Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a steel bar bending device used in building construction. Background Technology

[0002] In the construction industry, it is often necessary to bend steel bars into various required curves or shapes. A search revealed that application number "CN202022518183.X" discloses "A mobile steel bar bending device for construction," which describes how "rotating the rotating rod drives the limiting rod upward, causing the limiting rod to engage in the limiting groove on the turntable, thus fixing the position of the two horizontal plates. After the steel bar is fixed, the hydraulic press can be started to bend it. This utility model has a simple structure, is easy to use, facilitates steel bar bending, and reduces bending errors." While it utilizes the principle of rotating the rotating rod to drive the limiting rod upward, causing it to engage in the limiting groove on the turntable to fix the position of the two horizontal plates, and allows bending of the steel bar by starting the hydraulic press after fixing it, this application does indeed facilitate steel bar bending and reduce bending errors.

[0027] Example

[0028] Please see Figures 1-5 A steel bar bending device for building construction includes a support box 100, an adjustment component 200, and a protection component 300.

[0029] Please refer to the details. Figure 1 A circular groove is provided at the top of the inner wall of the support box 100, and a support column 110 is provided at the bottom of the inner wall of the support box 100.

[0030] Please see Figure 3-4 The adjustment assembly 200 includes a connecting plate 210 disposed on the top of the support column 110. The inner wall of the connecting plate 210 is provided with two limiting plates 220. The inner walls of the two limiting plates 220 are slidably connected to a movable seat 230. The top of the movable seat 230 is provided with a force-bearing column 240. A drive box 250 is provided on one side of the middle of the two limiting plates 220. The outer wall of the force-bearing column 240 is provided with a support ring 260.

[0031] In one specific embodiment, the movable seat 230 facilitates the adjustment of the position of the load-bearing column 240 by the user through the internal structure of the drive box 250. The screw nut 900, through the engagement of the external thread with the limiting plate 220, moves the movable seat 230. The movement of the movable seat 230 moves the load-bearing column 240 at its top, bringing it closer to the bending head 1700. This allows for adjustment of the distance between the load-bearing column and the bending head 1700 to accommodate steel bars of different sizes, thereby achieving the adjustment purpose.

[0032] Please see Figure 1-3 The protective component 300 includes a protective cover 310 hinged to the top of the support box 100. Both ends of the protective cover 310 are provided with material conveying grooves. A plug 320 is provided at one corner of the protective cover 310. An auxiliary seat 330 is inserted and connected to the bottom of the plug 320. A pressure sensor is provided on the inner wall of the auxiliary seat 330.

[0033] In one specific embodiment, the protective cover 310 facilitates bending of the reinforcing bars through the feed chute using the bending head 1700 and the force-bearing column 240. When the user's arm extends into the protective cover 310 through the feed chute, the safety laser scanner 350 scans the user's arm and sends the information to the controller, triggering an emergency stop. When the protective cover 310 is on the support box 100, the plug 320 inserts into the auxiliary seat 330 and applies pressure to the pressure sensor. When the protective cover 310 is opened, the plug 320 slides out of the auxiliary seat 330, and the infrared sensor 360 simultaneously detects that the protective cover 310 has been opened. Both the pressure sensor and the infrared sensor 360 send information to the controller, preventing it from starting the equipment until the protective cover 310 is closed, thus achieving the purpose of protection.

[0034] Please see Figure 5 A torque motor 400 is installed at the bottom of the inner wall of the drive box 250. A worm 500 is installed at the end of the output shaft of the torque motor 400. A worm wheel 600 is meshed at the top of the worm 500. A rotating rod 700 is installed inside the worm wheel 600.

[0035] In one specific embodiment, the torque motor 400 is provided so that the controller can turn on the torque motor 400 during use, so that the torque motor 400 drives the worm 500 to rotate, the worm 500 drives the worm wheel 600, the worm wheel 600 drives the rotating rod 700 to rotate, the rotating rod 700 drives the lead screw nut 900 to rotate, and the lead screw nut 900 drives the moving seat 230 to move.

[0036] Please see Figure 5 A limit plate 800 is provided on one side of the rotating rod 700, which penetrates the inner wall of the drive box 250. A lead screw nut 900 is provided on one side of the limit plate 800, and the outer wall of the lead screw nut 900 is threadedly connected to the moving seat 230.

