An eccentric driving column 6 is arranged on the driving wheel, a driving block 3 is matched with the driving motor 2, and the driving block 3 is provided with a waist-shaped hole 7 for cooperating with the driving column 6.

[0033] A first guide rail 4 is fixed on the frame 1, and the first guide rail 4 plays a guiding role for the driving block 3. When the driving motor 2 works, it drives the driving column 6 to rotate. The eccentric driving column 6 cooperates with the waist-shaped hole 7 to drive the driving block 3 to make a reciprocating linear motion along the first guide rail 4. Press the touch switch 38 once, and the driving motor 2 drives the driving block 3 to make a reciprocating linear motion along the first guide rail 4 once.

[0034] The driving component is fixedly connected with a forming component. The forming component includes: a guiding block 8 fixedly connected to the driving block 3, a first positioning block 9 slidably connected to the guiding block 8, and the guiding block 8 is provided with a first positioning groove 14 for the first positioning block 9 to slide.

[0035] As Figure 3 shown, the driving block 3 is provided with a limiting part 15 for cooperating with the first positioning block 9. When the first positioning block 9 moves downward, the limiting part 15 controls the limit position of the movement of the first positioning block 9 to avoid the phenomenon of crushing the terminal.

As Figure 3 shown, the driving block 3 is fixedly connected with a first forming block 11, and the first positioning block 9 is provided with a first positioning groove 14 for the first forming block 11 to slide.

[0037] As Figure 2 shown, a lower module component is fixedly connected to the frame 1, the lower module component is arranged below the driving component, one end of a first unloading knife 12 is hinged to the lower module component, and the driving block 3 is fixedly connected with a first matching block 13 for cooperating with the other end of the first unloading knife 12.

[0038] The driving block 3 drives the first matching block 13 to move downward. The first matching block 13 is provided with a driving groove, and the driving groove cooperates with the first unloading knife 12 to drive the first unloading knife 12 to rotate along the hinge point to drive the formed terminal to move upward, solving the problem that there is no upward pushing action after forming in the past and reducing the phenomenon of wire breakage.

[0039] The lower module assembly includes: a support table 34 fixed to the frame 1, a detachable forming die 35 fixed on the support table 34, and a rotating table 36 fixed on the support table 34. The upper surface of the forming die 35 is provided with an M-shaped forming opening, which is directly below the first forming block 11. The first forming block 11 moves downward to cooperate with the M-shaped forming opening to crimp and form the terminal. The rotating table 36 is fixedly connected to the support table 34, and the rotating table 36 is hinged to the first ejector blade 12.

[0040] As Figure 1 shown, a terminal feeding assembly is fixed on the frame 1. The terminal feeding assembly includes: a first slide rail 17 for feeding materials, the first slide rail 17 is fixedly connected to the frame 1, and a first air cylinder 18 is fixed on the first slide rail 17.

[0041] A first driving claw 16 is hinged to the telescopic rod of the first air cylinder 18. The telescopic rod drives the first driving claw 16 to move along the length direction of the guide rail. The terminal includes a large end and a small end.

[0042] As Figure 3 shown, the first driving claw 16 is provided with a driving groove. The telescopic rod drives the first driving claw 16 to move towards the first positioning groove 14. The driving groove contacts the small end of the terminal and drives the terminal forward.

[0043] When the telescopic rod drives the first driving claw 16 to retract, the driving groove contacts the large end of the terminal. The first driving claw 16 rotates along the hinge point, and finally the driving groove moves to the small end of the terminal. In this way, each time the first air cylinder 18 moves, it drives one terminal to move to the processing station.

[0044] As Figures 1 to 4 shown, during operation, the two wires to be crimped are placed at the M-shaped forming opening of the forming die 35. The touch switch 38 is turned on, and the driving motor 2 rotates to drive the driving column 6 to rotate. The driving block 3 moves downward, driving the first positioning block 9 to move downward. At the same time, the first matching block 13 drives the first ejector blade 12 to move downward to cut the excess copper wires of the two wires.

[0045] The terminal is made to enter the first positioning groove 14, and the first positioning groove 14 continues to move downward. The first positioning block 9 cooperates with the forming die 35. At the same time, the first matching block 13 drives the first ejector blade 12 to rotate along the hinge point to cut the waste wires placed at the M-shaped forming opening.

[0046] The first positioning block 9 compresses the first return spring 10, and the driving block 3 drives the first forming block 11 to move downward, bringing the terminal in the first positioning groove 14 to the M-shaped forming opening for extrusion and forming.

[0047] After extrusion is completed, the driving motor 2 drives the first positioning block 9 to move upward, and the first forming block 11 moves upward. After the first compression spring 10 is reset, the first positioning block 9 also moves upward. The terminal feeding assembly drives the terminal to move to the working station. At the same time, the first fitting block 13 drives the first unloading knife 12 to move upward. Since the crimped end will deform, a part of the terminal is exposed outside the M-shaped forming port. The first unloading knife 12 drives the crimped finished product to be lifted from the M-shaped forming port, and the product processing is completed.
