[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] A copper busbar bending device comprises a processing table 1 and a copper busbar 2 to be bent. The copper busbar 2 is arranged above the processing table 1. Two positioning mechanisms are provided on the processing table 1. The two positioning mechanisms are respectively arranged at both ends of the copper busbar 2 for positioning the copper busbar 2.

[0025] The positioning mechanism includes a groove 3, two guide shafts 4 are fixedly connected in the groove 3, a movable splint 5 is slidably connected to the guide shaft 4, and an inclined guide plate 6 is fixedly connected to the top of the movable splint 5. The guide plate 6 is used to provide a guide for the downward movement of the copper bus 2. A reset spring 7 is fixedly connected to one side of the inner wall of the groove 3, and one end of the reset spring 7 is fixedly connected to the movable splint 5.

[0026] like Figure 1 The top of the processing table 1 is tilted, and there is a through hole on the copper busbar 2 to be bent. The through hole and the bending position on the copper busbar 2 are not at the same place. The guide shaft 4 and the return spring 7 are both located in the groove 3. The guide plate 6 is tilted away from the copper busbar 2, and the return spring 7 applies a thrust to the movable splint 5 toward the copper busbar 2.

[0027] The groove 3 is formed on the top of the processing table 1 , and the movable clamping plates 5 are vertically arranged. The two movable clamping plates 5 are respectively in contact with the two ends of the copper busbar 2 .

[0028] A first bending part 8 and a second bending part 9 are respectively provided on both sides of the copper busbar 2. A positioning recess 10 is fixedly connected to the top of the processing table 1. One side of the second bending part 9 is located in the recess of the positioning recess 10. Fixing holes 101 are opened at the four corners of the processing table 1.

[0029] like Figure 1 and Figure 2 The second bending part 9 is positioned by the positioning recess 10 so that the second bending part 9 will not be displaced when it is pressed.

[0030] A clamping convex plate 11 is fixedly connected to the side of the second bending member 9 away from the copper busbar 2 , and a clamping groove for use with the clamping convex plate 11 is formed on one side of the positioning recess 10 .

[0031] like Figure 1 and Figure 2 The clamping protrusion 11 and the clamping groove on the positioning recess 10 are clamped together to complete the installation of the second bending part 9. When replacing the second bending part 9, it is only necessary to pull the second bending part 9 away from the clamping protrusion 11 to separate the clamping protrusion 11 and the positioning recess 10.

[0032] A hydraulic telescopic rod 12 is fixedly connected to the top of the processing table 1, and a concave is provided on the side of the first bending part 8 away from the copper bus 2. The telescopic end of the hydraulic telescopic rod 12 is fixedly connected to a connecting block 13, which is located in the concave part of the first bending part 8.

[0033] like Figure 1 The connecting block 13 can be just stuck in the concave part of the first bending part 8, and the hydraulic telescopic rod 12 drives the connecting block 13 and the first bending part 8 to move together.

[0034] A locking screw 14 is provided on the first bending part 8, one end of the locking screw 14 passes through the first bending part 8 and the connecting block 13 in sequence and extends to the outside of the first bending part 8, both ends of the locking screw 14 are threadedly connected to a locking nut 15, and the top of the first bending part 8 is fixedly connected to a top limiting protrusion 16.

[0035] like Figure 1 and Figure 3 There are openings on the first bending part 8 and the connecting block 13, and the openings of the first bending part 8 and the connecting block 13 are aligned together, so that the locking screw 14 can pass through the first bending part 8 and the connecting block 13. At the same time, two locking nuts 15 are at both ends of the locking screw 14, locking the first bending part 8 and the connecting block 13 together. Conversely, the locking nuts 15 can be removed and the locking screw 14 can be pulled out. At this time, the first bending part 8 and the connecting block 13 can be separated and replaced with a different first bending part 8.

[0036] When the first bending piece 8 and the second bending piece 9 are close to bend the copper busbar 2 , the top limiting protrusion 16 moves to above the copper busbar 2 , so as to limit the copper busbar 2 from above.

[0037] The working principle of the copper busbar bending equipment provided by the utility model is as follows:

[0038] When the copper bar 2 needs to be bent, the copper bar 2 is moved down from between the two positioning mechanisms to the processing table 1. The copper bar 2 will squeeze the inclined surfaces of the guide plates 6 at both ends, so that the two guide plates 6 and the movable clamping plate 5 move away from each other without hindering the downward movement of the copper bar 2. When the copper bar 2 moves down between the two movable clamping plates 5, under the action of the reset spring 7, the movable clamping plate 5 positions the copper bar 2 on the processing table 1;

[0039] Then the hydraulic telescopic rod 12 extends to push the first bending part 8, and the first bending part 8 cooperates with the second bending part 9 to squeeze the copper busbar 2 from both sides to bend the copper busbar 2. When the copper busbar 2 bends, its two ends move and can squeeze the movable splint 5. The movable splint 5 moves away from the copper busbar 2 and will not hinder the bending of the copper busbar 2.

[0040] Compared with the related art, the copper busbar bending equipment provided by the present invention has the following beneficial effects:

[0041] The utility model uses the two movable splints 5 to squeeze and position the copper bar 2 from both sides under the action of the reset spring 7, so that each time the copper bar 2 is placed, it can be quickly positioned in the same area between the first bending part 8 and the second bending part 9, avoiding errors in the position of the copper bar 2 when the copper bar 2 is manually placed and bent, thereby improving the bending accuracy of the copper bar 2. At the same time, under the action of the reset spring 7, when the two ends of the copper bar 2 are bent, they can squeeze the movable splints 5 accordingly, so that the movable splints 5 will not hinder the bending of the copper bar 2.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
