Description

Technical Field

[0001] The present application relates to the field of aerospace component forging, and in particular to an intelligent control method and device for a fully enclosed vacuum isothermal forging system. Background Art

[0002] Near-isothermal forging means heating the billet and the die to similar temperatures and forging at a lower strain rate.

[0003] Due to the advantages of near-isothermal forging, such as improving material properties, improving processing accuracy and surface quality, and being able to adapt to complex shapes and high strength requirements, current aerospace parts are often forged using near-isothermal forging.

[0004] In traditional near-isothermal forging, since the die cannot be heated to the same high temperature as the billet, the billet temperature drops quickly, which easily leads to the formation of coarse grains in the surface area of ​​the billet, resulting in the inability to achieve superplastic forming of the billet. Summary of the invention

[0005] The present application provides an intelligent control method and device for a fully enclosed vacuum isothermal forging system, which can improve the transfer efficiency when the billet is heated, thereby avoiding the problem of coarse grains being easily formed in the surface area due to the drop in billet temperature.

[0006] In the first aspect, the present application provides an intelligent control method for a fully enclosed vacuum isothermal forging system, which is applied to an intelligent control device of the fully enclosed vacuum isothermal forging system. The fully enclosed vacuum isothermal forging system also includes multiple heating furnaces in a vacuum environment and an intelligent robot that transfers billets in the multiple heating furnaces; a sliding gate is provided outside each heating furnace close to the side of the intelligent robot; the method includes: obtaining a target heating task for the target billet; the target heating task is used to indicate multiple steps in the heating process of the target billet, and each step is used to indicate a heating furnace for heating in the step; before the target billet is heated in the heating furnace of the current step until the end of the current step, the sliding gate of the target heating furnace for heating the next step of the current step is controlled to open according to the target heating task.

[0007] In the intelligent control method of the fully enclosed vacuum isothermal forging system provided in the present application, the intelligent control device can obtain the target heating task of the target billet, and the target heating task is used to indicate multiple steps in the heating process of the target billet, and each step is used to indicate the heating furnace for heating in the step. In this way, the intelligent control device can grasp the heating furnace for heating the target billet in each step, and the subsequent intelligent control device can control the opening of the sliding gate of the target heating furnace for heating in the next step of the current step before the target billet is heated in the heating furnace of the current step until the end of the current step. In this way, when the heating of the target billet is completed in the current step, when the intelligent robot transfers the target billet to the target heating furnace of the next step, there is no need to wait for the sliding gate of the target heating furnace to open, thereby shortening the waiting time for the transfer when the target billet is heated, thereby improving the transfer efficiency when the target billet is heated, avoiding the formation of coarse grains in the surface area due to the drop in billet temperature, and helping the target billet to achieve superplastic forming.

[0008] Optionally, the method further includes: before or after opening the sliding gate of the target heating furnace, controlling the target heating furnace to start heating.

[0009] In this way, the target heating furnace can heat the space inside the target heating furnace and the surrounding space outside the target heating furnace in advance before the intelligent robot transfers the target blank, thereby avoiding a sharp drop in temperature of the target blank when it is transferred to the target heating furnace, and avoiding the formation of coarse grains in the surface area due to the drop in blank temperature.

[0010] Optionally, before the target blank of the target heating task is heated in the heating furnace of the current step to the end of the current step, the sliding gate of the target heating furnace for heating in the next step of the current step is controlled to be opened according to the target heating task, including: when the target blank is heated to a first temperature in the heating furnace of the current step, the sliding gate of the target heating furnace is opened to a first opening; the first temperature is lower than the heating temperature required for the current step; the first opening is smaller than the maximum opening of the sliding gate; when the target blank is heated to a second temperature in the heating furnace of the current step, the sliding gate of the target heating furnace is opened to a second opening; the second temperature is higher than the first temperature and lower than the heating temperature required for the current step; the second opening is larger than the first opening.

