[0002] In modern building installation projects, lightning protection and grounding is an important safety measure, especially indispensable in large public facilities such as airports. The traditional lightning protection and grounding system usually uses the steel bars in the main structure of the building as down conductors, and connects them to the underground grounding grid through metal components such as grounding round steel to ensure that lightning current can be quickly introduced into the ground and prevent lightning strikes from damaging the building and its internal equipment.

[0003] Among them, manufacturing the crossover bend of grounding round steel is a key step, which involves bending the straight grounding round steel into a specific shape to meet the installation requirements of different parts. The traditional manual method is not only inefficient, but also because of repeated manual bending, it is difficult to unify the size and shape of the crossover bend, thus affecting the overall installation quality and construction progress.

[0004] In view of the above problems, there is an urgent need for a new solution to improve the manufacturing speed and quality of the crossover bend of grounding round steel to meet the needs of modern building projects. Therefore, the utility model aims to provide a device for quickly manufacturing the crossover bend of grounding round steel, which can significantly improve work efficiency, ensure product consistency, and at the same time reduce the labor intensity of workers. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a device for manufacturing the crossover bend of grounding round steel, which can improve the bending efficiency and increase the bending accuracy.

[0008] A forming die, which is arranged at the top of the support mechanism.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0033] As shown Figures 1 to 5 in the figure, a device for fabricating a grounding round steel crossover bend of the present utility model includes:

[0034] A support mechanism 1, which is independently and fixedly arranged, usually placed on the ground, and can be connected and fixed to the ground when necessary;

[0035] A forming die 2, arranged at the top of the support mechanism 1. The inside of the forming die 2 is set as a cavity structure, and through holes are respectively arranged at both ends of the cavity structure in the length direction. The through holes are used for the grounding round steel to pass through;

[0036] Two bending members 3, both arranged in the cavity structure and distributed along the length direction of the cavity structure, used to control the bending size and position of the grounding round steel;

[0037] A top bender 4, arranged at the bottom of the forming die 2 and between the two bending members 3; the top bender 4 slides relative to the support mechanism 1, and the sliding track is perpendicular to the length direction of the forming die 2; the top bender 4 is driven by a jack to move up and down;

[0038] A positioning mechanism 5, symmetrically arranged at both ends of the forming die 2, used for the placement and positioning of the grounding round steel during bending.

[0039] The specific working process of this device is as follows:

[0040] Before bending the grounding round steel, first move the top of the top bender 4 to a position lower than the bending member 3, so that a gap is formed between the top of the top bender 4 and the bending member 3; the operator passes the grounding round steel through the cavity structure of the forming die 2. Inside the cavity structure, the grounding round steel will enter the gap between the top of the top bender 4 and the bending member 3. Then, the grounding round steel is positioned by the positioning mechanism 5. At this time, the preparation work for bending is completed.

[0041] When bending the grounding round steel, start the jack, and drive the top bender 4 to rise smoothly through the hydraulic system until the top of the top bender 4 moves to a position higher than the bending member 3. At this time, the top bender 4 pushes the grounding round steel upward, so that it forms the required bent shape under the action of the bending member 3. When the grounding round steel is completely bent according to the preset angle and size, stop the action of the jack, so that the top bender 4 stops rising, lower the top bender 4 to the initial position, and prepare for the next bending. The bent grounding round steel can be taken out from the through hole of the forming die 2.

[0042] Through this device, the one-time forming of the grounding round steel crossover bend can be achieved, greatly reducing the number of repeated actions required for manual bending. Compared with the traditional method, this device significantly improves the production efficiency. This device controls the bending size and position of the grounding round steel through the precisely designed forming die 2 and the bending part 3, ensuring the consistency of the crossover bends produced each time in terms of size and shape. The traditional manual bending method requires workers to exert force repeatedly, which is prone to causing physical fatigue. The device of the utility model uses a hydraulic jack to drive the bending jack 4 to move up and down, which not only simplifies the operation process but also significantly reduces the physical burden on workers. Since this device can significantly shorten the production time of a single crossover bend, the progress of the entire construction project is accelerated. This device can also save costs by reducing the labor input and the probability of rework caused by product quality problems. The operation of this device is simple and intuitive. The positioning mechanism 5 is symmetrically arranged at both ends of the forming die 2, ensuring the accuracy of the placement of the grounding round steel, facilitating workers to quickly master the usage skills, and reducing the training time and the probability of errors.

