Description

Technical Field

[0001] This utility model relates to the field of steel bar bending machine technology, and in particular to an automatic steel bar bending machine for construction. Background Technology

[0002] Reinforcing steel bars are steel bars used in concrete structures. They are usually high-strength steel with good tensile strength and corrosion resistance. They are mainly used to enhance the tensile strength of concrete. Reinforcing steel bars can effectively improve the tensile, compressive and bending strength of concrete. They can also increase the toughness of concrete structures, making them less prone to brittle fracture under stress.

[0003] During construction, steel bars that need to be bent are used in some areas, requiring a steel bar bending machine to process them. However, when bending steel bars, workers need to hold or press down on the other end of the steel bar, which increases the labor intensity of the workers and is prone to operational errors that can lead to injuries, thus reducing the effectiveness of the steel bar bending machine. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing equipment requires workers to hold or press down on the other end of the steel bar, which increases the labor intensity of workers, and proposes an automatic steel bar bending machine for construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic bending machine for building steel bars, comprising a bending machine body, two strip-shaped grooves opened at the top of the bending machine body, strip-shaped sliders movably embedded in the inner surface of each of the two strip-shaped grooves, a placement plate fixedly installed between the tops of the two strip-shaped sliders, two fixing frames fixedly installed at the top of the placement plate, electric push rods fixedly installed at the top of the inner walls of each of the two fixing frames, limit pressure plates fixedly installed at the output ends of each of the two electric push rods, two round holes opened at the top of each of the two fixing frames, limit rods movably inserted into the inner surface of each of the four round holes, and the bottoms of the four limit rods fixedly connected to the tops of the two limit pressure plates.

[0006] Preferably, the outer walls of the four limiting rods are all fixedly fitted with limiting rings, and the top of the bending machine body is fixedly installed with a flush block.

[0007] Preferably, a strip column is fixedly installed on the top of the bending machine body, and two fixing plates are fixedly installed on the top of the bending machine body.

[0008] Preferably, two fixing rods are fixedly installed on one side of the outer wall of each of the two fixing plates, and one side of the outer wall of each of the four fixing rods is fixedly connected to the opposite side of the outer wall of the strip column.

[0009] Preferably, two connecting plates are fixedly installed on the outer wall of the placement plate, and the inner walls of the two connecting plates are movably sleeved on the outer walls of the four fixed rods.

[0010] Preferably, two springs are fixedly installed on one side of the outer wall of each of the two connecting plates, and one side of the outer wall of each of the four springs is fixedly connected to the opposite side of the outer wall of the strip column. A bending assembly is provided on the top of the bending machine body.

[0011] Preferably, a controller is fixedly installed on the top of the bending machine body, and one side of the outer wall of the controller is electrically connected to the outer wall of the two electric push rods.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the reinforcing bar is placed on the placement plate and positioned at the corresponding position on the bending assembly. Then, the controller starts two electric push rods, which, under the action of four limit rods and four round holes, drive the two limit pressure plates to move downwards stably and clamp the reinforcing bar to be bent. Through the action of the four limit rings, the four limit rods can be prevented from disengaging from the four round holes.

[0016] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figures 1-4 As shown, this utility model provides an automatic bending machine for building steel bars, including a bending machine body 1. The top of the bending machine body 1 has two strip grooves 2. The inner surface of each of the two strip grooves 2 is movably embedded with a strip slider 3. A placement plate 4 is fixedly installed between the tops of the two strip sliders 3. Two fixing brackets 5 are fixedly installed on the top of the placement plate 4. Electric push rods 6 are fixedly installed on the top of the inner wall of each of the two fixing brackets 5. Limiting pressure plates 7 are fixedly installed at the output ends of each of the two electric push rods 6. Two round holes 8 are opened on the top of each of the four round holes 8. Limiting rods 9 are movably inserted into the inner surface of each of the four round holes 8. The bottom of each of the four limiting rods 9 is fixedly connected to the top of the two limiting pressure plates 7. Limiting rings 10 are fixedly sleeved on the outer surface of each of the four limiting rods 9. A flushing block 11 is fixedly installed on the top of the bending machine body 1.