[0014] In the intelligent control method of the fully enclosed vacuum isothermal forging system provided in the present application, the intelligent control device can control the target heating furnace to stop heating based on the decrease in the vacuum degree of the vacuum environment when controlling the target heating furnace to heat in advance. The decrease in the vacuum degree of the vacuum environment may be due to a leak in the vacuum environment. At this time, stopping the heating of the target heating furnace in advance can avoid aggravating the leakage caused by heating the vacuum environment.

[0015] Optionally, the method further includes: acquiring heating tasks for a plurality of candidate blanks; selecting, from the plurality of candidate blanks, a candidate blank whose heating task includes a plurality of working steps and whose heating furnaces indicated by the plurality of working steps for heating include a plurality of heating furnaces as the target blank.

The processing module is used to control the opening of a sliding gate of a target heating furnace for heating in the next step of the current step according to the target heating task before the target billet is heated in the heating furnace of the current step until the end of the current step.

[0017] Optionally, the processing module is further used to control the target heating furnace to start heating before or after opening the sliding gate of the target heating furnace.

[0018] Optionally, the processing module is specifically used to open the sliding gate of the target heating furnace to a first opening when the target blank is heated to a first temperature in the heating furnace of the current step; the first temperature is lower than the heating temperature required for the current step; the first opening is smaller than the maximum opening of the sliding gate; when the target blank is heated to a second temperature in the heating furnace of the current step, the sliding gate of the target heating furnace is opened to a second opening; the second temperature is higher than the first temperature and lower than the heating temperature required for the current step; the second opening is larger than the first opening.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] It should be noted that, in the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0030] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0031] Near-isothermal forging means heating the billet and the die to similar temperatures and forging at a lower strain rate.

[0032] Due to the advantages of near-isothermal forging, such as improving material properties, improving processing accuracy and surface quality, and being able to adapt to complex shapes and high strength requirements, current aerospace parts are often forged using near-isothermal forging.

[0033] In traditional near-isothermal forging, since the die cannot be heated to the same high temperature as the billet, the billet temperature drops quickly, which easily leads to the formation of coarse grains in the surface area of ​​the billet, resulting in the inability to achieve superplastic forming of the billet.

[0034] Based on this, the embodiment of the present application provides an intelligent control method and device for a fully enclosed vacuum isothermal forging system, which can heat the mold to the same high temperature as the billet and improve the transfer efficiency when the billet is heated, thereby avoiding the formation of coarse grains in the surface area due to the drop in billet temperature, thereby solving the problem of achieving superplastic forming of the billet and the mold under isothermal conditions.

[0035] The following is an introduction with reference to the accompanying drawings.

[0036] Figure 1 This is a schematic diagram of the top view of the fully enclosed vacuum isothermal forging system provided in the embodiment of the present application. Figure 1 As shown, the fully enclosed vacuum isothermal forging system may include: a billet vacuum heating unit 100 , a billet vacuum forging unit 200 , a vacuum pumping unit 300 , and an intelligent control device 400 .

[0037] The vacuum heating unit 100 includes a vacuum tunnel 11. A plurality of heating furnaces 12 ( Figure 1 In the figure, three heating furnaces on each side, namely, heating furnace No. 1 1, heating furnace No. 2, heating furnace No. 3, heating furnace No. 4, heating furnace No. 5, and heating furnace No. 6, are shown as examples). A material rack 14 for placing blanks 13 is provided in each heating furnace 12.

[0038] Each heating furnace 12 may be provided with a heating device ( Figure 1 (not shown in the figure), the heating device can be used to heat the blank 13 placed in the material rack 14.

[0039] In some embodiments, the heating device in the heating furnace 12 may have a communication connection (eg, a wired connection or a wireless connection) with the intelligent control device 400, and the heating device may receive a driving signal from the intelligent control device 400, thereby driving the heating device to start heating or end heating.

