[0043] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Figure 1 Schematic diagram of the process of the bending performance detection method of the plate provided in the embodiment of the present application. Figure 1 The embodiment of the present application provides a method for detecting the bending performance of a plate, the execution subject of which may be an electronic device, for example, a controller. The following description is made by taking the execution subject of the method as an example. The method may include:

[0045] Step 110, perform at least one first detection operation until a first test end condition is met, and use the first target bending diameter that meets the first test end condition as the first limit bending diameter of the target type of plate; the first detection operation is to obtain a plate to be tested of the target type, and determine the bending performance of the plate of the target type based on the plate to be tested.

[0046] The plate to be tested may be a rectangular cross-section strip, the thickness t of the plate to be tested may be 0.1 mm to 10 mm, the width b is greater than or equal to 15 mm, and the length l is greater than or equal to 15 mm. Specifically, a rectangular cross-section strip with a thickness t of 3 mm, a width b of 35 mm, and a length l of 100 mm may be selected as the plate to be tested.

[0047] The controller can control the target type of plate to be tested (such as a metal plate) to perform bending performance testing under a certain condition. If the plate to be tested meets the condition, the first limit bending diameter of the target type of plate can be obtained; if the plate to be tested does not meet the condition, the bending performance test is performed under another condition until the plate to be tested meets the test condition and the first limit bending diameter of the target type of plate is obtained.

[0048] The bending performance detection method of the plate provided in the embodiment of the present application can obtain the limit bending diameter of the plate as the limit bending performance of the plate by performing at least one first detection operation of acquiring the target type of plate to be tested and determining the bending performance of the target type of plate based on the plate to be tested, thereby accurately reflecting the bending performance of the plate.

[0049] In one embodiment, the first detection operation includes: obtaining a plate to be tested of a target type corresponding to the current first detection operation, and determining a first target bending diameter corresponding to the current first detection operation; wherein the first target bending diameter corresponding to the first first detection operation is the first bending diameter; bending the plate to be tested with the first target bending diameter, the first bending direction and the first bending angle to obtain a first bent plate; if there is no crack on the first surface of the first bent plate, flattening the first bent plate to obtain a first flattened plate; if the first surface of the first bent plate is cracked or the second surface of the first flattened plate is cracked, increasing the first target bending diameter corresponding to the current first detection operation to obtain a second bending diameter, and using the second bending diameter as the first target bending diameter corresponding to the next first detection operation; the directions of the first surface and the second surface are opposite.

[0050] Figure 2 Schematic diagram of a plate to be tested provided in an embodiment of the present application being bent in a first bending direction. Figure 2 As shown, the target type of the plate to be tested corresponding to the current first detection operation is obtained, and the first target bending diameter is determined. Among them, the first target bending diameter corresponding to the first first detection operation is the first bending diameter, and the first bending diameter can be 0.5t, where t is the thickness of the plate to be tested. The controller can control the plate to be tested to bend with the first target bending diameter, the first bending direction and the first bending angle (such as 90°) to obtain the first bent plate. If there is no crack on the first surface of the first bent plate, the first bent plate is flattened to obtain the first flattened plate. If the second surface of the first flattened plate is cracked, the first detection operation needs to be repeated. If the first surface of the first bent plate is cracked, the first detection operation also needs to be repeated. If there is no crack on the first surface of the first bent plate, and there is no crack on the second surface of the first flattened plate, the first test end condition is met, and the first target bending diameter corresponding to the current first detection operation is the first limit bending diameter. The first limit bending diameter is the limit bending diameter of 90° bent in the first bending direction. Among them, the first surface is in opposite directions to the second surface.

