Description

Technical Field

[0001] The utility model relates to the field of steel bar bending tools, in particular to a small-diameter steel bar bending device. Background Art

[0002] The commonly used manual bending machine JB / T12077-2014 is mainly used to bend or hook small steel bars, and is widely used in the field of construction. It can bend Φ4-Φ12 mm round steel into various geometric shapes required by the project. It can better process into the specified angle and model. It is suitable for bending hooks and hoops of cold-rolled ribbed steel bars, hot-rolled grade 3 steel bars, cold-rolled plain round steel bars and hot-rolled coil round steel bars.

[0003] However, since this manual bending machine is large in size and is made of solid steel casting or forging, long-term use can easily cause fatigue and soreness in the hands. In addition, this bending machine is large in size, and it is inconvenient to bend small steel bars close together, so the bending efficiency is low. Summary of the invention

[0004] In view of the problems existing in the background technology, the utility model proposes a small-diameter steel bar bending device, which has a light structure and reduces fatigue of both hands in small processes where the hands are relatively close together.

[0005] To achieve the above object, the utility model adopts the following technical solution: a small diameter steel bar bending device, comprising a blade and a handle arranged at one end of the blade, the blade having a clamping portion and a hooking portion, the clamping portion and the hooking portion being arranged at the other end of the blade in sequence, and the center point of the object hung by the hooking portion is located on the axis of the handle, the clamping portion is arranged at a distance on one side of the axis of the handle, and the blade is constructed as a V-shaped bending structure;

[0006] A V-shaped opening is provided on the blade body from the engaging portion to the hooking portion, and the hooking portion includes a symmetrical first hanging wall and a second hanging wall, the first hanging wall and the second hanging wall are rotatably connected to the ends of the opening, and the first hanging arm and the second hanging arm are provided with long holes, and a connecting block is hinged on the blade body between the engaging portion and the handle, a screw rod is passed between the connecting block and the long hole, and a nut for limiting the rotation of the first hanging arm and the second hanging arm is threadedly connected to the screw rod.

[0007] Furthermore, the length of the clamping portion from the handle along the axis of the handle to the handle is greater than the length of the clamping portion from the handle along the axis of the handle to the hooking portion;

[0008] Furthermore, a flexible material layer is provided on the outer side of the handle.

[0009] Beneficial effects of the utility model: During use, the utility model can manually bend small steel bars by hanging the hook part on a tubular auxiliary object, so that the small steel bars contact the tubular object and the bottom of the V-shaped opening of the clamping part at the same time. If it is necessary to bend the small steel bars, the hook part is hung on the thick steel bars perpendicular to the small steel bars. Since the clamping part presses against the small steel bars to bend after the device is directly hung, the operation process is relatively simple, and the blade structure is simple, so the bending efficiency of small steel bars can be improved during use, and the labor intensity of steel bar workers can also be reduced.

[0014] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0015] See also Figures 1 to 4 The invention discloses a small-diameter steel bar bending device 1, which mainly comprises a blade body 102 and a handle 101 for holding arranged at one end of the blade body 102. A flexible material layer 1011 is also arranged on the outside of the handle 101 to improve the comfort of holding the handle 101 and prevent the handle 101 from causing damage or wear to the worker's palm.

[0016] like Figure 3 The blade 102 of the bending device 1 shown has a clamping portion 1021 and a hooking portion 1023. The clamping portion 1021 mainly supports small steel bars, while the hooking portion 1023 is mainly used to hook auxiliary pipes or thick steel bars to facilitate the bending or hooking of small steel bars 2. The clamping portion 1021 and the hooking portion 1023 are sequentially arranged at the other end of the blade 102 of the bending device 1, and the center point 1026 of the object hung by the hooking portion 1023 is located on the handle axis 1012. The clamping portion 1021 is arranged on one side of the handle axis 1012 at a distance, and the blade is constructed into a V-shaped bending structure. The hung object is a columnar structure such as a pipe or a thick steel bar, which is used to assist the bending device 1 in the bending operation. The thick steel bar is the steel bar that the small steel bar is to be bent and hooked, or the annular rib of the building support column such as Figure 4 shown.

[0017] like Figure 1 , Figure 2 The blade 102 from the engaging portion 1021 to the hooking portion 1023 is provided with a V-shaped opening 1022, and the hooking portion 1023 includes a first hanging wall 1024 and a second hanging wall 1025 that are symmetrical. Figure 4 As shown, when performing the bending operation, the small steel bar will contact the tubular object and the bottom (tip) of the V-shaped opening 1022 of the clamping part 1021 at the same time, so that the bottom of the V-shaped opening 1022 clamps the small steel bar. The first hanging arm 1024 and the second hanging arm 1025 hook the thick steel bar 3 or the annular steel bar at the same time. The thick steel bar 3 or the annular steel bar is used as an auxiliary object for the bending operation. The handle 101 is held to rotate the blade 102 along the center point 1026 (the axis of the tubular member) of the hung object toward the side of the clamping part 1021, so that the small steel bar can be manually bent.

[0018] If the small steel bar is bent and hooked, the hook portion 1023 is also hung on the thick steel bar perpendicular to the small steel bar. Figure 4 As shown, during the bending process, the small steel bar will bend along the thick steel bar and hook the thick steel bar, realizing the bending and hooking process of the small steel bar end during the steel bar bundling construction process. Since the device is directly hung, the clamping part 1021 presses against the small steel bar to bend, the whole operation process is relatively simple, and the blade 102 has a simple structure, so the bending efficiency of the small steel bar can be improved during use, and the labor intensity of the steel bar worker can also be reduced. In addition, the opening 1022 is a V-shaped structure, which can adapt to the clamping of small steel bars of different sizes and specifications, expanding the scope of application of the bending device 1.

[0019] like Figures 1 to 4 In some preferred embodiments shown in the figure, the first hanging wall 1024 and the second hanging wall 1025 are rotatably connected (hinged) to the ends of the opening 1022, and the first hanging arm 1024 and the second hanging arm 1025 are provided with a long hole 1027. A connecting block 104 is hingedly connected to the blade body 102 between the engaging portion 1021 and the handle 101, and a screw 103 is passed between the connecting block 104 and the long hole 1027. A hole corresponding to the screw is provided on the connecting block 104, and the hole of the connecting block 104 is threadedly connected to the screw 103. The long hole 1027 and the screw 103 are clearance-matched, and the screw 103 can slide back and forth freely along the length direction of the long hole 1027. A nut 105 for limiting the rotation of the first hanging arm 1024 and the second hanging arm 1025 is threadedly connected to the screw 103, and the nut 105 is set at Figure 3The screw rod 103 position in the middle can be adjusted by rotating the nut 105 to adjust the rotation angle of the first hanging arm 1024 and the second hanging arm 1025. Thus, during use, the relative position of the engaging portion 1021 and the hooking portion 1023 can be adjusted to adapt to the force size and force angle of different workers.

[0020] like Figure 3 The length of the engaging portion 1021 of the bending device 1 shown along the direction of the handle axis 1012 to the handle 101 is greater than the length of the engaging portion 1021 along the direction of the handle axis 1012 to the hooking portion 1023, so that the distance from the engaging portion 1021 to the handle 101 is constructed as a long arm of a rotating lever, while the distance from the engaging portion 1021 to the hooking portion 1023 is a short arm, which reduces the bending force and further reduces the labor intensity of the workers.

[0021] It should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
