Description

TECHNICAL FIELD

[0001] The present application relates to a bending device, in particular to an improved multifunctional steel bending device, belonging to the technical field of building construction. BACKGROUND

[0002] Generally speaking, in part of the building lightning protection engineering, galvanized flat steel or round steel is often used as grounding trunk and lightning strip in distribution box, roof, etc., when the turning place along the building shape is needed, the round steel needs to be bent, because the hardness of large specification round steel is high, it is difficult to bend, the traditional construction adopts the method of cutting off at the turning place and re-welding connection, which greatly increases the lightning resistance and increases the construction cost and the forming appearance quality. Especially in the lightning protection construction of the building with complex shape using galvanized round steel as lightning strip, all the turning places are connected by welding, the welding engineering quantity is huge, and the overlapping height of the lightning strip increased by the lap joint of flat steel affects the appearance of the building.

[0003] Therefore, in many construction processes, in the lightning protection grounding operation of the building, the steel bar needs to be bent to ensure the grounding quality and the aesthetic effect. In order to facilitate, when bending the steel bar, the steel bar is usually bent manually by using pliers or other tools, because the manual processing precision is poor, the bending deformation radius will produce different radius deformation due to different stress, and the bending angle of the steel bar often does not meet the requirements or the bending position has a large error, which not only reduces the bending efficiency, but also affects the use due to the unsatisfactory bending effect. This way not only wastes manpower and financial resources, but also often fails to meet the requirements.

[0004] In summary, the traditional steel bending device may have the following shortcomings in actual application:

[0005] First, rigidity limitation: the rigidity of the steel bending device may be limited, which cannot adapt to the bending requirements of steel bars of specific shapes or sizes. Some complex-shaped steel bars may need other special processing equipment or manual operation to complete.

[0006] Second, limited adaptability: the steel bending device is usually designed and manufactured according to specific sizes and shapes of steel bars, and its adaptability is limited. When multiple specifications of steel bars need to be processed, the clamps, molds and other parts may need to be replaced or adjusted, increasing the complexity and time cost of operation.

[0007] Third, low production efficiency: since the steel bending device usually completes the bending of one steel bar at a time, for large quantities of steel bar processing requirements, it may take a long time and human resources. This may affect the production efficiency and capacity.

[0008] Fourth, the operation requires high: using steel bending device for steel bending processing needs experienced operators, they need to be familiar with the operation process of the equipment, parameter setting and safety precautions, etc. For beginners or unfamiliar with the operation of the equipment, it may need longer learning and adaptation period.

[0009] Five, the cost of equipment is higher: steel bending device is usually a special equipment, its manufacturing and purchase cost is relatively high. This may exist certain economic pressure for small-scale steel processing enterprises or individual craftsmen.

[0010] More importantly, since in use, there is no corresponding limit structure to protect the operator or other people around during steel processing, it is difficult to ensure the safety of the operator during use, and it is impossible to prevent the device from exceeding the specified range during bending, which may cause accidents. During operation, the safety is low. In short, it is often very inconvenient. At present, the existing structure has never set up the function of protection of the corresponding structure, which may cause safety hazards during use.

[0011] In short, steel bending device has its advantages in steel processing field, but also has some shortcomings. When choosing to use the device, production demand, cost investment and technical requirements should be considered.

[0012] At present, the Chinese invention patent with the publication number CN214768036U discloses an improved round steel bending device, which comprises a base (1), support columns (2), steel processing components (3) and driving equipment (4). The base (1) is symmetrically provided with support columns (2) on the top, and steel processing components (3) are vertically arranged on the top of the two support columns (2). The middle part of the steel processing component (3) is provided with a hollow area (31), and limit pieces (5) are symmetrically arranged on the top of the hollow area (31). The limit pieces (5) and the hollow area (31) form a forming area for round steel processing. The driving equipment (4) is placed below the hollow area (31) and is detachably connected to the base (1) through a bolt assembly (6). Ring-shaped lugs (32) are symmetrically arranged on the top of the steel processing component (3). Although the round steel bending device of this structure can realize the bending of round steel, it can only bend one steel at a time during the bending process, and cannot simultaneously bend multiple steels at a time, resulting in low bending efficiency, bending error, time-consuming and labor-intensive operation, and large differences between the bent steels, which cannot guarantee the processing quality and precision. In short, it is often very inconvenient.

[0013] Therefore, developing an improved multifunctional reinforcing steel bar bending device with high efficiency and high precision is the key to solve the above technical problems. SUMMARY

[0016] Another object of the present application is to provide a push-pull handrail for facilitating the movement of the device by the operator, and the push-pull handrail is rotatably connected to the operating table, also serving as a space-saving function; the device is also provided with moving wheels, which facilitate movement and reduce the physical labor of the operator, and the moving wheels are provided with brake devices to increase safety and better fix the device.

[0140] An improved multifunctional steel bar bending device of the above design structure needs to be installed at the designated working position as standby before use by manually or corresponding handling equipment.

[0141] The specific installation steps are:

[0142] Firstly, the operator connects and locks the bending head 4, which is adapted to the radius of the steel bar to be bent, at the working end of the electric telescopic device 32 according to the radius of the steel bar to be bent;

[0145] Then, the operator respectively fixes and connects the transmission equipment 3 and the control equipment 5 on the operation table 1; and the device can be used.

[0146] The specific use steps are:

[0147] When using, the operator first moves or carries the device to the processing site;

[0148] Then, the operator adjusts the distance between the two placement racks 21 according to the radius and distance of the steel bar to be bent, and adjusts the distance according to the scale line set on the outside of the sliding groove 11, so that the distance between the two placement racks 21 and the center axis is consistent, and the quality of the bent product is increased. After the distance between the two placement racks 21 is adjusted and determined, the distance is fixed by the jacking piece 25 below each placement rack 21;

[0151] Finally, the operator loosens the jacking piece 25, fine-tunes the two placement racks 21, starts the control equipment 5, and drives the electric telescopic device 32 to move towards the steel bars 10, thereby driving the bending head 4 connected with the electric telescopic device 32 to bend the steel bars 10 between the two placement racks 21. After the bending work is completed, the placement device 2 at one end is moved, and the steel bars 10 on the device are collected, and the bending work of the steel bars is completed.

[0152] The above operations are repeated in sequence until all the steel bars to be bent are completed.

[0153] Finally, over time, after the completion of the reinforcement 10 bending, the operator only needs to clean or repair the present application, and again through artificial or corresponding handling equipment to be transported to the designated tool storage warehouse for storage, in preparation for the next cycle of use.
