[0020] In the description of this application, "first feature" or "second feature" may include one or more of the features.

[0021] In the description of the present application, “plurality” means two or more.

[0022] In the description of the present application, a first feature being “on” or “under” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact with each other but are in contact with each other via another feature therebetween.

[0023] In the description of the present application, “above”, “over” and “above” a first feature to a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0024] refer to Figure 1 As shown, the steel bar bending device for building foundation construction includes a bracket 100, the bracket 100 is provided with a plurality of legs 110, and a guide plate 120 is provided at the top of the bracket 100. A guide member is provided on the guide plate 120; Figure 1In the corresponding example, the guide member is a roller 121, and the rollers 121 are spaced in pairs in the vertical direction and arranged in sequence in the horizontal direction, and then the rollers 121 spaced in the vertical direction can define a guide track extending in the horizontal direction. As shown in the figure, the rollers 121 include a first roller 1211, a second roller 1212, and a third roller 1213 arranged in sequence at the upper part of the figure in the horizontal direction, and a fourth roller 1214, a fifth roller 1215, a sixth roller 1216, and a seventh roller 1217 arranged in sequence at the lower part of the figure; and each roller 121 is constructed with a groove for matching with the outer surface of the steel bar.

[0025] Furthermore, each roller 121 can slide in a vertical direction, thereby changing the width of the guide track defined by the two rollers 121 .

[0026] The guide plate 120 is also provided with a clamping member 122 and a cutting blade 123 that fits with the clamping member 122 and reciprocates in the vertical direction. The clamping member 122 is integrally formed with the guide plate 120 and has a through slot 1221 thereon, which forms an extension area of ​​the guide track. Figure 1 As shown, the cutting blade 123 can move in a vertical direction to cut the steel bars transported to the through groove 1221, thereby completing the cutting function.

[0027] The guide plate 120 is also provided with a bending mechanism 124, which includes a fixed column 1241 provided on the extension area of ​​the guide track, and the peripheral wall of the fixed column 1241 is flush with the lower edge of the through groove 1221, so that the steel bar can be overlapped after the steel bar moves above it along the guide track. The bending mechanism 124 also includes a pressing block 1242 rotating around the fixed column 1241, and the pressing block 1242 presses and bends the steel bar by rotating after contacting the peripheral side of the steel bar to complete the bending function. In this example, the pressing block is driven by the telescopic arm 1243, and the telescopic arm 1243 is driven by the air pressure 1244, and the connecting pipeline between the air pressure 1244 and the telescopic arm 1243 is not shown in the figure.

[0028] It is understandable that the guide rail can also have a certain fixing effect on the steel bars, so that the steel bars remain in the guide rail and move along the guide rail for bending and cutting without the need for workers to fix or adjust the position of the steel bars using other tools.

[0029] That is to say, the steel bar bending device for building foundation construction in the embodiment of the present application can conveniently realize the bending function and the cutting function, so that steel bar cutting and bending can be realized based on one device, without the need to hold the bent steel bar in the hand to the cutting area for cutting (or vice versa, cut first and then bend), which can improve work efficiency.

[0030] Further integration Figure 2 As shown, the sixth roller 1216 is axially connected to the first drive shaft 132, and the drive shaft is used to drive the sixth roller 1216, so that the steel bar is continuously moved toward the clamping member 122 along the guide track through the friction between the sixth roller 1216 and the steel bar. The cutting blade 123 is rotatably connected to the connecting rod 1341, and the other end of the connecting rod 1341 is connected to the second drive shaft 133 through the crank mechanism 134. The second drive shaft 133 is used to drive the crank mechanism 134 to rotate, thereby driving the cutting blade 123 to reciprocate, thereby cutting the steel bar. The first drive shaft 132 and the second drive shaft 133 are both connected to the driver, so that the transportation and cutting of the steel bar are driven simultaneously by one driver, reducing the cost and control complexity.

[0031] And, if Figure 1 As shown, one end of the first drive shaft 132 is connected to the sixth roller 1216, and the other end is provided with a first gear 135; correspondingly, the second drive shaft 133 is provided with a fifth gear 139, and the driver is a motor 130, and a third gear 137 is provided on the output shaft 131 of the motor 130, and the third gear 137 and the first gear 135 are transmitted through the second gear 136, and the third gear 137 and the fifth gear 139 are transmitted through the fourth gear 138. Therefore, the speed ratio between the roller 121 and the crank mechanism 134 can be adjusted by setting the gear ratio between each gear, so that after the roller 121 conveys a certain length of steel bars, the cutting blade 123 cuts the steel bars, so that the length of the steel bars cut corresponds to the gear ratio, so as to obtain multiple steel bars of the same length. This can also reduce the construction time of workers and quickly cut fixed-length steel bars.

[0032] refer to Figure 3 , the third gear 137 is slidably arranged on the output shaft 131 of the motor 130, and the second gear 136 and the fourth gear 138 are staggered along the axis direction of the output shaft 131. As shown in the figure, the outer peripheral surface of the output shaft 131 is provided with an external spline 1312, and the third gear 137 is provided with a telescopic rod 1311 on the side facing the motor 130, and the telescopic rod 1311 is provided with an internal spline (not shown in the figure) on a part of the rod body close to the motor 130, so as to realize the power transmission and sliding connection between the output shaft 131 and the third gear 137.