[0051] For example, the first bending diameter can be 0.5t, and the first first detection operation can use 0.5t as the first target bending diameter. The plate to be tested can be controlled to be bent with the first target bending diameter of 0.5t, the first bending direction and the first bending angle (such as 90°) to obtain the first bent plate. If there is no crack on the first surface of the first bent plate, the first bent plate is flattened to obtain the first flattened plate. If there is no crack on the first surface of the obtained first bent plate, and there is no crack on the second surface of the first flattened plate, the first test end condition is met, and the first target bending diameter of 0.5t corresponding to the current (first) first detection operation is the first limit bending diameter. If the first surface of the first bent plate is cracked or the second surface of the first flattened plate is cracked, the first detection operation needs to be repeated. At this time, the test conditions need to be changed, that is, the first target bending diameter of 0.5t of the first first detection operation is increased to obtain the second bending diameter. The second bending diameter can take a value of 1t, and 1t is used as the first target bending diameter corresponding to the next first detection operation (i.e., the second first detection operation). Then, the sheet to be tested is bent with a first target bending diameter 1t, a first bending direction and a first bending angle (such as 90°) to obtain a first bent sheet. If there is no crack on the first surface of the first bent sheet, the first bent sheet is flattened to obtain a first flattened sheet. If there is no crack on the first surface of the obtained first bent sheet, and there is no crack on the second surface of the first flattened sheet, the first test end condition is met, and the first target bending diameter 1t corresponding to the current (second) first detection operation is the first limit bending diameter. If the first test end condition is still not met at this time, that is, the first surface of the first bent sheet is cracked or the second surface of the first flattened sheet is cracked, the first target bending diameter 1t corresponding to the current (second) first detection operation is continued to be increased to obtain a second bending diameter (such as 2t), and the second bending diameter 2t is used as the first target bending diameter corresponding to the next (third) first detection operation. Exemplarily, the first target bending diameter corresponding to the first first detection operation may be 0.5t, the first target bending diameter corresponding to the second first detection operation may be 1t, the first target bending diameter corresponding to the third first detection operation may be 2t, the first target bending diameter corresponding to the fourth first detection operation may be 3t, the first target bending diameter corresponding to the fifth first detection operation may be 4t, the first target bending diameter corresponding to the sixth first detection operation may be 5t, and the first target bending diameter corresponding to the seventh first detection operation may be 6t… until the first test end condition is met.

[0052] The bending performance detection method of the plate provided in the embodiment of the present application performs a first detection operation of obtaining a plate of the target type to be tested at least once and determining the bending performance of the plate of the target type based on the plate to be tested, gradually increases the bending diameter according to the test results, and obtains the limit bending diameter of the plate as the limit bending performance of the plate by determining the cracking conditions of the first surface and the second surface, which can accurately reflect the bending performance of the plate.

[0053] In one embodiment, the bending performance detection method of a plate further includes: performing at least one second determination operation until a second test end condition is met, and using the second target bending diameter that meets the second test end condition as the second limit bending diameter of the plate of the target type, and using the third target bending diameter that meets the second test end condition as the third limit bending diameter of the plate of the target type; wherein the second determination operation includes: determining the second target bending diameter corresponding to the current second determination operation; wherein the second target bending diameter corresponding to the first second determination operation is the first limit bending diameter; based on the second target bending diameter, performing at least one third detection operation to obtain a second bent plate; the third detection operation is an operation of obtaining a plate to be tested of the target type, and determining the bending performance of the plate of the target type based on the plate to be tested; if the second surface of the second bent plate is cracked, and the third target bending diameter is equal to the first preset value, the second target bending diameter corresponding to the current second determination operation is increased to obtain the third bending diameter, and the third bending diameter is used as the second target bending diameter corresponding to the next second determination operation.

[0054] Further, in one embodiment, the third detection operation includes: obtaining a plate to be tested of a target type corresponding to the current third detection operation, and determining a third target bending diameter corresponding to the current third detection operation; wherein, in each second determination operation, the third target bending diameter corresponding to the first third detection operation is a fourth bending diameter, and the fourth bending diameter is determined based on the second target bending diameter; for a first flattened plate that is flattened after being bent with the second target bending diameter, the first bending direction and the first bending angle, bending with the third target bending diameter, the second bending direction and the second bending angle to obtain a second bent plate; the second bending direction is opposite to the first bending direction; if the second surface of the second bent plate is cracked, and the third target bending diameter is less than the first preset value, the third target bending diameter corresponding to the current third detection operation is increased to obtain a fifth bending diameter, and the fifth bending diameter is used as the third target bending diameter corresponding to the next third detection operation.

[0055] Further, in one embodiment, the second test end condition is: there is no crack on the second surface of the second bent plate, and the third target bending diameter is less than or equal to the first preset value.

