Description

Technical Field

[0001] This utility model relates to the field of steel bending technology, and in particular to a steel bending device with multi-angle adjustment. Background Technology

[0002] Steel bending is a processing technique that uses external force to cause plastic deformation of metal materials, thereby achieving the desired shape and angle. This technology is widely used in construction, machinery manufacturing, the automotive industry, and many other fields, and is one of the key steps in metal processing. The quality of bending directly affects the structural strength, appearance accuracy, and assembly performance of the product. With the development of industrial technology, higher demands are being placed on the precision, efficiency, and versatility of steel bending. Steel bending equipment occupies an important position in industries such as civil defense engineering and steel structure processing. As a core piece of equipment in key forming processes, its structural design and adjustment performance have a decisive impact on the overall processing effect, product quality, and operational safety. Especially in the core aspect of bending angle control, existing steel bending equipment has gradually revealed a series of obvious limitations and technical problems when handling steel of different specifications and materials.

[0003] Specifically, although the steel bending device disclosed in the existing utility model patent CN220717330U can achieve two bending of steel and improve the efficiency and positional accuracy of the second bending, its structural design is not convenient for flexible adjustment and limit control of the bending angle.

[0004] In practice, the lack of an effective angle adjustment and limiting mechanism easily leads to over-bending of steel or angle deviation, affecting the dimensional accuracy and performance of the final product. Furthermore, this structure is poorly adaptable to different processing requirements, making it difficult to meet the high-precision, multi-angle, and diversified bending demands of modern production. More seriously, these problems not only increase rework rates and production costs but may also pose potential safety hazards due to inaccurate angle control, impacting the overall project quality and schedule. Therefore, given the numerous shortcomings of existing technologies, we urgently need an innovative steel bending device to solve these problems. Utility Model Content

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 ,

[0023] A steel bending device with multi-angle adjustment includes a base 1, a top plate 2 fixedly connected to the top of the base 1, and a rotating rod 4 rotatably connected to the top of the base 1.

[0024] A bending plate 3 is sleeved on one end of the rotating rod 4, and a side plate 6 is fixedly connected to one side of the bending plate 3. A limit frame 15 is fixedly connected to one side of the side plate 6. A second motor 16 is fixedly connected to one side of the bottom of the base 1 by bolts. The bottom end of the rotating rod 4 passes through the base 1 and is connected to the output shaft of the second motor 16 for transmission. A ring gear 7 is slidably connected to one side of the top of the base 1. A fixing plate 10 is fixedly connected to one side of the base 1. A first motor 12 is fixedly connected to one side of the bottom of the fixing plate 10 by bolts. A connecting rod 11 is rotatably connected to the top of the fixing plate 10. The bottom end of the connecting rod 11 passes through the fixing plate 10 and is connected to the output shaft of the first motor 12 for transmission. The top end of the connecting rod 11 is meshed with the ring gear 7. A baffle 14 is fixedly connected to one side of the top of the ring gear 7.

[0025] First, the steel to be bent is inserted into the bending plate 3, and simultaneously extended further into the limiting frame 15 on one side of the side plate 6 to achieve effective positioning and clamping of the steel. Then, the second motor 16 is started, its output shaft driving the rotating rod 4 to rotate via transmission, thereby causing the bending plate 3, which is sleeved on one end of the rotating rod 4, to rotate synchronously, thus applying bending force to the steel and completing the initial bending action. At the same time, if it is necessary to adjust the bending angle or control the limit, the first motor 12 can be started, its output shaft driving the ring gear 7 to rotate via the connecting rod 11. The gear 7 and the connecting rod 11 are meshed, thus enabling precise angle transmission and rotation control. As the ring gear 7 rotates, the baffle 14 fixed on one side of its top also rotates. The baffle 14 is used to limit and guide the movement trajectory of the steel during bending, ensuring the accuracy and consistency of the bending angle. In addition, since the ring gear 7 can move flexibly on the top sliding connection structure of the base 1, together with the baffle 14, the device can adapt to the bending requirements of steel with different angles and specifications, and is easy to operate and has a wide adjustment range.

