Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical tools, in particular to a tool for making a grounding device bridging round steel. Background Art
[0002] In the lightning protection grounding system, the grounding device often uses the building foundation steel bars as the grounding body, welds the upper and lower main bars of the foundation bottom plate into a ring along the outer circle of the building, and welds the upper and lower main bars of the foundation beam on the main axis and the structural floor into a mesh grounding body. The roof lightning protection belt often uses φ12 hot-dip galvanized round steel as a lightning protection net along the parapet and roof, and uses the steel bars in the building structure column as the lightning protection down conductor. Each down conductor is welded to the lightning arrester, and the lower part is welded to the lightning protection grounding body to form an electrical path.
[0003] The traditional grounding device jumper wire uses Φ12 galvanized round steel, which is cut into fixed lengths and manually bent by workers, and adjusted by hammering. This results in a long production cycle, and the quality cannot be guaranteed. It is time-consuming and labor-intensive, inefficient, and increases personnel costs, affecting the construction progress. During the construction of roof lightning protection belts, the connection of the lightning protection net at the deformation joint of the building is often made of arched and bent round steel for connection. However, due to the limitations of construction site conditions, when quickly processing the connecting round steel of the lightning protection belt, workers usually use pipe benders to process the arched and bent connecting round steel based on their work experience, resulting in no uniform specifications for the size of the processed finished product, poor appearance, and low processing efficiency. At the same time, due to the non-uniform size of the connecting round steel, some formed connecting round steel cannot be used, resulting in waste, thereby increasing material costs. Utility Model Content
[0004] In order to solve the above defects in the prior art, the utility model discloses a tool for making a grounding device bridging round steel, which is realized by adopting the following technical scheme.
[0005] A tool for making round steel with a grounding device bridge, comprising a frame, a shaft sleeve, a rotating shaft, a pressure rod, and a support block. The rotating shaft rotates in two shaft sleeves on the frame, the rotating shaft is provided with a pressure rod perpendicular to the rotating shaft, the frame is provided with two support blocks, the two support blocks are symmetrically distributed on both sides of the pressure rod, the support blocks are provided with a slot matching the round steel, the pressure rod is sleeved with a cylindrical upper die, a lower die is provided between the two support blocks, the lower die is provided with a semicircular groove corresponding to the upper die, and the frame is provided with a shearing component for cutting the round steel.
[0006] Furthermore, the pressure rod is provided with a limiting ring for axially limiting the upper die, and the pressure rod is threadedly connected with a nut for fixing the upper die.
[0007] Furthermore, the shearing assembly includes a crank, a pin, a scissors handle, a scissors head, a fixed blade head, a return spring, and a limit block. The crank is arranged on a rotating shaft, the pin is arranged on the crank and cooperates with the scissors handle hinged on the frame, the scissors handle is provided with a scissors head, the scissors head cooperates with the fixed blade head on the frame, and a return spring is connected between the scissors handle and the frame to open the scissors head.
[0008] Furthermore, a limit block cooperating with the non-blade side of the scissors head is arranged on the frame, and the limit block is used to limit the opening range of the scissors head.
[0009] Furthermore, a top plate for axially positioning the round steel is arranged on the frame, and the top plate and the shearing assembly are respectively arranged on the left and right sides of the two supporting blocks.
[0010] Furthermore, the distance between the scissor head and the corresponding side support block is equal to the distance between the top plate and the corresponding side support block, ensuring that the middle of the section cut by the shearing assembly is exactly located between the two support blocks, so that the upper mold and the lower mold form a bridging arc in the middle of the round steel section, thereby ensuring that the formed bridging round steel has uniform specifications and dimensions.
[0011] Furthermore, the lower mold has blocks on both sides, and the frame has slots corresponding to the blocks.
[0012] The beneficial effects of the utility model are as follows:
[0013] The utility model uses a shearing assembly driven by a pressure rod to cut a fixed length of round steel inserted into the upper slots of the two support blocks. The middle part of the cut fixed length round steel is pressed by the upper die and the lower die to form a bridging arc with a fixed curvature and a fixed arc length under the continued downward pressure of the pressure rod, so that the final formed bridging round steel has a uniform size specification, shortens the production cycle of the bridging round steel, improves the production efficiency of the bridging round steel, ensures the final forming quality of the bridging round steel, reduces personnel costs, speeds up the construction progress of the grounding device installation, and at the same time, avoids the waste of materials and labor caused by a part of the formed bridging round steel being unable to be used due to the random size of the manually bent bridging round steel. In addition, the bridging round steel processed by the utility model is more beautiful after installation because it has a uniform size specification. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 , 2As shown in 4, a grounding device bridge round steel production tool includes a frame, a sleeve, a rotating shaft, a pressure rod, and a support block. The rotating shaft rotates in two sleeves on the frame, and the rotating shaft is provided with a pressure rod perpendicular to it. The frame is provided with two support blocks, and the two support blocks are symmetrically distributed on both sides of the pressure rod. The support block has a groove that matches the round steel, and the pressure rod is sleeved with a cylindrical upper mold. A lower mold is arranged between the two support blocks, and the lower mold has a semicircular groove corresponding to the upper mold. The frame is provided with a shearing component for cutting the round steel.