[0056] In the first second determination operation, the controller can determine that the second target bending diameter corresponding to the first second determination operation is the first limit bending diameter (for example: 1t, t is the thickness of the plate to be measured). Then in the first second determination operation, the plate to be measured of the target type corresponding to the first third detection operation is obtained, and the third target bending diameter corresponding to the first third detection operation is determined. At this time, the third target bending diameter is the fourth bending diameter, and the fourth bending diameter is determined based on the second target bending diameter. The value of the fourth bending diameter can be equal to the second target bending diameter, that is, 1t. The controller bends the first flattened plate that is flattened after bending with the second target bending diameter 1t, the first bending direction (for example: positive bending) and the first bending angle (such as 90°) with the third target bending diameter 1t, the second bending direction (for example: reverse bending) and the second bending angle (such as 90°) to obtain a second bent plate. Among them, the second bending direction is opposite to the first bending direction. If there is no crack on the second surface of the second bent sheet, and the third target bending diameter 1t is less than or equal to the first preset value (e.g., 6t), the second test end condition is met, and the second target bending diameter 1t at this time is used as the second limit bending diameter of the target type of sheet, and the third target bending diameter 1t at this time is used as the third limit bending diameter of the target type of sheet. Specifically, the target type of sheet is flattened after being bent in the first bending direction, i.e., forward bending, and at the first bending angle of 90°, and when being bent in the second bending direction, i.e., reverse bending, and at the second bending angle of 90°, the second limit bending diameter of the forward bending is the second target bending diameter 1t that meets the second test end condition, and the third limit bending diameter of the reverse bending is the third target bending diameter 1t that meets the second test end condition.

[0057] If the second surface of the second bent plate is cracked and the third target bending diameter 1t is less than the first preset value 6t, it is necessary to increase the third target bending diameter corresponding to the current third detection operation (the first third detection operation in the first second determination operation) to obtain the fifth bending diameter (for example: 2t). For example, the fifth bending diameter 2t is used as the third target bending diameter corresponding to the next third detection operation (the second third detection operation in the first second determination operation).

[0058] Then the controller bends the first flattened sheet flattened after bending with the second target bending diameter 1t, the first bending direction, i.e., positive bending, and the first bending angle of 90°, with the third target bending diameter 2t, the second bending direction, i.e., reverse bending, and the second bending angle of 90° to obtain a second bent sheet. If there is no crack on the second surface of the second bent sheet at this time, and the third target bending diameter 2t is less than or equal to the first preset value (e.g., 6t), the second test end condition is met, and the second limit bending diameter at this time is 1t, and the third limit bending diameter is 2t. If the second test end condition is still not met at this time, the third target bending diameter corresponding to the current third detection operation (the second third detection operation in the first second determination operation) is continued to be increased to obtain the fifth bending diameter (e.g., 3t), and the fifth bending diameter 3t is used as the third target bending diameter corresponding to the next third detection operation (the third third detection operation in the first second determination operation), and then based on the second target bending diameter 1t and the third target bending diameter 3t, the third detection operation is performed to see whether the second detection end condition is met...

[0059] If the second target bending diameter is 1t and the third target bending diameter is 6t, the second surface of the second bent sheet is cracked, and the third target bending diameter is equal to the first preset value 6t, the second test end condition is still not met. At this time, the second target bending diameter 1t corresponding to the current (first) second determination operation is increased to obtain a third bending diameter (for example: 2t), and the third bending diameter 2t is used as the second target bending diameter corresponding to the next (second) second determination operation. Then the controller determines the third target bending diameter corresponding to the current third detection operation (the first third detection operation in the second second determination operation), that is, the fourth bending diameter. The fourth bending diameter is determined based on the second target bending diameter and can be the same as the second target bending diameter, that is, 2t, that is, the third target bending diameter is 2t at this time. Then, the first flattened sheet flattened after bending with the second target bending diameter 2t, the first bending direction, i.e., positive bending, and the first bending angle of 90° is bent with the third target bending diameter 2t, the second bending direction, i.e., reverse bending, and the second bending angle of 90° to obtain a second bent sheet. If there is no crack on the second surface of the second bent sheet at this time, and the third target bending diameter 2t is less than or equal to the first preset value (e.g., 6t), the second test end condition is met, and the second limit bending diameter is 2t and the third limit bending diameter is 2t. If the second test end condition is still not met at this time, the third target bending diameter corresponding to the current third detection operation (the first third detection operation in the second second determination operation) is continued to be increased to obtain a fifth bending diameter (e.g., 3t), and the fifth bending diameter 3t is used as the third target bending diameter corresponding to the next third detection operation (the second third detection operation in the second second determination operation), and then based on the second target bending diameter 2t and the third target bending diameter 3t, a third detection operation is performed to see whether the second detection end condition is met... This process is repeated until the second test end condition is met.

