Description

Technical Field

[0001] This utility model relates to the field of hand tool technology, and in particular to a portable manual bending machine for grounded flat iron. Background Technology

[0002] In the construction of grounding systems in industries such as power, construction, and communications, the precise bending of grounding flat iron is a core process to ensure the performance of the grounding system. Taking the construction of lightning protection grounding network for a super high-rise commercial complex as an example, the entire building needs to be laid with grounding flat iron that is several kilometers long. Through a large number of precise bends at 90° right angles and 135° corners, a three-dimensional ring grounding network is constructed. According to professional tests, if the bending angle deviation of the grounding flat iron exceeds 8°, the contact resistance of the electrical connection point will increase by 2-3 times, resulting in the grounding resistance exceeding the design standard by more than 30%. For example, a 300-meter landmark building under construction had an initial grounding resistance test value as high as 8Ω due to the excessive error in the bending angle of the grounding flat iron, which far exceeded the design requirement of 4Ω. The project was forced to be reworked and rectified, which directly caused a 15-day delay in the construction period and an additional material and labor cost of more than 200,000 yuan.

[0003] Currently, in most construction scenarios, operators of traditional manual grounding flat iron bending machines are only equipped with bending machines featuring movable angle plates, using bolt fastening or clip connections for fixation. However, in actual operation, due to the enormous lateral force generated when bending the grounding flat iron (the instantaneous stress when bending a 40×4mm flat iron can reach 500-800N), the angle plate is prone to loosening and displacement. When using this type of bending machine, the angle plate needs to be recalibrated on average every 30 bends, resulting in a bending angle error generally between 10° and 15°, which reduces the practicality and flexibility of the equipment. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a portable manual bending machine for grounding flat iron. This machine can solve the problem of angle control in most construction scenarios where operators are only equipped with bending machines with movable angle plates, which use bolt fastening or buckle connection for fixing. However, in actual operation, due to the huge lateral force generated when bending the grounding flat iron (the instantaneous stress can reach 500-800N when bending a 40×4mm flat iron), the angle plate is very easy to loosen and shift. When using this type of bending machine, the angle plate needs to be recalibrated on average every 30 bends, resulting in a bending angle error of generally between 10° and 15°, which reduces the practicality and flexibility of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable manual bending machine for grounded flat iron, comprising a base, a handle, a rotating disk and two fixing blocks, wherein an angle component is provided on the base;

[0006] The angle assembly includes a first dial, a second dial, and an H-block. The upper surface of the base has a dial mounting groove, and the inside of the dial mounting groove has four first fixing bolt grooves. The upper surface of the H-block is threaded with two second fixing bolts. A T-block groove is provided on one side of the outer wall of the first dial.

[0007] The second dial has a T-shaped block groove on one side of its outer wall. Both T-shaped block grooves have a second fixing bolt groove inside. The first and second dials are slidably connected inside the dial mounting groove. The outer walls of the first and second dials away from the H-shaped block are threaded with two first fixing bolts.

[0008] Preferably, both the first and second dials are arc-shaped, and the T-shaped slots on the first and second dials cooperate with each other.

[0009] The two outer walls of the H-shaped block are slidably connected to the T-shaped block grooves on the first and second dials, respectively.

[0010] Preferably, the ends of the two second fixing bolts near the second fixing bolt slots are both threaded into the interior of the T-shaped block slot and respectively connected to the internal threads of the corresponding second fixing bolt slots;

[0011] Among them, the ends of the four first fixing bolts near the first fixing bolt slots are all threaded into the interior of the dial mounting slot and respectively connected to the internal threads of the corresponding first fixing bolt slots.

[0012] Preferably, a support shaft is fixedly connected to the upper surface of the base, and two fixing blocks are respectively fixedly installed on the upper surface of the base and the outer wall of the rotating disk;

[0013] The rotating disk is rotatably connected to the upper surface of the base, and the support shaft is located inside the groove in the middle of the rotating disk.

[0014] Preferably, the handle is fixedly installed on the outer wall of one side of the fixing block on the rotating disk, and clamping blocks are slidably connected inside the two fixing blocks on the side near the support shaft;

[0015] Both clamping blocks are T-shaped, and the outer walls of both fixing blocks are threaded with rotating threaded rods.

