Abstract
Description
Technical Field
[0001] This application relates to the technical field of steel bar bending, and in particular to a steel bar bending machine. Background Technology
[0002] A bending machine is a machine that can bend steel bars. Its structure mainly includes a support, a worktable and a clamping plate. The worktable is placed on the support and consists of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base consists of a housing, a coil and a cover plate. The coil is placed in the recess of the housing and the top of the recess is covered by a cover plate.
[0003] However, in practical applications, most existing bending machines typically involve placing the reinforcing bar flat on the machine and maintaining its front and rear position limits. However, during bending and use, the end of the reinforcing bar is prone to warping under stress, which can lead to varying degrees of bending deformation of the entire bent reinforcing bar, affecting its subsequent use and hindering its widespread adoption.
[0004] Therefore, those skilled in the art have provided a rebar bending machine to solve the problems mentioned in the background art. Utility Model Content
[0005] To address the issue raised in the background art that, during bending and use, the tail end of the reinforcing bar is prone to warping under stress, leading to varying degrees of bending deformation of the bent reinforcing bar, which affects its subsequent use and hinders its widespread adoption, this application provides a reinforcing bar bending machine.
[0006] The steel bar bending machine provided in this application adopts the following technical solution: it includes two side plates, and a motor is fixedly connected to the rear side of the rear side plate. The output shaft of the motor is fixedly connected to a U-shaped bending roller. The U-shaped bending roller is rotatably connected to the outer side of the two side plates. Multiple first clamping rollers are rotatably connected to the opposite side of the two side plates. Rectangular holes are opened on the outer side of the two side plates. The same I-frame is slidably connected to the inner wall of the two rectangular holes. Multiple identical second clamping rollers are rotatably connected to the inner walls of the front and rear sides of the I-frame. The multiple first clamping rollers correspond one-to-one with the multiple second clamping rollers.
[0007] Preferably, the plurality of first clamping wheels and the plurality of second clamping wheels are all designed in a gourd-shaped V-shape.
[0008] Preferably, the top sides of the two side plates are fixedly connected to the same mounting plate, the top side of the mounting plate is fixedly connected to an electric push rod, and the output shaft of the electric push rod is fixedly connected to the top side of the I-beam frame.
[0009] Preferably, two guide rods are fixedly connected to the bottom inner walls of the two rectangular holes, and the I-beam is slidably sleeved with the four guide rods.
[0010] In summary, this application includes the following beneficial technical effects:
[0011] 1. By setting up first and second clamping rollers, the reinforcing bar is inserted from the right side to the left of the equipment. When passing between the two side plates, multiple first clamping rollers and multiple second clamping rollers can clamp and fix the passing reinforcing bar. After the reinforcing bar moves to the designated position, the output shaft of the motor drives the U-shaped bending roller to rotate. The force generated by the bending and flipping of the U-shaped bending roller can be offset by the first and second clamping rollers. Using this method, it can be effectively ensured that the reinforcing bar will not deform after bending, avoiding affecting the normal use afterwards, which is conducive to its widespread use.
[0012] 2. The first clamping rollers and the second clamping rollers are all designed in a gourd-shaped V-shape. When the first clamping rollers and the second clamping rollers clamp and fix the steel bars, the first clamping rollers and the second clamping rollers are embedded together with the steel bars. The clamping rollers of this shape can prevent the steel bars from shifting their position back and forth when bending. Attached Figure Description

[0017] The following will be combined with the appendix Figure 1-3 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] This application discloses a steel bar bending machine, referring to... Figure 1-3The system includes two side plates 1. A motor 2 is fixedly connected to the rear side plate 1. The output shaft of the motor 2 is fixedly connected to a U-shaped bending roller 3. The U-shaped bending roller 3 is rotatably connected to the outer sides of the two side plates 1. Multiple first clamping rollers 4 are rotatably connected to opposite sides of the two side plates 1. Rectangular holes are provided on the outer sides of both side plates 1. The same I-frame 5 is slidably connected to the inner walls of the two rectangular holes. Multiple identical second clamping rollers 6 are rotatably connected to the inner walls of the front and rear sides of the I-frame 5. The multiple first clamping rollers 4 correspond one-to-one with the multiple second clamping rollers 6. Place the first clamping roller 4 and the second clamping roller 6, and insert the steel bar from the right side to the left of the equipment. When the steel bar passes between the two side plates 1, the multiple first clamping rollers 4 and the multiple second clamping rollers 6 can clamp and fix the steel bar. After the steel bar moves to the designated position, the output shaft of the motor 2 drives the U-shaped bending roller 3 to rotate. The force generated by the bending and flipping of the U-shaped bending roller 3 can be offset by the first clamping roller 4 and the second clamping roller 6. Using this method, it can be effectively ensured that the steel bar will not deform after bending, so as to avoid affecting the normal use in the future and promote its widespread use.
[0019] In this application, the multiple first clamping wheels 4 and the multiple second clamping wheels 6 are all designed in a gourd-shaped V-shape. By setting the multiple first clamping wheels 4 and the multiple second clamping wheels 6 to be designed in a gourd-shaped V-shape, when the first clamping wheels 4 and the second clamping wheels 6 clamp and fix the steel bars, the first clamping wheels 4 and the second clamping wheels 6 are embedded together with the steel bars. The clamping wheels of this shape can prevent the steel bars from shifting their position back and forth when bending.
[0020] In this application, the top sides of the two side plates 1 are fixedly connected to the same mounting plate 7, and the top side of the mounting plate 7 is fixedly connected to an electric push rod 8. The output shaft of the electric push rod 8 is fixedly connected to the top side of the I-frame 5. By setting the electric push rod 8, when the output shaft of the electric push rod 8 drives the I-frame 5 to move up or down, the distance between the first clamping wheel 4 and the second clamping wheel 6 can be adjusted, thereby satisfying the bending operation of steel bars of different diameters. This improves the applicability.
[0021] In this application, two guide rods 9 are fixedly connected to the bottom inner walls of the two rectangular holes, and the I-frame 5 is slidably sleeved with the four guide rods 9; by setting the guide rods 9, when the I-frame 5 moves up or down, the four guide rods 9 cooperate with each other to keep the I-frame 5 moving in the vertical direction and avoid breakage.
[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0023] The implementation principle of the rebar bending machine in this application embodiment is as follows: During use, the rebar is inserted from the right side to the left of the equipment. As it passes between the two side plates 1, multiple first clamping rollers 4, in conjunction with multiple second clamping rollers 6, clamp and fix the passing rebar. After the rebar moves to a designated position, the output shaft of the motor 2 drives the U-shaped bending roller 3 to rotate. The bending and tumbling force generated by the U-shaped bending roller 3 can be counteracted by the first clamping rollers 4 and the second clamping rollers 6. This method effectively ensures that the rebar does not deform after bending, avoiding impact on subsequent bending processes. This design is commonly used and facilitates widespread adoption. Multiple first clamping rollers 4 and multiple second clamping rollers 6 are designed in a gourd-like V-shape. When the first clamping rollers 4 and second clamping rollers 6 clamp and fix the reinforcing bar, they are embedded together with the reinforcing bar. This shape of the clamping rollers prevents the reinforcing bar from shifting its position during bending. When the output shaft of the electric push rod 8 moves the I-frame 5 up or down, the distance between the first clamping rollers 4 and second clamping rollers 6 can be adjusted, thus meeting the bending requirements for reinforcing bars of different diameters. This improves the applicability. When the I-frame 5 moves up or down, the four guide rods 9 cooperate to keep the I-frame 5 moving vertically, preventing it from splitting.
[0024] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
