[0003] Due to the advantages of improving material performance, improving machining precision and surface quality, and being able to adapt to complex shapes and high strength requirements, current aerospace parts are often forged by using near-isothermal forging.

[0004] Traditional near-isothermal forging cannot heat the die to the same high temperature as the blank, and the temperature of the blank drops quickly, which easily forms coarse grains in the surface layer of the blank, resulting in that the blank cannot be superplastic formed. SUMMARY

[0005] The present application provides an intelligent control method and device of a fully-closed vacuum isothermal forging system, which can improve the transfer efficiency when the blank is heated, thereby avoiding the problem that the temperature drop of the blank easily forms coarse grains in the surface layer.

[0006] In a first aspect, the present application provides an intelligent control method of a fully-closed vacuum isothermal forging system, which is applied to an intelligent control device of the fully-closed vacuum isothermal forging system. The fully-closed vacuum isothermal forging system further includes a plurality of heating furnaces in a vacuum environment and an intelligent robot for transferring a blank in the plurality of heating furnaces. A sliding gate is arranged on each heating furnace close to the side of the intelligent robot. The method includes: obtaining a target heating task of a target blank; the target heating task is used to indicate a plurality of working steps in the target blank heating process, and each working step is used to indicate a heating furnace for heating in the working step; before the target blank is heated in the heating furnace of the current working step to the end of the current working step, the sliding gate of the target heating furnace for heating in the next working step of the current working step is controlled to be opened according to the target heating task.

[0007] The intelligent control method of the full-closed vacuum isothermal forging system provided in the application, the intelligent control device can obtain a target heating task of a target blank, the target heating task is used to indicate a plurality of working steps in a target blank heating process, and each working step is used to indicate a heating furnace for heating in the working step. In this way, the intelligent control device can master the heating furnace for heating the target blank in each working step. The intelligent control device can control the sliding door of the target heating furnace for heating in the next working step of the current working step to be opened before the target blank is heated to the end of the current working step in the heating furnace of the current working step. In this way, when the target blank is heated in the current working step and the intelligent robot transfers the target blank to the target heating furnace of the next working step, the sliding door of the target heating furnace does not need to be opened, so that the waiting time for transferring the target blank during heating is shortened, the transfer efficiency during heating of the target blank is improved, the coarse grains are less likely to be formed in the surface layer area due to the temperature drop of the blank, and the target blank is more likely to be superplastically formed.

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

[0009] In this way, the target heating furnace can heat the space in the target heating furnace and the surrounding space outside the target heating furnace in advance before the intelligent robot transfers the target blank, so that the temperature of the target blank is less likely to drop sharply when the target blank is transferred to the target heating furnace, and the coarse grains are less likely to be formed in the surface layer area due to the temperature drop of the blank.

[0010] Optionally, the sliding door of the target heating furnace for heating in the next working step of the current working step is opened according to the target heating task before the target blank is heated to the end of the current working step in the heating furnace of the current working step, and the method includes: in the case that the target blank is heated to a first temperature in the heating furnace of the current working step, the sliding door of the target heating furnace is opened to a first opening degree; the first temperature is lower than the heating temperature required by the current working step; the first opening degree is less than the maximum opening degree of the sliding door; in the case that the target blank is heated to a second temperature in the heating furnace of the current working step, the sliding door of the target heating furnace is opened to a second opening degree; the second temperature is higher than the first temperature and lower than the heating temperature required by the current working step; and the second opening degree is greater than the first opening degree.

[0011] In the intelligent control method of the fully-closed vacuum isothermal forging system, the intelligent control device can control the opening degree of the sliding gate of the target heating furnace by different heating temperatures or different heating durations when the target heating furnace is controlled to heat in advance, and the greater the opening degree of the sliding gate, the greater the heating rate of the target heating furnace to the surrounding vacuum environment, so that the heating rate of the target heating furnace to the surrounding vacuum environment can be controlled by controlling the opening degree of the sliding gate, thereby avoiding the poor sealing caused by the expansion of the material in the vacuum environment due to the too fast heating rate, and avoiding the influence on the vacuum degree of the vacuum environment.

[0012] Optionally, the second opening degree is the maximum opening degree of the sliding gate.

[0013] Optionally, the method further comprises: controlling the target heating furnace to stop heating based on the decrease of the vacuum degree of the vacuum environment.

[0014] In the intelligent control method of the fully-closed vacuum isothermal forging system, the intelligent control device can control the target heating furnace to stop heating based on the decrease of the vacuum degree of the vacuum environment when the target heating furnace is controlled to heat in advance. The decrease of the vacuum degree of the vacuum environment may be that the vacuum environment has a leakage, and stopping heating the target heating furnace in advance can avoid the leakage from being aggravated by heating the vacuum environment.

