Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing equipment, in particular to a steel bar bender for construction projects. Background Technique

[0002] On construction sites, the consumption of steel bars is huge, and they are the foundation of building structures. As an indispensable equipment in steel bar processing, the steel bar bender can efficiently bend straight steel bars into required shapes to meet different construction needs. This machine not only improves the construction efficiency but also ensures the processing quality of steel bars, providing a strong guarantee for building safety and stability. After a large number of retrievals, the publication number is CN206716898U, which discloses a steel bar bender, solving the problems that the steel bars of the existing steel bar bender are prone to deflection and the bending accuracy of the steel bars is relatively low.

[0003] In the existing technology, when the device is in use, a force can be applied to the steel bar in one direction, so that the steel bar is bent, and the originally straight steel bar can be shaped into various complex bending forms by multiple bending methods to meet specific requirements in building structures. However, multiple bending of the steel bar requires repeated clamping and positioning of the steel bar. In the existing technology, for each angle of bending, the current steel bar needs to be re-clamped and positioned on one side, and these operations result in low working efficiency of steel bar bending. Therefore, a steel bar bender for construction projects is proposed. Content of the Utility Model

[0008] Preferably, an installation groove is formed in the middle of the upper surface of the base, and the bottom of the hydraulic cylinder is embedded and installed in the installation groove. In the design, an installation groove is ingeniously designed at the center of the upper surface of the base, enabling the bottom of the hydraulic cylinder to be embedded therein, achieving a compact layout and a stable installation.

The compact layout and stable installation improve the overall structural stability and durability.

[0009] Preferably, sliding rods are respectively and fixedly installed above the opposite sides of the two vertical rods. The two sliding rods are parallel to the vertical rods respectively. A first cross plate is fixedly installed on the opposite sides of the two vertical rods below the two sliding rods. The first cross plate is perpendicular to the two vertical rods. The height of the rear ends of the tops of the two vertical rods is higher than that of the front ends, and a top plate is fixedly installed. In the design, sliding rods are specially designed above the vertical rods. These sliding rods are parallel to the vertical rods. A first cross plate is provided below them, and the first cross plate is perpendicular to the vertical rods. At the same time, the height of the rear ends of the tops of the vertical rods is designed to be higher than that of the front ends and is connected and installed with a top plate, which facilitates the removal of the bent steel bar. The design of the sliding rods and the cross plate provides multi-directional support, enhancing the load-bearing capacity and operation flexibility of the machine.

[0010] Preferably, a hole is formed in the middle of the upper surface of the first cross plate and a limit sleeve is embedded and installed therein. The connecting rod passes through the limit sleeve. In the design, a hole is specially designed at the center of the upper surface of the first cross plate, and a limit sleeve is embedded inside. At the same time, the connecting rod is allowed to pass through it. This design ensures the precise positioning and stable movement of the connecting rod, providing an accurate guide for the bending of the steel bar. The accurate guide and positioning improve the accuracy and repeatability of the steel bar bending.

[0011] Preferably, a threaded hole is formed in the upper surface of the top plate, and an adjusting screw is threadedly installed in the threaded hole. A limit block is rotatably installed at the bottom of the adjusting screw. The lower surface of the limit block is parallel to the upper end surface of the steel bar body and contacts the steel bar body but is not fixedly connected. In the design, a threaded hole is carefully designed on the upper surface of the top plate and an adjusting screw is threadedly installed. A limit block is installed at the bottom of the adjusting screw.

The sliding groove design allows the second cross plate to flexibly adjust its position to adapt to the bending requirements of steel bars of different lengths and shapes, enhancing the adaptability of the machine and the convenience of operation.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

The middle section of the steel bar body is located in the groove below the first limiting wheel. The design of the groove allows the steel bar body to move smoothly between the limiting wheels while maintaining an accurate position. The hydraulic cylinder is fixed to the bottom of the second cross plate through a connecting rod. Operating the hydraulic cylinder can push the first limiting wheel downward to apply force, realizing the bending of the middle section of the steel bar body. When the first limiting wheel bends the middle section of the steel bar body, since the height of the second limiting wheels is higher than the bottom of the placement groove, they can simultaneously apply pressure to both ends of the steel bar body to realize the synchronous bending of both ends;

[0016] Since the bending of both ends and the middle section of the steel bar body are completed by the coordinated work of the limiting wheels and the hydraulic cylinder, the operator does not need to repeatedly clamp and position the steel bar body during the bending process, thus saving time and reducing labor intensity. By realizing multiple bends through one-time positioning, the design of the device in this application significantly improves the efficiency of steel bar processing, reduces production delays caused by repeated positioning. At the same time, the precise limiting wheel grooves and the control of the hydraulic cylinder ensure the consistency of the bending angle and position, improving the precision of steel bar processing, achieving the effect of realizing three bends with one-time positioning of the steel bar.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an embodiment provided by the present utility model: a steel bar bender for construction engineering, including a main body 1, and an adjustment component 5 is movably installed inside the main body 1; the main body 1 includes a base 11, and vertical rods 12 are respectively and fixedly installed on both sides of the upper surface of the base 11. Second limiting wheels 4 are respectively rotatably installed on the opposite sides of the two vertical rods 12 through first mounting brackets 15. Placement grooves 13 are opened at the tops of the two vertical rods 12, and the top height of the second limiting wheel 4 is higher than the bottom height of the placement groove 13;

[0025] The adjustment component 5 includes a second cross plate 53. A first limiting wheel 2 is rotatably installed at the middle rear end of the upper surface of the second cross plate 53 through a second mounting bracket 54, and a hydraulic cylinder 51 is fixedly installed at the middle of the bottom of the second cross plate 53 through a connecting rod 52;

[0026] The first limiting wheel 2 and the second limiting wheel 4 are of matching sizes, and grooves are opened in the middle of the edges of the first limiting wheel 2 and the second limiting wheel 4.