[0040] A track 15 is laid along the entire length of the vacuum tunnel 11 , and an intelligent robot 16 for clamping the blank 13 is placed on the track 15 . The intelligent robot 16 can slide back and forth along the track 15 .

[0041] Each heating furnace 12 is provided with a sliding gate 17 that can be opened and closed on the side wall of the vacuum tunnel 11 (or the side close to the intelligent robot 16 ).

[0042] In some embodiments, the sliding gate 17 may be provided with a driving device ( Figure 1 The driving device may have a communication connection (e.g., a wired connection or a wireless connection) with the intelligent control device 400, and the driving device may be used to receive a driving signal from the intelligent control device 400, thereby driving the sliding gate 17 to open (e.g., open to a certain degree or fully open) or close.

[0043] As an example, the driving device may include a reduction device and a driving motor, the driving device includes a driving gear and a driven rack, and an output gear is provided on the output shaft of the driving motor. The driving gear of the driving device meshes with the output gear of the driving motor, the driven rack is fixed on the sliding gate 17, and the driving gear meshes with the driven rack. The driving motor can be used to receive a driving signal from the intelligent control device 400, and rotate forward or reverse according to the driving signal, thereby driving the sliding gate 17 to open or close through the driving device.

[0044] Each heating furnace 12 is also provided with an openable furnace door 12a on the outside (or the side away from the intelligent robot 16). When loading materials, the staff can place the blanks 13 from the outside on the material rack 14 of each heating furnace 12 through the furnace door 12a.

[0045] The blank vacuum forging unit 200 may include a forging machine 21 , a vacuum forging chamber 22 , and a connecting gate 23 .

[0046] After the blank 13 is heated in the heating furnace 12 , it can be taken out from the heating furnace 12 by the intelligent robot 16 and clamped to the connecting gate 23 . The intelligent robot 16 can open the connecting gate 23 , load the blank 13 into the mold in the vacuum forging chamber 22 , and then forge it by the forging press 21 .

[0047] In some embodiments, a heating device may be further provided in the vacuum forging chamber 22 , and the heating device may heat the mold in the vacuum forging chamber 22 , and the heating temperature of the mold is the same as the heating temperature of the blank 13 .

[0048] The vacuum unit 300 may include a Roots pump and a diffusion pump, and is respectively connected to each heating furnace 12 , the vacuum tunnel 11 and the vacuum forging chamber 22 through vacuum pipes.

[0049] The vacuum unit 300 can be used to vacuum each heating furnace 12, vacuum tunnel 11 and vacuum forging chamber 22. In this case, after the vacuum unit 300 vacuums each heating furnace 12 and vacuum tunnel 11, each heating furnace 12 can also be understood to be in a vacuum environment. The opening and closing of the sliding gate 17 will not break the vacuum of the heating furnace 12, and the opening of the furnace door 12a will break the vacuum of the heating furnace 12. Therefore, after the heating furnace 12 and the vacuum tunnel 11 are vacuumed, if the furnace door 12a of a heating furnace 12 needs to be opened for loading or unloading, the sliding gate 17 needs to be closed first to prevent the vacuum tunnel 11 and other heating furnaces 12 from breaking the vacuum.

[0050] In some embodiments, the vacuum unit 300 may further include a vacuum sensor, which may be used to measure the vacuum degree at each heating furnace 12 , vacuum tunnel 11 , and vacuum forging chamber 22 .

[0051] The intelligent control device 400 can be used to automatically control all operations of the vacuum heating unit 100, the billet vacuum forging unit 200, and the vacuum unit 300, and drive the heating device in the heating furnace 12 or the sliding gate 17 outside the heating furnace 12 to implement the intelligent control method of the fully enclosed vacuum isothermal forging system provided in the embodiment of the present application. The specific process can be referred to as described in the following embodiments and will not be repeated here.