[0015] Optionally, the method further comprises: obtaining heating tasks of a plurality of candidate billets; and selecting a candidate billet whose heating task includes a plurality of working steps and whose heating furnace including a plurality of heating furnaces to be heated is the target billet from the plurality of candidate billets.

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort fall within the scope of the present application.

In fact, the words such as "exemplarily" or "for example" are intended to present the relevant concept in a specific manner.

[0033] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with basically the same function and effect. Those skilled in the art can understand that the words "first", "second" and the like are not used to limit the quantity and execution order.

[0034] Near-isothermal forging refers to heating the blank and the die to a similar temperature and performing forging at a low strain rate.

[0035] Due to the advantages of improving material performance, improving machining precision and surface quality, and being able to adapt to complex shape and high strength requirements, the current aerospace parts often adopt the way of near isothermal forging.

[0036] The traditional near isothermal forging cannot heat the die to the same high temperature as the blank, the temperature of the blank drops quickly, and coarse grains are easily formed in the surface layer region of the blank, which leads to the blank cannot realize superplastic forming.

[0037] Based on this, the embodiment of the application provides an intelligent control method and device for a fully-closed vacuum isothermal forging system, which can heat the die to the same high temperature as the blank, improve the transfer efficiency during blank heating, avoid the temperature drop of the blank leading to the formation of coarse grains in the surface layer region, and solve the problem of realizing superplastic forming of the blank and the die under isothermal conditions.

[0038] The following will be introduced in conjunction with the drawings.

[0039] Figure 1 The fully-closed vacuum isothermal forging system provided by the embodiment of the application provides a component schematic diagram in the overhead direction. As shown in the figure, Figure 1 The fully-closed vacuum isothermal forging system can include a blank vacuum heating unit 100, a blank vacuum forging unit 200, a vacuum pumping unit 300, and an intelligent control device 400.

[0040] The vacuum heating unit 100 includes a vacuum tunnel 11. On each side of the length direction of the vacuum tunnel 11, a plurality of heating furnaces 12 can be installed (for example, one heating furnace 1, two heating furnaces 2, three heating furnaces 3, four heating furnaces 4, five heating furnaces 5, and six heating furnaces 6 are shown on each side). Figure 1 Each heating furnace 12 is provided with a rack 14 for placing a blank 13.

[0041] Each heating furnace 12 can be provided with a heating device (not shown in the figure), which can be used to heat the blank 13 placed in the rack 14. Figure 1

[0042] In some embodiments, the heating device in the heating furnace 12 can have a communication connection (such as wired connection or wireless connection) with the intelligent control device 400, and the heating device can receive a driving signal from the intelligent control device 400, so as to drive the heating device to start heating or end heating.

[0043] A track 15 is laid along the entire length direction in 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.

[0044] ​Each heating furnace 12 is provided with a sliding gate 17 which can be opened and closed on the outer side of the vacuum tunnel 11 (or the side close to the intelligent robot 16).

[0045] In some embodiments, the sliding gate 17 can be provided with a driving device (not shown). Figure 1 The driving device can be in communication connection (for example, wired connection or wireless connection) with the intelligent control device 400, and can be used to receive driving signals from the intelligent control device 400, so as to drive the sliding gate 17 to open (for example, open to a certain degree or completely open) or close.

[0046] As an example, the driving device can include a reduction device and a driving motor, and the driving device includes a driving gear and a driven rack, and the output shaft of the driving motor is provided with an output gear. The driving gear of the driving device is engaged with the output gear of the driving motor, and the driven rack is fixed on the sliding gate 17, and the driving gear is engaged with the driven rack. The driving motor can be used to receive driving signals from the intelligent control device 400, and rotate forward or reverse according to the driving signals, so as to drive the sliding gate 17 to open or close through the driving device.

[0047] The outer side (or the side away from the intelligent robot 16) of each heating furnace 12 is also provided with an openable furnace door 12a. When feeding, the worker can place the blank 13 from the outside on the rack 14 of each heating furnace 12 through the furnace door 12a.

[0048] The blank vacuum forging unit 200 can include a forging press 21, a vacuum forging chamber 22, and a connecting gate 23.

[0049] After the blank 13 is heated in the heating furnace 12, it can be taken out of 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 perform forging by the forging press 21.

[0050] In some embodiments, the vacuum forging chamber 22 can also be provided with a heating device, which can heat the mold in the vacuum forging chamber 22. The mold heating temperature is the same as the heating temperature of the blank 13.

