[0002] As an important cornerstone of the construction industry, steel bars, with their unique round or rounded square cross-section, play a vital role in strengthening concrete structures, improving tensile strength and earthquake resistance. Especially in the foundation construction of buildings, the addition of steel bars greatly enhances the stability and bearing capacity of the foundation, effectively preventing the risk of foundation settlement and damage.

[0029] The present invention will be further described below in conjunction with the embodiments.

[0030] Embodiment: A steel bar bending device used in a construction site, such as Figure 1-Figure 9 As shown, it includes a base 1, which plays a supporting role and can be fixedly installed in a suitable position by bolts to facilitate the bending of steel bars; and a bearing frame 3 fixedly installed on the upper surface of the base 1, which is used to place the steel bars to be bent; a groove 301 is provided on the lower surface of the bearing frame 3, and the inner wall of the groove 301 is connected to a slide groove provided on the surface of the bearing frame 3, and the groove 301 and the slide groove are provided to play a guiding and limiting role; a clamping plate 302 is provided on the upper surface of the bearing frame 3, and the clamping plate 302 is slidably matched with the surface of the bearing frame 3, and the clamping plate 302 is provided, so that the steel bars to be bent can be clamped, ensuring that the steel bars are in a stable state during the bending process;

[0031] It also includes a hollow disk 2 fixedly mounted on the upper surface of the base 1, a matching rod 201 is fixedly mounted on the upper end of the hollow disk 2, and the axis of the matching rod 201 is provided with a through hole connected to the inside of the hollow disk 2. By setting the matching rod 201, it can contact the steel bar to be bent, so that the steel bar can be bent with the matching rod 201 as the center; a limiting groove 202 is provided through the surface of the hollow disk 2, and the limiting groove 202 is a semi-arc structure, which can play a guiding and limiting role; a plurality of groups of clamping grooves 203 are equidistantly provided on the bottom surface of the limiting groove 202, and by providing the clamping grooves 203, the bending angle of the steel bar can be controlled to ensure that each bending of the steel bar is at the same angle, thereby achieving the purpose of high-quality bending; it is worth noting that the angle between each two adjacent groups of clamping grooves 203 can be set as needed.

[0032] Combined with Figure 1 -Attached Fig. 9 , by setting an adjustment mechanism 4 for improving the bending accuracy of the steel bars, it is possible to ensure that the bending angle of each steel bar is consistent when the steel bars are bent, thereby ensuring the bending accuracy and efficiency of the steel bars; the adjustment mechanism 4 includes a clamping block 401 clamped with the clamping slot 203, and by setting the clamping block 401, it can be clamped and matched with multiple groups of clamping slots 203 to adjust the bending angle of the steel bars, thereby ensuring that the bending angles of the steel bars are consistent; a connecting rod 402 is fixedly installed at one end of the clamping block 401 close to the axis of the hollow disk 2, and by setting the connecting rod 402, it can play a connecting role;

[0033] Among them, a cylinder 403 is fixedly installed on the surface of the connecting rod 402, and the cylinder 403 is arranged in the through hole, and the cylinder 403 is rotatably connected to the through hole. By setting the cylinder 403, the block 401 fixedly connected to the connecting rod 402 can be driven to move synchronously through its actions, such as lifting and rotating actions; a connecting spring is sleeved on the surface of the cylinder 403, and the two ends of the connecting spring are rotatably connected to the upper surface of the connecting rod 402 and the inner wall of the hollow disk 2. By setting the connecting spring, the connecting rod 402 that is in action can be driven to reset through the characteristics of the reaction force generated when it is deformed; it is worth noting that the connecting spring realizes the rotation connection through parts in the prior art, such as ball bearings and other parts;

[0034] The surface of the cylinder 403 is slidably connected with a pointer 4031, and the pointer 4031 is installed in a staggered manner with the block 401. Figure 4, pointer 4031 points to the center position of the slot 203, and the slot 203 pointed to by pointer 4031 is located below the slot 203 engaged with the block 401; through the staggered installation of pointer 4031 and the block 401, it is possible to ensure that the bending angle of the steel bar can reach the angle pointed by pointer 4031 when the steel bar is bent, and at the same time, pointer 4031 slides with cylinder 403, so that when the cylinder 403 moves upward, it will not drive pointer 4031 to move synchronously; a degree indicator disk fixedly installed on the upper surface of the hollow disk 2 is provided below the pointer 4031, and the degree indicator disk is a prior art and is not shown in the figure, so as to cooperate with pointer 4031 to adjust the bending angle of the steel bar and ensure that the angle is consistent when the steel bar is bent; a knob 404 is fixedly installed on the upper end of the cylinder 403, and the cylinder 403 can be controlled to move by setting the knob 404.

