[0069] Stirrup bending machines are the most widely used steel bar equipment. At present, most of the stirrup bending machines have inaccurate bending angles when bending steel bars, and angle compensation needs to be repeated many times, resulting in low equipment efficiency, waste of manpower and material costs, etc. When the equipment is in batches, the bending coordinate positions are inconsistent, resulting in the overall offset of the bending angle coordinates, and the accuracy of the equipment needs to be improved.

[0070] How to improve the accuracy of the bending angle of the steel bars bent by the hoop bending machine has become a problem that needs to be solved urgently.

[0071] Based on the above problems, an embodiment of the present application provides a method for controlling the bending angle of steel bars, which obtains the straight side length of the guide groove and the radius length of the guide groove in the hoop bending machine; based on the relationship between the straight side length of the guide groove and the radius length of the guide groove, the first angle between the target steel bar and the guide groove after the target steel bar is bent to a target bending angle is calculated, thereby ensuring the accuracy of the calculated first angle. Based on the first angle and the target bending angle, the target rotation angle of the bending wheel in the hoop bending machine is calculated, thereby ensuring the accuracy of the calculated target rotation angle. Based on the target rotation angle, the bending wheel is positioned to obtain the target steel bar at the target bending angle, thereby improving the accuracy of the bending angle of the steel bars bent by the hoop bending machine. There is no need to perform angle compensation repeatedly, thereby improving equipment efficiency and saving manpower and material costs.

[0072] It should be noted that the method for controlling the bending angle of steel bars provided in the embodiment of the present application may be executed by a device for controlling the bending angle of steel bars, which may be implemented as part or all of an electronic device through software, hardware, or a combination of software and hardware, wherein the electronic device may be a server or a terminal, wherein the server in the embodiment of the present application may be a single server or a server cluster composed of multiple servers, and the terminal in the embodiment of the present application may be a smart phone, a personal computer, a tablet computer, a wearable device, an intelligent robot, or other intelligent hardware devices. In the following method embodiments, the execution subject is an electronic device as an example for explanation.

[0073] According to an embodiment of the present invention, an embodiment of a method for controlling a bending angle of a steel bar is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0074] In this embodiment, a method for controlling the bending angle of a steel bar is provided, which can be used in the above-mentioned electronic device. Figure 1 : is a flow chart of a method for controlling a steel bar bending angle according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0075] Step S101, obtaining the straight side length and radius length of the guide groove in the hoop bending machine.

[0076] Specifically, the electronic device can receive the straight side length and the radius length of the guide groove in the hoop bending machine input by the user, and can also receive the straight side length and the radius length of the guide groove in the hoop bending machine sent by other devices, and can also search for the straight side length and the radius length of the guide groove in the hoop bending machine in the storage space.

[0077] The embodiment of the present application does not specifically limit the manner in which the electronic device obtains the straight side length and the radius length of the guide groove in the hoop bending machine.

[0078] Step S102, calculating a first angle between the target steel bar and the guide groove after the target steel bar is bent to a target bending angle according to the relationship between the straight side length of the guide groove and the radius length of the guide groove.

[0079] Specifically, the electronic device may add the radius length of the guide groove to the width between the two guide grooves to obtain the first distance, and add the radius length of the guide groove to the target steel bar diameter to calculate the second distance.

[0080] Then, according to the relationship between the straight side length of the guide groove, the first distance and the second distance, a first angle between the target steel bar and the guide groove after the target steel bar is bent to a target bending angle is calculated.

[0081] This step will be described in detail below.

[0082] Step S103, calculating the target rotation angle of the bending wheel in the hoop bending machine according to the first angle and the target bending angle.

[0083] Specifically, the electronic device can obtain a fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves and a sixth distance from the center point of the guide groove to the vertical center line of the guide groove.

[0084] Then, according to the relationship between the sixth distance, the fifth distance and the first angle, the target rotation angle of the bending wheel in the hoop bending machine is calculated.

[0085] This step will be described in detail below.

[0086] Step S104, positioning the bending wheel according to the target rotation angle to obtain the target steel bar with the target bending angle.

[0087] Specifically, after the target rotation angle of the bending wheel is calculated, the electronic device can position the bending wheel according to the target rotation angle, thereby obtaining a target steel bar with a target bending angle.