[0060] The bending performance detection method of the plate provided in the embodiment of the present application, by performing at least one second determination operation and a third detection operation, obtains the second limit bending diameter of the first bending direction and the third limit bending diameter of the second bending direction after the plate is flattened in the first bending direction and the first bending angle, and when bending in the second bending direction and the second bending angle, can accurately reflect the bending performance of the plate, increase the difficulty of cold bending, and expand the detection range of the plate's limit bending performance.

[0061] In one embodiment, the bending performance detection method of a plate further includes: performing at least one fourth determination operation until a third test end condition is met, and using a fourth target bending diameter that meets the third test end condition as a fourth limit bending diameter of the target type of plate, and using a fifth target bending diameter that meets the third test end condition as a fifth limit bending diameter of the target type of plate; wherein the fourth determination operation includes: determining a fourth target bending diameter corresponding to the current fourth determination operation; wherein the fourth target bending diameter corresponding to the first fourth determination operation is the second limit bending diameter; based on the fourth target bending diameter, performing at least one fifth detection operation to obtain a third bent plate; the fifth detection operation is an operation of obtaining a plate to be tested of the target type, and determining the bending performance of the plate of the target type based on the plate to be tested; if the second surface of the third bent plate is cracked, and the fifth target bending diameter is equal to the second preset value, the fourth target bending diameter corresponding to the current fourth determination operation is increased to obtain a sixth bending diameter, and the sixth bending diameter is used as the fourth target bending diameter corresponding to the next fourth determination operation.

[0062] Further, in one embodiment, the fifth detection operation includes: obtaining a plate to be tested of a target type corresponding to the current fifth detection operation, and determining a fifth target bending diameter corresponding to the current fifth detection operation; wherein, in the first fourth determination operation, the fifth target bending diameter corresponding to the first fifth detection operation is the third limit bending diameter; in the fourth determination operation other than the first time, the fifth target bending diameter corresponding to the first fifth detection operation is determined based on the fourth target bending diameter; for a first bent plate that is flattened after being bent with the fourth target bending diameter, the first bending direction and the first bending angle, bend it with the fifth target bending diameter, the second bending direction and the third bending angle to obtain a third bent plate; the third bending angle is greater than the second bending angle; if the second surface of the third bent plate is cracked, and the fifth target bending diameter is less than the second preset value, the fifth target bending diameter corresponding to the current fifth detection operation is increased to obtain a seventh bending diameter, and the seventh bending diameter is used as the fifth target bending diameter corresponding to the next fifth detection operation.

[0063] Further, in one embodiment, the third test end condition is: there is no crack on the second surface of the third bent plate, and the fifth target bending diameter is less than or equal to the second preset value.

[0064] In the first fourth determination operation, the controller can determine that the fourth target bending diameter corresponding to the first fourth determination operation is the second limit bending diameter (for example: 2t, t is the thickness of the plate to be measured). Then in the first fourth determination operation, the plate to be measured of the target type corresponding to the first fifth detection operation is obtained, and the fifth target bending diameter corresponding to the first fifth detection operation is determined. At this time, the fifth target bending diameter is the third limit bending diameter (for example: 3t). The controller bends the first flattened plate that is flattened after bending with the fourth target bending diameter of 2t, the first bending direction (for example: positive bending) and the first bending angle (such as 90°) with the fifth target bending diameter of 3t, the second bending direction (for example: reverse bending) and the third bending angle (such as 180°) to obtain a third bent plate. Among them, the third bending angle is greater than the second bending angle. If there is no crack on the second surface of the third bent sheet, and the fifth target bending diameter 3t is less than or equal to the second preset value (e.g., 6t), the third test end condition is met, and the fourth target bending diameter 2t at this time is used as the fourth limit bending diameter of the target type of sheet, and the fifth target bending diameter 3t at this time is used as the fifth limit bending diameter of the target type of sheet. Specifically, when the target type of sheet is flattened in the first bending direction, i.e., forward bending, and the first bending angle is 90°, and when the second bending direction, i.e., reverse bending, and the third bending angle is 180°, the fourth limit bending diameter of the forward bending is the fourth target bending diameter 2t that meets the third test end condition, and the fifth limit bending diameter of the reverse bending is the fifth target bending diameter 3t that meets the third test end condition.

