[0002] At present, a large number of galvanized flat steel exposed construction processes will occur in the construction of grounding systems for conventional buildings. In actual construction, a large number of galvanized flat steels will require corresponding elbows at corners. The galvanized flat steels sold on the market (such as 40*4 models) do not have matching elbows. The current way to solve this problem is on-site processing. Due to the lack of supporting tools, the processing quality is seriously unqualified or some units directly use butt welding to weld the flat steel into right angles at the corners, which cannot meet the connection multiples required by the specifications, seriously affecting the construction quality of the lightning protection system and increasing the safety hazards of the overall use of the building.

[0007] Optionally, the base is a prism structure, and the bottom surface area of ​​the base is larger than the top surface area.

[0008] The flat steel cold bending device of the utility model fixes the flat steel to be processed on a horizontal slideway, and uses a fiber piece to fix the flat steel on a horizontal rod of an operating wrench; since the oblique rod of the operating wrench is connected to the connecting shaft inside the connecting tube, and the connecting shaft is rotatably connected to the fixed discs on both sides, the flat steel can be bent to a required angle by rotating the operating wrench, thereby obtaining a flat steel elbow that meets the requirements, greatly improving the quality and speed of on-site construction of the flat steel, reducing the safety hazards of the lightning protection grounding system, and well ensuring the quality of the project.

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] See also Figure 1 and Figure 2The utility model provides a flat steel cold bending device, including a base 1, a horizontal slide 9 is arranged at the top of the base 1, two fixed discs 5 are fixedly installed on both sides of the horizontal slide 9, and the two fixed discs 5 are fixedly connected together by a connecting tube 6, a positioning groove 10 is formed between the two fixed discs 5, the horizontal slide 9 and the connecting tube 6, so that the flat steel 11 to be processed is placed inside the positioning groove 10, a connecting shaft 3 is arranged inside the connecting tube 6, both ends of the connecting shaft 3 pass through the two ends of the connecting tube 6 and are rotatably connected to the fixed discs 5 on both sides respectively, an operating wrench 2 is connected inside the connecting tube 6, and the operating wrench 2 includes an inclined rod 21 and a horizontal rod 22, one end of the inclined rod 21 is inserted into the connecting tube 6 and connected to the connecting shaft 3, and the other end is connected to one end of the horizontal rod 22, the horizontal rod 22 is parallel to the plane where the horizontal slide 9 is located, and a limiting member 12 is installed on the horizontal rod 22, so as to fix the flat steel 11 to be processed through the limiting member 12.

[0029] In this embodiment, when the flat steel needs to be cold bent, the flat steel 11 to be processed is fixedly placed inside the positioning groove 10 on the horizontal slide 9 above the base 1, and then the flat steel 11 to be processed only needs to be fixed to the bottom of the horizontal rod 22 below the operating wrench 2 through the limiter 12. After fixation, by lifting the operating wrench 2 upward, the inclined rod 21 of the operating wrench 2 rotates through the connecting shaft 3, so that the flat steel 11 to be processed can be driven to be bent to the required angle. After the bending process is completed, the limiter 12 is released to remove the bent flat steel 11 from the horizontal slide 9. The whole operation process is simple and convenient, which effectively improves the processing efficiency of the flat steel during on-site bending.

[0030] In some embodiments, an adjustment block 8 is movably provided above the horizontal slide 9, and the outer side of the adjustment block 8 is connected to the fixed disc 5 on the same side by a connecting bolt 13, so that the position of the adjustment block 8 can be adjusted by the connecting bolt 13. In order to ensure that the flat steel 11 to be processed placed on the horizontal slide 9 is not easy to loosen, a movable adjustment block 8 is provided, and the position of the adjustment block 8 is adjusted by the connecting bolt 13, so that the position of the adjustment block 8 is adjusted, so that the gap between the adjustment block 8 and the fixed disc 5 without the connecting bolt 13 can adapt to the size of the flat steel 11 to be processed, so as to ensure that the flat steel 11 can remain fixed, thereby improving the stability and safety of the subsequent bending operation of the flat steel 11.