[0051] The vacuum pumping unit 300 can include a Roots pump and a diffusion pump, and is connected to each heating furnace 12, the vacuum tunnel 11 and the vacuum forging chamber 22 through a vacuum pipeline respectively.

[0052] The vacuum pumping unit 300 can be used to pump vacuum for each heating furnace 12, the vacuum tunnel 11 and the vacuum forging chamber 22. In this case, after the vacuum pumping unit 300 pumps vacuum for each heating furnace 12 and the vacuum tunnel 11, each heating furnace 12 can also be understood as being 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, so after pumping vacuum for the heating furnace 12 and the vacuum tunnel 11, if it is necessary to open the furnace door 12a of a certain heating furnace 12 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 vacuum.

[0053] In some embodiments, the vacuum pumping unit 300 can also include a vacuum sensor, which can be used to measure the vacuum degree at each heating furnace 12, the vacuum tunnel 11 and the vacuum forging chamber 22.

[0054] The intelligent control device 400 can be used to automatically control all operations of the vacuum heating unit 100, the blank vacuum forging unit 200 and the vacuum pumping unit 300, and drive the heating device in the heating furnace 12 or the sliding gate 17 outside the heating furnace 12 to realize the intelligent control method of the fully-closed vacuum isothermal forging system provided by the embodiments of the present application. The specific process can be referred to in the following embodiments, which will not be described here.

[0055] The execution subject of the intelligent control method of the fully-closed vacuum isothermal forging system provided by the embodiments of the present application is an intelligent control device (for example, the intelligent control device 400 described above). Alternatively, the execution subject of the intelligent control method of the fully-closed vacuum isothermal forging system can also be a processor (for example, a central processing unit (CPU)) in the foregoing intelligent control device; or the execution subject can also be a software system installed in the foregoing intelligent control device for executing the intelligent control method; or the execution subject can also be a functional module in the foregoing intelligent control device for executing the intelligent control method. The embodiments of the present application do not make any limitation in this regard.

[0056] For the sake of simplicity, the execution subject of the intelligent control method of the fully-closed vacuum isothermal forging system provided by the embodiments of the present application is taken as an intelligent control device for introduction in the following.

[0057] Figure 2 The flowchart of the intelligent control method of the fully-closed vacuum isothermal forging system provided by the embodiments of the present application is shown in FIG. 6. As shown in FIG. 6, the method includes the following steps: Figure 2

[0058] S101, obtaining a target heating task of a target blank.

[0059] ​The target heating task is used to indicate a plurality of steps in the target blank heating process, and each step is used to indicate a heating furnace for heating in the step.

[0060] In a possible implementation, the intelligent control device can include an input / output interface, which can include a mouse, a keyboard, or a touch display screen, etc. The intelligent control device can receive the target blank heating task input by the worker through the input / output interface.

[0061] In another possible implementation, the intelligent control device can also be connected with other devices or platforms, and the intelligent control device can receive the target blank heating task sent by the other devices or platforms.

[0062] S102, before the target blank is heated to the end of the current step in the heating furnace of the current step, the intelligent control device controls to open the sliding door of the target heating furnace of the next step of the current step according to the target heating task.

[0063] Optionally, before the target blank is heated to the end of the current step in the heating furnace of the current step, the intelligent control device can determine the target heating furnace of the next step of the current step according to the target heating task, and then controls to open the sliding door of the target heating furnace.

[0064] As an example, a temperature measuring device (for example, the temperature measuring device can be a thermometer arranged on the above-mentioned rack 14) can be arranged in each heating furnace to measure the temperature of the blank, and the intelligent control device can be connected with the temperature measuring device 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 (that needs to be heated to) of the step. In this case, the intelligent control device can determine whether the target blank is heated to the end in the current step according to the temperature of the target blank, and controls to open the sliding door of the target heating furnace of the next step of the current step when the target blank is heated to the target temperature.

[0065] The target temperature is less than the heating temperature (that needs to be heated to) of the current step, and the difference between the target temperature and the heating temperature (that needs to be heated to) of the current step is equal to a 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℃, 40℃, 50℃, or 60℃, etc. The specific value of the preset temperature difference is not limited in the embodiments of the present application.

[0066] Exemplarily, taking 800℃ as the heating temperature of the current working step of the target blank (which needs to be heated to), and taking 50℃ as the preset difference value, the intelligent control device can control to open the sliding door of the target heating furnace which is used to heat the next working step of the current working step, in the case that the target blank is heated to 750℃ in the current working step.

