Embodiment 1

[0022] Please refer to Figures 1 - 5 As shown in the figure, the present invention provides an anti-wear bus bar bending machine, which includes a fixed frame 8. A hydraulic cylinder 7 is fixedly installed on the top of the fixed frame 8. The output end of the hydraulic cylinder 7 is fixedly installed with a moving plate 6.

[0023] In this technical solution, through the setting of the bending bottom die 3, the busbar to be bent can be supported. Through the settings of the hydraulic cylinder 7, the moving plate 6, the moving guide plate 16, the guide wheel 15, the fixed rod 14, the U-shaped moving rod 13, the L-shaped moving rod 22, the second spring 25, the fixed cylinder 21, the push plate 20, the fixed baffle 19, the bending bottom die 3 and the bending groove 2, the placed busbar can be effectively straightened, effectively avoiding the influence of the subsequent bending quality due to the offset and inclination of the placed busbar. At the same time, the effect of effectively bending the busbar is achieved.

[0024] On the basis of Embodiment 1, as shown in the present utility model Figures 1 - 5 shown, accommodation holes 24 are respectively opened at both ends of the back surface of the bending bottom die 3. The surface of the U-shaped moving rod 13 is movably connected to the surface of the accommodation hole 24. A first spring 23 is fixedly connected between the surface of the accommodation hole 24 and the front surface of the U-shaped moving rod 13. The upper ends on both sides of the support table 1 are respectively movably connected through bearings with adjusting screws 10.

Both ends of the top of the support table 1 are fixedly connected with guiding cross bars 9. The middle end of the limit baffle 4 is movably connected to the surface of the guiding cross bar 9. A limit groove 27 is opened at the top of the L-shaped moving rod 22. The top of the inner cavity of the fixed cylinder 21 is fixedly connected with a limit block 26. The surface of the limit block 26 is movably connected to the surface of the limit groove 27. The upper end of the fixed frame 8 is fixedly connected with a guiding vertical rod 17. The surface of the moving plate 6 is movably connected to the surface of the guiding vertical rod 17. Strengthening rods 18 are respectively fixedly connected to the lower ends on both sides of the moving guide plate 16. The upper ends of the strengthening rods 18 are fixedly connected to the surface of the moving plate 6. A support block is fixedly connected to the bottom of the outer surface of the support table 1, and the number of the support blocks is four.

[0025] In this technical solution, through the settings of the accommodation hole 24 and the first spring 23, the purpose of supporting and guiding the U-shaped moving rod 13 is achieved, avoiding the inclination of the U-shaped moving rod 13 during the movement. At the same time, under the action of the movement of the U-shaped moving rod 13, the first spring 23 can be compressed, and the first spring 23 exerts a tension force on the U-shaped moving rod 13, so that the U-shaped moving rod 13 can be moved and reset subsequently. Through the setting of the limit baffle 4, the two sides of the busbar placed on the top of the bending bottom die 3 can be effectively limited. Through the setting of the adjusting screw 10, by manipulating the rotation of the adjusting screw 10, the limit baffle 4 can be driven to move, facilitating the adjustment of the position of the limit baffle 4 by the operator according to the length of the busbar. Through the setting of the support plate 11, the purpose of supporting the adjusting screw 10 is achieved, effectively avoiding the inclination of the adjusting screw 10 due to the force. Through the setting of the guiding cross bar 9, the purpose of guiding the limit baffle 4 is achieved, effectively avoiding the inclination of the limit baffle 4 during the movement. Through the settings of the limit groove 27 and the limit block 26, the effective limit between the fixed cylinder 21 and the L-shaped moving rod 22 can be achieved, avoiding the loosening of the fixed cylinder 21 from the surface of the L-shaped moving rod 22. Through the setting of the guiding vertical rod 17, the purpose of guiding the moving plate 6 is achieved, avoiding the inclination of the moving plate 6 during the movement. Through the setting of the reinforcing rod 18, the connection strength between the moving guide plate 16 and the moving plate 6 is effectively improved.

[0026] The working principle of this utility model is as follows: Through the setting of the bending bottom die 3, the busbar to be bent and processed can be supported. By controlling the elongation of the hydraulic cylinder 7, the moving plate 6, the bending press die 5 and the moving guide plate 16 can be pushed to move downward. During the movement of the moving guide plate 16, it can push the guide wheel 15, the fixed rod 14, the U-shaped moving rod 13, the L-shaped moving rod 22, the second spring 25, the fixed cylinder 21 and the push plate 20 to move through the inclined plane. Thus, the push plate 20 can contact the back surface of the busbar in advance under the action of the movement, and push the busbar to contact the surface of the fixed baffle 19, so as to effectively straighten the busbar placed on the top of the bending bottom die 3, effectively avoiding the influence of the offset and inclination of the busbar placement on the subsequent bending quality. Subsequently, under the continuous elongation of the hydraulic cylinder 7, the bending press die 5 can contact the top of the busbar, and the middle part of the busbar can be pressed down into the bending groove 2 in the middle of the bending bottom die 3, thus achieving the effect of effectively bending the busbar. At the same time, through the setting of the polytetrafluoroethylene anti-wear strip 12, the stress points at both ends of the busbar can be supported during the bending process. And because the material of the polytetrafluoroethylene anti-wear strip 12 itself is polytetrafluoroethylene, it has good self-lubricating performance and a small friction coefficient, thus effectively reducing the probability of wear on the stress points at both ends during the busbar bending process, which is beneficial for the operator to use.