[0065] If the second surface of the third bent plate is cracked and the fifth target bending diameter 3t is less than the second preset value 6t, it is necessary to increase the fifth target bending diameter corresponding to the current fifth detection operation (the first fifth detection operation in the first fourth determination operation) to obtain the fifth bending diameter (for example: 4t). For example, the fifth bending diameter 4t is used as the fifth target bending diameter corresponding to the next fifth detection operation (the second fifth detection operation in the first fourth determination operation).

[0066] Then the controller bends the first flattened sheet, which is flattened after bending with the fourth target bending diameter of 2t, the first bending direction, i.e., positive bending, and the first bending angle of 90°, with the fifth target bending diameter of 4t, the second bending direction, i.e., reverse bending, and the third bending angle of 180°, to obtain a third bent sheet. If there is no crack on the second surface of the third bent sheet at this time, and the fifth target bending diameter of 4t is less than or equal to the second preset value of 6t, then the third test end condition is met, and the fourth limit bending diameter at this time is 2t, and the fifth limit bending diameter is 4t. If the third test end condition is still not met at this time, the fifth target bending diameter corresponding to the current fifth detection operation (the second fifth detection operation in the first fourth determination operation) is continued to be increased to obtain the seventh bending diameter (for example: 5t), and the seventh bending diameter of 5t is used as the fifth target bending diameter corresponding to the next fifth detection operation (the third fifth detection operation in the first fourth determination operation), and then based on the fourth target bending diameter of 2t and the fifth target bending diameter of 5t, the fifth detection operation is performed to see whether the third detection end condition is met...

[0067] If the second surface of the third bent sheet is cracked when the fourth target bending diameter is 2t and the fifth target bending diameter is 6t, and the fifth target bending diameter is equal to the second preset value 6t, the third test end condition is still not met. At this time, the fourth target bending diameter 2t corresponding to the current (first) fourth determination operation is increased to obtain the sixth bending diameter (for example: 3t), and the third bending diameter 3t is used as the fourth target bending diameter corresponding to the next (second) fourth determination operation. Then the controller determines the fifth target bending diameter corresponding to the current fifth detection operation (the first fifth detection operation in the second second determination operation). The fifth target bending diameter at this time is determined based on the fourth target bending diameter, and can be the same as the fourth target bending diameter, that is, 3t, that is, the fifth target bending diameter is 3t at this time. Then, the first flattened sheet flattened after bending with the fourth target bending diameter 3t, the first bending direction, i.e., positive bending, and the first bending angle of 90° is bent with the fifth target bending diameter 3t, the second bending direction, i.e., reverse bending, and the third bending angle of 180° to obtain a third bent sheet. If there is no crack on the second surface of the third bent sheet at this time, and the fifth target bending diameter 3t is less than or equal to the second preset value (e.g., 6t), the third test end condition is met, and the fourth limit bending diameter is 3t and the fifth limit bending diameter is 3t. If the third test end condition is still not met at this time, the fifth target bending diameter corresponding to the current fifth detection operation (the first fifth detection operation in the second fourth determination operation) is continued to be increased to obtain the seventh bending diameter (e.g., 4t), and the seventh bending diameter 4t is used as the fifth target bending diameter corresponding to the next fifth detection operation (the second fifth detection operation in the second fourth determination operation), and then based on the fourth target bending diameter 3t and the third target bending diameter 4t, the fifth detection operation is performed to see whether the third detection end condition is met... This process is repeated until the third test end condition is met.
