DETAILED DESCRIPTION

[0073] 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.

[0074] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0075] See also Figure 1-Figure 5 , a rolling processing device for metal materials, including: a rolling mechanism, a cooling mechanism and a control device 1.

[0076] Among them, the calendering mechanism includes: a first conveying device 48 and a fixed frame 7, a height adjustment mechanism 8 is fixedly connected to the bottom of the fixed frame 7, and the height adjustment mechanism 8 can be a lifting cylinder. A U-shaped calendering frame 9 is fixedly connected to the top of the fixed frame 7, and the two ends of the calendering frame 9 are fixedly connected to the top of the fixed frame 7. A first calendering roller 10 is rotatably connected between the two side plates of the calendering frame 9, and a first motor 12 is connected to one of the side plates of the calendering frame 9, and the output end of the first motor 12 is connected to the first calendering roller 10; a chute is provided on both side plates of the calendering frame 9, and the chute is located below the first calendering roller 10, and a lifting mechanism is connected to the bottom of the chute, and the lifting mechanism 51 can be an electric telescopic rod, the telescopic end of the electric telescopic rod faces upward, and the telescopic end is connected to a fixed plate 52, and a second calendering roller 11 is rotatably connected between the two fixed plates 52, and a second motor 13 is connected to one of the fixed plates 52, and the output end of the second motor 13 is connected to the second calendering roller 11, and the second calendering roller 11 is located directly below the first calendering roller 10.

[0077] The first conveying device 48 can be a conveyor belt device, which is placed on one side of the fixed frame 7. The lifting mechanism 51 can drive the two fixed plates 52 to slide in the slide groove, thereby driving the second calendering roller 11 to move up and down, and adjust the distance between the first calendering roller 10 and the second calendering roller 11. After adjusting the distance between the first calendering roller 10 and the second calendering roller 11, the height of the fixed frame 7 is adjusted through the height adjustment mechanism 8, so that the metal sheets calendered by the first calendering roller 10 and the second calendering roller 11 are just flush with the first conveying device 48.

[0078] It should be noted that the cooling of metal is affected by many factors, including the rate of change of temperature and pressure. Rapid cooling may cause metal damage and deformation, while slow cooling can enhance the performance of metal materials. Therefore, when handling and processing metal materials, it is necessary to select an appropriate cooling rate according to the specific situation to ensure the quality and performance of the material. For example, when cooling steel after processing, the cooling rate should be very slow to fully eliminate the stress in the material and improve the plasticity of the material. In addition, slow cooling can also improve hardness, electrical conductivity and corrosion resistance. Temperature change is the main factor that causes metal bending, but high pressure during the cooling process can also cause metal plastic deformation.

[0079] Therefore, in the present invention, a plurality of cooling mechanisms are provided for cooling the rolled metal sheets, and the cooling mechanisms include: a cooling box 2, electric opening and closing doors 14 are provided on opposite sides of the cooling box 2, a second conveying device 49 is provided inside, and the second conveying device 49 can be a conveyor belt device, a pressure sensor 5 and a first temperature sensor 6 are also installed in the cooling box 2, and an air inlet valve assembly 3 and an air outlet valve assembly 4 are provided on the side wall of the cooling box 2; the gas conveying device includes: a gas preparation device 15 and a gas storage box 16, the gas preparation device 15 is connected to the inlet of the gas storage box 16, and the outlet of the gas storage box 16 is connected to the air inlet valve assembly 3.

[0080] Since different metal materials have different properties, the cooling speed will also be different. For example, materials such as high-strength steel and aluminum alloy are more susceptible to deformation or damage than materials such as ordinary steel. Therefore, when processing, it is necessary to select an appropriate cooling speed according to the material properties; when cooling, multiple cooling boxes 2 are arranged in sequence on the other side of the first conveying device 48. In the initial stage, the control device calls up a preset cooling scheme based on the basic properties of the metal sheet to be calendered, and the control device sets the cooling temperature and holding pressure range in the cooling box 2 based on the cooling scheme. The basic properties of the metal sheet include the thickness of the sheet after calendering and the material of the metal blank.

[0081] The storage module of the control device pre-stores a cooling scheme, which includes: the most suitable holding pressure range for different metal materials at different thicknesses, the cooling temperature of the first cooling box 2 and the temperature difference between the cooling temperatures in two adjacent cooling boxes 2.

