[0029] Ultra-thin rectangular metal casings typically have extremely thin walls, generally between 0.1-0.2 mm, while their length and width dimensions exceed 20 mm. Traditional forming processes mainly include stamping and stretching. However, due to the extremely thin walls of ultra-thin rectangular metal casings, product deformation is easily caused during the forming process.
[0030] This application provides a rolling device; please refer to [link / reference]. Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of the rolling apparatus provided in this application. The rolling apparatus 10 of this embodiment includes at least two rolling assemblies 110 and at least two heating elements 120.
[0031] Two rolling assemblies 110 are arranged opposite to each other, and a rolling area 130 is formed between the two rolling assemblies 110. The rolling area 130 is used to place the rolling piece 150 for rolling.
[0032] In some embodiments, two rolling assemblies 110 are positioned opposite each other to form a closed rolling region 130, and a rolled piece 150 is placed in the rolling region 130 so that the two rolling assemblies 110 roll the rolled piece 150.
[0033] Each heating element 120 is disposed on the corresponding rolling assembly 110 and is used to heat the rolled piece 150 being rolled by the rolling assembly 110 to eliminate the stress of the rolled piece 150 being rolled.
[0034] The heating element 120 includes, but is not limited to, electric heating, induction heating, hot air heating, or infrared heating.
[0035] In some embodiments, each rolling assembly 110 is provided with a corresponding heating element 120, and the rolling element 150 is rolled by two rolling assemblies 110. Since the rolling element 150 is subjected to external force during the rolling process, stress will be generated, which will cause the rolling element 150 to deform. At this time, the heating element 120 heats the rolling element 150 in real time through the rolling assembly 110, which can eliminate the stress of the rolling element 150 during the rolling process.
[0036] In this embodiment, the workpiece 150 is rolled by the rolling area 130 between two relatively arranged rolling assemblies 110, ensuring that the workpiece 150 is subjected to uniform stress during the rolling process; and the workpiece 150 is heated by the heating element 120 during the rolling process to eliminate the stress of the workpiece 150 and effectively reduce the problem of product deformation.
[0037] According to some embodiments of this application, see Figure 1 As shown, each rolling assembly 110 in this embodiment includes a bearing 111, a first roll 112, and a second roll 113, with the first roll 112 and the second roll 113 spaced apart on the bearing 111. The first roll 112 and the second roll 113 are rolling rolls.
[0038] In some embodiments, the first roll 112 and the second roll 113 of each rolling assembly 110 are spaced apart on the bearing 111, and the first roll 112 and the second roll 113 are arranged close to each other; the two rolling assemblies 110 are arranged opposite to each other, and a rolling region 130 is formed between the first roll 112 and the second roll 113 of the two rolling assemblies 110, that is, the rolling region 130 is formed by four rolls.
[0039] In this embodiment, by setting the first roll 112 and the second roll 113 at intervals, the rolling device 10 can realize multi-roll operation, which improves processing efficiency and reduces energy consumption and equipment wear during the processing.
[0040] According to some embodiments of this application, a heating element 120 is disposed within a bearing 111, and the heating element 120 is used to heat the rolled workpiece 150 being rolled by a first roll 112 and a second roll 113.
[0041] In some embodiments, the heating element 120 is disposed within the bearing 111. The heat generated by the heating element 120 is first transferred to the bearing 111, and then transferred through the bearing 111 to the first roll 112 and the second roll 113. At this time, the rolling element 150 is rolled by the first roll 112 and the second roll 113 of the two rolling assemblies 110. The first roll 112 and the second roll 113 transfer heat to the rolling element 150 to eliminate the stress of the rolling element 150 during rolling.
[0042] This embodiment reduces the space occupied by the external heating device by placing the heating element 120 inside the bearing 111, making the entire rolling device 10 more compact and suitable for use in limited spaces.
[0043] According to some embodiments of this application, see Figure 2 As shown, Figure 2This is a schematic diagram of an embodiment of the rolling device provided in this application for rolling a workpiece. The rolling device 10 in this embodiment also includes a support member 160, which is disposed inside the workpiece 150 for supporting the workpiece 150.
[0044] In some embodiments, a support member 160 is placed inside the rolled piece 150, and the rolled piece 150 with the support member 160 is rolled by the rolling assembly 110. At this time, the support member 160 can support the inner shape of the rolled piece 150 to prevent the rolled piece 150 from deforming or collapsing during the rolling process. The shape of the support member 160 is the same as the preset shape of the rolled piece 150 after rolling, and the shape of the support member 160 includes, but is not limited to, a columnar shape.
[0045] In this embodiment, by setting the support member 160 inside the roll member 150, a stable internal support can be provided for the roll member 150 during the rolling process, effectively controlling the internal dimensions of the roll member 150 and preventing local deformation or collapse caused by external forces.
