Description

Technical Field

[0001] This utility model belongs to the field of steel bar processing technology for irregularly shaped liquid storage tanks, specifically, it relates to a device for bending the steel bars of the tank wall of an irregularly shaped liquid storage tank. Background Technology

[0002] Pool walls are often designed in a ring, arc, or variable cross-section, requiring precise control of the bending curvature and spatial positioning of the reinforcing bars. Traditional manual operation is prone to cumulative errors, while using reinforcing bar bending equipment to bend the bars in advance, and then fine-tuning the curvature of the reinforcing bars during installation, is necessary to achieve the optimal spacing between them.

[0003] The prior art discloses a rebar bending device (CN222740137U), including a worktable. Inside the worktable is a bending device body for bending rebars. Pressing mechanisms for clamping the rebars are located on the left and right sides of the worktable. A control panel for operating the device is fixed to the back wall of the worktable cavity. A shielding mechanism for protecting the control panel is located on the right side of the worktable cavity. Under the action of the pressing mechanism, the rebar is clamped and fixed by a cylinder, a fixed box, a lifting plate, and a support plate. With the assistance of an upper limit rod, a pressing plate, a tension spring, and a limiting plate, the rebar is clamped while allowing it to move smoothly forward or backward during bending, thus enabling the rebar to complete the bending process smoothly. Simultaneously, a pressure sensor is used to prevent excessive clamping force from preventing the clamped portion of the rebar from moving forward or backward, which would cause the bending process to fail.

[0004] The search revealed that existing devices use fixed limiting plates, which can only achieve bending at a single angle. They cannot adapt to complex curvature changes such as arcs and polygons required for irregularly shaped liquid storage tanks. The lack of a dynamic adjustment mechanism leads to frequent mold changes for bending at different radii, resulting in low efficiency. At the same time, the lack of a dynamic adaptation mechanism during the bending of steel bars can lead to excessive bending of the steel bars due to excessive hardness, affecting subsequent use.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0010] An auxiliary structure is movably mounted on the workbench and support frame.

The handle threaded rod is threaded onto the support frame. The movable clamping block is slidably mounted on the top surface of the workbench. The fixed clamping block is fixedly mounted on the top surface of the workbench. The telescopic rod is movably mounted between the mounting frame and the rack. The clamping plate is movably mounted within the mounting frame.

[0011] In a preferred embodiment of this utility model, the workbench has a circular groove inside, a cylinder is fixedly installed inside the circular groove, the output end of the cylinder is connected to a push rod, the turntable is rotatably mounted on the top surface of the push rod, the turntable is slidably mounted in the circular groove, and the control panel is electrically connected to the cylinder.

[0012] In a preferred embodiment of this utility model, the turntable has a T-shaped moving groove inside, a hydraulic rod is fixedly installed in the moving groove, a moving block is slidably arranged in the moving groove, the output end of the hydraulic rod is connected to one side of the moving block, the bending clamp is fixedly arranged on the top surface of the moving block, and the control panel is electrically connected to the hydraulic rod.

[0013] In a preferred embodiment of this utility model, the bottom corner of the support frame is threadedly connected to the handle thread rod. The movable clamping block and the fixed clamping block are the same in shape and size, both being trapezoidal blocks. The movable clamping block and the fixed clamping block are symmetrically arranged on the top surface of the workbench. The movable clamping block and the fixed clamping block are arranged corresponding to the fixed block and the bending clamping block. The fixed block and the bending clamping block are both frustum structures. The handle thread rod is rotatably connected to the movable clamping block.

[0014] In a preferred embodiment of this utility model, a motor is fixedly mounted on the top surface of the support frame, the output end of the motor passes through the support frame and is connected to the top surface of the gear, a telescopic coupling is installed between the fixed block and the gear, the fixed block and the gear are linked through the telescopic coupling, and the control panel is electrically connected to the motor.

[0015] In a preferred embodiment of this utility model, a sliding groove is provided on the inner wall of the support frame, and a slider is fixedly provided on the top surface of the rack. The slider slides in the sliding groove, and the gear meshes with the rack.

