[0033] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0034] Figure 1 A schematic diagram of the structure of an aluminum mirror hot pressing forming apparatus 100 according to an embodiment of the present invention is shown. Figure 1 As shown, the aluminum mirror hot pressing forming equipment includes a loading module 110, a heating module 120, a hot pressing module 130, a solution treatment module 140, a quenching module 150, an artificial aging module 160, and a cooling module 170. Each module is described below.

[0035] The loading module 110 is used to load the mold and the aluminum alloy blank to be processed into the heating module, and to transfer the mold and aluminum alloy sequentially between the modules along the preset process direction.

[0036] The mold is used for hot pressing aluminum alloy blanks. Specifically, after the aluminum alloy blank is placed in the mold, the mold is subjected to a series of steps including heating, hot pressing, solution treatment, quenching, artificial aging, and cooling to obtain an aluminum mirror of the desired shape. The mold can be divided into upper and lower parts, but this is just an example. It should be noted that the specific structure of the mold is determined by the desired shape of the aluminum mirror; therefore, the present invention does not limit the structure of the mold. In specific embodiments, those skilled in the art can make settings according to actual needs.

[0037] In this embodiment, in addition to loading the mold and the aluminum alloy blank to be processed into the heating module, the loading module also transfers the heated mold and the aluminum alloy inside the mold to the hot pressing module after the hot pressing module has finished heating the mold and the aluminum alloy inside the mold. Similarly, after the hot pressing module has finished hot pressing the aluminum alloy in the mold, the loading module also moves the hot-pressed mold and the aluminum alloy inside it to the solution treatment module. This process is repeated to process the aluminum alloy step by step, and finally obtain an aluminum mirror.

[0038] Additionally, the heating module 120 is used to heat the aluminum alloy blank. The hot pressing module 130 is used to hot press the heated aluminum alloy blank into shape, that is, to heat and press the aluminum alloy inside the mold by heating and pressurizing the mold. The solution treatment module 140 is used to solution treat the hot-pressed aluminum alloy. The quenching module 150 is used to quench the solution-treated aluminum alloy. The artificial aging module 160 is used to artificially age the quenched aluminum alloy. The cooling module 170 is used to cool the artificially aged aluminum alloy to obtain an aluminum mirror.

[0039] It should be noted that the present invention does not limit the specific heating temperature, the specific pressure, and the specific cooling temperature in the above modules. In specific embodiments, those skilled in the art can set these parameters according to actual needs.

[0040] The following is a detailed description of the aluminum mirror hot pressing forming equipment. The aluminum mirror hot pressing forming equipment consists of two parts: a forming cavity (including the outer shell) and an electrical box. The forming cavity is located above the electrical box, as shown below. Figure 2 and 3 The forming cavity includes a heating module, a hot pressing module, a solution treatment module, a quenching module, an artificial aging module, and a cooling module, such as... Figure 4 .

[0041] The following is a detailed explanation of each module. Figure 5 A schematic diagram of an aluminum mirror hot-pressing forming apparatus according to yet another embodiment of the present invention is shown. Figure 5 As shown, the aluminum mirror hot pressing forming equipment includes an electrical, water, and gas component box (i.e., the electrical box mentioned above), a housing, and a forming cavity (the space inside the housing is called the forming cavity; in this embodiment, the forming cavity and housing are shown separately to more clearly illustrate the equipment). The forming cavity includes a heating module, a hot pressing module, a solution treatment module, a quenching module, an artificial aging module, and a cooling module.

[0042] The heating module is used to heat the aluminum alloy blank. Specifically, in this embodiment, the heating module may include: a first cylinder, two sets of cooling plates, two sets of heating plates, a first temperature sensor for monitoring the temperature of the heating plates, and a first temperature control device.