[0088] The steel bar bending angle control method provided in the embodiment of the present application obtains the straight side length of the guide groove and the radius length of the guide groove in the hoop bending machine; based on the relationship between the straight side length of the guide groove and the radius length of the guide groove, the first angle between the target steel bar and the guide groove after the target steel bar is bent to the target bending angle is calculated, thereby ensuring the accuracy of the calculated first angle. Based on the first angle and the target bending angle, the target rotation angle of the bending wheel in the hoop bending machine is calculated, thereby ensuring the accuracy of the calculated target rotation angle. Based on the target rotation angle, the bending wheel is positioned to obtain the target steel bar of the target bending angle, thereby improving the accuracy of the bending angle of the steel bars bent by the hoop bending machine. There is no need to perform angle compensation repeatedly, thereby improving equipment efficiency and saving manpower and material costs.

[0089] In this embodiment, a method for controlling the bending angle of a steel bar is provided, which can be used in the above-mentioned electronic device. Figure 2 : is a flow chart of a method for controlling a steel bar bending angle according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0090] Step S201, obtaining the straight side length and radius length of the guide groove in the hoop bending machine.

[0091] For details about this step, please refer to the above description of step S101, which will not be elaborated here.

[0092] Step S202, based on the relationship between the straight side length of the guide groove and the radius length of the guide groove, calculate the first angle between the target steel bar and the guide groove after the target steel bar is bent to a target bending angle.

[0093] Specifically, the above step S202 may include the following steps:

[0094] Step S2021 adds the radius length of the guide groove and the width between the two guide grooves to obtain a first distance.

[0095] Specifically, the electronic device may add the radius length of the guide groove and the width between two guide grooves to obtain the first distance.

[0096] For example, Figure 3 As shown, Figure 3 The two green ovals are the two guide grooves in the hoop bending machine, the blue part is the target steel bar, and the green circle is the bending wheel. The target steel bar is bent to the target bending angle by rotating the bending wheel around the first intersection point between the vertical center line and the horizontal center line between the two guide grooves. Figure 3 In the figure, the radius length of the guide groove is L1, and the radius length of the guide groove is added to the width between two guide grooves to obtain a first distance, which is L4.

[0097] Step S2022, adding the radius length of the guide groove to the target steel bar diameter to calculate the second distance.

[0098] Specifically, the electronic device adds the radius length of the guide groove to the target steel bar diameter to calculate the second distance.

[0099] For example, Figure 3 As shown in the figure, the radius of the guide groove is added to the target steel bar diameter to calculate the second distance, which is Figure 3 L5 in.

[0100] Step S2023, calculating a fourth distance from the edge of the target steel bar to the intersection of the straight side and the curved side of the guide groove according to the trigonometric function relationship between the straight side length of the guide groove and the first distance and the second distance.

[0101] Specifically, Figure 3 As shown, the right triangle where L1 is located is similar to the right triangle where L5 is located. According to the principle of triangle similarity, we can get L1 / L5=L2 / (L4-L3). According to the Pythagorean theorem of right triangles, we can get L3 2 +L12=L22.

[0102] Therefore, the electronic device can calculate the fourth distance from the edge of the target steel bar to the intersection of the straight edge and the curved edge of the guide groove. Figure 3 L3 in.

[0103] Step S2024: Calculate the first angle based on the functional relationship between the straight side length of the guide groove and the fourth distance.

[0104] Specifically, Figure 3 As shown, according to the functional relationship of the right triangle, Tanα4=L1 / L3, so the electronic device calculates the first angle, that is, Figure 3 α4 in.

[0105] Step S203, calculating the target rotation angle of the bending wheel in the hoop bending machine according to the first angle and the target bending angle.

[0106] Specifically, the above step S203 may include:

[0107] Step S2031, obtaining a fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves and a sixth distance from the center point of the guide groove to the vertical center line of the guide groove.

[0108] Specifically, the electronic device can receive the fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves and the sixth distance from the center point of the guide groove to the vertical center line of the guide groove input by the user, and can also receive the fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves and the sixth distance from the center point of the guide groove to the vertical center line of the guide groove sent by other devices, and also search the fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves and the sixth distance from the center point of the guide groove to the vertical center line of the guide groove from the storage space.

[0109] The embodiment of the present application does not specifically limit the manner in which the electronic device obtains the fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves and the sixth distance from the center point of the guide groove to the vertical center line of the guide groove.

[0110] For example, Figure 4 As shown, the fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves is L7, and the sixth distance from the center point of the guide groove to the vertical center line of the guide groove is L6.

[0111] Step S2032, based on the functional relationship between the fifth distance and the sixth distance, calculate the seventh distance from the center of the guide groove to the first intersection of the horizontal center line and the vertical center line between the two guide grooves and the second angle between the seventh distance and the fifth distance.

