[0024] Example 1

[0025] See also Figures 1 to 5 The utility model provides an embodiment: a bending device for high-voltage busbar production, comprising a workbench 1, on which are respectively mounted a static extrusion block 3 for bending a high-voltage busbar, a forming mechanism 5, and a driving mechanism 6 for driving the forming mechanism 5 to move linearly, the forming mechanism 5 comprising a dynamic extrusion block 51 aligned with the static extrusion block 3, the end of the static extrusion block 3 is provided with a bending portion for extruding the high-voltage busbar, a side of the dynamic extrusion block 51 is provided with a clearance groove 52, the two sides of the clearance groove 52 are oblique sides, and the clearance groove 5 The inner wall of the static extrusion block 2 is parallel to the hypotenuse of the bent portion on the static extrusion block 3. The inner wall of the give way groove 52 is provided with two symmetrically arranged mounting grooves 55. The inner wall of the mounting groove 55 is an arc surface. The two mounting grooves 55 are rotatably installed inside the two mounting grooves 55 for extruding the high-voltage busbar. The resistance block 53 is semi-cylindrical, and one side of the resistance block 53 is set as a plane. The resistance block 53 includes a rotating block 531. A groove 532 is provided on one side of the rotating block 531. A plurality of rollers 533 are rotatably installed inside the groove 532, and the outer wall of the roller 533 exceeds the groove 532.

[0026] A slider 534 is connected to the arc surface of the rotating block 531. The cross section of the slider 534 is trapezoidal. A slide groove 56 is opened on the inner wall of the installation groove 55. The slider 534 is slidably installed inside the slide groove 56 to ensure the stability of the rotating block 531 during rotation.

[0027] A backing plate 2 is installed on the workbench 1, a static extrusion block 3 is installed on the backing plate 2, and a positioning mechanism 4 for limiting one end of the high-voltage busbar is installed on the backing plate 2, and the positioning mechanism 4 is used to resist and position the high-voltage busbar.

[0028] The positioning mechanism 4 includes a fixing plate 41, a cylinder 42 is installed on one side of the fixing plate 41, and one end of the piston rod of the cylinder 42 is connected to an L-shaped limit plate 43 through a mounting seat. The limit plate 43 is driven by the cylinder 42 to move to a specified position, and the high-voltage busbar is moved so that its end contacts the limit plate 43. At this time, the position where the high-voltage busbar is aligned with the end of the static extrusion block 3 is the position that needs to be bent.

[0029] The driving mechanism 6 includes a bracket 61 and a vertical plate 64 fixed on the workbench 1. A motor 62 is installed on one side of the bracket 61. The motor 62 is configured as a forward and reverse motor. One end of the output shaft of the motor 62 is connected to a screw rod 63. One end of the screw rod 63 is rotatably mounted on the vertical plate 64 through a bearing.

[0030] A connecting plate 65 is threadedly connected to the outer wall of the screw rod 63 . A plurality of connecting columns 66 are connected to one side of the connecting plate 65 . One end of the connecting column 66 is connected to the dynamic extrusion block 51 .

[0031] The driving motor 62 drives the screw rod 63 to rotate, and the screw rod 63 drives the connecting plate 65 to move linearly, and pushes the dynamic extrusion block 51 to move horizontally through the connecting column 66; the rotating block 531 cooperates with the static extrusion block 3 to extrude the high-voltage busbar to deform and bend.

[0032] Two sets of parallel slide rails 7 are also installed on the workbench 1, and the dynamic extrusion block 51 is installed on the slide seat of the slide rail 7. The height of the slide rail 7 is greater than or equal to the height of the backing plate 2.

[0033] When in use, the high-voltage busbar to be bent is placed on the pad 2, and the cylinder 42 drives the limit plate 43 to move to the specified position, and the high-voltage busbar is moved so that its end contacts the limit plate 43. At this time, the position where the high-voltage busbar is aligned with the end of the static extrusion block 3 is the position that needs to be bent, and the high-voltage busbar is attached to the static extrusion block 3, and then the driving motor 62 drives the screw rod 63 to rotate, and the screw rod 63 drives the connecting plate 65 to move linearly, and the dynamic extrusion block 51 is pushed to move horizontally through the connecting column 66;

[0034] During the lateral movement of the dynamic extrusion block 51, the rotating block 531 first contacts the high-voltage busbar, and the high-voltage busbar pushes the rotating block 531 to rotate, so that the rotating block 531 rotates until the plane on one side is flush with the inner wall of the giveway groove 52, and the plane on one side of the rotating block 531 is in contact with the high-voltage busbar (that is, the roller 533 is in contact with the high-voltage busbar). As the dynamic extrusion block 51 continues to move, the rotating block 531 cooperates with the static extrusion block 3 to extrude the high-voltage busbar and bend it until the high-voltage busbar is in contact with the inclined surface of the static extrusion block 3, and the bending process of the high-voltage busbar is completed.

[0035] Example 2

[0036] See also Figure 2 and Figure 6 , the same as the first embodiment is not repeated here. In order to optimize the reset problem of the rotating block 531 after rotation in the first embodiment, in order to avoid manual reset of the rotating block 531 after bending, a reset mechanism 54 can be installed on the rotating block 531 and the dynamic extrusion block 51;

[0037] The reset mechanism 54 includes a first rotating plate 541 rotatably arranged on the dynamic extrusion block 51 and a second rotating plate 542 rotatably installed on the rotating block 531. A spring 543 is connected between the first rotating plate 541 and the second rotating plate 542. After bending and forming, the dynamic extrusion block 51 retreats and returns to its original position, and the resistance block 53 is separated from the high-voltage busbar. The elastic force generated by the spring returning to its original state pulls the rotating block 531 back (that is, the rotating block 531 is reversed), thereby realizing automatic resetting of the rotating block 531 and avoiding the cumbersome process of manually resetting the rotating block 531, thereby greatly improving the bending efficiency of the high-voltage busbar.