[0027] Specifically, the steel bar body 3 is placed in the placement groove 13 above the two second limiting wheels 4, and both ends of the steel bar body 3 are located in the grooves of the second limiting wheels 4. The middle section of the steel bar body 3 is located in the groove below the first limiting wheel 2. The design of the groove allows the steel bar body 3 to move smoothly between the limiting wheels while maintaining an accurate position. The hydraulic cylinder 51 is fixed to the bottom of the second cross plate 53 through the connecting rod 52. Operating the hydraulic cylinder can push the first limiting wheel 2 to apply a downward force, realizing the bending of the middle section of the steel bar body 3. When the first limiting wheel 2 bends the middle section of the steel bar body 3, since the height of the second limiting wheel 4 is higher than the bottom of the placement groove 13, they can simultaneously apply pressure to both ends of the steel bar body 3 to realize the synchronous bending of both ends;

[0028] Since the bending of both ends and the middle section of the steel bar body 3 are completed by the coordinated work of the limiting wheels and the hydraulic cylinder, the operator does not need to repeatedly clamp and position the steel bar body 3 during the bending process, thus saving time and reducing labor intensity. By realizing multiple bends through one-time positioning, the design of the device in this application significantly improves the efficiency of steel bar processing and reduces production delays caused by repeated positioning. At the same time, the precise limiting wheel grooves and the control of the hydraulic cylinder ensure the consistency of the bending angle and position, improving the precision of steel bar processing and achieving the effect of realizing three bends with one-time positioning of the steel bar.

This design not only saves space but also enhances the stability of the hydraulic cylinder 51, ensuring accurate operation even under high loads.

At the same time, the height of the rear end of the top of the vertical rods 12 is designed to be higher than that of the front end and a top plate 14 is connected and installed, which provides convenience for taking out the bent steel bars. The design of the sliding rods 16 and the cross plate provides multi-directional support, enhancing the bearing capacity of the machine and the flexibility of operation.

[0032] Further, a central hole is formed on the upper surface of the first cross plate 17 and a limiting sleeve 101 is embedded and installed. The connecting rod 52 passes through the limiting sleeve 101. In the design, a hole is specially designed in the center of the upper surface of the first cross plate 17 and a limiting sleeve 101 is embedded inside. At the same time, the connecting rod 52 is allowed to pass through it. This design ensures the precise positioning and stable movement of the connecting rod 52, providing precise guidance for steel bar bending. The precise guidance and positioning improve the accuracy and repeatability of steel bar bending.

[0033] Further, screw holes 102 are formed on the upper surface of the top plate 14. Adjusting screws 104 are threadedly installed in the screw holes 102. A limiting block 105 is rotatably installed at the bottom of the adjusting screw 104. The lower surface of the limiting block 105 is parallel to the upper end surface of the steel bar body 3 and contacts the steel bar body 3 but is not fixedly connected. In the design, screw holes 102 are carefully designed on the upper surface of the top plate 14 and adjusting screws 104 are threadedly installed. A limiting block 105 is installed at the bottom of the adjusting screw 104.

[0035] Embodiment III

[0036] To improve the stability of the equipment when bending steel bars, as Figure 1 and Figure 3 shown, in this embodiment, chutes 501 are respectively opened on both sides of the upper surface of the second cross plate 53. Two slide bars 16 respectively pass through the chutes 501. The second cross plate 53 is parallel to the first cross plate 17, and both ends of the second cross plate 53 are in contact with but not fixedly connected to the vertical rods 12. In the design, chutes 501 are designed on both sides of the upper surface of the second cross plate 53, and the slide bars 16 pass through these chutes 501, enabling the second cross plate 53 to move flexibly. The second cross plate 53 is parallel to the first cross plate 17, and both ends are in contact with but not fixedly connected to the vertical rods 12, providing an additional degree of freedom for adjustment. The design of the chutes 501 allows the second cross plate 53 to flexibly adjust its position to adapt to the bending requirements of steel bars of different lengths and shapes, enhancing the adaptability of the machine and the convenience of operation.

[0037] When the present utility model is in use, ensure that all components of the steel bar bender are intact. Place the steel bar body 3 in the placement groove 13, ensure that both ends of the steel bar body 3 are located above the second limit wheels 4 and are in the grooves of the second limit wheels 4, and make the middle section of the steel bar body 3 located above the first limit wheels 2 and in the grooves of the first limit wheels 2. By adjusting the adjusting screw 104 in the screw hole 102 of the top plate 14, the limit block 105 is moved downward to clamp and position both ends of the steel bar body 3. At this time, according to the shape of the steel bar to be bent, operate the hydraulic cylinder 51 to pull the first limit wheels 2 on the second cross plate 53 downward, thereby realizing the bending of the middle section of the steel bar body 3. At the same time, under the action of the two second limit wheels 4, both ends of the steel bar body 3 can be bent synchronously, and thus the first bending is carried out in this way. When the steel bar body 3 reaches the required shape, reset the hydraulic cylinder 51 and adjust the adjusting screw 104, and then take out the bent steel bar body 3 from the front end below the top plate 14. After use, clean the debris and oil stains on the steel bar bender and perform necessary maintenance and upkeep on the machine.