[0026] Furthermore, several sliders 8 are fixedly connected to the bottom of the ring gear 7, and all sliders 8 are slidably connected to the top of the base 1 through the annular groove 9. When the ring gear 7 slides on the top of the base 1, the multiple sliders 8 fixed at its bottom move along the trajectory of the annular groove 9. This structure enhances the stability and guidance of the ring gear 7 during its movement, preventing it from deviating or jamming, thereby improving the accuracy of the angle adjustment of the baffle 14 and the smoothness of its operation, and achieving the effect of improving the overall structural stability and adjustment accuracy of the device.

[0027] Furthermore, the top end of the rotating rod 4 is rotatably connected to the bottom of the top plate 2 via a rotating shaft, and the bottom end of the rotating rod 4 passes through the base 1 via a bearing sleeve. During the rotation of the rotating rod 4 driven by the second motor 16, this structure effectively supports the upper and lower ends of the rotating rod 4, ensuring its coaxiality and stability during rotation, reducing vibration or offset problems caused by uneven force, and achieving the effect of improving the smoothness of bending operation and the service life of the equipment.

[0028] Furthermore, a sleeve plate 18 is fitted onto the upper part of the rotating rod 4, and the top of the sleeve plate 18 is slidably connected to the bottom of the top plate 2. During the rotation of the bending plate 3 with the rotating rod 4, the sleeve plate 18 can slide along the top plate 2 to provide additional support, effectively sharing the lateral force borne by the rotating rod 4, preventing it from bending and deforming due to excessive force, thereby enhancing the rigidity and load-bearing capacity of the entire transmission system, and achieving the effect of improving the stability and load-bearing capacity of the device.

[0029] Furthermore, protrusions 5 are fixedly connected to both sides of the top of the sleeve plate 18, and both protrusions 5 are slidably connected to the bottom of the top plate 2 through the top groove 17. Through the cooperation of the protrusions 5 and the top groove 17, the protrusions 5 on both sides of the top of the sleeve plate 18 slide along the top groove 17 at the bottom of the top plate 2, which further restricts the freedom of the sleeve plate 18 in the horizontal direction, ensuring that it maintains good straightness and synchronization during the movement, thereby improving the consistency and accuracy of the action when the rotating rod 4 drives the bending plate 3 to bend the steel, and achieving the effect of enhancing the control accuracy of the bending action and the reliability of the equipment operation.

[0030] Furthermore, the bottom end of the connecting rod 11 passes through the fixed plate 10 via a bearing sleeve, and a gear disk 13 is fixedly connected to the top end of the connecting rod 11. The gear disk 13 is meshed with the ring gear 7. When the first motor 12 drives the connecting rod 11 to rotate, the gear disk 13 accurately transmits power to the ring gear 7, thereby achieving precise adjustment of the angle of the baffle 14. This structure not only improves the transmission efficiency but also enhances the response speed and accuracy of angle adjustment, achieving the effect of improving the accuracy of angle adjustment and the convenience of operation.

[0031] In summary:

