Detailed implementation manners

[0023] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0024] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0025] As Figures 1-5 shown, the embodiments of the present utility model provide a manufacturing device for a commutator copper shell, including: a base 1, on which two electric push rods 2, a motor 3 are fixedly installed, and a forming assembly 4 is slidably arranged. The forming assembly 4 includes a plurality of forming blocks 5 that are slidably engaged with each other. Two springs 6 are fixedly installed between every two adjacent forming blocks 5. The output ends of the two motors 3 are both fixedly installed with threaded rods 7. Four connecting blocks 8 that are respectively threadedly engaged with the two threaded rods 7 are fixedly installed on both sides of the forming assembly 4. The output ends of the two electric push rods 2 are fixedly installed with a sliding plate 9. A plurality of mold cores 10 are fixedly installed on the sliding plate 9. A sliding strip 11 is slidably arranged on one side of the base 1. Two rotating square rods 12 are rotatably arranged between the sliding strip 11 and the sliding plate 9. A plurality of pushing frames 13 are fixedly installed on one side of the sliding strip 11.

[0026] In this embodiment, specifically: Four supporting parts for supporting the base 1 are provided on the lower surface of the base 1. Two first guiding rods 14 for guiding a plurality of forming blocks 5 are fixedly installed on the lower side of the base 1. A plurality of springs 6 are respectively sleeved on the circumferences of the two first guiding rods 14.

[0027] In this embodiment, specifically: Both of the two motors 3 are located on the lower side of the base 1. External threads that are in threaded fit with the four connecting blocks 8 are provided at both ends of the threaded rod 7.

[0028] In this embodiment, specifically: Sliding parts that are in sliding fit with the inside of the base 1 are provided on both sides of the tops of the plurality of forming blocks 5. Grooves for copper shell forming are provided on the plurality of bases 1.

[0029] In this embodiment, specifically: Both of the two electric push rods 2 are located on the lower side of the base 1. The output ends of the two electric push rods 2 penetrate through the base 1. Two second guiding rods 15 that both penetrate through the sliding strip 11 are fixedly installed on one side of the base 1. The sliding strip 11 is of an L-shaped structure.

[0030] In this embodiment, specifically: Two rotating square rods 12 are located on both sides of the sliding strip 11. The plurality of pushing frames 13 are all of a Y-shaped structure. The pushing frames 13 are located above the forming assembly 4.

[0031] When the present utility model is working: When the device needs to perform automatic blanking, at this time, the formed copper shell is located between the plurality of forming blocks 5. Then, the motor 3 is started. The start of the motor 3 drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the four connecting blocks 8 to slide away from each other. At this time, the plurality of springs 6 push the plurality of forming blocks 5 to slide away from each other. After the plurality of forming blocks 5 move away from each other, the copper shell formed inside the forming blocks 5 at this time disengages from the plurality of forming blocks 5, and thus the blanking of the copper shell is completed.

[0032] When it is necessary to push out the formed copper shell, after the plurality of forming blocks 5 slide away from each other, the copper shell located inside the forming blocks 5 may not necessarily automatically disengage from the forming blocks 5 at this time. Therefore, it is necessary to push out the copper shell. At this time, the electric push rod 2 is started. The start of the electric push rod 2 drives the sliding plate 9 and the die core 10 to slide away from the base 1. At this time, the sliding plate 9 pulls the rotating square rod 12 to rotate, and the sliding strip 11 and the pushing frame 13 slide. During the sliding process of the pushing frame 13, the formed copper shell is pushed. After the copper shell is pushed by the pushing frame 13, the copper shell disengages from the forming blocks 5 at this time, and thus the blanking of the copper shell is completed.

[0033] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the said claims.
