[0040] In view of the technical problems described in the background art, a terminal bending device is proposed for shaping and bending a terminal roll, such as Figure 1-7 As shown, it is a horizontal structure for unfolding the terminal material roll. When the terminal material roll is incoming, it is in the form of a coil. The terminal material roll is installed on the unwinding mechanism 2. After the terminal material roll is pulled to the material roll channel, it is moved to the transmission mechanism 4. The terminal material roll is driven by the transmission mechanism 4 to move on the terminal material roll channel 3. The terminal material roll moves to the shaping mold 5 on the terminal material roll channel 3. Under the action of the upper mold 6 and the lower mold 7, the terminal material roll is shaped into a desired shape. Figure 1 It is the shaping process of the terminal coil.

[0041] The terminal bending equipment is used to realize automatic shaping of terminal coils, and the terminal coils with horizontal structures are processed and shaped into the required terminal bending structures to meet production needs.

[0042] refer to Figure 13-17As shown, the upper shaping plate 8 is provided with a first upper shaping portion 12 for pre-shaping the terminal material roll upward, the upper shaping plate 8 is provided with a second upper shaping portion 13 for shaping the terminal material roll upward, the upper shaping plate 8 is provided with a third upper shaping portion 14 for shaping the terminal material roll upward, the upper shaping plate 8 is provided with an upper bending portion 15 for bending the terminal material roll downward, and the upper shaping plate 8 is provided with an upper trimming portion 16 for trimming the terminal material roll; the lower shaping plate The plate 9 is provided with a first lower shaping portion 17 that is shaped in cooperation with the first upper shaping portion 12, the lower shaping plate 9 is provided with a second lower shaping portion 18 that is shaped in cooperation with the second upper shaping portion 13, the lower shaping plate 9 is provided with a third lower shaping portion 19 that is shaped in cooperation with the third upper shaping portion 14, the lower shaping plate 9 is provided with a lower bending portion 20 that is shaped in cooperation with the upper bending portion 15, and the lower shaping plate 9 is provided with a lower trimming portion 21 that is coordinated with the upper trimming portion 16.

[0043] In the process of preparing the connector, it is necessary to shape and adjust the terminal from a horizontal structure, and shape the horizontal structure into a structure required for production. In the actual shaping process, five steps are involved in shaping the terminal roll. The first step is to coordinate and shape the first upper shaping part 12 and the first lower shaping part 17. The first step is to pre-shape the terminal roll upward, that is, to bend the terminal roll from the horizontal direction to an inclined direction, and to tilt the terminal roll upward from the horizontal to a certain angle; the second step is to coordinate and shape the second upper shaping part 13 and the second lower shaping part 18, to bend the terminal roll, and then the inclination angle of the terminal roll is further increased. the third step is that the third upper shaping portion 14 and the third lower shaping portion are not coordinated to shape, the terminal material roll is bent, and the terminal is bent into a vertical state. Under the action of the first step, the second step and the third step, the terminal material roll is bent and shaped from a horizontal state; the fourth step is that the upper bending portion 15 and the lower bending portion 20 bend the terminal downward to shape the terminal, and the upper side of the terminal and the side of the terminal form a 90° angle to meet the production needs. The fifth step is that the upper trimming portion 16 and the lower trimming portion 21 cooperate to further trim the position of the terminal to meet the requirement that the upper side of the terminal and the side of the terminal form a 90° angle.

[0044] The first upper shaping part 12 is provided with a first upper shaping tooth arranged obliquely along its upper position, and the first lower shaping part 17 is provided with a first lower shaping tooth matched with the first upper shaping tooth. The second upper shaping part 13 is provided with a second upper shaping tooth arranged obliquely along its upper position, and the second lower shaping part 18 is provided with a second lower shaping tooth matched with the second upper shaping tooth. The third upper shaping part 14 is provided with a third upper shaping tooth arranged upright along its upper position, and the third lower shaping part 19 is provided with a third lower shaping tooth matched with the third upper shaping tooth.

[0045] Since the terminal stock roll designed in production has a linearly arranged pin structure, the pins need to be tilted and bent during the shaping process. To this end, by designing shaping teeth to cooperate with each other in limiting, when the upper and lower molds 7 are closed, the limiting effect of the structure bends and shapes the pins on the terminal stock roll. Specifically, the first upper shaping tooth and the first lower shaping tooth are set with an inclination angle according to the pre-shaping, such as the pre-shaping angle of the first step is 45°, and the pins on the terminal stock roll are bent and tilted by 45°. The second upper shaping tooth and the second lower shaping tooth are used to further increase the inclination angle, such as the shaping angle of the second step is 70°, and the pins on the terminal stock roll are bent and tilted to 70°. The shaping angle of the third upper shaping tooth and the third lower shaping tooth is 90°, that is, the pins on the terminal stock roll are bent to a 90° position.

[0046] The upper bending portion 15 is a convex block protruding downward, and the lower bending portion 20 is a concave notch. The upper bending portion 15 is driven to press the terminal material roll downward and bend it.

[0047] In the fourth step, the pins on the terminal coil need to be bent downward. During implementation, the pins on the terminal coil are bent downward to a 90° position by pressing down the protrusions.

[0048] The upper trimming part 16 is pressed downward to drive the lower trimming part 21 to move laterally to trim the terminal coil. The upper trimming part 16 is a driving block, and the lower trimming part 21 is used to further trim the side of the terminal coil. When the upper mold 6 and the lower mold 7 are closed, the upper trimming part 16 drives the lower trimming part 21 to move laterally to trim the pin of the terminal coil to 90° to meet the subsequent pin insertion operation.

[0049] Specifically, Figure 18-19 As shown, the unloading mechanism 2 includes a unloading motor 22, a unloading tray 23 arranged on the unloading motor 22, and a support strip 24 arranged below the unloading tray 23. The unloading tray 23 is wound around the terminal material roll, and the support strip 24 is used to support the terminal material roll.

[0050] The terminal coils in production are transported to the production site in the form of coils. The terminal coils are installed on the discharge tray 23, and the terminal coils are discharged by the rotation of the discharge motor 22. The support strips 24 support the terminal coils to prevent the terminal coils from bending and deforming under their own weight.

[0051] The transmission mechanism 4 includes a transmission motor 25 and a transmission wheel 26 disposed at a rotating end of the transmission motor 25 . The transmission wheel 26 is provided with transmission teeth for driving the terminal coil.

[0052] Since the produced terminal roll has holes for meshing transmission on one side, the transmission mechanism 4 used is configured with transmission teeth on the circumference of the transmission wheel 26, and the transmission teeth and the holes of the terminal roll are meshed for transmission, thereby driving the movement of the terminal roll.

[0053] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