[0067] As another example, a blank detection device (for example, the blank detection device can be a gravity sensor arranged on the above-mentioned rack 14) can be arranged in each heating furnace to detect whether the blank is placed in the heating furnace. The intelligent control device can be in communication connection with the blank detection device, and can perceive whether the blank is placed in the heating furnace through the blank detection device. Each working step in the target heating task is also used to indicate the heating duration of the working step (which needs to be heated). In this case, the intelligent control device can determine the actual heating duration of the target blank in the current working step according to the time when the target blank starts to be placed in the heating furnace and the current time, so as to determine whether the heating of the target blank in the current working step is ended, and control to open the sliding door of the target heating furnace which is used to heat the next working step of the current working step, in the case that the actual heating duration of the target blank in the current working step reaches the target duration.

[0068] The target duration is less than the heating duration of the current working step (which needs to be heated), and the difference between the target duration and the heating duration of the current working step (which needs to be heated) is equal to the preset duration difference value. The preset duration difference value can be preset in the intelligent control device, for example, the preset duration difference value can be set to 10 minutes, 8 minutes, 5 minutes, or 3 minutes, etc. The specific value of the preset duration difference value is not limited in the embodiments of the present application.

[0069] Exemplarily, taking 30 minutes as the heating duration of the current working step of the target blank (which needs to be heated) as an example, and taking 3 minutes as the preset duration difference value, the intelligent control device can control to open the sliding door of the target heating furnace which is used to heat the next working step of the current working step, in the case that the target blank is heated to 27 minutes in the current working step.

[0070] In the intelligent control method of the fully-closed vacuum isothermal forging system provided by the embodiments of the present application, the intelligent control device can obtain a target heating task of a target blank, and the target heating task is used to indicate a plurality of working steps in a target blank heating process, and each working step is used to indicate a heating furnace for heating in the working step. In this way, the intelligent control device can master the heating furnace for heating the target blank in each working step, and the intelligent control device can control the sliding door of the target heating furnace for heating in the next working step to be opened before the target blank is heated to the end of the current working step in the heating furnace of the current working step. In this way, when the target blank is heated to the end of the current working step, the intelligent robot does not need to wait for the sliding door of the target heating furnace to be opened when the target blank is transferred to the target heating furnace of the next working step, so that the waiting time for transferring the target blank during heating is shortened, the transfer efficiency during heating of the target blank is improved, and the formation of coarse grains in the surface layer region caused by the temperature drop of the blank is avoided, which is helpful for the superplastic forming of the target blank.

[0071] In some possible embodiments, before or after the sliding door of the target heating furnace is opened, the intelligent control device can also start heating of the target heating furnace.

[0072] In this way, the target heating furnace can heat the space in the target heating furnace and the surrounding space outside the target heating furnace in advance before the target blank is transferred by the intelligent robot, so that the temperature of the target blank can be prevented from being greatly reduced when the target blank is transferred to the target heating furnace, and the formation of coarse grains in the surface layer region caused by the temperature drop of the blank can be avoided.

[0073] In some embodiments, heating in a vacuum environment can cause the material of the vacuum environment (for example, the vacuum tunnel 11) to expand, which can cause poor sealing and 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 on the surrounding vacuum environment by controlling the opening degree of the sliding door. In this case, S102 can specifically include the following steps:

[0074] Step 1a, when the target blank is heated to a first temperature in the heating furnace of the current working step, the sliding door of the target heating furnace is opened to a first opening degree.

[0075] The first temperature is lower than the heating temperature required by the current working step, and the first opening degree is less than the maximum opening degree of the sliding door.

[0076] Step 2a, when the target blank is heated to a second temperature in the heating furnace of the current working step, the sliding door of the target heating furnace is opened to a second opening degree.

[0077] The second temperature is higher than the first temperature and lower than a heating temperature required for the current working step, and the second opening degree is greater than the first opening degree.

[0078] Alternatively, the second opening degree can be a maximum opening degree of the sliding gate, or in other words, the second opening degree can be 100%.

[0079] For example, assuming that the first temperature is 700°C, the first opening degree is 50%, the second temperature is 750°C, and the second opening degree is 100%, when the target blank is heated to 700°C in the heating furnace of the current working step, the intelligent control device can open the sliding gate of the target heating furnace of the next working step to an opening degree of 50%, and when the target blank is heated to 750°C in the heating furnace of the current working step, the sliding gate of the target heating furnace of the next working step is opened to an opening degree of 100%.

