[0032] Please refer to the following: Figure 1 and Figure 2 The bending assembly 30 includes a fixed base 31, a first roll 32, a second roll 33, and a pressure roll 34.

Further, the bending power element 37 is mounted on the top of the support portion 312.
[0034] like Figure 1As shown, the limiting component 40 includes a baffle 41 and two horizontal plates 42. The baffle 41 is slidably mounted on the frame 10 and is used to abut one end of the sheet metal. The two horizontal plates 42 are slidably mounted on both sides of the support frame 21, respectively, and cooperate to abut the two sides of the sheet metal. By sliding the two horizontal plates 42 in opposite directions synchronously, the sheet metal is automatically centered. Optionally, one end of the horizontal plate 42 extends above the second roller 33 to ensure that during bending, the two horizontal plates 42 abut the two sides of the sheet metal respectively, preventing displacement. In one embodiment, the limiting component 40 further includes a base plate 43 and a telescopic power element 44, with two base plates 43 and two telescopic power elements 44, which correspond one-to-one; the two base plates 43 are respectively installed on both sides of the support frame 21, and the telescopic power element 44 is installed on the base plate 43, and the telescopic power element 44 is used to drive the horizontal plate 42 to slide; optionally, the base plate 43 is provided with a corresponding through hole 231.
[0035] In one embodiment, the limiting assembly 40 further includes a plurality of guide wheels 45, each of which is rotatably connected to the horizontal plate 42; the guide wheels 45 are used to abut one side of the plate; the guide wheels 45 are arranged along the length direction of the horizontal plate 42; optionally, one of the guide wheels 45 is located above the second roller 33. The limiting assembly 40 also includes a guide bar 46 and an adjusting power element 47, both of which are mounted on the frame 10, and the baffle 41 is slidably disposed on the guide bar 46; the adjusting power element 47 is used to drive the baffle 41 to slide, thereby adjusting the position of the baffle 41.
[0036] Please check again. Figure 1 The limiting component 40 further includes a position sensor 48 and a displacement sensor 49. The position sensor 48 is mounted on the baffle 41 and is used to detect the position of the sheet material. The displacement sensor 49 is mounted on one side of the fixed base 31 and is used to detect the position of the baffle 41. Optionally, one end of the displacement sensor 49 is positioned corresponding to the central axis of the pressure roller 34. Further, the position sensor 48 is a contact switch, and the displacement sensor 49 is a laser displacement sensor, which is existing technology. Even further, the central axis of the pressure roller 34 is coaxially aligned with the bending point of the sheet material (the bending point is the lowest point of the sheet material during bending).
[0037] The sheet metal cold bending forming device 100 also includes a controller (not shown). The lateral movement force element 28, lifting power element 29, bending power element 37, telescopic power element 44, adjusting power element 47, position sensor 48, and displacement sensor 49 are all connected to the controller for signal transmission, enabling automated control—this is existing technology. When adjusting the position, the controller controls the operation of the adjusting power element 47 based on the distance between the bending point and the end of the sheet metal near the baffle 41. The adjusting power element 47 drives the baffle 41 to slide until the distance between the bending point and the end of the sheet metal near the baffle 41 is equal to the distance between the displacement sensor 49 and the baffle 41.
[0038] In use, adjust the position of the baffle 41 according to the distance between the bending point and the end of the sheet material closest to the baffle 41. Then, place the sheet material on the conveyor wheel 22. The telescopic power element 44 drives the horizontal plate 42 to move towards the center of the conveyor wheel 22. With the synchronous movement of the two horizontal plates 42, the sheet material is automatically centered. At this time, the guide wheel 45 abuts against the side of the sheet material. Then, the lifting power element 29 drives the lifting plate 25 to descend, thereby driving the push plate 26 to descend to the preset height. The lateral movement power element 28 then drives the slide plate 24 to move towards the discharge port 233, thereby causing the push plate 26 to abut against one end of the sheet material. The push plate 26 moves with the slide plate 24 and pushes the plate towards the baffle 41 until one end of the plate triggers the position sensor 48. At this time, one end of the plate abuts against the baffle 41, and the lateral movement force element 28 stops operating. At this time, the baffle 41 and the push plate 26 abut against the two ends of the plate respectively, and the guide wheels 45 on the two horizontal plates 42 abut against the two sides of the plate respectively. Finally, the bending power element 37 drives the mounting base 35 to descend, thereby driving the pressure roller 34 to descend until the plate is formed into the preset shape. After bending, the bending power element 37 rises, and the finished product after bending is manually removed.
[0039] The sheet metal cold bending forming device 100 of this utility model uses two horizontal plates 42 to abut against the two sides of the sheet metal, and a baffle 41 and a push plate 26 to abut against the two ends of the sheet metal respectively, thereby limiting the position of the sheet metal and preventing the sheet metal from shifting during bending.
[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