[0024] like Figure 2 As shown, the pressure rod is provided with a limiting ring for axially limiting the upper die, and the pressure rod is threadedly connected with a nut for fixing the upper die.
[0025] like Figure 3 As shown, the shearing assembly includes a crank, a pin, a scissors handle, a scissors head, a fixed blade head, a return spring, and a limit block. The crank is arranged on a rotating shaft, the pin is arranged on the crank and cooperates with the scissors handle hinged on the frame, the scissors handle is provided with a scissors head, the scissors head cooperates with the fixed blade head on the frame, and a return spring is connected between the scissors handle and the frame to open the scissors head.
[0026] like Figure 3 As shown, the frame is provided with a limit block cooperating with the non-blade side of the scissors head, and the limit block is used to limit the opening range of the scissors head.
[0027] like Figure 1 , 2 As shown, the frame is provided with a top plate for axially positioning the round steel, and the top plate and the shearing assembly are respectively arranged on the left and right sides of the two supporting blocks.
[0028] like Figure 3 As shown, the distance between the scissor head and the corresponding side support block is equal to the distance between the top plate and the corresponding side support block, ensuring that the middle of the section cut by the shearing assembly is exactly located between the two support blocks, so that the upper mold and the lower mold form a bridging arc in the middle of the round steel section, thereby ensuring that the formed bridging round steel has uniform specifications and dimensions.
[0029] like Figure 3 , 4 As shown, there are clamping blocks on both sides of the lower mold, and there are slots on the frame corresponding to the clamping blocks.
[0030] The operating principle or process of the utility model is as follows:
[0031] In the initial state, the upper die on the pressure rod is located in the groove of the lower die, the pin on the crank interacts with the scissors handle, the scissors head and the fixed cutter head are in a closed state, the reset spring is in a stretched state, and the scissors head is out of the limit block.
[0032] First, replace the upper die and lower die according to the size of the crossover arc to be bent on the round steel, pull up the pressure rod to make the upper die out of the groove of the lower die, unscrew the nut from the pressure rod, remove the upper die on the pressure rod, and install the new upper die on the pressure rod, and fix the new upper die with the nut. Remove the lower die on the frame and insert the new lower die into the slot to complete the replacement of the upper die and lower die.
[0033] After the pressure rod swings up, the pin is separated from the scissors handle, and the scissors handle drives the scissors head to open under the action of the reset spring. The scissors head contacts the limit block, and the limit block limits the opening range of the scissors head so that the round steel between the scissors head and the fixed blade head can pass through after the scissors head is opened.
[0034] Then, insert the round steel into the upper slots of the two support blocks in sequence from between the scissor head and the fixed knife head and finally abut against the top plate. Press the pressure rod downward so that the pressure rod swings down around the rotating shaft, and the pressure rod drives the upper mold to swing into the semicircular groove of the lower mold.
[0035] During the swinging of the pressure rod, the rotating shaft drives the pin to interact with the scissor handle through the crank. The pin presses down the scissor handle so that the scissor handle swings down around the hinge point. The reset spring is further stretched to store energy. The scissor handle drives the scissor head to close toward the fixed blade head and finally cuts the round steel. The upper die interacts with the round steel only after the scissor head and the fixed blade head have completed cutting the round steel. Since the distance between the scissor head and the corresponding side support block is equal to the distance between the top plate and the corresponding side support block, the middle of the section cut by the shearing assembly is exactly between the two support blocks. During the process of the upper die pressing and bending the middle of the round steel section into the semicircular groove of the lower die, the two ends of the round steel section shrink horizontally toward the corresponding side support blocks at the same time, so that the middle of the round steel section is formed into a bridging arc under the cooperation of the upper die and the lower die, thereby ensuring that the formed bridging round steel has uniform specifications and dimensions.
[0036] After the bridging arc in the middle of the round steel section is formed, the pressure rod is lifted to allow the upper die to separate from the semicircular groove of the lower die and the bridging arc of the round steel. In the process of the upper die separating from the upper semicircular groove of the lower die, the push pin gradually separates from the scissors handle, and the scissors handle drives the scissors head to open and separate from the fixed cutter head under the reset action of the reset spring.
[0037] After the pressure rod is fully lifted, the formed bridging round steel is taken out from the two support blocks. Subsequently, the round steel on the fixed blade head side is inserted into the slots on the two support blocks in turn through between the scissor head and the fixed blade head and abutted against the top plate.
[0038] Then, the round steel is sheared again and a bridging arc is formed in the middle of the round steel section according to the above process.