[0033] That is, the third gear 137 can switch positions along the output shaft 131, thereby switching between meshing with the second gear 136 and meshing with the fourth gear 138. This enables the motor 130 to deliver power to the first gear 135 or the fifth gear 139 alone, thereby controlling the required length of the steel bar bending device.

[0034] For example, Figure 4In the state shown, the third gear 137 is first kept meshing with the second gear 136, and the sixth roller 1216 drives the steel bar to be continuously transported to the bending mechanism 124, and the bending mechanism 124 bends the steel bar according to the preset control parameters. When the user thinks that the bent steel bar is long enough, switch to Figure 5 In the state shown, the third gear 137 is meshed with the fourth gear 138, thereby driving the cutting blade 123 to cut the steel bar and complete the bending.

[0035] In order to realize the position switching of the third gear 137, the bracket 100 is further provided with an annular plate 140 surrounding the first gear 135, the second gear 136, the third gear 137, the fourth gear 138, and the fifth gear 139, and two guide grooves 141 extend from the annular plate 140; accordingly, a connecting rod 1371 extends from the center of the third gear 137, and the connecting rod 1371 bends toward the guide groove 141 to extend a strip plate 1372, and the ends of the strip plate 1372 are respectively slidably connected to the two guide grooves 141 to realize the position switching. The guide groove 141 can provide stability for the movement of the third gear 137.

[0036] Furthermore, a position sensor is also provided in the guide groove 141 to sense whether the strip plate 1372 has reached the target position. Figure 6 As shown, when the third gear 137 is meshed with the second gear 136, the position of the strip plate 1372 in the guide groove 141 is defined as the first position, and a first sensing point 1411 is provided at the first position; when the third gear 137 is meshed with the fourth gear 138, the position of the strip plate 1372 in the guide groove 141 is defined as the second position, and a second sensing point 1413 is provided at the second position; an intermediate sensing point 1412 is provided at any point between the first position and the second position, which is defined as the third position here.

[0037] The position sensor is used to receive electrical signals from the first sensing point 1411, the second sensing point 1413, and the middle sensing point 1412. When it receives the electrical signal from the middle sensing point 1412, it outputs a stop command to the motor 130; when the first sensing point 1411 or the second sensing point 1413 receives a signal, it outputs a start command to the motor 130.

[0038] It is understandable that, during the process of position switching of the third gear 137, even if the third gear 137 switches from the meshing state with the second gear 136 to the meshing state with the fourth gear 138 (or vice versa), the third gear 137 must be stopped first to prevent the gears from being damaged by collision. Therefore, when the third gear 137 moves to the position between the second gear 136 and the fourth gear 138, it means that switching is required, that is, when the third gear 137 is in the third position, the motor 130 should be stopped to achieve position switching.

[0039] In addition, according to any of the above specific examples, the second gear 136 and the third gear 137 and the fourth gear 138 can all be constructed as helical gears to facilitate engagement and separation.

[0040] Therefore, the user can cut a certain amount of bent steel bars by switching the position of the third gear 137 as needed, which is convenient for user operation and improves the efficiency of obtaining bent steel bars.

[0041] According to a control method of an embodiment of the present application, it is used to control the steel bar bending device for building foundation construction in the above embodiment, referring to Figure 7 As shown, it includes: switching the third gear 137 to a position engaged with the second gear 136 (i.e., the first position). At this time, the position sensor receives the electrical signal of the first sensing point 1411 to output a start command to the motor 130, and the motor 130 starts to run, driving the sixth roller 1216 to rotate through gear transmission, and then friction drives the steel bar to move along the guide track toward the bending mechanism 124.

[0042] Correspondingly, the bending mechanism 124 bends the steel bar according to the preset control parameters. When the user determines that the steel bar is bent to the required length, the user stops inputting the bending instruction to the bending mechanism 124 (such as set by the control system), so that the steel bar is no longer bent.

[0043] Then, the third gear 137 is gradually moved from the meshing state with the second gear 136 to the middle position (ie, the third position). To make the transition smooth, the third gear 137 and the second gear 136 can be set as helical gears, thereby smoothly separating the third gear 137 from the second gear 136.

[0044] When the third gear 137 moves to the middle position, the position sensor receives the electrical signal from the middle sensing point 1412 and outputs a stop command to the motor 130, so that the motor 130 stops running.

[0045] The third gear 137 is switched from the middle position to the position (ie, the second position) meshing with the fourth gear 138 manually or through an auxiliary mechanism. At this time, the position sensor receives the electrical signal of the second sensing point 1413 .

[0046] In some specific examples, after the second sensing point 1413 receives the electrical signal, the control system for controlling the motor 130 will send a start command with a delay after receiving the result that the second sensing point 1413 receives the electrical signal, so as to prevent the third gear 137 from starting to rotate when the third gear 137 and the fourth gear 138 are not fully engaged.

[0047] When the third gear 137 is meshed with the fourth gear, the motor 130 starts to operate, driving the crank mechanism 134 to rotate through gear transmission, thereby driving the cutting blade 123 to reciprocate and cut the steel bar.
