In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Please see Figures 1-4This utility model provides an embodiment of an automotive terminal block stamping forming device, comprising a base 1 and a top plate 4. A lower die base 2 is detachably connected to the surface of the base 1, and a forming groove 3 is formed on the surface of the lower die base 2. An upper die base 5 is detachably connected to the lower surface of the top plate 4, and a stamping head 6 is fixedly connected to the lower surface of the upper die base 5. The stamping head 6 fits into the forming groove 3. An ejector plate 10 is slidably connected to the inner wall of the forming groove 3. A transmission cavity 11 is formed inside the lower die base 2, and an ejection mechanism is provided on the inner wall of the transmission cavity 11. The output end of the ejection mechanism is fixedly connected to the lower surface of the ejection plate 10. The ejection mechanism includes a fixing component 12, a sliding sleeve 13, a sliding rod 14, a guide wheel 15, a rotating shaft, and a cam 17. A connecting seat 9 is fixedly connected to the upper surface of the top plate 4. The top plate 4 is fixedly connected to the output end of an external hydraulic device through the connecting seat 9. A guide post 7 is fixedly connected to the surface of the base 1. A guide sleeve 8 is embedded in the surface of the top plate 4, and the guide post 7 slides within the guide sleeve 8. First, the external hydraulic device is connected through the connecting seat 9 on the top plate 4, and then the guide post 7 and the guide sleeve 8 cooperate. The device guides the flow of the terminal piece through a series of steps. First, it guides the flow by assembling a suitable detachable lower die holder 2 and upper die holder 5 according to the terminal specifications. This ensures the stamping head 6 aligns with the forming mold groove 3. Once the stamping head 6 contacts the terminal piece material placed in the forming mold groove 3, pressure is applied, causing the material to gradually conform to the inner wall shape of the forming mold groove 3 under the squeezing action of the stamping head 6, thus completing the terminal piece stamping process. The device provides stable guidance for the movement of the top plate 4 and the stamping head 6 through the cooperation of the guide column 7 and guide sleeve 8, preventing deviation during stamping. Simultaneously, the precise fit between the stamping head 6 and the forming mold groove 3 ensures the material completely conforms to the mold groove shape, significantly improving the forming accuracy of the terminal piece, reducing product scrap due to deviation, and guaranteeing stable product quality. Furthermore, the lower die holder 2 and base 1, and the upper die holder 5 and top plate 4 are all detachably connected. When processing different specifications of terminals, it is not necessary to replace the entire device; only a matching die holder needs to be quickly replaced. This not only reduces equipment investment costs but also allows the device to meet various production needs, broadening its applicability.

[0023] In this embodiment, a fixing member 12 is fixedly connected to the inner wall of the transmission cavity 11. A sliding sleeve 13 is embedded inside the fixing member 12. A sliding rod 14 is slidably connected to the inner wall of the sliding sleeve 13. The top end of the sliding rod 14 is fixedly connected to the lower surface of the ejector plate 10. A guide wheel 15 is rotatably connected to the bottom of the sliding rod 14. A cam 17 is rotatably connected to the inner wall of the transmission cavity 11, and the cam 17 abuts against the guide wheel 15. A return spring 18 is fixedly connected between the ejector plate 10 and the fixing member 12, and the return spring 18 is sleeved on the sliding rod 14. A fixing plate 19 is fixedly connected to the side wall of the lower mold base 2. A servo motor 20 is fixedly connected to the side wall of the fixing plate 19. A transmission rod 16 is fixedly connected to the power output end of motor 20. One end of the transmission rod 16 is fixedly connected to the shaft end of cam 17. After stamping is completed, the external hydraulic equipment drives the top plate 4, upper die base 5, and stamping head 6 to return to their original positions. Subsequently, the servo motor 20 fixed on the side wall fixing plate 19 of the lower die base 2 is started. The power output end of the servo motor 20 drives the transmission rod 16 to rotate. The transmission rod 16 then drives the cam 17, which is fixedly connected to its shaft end, to rotate in the transmission cavity 11. Since the cam 17 and the guide wheel 15 rotatably connected to the bottom of the slide rod 14 abut against each other, the rotation of the cam 17 will push the guide wheel 15 to move upward. The guide wheel 15 carries... The movable slide rod 14 slides upward within the sliding sleeve 13 embedded inside the fixed part 12. The top end of the slide rod 14 is fixedly connected to the lower surface of the ejector plate 10. Therefore, when the slide rod 14 moves upward, it pushes the ejector plate 10 to slide against the inner wall of the forming mold groove 3, ejecting the formed terminal piece from the forming mold groove 3, making it convenient for workers to remove the finished product. Finally, the servo motor 20 continues to rotate, and the return spring 18 pulls the ejector plate 10 and the slide rod 14 to return to their original positions, thus completing a complete work cycle. After the terminal piece is stamped, the finished terminal piece can be automatically ejected from the mold groove without manual removal, which reduces manual operation steps, reduces labor intensity, and avoids human error. To address the issues of low part removal efficiency and easy damage to finished products, this device effectively improves overall production efficiency. In terms of structure and maintenance, the sliding rod 14 and sliding sleeve 13 in the ejection mechanism slide together, and the guide wheel 15 and cam 17 roll and abut against each other, reducing component friction wear. The return spring 18 enables the ejection mechanism to return to its stable position, avoiding damage from hard collisions. Combined with the stable connection of each key component, it reduces the equipment failure rate and extends service life. At the same time, the connection method of each component of the device is simple and reasonable. For example, the top plate 4 can be quickly connected to external hydraulic equipment through the connecting seat 9. The detachable mold base is also easy to replace and repair. The staff can quickly deal with equipment problems, reducing maintenance difficulty and cost.