[0043] Two sets of heating plates are positioned opposite each other and at a predetermined distance, forming a heating station for heating the aluminum alloy blank. Two sets of cooling plates are fixed to the outer sides of the two sets of heating plates, respectively. Figure 5 The color indicators indicate that the heating plate corresponds to the darker areas, and the cooling plate to the lighter areas. Figure 5 As can be seen, the heating module includes two sets of heating plates, one set located on the upper side and the other on the lower side. Each set of heating plates can consist of two (not limited to two) heating plates arranged side by side. Furthermore, the two sets of heating plates are opposite each other and spaced a preset distance apart. This creates a space for heating the aluminum alloy blank; this space is called the heating station. A cooling plate is fixed to the outside of each set of heating plates.

[0044] In this embodiment, the guide rod of the first cylinder passes through the outer casing and connects to the cooling plate, meaning the first cylinder is located above the upper cooling plate. For details regarding the specific structure of the heating module, please refer to [link / reference needed]. Figure 6 .

[0045] In addition, in this embodiment, the first temperature sensor can be placed in the upper and lower heating plates close to the heating station (i.e., the first temperature sensor is placed in both the upper and lower heating plates) to accurately control the temperature on both sides of the heating station, thereby enabling the mold and aluminum alloy to obtain a more uniform temperature. Therefore, the temperature of the heating station can be obtained by measuring the temperature of the heating plate that is in contact with the heating station.

[0046] Specifically, in this embodiment, the mold and aluminum alloy blank are first moved to the heating station. After the mold and aluminum alloy blank arrive at the heating station, the process of heating the aluminum alloy may include:

[0047] The first cylinder drives a set of heating plates downwards, that is, the first cylinder presses down on the upper cooling plate, thereby driving the upper heating plate downwards, so that the two sets of heating plates are in contact with the mold and held for a first time. During the first time, the first temperature control device adjusts the temperature of the heating plate and the cooling plate according to the temperature feedback from the first temperature sensor, so that the temperature of the first temperature sensor is controlled at a preset first temperature. After the first time is reached, the first cylinder drives the lowered heating plate upwards to detach from the mold. At this point, the heating of the aluminum alloy blank is completed, and the heated aluminum alloy is obtained. The first time can be 1 to 10 minutes, and the first temperature can be 300 to 450°C. Of course, this is only an example, and the present invention is not limited thereto. In specific embodiments, those skilled in the art can set it according to actual needs.

[0048] Next, the mold and the aluminum alloy it holds are moved together to the hot pressing module for hot pressing. Specifically, in this embodiment, the hot pressing module may include an electric cylinder, two sets of heating plates, two sets of cooling plates, a second temperature sensor for monitoring the temperature of the heating plates, a second temperature control device, a displacement sensor for monitoring the downward displacement of the heating plates, a displacement control device, a first pressure sensor for monitoring the pressure on the mold, and a first pressure control device. The two sets of heating plates are opposite each other and spaced at a preset distance to form a hot pressing station for the heated aluminum alloy. The two sets of cooling plates are respectively fixed to the outside of the two sets of heating plates.

[0049] correspond Figure 5 The positional relationship between the two sets of heating plates and the two sets of cooling plates can be referenced from the heating module, and will not be repeated here. In the hot pressing module, the guide rod of the electric cylinder passes through the forming cavity and connects to the upper cooling plate, as shown in [reference needed]. Figure 7 In this embodiment, the second temperature sensor can be placed in the heating plates on the upper and lower sides respectively.

[0050] In this embodiment, the hot pressing module may further include a first pressure sensor and a first pressure control device. The first pressure sensor may be placed in the lower cooling plate to monitor the pressure value borne by the mold during the hot pressing process.

