Description

Technical Field

[0001] This utility model relates to the field of material forming technology, and in particular to a bending and forming device for round steel crossover wires. Background Technology

[0002] In lightning protection grounding projects both inside and outside buildings, bridging round steel is introduced into the soil and forms a unified grounding system with a large contact area with a conductive material. This system, with conductivity matching that of the surrounding terrain and buildings, leads the building into a large underground grounding electrode. To improve strength and prevent corrosion from affecting lifespan, the bridging round steel needs to be bent.

[0003] Chinese patent document CN205289375U discloses a round steel bending device, which includes a base rod with a clamping groove for bending round steel fixed on the base rod. Fixed supports are fixed at both ends of the base rod. When in use, one end of the round steel needs to be placed in the clamping groove and a force is applied to the other end of the round steel. After three bends, the middle section of the round steel can be bent into an "Ω" shape.

[0004] This type of round steel bending device requires manual determination of the bending position and angle each time it bends. There are no limiting devices for the bending position and angle. This method requires three bending processes to complete the bending and forming of the round steel jumper wire. It is easy to over-bend or under-bend, which affects the quality of the round steel jumper wire. Especially in the case of a large number of bending operations, the work efficiency is low, the manual operation is difficult and labor-intensive, and it cannot meet the requirements of rapid construction. Utility Model Content

[0005] The purpose of this utility model is to provide a round steel jumper wire forming device, which makes the round steel jumper wire bending and forming operation convenient, the forming consistency is high, and the bending and forming efficiency and the quality of the round steel jumper wire are improved.

[0006] To solve the above-mentioned technical problems, the embodiments of this utility model provide a technical solution as follows:

[0007] A round steel crossover wire bending and forming device includes a base and a pressure rod. One end of the pressure rod is hinged to the base. A support rod is slidably connected to the base on both sides of the pressure rod. The support rods are arranged in parallel. The two support rods are provided with corresponding slots. The slots are coaxially arranged. The rotation plane of the pressure rod is perpendicular to the axis of the slot.

[0008] Furthermore, the support rod is provided with a limiting piece corresponding to the slot, the limiting piece is located in the opening direction of the slot, and the corresponding limiting pieces are located on the same horizontal plane.

[0009] Furthermore, the limiting plate and the support rod are detachably fixed.

[0010] Furthermore, the base is provided with a first sliding groove, and the end of the support rod is slidably connected to the same side of the base through the first sliding groove. The other side of the base opposite to the support rod is provided with a fastener, which can pass through the first sliding groove to fix the support rod to the base.

[0011] Furthermore, it includes a limiting rod, which is arranged parallel to the base. The limiting rod has a second sliding groove. One end of the support rod is slidably connected to the limiting rod through the second sliding groove. The other side of the limiting rod opposite to the support rod is provided with a fastener, which can pass through the second sliding groove to fix the support rod to the base.

[0012] Furthermore, the limiting rod is provided with a groove corresponding to the pressure rod, and the groove can limit the pressure rod in the direction of rotation.

[0013] Furthermore, the length of the pressure rod is greater than the distance between the base and the limiting rod.

[0014] This utility model provides a round steel jumper bending and forming device. Compared with the prior art, it achieves bending deformation of the round steel at three points: the contact point between the round steel and the pressure rod, and the contact points between the two ends of the round steel and the support rod, through the hinged connection between the pressure rod and the base and the support rods arranged parallel to both sides of the pressure rod. The force applied to the round steel by the rotation of the pressure rod around the hinge axis allows the round steel to be bent and formed in one step to produce the required round steel jumper. The operation is simple, the forming consistency is high, and it is beneficial to improve the bending forming efficiency and the quality of the round steel jumper. The sliding connection between the support rod and the base allows the distance between the two support rods to be adjusted, thereby obtaining bending angles with different arc lengths and bending radii, which can meet the different bending forming requirements of the round steel jumper. The setting of the limiting plate ensures that the two ends of the round steel remain horizontal during bending, which can quickly and efficiently produce "Ω" shaped round steel jumpers. The setting of the limiting rod and the groove further ensures the consistency and stability of the round steel bending forming. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0022] like Figure 1-4As shown. In one embodiment of this utility model, a round steel jumper wire bending forming device is provided, including a base 1 and a pressure rod 3. One end of the pressure rod 3 is hinged to the base 1, and the pressure rod 3 can rotate relative to the base 1 about the hinge shaft 12. A support rod 2 is slidably connected to the base 1 on both sides of the pressure rod 3. The support rods 2 are arranged in parallel, and the two support rods 2 are provided with corresponding slots 21. The slots 21 are open grooves, and the cross-section of the slots 21 is any one of U-shape, V-shape, and arc shape. The slots 21 are coaxially arranged, and the rotation plane of the pressure rod 3 is perpendicular to the axis of the slots 21. The slot 21 is used for positioning and placing the round steel. The round steel is placed in the slot 21, and a force is applied to the end of the pressure rod 3 away from the hinge shaft 12, causing the pressure rod 3 to move towards the round steel. The contact point between the pressure rod 3 and the round steel is the point of force application. This point of force application is located between the contact points of the two slots 21 and the round steel. By continuing to apply force to the pressure rod 3, the round steel undergoes bending deformation, thus bending and forming the round steel jumper. This process is convenient, produces high consistency, and improves bending efficiency and the quality of the round steel jumper. By adjusting the distance between the two parallel support rods 2, the arc length and bending radius of the bent portion of the round steel jumper can be adjusted to meet the bending and forming requirements of round steel jumpers of different specifications. In an exemplary example, the base 1 is provided with a first sliding groove 11, and the end of the support rod 2 is slidably connected to the same side of the base 1 through the first sliding groove 11. The other side of the base 1 opposite to the support rod 2 is provided with a fastener 6, which can pass through the first sliding groove 11 to fix the support rod 2 to the base 1. After the distance between the two support rods 2 is adjusted to the correct position, the support rod 2 is fixed to the base 1 by the fastener 6, which ensures the stability of the distance between the support rods 2 during the bending process and helps to ensure the consistency of the round steel bending. Preferably, the fastener 6 can be a bolt or a screw with a locking nut.

