[0034] In order to make the technical means, creative features, achieved purposes and functions of this utility model easy to understand, the technical solutions in the detailed implementation manners of this utility model are clearly and completely described below to further elaborate this utility model. Obviously, the described detailed implementation manners are only part of the implementation manners of this utility model, rather than all the styles.

[0035] Embodiment 1:

[0036] Please refer to Figure 1 , Figure 5 and Figure 6 , this utility model provides a technical solution: a self-feeding wire harness terminal crimping die, including an operating table 1, a processing groove 2 is opened on the operating table 1, the top of the processing groove 2 is connected with a rotating component 7 through a driving mechanism 6, and the driving mechanism 6 is driven by a punching machine (the punching machine used in the driving structure is not shown in the figure);

[0037] The rotating component 7 includes a "冂"-shaped support frame 701, a rotating shaft 702 is rotatably connected to the support frame 701, a positioning disk 703 is connected to the rotating shaft 702, the positioning disk 703 is located inside the support frame 701, and a plurality of die bodies 704 with different shapes are connected to the surface of the positioning disk 703;

[0038] A circular receiving groove 8 is provided at the bottom of the processing groove 2, and a rotatable circular rotating plate 9 is provided in the receiving groove 8. A plurality of support seats 12 of different shapes are connected to the top of the rotating plate 9, and the plurality of mold bodies 704 are respectively matched with the plurality of support seats 12 in a one-to-one correspondence;

[0039] The bottom of the processing groove 2 is connected with a sliding frame 3 , and the sliding frame 3 is located at one side of the storage groove 8 . A pushing component 13 is provided at one side of the processing groove 2 , and the pushing component 13 cooperates with the sliding frame 3 .

[0040] Specifically, one end of the rotating shaft 702 is connected to a rotating frame 705, and the rotating frame 705 is located on one side of the supporting frame 701. The other end of the rotating shaft 702 is connected to a diamond block 706. A diamond groove 707 is provided on the other side of the supporting frame 701. The diamond block 706 cooperates with the diamond groove 707. The other side of the supporting frame 701 is connected to a protective shell 708. A first spring 709 is arranged between the other side of the diamond block 706 and the inner wall of the protective shell 708.

[0041] By adopting the above technical solution, the rotating shaft 702 is conveniently pushed through the rotating frame 705, the diamond block 706, and the diamond groove 707, thereby rotating the positioning plate 703 and adjusting the mold body 704. Due to the special shape design of the diamond block 706 and the diamond groove 707, when the diamond block 706 is fully embedded in the diamond groove 707, the mold body 704 below the positioning plate 703 is aligned with the support seat 12 below. Through the first spring 709, a thrust is applied to the diamond block 706 during crimping to prevent the diamond block 706 from moving out of the diamond groove 707, thereby causing the rotating shaft 702 to rotate.

[0042] Specifically, a terminal strip 4 is placed in the sliding frame 3, an adjustment slot 5 is provided at the top of the sliding frame 3, and the pushing assembly 13 includes a fixed frame 131, which is connected to one side of the processing slot 2, and a "factory"-shaped support plate 132 that can move left and right is provided in the fixed frame 131, and a rotatable "L"-shaped baffle 135 is provided at the bottom of the support plate 132, and an electric push rod 133 is connected to one side of the fixed frame 131, and an output end of the electric push rod 133 is connected to one side of the support plate 132, and a fixed seat 134 is connected to the bottom of the support plate 132, and the baffle 135 is rotatably connected to the fixed seat 134, and a second spring 137 is provided between the top of the baffle 135 and the support plate 132, and a baffle 136 is connected to the bottom of the baffle 135, and the baffle 136 passes through the adjustment slot 5 to cooperate with the terminal strip 4 placed on the sliding frame 3.

[0043] By adopting the above technical solution, the terminal strip 4 can be easily driven to move intermittently through the support plate 132, the stop rod 135, the electric push rod 133 and the stop block 136, so that it is convenient for the staff to put in the wire harness for crimping operation.

[0044] Embodiment 2:

[0045] Based on Example 1, please refer to Figure 2 , Figure 3 and Figure 4 .

[0046] Specifically, four limit blocks 11 are connected to the surface of the rotating plate 9, four limit grooves 10 are opened on the side of the storage groove 8, and the four limit blocks 11 are respectively matched with the four limit grooves 10. A blowing nozzle 14 is connected to one side of the processing groove 2, and the blowing nozzle 14 and the supporting seat 12 are in the same plane. A placement groove 15 is opened on the back of the operating table 1, and a high-pressure air pump 16 is connected to one side of the placement groove 15. The output end of the high-pressure air pump 16 is connected to a ventilation pipe 17, and the ventilation pipe 17 passes through the operating table 1 and is connected to the blowing nozzle 14.

[0047] By adopting the above technical solution, the rotating plate 9 is limited by the limit block 11 and the limit groove 10 after the support seat 12 is adjusted to prevent the support seat 12 from moving during crimping. The support seat 12 is blown and cleaned after crimping by the blowing nozzle 14, the high-pressure air pump 16 and the ventilation pipe 17 to avoid residual debris during the terminal crimping, which will affect the next terminal crimping operation.