[0051] Specifically, after the mold and the heated aluminum alloy arrive at the hot pressing station, the hot pressing module performs a hot pressing process on the heated aluminum alloy, which may include:

[0052] An electric cylinder moves a set of heating plates downwards, specifically by pressing down on the upper cooling plate, which in turn moves the upper heating plate downwards, causing the two sets of heating plates to adhere to the mold and remain in contact for a second duration. A displacement control device, based on data from a displacement sensor, controls the electric cylinder to move the heating plates downwards to a preset pressure amount. A first pressure control device, based on pressure data from a first pressure sensor, controls the electric cylinder to ensure the heating plates exert pressure on the mold to a preset first pressure. During the second duration, a second temperature control device, based on temperature data from a second temperature sensor, adjusts the heating and cooling plates to maintain the temperature monitored by the second temperature sensor at a preset second temperature. After the second duration is reached, the electric cylinder moves the lowered heating plates upwards to detach from the mold, completing the hot-pressing process of the heated aluminum alloy and obtaining the hot-pressed aluminum alloy.

[0053] Here, the second duration, pressure, first pressure, and second temperature are explained. The second duration can be 1 to 10 minutes. The second temperature can be 300 to 450°C. The pressure can vary from a few micrometers to a few millimeters depending on the shape of the hot-pressed material; specifically, the maximum pressure of the equipment can be 100 mm (can be changed). The first pressure can be determined based on the size of the blank being pressed and the hot-pressing temperature; specifically, the maximum pressure of the equipment can be 40 kN (can be changed). It should be noted that the above is only an example. In specific embodiments, those skilled in the art can set the second duration, pressure, first pressure, and second temperature according to actual needs.

[0054] Additionally, in this embodiment, the hot-pressing module may further include an ultrasonic vibration device, which can be placed below the lower cooling plate, such as... Figure 5 It can also be placed on top of the upper cooling plate, such as... Figure 7 This invention does not specifically limit the scope of the invention. Specifically, when it is necessary to improve the deformability of the aluminum alloy or reduce the internal stress of the aluminum mirror, the ultrasonic vibration device begins to vibrate to optimize the deformation process of the aluminum alloy. Specifically, ultrasonic vibration can improve the rheological properties of the aluminum alloy, increase the deformation efficiency of the blank, and reduce the internal stress of the formed aluminum mirror.

[0055] Next, the mold and the hot-pressed aluminum alloy are transferred together to the solution treatment module for solution treatment. Specifically, in this embodiment, the solution treatment module may include: a second cylinder, two sets of heating plates, two sets of cooling plates, a third temperature sensor for monitoring the temperature of the heating plates, a third temperature control device, a second pressure sensor for monitoring the pressure on the mold, and a second pressure control device. The two sets of heating plates are positioned opposite each other and at a predetermined distance, forming a solution treatment station for the hot-pressed aluminum alloy. The two sets of cooling plates are respectively fixed to the outside of the two sets of heating plates. The positional relationship between the heating plates and cooling plates can be referenced from the heating module and will not be elaborated here.

[0056] Additionally, in this embodiment, the guide rod of the second cylinder in the solid solution module passes through the outer casing and connects to the upper cooling plate, as can be seen in [reference needed]. Figure 8 The third temperature sensor can be placed in the upper and lower heating plates of the solution treatment station to precisely control the temperature on both sides of the station, resulting in a more uniform temperature for the mold and the aluminum alloy. The second pressure sensor can be placed in the lower cooling plate to monitor the pressure exerted on the mold.

[0057] In this embodiment, the solution treatment module may perform the solution treatment process on the hot-pressed aluminum alloy, including:

[0058] After the mold and the hot-pressed aluminum alloy are transferred to the solution treatment station, the second cylinder presses down on the upper cooling plate, thereby causing a set of heating plates to move down and adhere to the mold for a third time period. The second pressure control device, based on pressure data from the second pressure sensor, controls the second cylinder to ensure the pressure of the descending heating plates on the mold reaches a preset second pressure. During the third time period, the third temperature control device, based on temperature data from the third temperature sensor, adjusts the temperatures of the heating and cooling plates to maintain the temperature monitored by the third temperature sensor at a preset third temperature. After the third time period is reached, the second cylinder moves the descended heating plates up to detach from the mold, yielding the solution-treated aluminum alloy.