[0082] After the calendering mechanism forms the metal blank, the control device calls up a cooling scheme that matches the metal sheet according to the basic properties of the metal sheet, sets the cooling temperature in the first cooling box 2 according to the cooling scheme, and then sets the cooling temperature in the subsequent cooling box 2 according to the temperature difference of the cooling scheme. The holding pressure ranges in multiple cooling boxes 2 are the same. After setting the holding pressure range and cooling temperature of each cooling box 2, the control device controls the gas preparation equipment 15 of the corresponding cooling box 2 to prepare temperature regulating gas of corresponding temperature to the gas storage box 16, which is then transported to the cooling box 2 through the gas storage box 16, so that each cooling box 2 is cooled to its respective cooling temperature while the pressure is within the holding pressure range. Then, the electric opening and closing door 14 of the first cooling box 2 toward the first conveying device 48 is opened, and the calendered metal sheet is conveyed to the second conveying device 49 of the first cooling box 2 through the first conveying device 48, and then the electric The opening and closing door 14 is used to cool the metal sheet by the cooling temperature of the first cooling box 2. For example, if the initial temperature of the metal blank is 30°C, the cooling temperature of the first cooling box 2 can be set to 25°C, and the metal sheet at 30°C can be slowly cooled by the temperature of 25°C. After cooling for a certain period of time, the other electric opening and closing door 14 of the first cooling box 2 is opened, and the electric opening and closing door 14 of the second cooling box 2 toward the first cooling box 2 is opened, and the cooled metal sheet is transported to the second conveying device 49 of the second cooling box 2 by the second conveying device 49 of the first cooling box 2. The electric opening and closing door 14 is closed, and the cooling temperature of the second cooling box 2 can be set to 20°C, and the metal sheet at 25°C can be slowly cooled by the temperature of 20°C. By analogy, the temperature after rolling is slowly cooled, which reduces the cooling rate of the metal sheet and prevents the deformation of the metal sheet caused by the rapid temperature change rate.

[0083] It should be noted that in the initial state, the temperature inside the cooling box 2 is at room temperature. When the temperature of the metal plate to be cooled is higher than room temperature, for example, 50°C, in order to reduce the cooling rate, the temperature inside the cooling box 2 needs to be increased, for example, to 45°C, and the metal plate at 50°C is cooled by 45°C; when the temperature of the metal plate to be cooled is lower than room temperature, the temperature inside the cooling box 2 needs to be lowered. Therefore, the gas preparation equipment 15 includes an air refrigerator and a hot air preparation equipment.

[0084] In addition, when each cooling box 2 cools the metal plate, the temperature inside the cooling box 2 will rise. At this time, it is necessary to input temperature regulating gas again to adjust it to keep it at the cooling temperature. In order to keep the pressure in the cooling box 2 within the pressure maintaining range, it is necessary to discharge some gas. At this time, the control device 1 can control the opening of the air inlet valve assembly 3 and the air outlet valve assembly 4 based on the cooling temperature and the pressure maintaining range, thereby controlling the dynamic balance of temperature and pressure inside the cooling box 2.

[0085] Furthermore, the intake valve assembly 3 includes: a first cylinder 17, a first connecting rod 19, a first connecting plate 20, a first valve core 21, a first blocking portion 22, a first telescopic rod 24, a first spring 25 and an intake hole 23 provided on the side wall of the cooling box 2, the first cylinder 17 is fixed to the outer wall of the cooling box 2 by a first fixing rod 18, the first connecting rod 19 is slidably connected to the side wall of the cooling box 2, and one end is located outside the cooling box 2, and the other end is located inside the cooling box 2; the first connecting plate 20 is connected to the end of the first connecting rod 19 located outside the cooling box 2, and the first cylinder 1 The telescopic end of 7 is in contact with the first connecting plate 20; the first valve core 21 is located in the cooling box 2, and is connected to the end of the first connecting rod 19 located in the cooling box 2; the first shielding portion 22 is connected to the side wall of the first valve core 21, and the first shielding portion 22 is in contact with the inner wall of the cooling box 2; the air inlet 23 is connected to the gas storage box 16, and corresponds to the position of the first shielding portion 22; the first telescopic rod 24 is connected between the first valve core 21 and the inner wall of the cooling box 2; the first spring 25 is sleeved on the first telescopic rod 24, and the two ends are respectively connected to the first valve core 21 and the inner wall of the cooling box 2.

[0086] When controlling the opening of the intake valve assembly 3, the control device 1 controls it through the advancement and retreat stroke of the first cylinder 17. When it is necessary to increase the opening of the intake valve assembly 3, the telescopic end of the first cylinder 17 can be controlled to extend to push the first connecting plate 20, the first spring 25 can extend, and the first valve core 21 can be pushed through the first connecting rod 19. At this time, the opening of the intake hole 23 increases; when it is necessary to reduce the opening of the intake valve assembly 3, the telescopic end of the first cylinder 17 can be controlled to contract. At this time, the first spring 25 contracts, pulling the first valve core 21 to block the intake hole 23.

[0087] The air outlet valve assembly 4 includes: a valve body 26, an air outlet hole 30 arranged on the side wall of the cooling box 2, a second cylinder 31, a third cylinder 32, a second connecting rod 35, a third connecting rod 36, a second connecting plate 37, a third connecting plate 38, a second valve core 39, a third valve core 40, a second blocking portion 41, a third blocking portion 42, a fourth blocking portion 43, a second telescopic rod 44, a second spring 45, a third telescopic rod 46, a third spring 47, and a second temperature sensor 50.