[0080] In other possible embodiments, as described above, the heating progress of the target blank in the current working step can also be represented by a heating time length. The intelligent control device can also control the opening degree of the sliding gate according to the heating time length, so as to control the heating rate of the target heating furnace to the surrounding vacuum environment. In this case, S102 described above can also specifically include the following steps:

[0081] Step 1b, in the case where the heating time length of the target blank in the heating furnace of the current working step reaches a first time length, the sliding gate of the target heating furnace is opened to a first opening degree.

[0082] The first time length is shorter than a heating time length required for the current working step, and the first opening degree is less than a maximum opening degree of the sliding gate.

[0083] Step 2b, in the case where the heating time length of the target blank in the heating furnace of the current working step reaches a second time length, the sliding gate of the target heating furnace is opened to a second opening degree.

[0084] The second time length is longer than the first time length, and the second time length is shorter than the heating time length required for the current working step, and the second opening degree is greater than the first opening degree.

[0085] For example, assuming that the first time length is 25 minutes, the first opening degree is 50%, the second time length is 28 minutes, and the second opening degree is 100%, when the target blank is heated to 25 minutes in the heating furnace of the current working step, the sliding gate of the target heating furnace of the next working step is opened to an opening degree of 50%, and when the target blank is heated to 28 minutes in the heating furnace of the current working step, the sliding gate of the target heating furnace of the next working step is opened to an opening degree of 100%.

[0086] In the intelligent control method of the fully-closed vacuum isothermal forging system provided by the embodiments of the present application, the intelligent control device can control the opening degree of the sliding door of the target heating furnace by different heating temperatures or different heating durations when the target heating furnace is controlled to heat in advance, and the greater the opening degree of the sliding door, the greater the heating rate of the target heating furnace to the surrounding vacuum environment, so that the heating rate of the target heating furnace to the surrounding vacuum environment can be controlled by controlling the opening degree of the sliding door, thereby avoiding the poor sealing caused by the material expansion of the vacuum environment (for example, the vacuum tunnel 11) due to the too fast heating rate, and avoiding the influence on the vacuum degree of the vacuum environment.

[0087] In some possible embodiments, as described above, the vacuum pumping unit 300 can also include a vacuum sensor, which can be used to measure the vacuum degree of the vacuum environment (each heating furnace 12, the vacuum tunnel 11 and the vacuum forging chamber 22), and the intelligent control device can also control the target heating furnace to stop heating or continue heating based on the influence of the advance control of the target heating furnace on the vacuum degree of the vacuum environment. In this case, the method can further include the following steps:

[0088] Step 1c, controlling the target heating furnace to stop heating based on the decrease of the vacuum degree of the vacuum environment.

[0089] For example, the intelligent control device can be preset with a vacuum degree decrease threshold value, and when the vacuum degree of the vacuum environment decreases to the vacuum degree decrease threshold value, the intelligent control device can control the target heating furnace to stop heating.

[0090] For example, the vacuum degree decrease threshold value can be set to 5%, 10% or 15% of the normal vacuum degree. The specific value of the vacuum degree decrease threshold value is not limited in the embodiments of the present application.

[0091] For example, taking the normal vacuum degree in the vacuum environment as 0.04 mba, and taking the vacuum degree decrease threshold value as 10% of the normal vacuum degree as an example, when the vacuum degree of the vacuum environment decreases by 0.004 mba, the intelligent control device can control the target heating furnace to stop heating.

[0092] Alternatively, the control device can also control the target heating furnace to continue heating based on the fact that the vacuum degree of the vacuum environment does not decrease.

[0093] In the intelligent control method of the fully-closed vacuum isothermal forging system provided by the embodiments of the present application, the intelligent control device can control the target heating furnace to stop heating based on the decrease of the vacuum degree of the vacuum environment when the target heating furnace is controlled to heat in advance. The decrease of the vacuum degree of the vacuum environment can be a leakage of the vacuum environment, and stopping the advance heating of the target heating furnace can avoid the leakage caused by the heating of the vacuum environment.

[0094] In some possible embodiments, before obtaining the target heating task of the target blank, the intelligent control device can also select the target blank from the plurality of candidate blanks, where the heating process of the target blank comprises a plurality of working steps. In this case, before S101, the method can further comprise the following steps:

[0095] Step 1d, obtaining the heating task of the plurality of candidate blanks.

[0096] The specific process of step 1d can refer to the description of S101 above, and will not be repeated here.

[0097] Step 2d, selecting the candidate blank as the target blank from the plurality of candidate blanks, where the heating task of the target blank comprises a plurality of working steps, and the plurality of working steps indicate that the heating furnace for heating comprises a plurality of heating furnaces.

[0104] In some possible embodiments, the second opening degree is the maximum opening degree of the sliding door.
