[0037] When the terminal passes through the feed tube 2 and the terminal is pressed on the outer wall of the control box 5, the terminal pushes the control box 5 and the second slider 36 to move, the compression spring 39 is in a compressed state, and the control box 5 drives the pressing column 42 and the support column 40 to move synchronously, the pressing column 42 presses on the contact switch 43, and at the same time, the end of the support column 40 presses on the fixed column 41, the control box 5 stops moving, and the contact switch 43 controls the hydraulic telescopic rod 19 to start, so that the two crimping dies 6 can be moved closer to each other. When the crimping is completed, the two crimping dies 6 located at the crimping station are reset to the initial position, and the staff drives the terminal to be pulled out of the terminal crimping box 1. The compression spring 39 pushes the second slider 36 and the control box 5 to reset to the initial position, and the pressing column 42 no longer presses the contact switch 43.

[0038] Working principle: During operation, the rotating frame 4 is driven to rotate by adjusting the locking piece, and the rotating frame 4 drives the control box 5 and the crimping die 6 to rotate, so that the two crimping dies 6 to be used are rotated to the crimping station. When the positions of the rotating frame 4 and the crimping die 6 are adjusted, the rotating frame 4 at the adjusted position is locked and fixed by adjusting the locking piece. The staff inserts the terminal with the cable into the terminal crimping box 1 through the feeding tube 2. The terminal abuts against the outer wall of the control box 5, and the control box 5 moves. The elastic support counting mechanism elastically supports the terminal. The two crimping dies 6 located at the crimping station are respectively located above and below the terminal. The two crimping dies 6 located at the crimping station are driven to rotate by the pressing structure. The two crimping dies 6 are moved closer to each other, and the terminals are crimped by the two crimping dies 6. When the crimping is completed, the pressing structure no longer applies pressure to the crimping dies 6, and the elastic reset member drives the two crimping dies 6 to reset to the initial position. The staff member draws the crimped terminals out of the terminal crimping box 1, and the elastic support counting mechanism drives the control box 5 to reset to the initial position relative to the rotating frame 4, and counts the number of times the control box 5 moves. According to actual needs, crimping dies 6 of different specifications can be switched to facilitate crimping the terminals into specified shapes. At the same time, the number of times the crimping dies 6 are used can be counted, and the service life of the crimping dies 6 can be understood in real time to avoid batches of defective products and take preventive measures.

[0039] When the pressing structure drives the two crimping dies 6 located at the crimping station to move closer, the crimping dies 6 drive the mounting block 7 and the movable seat 8 to move through the first slider 22, and the two movable seats 8 move closer, and the first tension spring 10 is in a stretched state. When the pressing structure no longer applies pressure to the crimping die 6, the first tension spring 10 drives the movable seat 8 to move in the opposite direction to the initial position, so that the crimping die 6 can be reset to the initial position relative to the control box 5. When the service life of the crimping die 6 is reached, the position of the rotating frame 4 is adjusted by adjusting the locking piece, and the rotating frame 4 drives the control box 5 to rotate, so that the two crimping dies 6 that have reached their service life move to the disassembly and assembly station, and the two crimping dies 6 located at the disassembly and assembly station are located on one side of the disassembly and assembly hole 3. At the same time, the four movable blocks 27 located at the disassembly and assembly station move to the preset position, and the movable frame 29 slides into the corresponding second slide groove 30, and the second rotating shaft 32 and the worm 34 are driven to rotate by the motor 33, and the worm 34 drives the two bidirectional screw rods through the worm gear 35 31 rotates synchronously, and the bidirectional screw rod 31 can drive the two movable frames 29 to move away from each other, so that the movable frame 29 pushes the movable block 27 and the prism 25 to slide relative to the mounting block 7, and the second tension spring 28 is in a tensioned state. When the end of the prism 25 disengages from the corresponding limiting groove 24, the limitation on the position of the first slider 22 is released, and the motor 33 is turned off. The staff drives the crimping mold 6 to move, and the first slider 22 disengages from the first slide groove 23 until the crimping mold 6 is pulled out of the terminal crimping box 1 through the disassembly hole 3. Similarly, the staff puts two new crimping molds 6 into the terminal crimping box 1 through the disassembly hole 3, and the first slider 22 on the crimping mold 6 slides into the first slide groove 23, and the second rotating shaft 32 is driven by the motor 33 to rotate in the opposite direction, so that the movable frame 29 is reset to the initial height, and the second tension spring 28 drives the movable block 27 and the prism 25 to move to the initial height, and the end of the prism 25 is inserted into the corresponding limiting groove 24 again, and the disassembly and assembly of the crimping mold 6 can be completed.