[0112] Specifically, Figure 4As shown, the seventh distance from the center of the guide groove to the first intersection of the horizontal center line and the vertical center line between the two guide grooves is L8. The second angle between the seventh distance and the fifth distance is α1. According to the right triangle function relationship, Tanα1=L6 / L7, L82=L62+L72. Therefore, the electronic device calculates the seventh distance from the center of the guide groove to the first intersection of the horizontal center line and the vertical center line between the two guide grooves, i.e., L8, and the second angle between the seventh distance and the fifth distance, i.e., α1, according to the above trigonometric function formula.

[0113] Step S2033, calculating the target rotation angle of the bending wheel in the hoop bending machine according to the relationship between the second angle, the first angle and the seventh distance.

[0114] Specifically, the above step S2033 may include the following steps:

[0115] Step a1, passing through the first intersection between the vertical center line and the horizontal center line between the two guide grooves, and making a first straight auxiliary line along the reverse extension line direction of the target steel bar.

[0116] Specifically, Figure 4 As shown, the electronic device passes through the first intersection between the vertical center line and the horizontal center line between the two guide grooves, and makes a first straight auxiliary line along the reverse extension line direction of the target steel bar.

[0117] Step a2, passing through the first intersection, and making a second curved and straight auxiliary line along the bending direction of the target steel bar with a constant distance from the edge of the target steel bar.

[0118] Specifically, Figure 4 As shown, the electronic device passes through the first intersection and draws a second curved and straight auxiliary line along the bending direction of the target steel bar with a constant distance from the edge of the target steel bar.

[0119] Step a3, make the second straight line and combine it with the reverse extension line of the lower straight line of the auxiliary line to obtain the third straight line auxiliary line.

[0120] Specifically, Figure 4 As shown, the electronic device makes a second curved and straight line by combining the reverse extension line of the lower straight line of the auxiliary line to obtain a third straight auxiliary line.

[0121] Step a4, based on the trigonometric relationship between the second angle, the first angle and the seventh distance, calculate the eighth distance from the center of the guide groove to the first straight line auxiliary line, and determine the intersection between the eighth distance and the first straight line auxiliary line as the second intersection.

[0122] Specifically, Figure 5 for Figure 4 A partial enlarged view of Figure 5Combination Figure 3 As shown, Figure 5 α2=90-α1-α4, according to the trigonometric relationship, L16=L8*Sinα2. Therefore, L16=L8*Sin(90-α1-α4). Therefore, the electronic device calculates the eighth distance between the center of the guide groove and the first straight line auxiliary line according to the trigonometric relationship between the second angle, the first angle, and the seventh distance, that is, Figure 5 L8 in.

[0123] Step a5, calculating a ninth distance between the first intersection point and the second intersection point according to a trigonometric function relationship among the second angle, the first angle and the seventh distance.

[0124] Specifically, Figure 5 Combination Figure 3 As shown, Figure 5 α2=90-α1-α4, according to the trigonometric relationship. In the right triangle where L8 and L9 are located, L9=L8*COSα2, therefore. L9=L8*COS(90-α1-α4). Therefore, the electronic device calculates the ninth distance between the first intersection and the second intersection according to the trigonometric relationship between the second angle, the first angle and the seventh distance, that is, Figure 5 L9 in.

[0125] Step a6, calculating the tenth distance according to the relationship between the eighth distance and the target bending angle; the tenth distance represents the distance from the second intersection point to the third intersection point between the third straight line auxiliary line and the first straight line auxiliary line.

[0126] Specifically, the electronic device determines the intersection point between the third straight line auxiliary line and the first straight line auxiliary line as the third intersection point, and determines the distance from the second intersection point to the third intersection point as the tenth distance. Figure 5 Combination Figure 3 As shown, the tenth distance is L10. Wherein θ is the target bending angle. According to the relationship between congruent triangles and trigonometric functions, the electronic device determines that the tenth distance = the eighth distance / Tan ((180-target bending angle) / 2), that is, L10 = L16 / Tan ((180-θ) / 2.

[0127] Step a7, calculating the target rotation angle of the bending wheel in the hoop bending machine according to the relationship among the eighth distance, the ninth distance and the tenth distance.

[0128] Specifically, the above step a7 may include the following steps:

[0129] Step a71, calculating the target complementary angle corresponding to the target bending angle.

[0130] Specifically, the electronic device can calculate the target complementary angle corresponding to the target bending angle by subtracting the target bending angle from 180 degrees.