[0059] The third duration can be 3–20 minutes. The third temperature can be 510–580°C. The second pressure can be determined based on the size of the blank being pressed and the hot-pressing temperature; specifically, the maximum pressure of the equipment can be 40 kN (which can be changed). It should be noted that the above is only an example, and in specific embodiments, those skilled in the art can set it according to actual needs.

[0060] Next, the mold and the solution-treated aluminum alloy are transferred together to the quenching module for quenching. Specifically, in this embodiment, the quenching module may include: a third cylinder, two sets of cooling plates, a fourth temperature sensor for monitoring the temperature of the cooling plates, a fourth temperature control device, a third pressure sensor for monitoring the pressure on the mold, and a third pressure control device. The two sets of cooling plates (which may be thickened to maintain a level plane with other workstations) are positioned opposite each other and at a predetermined distance, forming a quenching station for the solution-treated aluminum alloy. Specifically, any set of cooling plates may consist of two (not limited to) cooling plates arranged side-by-side.

[0061] In this embodiment, the guide rod of the third cylinder in the quenching module passes through the outer casing and connects to the upper cooling plate, as shown in the figure. Figure 9 The fourth temperature sensor can be placed in each set of cooling plates near the quenching station to precisely control the temperature on both sides of the quenching station, resulting in a more uniform temperature for the mold and aluminum alloy. The third pressure sensor can be located in the lower set of cooling plates to measure the pressure exerted on the mold.

[0062] In this embodiment, after the mold and the solution-treated aluminum alloy are moved to the quenching station, the quenching process may include: a third cylinder driving a set of cooling plates downwards, so that the upper and lower sets of cooling plates are in contact with the mold and maintained for a preset fourth time period. A third pressure control device controls the third cylinder based on pressure data fed back by a third pressure sensor, so that the pressure of the cooling plates on the mold reaches a preset third pressure. Within the fourth time period, a fourth temperature control device adjusts the cooling plates based on the temperature fed back by a fourth temperature sensor, so that the temperature monitored by the fourth temperature sensor reaches a preset fourth temperature value. After the fourth time period is reached, the third cylinder drives the lowered cooling plates upwards to detach from the mold, obtaining the quenched aluminum alloy.

[0063] The fourth duration can be 1–10 min. The fourth temperature can be 0–25 °C. The third pressure can be determined based on the size of the blank being pressed and the hot pressing temperature; specifically, the maximum pressure of the equipment can be 40 kN (which can be changed). It should be noted that the above is just an example, and in specific embodiments, those skilled in the art can set it according to actual needs.

[0064] In this embodiment, the sealed molding cavity formed by the outer shell is filled with nitrogen. A cooling water channel is installed inside the outer shell, which has water vapor inlets and outlets. A nitrogen storage device and a vacuum pump are connected externally. The nitrogen storage device supplies nitrogen to the molding cavity to protect the components, molds, and aluminum alloy blanks inside the cavity from oxidation and corrosion at high temperatures. The vacuum pump is used to remove air from the molding cavity before the equipment heats up.

[0065] In this embodiment, the quenching module may further include a spraying device. This spraying device sprays low-temperature nitrogen gas onto the location of the mold before the third cylinder moves the lowered cooling plate upwards to detach it from the mold, thereby rapidly cooling the mold and aluminum mirror within the module. The specific location of the spraying device can be determined based on actual conditions, as long as it allows for the spraying of low-temperature nitrogen gas onto the mold.

[0066] In this embodiment, the aluminum mirror hot pressing forming equipment may further include a pressure sensor and a pressure control device. The pressure sensor is used to monitor the pressure inside the forming cavity, and the pressure control device is used to control a vacuum pump to extract a portion of the nitrogen gas after the pressure inside the forming cavity exceeds a preset threshold. The specific location of the pressure sensor can be set according to actual conditions, as long as it can monitor the pressure inside the forming cavity.