[0037] In one specific embodiment, the limiting plate 800 facilitates the limiting of the movable seat 230, preventing the movable seat 230 from falling off the lead screw nut 900 onto the rotating rod 700 and getting stuck, thus improving the stability during use.

[0038] Please see Figure 5 A fixed head 1000 is rotatably connected to one side of the lead screw nut 900. One side of the fixed head 1000 is fixedly connected to the inner wall of the connecting plate 210. One end of the auxiliary seat 330 is fixedly connected to the support box 100. One end of the worm gear 500 is rotatably connected to one end of the inner wall of the drive box 250. The other side of the rotating rod 700 is rotatably connected to one side of the inner wall of the drive box 250.

[0039] In one specific embodiment, the provided support box 100 facilitates the support and fixation of its internal parts during use, making the internal parts more stable during use and preventing damage during use.

[0040] Please see Figure 2 A rotating cylinder 1100 is rotatably connected to the outer wall of the support column 110. The outer wall of the rotating cylinder 1100 is rotatably connected to the circular groove. A gear ring 1200 is provided on the outer wall of the rotating cylinder 1100. A gear 1300 is meshed on one side of the gear ring 1200. A connecting rod 1400 is provided inside the gear 1300. An electromagnetic brake motor 1500 is provided at the bottom corner of the inner wall of the support box 100. The output shaft end of the electromagnetic brake motor 1500 is fixedly connected to the connecting rod 1400. The top of the connecting rod 1400 is rotatably connected to the top of the inner wall of the support box 100.

[0041] In one specific embodiment, the electromagnetic brake motor 1500 facilitates the user to place the steel bar through the feed chute between the bending head 1700 and the force-bearing column 240. At this time, the controller activates the electromagnetic brake motor 1500, which drives the connecting rod 1400 to rotate the gear 1300. The rotation of the gear 1300 drives the gear ring 1200 to rotate, which in turn drives the rotating drum 1100 to rotate the drive ring 1600. The drive ring 1600 then moves the bending head 1700 and cooperates with the force-bearing column 240 to bend the steel bar.

[0042] Please see Figure 2The top of the rotating drum 1100 is provided with a drive ring 1600, the top of the drive ring 1600 is provided with a bending head 1700, the inside of the drive ring 1600 is rotatably connected to the connecting plate 210, the bottom of the drive ring 1600 is rotatably connected to the support box 100, and a controller is provided at one side corner of the support box 100.

[0043] In one specific embodiment, the provided drive ring 1600 facilitates the rotation of the bending head 1700 during use, thereby bending the steel bars and improving work efficiency.

[0044] Please see Figure 1-5 The pressure sensor, safety laser scanner 350, infrared sensor 360, torque motor 400 and electromagnetic brake motor 1500 are all electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0045] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0046] In use, the movable seat 230 facilitates adjustment of the position of the load-bearing column 240 by the user when necessary. The user drives the lead screw nut 900 through the internal structure of the drive box 250. The lead screw nut 900, through its external thread engagement with the limiting plate 220, moves the movable seat 230. This movement of the movable seat 230 then moves the load-bearing column 240 at its top, bringing it closer to the bending head 1700. This allows for adjustment of the distance between the column and the bending head 1700 to accommodate different sizes of reinforcing bars, thus achieving the adjustment purpose. Finally, the protective cover 310 facilitates the user's operation by allowing the reinforcing bar to pass through the conveying trough and utilize the bending head 1700. When the 00 and the force column 240 are bent, and the user's arm is inserted into the protective cover 310 through the feed chute, the safety laser scanner 350 will scan the user's arm and feed the information back to the controller, causing an emergency stop. When the protective cover 310 is on the support box 100, the plug 320 will be inserted into the auxiliary seat 330 and apply pressure to the pressure sensor. When the protective cover 310 is opened, the plug 320 will slide out from the auxiliary seat 330, and the infrared sensor 360 will simultaneously detect that the protective cover 310 has been opened. Finally, the pressure sensor and the infrared sensor 360 will feed the information back to the controller, preventing it from starting the equipment. The machine can only be driven after the protective cover 310 is closed, thus achieving the purpose of protection.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