[0016] In a preferred embodiment of this utility model, a universal joint is installed at the end of the rack away from the fixed clamping block. The rack is connected to the telescopic rod through the universal joint. The telescopic rod is located between the mounting frame and the universal joint.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. By setting up an auxiliary structure in conjunction with the bending component, the trapezoidal shape of the movable and fixed clamping blocks adapts to the size and specifications of the reinforcing bars. Simultaneously, the bending component limits the position of the reinforcing bars, preventing them from shifting on the inclined surface of the fixed block during bending. The fixed block and bending clamping block, with their frustum structure, compress the reinforcing bars. A turntable moves up and down within the worktable, allowing the reinforcing bars to conform to fixed blocks of different heights. This utilizes the special inclined surface of the frustum structure to achieve bending angles of varying curvatures without the need to change molds, enabling dynamic adjustment of multiple curvatures and thus improving efficiency.

[0019] 2. By setting up an auxiliary structure, the front end of the reinforcing bar is fixed using a clamp. The gear drives the turntable to bend the reinforcing bar while simultaneously driving the rack to move the clamp. This, in turn, uses the clamp to pull the reinforcing bar, thus assisting in bending and protecting it. This prevents excessive bending and damage caused by excessive hardness, ensuring its continued use.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] A device for bending the steel bars of an irregularly shaped liquid storage tank, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0030] The workbench 10 has a support frame 12 fixedly installed on its top surface, and a control panel 11 is installed on one side of the workbench 10.

[0031] A bending assembly is movably disposed between the worktable 10 and the support frame 12. The bending assembly includes a turntable 21, a fixing block 22, a bending clamping block 24, a gear 27, and a rack 32. The turntable 21 is movably disposed inside the worktable 10. The fixing block 22 is fixedly disposed at the center of the top surface of the turntable 21. The bending clamping block 24 is slidably disposed on the turntable 21. The gear 27 is rotatably disposed on the inner wall surface of the support frame 12. The rack 32 is slidably disposed on the inner wall surface of the support frame 12.

[0032] The auxiliary structure is movably mounted on the workbench 10 and the support frame 12. The auxiliary structure includes a handle threaded rod 14, a mounting frame 15, a movable clamping block 16, a fixed clamping block 17, a telescopic rod 30, and a clamping plate 34. The handle threaded rod 14 is threaded onto the support frame 12. The movable clamping block 16 is slidably mounted on the top surface of the workbench 10. The fixed clamping block 17 is fixedly mounted on the top surface of the workbench 10. The telescopic rod 30 is movably mounted between the mounting frame 15 and the rack 32. The clamping plate 34 is movably mounted inside the mounting frame 15.

[0033] Specifically, the reinforcing bar enters the device and is fixed at the rear end through the fixed clamping block 17 and the movable clamping block 16. The front end of the reinforcing bar is clamped and fixed by two clamping plates 34. The fixed block 22 and the bending clamping block 24 are adapted to the size of the reinforcing bar. The rotating turntable 21 drives the fixed block 22 and the bending clamping block 24 to rotate and bend the reinforcing bar. At this time, the gear 27 drives the rack 32 to move. The rack 32 pulls the mounting frame 15 through the telescopic rod. The mounting frame 15 drives the reinforcing bar in the clamping plate 34 to assist in tightening during the bending process.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a circular groove is provided inside the workbench 10, and a cylinder 19 is fixedly installed inside the circular groove. The output end of the cylinder 19 is connected to a push rod 20. A turntable 21 is rotatably mounted on the top surface of the push rod 20 and is slidably mounted in the circular groove. The control panel 11 is electrically connected to the cylinder 19.

[0035] like Figure 1 and Figure 3 As shown, the turntable 21 has a T-shaped moving groove 23 inside, a hydraulic rod 26 is fixedly installed in the moving groove 23, a moving block 25 is slidably arranged in the moving groove 23, the output end of the hydraulic rod 26 is connected to one side of the moving block 25, the bending clamp 24 is fixedly arranged on the top surface of the moving block 25, and the control panel 11 is electrically connected to the hydraulic rod 26.

[0036] Specifically, the control panel 11 drives the cylinder 19 to start, the cylinder 19 pushes the push rod 20 to rise and fall, the push rod 29 pushes the turntable 21 to rise and fall in the circular groove, the exposed parts of the fixed block 22 and the bending clamping block 24 in the circular groove are used to compress and bend the steel bars, and the curvature of the exposed parts of the two corresponds to the curvature of the steel bar bend. Without changing the mold, dynamic adjustment of multiple curvatures is realized, thereby improving efficiency. The control panel 11 drives the hydraulic rod 26 to start, the hydraulic rod 26 drives the moving block 25 to slide in the moving groove 23, the sliding moving block 25 drives the bending clamping block 24 to move closer to or away from the fixed block 22, thereby clamping the steel bars according to their specifications and sizes.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, the bottom corner of the support frame 12 is threadedly connected to the handle thread rod 14. The movable clamping block 16 and the fixed clamping block 17 are the same in shape and size, both being trapezoidal blocks. The movable clamping block 16 and the fixed clamping block 17 are symmetrically arranged on the top surface of the workbench 10. The movable clamping block 16 and the fixed clamping block 17 are set corresponding to the fixed block 22 and the bending clamping block 24. The fixed block 22 and the bending clamping block 24 are both frustum structures. The handle thread rod 14 is rotatably connected to the movable clamping block 16.