[0067] Next, the mold and the quenched aluminum alloy are moved together to the artificial aging module for artificial aging. Specifically, in this embodiment, the artificial aging module may include: a fourth cylinder, two sets of cooling plates, two sets of heating plates, a fifth temperature sensor for monitoring the temperature of the heating plates, and a fifth temperature control device. The two sets of heating plates are positioned opposite each other and at a preset distance, forming an artificial aging station for heating the quenched aluminum alloy. The two sets of cooling plates are fixed to the outer sides of the two sets of heating plates. Specifically, in this embodiment, the specific positional relationship between the two sets of heating plates and the two sets of cooling plates can be referenced from the heating module, and will not be elaborated here.

[0068] In this embodiment, the guide rod of the fourth cylinder passes through the housing and connects to the upper cooling plate, as shown in the figure. Figure 10 The fifth temperature sensor can be placed in the upper and lower heating plates respectively to precisely control the temperature on both sides of the artificial aging station, resulting in a more uniform temperature for the mold and aluminum alloy. In this embodiment, the process of artificially aging the mold and the quenched aluminum alloy may include:

[0069] After the mold and the quenched aluminum alloy are moved to the artificial aging station, the fourth cylinder moves a set of heating plates downwards. Specifically, the fourth cylinder presses down on the upper cooling plate, causing the upper heating plates to move downwards, thus bringing the two sets of heating plates into contact with the mold and maintaining them for a preset fifth time period. During this fifth time period, the fifth temperature control device adjusts the heating and cooling plates based on the temperature feedback from the fifth temperature sensor, keeping the temperature monitored by the fifth temperature sensor at the preset fifth temperature. After the fifth time period is reached, the fourth cylinder moves the lowered heating plates upwards to detach them from the mold, resulting in the artificially aged aluminum alloy.

[0070] The fifth duration can be 3–10 minutes, and the fifth temperature can be 100–250°C. This is merely an example, and the invention is not intended to limit it. In specific embodiments, those skilled in the art can set these parameters according to actual needs.

[0071] Next, the mold and the artificially aged aluminum alloy are moved together to the cooling module for cooling. Specifically, in this embodiment, the cooling module may include: a fifth cylinder, two sets of cooling plates, a sixth temperature sensor for monitoring the temperature of the cooling plates in contact with the mold, and a sixth temperature control device. The two sets of cooling plates (which may be thickened to maintain a level plane with other workstations) are positioned opposite each other at a predetermined distance, forming a cooling station for cooling the quenched aluminum alloy. Specifically, the positional relationship between the two sets of cooling plates can be referenced from the quenching module, and will not be elaborated here.

[0072] In this embodiment, the guide rod of the fifth cylinder passes through the housing and connects to the upper cooling plate, as shown in the figure. Figure 11 The sixth temperature sensor can be placed in one of the two sets of cooling plates close to the cooling station to precisely control the temperature on both sides of the cooling station, so that the mold and aluminum alloy can obtain a more uniform temperature.

[0073] In this embodiment, the cooling process of the cooling module for the artificially aged aluminum alloy may include:

[0074] After the mold and the artificially aged aluminum alloy are moved to the cooling station, the fifth cylinder moves a set of cooling plates downwards, pressing down on the upper cooling plates to bring them into contact with the mold and maintain them for a preset sixth time period. During this sixth time period, the sixth temperature control device adjusts the cooling plates based on the temperature feedback from the sixth temperature sensor, keeping the temperature monitored by the sixth temperature sensor at the preset sixth temperature. After the sixth time period is reached, the fifth cylinder moves the lowered cooling plates upwards to detach them from the mold, resulting in the cooled aluminum mirror.

[0075] The sixth duration can be 1 to 10 minutes, and the sixth temperature can be 20 to 25°C. This is merely an example and is not intended to limit the scope of the invention. In specific embodiments, those skilled in the art can set these parameters according to actual needs.

[0076] Next, the cooled aluminum mirror is removed from the mold to obtain the hot-pressed aluminum mirror.

[0077] In this embodiment, the cooling plate is used for cooling, and in conjunction with the heating plate, it controls the temperature and isolates high temperatures. The cooling plate can be water-cooled. The heating plate is used for heating and, in conjunction with a temperature control system (temperature sensor and temperature control device), maintains the temperature. The heating plate can be electrically heated.

