Traditional cables can no longer meet the requirements of high-current transmission systems, and busbar trunking has emerged as a new type of power distribution conductor. Currently, the profiles of purchased single busbar trunking have straight ends (e.g., Figure 1 (Left end of the busbar trunking) Due to the complex application environment of busbar trunking, in order to facilitate the assembly of high-density busbar copper busbars, the vertical ribs on the inner side of many busbar trunkings must be bent when assembling high-density busbars (such as...). Figure 1 The right end of the middle busbar trunking makes the overall busbar trunking easier to assemble.

Detailed Implementation The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 2 As shown, a busbar trough 1 bending machine includes a material support frame 2 and a bending device. The bending device includes a base, the material support frame 2 is connected to the base, and the upper end of the base is provided with a pressing mechanism, a positioning mechanism and a bending mechanism. The non-powered material support frame 2 is adopted, and the upper end is equipped with a material support roller for easy loading and unloading.

[0016] The pressing mechanism is used to press and fix the busbar trough 1 to ensure the stability of the busbar trough 1 during the bending process.

[0017] The positioning mechanism includes a second positioning rod 308 and a liftable first positioning rod 701. The first positioning rod 701 positions the loading position of the busbar trough 1 and limits the bending angle of the vertical rib 101 of the busbar trough 1. The second positioning rod 308 limits the bending width of the vertical rib 101. The bending mechanism includes a bending cylinder 8 fixed to the base. A bending punch is connected to the piston rod of the bending cylinder 8. Auxiliary punches 501 are provided on both sides of the bending punch to push the vertical rib 101 to both sides. The bending punch and the auxiliary punches 501 push the vertical rib 101 outward to bend it. The bending and shaping of the vertical rib 101 is achieved with the help of the positioning mechanism.

[0018] The specific structure is as follows: like Figure 3 As shown, a side stop bar 301 is provided at the upper end of the base to position the busbar 1 side, that is, the busbar 1 is pushed into the bending device along the side stop bar 301. The pressing mechanism includes a pressing cylinder 6, and a pressing block 601 of the pressing busbar groove 1 is connected to the piston rod of the pressing cylinder 6.

[0019] The upper end of the base is provided with a lower base plate 403. The upper end of the lower base plate 403 is connected to an upper cover plate 303 through a support plate 302. The upper end of the upper cover plate 303 is equipped with a first bracket 304 and a pressing cylinder 6. The pressing block 601 is located below the upper cover plate 303. The first bracket 304 is provided with a lifting cylinder 7, which is connected to the first positioning rod 701.

[0020] like Figure 6 , Figure 8 As shown, there are two first positioning rods 701. The upper end of the first positioning rod 701 passes through the upper cover plate 303. The lower base plate 403 is provided with a clearance hole that cooperates with the first positioning rod 701. The upper ends of the two first positioning rods 701 are connected by a pull block 703. The pull block 703 is located above the upper cover plate 303. The piston rod of the lifting cylinder 7 is connected to the pull block 703. The lifting and lowering of the first positioning rod 701 is realized by the lifting cylinder 7.

[0021] During loading, the first positioning rod 701 drops down, and after the busbar trough 1 is pushed in, the first positioning rod 701 positions the end of the busbar trough 1. The side of the first positioning rod 701 facing the vertical rib 101 is a limiting inclined surface 702. When the vertical rib 101 is bent, the limiting inclined surface 702 can limit the bending angle of the vertical rib 101. During unloading, the first positioning rod 701 rises to the maximum height and disengages from the busbar trough 1, making it easy to remove the busbar trough 1 smoothly.

[0022] The second positioning rod 308 is fixed between the upper cover plate 303 and the lower base plate 403. When bending, the second positioning rod 308 can limit the maximum outward distance of the vertical rib 101, that is, limit the maximum spacing between the two vertical ribs 101.

[0023] The bending cylinder 8 is fixed to the base via the second bracket 305, such as Figure 7 As shown, the bending punch has forming inclined surfaces 804 on both sides that cooperate with the auxiliary punch 501, such as... Figure 4 As shown, both the upper cover plate 303 and the lower base plate 403 are provided with guide holes 306, such as... Figure 9 As shown, the auxiliary punch 501 is cylindrical, and the two ends of the auxiliary punch 501 are provided with guide shafts 502 that cooperate with the guide holes 306. The guide shafts 502 and the auxiliary punch 501 are integrally formed, that is, a stepped cylindrical punch with a hardened surface. The diameter of the auxiliary punch 501 is larger than the diameter of the guide shafts 502. The upper end of the upper cover plate 303 is fixed with a reset cylinder 5 connected to the guide shafts 502.

[0024] In the initial position, the two auxiliary punches 501 are located at the foremost end of the forming inclined surface 804, and the distance between the two auxiliary punches 501 is less than the distance between the two vertical ribs 101. When the bending punch moves forward, the auxiliary punches 501 tangentially rub against the forming inclined surface 804, causing the auxiliary punches 501 to move obliquely along the guide hole 306, completing the bending action of the busbar trough 1 box. With the help of the auxiliary punches 501, the forming resistance is greatly reduced by using rolling friction.

[0025] The reset cylinder 5 has an air pipe installed at its rear end. When bending, the reset solenoid valve closes and the air supply is cut off. The piston rod of the reset cylinder 5 retracts along with the auxiliary punch 501. After bending is completed, the reset solenoid valve opens, the cylinder is vented, and the piston rod extends to push the auxiliary punch 501 to its initial position to wait.

[0026] like Figure 5 As shown, the upper end of the base is provided with a guide block 307, and the bottom of the bending punch is provided with a guide groove 805 that cooperates with the guide block 307, so that the bending punch can only move forward and backward on the guide block 307, ensuring the accuracy of the bending angle.

[0027] Limiting blocks 802 are provided on both sides of the bending punch. Limiting bolts 803 are connected to the limiting blocks 802 and are in contact with the end of the support plate 302. The bending distance is controlled by the length of the limiting bolts 803 to ensure the bending size.

[0028] The upper part of the base is provided with a protective cover 4. The side wall of the protective cover 4 is provided with a feed port 402 and a side door 401. The side door 401 facilitates manual adjustment and maintenance of the equipment.

[0029] The dual pneumatic foot switch is located on one side of the base, and the control box is located inside the base. It is divided into two parts, pneumatic control and electric control, by a partition. This is the structure and will not be described in detail.

[0030] Busbar 1 (e.g.) Figure 1Push the workpiece into the equipment along the side stop bar 301 (left end). Step on the double pneumatic foot switch (working switch). The clamping cylinder first clamps the busbar 1. The solenoid valve of the bending cylinder 8 opens after a delay. The bending cylinder 8 drives the bending punch to move and bend the vertical rib 101. After a few seconds, the bending punch automatically returns to its original position. Step on the double pneumatic foot switch (reset switch). At this time, the reset cylinder 5 drives the auxiliary punch 501 to reset. At the same time, the lifting cylinder 7 runs, driving the first positioning rod 701 to rise to the stop position. The clamping cylinder opens through the time delay relay. The pressure block 601 moves upward to release the busbar 1. Finally, the workpiece is taken out, completing the bending of the busbar 1 box (e.g., Figure 1 (The right end) action.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