[0035] The surface of the hollow disk 2 is rotatably connected with a collar 5, and a force-applying handle 501 is fixedly installed on the outer arc surface of the collar 5. By setting the collar 5 and the force-applying handle 501, it can be ensured that the force-applying handle 501 can drive the collar 5 to rotate with the hollow disk 2 as the axis; the surface of the force-applying handle 501 is fixedly installed with an adjustable bending member 502, and the bending member 502 is provided to facilitate adjusting the position according to different specifications of steel bars to achieve bending of the steel bars; the bending member 502 includes a strip plate 5021 fixedly installed on the surface of the force-applying handle 501, and the strip plate 5021 can play a guiding and limiting role;

[0036] The strip plate 5021 is internally slidably matched with a bending rod 5022, and by setting the bending rod 5022, it can cooperate with the matching rod 201 to achieve bending of the steel bar; the lower end of the bending rod 5022 is meshedly connected with a screw rod 5023 with one end rotatably connected to the force applying handle 501, and by setting the screw rod 5023, the position of the bending rod 5022 can be adjusted by rotating it; a turntable 5024 is fixedly installed on the other end of the screw rod 5023, and the strip plate 5021 can be used to drive the screw rod 5023 to rotate; a convex rod 503 is fixedly installed on the inner arc surface of the ring 5, and the convex rod 503 is arranged inside the limiting groove 202 and slidably matched with the limiting groove 202, and by setting the convex rod 503, when the force applying handle 501 drives the ring 5 to rotate, the convex rod 503 will be driven to slide inside the bending member 502 until it contacts the clamping block 401, thereby achieving bending of the steel bar at a fixed angle.

[0037] Combined with Figure 1 -Attached Fig. 9, and also includes a stabilizing mechanism 6 for fixing the steel bar when it is bent, so as to ensure that the steel bar is in a stable state during the bending process, avoid manual fixation, and speed up the bending efficiency of the steel bar; the stabilizing mechanism 6 includes a gear ring 601, and the gear ring 601 is fixedly installed on the upper end of the sleeve ring 5, and by setting the gear ring 601, it can rotate synchronously with the sleeve ring 5; one side of the gear ring 601 is meshingly connected with a driven disk 602, and the upper end of the driven disk 602 is movably connected with a gear 603, and by setting the driven disk 602 and the gear 603, it can rotate synchronously when the gear ring 601 rotates; it is worth mentioning that the gear 603 is inserted into the inside of the driven disk 602, and is fixed by the friction between the two in a state without force. When the driven disk 602 drives the gear 603 to rotate, the gear 603 is subject to large resistance, and the gear 603 will not rotate, and the driven disk 602 rotates alone;

[0038] The gear 603 is meshed with a rack 604, and the rack 604 is provided to enable lateral movement under the action of the gear 603; a horizontal plate 605 is fixedly installed on the upper surface of the rack 604, and the horizontal plate 605 is provided to guide the rack 604; the rack 604 and the horizontal plate 605 are both arranged inside the groove 301, and the horizontal plate 605 is slidably matched with the inner wall of the groove 301, and one end of the horizontal plate 605 is connected to the groove 301 by a reset spring 6051. The inner wall of the groove 301 is elastically connected, and a reset spring 6051 is set, so that when the rack 604 and the cross plate 605 move laterally, their deformation can be driven to generate a reaction force, so that the rack 604 and the cross plate 605 can be reset laterally after the lateral movement; a slider is fixedly installed on the upper end of the cross plate 605, and the slider penetrates the slide groove and is fixedly connected to the clamping plate 302. By setting a slider, the cross plate 605 can be fixedly connected to the clamping plate 302 to achieve the purpose of synchronous movement.

[0039] Specifically, when bending the steel bar, the steel bar is first placed between the clamping plate 302 and the matching rod 201, and then according to the angle at which the steel bar needs to be bent, the knob 404 is first lifted upward to separate the clamping block 401 from the clamping slot 203, and then the knob 404 is rotated, so that the cylinder 403 drives the pointer 4031 to start rotating, until the pointer 4031 points to the required bending angle of the steel bar on the degree indicator, the knob 404 is released, and the clamping block 401 enters the clamping slot 203 directly below it under the action of the connecting spring; then, according to the specifications of the steel bar, the strip plate 5021 is rotated to make the screw rod 5023 rotate to start adjusting the position of the bending rod 5022, and when the position adjustment of the bending rod 5022 is completed, the force application handle 501 is rotated to make the collar 5 drive the convex rod 503 to start sliding inside the limiting groove 202;

[0040] When the ring 5 rotates, the gear ring 601 fixed on its upper end will also rotate synchronously, and then it will start to drive the driven plate 602 meshing with it to rotate synchronously, and then drive the rack 604 meshing with it to start to move horizontally through the gear 603, so that the cross plate 605 drives the clamping plate 302 to start to move horizontally in the direction of the matching rod 201 and stretch the reset spring 6051, so as to achieve the fixation of the steel bar; after the steel bar is fixed, resistance will be generated between the gear 603 and the rack 604, and as the force application handle 501 continues to rotate, the driven plate 602 starts to overcome the friction between it and the gear 603, and then starts to rotate independently;

[0041] The continuous rotation of the force-applying handle 501 will drive the bending rod 5022 to start cooperating with the matching rod 201 to bend the steel bar. When the protruding rod 503 comes into contact with the clamping block 401, the bending of the steel bar is completed, so that each bending of the steel bar has the same bending angle. After the bending of the steel bar is completed, the force-applying handle 501 is controlled to rotate in the opposite direction and reset. During the reverse rotation, the driven plate 602 will be driven to rotate in the opposite direction through the gear ring 601, and the gear 603 will also start to rotate in the opposite direction, thereby driving the rack 604 and the cross plate 605 to move in the opposite direction synchronously, and driving the clamping plate 302 to start separating from the steel bar, so as to facilitate the replacement of the steel bar.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
