Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel bar bending technology, and in particular relates to a steel bar bending device. Background Technology
[0002] Steel bars are a consumable material used in large quantities during building construction, such as in the binding and processing of steel cage structures. During construction, it is often necessary to bend the ends of the steel bars to form hooks, which facilitates their use as a suspension structure to be hung on the main structure of the steel cage.
[0003] During construction, the current construction method for bending a large number of steel bars of the same size is to use large bending machines. Large equipment is mainly used for bending precast steel bar structures with large diameters and large quantities.
[0004] In actual construction sites, it is often necessary to temporarily fabricate various steel reinforcement structures with bends to fit the main steel cage structure. Obviously, large bending equipment cannot be used for processing, so a highly flexible and labor-saving steel reinforcement bending device is needed to process the steel reinforcement as needed on the construction site.
[0005] However, there is currently no simple, convenient, and easy-to-operate rebar bending equipment that facilitates the rapid fabrication of rebar structures on-site. The current method involves operators using tools such as wrenches or steel pipes to pry and bend the rebar, but this method has the drawback of being difficult to operate, especially on a construction site, making it challenging to bend the rebar flexibly and easily. Utility Model Content
[0006] Based on the above background, the purpose of this utility model is to provide a steel bar bending device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A steel bar bending device includes a steel bar guide bin, and the steel bar guide bin has a guide cavity for guiding steel bar materials;
[0009] The lower end of the steel bar guide hopper is equipped with a steel bar pushing mechanism, and the upper end of the steel bar guide hopper is equipped with a steel bar bending mechanism.
[0010] The steel bar bending mechanism includes a pair of bar support rollers installed on both sides of the steel bar guide bin. During the bending process of the steel bar, the bar support rollers serve as fulcrums.
[0011] The steel bar bending mechanism also includes a flipping bracket hinged to the upper end of the steel bar guide hopper. An adjusting sleeve for attaching the steel bar is installed on the flipping bracket. During the bending process, the steel bar extends into the adjusting sleeve, and the adjusting sleeve flips until the steel bar is bent.
[0012] Preferably, the shape of the steel bar guide hopper is cuboid;
[0013] The guide cavity is cylindrical in shape.
[0014] Preferably, the bar stock support roller is equipped with a support roller bracket, and the support roller bracket is installed at the upper end of the steel bar guide hopper through a spacing adjustment structure.
[0015] Preferably, the spacing adjustment structure includes a plurality of sliding screws fixedly connected to the steel bar guide hopper, and the sliding screws are slidably connected to the support wheel bracket;
[0016] The sliding screw is threaded with a pair of adjusting nuts positioned on both sides of the support wheel bracket.
[0017] Preferably, the tilting bracket is U-shaped, and the lower end of the tilting bracket is hinged to the upper end of the steel bar guide hopper by a pin.
[0018] The adjusting sleeve is threaded onto the flip-up bracket.
[0019] Preferably, a drive handle is fixedly connected to the top of the adjusting sleeve, and a tapered guide section is integrally formed at the bottom of the adjusting sleeve.
[0020] Preferably, the steel bar pushing mechanism includes pusher structures respectively installed on both sides of the lower end of the steel bar guide bin;
[0021] The pusher structure includes a pusher wheel, and a bracket that is rotatably connected to the side wall of the steel bar guide hopper. A motor that drives the pusher wheel to rotate is installed on the bracket. The steel bar material passes through the pusher wheel and is gradually fed into the steel bar guide hopper under the squeezing and pushing of the pusher wheel.
[0022] Preferably, the push wheel is made of elastic rubber, and an annular groove structure for limiting steel bars is formed on the outline of the push wheel.
[0023] Preferably, the bottom of the bracket is fixedly connected to a support bracket, and the bottom of the support bracket is fixedly connected to a support base.
[0024] This utility model has the following beneficial effects:
[0025] 1. During the operation, a steel bar of a certain length is inserted from the top of the steel bar guide hopper. At this time, the steel bar slides out from the bottom part of the steel bar guide hopper. The steel bar pushing mechanism pushes the steel bar upward to the top of the steel bar guide hopper, and then the steel bar bending mechanism performs the bending operation.
[0026] After bending, decide whether to continue bending. If necessary, continue pushing the steel bar out and then bend it. If not, pull out the steel bar to complete the processing.
[0027] 2. During the operation, when the upper end of the bar extends into the adjusting sleeve through the conical guide (conical cap), the operator turns the drive handle. Driven by the drive handle, the adjusting sleeve is rotated. During the rotation, the end of the bar gradually bends to fit against the bar support wheel. Using the bar support wheel as a fulcrum, it continues to bend, forming a hook shape as required.
[0028] This method enables labor-saving processing of steel bar bending. Because the spacing of the bar support rollers is adjustable, it can process steel bars of different diameters and with different bending angles. For example, if the spacing between the bar support rollers and the steel bar guide bin is increased, the spacing between the adjusting sleeve and the bar support rollers (which serve as fulcrums) will also increase, resulting in a larger bending angle of the steel bar after bending.
[0029] 3. Enable automatic feeding of steel bar materials.
[0030] 4. The structure disclosed in this invention is easy to carry and allows for labor-saving and flexible bending of steel bars. It can be operated on the construction site, greatly improving the convenience and efficiency of on-site fabrication of steel bar bending structures during construction. Attached Figure Description

[0041] Example 1
[0042] like Figure 1-5 As shown, a rebar bending device includes a rebar guide bin 1, which is rectangular in shape. The rebar guide bin 1 also has a guide cavity 11 for guiding the rebar bars, specifically, the guide cavity 11 is cylindrical in shape.