[0038] Specifically, the support frame 12 consists of a square plate and four support legs. One corner support leg has a threaded hole. The handle threaded rod 14 is threaded to the support frame 12 through the threaded hole. The fixed block 22 and the bending clamp 24 are the same in shape and size but have different orientations. The fixed block 22 is oriented with a narrow top and a wide bottom, while the bending clamp 24 is oriented in the opposite direction. The two form a spaced area with a cross-section resembling a parallelogram. In use, rotating the handle threaded rod 14 pushes the movable clamp 16 closer to or away from the fixed clamp 17. A trapezoidal space is formed between the movable clamp 16 and the fixed clamp 17. The reinforcing bar is clamped in the trapezoidal space. When the reinforcing bar is bent, the trapezoidal space limits the position of the reinforcing bar to prevent the reinforcing bar from sliding or deviating in the area between the fixed block 22 and the bending clamp 24.

[0039] like Figure 3 and Figure 4 As shown, a motor 13 is fixedly installed on the top surface of the support frame 12. The output end of the motor 13 passes through the support frame 12 and is connected to the top surface of the gear 27. A telescopic coupling 28 is installed between the fixed block 22 and the gear 27. The fixed block 22 and the gear 27 are linked through the telescopic coupling 28. The control panel 11 is electrically connected to the motor 13.

[0040] like Figure 2 and Figure 4 As shown, a groove 18 is provided on the inner wall of the support frame 12, and a slider 31 is fixedly provided on the top surface of the rack 32. The slider 31 slides in the groove 18, and the gear 27 meshes with the rack 32.

[0041] like Figure 4 and Figure 5 As shown, a universal joint 29 is installed at the end of the rack 32 away from the fixed clamping block 17. The rack 32 is connected to the telescopic rod 30 through the universal joint 29. The telescopic rod 30 is located between the mounting frame 15 and the universal joint 29. Two spring buffers 33 and a clamping plate 34 are symmetrically installed inside the mounting frame 15. The spring buffers 33 are fixedly installed between the mounting frame 15 and the clamping plate 34.

[0042] Specifically, the control panel 11 controls the start and speed of the motor 13. Depending on the required bending curvature, the control panel 11 controls the cylinder 19 to push the push rod 20 and turntable 21 to a suitable height. Simultaneously, with the cooperation of the universal joint 29 and the telescopic rod 30, the universally rotating mounting frame 15 drives the two internal clamping plates 34 to clamp the front end of the rebar. At this time, the tail end of the rebar is fixedly clamped by the movable clamping block 16 and the fixed clamping block 17, and is adaptively clamped by the fixed block 22 and the bending clamping block 24 exposed on the top surface of the workbench 10. The front end is elastically clamped by the two clamping plates 34 inside the universally rotating and telescopic mounting frame 15. The motor 13 controls the gear 27 to rotate according to the required bending shape and curvature. Simultaneously, the rotation of the gear 27 drives the fixed block 22 and the turntable 21 to rotate via the telescopic coupling 28. The disc 21 drives the bending clamp 24 to bend the steel bar. At the same time, the rotating gear 27 meshes with the transmission rack 32. The rack 32 moves towards the movable clamp 16 and the fixed clamp 17. At this time, the rack 32 pulls the mounting frame 15 through the universal joint 29 and the telescopic rod 30. The mounting frame 15 pulls the front end of the steel bar through the two internal clamps 34. At this time, the steel bar is bent. It should be noted that due to the universal characteristic of the universal joint 29, there may be a situation where the rack 32 pulls the mounting frame 15, but the mounting frame 15 does not move. To avoid this situation, the universal joint 29 needs to be a damping universal joint with strong braking force, or the movement direction of the universal joint 29 can be manually limited before the pulling process. A U-shaped plate can be used to limit the movement direction of the universal joint 29. The limiting method can be adopted according to the actual needs.

[0043] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