[0052] The execution subject of the intelligent control method of the fully enclosed vacuum isothermal forging system provided in the embodiment of the present application is an intelligent control device (such as the above-mentioned intelligent control device 400). Optionally, the execution subject of the intelligent control method of the fully enclosed vacuum isothermal forging system may also be a processor (such as a central processing unit (CPU)) in the aforementioned intelligent control device; or, the execution subject may also be a software system installed in the aforementioned intelligent control device for executing the intelligent control method; or, the execution subject may also be a functional module in the aforementioned intelligent control device for executing the intelligent control method, etc. The embodiment of the present application does not limit this.

[0053] For the sake of simplicity, the following is an introduction using the intelligent control method for a fully enclosed vacuum isothermal forging system provided in an embodiment of the present application as an example in which the executing body is an intelligent control device.

[0054] Figure 2 The figure is a flow chart of the intelligent control method of the fully enclosed vacuum isothermal forging system provided in the embodiment of the present application. Figure 2 As shown, the method includes the following steps: S101, obtaining a target heating task for a target blank.

[0055] The target heating task is used to indicate multiple steps in the target blank heating process, and each step is used to indicate a heating furnace for heating in the step.

[0056] In a possible implementation, the intelligent control device may include an input / output interface, which may include a mouse, a keyboard, or a touch screen, etc. The intelligent control device may receive a heating task of a target blank input by a worker through the input / output interface.

[0057] In another possible implementation, the intelligent control device may also be connected to other devices or platforms for communication, and the intelligent control device may receive a heating task for the target blank sent from other devices or platforms.

[0058] S102, before the target blank is heated in the heating furnace of the current step until the current step ends, control the opening of the sliding gate of the target heating furnace for heating in the next step of the current step according to the target heating task.

[0059] Optionally, before the target blank is heated in the heating furnace of the current step until the end of the current step, the intelligent control device can determine the target heating furnace for heating in the next step of the current step according to the target heating task, and then control the opening of the sliding gate of the target heating furnace.

[0060] As an example, each heating furnace may be provided with a temperature measuring device (for example, the temperature measuring device may be a thermometer provided on the material rack 14) to measure the temperature of the blank, and the intelligent control device may be connected to the temperature measuring device for communication, and obtain the temperature of the blank in the heating furnace through the temperature measuring device. Each step in the target heating task is also used to indicate the heating temperature of the step (to be heated to). In this case, the intelligent control device may determine whether the heating of the target blank is completed in the current step according to the temperature of the target blank, and when the target blank is heated to the target temperature, control the opening of the sliding gate of the target heating furnace for heating in the next step of the current step.

[0061] The target temperature is lower than the heating temperature of the current step (to be heated to), and the difference between the target temperature and the heating temperature of the current step (to be heated to) is equal to the preset temperature difference. The preset temperature difference can be preset in the intelligent control device. For example, the preset temperature difference can be set to 30°C, 40°C, 50°C, or 60°C. The specific value of the preset temperature difference is not limited in the embodiment of the present application.

[0062] For example, taking the heating temperature of the target blank in the current process step (needs to be heated to) as 800°C, assuming the preset difference is 50°C, then when the target blank is heated to 750°C in the current process step, the intelligent control device can control the opening of the sliding gate of the target heating furnace for heating in the next process step of the current process step.

[0063] As another example, each heating furnace may be provided with a blank detection device (for example, the blank detection device may be a gravity sensor provided on the material rack 14) to detect whether a blank is placed in the heating furnace, and the intelligent control device may be connected to the blank detection device for communication, and sense whether a blank is placed in the heating furnace through the blank detection device. Each work step in the target heating task is also used to indicate the heating duration of the work step (requiring heating). In this case, the intelligent control device may determine the actual heating duration of the target blank in the current work step based on the time when the target blank begins to be placed in the heating furnace and the current time, thereby determining whether the heating of the target blank is completed in the current work step, and when the actual heating duration of the target blank in the current work step reaches the target duration, control the opening of the sliding gate of the target heating furnace for heating in the next work step of the current work step.