[0043] The lower end of the aforementioned steel bar guide hopper 1 is equipped with a steel bar pushing mechanism, and the upper end of the steel bar guide hopper 1 is equipped with a steel bar bending mechanism.
[0044] During operation, a steel bar of a certain length is inserted from the top of the steel bar guide bin 1. At this time, the steel bar slides out from the bottom part of the steel bar guide bin 1. The steel bar pushing mechanism pushes the steel bar upward to the top protruding from the steel bar guide bin 1. Then the steel bar bending mechanism performs the bending operation.
[0045] After bending, decide whether to continue bending. If necessary, continue pushing the steel bar out and then bend it. If not, pull out the steel bar to complete the processing.
[0046] Specifically, the steel bar bending mechanism includes a pair of bar support rollers 21 (metal material) installed on both sides of the steel bar guide bin 1. During the bending process of the steel bar, the bar support rollers 21 serve as fulcrums.
[0047] The bar support roller 21 is dumbbell-shaped, so the center of the bar support roller 21 forms a concave structure that is recessed inward. During the bending process, the steel bar is supported and limited within the concave structure, which makes the bending more stable.
[0048] Specifically, the bar stock support roller 21 is equipped with a support roller bracket 22, which is installed at the upper end of the steel bar guide hopper 1 through a spacing adjustment structure.
[0049] Meanwhile, the spacing adjustment structure includes several sliding screws 23 fixedly connected to the steel bar guide hopper 1, and the sliding screws 23 are slidably connected to the support wheel bracket 22; a pair of adjusting nuts 231 positioned on both sides of the support wheel bracket 22 are threadedly connected to the sliding screws 23.
[0050] During the operation, as the bar material protrudes from the steel bar guide hopper 1 during the bending process, the bar material passes through the bar material support rollers 21 on both sides. After the end of the bar material is bent, the bar material gradually sticks to the bar material support rollers 21 and continues to bend to the specified bending degree using the bar material support rollers 21 as the fulcrum.
[0051] Example 2
[0052] like Figure 1-5 As shown, based on the structure of Embodiment 1, the above-mentioned steel bar bending mechanism further includes a flipping bracket 31 (the flipping bracket 31 is U-shaped, and the lower end of the flipping bracket 31 is hinged to the upper end of the steel bar guide hopper 1 by a pin) which is hinged to the upper end of the steel bar guide hopper 1. An adjusting sleeve 32 for sleeved steel bar is installed on the flipping bracket 31 (the adjusting sleeve 32 is threadedly connected to the flipping bracket 31, which facilitates the adjustment of the distance between the adjusting sleeve 32 and the top of the steel bar guide hopper 1). During the bending process, the steel bar extends into the adjusting sleeve 32, and the adjusting sleeve 32 flips until the steel bar is bent.
[0053] The top of the aforementioned adjusting sleeve 32 is fixedly connected to a drive handle 321, and the bottom of the adjusting sleeve 32 is integrally formed with a tapered guide part 311.
[0054] During operation, when the upper end of the bar extends into the adjusting sleeve 32 through the conical guide part 311 (conical cap), the operator turns the drive handle 321. Driven by the drive handle 321, the adjusting sleeve 32 is rotated. During the rotation, the end of the bar gradually bends and fits against the bar support wheel 21. Using the bar support wheel 21 as a fulcrum, it continues to bend, forming a hook shape that is required.
[0055] This method enables the bending of reinforcing bars in a labor-saving manner. Furthermore, because the spacing of the bar support rollers 21 is adjustable, it is possible to process reinforcing bars of different diameters and with different bending angles. For example, when the spacing between the bar support rollers 21 and the reinforcing bar guide hopper 1 is increased, the spacing between the adjusting sleeve 32 and the bar support rollers 21, which serve as fulcrums, also increases. In this case, the bending angle of the reinforcing bar is larger after bending.
[0056] Example 3
[0057] like Figure 1-5 As shown, based on the structure of Embodiment 2, the above-mentioned rebar pushing mechanism includes pusher structures installed on the front and rear sides of the lower end of the rebar guide bin 1. The pusher structures automatically push the rebar bars to a higher position, facilitating bending. If bending is required at multiple points in the rebar, the rebar bars can be automatically raised. Furthermore, because the lower end of the rebar bars is clamped between the pusher structures, the rebar bars are kept in position.
[0058] Specifically, the pusher structure includes a pusher wheel 42, and a bracket 43 that is rotatably connected to the side wall of the steel bar guide bin 1 is fixedly connected to the pusher wheel 42. A motor 41 that drives the pusher wheel 42 to rotate is installed on the bracket 43 (same as in the existing method, the output shaft of the motor 41 is fixed on the pusher wheel 42). The steel bar material passes through the pusher wheel 42, and under the squeezing and pushing of the pusher wheel 42, the steel bar material is gradually fed into the steel bar guide bin 1.
[0059] Meanwhile, to increase the driving friction force, the aforementioned driving wheel 42 is made of elastic rubber, and annular groove structures for limiting the reinforcing bar are formed on the outline of the driving wheel 42. The reinforcing bar is limited within the annular groove structures of the two driving wheels 42. Under frictional driving, the reinforcing bar is assisted in being pushed.
[0060] This method allows for convenient raising of steel bar materials.
[0061] The bottom of the aforementioned bracket 43 is fixedly connected to a support bracket 431, and the bottom of the support bracket 431 is fixedly connected to a support base 432.
[0062] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