[0078] It should be noted that in this embodiment, the terms "first," "second," etc., preceding the temperature sensor, temperature control device, pressure sensor, and pressure control device are merely for differentiation and have no special meaning. Furthermore, in this embodiment, the heating module, hot pressing module, solution treatment module, quenching module, artificial aging module, and cooling module included in the aluminum mirror hot pressing forming equipment all also include relevant electro-hydraulic and gas components to cooperate with each module in completing its corresponding function. Specifically, these electronic and gas components can be placed in an electro-hydraulic and gas component box.

[0079] To more intuitively demonstrate the aluminum mirror hot pressing process of this invention, the following is provided: Figure 12 The diagram shows a hot pressing process for forming aluminum mirrors. Figure 12 The process consists of, in sequence, a heating module, a hot pressing module, a solution treatment module, a quenching module, an artificial aging module, a cooling module, and a demolding process, transforming the aluminum alloy into an aluminum mirror.

[0080] In this embodiment, the loading module is used to load the mold and the aluminum alloy blank to be processed into the heating module, and to sequentially transfer the mold and aluminum alloy between modules along a preset process direction. Specifically, the loading module may include a first push rod and a second push rod. The first push rod loads the mold and aluminum alloy blank into the heating module. The second push rod transfers the aluminum alloy and mold obtained from one module to the next module along the preset process direction. The first push rod corresponds to... Figure 5 The shorter pusher is indicated by the markings, and the second pusher corresponds to the longer pusher.

[0081] in, Figure 13 This is a schematic diagram of the aluminum mirror hot-pressing transfer process of the present invention. Figure 13 The specific structures of push rod one and push rod two can be seen. In this embodiment, push rod one (the first push rod) pushes the mold and the aluminum alloy blank to be processed into the heating station. Push rod two (the second push rod) pushes the mold along the hot pressing process direction and sequentially transfers it to each station along the hot pressing process direction, completing the alternating progressive process of station loading, heating, hot pressing, solution treatment, quenching, artificial aging, and cooling. Push rod two (the second push rod) is initially located at... Figure 2 Position 1 is shown; the machine first moves along the negative X-axis to position 2, then along the Y-axis to position 3, thereby moving the mold. This streamlined processing further improves the production efficiency of aluminum mirrors.

[0082] In this embodiment, the temperature control diagram of each module in the aluminum mirror hot pressing forming equipment is shown below. Figure 14As shown in the diagram. The horizontal axis represents time, and the vertical axis represents temperature. t0 to t1 is the heating stage, t1 to t2 is the hot pressing stage, t2 to t4 is the solution treatment stage, t4 to t6 is the quenching stage, t6 to t8 is the artificial aging stage, and t8 to t9 is the cooling stage. T0 is room temperature, T1 is the temperature during artificial aging, T2 is the temperature during hot pressing, and T3 is the temperature during solution treatment. That is, the heating and hot pressing stations are set to T2, the solution treatment station is set to T3, the quenching and cooling stations are set to T0, and the artificial aging station is set to T1. Each station reaches its preset temperature before the process begins.

[0083] It should be noted that in actual production, the modules in the aluminum mirror hot pressing forming equipment can be increased or decreased accordingly. Specifically, for example, if the aluminum alloy needs to be heated for a first duration by the heating module, and the heating duration of the heating module in the aluminum mirror hot pressing forming equipment of the present invention is preset to a second duration, if the first duration is a multiple of the second duration, then in this embodiment, the required number of heating modules can be continuously set to complete the required heating duration, and then the hot pressing module processing can be performed.

[0084] The present invention also provides a method for hot pressing aluminum mirrors. Figure 15 A flowchart of a hot pressing method 1500 for forming an aluminum mirror according to an embodiment of the present invention is shown, wherein the method is adapted to be performed in an aluminum mirror hot pressing apparatus.