[0064] The target duration is less than the heating duration of the current step (requiring heating), and the difference between the target duration and the heating duration of the current step (requiring heating) is equal to the preset duration difference. The preset duration difference can be preset in the intelligent control device, for example, the preset duration difference can be set to 10 minutes, 8 minutes, 5 minutes, or 3 minutes. The specific value of the preset duration difference is not limited in the embodiment of the present application.

[0065] For example, taking the heating time of the current process step (requiring heating) of the target blank as 30 minutes, assuming that the preset time difference is 3 minutes, when the current process step of the target blank is heated to 27 minutes, the intelligent control device can control the opening of the sliding gate of the target heating furnace for heating the next process step of the current process step.

[0066] In the intelligent control method of the fully enclosed vacuum isothermal forging system provided in the embodiment of the present application, the intelligent control device can obtain the target heating task of the target billet, and the target heating task is used to indicate multiple steps in the heating process of the target billet, and each step is used to indicate the heating furnace for heating in the step. In this way, the intelligent control device can grasp the heating furnace for heating the target billet in each step, and the subsequent intelligent control device can control the opening of the sliding gate of the target heating furnace for heating in the next step of the current step before the target billet is heated in the heating furnace of the current step until the end of the current step. In this way, when the heating of the target billet is completed in the current step, the intelligent robot does not need to wait for the sliding gate of the target heating furnace to open when transferring the target billet to the target heating furnace of the next step, thereby shortening the waiting time for the transfer when the target billet is heated, thereby improving the transfer efficiency when the target billet is heated, avoiding the formation of coarse grains in the surface area due to the drop in billet temperature, and helping the target billet to achieve superplastic forming.

[0067] In some possible embodiments, before or after the sliding gate of the target heating furnace is opened, the intelligent control device may also start heating the target heating furnace.

[0068] In this way, the target heating furnace can heat the space inside the target heating furnace and the surrounding space outside the target heating furnace in advance before the intelligent robot transfers the target blank, thereby avoiding a sharp drop in temperature of the target blank when it is transferred to the target heating furnace, and avoiding the formation of coarse grains in the surface area due to the drop in blank temperature.

[0069] In some embodiments, heating the vacuum environment may cause the material of the vacuum environment (such as the above-mentioned vacuum tunnel 11) to expand, resulting in poor sealing performance, which may affect the vacuum degree of the vacuum environment. Therefore, when the target heating furnace starts heating in advance, the intelligent control device can control the heating rate of the target heating furnace to the surrounding vacuum environment by controlling the opening of the sliding gate. In this case, the above-mentioned S102 may specifically include the following steps: Step 1a: when the target blank is heated to a first temperature in the heating furnace of the current process step, the sliding gate of the target heating furnace is opened to a first opening degree.

[0070] The first temperature is lower than the heating temperature required for the current process step, and the first opening is smaller than the maximum opening of the sliding gate.

[0071] Step 2a: when the target blank is heated to a second temperature in the heating furnace of the current process step, the sliding gate of the target heating furnace is opened to a second opening degree.

[0072] The second temperature is higher than the first temperature and lower than the heating temperature required for the current process step, and the second opening is greater than the first opening.

[0073] Optionally, the second opening degree may be the maximum opening degree of the sliding gate, or in other words, the second opening degree may be 100%.

[0074] For example, taking the heating temperature of the target blank in the current step (needs to be heated to) as 800°C as an example, assuming that the first temperature is 700°C, the first opening is 50%, the second temperature is 750°C, and the second opening is 100%, the intelligent control device can open the sliding gate of the target heating furnace in the next step to an opening of 50% when the target blank is heated to 700°C in the heating furnace of the current step, and open the sliding gate of the target heating furnace in the next step to an opening of 100% when the target blank is heated to 750°C in the heating furnace of the current step.