[0032] First, the steel to be bent is inserted into the bending plate 3, and then further extended into the limiting frame 15 on one side of the side plate 6 to achieve effective positioning and clamping of the steel. Then, the second motor 16 is started, and its output shaft drives the rotating rod 4 to rotate via a transmission. The bottom end of the rotating rod 4 passes through the base 1 via a bearing sleeve and is connected to the output shaft of the second motor 16. The top end is rotatably connected to the bottom of the top plate 2 via a rotating shaft. This structure effectively supports both ends of the rotating rod 4, ensuring its coaxiality and stability during rotation, reducing vibration or offset problems caused by uneven force, thereby improving bending performance. The smoothness of operation and the service life of the equipment; as the rotating rod 4 rotates, the bending plate 3 sleeved at one end of it rotates synchronously, thereby applying bending force to the steel and completing the initial bending action; at the same time, if it is necessary to adjust or limit the bending angle, the first motor 12 can be started, and its output shaft drives the ring gear 7 to rotate through the connecting rod 11. The bottom end of the connecting rod 11 passes through the fixed plate 10 through the bearing sleeve, and the top end is fixed with a gear disk 13, which meshes with the ring gear 7. This structure makes the power transmission more precise and efficient, and improves the response speed and accuracy of angle adjustment; as the ring gear 7 rotates, The baffle 14 fixed on one side of its top also rotates accordingly, used to limit and guide the movement trajectory of the steel during bending, ensuring the accuracy and consistency of the bending angle; in addition, the ring gear 7 can move flexibly on the top sliding connection structure of the base 1, and several sliders 8 are fixedly connected to its bottom and are slidably connected to the top of the base 1 through the annular groove 9. When the ring gear 7 rotates, the sliders 8 slide along the annular groove 9, which enhances the guidance and stability during its movement, avoids deviation or jamming, and thus improves the accuracy of angle adjustment and the smoothness of operation; during the process of the bending plate 3 rotating with the rotating rod 4 To enhance the rigidity and load-bearing capacity of the overall structure, a sleeve plate 18 is fitted onto the upper part of the rotating rod 4. The top of the sleeve plate 18 is slidably connected to the bottom of the top plate 2, which can effectively share the lateral force borne by the rotating rod 4 and prevent it from bending and deforming due to excessive force. At the same time, protrusions 5 are fixedly connected to both sides of the top of the sleeve plate 18 and are slidably connected to the bottom of the top plate 2 through the top groove 17. This setting further restricts the degree of freedom of the sleeve plate 18 in the horizontal direction, ensuring that it maintains good straightness and synchronization during movement, thereby improving the consistency and accuracy of the action when the rotating rod 4 drives the bending plate 3 to bend the steel.Through the coordinated arrangement of the first motor 12, connecting rod 11, gear disk 13, ring gear 7, and baffle 14, precise adjustment and effective limiting of the bending angle are achieved, solving the problem of "inconvenience in flexibly adjusting and limiting the bending angle" in the prior art. This avoids excessive bending or angle deviation caused by angle loss of control, significantly improving processing accuracy. The arrangement of slider 8 and annular groove 9 enhances the stability and guiding performance of ring gear 7 during sliding, further improving the accuracy of angle adjustment and operational reliability. Thirdly, the rotating connection structure between the two ends of rotating rod 4 and top plate 2 and base 1 respectively, along with the application of bearing sleeves, gives rotating rod 4 higher coaxiality and stability during operation, reducing vibration and offset risks and extending equipment lifespan. Fourthly, the sliding connection structure between sleeve 18 and top plate 2 provides additional support points for rotating rod 4, effectively distributing the lateral force it bears, enhancing the rigidity and load-bearing capacity of the entire transmission system, thereby improving the stability and safety of equipment operation. Fifthly, the connection between protrusion 5 and top groove 17... The design further restricts the horizontal freedom of the sleeve 18, improving the consistency and control precision of the bending action and enhancing the reliability of equipment operation. Sixth, the synergistic effect between the limit frame 15, the bending plate 3, and the side plate 6 enhances the clamping stability of the steel, reducing shaking or offset during processing, thereby improving the consistency and reliability of bending quality. Seventh, the device has a compact overall structure and flexible adjustment methods, making it suitable not only for processing steel of various specifications and materials but also possessing good expandability, meeting the actual needs of modern production for high-precision, multi-angle, and diversified bending operations. Eighth, the linkage design between the second motor 16 and the rotating rod 4 simplifies the bending operation process, improves work efficiency, reduces the degree of manual intervention, and helps improve the overall automation level and operational safety of the equipment. Ninth, while improving processing efficiency, the device effectively reduces rework rates and material waste caused by angle errors, further controlling production costs and reducing potential safety hazards, ensuring product quality and project progress, and has good application prospects and promotional value.