[0088] An air inlet 27, a first air outlet 28 and a second air outlet 29 are provided on the side wall of the valve body 26. The air inlet 27 is connected to the air outlet 30 through a pipeline. The second cylinder 31 and the third cylinder 32 are connected to the top and bottom of the valve body 26 respectively through the second fixing rod 33 and the third fixing rod 34. The second connecting rod 35 and the third connecting rod 36 are slidably connected to the top and bottom of the valve body 26 respectively, and one end is located outside the valve body 26, and the other end is located inside the valve body 26; the second connecting plate 37 and the third connecting plate 38 are respectively connected to the ends of the second connecting rod 35 and the third connecting rod 36 located outside the valve body 26, the telescopic end of the second cylinder 31 contacts the second connecting plate 37, and the telescopic end of the third cylinder 32 contacts the third connecting plate 38; the second valve core 39 and the third valve core 40 are located in the valve body 26, and are connected to the second connecting rod 35 and the third connecting rod 36 respectively. The three connecting rods 36 are connected at the ends located inside the valve body 26; the second shielding portion 41 is connected to the side wall of the second valve core 39, contacts the inner wall of the valve body 26, and corresponds to the position of the air inlet 27; the third shielding portion 42 and the fourth shielding portion 43 are connected to the side wall of the third valve core 40, contacts the inner wall of the valve body 26, and correspond to the positions of the first air outlet 28 and the second air outlet 29 respectively; the second telescopic rod 44 is connected between the second valve core 39 and the inner wall of the valve body 26; the second spring 45 is sleeved on the second telescopic rod 44, and the two ends are respectively connected to the second valve core 39 and the inner wall of the valve body 26; the third telescopic rod 46 is connected between the third valve core 40 and the inner wall of the valve body 26; the third spring 47 is sleeved on the third telescopic rod 46; the first air outlet 28 is connected to the gas storage box 16; the second temperature sensor 50 is installed in the valve body 26.

[0089] When controlling the opening of the outlet valve assembly 4, the control device 1 controls it through the advancement and retreat stroke of the second cylinder 31. When it is necessary to increase the opening of the outlet valve assembly, the telescopic end of the second cylinder 31 can be controlled to extend to push the second connecting plate 37, the second spring 45 can extend to push the second valve core 39. At this time, the opening of the air inlet 27 increases, and the gas in the cooling box 2 can enter the valve body 26. When it is necessary to reduce the opening of the outlet valve assembly 4, the telescopic end of the second cylinder 31 can be controlled to contract, the second spring 45 can contract, and the second valve core 39 can be pushed. At this time, the opening of the air inlet 27 is reduced.

[0090] The second temperature sensor 50 monitors the temperature of the gas entering the valve body 26 in real time, and sends the detected first temperature value to the control device 1. The control device 1 compares the first temperature value with the second temperature value of the temperature-regulated gas in the gas storage box 16. When the difference between the first temperature value and the second temperature value exceeds the set threshold value, the control device controls the telescopic end of the third cylinder 32 to extend, and pushes the third valve core 40 through the third connecting rod 36, and the third spring 47 extends. At this time, the third blocking portion 42 just blocks the first air outlet 28, and the fourth blocking portion 43 just opens the second air outlet 29, and the gas entering the valve body 26 is discharged to the outside from the second air outlet 29. When it does not exceed the set threshold value, the third cylinder 32 is controlled to retreat, and the third spring 47 contracts. At this time, the third blocking portion 42 just opens the first air outlet 28, and the fourth blocking portion 43 just blocks the second air outlet 29, and the gas entering the valve body 26 enters the gas storage box 16 from the first air outlet 28 for recovery.

[0091] It should also be noted that a three-dimensional scanning device 55 is also provided in the present invention. After the last cooling box 2 completes the cooling, the control device controls the three-dimensional scanning device 55 to perform a three-dimensional scan on the metal sheet, obtain three-dimensional scanning data, and model the metal sheet based on the three-dimensional scanning data to obtain a three-dimensional model and spatial coordinate data of the metal sheet. In addition, a three-dimensional model of a standard part and spatial coordinate data are pre-stored in the storage unit of the control device. After obtaining the three-dimensional model and spatial coordinate data of the metal sheet, the three-dimensional model of the standard part and the three-dimensional model of the metal sheet are displayed on the display device, and the center points of the three-dimensional model of the standard part and the three-dimensional model of the metal sheet are overlapped. Several detection points are randomly selected in the three-dimensional model of the metal sheet, and the distance from the detection point to the corresponding point of the three-dimensional model of the standard part is calculated. A distance threshold is preset. If the distance is less than the distance threshold, it can be determined that the metal sheet after cooling is not bent.
