 11. By inserting the electromagnet 9 into the docking hole 11 and energizing it, the robotic arm 8 can be quickly and accurately connected and released from the insulation cover assembly. The robotic arm 8 is mounted on an electric actuator 7. like Figure 4 and Figure 5 As shown, the gas regulation passage includes: An outer tube 20 is disposed at the top of the hoisting frame and an insertion tube 22 is coaxially disposed within the outer tube 20; An inner tube 23 is provided at the top of the heat insulation cover 19, the inner tube 23 extends upward and is slidably sleeved with the insertion tube 22; During the first period when the hoisting frame rises relative to the insulation cover 19, an exhaust gap is formed between the top end of the inner tube 23 and the insertion tube 22; during the second period of rising, the sealing component located at the bottom end of the insertion tube 22 moves downward and seals the bottom opening of the inner tube 23.

[0027] More specifically, the sealing component includes a sealing plate 28 connected to the bottom end of the insertion tube 22 via a telescopic hose, and a sealing plug 29 disposed at the bottom of the sealing plate 28.

[0028] Furthermore, the insertion tube 22 is provided with an impeller 31 driven by a motor 305.

[0029] In this embodiment, a gas regulation passage is provided between the lifting frame and the insulation cover 19. This passage mainly includes: an outer tube 20 fixed to the top of the lifting frame (U-shaped frame 12), and an insertion tube 22 coaxially fixed inside the outer tube 20 via a connecting block 21; an inner tube 23 fixed to the top of the insulation cover 19 (via an inner connecting frame 17 or similar structure), extending upwards and slidably engaging with the insertion tube 22. The bottom end of the insertion tube 22 is connected to a sealing component via a connecting rod 25 or similar components. This sealing component includes a sealing plate 28 and a sealing plug 29 fixed to its bottom. The sealing plate 28 is connected to the bottom end of the insertion tube 22 via a telescopic structure (or other form of telescopic hose) formed by a fixing rod 26 and a second spring 27. An inclined surface 24 is provided at the point where the inner tube 23 extends upwards and slidably engages with the insertion tube 22.

[0030] The working process of the gas regulation passage is as follows: When the robotic arm 8 drives the hoisting frame (U-shaped frame 12) to rise (first stage), and the main body of the insulation cover 19 is temporarily lagging behind due to gravity, the insertion pipe 22 rises with the hoisting frame, creating a gap between it and the inner pipe 23, allowing the high-temperature gas inside the insulation cover 19 to escape through this gap. As the hoisting frame continues to rise (second stage), the insertion pipe 22 drives the sealing plate 28 to move the sealing plug 29 upward, ultimately sealing the bottom opening of the inner pipe 23, thus closing the passage in the later stage of the rise (second stage) and preventing external cold air from flowing back from the top when the insulation cover 19 is subsequently raised. To further improve the exhaust efficiency, an impeller 31 driven by a motor 305 can be installed inside the insertion pipe 22 to actively extract and exhaust hot gas.

[0031] like Figures 6 to 8 As shown, an adaptive sealing component is provided at the bottom of the bottom frame 18. The adaptive sealing component is configured to: passively enhance the seal between the bottom frame 18 and the worktable surface when the heat insulation cover assembly descends to the movable worktable; and automatically reset when the heat insulation cover assembly rises.

[0032] Specifically, the adaptive sealing assembly includes: An air storage chamber 33 is provided at the bottom of the bottom frame 18, and a movable sealing strip 34 is provided inside the air storage chamber 33. The elastic sidewall is provided on the outside of the heat insulation cover 19; A linkage air passage connecting the gas storage chamber 33 and the elastic sidewall; When the heat insulation cover assembly is suspended, the elastic sidewall, under its own elastic force, drives the sealing strip 34 to extend downward through the linkage air passage; when the heat insulation cover assembly descends to the workbench, the sealing strip 34 is compressed and retracts, and the elastic sidewall is driven to deform inward through the linkage air passage to press the heat insulation cover 19. More specifically, the linkage air path includes a pipe 35 connecting to the top of the air storage chamber 33 and a telescopic push pipe 36 connected to the pipe 35. The bottom end of the telescopic push pipe 36 is provided with a push plate 37, and the push plate 37 is linked to the elastic sidewall through a sliding connection structure.

[0033] More specifically, the sliding connection structure includes a groove 38 formed on the push plate 37, and a sliding column 39 fixed to the top of the elastic sidewall and slidably inserted into the groove 38.

[0034] The working process of this adaptive sealing component is as follows: Suspended state: When the insulation cover assembly is suspended in the air by the robotic arm 8, the elastic strip 32 (elastic sidewall) tends to expand outward under its own elastic force. At this time, through the cooperation of the sliding column 39 and the sliding groove 38, the push plate 37 is pushed upward, which drives the telescopic push tube 36 to shorten, and the gas inside it is forced into the gas storage chamber 33 through the pipe 35, thereby pushing the sealing strip 34 downward, so that it protrudes slightly from the bottom surface of the bottom frame 18.

[0035] Descending and Sealing: When the insulation cover assembly descends onto the support plate 6 of the moving worktable, the protruding sealing strip 34 first contacts the support plate 6. As the bottom frame 18 continues to descend, the sealing strip 34 is pressed back into the air storage chamber 33, and the gas in the air storage chamber 33 is compressed and enters the telescopic push tube 36 through the pipe 35, causing it to extend. The telescopic push tube 36 pushes the push plate 37 downward, and through the cooperation of the sliding groove 38 and the sliding column 39, it bends and deforms the elastic strip 32 inward, making it tightly fit against the workpiece, thereby simultaneously achieving bottom sealing and side insulation.