[0131] like Figure 6 As shown, Figure 6 The target complementary angle is α3.

[0132] Step a72, adding the second distance to the bending wheel radius minus the eighth distance to obtain the eleventh distance.

[0133] The eleventh distance is used to characterize the distance between the center of the bending wheel and the second curved-straight auxiliary line.

[0134] Specifically, the electronic device adds the second distance to the bending wheel radius and subtracts the eighth distance to obtain the eleventh distance.

[0135] For example, Figure 6 As shown, the second distance minus the eighth distance is the distance from the second curved-straight auxiliary line to the upper edge of the target steel bar. The distance from the second curved-straight auxiliary line to the upper edge of the target steel bar plus the radius of the bending wheel is used to obtain the eleventh distance, that is, Figure 6 L12 in.

[0136] Step a73, calculating the twelfth distance according to the trigonometric function relationship between the eleventh distance and the target complementary angle.

[0137] Among them, the twelfth distance is used to characterize the distance from the center of the bending wheel to the fourth intersection of the fourth straight auxiliary line and the second straight-curved auxiliary line; the fourth straight auxiliary line is an auxiliary line passing through the center of the bending wheel and parallel to the first straight auxiliary line.

[0138] Specifically, the electronic device makes a fourth straight line auxiliary line parallel to the first straight line auxiliary line through the center of the bending wheel, and determines the intersection of the fourth straight line auxiliary line and the second straight-curved auxiliary line as the fourth intersection point.

[0139] Then, the electronic device calculates the twelfth distance between the center of the bending wheel and the fourth intersection point according to the trigonometric function relationship between the eleventh distance and the target complementary angle, ie, the twelfth distance=the eleventh distance / sin target complementary angle.

[0140] Specifically, Figure 6 As shown, L11 = L12 / sinα3. Therefore, the electronic device calculates the twelfth distance, that is, Figure 6 L11 in.

[0141] Step a74, calculating the target rotation angle of the bending wheel in the hoop bending machine according to the trigonometric function relationship between the eleventh distance and the twelfth distance.

[0142] Specifically, the above step a74 may include the following steps:

[0143] Step a741, connecting the first intersection point and the center of the bending wheel to obtain a fifth line segment auxiliary line; and obtaining a preset distance corresponding to the fifth line segment auxiliary line.

[0144] Specifically, the electronic device connects the first intersection point and the center of the bending wheel to obtain the fifth line segment auxiliary line. The electronic device can receive the preset distance corresponding to the fifth line segment auxiliary line input by the user, or receive the preset distance corresponding to the fifth line segment auxiliary line sent by other devices.

[0145] Step a742, determining the intersection point between the fifth line segment auxiliary line and the second curved-straight combined auxiliary line as the fifth intersection point.

[0146] Specifically, the electronic device determines the intersection point between the fifth line segment auxiliary line and the second curved-straight combined auxiliary line as the fifth intersection point.

[0147] Step a743, the relationship between the twelfth distance, the ninth distance, the tenth distance and the preset distance, calculate the thirteenth distance between the first intersection point and the fifth intersection point and the fourteenth distance between the fifth intersection point and the center of the bending wheel;

[0148] Specifically, Figure 6 As shown, the triangle where the twelfth distance and the thirteenth distance are located is similar to the triangle where the fourteenth distance and the sum of the ninth distance and the tenth distance are located.

[0149] Therefore, according to the similar triangle function relationship, the electronic device determines that (L9+L10) / L11=L14 / L13, and L13+L14=the preset distance corresponding to the fifth line segment auxiliary line.

[0150] For example, L13+L14=80, (L9+L10) / L11=L14 / L13, therefore, the electronic device can calculate the thirteenth distance between the first intersection point and the fifth intersection point, that is, Figure 6 L13 in the figure, and calculate the fourteenth distance between the fifth intersection point and the center of the bending wheel, that is, Figure 6 L14 in.

[0151] Step a744, calculate the target rotation angle of the bending wheel in the hoop bending machine based on the thirteenth distance and the fourteenth distance.

[0152] Specifically, the above step a744 may include the following steps:

[0153] Step a7441, calculating the fifteenth distance between the fifth intersection point and the first straight auxiliary line according to the trigonometric function relationship between the fourteenth distance and the sum of the distances between the ninth distance and the tenth distance;

[0154] Specifically, Figure 6 As shown, in the triangle where the fourteenth distance and the sum of the ninth distance and the tenth distance are located, according to the trigonometric function relationship:

[0155] L152+(L9+L10)2-L14 2 -2xL15x(L9+L10)cos(180-θ)=0;

[0156] The electronic device can calculate the fifteenth distance between the fifth intersection point and the first straight auxiliary line, that is, Figure 6 L15 in.

