The embodiments described below with reference to the drawings are exemplary, which are only used for explaining the present utility model, and cannot be construed as a limitation to the present utility model.

[0014] The embodiments of the present utility model are described below with reference to Figures 1 to 3 to illustrate the embodiments of the present utility model.

[0015] The present embodiment relates to a three-core wire shaping mechanism.

[0016] Referring to Figure 1 , the three-core wire shaping mechanism in this embodiment includes a first cylinder 1, a second cylinder 2, a shaping member 3 and a base 4; the first cylinder 1 is in transmission connection with the shaping member 3, the first cylinder 1 drives the shaping member 3 to move in the up-down direction, the second cylinder 2 is in transmission connection with the base 4, the second cylinder 2 drives the base 4 to move in the up-down direction, the base 4 is provided with a shaping groove, the shaping groove is configured to accommodate the lower end portion of the shaping member 3, and the shaping member 3 cooperates with the shaping groove to shape the three-core wire.

[0017] Compared with the prior art, the three-core wire shaping mechanism of the embodiment has a simple structure and a small volume. Shaping of the three-core wire is realized through the movement of each component in the up-down direction, and can be combined with a core wire protective layer peeling mechanism, reducing the volume of an automatic crimping machine for power terminals. Specifically, after the wire with three separated core wires is moved to the station of the three-core wire shaping mechanism, the first cylinder 1 drives the shaping member 3 to move downward, the second cylinder 2 drives the base 4 to move upward, as the shaping member 3 is inserted into the shaping groove, the three-core wire is squeezed by the shaping member 3 and the shaping base 4, forming an inverted "product" shape, that is, the ground wire is at the bottom, and the live wire and the neutral wire are at the top, which facilitates subsequent terminal crimping.

[0018] Referring to Figure 2 and 3In some embodiments, the lower end of the shaping component 3 includes a lower pressing head 31, a left pressing head 32, and a right pressing head 33. The lower end of the shaping component 3 has a lower pressing port 34, a left pressing port 35, and a right pressing port 36. The shaping groove includes a lower pressing groove 41, a left pressing groove 42, and a right pressing groove 43. The base 4 has a lower pressing surface 44, a left pressing surface 45, and a right pressing surface 46. The lower pressing head 31 and the lower pressing groove 41 are positioned opposite each other. The left pressing head 32 and the left pressing groove 42 are positioned opposite each other. The right pressing head 33 and the right pressing groove 43 are positioned opposite each other. The lower pressing port 34 and the lower pressing surface 44 are positioned opposite each other. The left pressing port 35 and the left pressing surface 45 are positioned opposite each other. The right pressing port 36 and the right pressing surface 46 are positioned opposite each other. In this embodiment, the cutting heads and pressure grooves of the shaping component 3 and the base 4 correspond to each other, as do the pressure ports and pressure surfaces, enabling efficient shaping of the three-core wire with a simple structure. Specifically, during the shaping of the three-core wire, the three core wires fall into the left pressure port 35, the lower pressure port 34, and the right pressure port 36, respectively. With the relative movement of the shaping component 3 and the base 4, the lower pressure cutting head 31, the left pressure cutting head 32, and the right pressure cutting head 33 are inserted into the lower pressure groove 41, the left pressure groove 42, and the right pressure groove 43, respectively. The three core wires are located on the lower pressure surface 44, the left pressure surface 45, and the right pressure surface 46, respectively, and are subjected to the pressure of the shaping component 3 and the base 4, thereby achieving the shaping of the three-core wire.

[0019] Reference Figure 1 and Figure 3 In some embodiments, the device further includes a first fixing block 5 and a second fixing block 6. The shaping component 3 is fixed to the second fixing block 6, and the first cylinder 1 is fixed to the first fixing block 5. The first cylinder 1 includes a piston rod that passes through the first fixing block 5, and the second fixing block 6 is fixedly connected to the piston rod. This embodiment provides a specific structural design for fixing the shaping component 3, achieving stable operation of the three-core wire shaping mechanism.

[0020] Reference Figure 1 In some embodiments, a guide post 7 is further included. The guide post 7 is fixedly connected to the second fixing block 6, and the guide post 7 passes through the first fixing block 5. The guide post 7 is slidably connected to the first fixing block 5. By setting the guide post 7, the movement of the first fixing block 5 can be stabilized, thus stabilizing the movement of the shaping part 3 and preventing collisions and friction between components due to unstable movement, which would reduce the processing accuracy and cause component damage.

[0021] Reference Figures 1 to 3In some embodiments, a wire pressing fork 8 is also included. The first cylinder 1 is tractively connected to the wire pressing fork 8, and the first cylinder 1 drives the wire pressing fork 8 to move in the up-down direction. The base 4 is provided with a wire pressing groove 47, which is used to accommodate the lower end of the wire pressing fork 8. The wire pressing fork 8 cooperates with the wire pressing groove 47 to press the wire. The wire pressing fork 8 can fix the wire and improve the stability of the three-core wire shaping process.
