Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] The following is combined Figures 1 to 4 The embodiments of this utility model are described below.

[0017] This embodiment relates to a three-core wire shaping mechanism.

[0018] The three-core wire shaping mechanism in this embodiment includes a fixed frame 9, a vertical movement mechanism, a front-back movement mechanism, a first upper shaping component 3, a second upper shaping component 4, a first lower shaping component 5, and a second lower shaping component 6. The vertical movement mechanism is fixed to the fixed frame 9, and it drives the first upper shaping component 3, the second upper shaping component 4, the first lower shaping component 5, and the second lower shaping component 6 to reciprocate in the vertical direction. The front-back movement mechanism drives the second upper shaping component 4 and the second lower shaping component 6 to reciprocate in the front-back direction. The bottom surface of the first upper shaping component 3 is provided with a first block 310, a first groove 330, and a second block 320 in sequence along the left-right direction. The middle part of the first lower shaping component 5 is provided with a first notch 510 and a second notch 520. The lower shaping member 5 has a first channel 530 and a second channel 540 on its left and right sides. The first block 310 and the second block 320 can be inserted into the first notch 510 and the second notch 520 respectively. The front end of the second lower shaping member 6 has a third block 610, a second groove 630 and a fourth block 620 arranged sequentially in the left and right direction. The rear end of the first lower shaping member 5 can be inserted into the second groove 630, so that the third block 610 and the fourth block 620 are inserted into the first channel 530 and the second channel 540 respectively. The bottom surface of the second upper shaping member 4 has a fifth block 410 and a sixth block 420 spaced apart in the left and right direction. In the left and right direction, the third block 610 and the fourth block 620 are both located between the fifth block 410 and the sixth block 420.

[0019] The three-core wire shaping mechanism of this embodiment has a relatively simple and compact structure, which can stably shape the three-core wire. Specifically, after the three core wires, which have been separated laterally, enter the three-core wire shaping station, the front-back motion mechanism drives the second upper shaping member 4 to move forward, so that the fifth block 410 and the sixth block 420 are located in front of the middle of the first lower shaping member 5 in the front-back direction. The up-down motion mechanism drives the first lower shaping member 5 and the second lower shaping member 6 to move upward, so that the three core wires are located on the first lower shaping member 5 and the second lower shaping member 6. The up-down motion mechanism drives the first upper shaping member 3 and the second upper shaping member 4 to move downward. The first block 310 and the second block 320 are respectively inserted into the first notch 510 and the second notch 520. The first groove 330 accommodates the middle part of the first lower shaping member 5. The core wire located in the middle is located in the first groove 330 and is shaped by the downward pressure of the first upper shaping member 3. Then, the front-to-back motion mechanism drives the second lower shaping component 6 forward, causing the third block 610 and the fourth block 620 to insert into the first channel 530 and the second channel 540 respectively. The core wires on both sides are located at the bottom of the first channel 530 and the second channel 540 respectively, and are shaped by the forward pressure of the second lower shaping component 6. Then, the front-to-back motion mechanism drives the second upper shaping component 4 backward, and the fifth block 410 and the sixth block 420 pull the core wires on both sides backward, shaping the ends of the core wires along the front-to-back direction. After shaping is completed, the front-to-back motion mechanism drives the second lower shaping component 6 backward, the up-and-down motion mechanism drives the first upper shaping component 3 and the second upper shaping component 4 upward, and the up-and-down motion mechanism drives the first lower shaping component 5 and the second lower shaping component 6 downward. The wire leaves the three-core wire shaping station, and the three-core wire shaping mechanism waits for the next wire to enter the station for shaping.

[0020] In some embodiments, the up-and-down movement mechanism includes a first cylinder 11 and a third cylinder 21, and the forward-and-backward movement mechanism includes a second cylinder 12 and a fourth cylinder 22. The first cylinder 11 and the third cylinder 21 are respectively fixed on the fixed frame 9. The first cylinder 11 is operatively connected to the first lower shaping member 5 and the second cylinder 12, and the first cylinder 11 drives the first lower shaping member 5 and the second cylinder 12 to reciprocate in the up-and-down direction. The second cylinder 12 is operatively connected to the second lower shaping member 6, and the second cylinder 12 drives the second lower shaping member 6 to reciprocate in the forward-and-backward direction. The third cylinder 21 is operatively connected to the first upper shaping member 3 and the fourth cylinder 22, and the third cylinder 21 drives the first upper shaping member 3 and the fourth cylinder 22 to reciprocate in the up-and-down direction. The fourth cylinder 22 is operatively connected to the second upper shaping member 4, and the fourth cylinder 22 drives the second upper shaping member 4 to reciprocate in the forward-and-backward direction.

