One end of the second cylinder 10 is fixedly connected with a concave moving block 11. A flexible clamping plate 12 is slidably connected to an inner wall of the concave moving block 11. A right side of the flexible clamping plate 12 is fixedly connected with a moving inclined plate 13. The outside of the moving inclined plate 13 penetrates through the concave moving block 11. A front right side of the top end of the bottom plate 1 is fixedly connected with a fixed inclined block 14. A front side of the die bottom plate 8 is fixedly connected with a fixed triangular block 15. A concave opening 20 is formed in a middle of the top end of the bottom plate 1. A telescopic assembly is arranged at a bottom of an inner wall of the concave opening 20. A triangular groove 17 is formed in a rear side of the concave moving block 11. A winding mechanism 2 is arranged at a right side of the top of the bottom plate 1. The winding mechanism 2 is used for winding the waste of the terminal;

[0033] Specifically, place the wire to be processed inside the concave moving block 11, and press the front side of the wire against the front side of the moving triangular block 16. Then start the second cylinder 10 to drive the concave moving block 11 to move backward along the bottom plate 1. At the same time, the moving triangular block 16 can be pushed to move backward along the bottom plate 1 together. At this time, the moving triangular block 16 contacts the inclined surface of the fixed triangular block 15. At this time, the moving triangular block 16 will move downward along the bottom plate 1 until the concave moving block 11 contacts the die bottom plate 8. At this time, the triangular groove 17 is engaged with the fixed triangular block 15, and the wire will be inserted into the terminal. Then start the first cylinder 4 to drive the block cylinder 5 and the pressing block 7 to press the wire and the terminal, so as to complete the crimping. Then contract the first cylinder 4 and the second cylinder 10 to reset, and the moving triangular block 16 is reset under the action of the spring 18.

[0035] Specifically, during the process of crimping the wire, the waste generated by the terminal will accumulate on the side, and the waste is wound above the winding wheel 206. When the winding wheel 206 winds too much waste, the rotating block 205 is rotated at this time to release the engagement with the fixed column 204, and then the pressing plate 202 is opened, and the winding wheel 206 is taken out to complete the cleaning of the waste. After cleaning the waste, it is completed according to the original.

[0036] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in FIGS. and, the telescopic assembly includes a moving plate 19 which is slidably connected to the bottom of the inner wall of the notch 20. A spring 18 is fixedly connected to the top of the moving plate 19, and a moving triangular block 16 is fixedly connected to the top of the spring 18. L-shaped fixing plates 21 are fixedly connected to both the left and right sides of the mold bottom plate 8. A plurality of fixing screws 22 are provided at the top ends of the L-shaped fixing plates 21. The outer wall of the fixing screw 22 penetrates through the L-shaped fixing plate 21 and is threadedly connected to the bottom plate 1. An inclined fixing block 23 is fixedly connected to the rear side of the mold bottom plate 8, and an inclined limiting block 24 is fixedly connected to the rear side of the top end of the bottom plate 1. An L-shaped column 25 is fixedly connected to the left side of the top end of the bottom plate 1. A feeding disc 26 is rotatably connected to the top of the outer wall of the L-shaped column 25. A fixing cover 27 is provided at the front side of the top end of the L-shaped column 25.

[0037] Specifically, the moving plate 19 can drive the spring 18 to move towards the rear side of the bottom plate 1. The spring 18 can facilitate the reset of the moving triangular block 16. The L-shaped fixing plate 21 and the fixing screw 22 can facilitate the fixing of the mold bottom plate 8. The mold bottom plate 8 can be restricted from moving by the engagement of the inclined limiting block 24 and the inclined fixing block 23. The L-shaped column 25 can support the feeding disc 26, and it can be fixed by the fixing cover 27.

[0038] Refer to Figure 1 and Figure 2 As shown in FIGS. and, a limiting rod 28 is fixedly connected to the front right side of the top end of the bottom plate 1, and a lighting lamp 29 is fixedly connected to the left side of the limiting rod 28. Limiting columns 30 are fixedly connected to both the front and rear sides of the top end of the moving plate 19, and the outer sides of the limiting columns 30 penetrate through the moving triangular block 16. An alarm 31 is fixedly connected to the rear right side of the top end of the bottom plate 1. Chute grooves 32 are opened on both the left and right sides of the inner wall of the upper mold block 6, and the pressing blocks 7 are slidably connected to the chute grooves 32.

[0039] Specifically, the limiting rod 28 can support the lighting lamp 29. The lighting lamp 29 can provide brightness. The limiting columns 30 can limit the moving direction of the moving triangular block 16. The alarm 31 can remind the staff when a failure occurs. The chute grooves 32 can facilitate the movement of the pressing blocks 7.

[0040] Working principle: Before using this device, first, place the wire to be processed inside the concave moving block 11 and ensure that the front end of the wire is closely attached to the front side of the moving triangular block 16. Subsequently, activate the second cylinder 10 to drive the concave moving block 11 to drive the moving triangular block 16 to move together towards the rear side of the bottom plate 1. At this time, the inclined surface of the moving triangular block 16 comes into contact with the inclined surface of the fixed triangular block 15, thereby causing the moving triangular block 16 to move towards the bottom of the bottom plate 1 until the concave moving block 11 is in close contact with the mold bottom plate 8. Moreover, the triangular groove 17 on the moving triangular block 16 forms an engaging state with the fixed triangular block 15. At this time, the wire is inserted into the terminal. Next, start the first cylinder 4 to push the block cylinder 5 and the pressing block 7 to apply pressure to the joint of the wire and the terminal to complete the crimping operation. After the crimping is completed, sequentially contract the first cylinder 4 and the second cylinder 10 to restore each component to its initial position. During this process, the moving triangular block 16 automatically resets under the elastic force of the spring 18. And through the winding mechanism 2, during the wire crimping operation, the waste generated by the terminal will accumulate on the side, and this waste is wound around the winding wheel 206. When the waste wound on the winding wheel 206 reaches a certain degree, unlock the locking state between it and the fixed column 204 by rotating the locking block 205. Subsequently, open the pressing plate 202 and take out the winding wheel 206 to facilitate the cleaning of the waste. After completing the waste cleaning, just reinstall the winding wheel 206 according to the original steps and ensure that each component returns to the initial state.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
