Due to the narrow space around the terminal, the previous terminal bending mechanism is large in size and easy to damage the material. At the same time, manual bending cannot guarantee the dimensional stability of bending, and the production efficiency is low.

Then, two first bending cylinders are started, and their telescopic ends drive two first bending parts to extend into the motor. Then, the second bending cylinder is started, and its telescopic end drives the second bending part to move forward and abut against the terminal. Then, the first bending cylinder retracts, driving the first bending part to bend the terminal. Summary of the Utility Model

By setting the forward moving cylinder 1, during operation, its telescopic end will push the mounting plate 7 forward, thereby driving the equipment seat 8 and the first bending cylinder 9 and the second bending cylinder 10 inside it forward. Then, start the two first bending cylinders 9, and their telescopic ends drive the two first bending members 11 to extend into the motor. Start the two side moving cylinders 5. The side moving cylinders 5 drive the first bending member 11 and the second bending member 12 at the ends of the first bending cylinder 9 and the second bending cylinder 10 to enclose the motor terminal. Then, start the second bending cylinder 10, and its telescopic end drives the second bending member 12 to move forward and abut against the terminal. Then, the first bending cylinder 9 retracts, driving the first bending member 11 to bend the terminal.

[0023] Please refer to Figures 1 - 3, in this embodiment, guiding seats 13 are provided at the front positions of the upper surfaces of the two guiding plates 4. The upper surface of the guiding seat 13 is slidably connected to the bottom surface of the equipment seat 8. Guiding rails 14 are installed at the side positions of the upper surfaces of the two guiding plates 4 located at the sides of the guiding seat 13. The guiding rails 14 are slidably connected to the equipment seat 8. By providing the guiding rails 14 and the guiding seats 13, when the side-shifting cylinder 5 pushes the equipment seat 8 to move, the guiding rails 14 and the guiding seats 13 can limit the moving direction of the equipment seat 8, improving the operation precision of the equipment. At the front side position of the forward-shifting cylinder 1, a bottom plate 15 is provided. The bottom surface of the bottom plate 15 is connected to the external workbench. At the upper surface of the bottom plate 15 and below the two equipment seats 8, columns 16 are provided. The top surface of the column 16 is provided with a long plate 17. A limiting rail 18 is installed on the upper surface of the long plate 17. The bottom surface of the mounting plate 7 is slidably connected to the limiting rail 18. By providing the limiting rail 18, when the forward-shifting cylinder 1 operates, the mounting plate 7 will slide along the direction of the limiting rail 18, improving the moving precision and ensuring that the first bending part 11 can smoothly extend into the motor. On the upper surface of the bottom plate 15, symmetrically arranged electric guide rails 19 are installed. The upper surface of the electric guide rail 19 is connected with a tooling plate 20 through an electric slider. At the right position of the upper surface of the tooling plate 20, a positioning seat 21 for fixing the motor is provided. By providing the electric guide rail 19, during operation, it can drive the tooling plate 20 to move to the working position, thus realizing the continuous automatic operation of the equipment.

[0024] Please refer to Figures 1 - 4 , in this embodiment, columns 22 are installed on the front and rear sides of the upper surface of the bottom plate 15 at the positions of the electric guide rails 19. The top surface of the column 22 is provided with a fixing plate 23. At the middle position of the bottom surface of the fixing plate 23, a positioning cylinder 24 is provided. The telescopic end of the positioning cylinder 24 is provided with a positioning pin 25. By providing the positioning cylinder 24, after the motor on the surface of the tooling plate 20 moves to the working position, the positioning cylinder 24 is started, and its telescopic end drives the positioning pin 25 to position the motor, avoiding the deviation of the bending position caused by the shaking of the motor during bending. The gap between the first bending part 11 and the second bending part 12 is slightly larger than the thickness of the terminal. By leaving a certain gap between the first bending part 11 and the second bending part 12, it can ensure that the bent terminal can pass through smoothly and ensure that the terminal does not break during the bending process. Both the first bending part 11 and the second bending part 12 are made of SKD11 material. By using SKD11 material to make the first bending part 11 and the second bending part 12, they can have high hardness and high wear resistance, greatly increasing the service life of the parts.

[0025] When working, by setting the guiding track 14 and the guiding seat 13, when the side-shifting cylinder 5 pushes the equipment seat 8 to move, the guiding track 14 and the guiding seat 13 can limit the moving direction of the equipment seat 8, improve the operation precision of the equipment. And by setting the limiting track 18, when the forward-shifting cylinder 1 operates, the mounting plate 7 will slide along the direction of the limiting track 18, improving the moving precision to ensure that the first bending piece 11 can smoothly extend into the motor. And by setting the electric guide rail 19, it can drive the tooling plate 20 to move to the working position during operation, thus realizing the continuous automatic operation of the equipment. And by setting the positioning cylinder 24, after the motor on the surface of the tooling plate 20 moves to the working position, start the positioning cylinder 24, and its telescopic end drives the positioning pin 25 to position the motor, avoiding the deviation of the bending position caused by the shaking of the motor during bending. And by leaving a certain gap between the first bending piece 11 and the second bending piece 12, it can ensure that the bending terminal can pass through smoothly, ensuring that the terminal does not break during the bending process. And by using SKD11 material to make the first bending piece 11 and the second bending piece 12, it can make them have high hardness and high wear resistance, greatly increasing the service life of the components.

[0026] Through the above steps, by setting the forward-shifting cylinder 1, its telescopic end will push the mounting plate 7 forward during operation, thus driving the equipment seat 8 and the first bending cylinder 9 and the second bending cylinder 10 inside it to move forward. Then start the two first bending cylinders 9, and their telescopic ends drive the two first bending pieces 11 to extend into the motor. Start the two side-shifting cylinders 5, and the side-shifting cylinders 5 drive the first bending pieces 11 and the second bending pieces 12 at the ends of the first bending cylinder 9 and the second bending cylinder 10 to enclose the motor terminals. Then start the second bending cylinder 10, and its telescopic end drives the second bending piece 12 to move forward and press against the terminal. Then the first bending cylinder 9 pulls back, driving the first bending piece 11 to bend the terminal, so as to solve the problems that the existing terminal bending is improved on the basis of manual bending. Due to the narrow space around the terminal, the previous terminal bending mechanism is large in size and easy to damage the material. At the same time, manual bending cannot guarantee the dimensional stability of bending and has low production efficiency.