[0021] The three-core wire shaping mechanism in this embodiment, through the reasonable arrangement of cylinders, can stably shape the three-core wire. Specifically, after the three core wires, which have been separated laterally, enter the three-core wire shaping station, the fourth cylinder 22 drives the second upper shaping member 4 to move forward, so that the fifth block 410 and the sixth block 420 are positioned in front of the middle of the first lower shaping member 5. The first cylinder 11 drives the second cylinder 12 and the first lower shaping member 5 to move upward, so that the three core wires are positioned on the first lower shaping member 5 and the second lower shaping member 6. The third cylinder 21 drives the fourth cylinder 22 and the first upper shaping member 3 to move downward. The first block 310 and the second block 320 are respectively inserted into the first notch 510 and the second notch 520. The first groove 330 accommodates the middle of the first lower shaping member 5. The core wire located in the middle is located in the first groove 330 and is shaped by the downward pressure of the first upper shaping member 3. Then, the second cylinder 12 drives the second lower shaping component 6 to move forward, causing the third block 610 and the fourth block 620 to insert into the first channel 530 and the second channel 540 respectively. The core wires on both sides are located at the bottom of the first channel 530 and the second channel 540 respectively, and are shaped by the forward pressure of the second lower shaping component 6. Then, the fourth cylinder 22 drives the second upper shaping component 4 to move backward, and the fifth block 410 and the sixth block 420 pull the core wires on both sides backward, so that the ends of the core wires are shaped along the front-back direction. After the shaping is completed, the second cylinder 12 drives the second lower shaping component 6 to move backward, the third cylinder 21 drives the fourth cylinder 22 and the first upper shaping component 3 to move upward, and the first cylinder 11 drives the second cylinder 12 and the first lower shaping component 5 to move downward. The wire leaves the three-core wire shaping station, and the three-core wire shaping mechanism waits for the next wire to enter the station for shaping.

[0022] In some embodiments, the three-core wire shaping mechanism further includes a first fixed base 13 and a second fixed base 23. A first cylinder 11 is operatively connected to the first fixed base 13, driving the first fixed base 13 to reciprocate vertically. The first lower shaping member 5 and the second cylinder 12 are fixed to the first fixed base 13. A third cylinder 21 is operatively connected to the second fixed base 23, driving the second fixed base 23 to reciprocate vertically. The first upper shaping member 3 and the fourth cylinder 22 are fixed to the second fixed base 23. By providing the first fixed base 13 and the second fixed base 23, the various components can be connected more stably and conveniently, which is beneficial for the maintenance and stable operation of the three-core wire shaping mechanism.

[0023] In some embodiments, the rear side of the first upper shaping member 3 is provided with a pressure block, and the rear end of the first lower shaping member 5 is provided with a pressure surface, the pressure block and the pressure surface being positioned correspondingly. Providing a pressure block and a pressure surface helps to shape the end of the core wire located in the middle into a direction along the front-back direction, which is beneficial for the stable operation of subsequent riveting. Specifically, when the first upper shaping member 3 moves downward with the second fixing seat 23, and the first block 310 and the second block 320 are respectively inserted into the first notch 510 and the second notch 520, and the first groove 330 accommodates the middle part of the first lower shaping member 5, the pressure surface moves downward. The end of the core wire located in the middle is located between the pressure block and the pressure surface, and is shaped into a direction along the front-back direction by the downward pressure of the first upper shaping member 3.

[0024] In some embodiments, the top surface of the front portion of the first lower shaping member 5 is provided with an arc-shaped recess 550, which is used to accommodate the lower end of the wire. Providing the arc-shaped recess 550 helps to fix the position of the wire, improving the stability and accuracy of the three-core wire shaping process.

[0025] In some embodiments, a wire pressing assembly is further included, comprising an upper wire pressing component 71 and a lower wire pressing component 72. The upper wire pressing component 71 is fixed to the second fixing base 23, and the lower wire pressing component 72 is fixed to the first fixing base 13. A fixing groove is formed between the upper wire pressing component 71 and the lower wire pressing component 72 for fixing the wire. Using a wire pressing assembly to fix the wire helps improve the stability and accuracy of the three-core wire shaping process.

[0026] In some embodiments, the system further includes a guide post 8 and a third fixed seat 24. The third fixed seat 24 is fixed to the fixed frame 9. The third cylinder 21 includes a guide rod, which is fixed to the third fixed seat 24 and passes through the third fixed seat 24. The second fixed seat 23 is fixedly connected to the guide rod. The guide post 8 is fixedly connected to the first fixed seat 13 and passes through the third fixed seat 24 and the second fixed seat 23. The second fixed seat 23 is slidably connected to the guide post 8. The fixed connection method of this embodiment is beneficial in maintaining the lateral relative position of the first fixed seat 13 and the second fixed seat 23, which helps to improve the stability and accuracy of the three-core wire shaping mechanism.
