[0002] In the metal processing industry, steel bars, as a commonly used raw material, often need to be bent into various shapes to adapt to different product designs. Traditional steel bar bending methods mostly involve manual bending or simple die stamping. Manual bending is not only inefficient, but also makes it difficult to ensure consistent bending angles and results in poor precision, failing to meet the production requirements of high-precision products. While simple die stamping improves production efficiency to some extent, die replacement and adjustment are complex and costly, and different dies are required for steel bars of different specifications and bending angle requirements, resulting in poor flexibility.

The fixed platform is mounted on the base and has two limiting posts. The steel bar is placed between the two limiting posts. The rotating component is sleeved on the fixed platform and can rotate on the fixed platform. The rotating component has a stop post. When the rotating component is rotated, the stop post abuts against the steel bar, causing it to rotate and bend. The base has a positioning component, and the rotating component has a limiting block. When the rotating component rotates to a preset angle, the positioning component abuts against the limiting block, limiting the rotation of the rotating component.

[0026] This utility model proposes a steel bar bending device 100.

[0027] Please see Figures 1-5 In one embodiment of this utility model, the steel bar bending device 100 includes a base 10, a fixed platform 20, and a rotating component 30. The fixed platform 20 is disposed on the base 10 and is provided with two limiting posts 21. The steel bar is placed between the two limiting posts 21. The rotating component 30 is sleeved on the fixed platform 20 and can rotate on the fixed platform 20. The rotating component 30 is provided with abutting posts 33. When the rotating component 30 is rotated, the abutting posts 33 abut against the steel bar, causing it to rotate and bend. The base 10 is provided with a positioning component 50, and the rotating component 30 is provided with a limiting block 35. When the rotating component 30 rotates to a preset angle, the positioning component 50 abuts against the limiting block 35 to limit the rotation of the rotating component 30.

[0028] In this embodiment, the base 10 can be fixed to the workbench by means of screws or bolt nuts. The detachable method facilitates the carrying of the entire device and is convenient for disassembly and assembly. Among them, the fixing table 20 is circular from a top view and in an inverted "convex" shape from a front view. The two limiting columns 21 are perpendicularly arranged on the upper surface of the fixing table 20, and the two limiting columns 21 are arranged at intervals to ensure that there is enough distance between them to place the steel bar.

[0029] It can be understood that the fixing table 20 is stationary, and the rotating member 30 can rotate on the fixing table 20. Place the steel bar between the two limiting columns 21, and then rotate the rotating member 30. The abutting column 33 abuts against the steel bar to make it rotate. The steel bar bends under the limitation of the two limiting columns 21. When the rotating member 30 rotates to a preset angle, the positioning member 50 abuts against the limiting block 35 to limit the rotating member 30, ensuring that the steel bar can be bent to an accurate angle.

[0030] In an embodiment of the present invention, the rotating member 30 includes a connecting ring 31 and an operating rod 32. The connecting ring 31 is sleeved on the fixing table 20, and the operating rod 32 is arranged on the outer side wall of the connecting ring 31, facilitating the operator to apply force to rotate the rotating member 30. The abutting column 33 is arranged on the operating rod 32. A limiting groove 22 is provided on the fixing table 20, and a limiting platform 34 is provided on the connecting ring 31. The limiting platform 34 is stuck in the limiting groove 22.

[0031] In this embodiment, the limiting groove 22 is close to the base 10 and is located at the bottom of the fixing table 20. The limiting platform 34 is stuck in the limiting groove 22 in the form of a buckle. This structural design can effectively limit the axial movement of the rotating member 30 during rotation, ensure the stability and accuracy of the rotation of the rotating member 30, and prevent the connecting ring 31 from disengaging from the fixing table 20 during rotation. Among them, a ball bearing 40 is provided between the limiting platform 34 and the limiting groove 22. The setting of the ball bearing 40 can reduce the friction between the limiting platform 34 and the limiting groove 22, make the rotation of the rotating member 30 smoother, reduce the labor intensity of the operator, and also reduce the wear between components, improving the service life of the device. It should be noted that a recess 36 is provided on the abutting column 33, and a rubber pad can be provided at the recess 36 to increase the friction with the steel bar and thus improve the traction force.

[0032] In one embodiment of this utility model, the base 10 has a plurality of positioning holes 11, which are arranged along the arc surface of the connecting ring 31, and the positioning member 50 is engaged in one of the positioning holes 11. The inner wall of the positioning hole 11 has a slot 12 and a sliding groove 13, which are connected. The positioning member 50 has a boss 51, which can enter the slot 12 from the sliding groove 13.

[0033] In this embodiment, the outer diameter of the slot 12 is larger than the inner diameter of the positioning hole 11, and the sliding groove 13 is perpendicular to the slot 12. It is understood that the boss 51 slides into the sliding groove 13, allowing the positioning member 50 to be inserted into the positioning hole 11. When the positioning member 50 abuts against the bottom of the positioning hole 11, the boss 51 is precisely located in the slot 12. Rotating the positioning member 50 at this point displaces the boss 51 from the sliding groove 13, thus improving the stability of the positioning member 50 and preventing it from easily detaching from the positioning hole 11. When it is necessary to insert the positioning member 50 into positioning holes 11 at different positions, first rotate it to align the boss 51 with the sliding groove 13, and then remove the positioning member 50.

[0034] It should be noted that the spacing between the positioning holes 11, as well as the number and size of the positioning holes 11, can be set according to the actual use. The accompanying drawings in this application are only for illustration purposes, and the specific parameters can be adjusted according to the actual application.

[0035] By engaging the positioning element 50 with the positioning holes 11 at different positions, different rotation angles of the rotating element 30 can be restricted, thereby meeting the requirements for different bending angles of the steel strip. Furthermore, when the limiting block 35 abuts against the positioning element 50, the bending is complete. This ensures that the bending angle is consistent each time, enhancing the versatility of the device and reducing the cost and time of changing molds due to different bending angle requirements.

[0036] Working principle: The steel bar to be bent is placed between the two limiting posts 21 of the fixed platform 20. The two limiting posts 21 initially position the steel bar to ensure accurate positioning for subsequent bending operations. The operator then holds the operating rod 32 and applies force to rotate the rotating component 30, causing it to rotate on the fixed platform 20. As the rotating component 30 rotates, the abutting post 33 gradually abuts against the steel bar, pushing it to rotate and thus bending it. During the rotation of the rotating component 30, when it reaches a preset angle, the limiting block 35 on the rotating component abuts against the positioning component 50 on the base 10. At this point, the rotating component 30 cannot continue to rotate, and the steel bar is bent to the preset angle. If the bending angle needs to be adjusted, the positioning component 50 is removed from the corresponding positioning hole 11 and then inserted back into the positioning hole 11 corresponding to the desired bending angle, and the bending operation is performed again.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