[0046] According to some embodiments of this application, see Figure 1 As shown, the rolling device 10 of this embodiment also includes at least two wires 140, each wire 140 being electrically connected to a corresponding heating element 120 to supply power to the heating element 120 through the wires 140.
[0047] For example, such as Figure 1 As shown, the rolling device 10 includes two heating elements 120, which are respectively disposed in the corresponding rolling assembly 110; the rolling device 10 also includes two wires 140, with the heating element 120 and the wire 140 corresponding one-to-one.
[0048] In this embodiment, each wire 140 is electrically connected to the corresponding heating element 120. The heating element 120 can be independently controlled through the wire 140, and the temperature of the heating element 120 can be precisely controlled through the wire 140 to achieve uniform heating of the rolled piece 150.
[0049] According to some embodiments of this application, the cross-sectional shape of the rolling region 130 matches the cross-sectional shape of the rolled piece 150.
[0050] In some embodiments, a closed rolling region 130 is formed between the two sets of rolling assemblies 110. When the rolled piece 150 is rolled through the rolling region 130, since the cross-sectional shape of the rolling region 130 matches the cross-sectional shape of the rolled piece 150 after rolling, the external dimensions of the rolled piece 150 can be effectively controlled through the rolling region 130.
[0051] In this embodiment, the cross-sectional shape of the rolling region 130 matches the cross-sectional shape of the rolled part 150, which ensures that the rolled part 150 deforms along a predetermined shape during the rolling process, thereby achieving a precise forming effect.
[0052] According to some embodiments of this application, the rolls of each roll assembly 110 are correspondingly arranged to a surface of the roll piece 150, and the rolls of the roll assembly 110 are used to roll the surface of the corresponding roll piece 150.
[0053] In some embodiments, the rolling device 10 includes two rolling assemblies 110, and the rolling of each rolling assembly 110 is arranged corresponding to the two surfaces of the rolling piece 150, that is, the rolling of each rolling assembly 110 rolls the two surfaces of the rolling piece 150.
[0054] For example, such as Figure 1 As shown, when the cross-sectional shape of the rolled piece 150 after rolling is rectangular, the cross-sectional shape of the corresponding rolling area 130 is also rectangular. The rollers of each rolling assembly 110 are used to roll the two surfaces of the rolled piece 150.
[0055] In some embodiments, the rolling apparatus 10 includes two rolling assemblies 110, each including a first roll 112 and a second roll 113. The first roll 112 and the second roll 113 are respectively disposed corresponding to a surface of the rolling element 150, so that the first roll 112 and the second roll 113 respectively roll the corresponding surface of the rolling element 150. For example, when the cross-sectional shape of the rolling element 150 after rolling is rhomboid, the cross-sectional shape of the corresponding rolling region 130 is also rhomboid, and the rolling of the rolling assembly 110 is used to roll the corresponding surface of the rolling element 150.
[0056] In this embodiment, the rolls of each rolling assembly 110 are arranged to correspond to the surface of the rolled piece 150, which can ensure that the external force on the rolled piece 150 during the processing is evenly distributed, thereby improving the dimensional accuracy and shape stability of the product.
[0057] According to some embodiments of this application, the heating element 120 has a heating temperature range between 300-800°C. The heating temperature of the heating element 120 includes, but is not limited to, 300°C, 400°C, 500°C, 600°C, 700°C, or 800°C.
[0058] In this embodiment, within a temperature range of 300-800℃, the heating element 120 can effectively eliminate the residual stress generated during the processing of the rolled part 150.
[0059] According to some embodiments of this application, see Figure 1 As shown, the cross-sectional shape of the rolling region 130 in this embodiment includes a rectangle.
[0060] like Figure 1 As shown, a rolling region 130 with a rectangular cross-section is formed between the two rolling assemblies 110. After the rolled piece 150 is rolled through the rolling region 130, the cross-sectional shape of the rolled piece 150 is rectangular.
[0061] In other embodiments, the cross-sectional shape of the rolling region 130 can be trapezoidal, circular, triangular, or polygonal. Furthermore, the cross-sectional shape of the rolling region 130 can be configured according to the desired shape of the rolled workpiece 150 after rolling, thereby improving the applicability of the rolling apparatus 10.
[0062] Another embodiment of this application provides a rolling mill, including a drive assembly, a control assembly, and a rolling device 10 as described in the above embodiment. The control assembly is connected to both the drive assembly and the rolling device 10, and is used to control the drive assembly to drive the rolling device 10 to roll the workpiece. The control assembly includes, but is not limited to, a controller; the drive assembly includes, but is not limited to, a motor.
[0063] In summary, this application rolls the rolled piece 150 through the rolling area 130 between two relatively arranged rolling assemblies 110, ensuring that the rolled piece 150 is subjected to uniform stress during the rolling process; and during the rolling process, the rolled piece 150 is heated by the heating element 120 to eliminate the stress of the rolled piece 150 and effectively reduce the problem of product deformation.
[0064] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