[0157] Step a7442, based on the trigonometric function relationship between the fifteenth distance and the sum of the distances between the ninth distance and the tenth distance, calculate the third angle between the fifth line segment auxiliary line and the first straight line auxiliary line.

[0158] Specifically, Figure 6 As shown, the electronic device calculates the trigonometric relationship between the fifteenth distance and the distance between the ninth distance and the tenth distance, L14 2 +(L9+L10)2-L152-2xL14x(L9+L10)cosβ=0, the third angle between the fifth line segment auxiliary line and the first straight line auxiliary line can be calculated, that is Figure 6 β in .

[0159] Step a7443, use the third angle plus the first angle to calculate the target rotation angle.

[0160] Specifically, the electronic device calculates the target rotation angle by adding the third angle to the first angle.

[0161] like Figure 7 As shown, Figure 7 The γ in is the target rotation angle.

[0162] Step S204, positioning the bending wheel according to the target rotation angle to obtain the target steel bar with the target bending angle.

[0163] For details about this step, please refer to the above description of step S104, which will not be described in detail here.

[0165] Then, the fifth distance from the center point of the guide groove to the horizontal center line between the two guide grooves and the sixth distance from the center point of the guide groove to the vertical center line of the guide groove are obtained; based on the functional relationship between the fifth distance and the sixth distance, the seventh distance from the center point of the guide groove to the first intersection of the horizontal center line and the vertical center line between the two guide grooves and the second angle between the seventh distance and the fifth distance are calculated to ensure the accuracy of the calculated seventh distance and the second angle.

[0166] Through the first intersection between the vertical center line and the horizontal center line between the two guide grooves, make a first straight auxiliary line in the direction of the reverse extension line of the target steel bar; through the first intersection, make a second straight and curved auxiliary line along the bending direction of the target steel bar with a constant distance from the edge of the target steel bar; make a reverse extension line of the middle and lower straight line of the second straight and curved auxiliary line to obtain a third straight auxiliary line; according to the trigonometric relationship between the second angle, the first angle and the seventh distance, calculate the eighth distance between the center of the guide groove and the first straight auxiliary line, and determine the intersection between the eighth distance and the first straight auxiliary line as the second intersection, thereby ensuring the accuracy of the calculated eighth distance. According to the trigonometric relationship between the second angle, the first angle and the seventh distance, calculate the ninth distance between the first intersection and the second intersection, thereby ensuring the accuracy of the obtained ninth distance. According to the relationship between the eighth distance and the target bending angle, calculate the tenth distance, thereby ensuring the accuracy of the calculated tenth distance.

[0167] Calculate the target complementary angle corresponding to the target bending angle; add the bending wheel radius to the second distance minus the eighth distance to obtain the eleventh distance; the eleventh distance is used to characterize the distance between the center of the bending wheel and the second curved-straight auxiliary line; calculate the twelfth distance based on the trigonometric function relationship between the eleventh distance and the target complementary angle, thereby ensuring the accuracy of the calculated twelfth distance.

[0168] Connect the first intersection and the center of the bending wheel to obtain the fifth line segment auxiliary line; and obtain the preset distance corresponding to the fifth line segment auxiliary line; determine the intersection between the fifth line segment auxiliary line and the second straight-curved auxiliary line as the fifth intersection; calculate the relationship between the twelfth distance, the ninth distance, the tenth distance and the preset distance, calculate the thirteenth distance between the first intersection and the fifth intersection and the fourteenth distance between the fifth intersection and the center of the bending wheel, and ensure the accuracy of the calculated thirteenth distance and fourteenth distance.

[0169] According to the trigonometric relationship between the fourteenth distance and the sum of the distances between the ninth distance and the tenth distance, the fifteenth distance between the fifth intersection and the first straight line auxiliary line is calculated, which ensures the accuracy of the calculated fifteenth distance. According to the trigonometric relationship between the fifteenth distance and the sum of the distances between the ninth distance and the tenth distance, the third angle between the fifth line segment auxiliary line and the first straight line auxiliary line is calculated, which ensures the accuracy of the calculated third angle. The target rotation angle is calculated by adding the third angle to the first angle, which ensures the accuracy of the calculated target rotation angle.