[0036] Rising and Reset State: When the workpiece insulation ends and the robotic arm 8 lifts the insulation cover assembly, the bottom frame 18 moves away from the support plate 6, and the sealing strip 34 loses pressure. The elasticity of the elastic strip 32 is released again, pushing the push plate 37 upward to reset, causing the telescopic push tube 36 to shorten and drawing the gas back into the gas storage chamber 33. The sealing strip 34 retracts under the action of air pressure or its own structure, and the entire assembly returns to the suspended ready state. During this reset process, the elastic strip 32 changes from bent to stretched, increasing the internal volume of the insulation cover 19 and forming a slight negative pressure, which helps to further prevent residual hot gas from being ejected from the bottom.

[0037] The workflow is summarized as follows: Forging press 1 completes the forging of the workpiece.

[0038] External transfer equipment (such as a robot) places the high-temperature workpiece onto the support plate 6 of the mobile worktable.

[0039] The robotic arm 8 moves above the insulation cover assembly and uses the electromagnet 9 to attract and dock with the metal plate 10, thus grasping the insulation cover assembly.

[0040] The robotic arm 8 moves the insulation cover assembly above the workpiece and lowers it. During the descent, the adaptive sealing assembly is activated, the sealing strip 34 contacts the support plate 6 and retracts, triggering the elastic strip 32 to bend inward and press the insulation cover 19, thus achieving sealing and insulation.

[0041] The sliding plate 3 carries the workpiece and the heat preservation cover assembly covering it along the moving table 2 for long-distance transfer, during which the workpiece is kept in a heat preservation state.

[0042] Upon reaching the target workstation, the robotic arm 8 lifts the hoisting frame (U-shaped frame 12). During the initial lifting phase, the main body of the insulation cover 19 rises slowly due to the elastic lifting mechanism, and the gas regulation passage opens to expel the high-temperature gas inside. During the later stages of lifting, the gas regulation passage closes, the adaptive sealing component resets, and the elastic strip 32 unfolds.

[0043] The robotic arm 8 removes the insulation cover assembly, completing the workpiece transfer, and can proceed to the next cycle or enter the subsequent aging treatment process.

[0044] The above structure enables automated heat preservation and controllable venting during the transfer of forged workpieces, effectively solving the problems of low efficiency, high risk, and severe heat loss associated with manual wrapping. It is particularly suitable for the mass production of complex aluminum alloy forgings with multiple ribs.

[0045] In summary, the technical effects of implementing this technical solution are as follows: By combining the robotic arm 8, the electromagnet 9 adsorption assembly, and the insulation cover assembly, the entire process of insulation covering and transfer of workpieces after forging is fully automated. This completely replaces the original dangerous manual operation of wrapping insulation film in a high-temperature environment, completely eliminating the safety hazard of operators being burned. At the same time, the automated process significantly improves the work cycle and production efficiency, perfectly matching the rhythm requirements of large-scale, continuous production.

[0046] The device is capable of actively and enclosedly insulating the workpiece during transport. It effectively isolates the workpiece from the external low-temperature environment, greatly reducing heat loss of the forging during the critical transport stage, providing a stable temperature basis for subsequent heat preservation and aging treatment, thereby significantly improving the uniformity of the final forging structure and the stability of its mechanical properties.

[0047] A flexible lifting mechanism (slide bar 14, spring) achieves a flexible connection between the hoisting frame and the main body of the insulation cover 19, and a gas regulation passage (inner pipe 23, insertion pipe 22, sealing component) with initial venting and subsequent sealing functions is provided. During unloading, the main body of the insulation cover 19 rises with a delay due to gravity, providing a controllable path and time for the high-temperature gas inside, preventing hot gas from suddenly spraying out from the bottom as the cover rapidly rises. In the initial stage of rising, gas is discharged from the pre-set passage at the top, guiding the hot gas upwards and effectively protecting operators in the bottom working area from burns caused by the high-temperature gas. In the later stage of rising, the passage automatically seals to prevent the creation of negative pressure when the insulation cover 19 is raised, thus preventing the intake of a large amount of cold air from the top and avoiding localized rapid cooling of the workpiece.

[0048] The bottom of the base frame 18 is equipped with an adaptive sealing assembly consisting of an air storage chamber 33, a sealing strip 34, elastic sidewalls, and a linkage air passage. When the insulation cover 19 descends to the worktable, the sealing strip 34 is pressed, triggering the linkage mechanism to deform the elastic sidewalls inward, actively pressing the sides of the workpiece. At the same time, the sealing strip 34 itself also adheres tightly to the table surface, achieving a composite dynamic seal between the bottom and sides, with a insulation effect far superior to that of a static cover. During lifting, the assembly automatically resets under elastic action, and the expansion of the elastic sidewalls increases the space inside the cover, creating a slight negative pressure that further draws in residual hot air from the bottom and prevents it from overflowing, further enhancing operational safety.

[0049] The system organically integrates functions such as exhaust, sealing, heat preservation, and mechanical linkage through air circuits, mechanical structures, and elastic elements. The entire device is compact and highly efficient. Most actions are achieved through mechanical contact, air pressure changes, and the natural response of elastic elements, eliminating the need for complex sensors and drive controllers for each function. This improves system reliability and economy, and reduces manufacturing and maintenance costs.