[0043] As Figures 1 to 5 shown, as a preferred solution, the support mechanism 1 includes:

[0044] Support legs 11, with the top fixedly connected to the bottom of the forming die 2, used to support the forming die 2;

[0045] Base 12, fixedly connected to the bottom ends of the support legs 11; the base 12 is used to place the jack. The length direction of the base 12 is parallel to the length direction of the forming die 2. Multiple auxiliary legs 13 extending along the width direction of the base 12 are arranged at both ends of the base 12, used to improve the balance of the support mechanism 1. Support columns 14 are arranged on each of the auxiliary legs 13, and the top ends of the support columns 14 are all fixedly connected to the support legs 11, used to improve the rigidity of the support mechanism 1. By setting the base 12 and arranging multiple auxiliary legs 13 at both ends of the base, the balance of the overall device of the support mechanism 1 is significantly enhanced. This enables the entire device to remain stable during the processing, not prone to displacement or tilt even when the bending jack 4 makes frequent up and down movements. The support columns 14 arranged on the auxiliary legs 13 further strengthen the structural strength of the support legs 11, enabling the support mechanism 1 to have high rigidity. This high rigidity not only helps to resist the external force influence during the processing but also ensures that the forming die 2 can still maintain its original accuracy after long-term use. Since the overall design of the support mechanism 1 is reasonable and the connection between components is firm and reliable, the service life of this device is effectively extended. The stable support mechanism 1 provides a safer working environment for the operator, reduces the potential safety hazards that may occur during the operation of the equipment, and guarantees the personal safety of the staff.

[0046] As Figures 1 to 5As shown, as an optimal solution, a positioning clamping plate 6 is provided on the base 12 for restricting the position of the jack. The positioning clamping plate 6 is located on the moving track of the bending device 4. The setting of the positioning clamping plate 6 can ensure that the jack is accurately placed at the specified position, preventing problems such as unstable or inaccurate movement of the bending device 4 caused by the deviation of the jack position, avoiding safety accidents caused by accidental movement of the jack during the operation of the bending device 4, and providing a safer working environment for the operator.

[0047] The positioning mechanism 5 can be implemented in various existing ways such as clamping jaws and bolts. However, in order to facilitate the operation of personnel more conveniently, a more optimal positioning mechanism 5 is proposed for this device, including:

[0048] Two slot supporting plates 51 are respectively arranged at the through holes at both ends of the forming die 2;

[0049] Two positioning slots 52 are respectively arranged on a corresponding slot supporting plate 51; multiple groups of V-shaped positioning slots are arranged on each positioning slot 52, and the V-shaped positioning slots are used for positioning the grounding round steel. The V-shaped positioning slots on the positioning slot 52 enable the operator to quickly find the correct placement point, simplify the positioning process of the grounding round steel, reduce the operation difficulty, so that even a novice can quickly get started. Through the precise positioning function of the positioning mechanism 5, the preparation time before each bending can be significantly reduced, the production speed of a single cross-connection bend can be accelerated, and multiple grounding round steels can be bent simultaneously by the device through the setting of multiple groups of V-shaped positioning slots.

[0050] As Figures 1 to 5 shown, as an optimal solution, a pressing handle 7 is arranged in the fixing hole opened on the bending device 4, and the length direction of the pressing handle 7 is perpendicular to the moving track of the bending device 4. The design of the pressing handle 7 enables the operator to easily control the lifting of the bending device 4. Especially after the bending is completed, the bent grounding round steel may get stuck in the bending device 4, making it unable to smoothly retract with the jack. At this time, the operator only needs to press down the pressing handle 7 to conveniently assist the downward reset of the bending device 4; at the same time, the pressing handle 7 can also limit the moving stroke of the bending device 4.

[0051] As Figures 1 to 5 shown, as an optimal solution, a guiding member 8 is arranged at the bottom of the forming die 2, and a through hole is arranged on the guiding member 8. The bending device 4 is slidably arranged in the through hole. The through hole on the guiding member 8 provides an accurate sliding path for the bending device 4, ensuring that the bending device 4 can move smoothly along the predetermined track during the lifting process, reducing the processing error caused by deviation or shaking, and improving the product quality.

[0052] A device for fabricating a grounding round steel cross-bend of the utility model has an installation method, a connection method or a setting method that are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0053] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the utility model.