[0075] In some other possible embodiments, as described above, the heating progress of the target blank in the current process step can also be represented by the heating duration. The intelligent control device can also control the opening of the sliding gate according to the heating duration, thereby controlling the heating rate of the target heating furnace to the surrounding vacuum environment. In this case, the above S102 can also specifically include the following steps: Step 1b: when the heating time of the target blank in the heating furnace of the current step reaches a first time, the sliding gate of the target heating furnace is opened to a first opening degree.

[0076] The first duration is shorter than the heating duration required for the current working step, and the first opening is smaller than the maximum opening of the sliding gate.

[0077] Step 2b: when the heating time of the target blank in the heating furnace of the current step reaches a second time, the sliding gate of the target heating furnace is opened to a second opening degree.

[0078] The second time duration is longer than the first time duration, and the second time duration is shorter than the heating time duration required for the current step, and the second opening degree is greater than the first opening degree.

[0079] For example, taking the heating time of the current step (requiring heating) of the target blank as 30 minutes, assuming that the first time is 25 minutes, the first opening is 50%, the second time is 28 minutes, and the second opening is 100%, the intelligent control device can open the sliding gate of the target heating furnace of the next step to 50% opening when the heating furnace of the current step of the target blank is heated to 25 minutes, and open the sliding gate of the target heating furnace of the next step to 100% opening when the target blank is heated in the heating furnace of the current step to 28 minutes.

[0080] In the intelligent control method of a fully enclosed vacuum isothermal forging system provided in an embodiment of the present application, the intelligent control device can control the opening of the sliding gate of the target heating furnace by different heating temperatures or different heating times when controlling the target heating furnace to heat in advance. The larger the opening of the sliding gate, the greater the heating rate of the target heating furnace to the surrounding vacuum environment. Therefore, the heating rate of the target heating furnace to the surrounding vacuum environment can be controlled by controlling the opening of the sliding gate, thereby avoiding the deterioration of the sealing due to the expansion of the material in the vacuum environment (such as the above-mentioned vacuum tunnel 11) caused by too fast a heating rate, thereby avoiding affecting the vacuum degree of the vacuum environment.

[0081] In some possible embodiments, as described above, the vacuum unit 300 may further include a vacuum sensor, which may be used to measure the vacuum degree of the vacuum environment (each heating furnace 12, vacuum tunnel 11 and vacuum forging chamber 22), and the intelligent control device may also control the target heating furnace to stop heating or continue heating based on the influence of the heating of the target heating furnace on the vacuum degree of the vacuum environment in advance. In this case, the method may further include the following steps: Step 1c: Based on the decrease in the vacuum degree of the vacuum environment, the target heating furnace is controlled to stop heating.

[0082] For example, the intelligent control device may be preset with a vacuum degree drop value threshold value. When the vacuum degree drop value of the vacuum environment reaches the vacuum degree drop value threshold value, the intelligent control device may control the target heating furnace to stop heating.

[0083] The vacuum degree drop value threshold value may be set to 5%, 10% or 15% of the normal vacuum degree, etc. The embodiment of the present application does not limit the specific value of the vacuum degree drop value threshold value.

[0084] For example, taking the normal vacuum degree in the vacuum environment as 0.04mba, and assuming that the vacuum degree drop threshold is 10% of the normal vacuum degree, when the vacuum degree in the vacuum environment drops by 0.004mba, the intelligent control device can control the target heating furnace to stop heating.

[0085] Optionally, the control device may also control the target heating furnace to continue heating based on the fact that the vacuum degree of the vacuum environment has not decreased. The intelligent control device may control the target heating furnace to continue heating.

[0086] In the intelligent control method of the fully enclosed vacuum isothermal forging system provided in the embodiment of the present application, the intelligent control device can control the target heating furnace to stop heating based on the decrease in the vacuum degree of the vacuum environment when controlling the target heating furnace to heat in advance. The decrease in the vacuum degree of the vacuum environment may be due to a leak in the vacuum environment. At this time, stopping the heating of the target heating furnace in advance can avoid aggravating the leakage caused by heating the vacuum environment.