[0016] Preferably, the grooves on the two clamping blocks are slidably connected to the outer wall of the fixing rod in the limiting assembly installed on the corresponding fixing block, and the limiting assembly on the two fixing blocks is composed of a fixing rod and a nut;

[0017] The two rotating threaded rods have their ends near the clamping block threaded into the interior of the fixed block and are rotatably connected to the outer wall of one side of the corresponding clamping block.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This portable manual bending machine for grounding flat iron uses an angle assembly to place the first and second dials into the dial mounting slots on the base. Then, the two sides of the H-block are inserted into the T-block slots of the first and second dials respectively. The second fixing bolt on the H-block is tightened, extending one end of its thread into the second fixing bolt slot within the T-block slot to fix the position of the H-block. Finally, the first fixing bolts on the first and second dials are tightened to fix them in the dial mounting slots. This allows workers to refer to the angles of the first and second dials when bending the flat iron, effectively improving the accuracy of bending and preventing the angle plates from easily loosening or shifting.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a portable manual bending machine for grounded flat iron, including a base 1, a handle 5, a rotating disk 12 and two fixing blocks 2;

[0031] An angle component is provided on the base 1;

[0032] The angle assembly includes a first dial 7, a second dial 11, and an H-block 14. The upper surface of the base 1 has a dial mounting groove 8, and the interior of the dial mounting groove 8 has four first fixing bolt slots 16. Both the first dial 7 and the second dial 11 are arc-shaped. The upper surface of the H-block 14 is threaded with two second fixing bolts 10. One side of the outer wall of the first dial 7 has a T-shaped block groove 9, and one side of the outer wall of the second dial 11 has the same T-shaped block groove 9. The T-shaped block grooves 9 on the first dial 7 and the second dial 11 cooperate with each other. The two outer walls of the H-block 14 respectively engage with the corresponding T-shaped block grooves 9 on the first dial 7 and the second dial 11. The two T-shaped block slots 9 are slidably connected. The interior of each T-shaped block slot 9 is provided with a second fixing bolt slot 15. The ends of the two second fixing bolts 10 near the second fixing bolt slots 15 are threaded into the interior of the T-shaped block slot 9 and respectively connected to the internal threads of the corresponding second fixing bolt slots 15. The first dial 7 and the second dial 11 are slidably connected inside the dial mounting slot 8. The outer walls of the ends of the first dial 7 and the second dial 11 away from the H-shaped block 14 are threaded with two first fixing bolts 6. The ends of the four first fixing bolts 6 near the first fixing bolt slots 16 are threaded into the interior of the dial mounting slot 8 and respectively connected to the internal threads of the corresponding first fixing bolt slots 16.

[0033] The base 1 has a support shaft 13 fixedly connected to its upper surface. Two fixed blocks 2 are fixedly installed on the upper surface of the base 1 and the outer wall of the rotating disk 12, respectively. The rotating disk 12 is rotatably connected to the upper surface of the base 1. The support shaft 13 is located inside the groove in the middle of the rotating disk 12. The handle 5 is fixedly installed on the outer wall of one side of the fixed block 2 on the rotating disk 12. The two fixed blocks 2 are slidably connected to the clamping blocks 4 on the side near the support shaft 13. The two clamping blocks 4 are both "T" shaped. The outer walls of the two fixed blocks 2 are threadedly connected to rotating threaded rods 3. The grooves on the two clamping blocks 4 are slidably connected to the outer walls of the fixing rods in the limiting components installed on the corresponding fixed blocks 2. The limiting components on the two fixed blocks 2 are both composed of fixing rods and nuts. The ends of the two rotating threaded rods 3 near the clamping blocks 4 are threaded into the interior of the fixed blocks 2 and are rotatably connected to the outer walls of one side of the corresponding clamping blocks 4.

[0034] Furthermore, when using this device, firstly, the first dial 7 and the second dial 11 are placed into the dial mounting slot 8 on the base 1. Then, the two sides of the H-shaped block 14 are inserted into the T-shaped block slots 9 of the first dial 7 and the second dial 11, respectively. The second fixing bolt 10 on the H-shaped block 14 is tightened so that one end of its thread extends into the second fixing bolt slot 15 in the T-shaped block slot 9, fixing the position of the H-shaped block 14, thereby fixing the relative angle of the first dial 7 and the second dial 11. Then, the first fixing bolt 6 on the first dial 7 and the second dial 11 is tightened to fix the first dial 7 and the second dial 11 in the dial mounting slot 8. Then, the grounding flat iron is placed between the two fixing blocks 2, and the rotating threaded rod 3 on the two fixing blocks 2 is rotated respectively. The rotating threaded rod 3 pushes the clamping block 4 to slide in the fixing block 2. The clamping block 4 gradually approaches the grounding flat iron and clamps it. Due to the upper limit assembly between the clamping block 4 and the fixing block 2, The fixed rod in the middle ensures the stability of the sliding of the clamping block 4, thus achieving a firm clamping of the grounding flat iron. Then, the operator holds the handle 5 and rotates it forcefully. The handle 5 drives the rotating disk 12 to rotate around the support shaft 13. When the rotating disk 12 rotates, it drives the fixed block 2 connected to it to rotate. Since the grounding flat iron is clamped by the two fixed blocks 2, under the drive of the rotating disk 12, the grounding flat iron is bent according to the angle set by the first scale 7 and the second scale 11. During the bending process, the first scale 7 and the second scale 11 of the angle assembly remain fixed to ensure the accuracy of the bending angle. After the bending operation is completed, the threaded rod 3 is rotated in the opposite direction to release the clamping block 4 and take out the bent grounding flat iron. If it is necessary to adjust the bending angle, the first fixing bolt 6 and the second fixing bolt 10 can be loosened, and the positions of the first scale 7 and the second scale 11 can be readjusted. After the angle adjustment is completed, the bolts are tightened again to perform the next bending operation.