[0019] The effect achieved by the entire embodiment 1 is as follows: the reinforcing bar is placed on the placement plate 4, and the reinforcing bar that needs to be bent at one end is placed on the bending component 17 and against the flush block 11. Then, the electric push rod 6 installed on the top of the inner wall of the two fixed frame 5 is activated by the controller 18. Since there are two round holes 8 on the top of the two fixed frames 5, and limit pressure plates 7 are installed at the output end of the two electric push rods 6, and the four limit rods 9 installed on the top of the two limit pressure plates 7 are movably inserted into the four round holes 8, the two electric push rods 6 can drive the two limit pressure plates 7 to move downward stably and limit one end of the reinforcing bar on the placement plate 4. Then, under the action of the four limit rings 10, the four limit rods 9 are effectively prevented from disengaging from the four round holes 8 and the two fixed frames 5. The operator does not need to hold or press the other end of the reinforcing bar to perform the bending operation, which reduces the labor intensity of the operator, improves the operation safety, and thus improves the use effect of the automatic bending machine for building reinforcing bars.

[0020] Example 2: As Figures 2-4 As shown, a strip column 12 is fixedly installed on the top of the bending machine body 1. Two fixing plates 13 are fixedly installed on the top of the bending machine body 1. Two fixing rods 14 are fixedly installed on one side of the outer wall of each of the two fixing plates 13. The outer walls of the four fixing rods 14 are fixedly connected to the opposite side of the outer wall of the strip column 12. Two connecting plates 15 are fixedly installed on the outer wall of the placement plate 4. The inner walls of the two connecting plates 15 are movably fitted onto the outer walls of the four fixing rods 14. Two springs 16 are fixedly installed on one side of the outer wall of each of the two connecting plates 15. The outer walls of the four springs 16 are fixedly connected to the opposite side of the outer wall of the strip column 12. A bending assembly 17 is provided on the top of the bending machine body 1. A controller 18 is fixedly installed on the top of the bending machine body 1. The outer wall of the controller 18 is electrically connected to the outer walls of the two electric push rods 6.

[0021] The overall effect of Embodiment 2 is that, through the action of the bending component 17, which includes a centrally fixed cylinder, a rotatable disk, a bending column, and a driving mechanism, the bending operation of the reinforcing bar can be completed. When the reinforcing bar is bent, it will also move forward a certain distance. Since the reinforcing bar is limited between the placement plate 4 and the two limiting pressure plates 7, and the two strip-shaped sliders 3 installed at the bottom of the placement plate 4 are movably embedded in the two strip-shaped grooves 2, the placement plate 4 can be driven to move forward a corresponding distance. Furthermore, since connecting plates 15 are installed on both sides of the placement plate 4, and two fixing rods 14 are installed between the strip-shaped column 12 and the two fixing plates 13, and Two connecting plates 15 are movably mounted on four fixed rods 14. Four springs 16 are installed between the two connecting plates 15 and the strip column 12, with each fixed rod 14 correspondingly located inside each spring 16. Thus, when the placement plate 4 moves, the two connecting plates 15 move on the four fixed rods 14, simultaneously compressing the four springs 16. This allows the machine to adapt to different forward movement distances and bending angles of the reinforcing bars, ensuring that the four springs 16 remain within a reasonable range of application. After the bending operation of the reinforcing bars is completed, the four springs 16 return to their original state, serving as a reset function and preparing for the next bending operation. This improves the efficiency of the automatic reinforcing bar bending machine.

[0022] Working principle: First, the rebar to be bent is placed on the placement plate 4, with the end to be bent resting against the flush block 11 and positioned appropriately on the bending assembly 17. Then, the controller 18 activates two electric push rods 6. Since the four limiting rods 9 installed on the top of the two limiting pressure plates 7 are movably inserted into the four round holes 8, the two limiting pressure plates 7 can move downwards stably, limiting the other end of the rebar. Then, the bending assembly 17 and the controller 18 automatically bend the rebar. At this time, under the action of the two strip sliders 3 and the two strip grooves 2, the placement plate 4 will move forward a certain distance with the rebar, thus allowing the placement plate 4 to bend. The connecting plates 15 installed on both sides simultaneously compress the four springs 16 between the two connecting plates 15 and the strip column 12. Under the action of the two fixed plates 13 and the four fixed rods 14, the linearity of the movement of the four springs 16 can be guaranteed, which can adapt to different distances of forward movement of the steel bar and different angles of bending of the steel bar. After the bending operation of the steel bar is completed, the four springs 16 return to their original state and are ready for the next bending of the steel bar. The operator does not need to hold the other end of the steel bar by hand to perform the bending operation, which reduces the labor intensity of the operator, improves the safety of operation, and thus improves the use effect of the automatic steel bar bending machine.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