[0048] Specifically, a snap-in groove 18 is opened on one side of the bottom of the processing groove 2, and a storage box 19 is placed in the snap-in groove 18. The storage box 19 cooperates with the blowing nozzle 14. A control module 20 is connected to one side of the operating table 1. The control module 20 is electrically connected to the driving mechanism 6, the electric push rod 133 and the high-pressure air pump 16 through wires.

[0049] By adopting the above technical solution, the blown debris can be conveniently collected through the storage box 19, so that the staff can handle it in a unified manner.

[0050] The working principle of the utility model is as follows: when in use, the staff puts the terminal strip 4 used for the wiring harness into the sliding frame 3, pushes the stopper 136, and inserts the stopper 136 between the first terminal and the second terminal on one side of the terminal strip 4. The staff pushes the rotating frame 705 to make the rotating frame 705 push the rotating shaft 702, so that the rotating disk moves in the support frame 701, so that the diamond block 706 at one end of the rotating shaft 702 moves out of the diamond groove 707, squeezes the first spring 709, and causes the first spring 709 to undergo elastic deformation. At this time, when the diamond groove 707 no longer limits the diamond block 706, the staff can twist the rotating frame 705 to make the rotating shaft 702 rotate on the support frame 701, and drive the positioning disk 703 to rotate through the rotating shaft 702, so that the crimping mold body 704 to be used can be moved to the bottom of the positioning disk 703 according to the crimping requirements;

[0051] Then, the rotating frame 705 is loosened, so that the diamond block 706 enters the diamond groove 707 for limiting due to the push of the spring. Due to the special shape of the diamond block 706 and the diamond groove 707, it can be ensured that when the mold body 704 below is not completely aligned with the support seat 12 below, the diamond block 706 cannot enter the diamond groove 707 for limiting. After the diamond block 706 enters the diamond groove 707, due to the thrust of the first spring 709, the diamond block 706 is pushed to avoid the diamond block 706 from moving out of the diamond groove 707 when the mold body 704 is in use, thereby ensuring the stability of the mold body 704 during crimping.

[0052] After the mold body 704 is adjusted, the staff can take out the rotating plate 9 from the receiving groove 8, select the support seat 12 that can match the upper mold body 704, align it with the upper mold body 704, and place the rotating plate 9 in the receiving groove 8. The four limit blocks 11 on the rotating plate 9 fall into the limit groove 10 at the same time to limit the rotating plate 9, ensuring that the support seat 12 is below the support seat 12, and cooperate with the mold body 704 for crimping operation to prevent the rotating plate 9 from rotating in the receiving groove 8 during crimping.

[0053] After the mold body 704 and the support seat 12 are adjusted, the control module 20 is powered by an external power supply, and the control module 20 controls the electric push rod 133 to shorten, driving the support plate 132 to move to the side away from the mold body 704, driving the blocking rod 135 to move, and at this time, the block 136 below the blocking rod 135 is blocked by the terminal on the terminal strip 4, driving the blocking rod 135 to rotate on the fixed seat 134, squeezing the second spring 137 to rotate the block 136 upward until the terminal can no longer block the block 136. After the block 136 crosses over a terminal, the block 136 is not blocked, and the second spring 137 pushes the blocking rod 135 to reset the block 136 below the blocking rod 135.

[0054] The electric push rod 133 is then extended, and the blocking terminal is blocked, driving the blocking rod 135 to rotate in the opposite direction on the fixed seat 134. This is because one side of the blocking rod 135 is in contact with the support plate 132 and cannot push the support plate 132. The blocking rod 135 and the support plate 132 are equivalent to a whole, so that the blocking block 136 under the blocking rod 135 cannot rotate. When the electric push rod 133 continues to extend, the terminal limit on the terminal strip 4 is used to push the terminal strip 4 through the blocking block 136, so that the terminal strip 4 moves to the position of the mold body 704, so that the terminals on the terminal strip 4 move to the top of the support seat 12. At this time, the support plate 132 also moves to the other side of the fixed frame 131 and stops moving.

[0055] When the terminal moves to the top of the support seat 12, the staff puts the wire harness at the crimping position of the terminal, controls the driving mechanism 6 to work through the control module 20, drives the rotating assembly 7 to descend, and the mold body 704 below descends to cooperate with the support seat 12 to crimp the terminal on the wire harness. After the crimping is completed, the electric push rod 133 repeats the above steps again, drives the subsequent terminal to move to the top of the support seat 12, and then puts in a new wire harness, so as to continue the crimping operation on the terminal;

[0056] After crimping, the control module 20 controls the high-pressure air pump 16 to operate, the high-pressure air pump 16 draws air and compresses it, and puts the compressed air into the ventilation pipe 17, and sprays it out from the blowing nozzle 14 through the ventilation pipe 17, so as to blow and clean the used support seat 12, and blow away the debris remaining after the terminal crimping to avoid it remaining on the support seat 12 and affecting the subsequent crimping. The debris is moved to the top of the storage box 19 by blowing and falls into the storage box 19, which is convenient for the staff to handle it uniformly.

[0057] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