[0024] During operation, the device first connects to the external hydraulic equipment via the connecting seat 9 on the top plate 4. Guide pillars 7 and guide sleeves 8 are used for guidance. Then, a suitable detachable lower die holder 2 and upper die holder 5 are assembled according to the terminal specifications, ensuring the stamping head 6 aligns with the forming mold groove 3. When the stamping head 6 contacts the terminal piece material placed in the forming mold groove 3, pressure is applied, causing the material to gradually conform to the inner wall shape of the forming mold groove 3 under the squeezing action of the stamping head 6, completing the terminal piece stamping process. After stamping, the external hydraulic equipment drives the top plate 4, upper die holder 5, and stamping head 6 to return to their original positions. Subsequently, the servo motor 20 fixed on the side wall fixing plate 19 of the lower die holder 2 is activated. The power output of the servo motor 20 drives the transmission rod. When the transmission rod 16 rotates, it drives the cam 17, which is fixedly connected to its shaft end, to rotate in the transmission cavity 11. Since the cam 17 and the guide wheel 15, which is rotatably connected to the bottom of the slide rod 14, abut against each other, the rotation of the cam 17 will push the guide wheel 15 to move upward. The guide wheel 15 will drive the slide rod 14 to slide upward in the sliding sleeve 13 embedded in the fixing part 12. The top of the slide rod 14 is fixedly connected to the lower surface of the ejector plate 10. Therefore, when the slide rod 14 moves upward, it will push the ejector plate 10 to slide on the inner side wall of the forming mold groove 3, and eject the formed terminal piece from the forming mold groove 3, making it convenient for the staff to take out the finished product. Finally, the servo motor 20 continues to rotate, and the reset spring 18 pulls the ejector plate 10 and the slide rod 14 to reset, thus completing a complete work cycle.

[0025] After the terminal piece is stamped, it can be automatically ejected from the mold groove without manual removal. This reduces manual operation steps and labor intensity, and avoids the problems of low efficiency and easy damage to finished products caused by manual removal, effectively improving overall production efficiency. In terms of structure and maintenance, the sliding rod 14 and sliding sleeve 13 in the ejection mechanism slide and the guide wheel 15 and cam 17 roll and abut, reducing component friction wear. The return spring 18 can realize the smooth return of the ejection mechanism, avoiding damage from hard collisions. With the stable connection of each key component, the failure rate of the equipment is reduced and the service life is extended. At the same time, the connection method of each component of the device is simple and reasonable. For example, the top plate 4 can be quickly connected to external hydraulic equipment through the connecting seat 9, and the detachable mold base is also convenient for replacement and maintenance. Staff can quickly handle equipment problems, reducing maintenance difficulty and costs. The device provides stable guidance for the movement of the top plate 4 and the stamping head 6 through the cooperation of the guide column 7 and the guide sleeve 8, avoiding deviation during the stamping process. At the same time, the stamping head 6 and the forming mold groove 3 fit precisely, ensuring that the raw material can completely conform to the shape of the mold groove, greatly improving the forming accuracy of the terminal piece, reducing product scrap due to deviation, and ensuring stable product quality. On the other hand, the lower mold base 2 and the base 1, and the upper mold base 5 and the top plate 4 are all detachably connected. When different specifications of wiring terminals need to be processed, there is no need to replace the entire device. Only the matching mold base needs to be quickly replaced. This not only reduces the equipment investment cost, but also allows the device to meet a variety of production needs and has a wider range of applications.

[0026] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