[0035] The first dial 7 and the second dial 11 are placed into the dial mounting slot 8 on the base 1 using the angle assembly. Then, the two sides of the H-block 14 are inserted into the T-block slots 9 of the first dial 7 and the second dial 11, respectively. The second fixing bolt 10 on the H-block 14 is tightened so that one end of its thread extends into the second fixing bolt slot 15 in the T-block slot 9, fixing the position of the H-block 14. Then, the first fixing bolt 6 on the first dial 7 and the second dial 11 is tightened to fix the first dial 7 and the second dial 11 in the dial mounting slot 8. In this way, when the operator bends the flat iron, he can refer to the angle of the first dial 7 and the second dial 11 for bending, which effectively improves the accuracy of bending the flat iron and avoids the angle plate from easily loosening and shifting.

[0036] Structural Description: Base 1: Base 1 is the basic support component of the entire bending machine, providing an installation foundation and operating platform for other structures. Its upper surface has a dial mounting groove 8 for mounting the first dial 7 and the second dial 11. The dial mounting groove 8 also has four first fixing bolt slots 16. Through the cooperation of the first fixing bolts 6 with the first fixing bolt slots 16, the first dial 7 and the second dial 11 can be fixed within the dial mounting groove 8. In addition, a support shaft 13 is fixedly connected to the upper surface of base 1 to support the rotating disk 12, allowing the rotating disk 12 to rotate around it. Simultaneously, a fixing block 2 is also fixedly installed on the upper surface of base 1, providing an installation position for components such as the clamping block 4 and the rotating threaded rod 3.

[0037] First dial 7 and second dial 11: Both are arc-shaped, with a T-shaped block groove 9 on one side of the outer wall. The two T-shaped block grooves 9 cooperate with each other. The first dial 7 and the second dial 11 can slide in the dial mounting groove 8. By changing their relative positions, the bending angle can be adjusted. Two first fixing bolts 6 are threaded to the outer wall of the end away from the H-shaped block 14, which can fix them in the dial mounting groove 8. At the same time, a second fixing bolt groove 15 is opened inside the T-shaped block groove 9, which cooperates with the second fixing bolt 10 on the H-shaped block 14 to fix the H-shaped block 14, thereby fixing the relative positions of the first dial 7 and the second dial 11.

[0038] H-block 14: The upper surface is threaded with two second fixing bolts 10, and the outer walls on both sides are slidably connected to the T-block grooves 9 on the first scale 7 and the second scale 11 respectively. By tightening or loosening the second fixing bolts 10, the sliding and fixing of H-block 14 in the T-block groove 9 can be controlled, thereby adjusting the relative angle between the first scale 7 and the second scale 11.

[0039] There are two fixed blocks 2, which are fixedly installed on the upper surface of the base 1 and the outer wall of the rotating disk 12 respectively. Each fixed block 2 has a rotating threaded rod 3 threadedly connected to its outer wall, and a T-shaped clamping block 4 is slidably connected inside. The groove on the clamping block 4 is slidably connected to the outer wall of the fixed rod in the upper limit assembly of the fixed block 2. The end of the rotating threaded rod 3 near the clamping block 4 extends into the interior of the fixed block 2 and is rotatably connected to the outer wall of one side of the clamping block 4. By rotating the rotating threaded rod 3, the clamping block 4 can be pushed to slide inside the fixed block 2, thereby clamping and releasing the grounding flat iron.

[0040] The rotating disk 12 is rotatably connected to the upper surface of the base 1, and a slot is opened in the middle to fit on the support shaft 13. It can rotate around the support shaft 13. The handle 5 is fixedly installed on the outer wall of one side of the fixed block 2 on the rotating disk 12. The operator rotates the handle 5 to drive the rotating disk 12 to rotate around the support shaft 13, thereby realizing the bending operation of the ground flat iron clamped between the two fixed blocks 2.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