[0023] In one embodiment, a round steel jumper wire bending and forming device is provided. The support rod 2 is provided with a limiting piece 4 corresponding to the slot 21. The limiting piece 4 is located in the opening direction of the slot 21. The corresponding limiting pieces 4 are located on the same horizontal plane and parallel to the axis of the slot 21. In use, both ends of the round steel are inserted between the slot 21 and the limiting piece 4. When the round steel is bent under the force of the pressure rod 3, both ends of the round steel are restricted by the limiting piece 4, maintaining a horizontal state, thereby obtaining an "Ω" shaped round steel jumper wire. Preferably, the limiting piece 4 and the support rod 2 are detachably fixed. When a V-shaped round steel jumper wire is needed, the limiting piece 4 can be removed, keeping the slot 21 in an open state, and the distance between the parallel support rods 2 can be adjusted to obtain different bending angles.

[0024] like Figure 2As shown, in one embodiment, a round steel jumper wire bending and forming device is provided, including a base 1 and a pressure rod 3. One end of the pressure rod 3 is hinged to the base 1, and the pressure rod 3 can rotate relative to the base 1 about the hinge shaft 12. It also includes a limiting rod 5, which is arranged parallel to the base 1. The length of the pressure rod 3 is greater than the distance between the base 1 and the limiting rod 5. Two support rods 2 are arranged parallel to the limiting rod 5 and the base 1. The limiting rod 5 has a second sliding groove 51. One end of the support rod 2 is slidably connected to the base 1 through a first sliding groove 11, and the other end of the support rod 2 is connected to the limiting rod 5 through the second sliding groove 51. A sliding connection is used. On the opposite side of the limiting rod 5 and the support rod 2, a fastener 6 is provided. The fastener 6 passes through the second sliding groove 51 to fix the support rod 2 to the base 1. On the opposite side of the base 1 and the support rod 2, a fastener 6 is provided. The fastener 6 passes through the first sliding groove 11 to fix the support rod 2 to the base 1. After the distance between the two support rods 2 is adjusted to the correct position, the fastener 6 is used to fix the support rod 2 to the base 1 and the support rod 2 to the limiting rod 5. This ensures the stability of the distance between the support rods 2 during bending and the overall stability of the round steel crossover bending forming device, guaranteeing the consistency of the round steel bending forming. Preferably, the fastener 6 can be a bolt or a threaded rod with a locking nut. In an exemplary example, the limiting rod 5 is provided with a groove 52 corresponding to the pressure rod 3. The groove 52 can limit the pressure rod 3 in the direction of rotation. The pressure rod 3 applies force toward the round steel, causing the round steel to bend and form. Through the limiting effect of the groove 52, the degree of bending of the round steel is controlled, ensuring the consistency of the round steel bending and forming.

[0025] In use, first, place the round steel jumper bending and forming device provided by this utility model on the platform or workbench. Then, insert the round steel into the slot 21 below the limiting piece 4. Hold the end of the pressure rod 3 away from the hinge shaft 12 and press the pressure rod 3 toward the round steel until the pressure rod 3 is blocked by the support slot 52 or the workbench surface, thus completing the production of the round steel jumper.

[0026] This utility model provides a round steel jumper bending and forming device. Through the hinged connection between the pressure rod and the base, and the parallel support rods on both sides of the pressure rod, the round steel is bent and deformed between three points: the contact point between the round steel and the pressure rod, and the contact points between the two ends of the round steel and the support rods. The rotation of the pressure rod around the hinge axis applies force to the round steel, allowing for one-time bending to produce the desired round steel jumper. The operation is simple, the forming consistency is high, and it is beneficial to improve bending efficiency and the quality of the round steel jumper. The sliding connection between the support rod and the base allows for adjustment of the distance between the two support rods, thereby obtaining bending angles with different arc lengths and bending radii to meet different bending and forming requirements of the round steel jumper. The setting of the limiting plate ensures that the two ends of the round steel remain horizontal during bending, enabling the rapid and efficient production of "Ω" shaped round steel jumpers. The setting of the limiting rod and the groove further ensures the consistency and stability of the round steel bending and forming.

[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