[0040] When it is necessary to press the two crimping dies 6 located at the crimping station, the movable plate 20 and the toothed plate 21 are driven to move by the hydraulic telescopic rod 19, and the toothed plate 21 drives the connecting shaft 15 and the second damping plate 16 to rotate through the gear 18, and the second damping plate 16 drives the first damping plate 14, the first rotating shaft 11 and the cam 12 to rotate through the friction force, and the cam 12 can push the two crimping dies 6 located at the crimping station to move closer, and when the two crimping dies 6 are closed together, the terminals are crimped by the two crimping dies 6, and with the continuous movement of the movable plate 20 and the toothed plate 21, the second damping plate 16 cannot drive the first damping plate 14, the first rotating shaft 11 and the cam 12 through the friction force. The damping disc 14 and the first rotating shaft 11 rotate to ensure that the first rotating shaft 11 and the cam 12 automatically stop after rotating to the preset position. When the crimping is completed, the movable plate 20 is driven to rotate in the opposite direction by the hydraulic telescopic rod 19, and the second damping disc 16 can drive the first damping disc 14 to rotate in the opposite direction by friction. The cam 12 no longer applies pressure to the crimping die 6. When the cam 12 contacts the stop block 52, the cam 12 is reset to the initial position. As the hydraulic telescopic rod 19 drives the movable plate 20 to continue to move, the second damping disc 16 is no longer able to drive the first damping disc 14 to rotate synchronously by friction, ensuring that the cam 12 automatically stops after resetting to the initial position.

[0041] When the terminal passes through the feed tube 2 and the terminal is pressed on the outer wall of the control box 5, the terminal pushes the control box 5 and the second slider 36 to move, the compression spring 39 is in a compressed state, and the control box 5 drives the pressing column 42 and the support column 40 to move synchronously, the pressing column 42 presses on the contact switch 43, and at the same time, the end of the support column 40 presses on the fixed column 41, the control box 5 stops moving, and the contact switch 43 controls the hydraulic telescopic rod 19 to start, so that the two crimping dies 6 can be moved closer to each other. When the crimping is completed, the two crimping dies 6 located at the crimping station are reset to the initial position, and the staff drives the terminal to be pulled out of the terminal crimping box 1. The compression spring 39 pushes the second slider 36 and the control box 5 to reset to the initial position, and the pressing column 42 no longer presses the contact switch 43. The information of the RFID tag 45 is read by the RFID reader 44, and it can be known that The two crimping dies 6 on which control box 5 are working, and the service life of the crimping dies 6 can be timely understood according to the number of times the contact switch 43 is pressed; the staff drives the top plate 48 to move upward, the bottom end of the positioning column 49 disengages from the corresponding positioning sleeve 51, and the third tension spring 50 is in a stretched state. The staff drives the top plate 48 to rotate, and the top plate 48 drives the third rotating shaft 46 and the rotating frame 4 to rotate through the positioning column 49 and the fixing seat 47. When the rotating frame 4 does not need to rotate, the staff releases the top plate 48, and the third tension spring 50 drives the top plate 48 and the positioning column 49 to move downward, and the bottom end of the positioning column 49 is inserted into the corresponding positioning sleeve 51, and the positioning column 49 and the fixing seat 47 no longer rotate relative to the positioning sleeve 51 and the terminal crimping box 1, so that the rotating frame 4 and the third rotating shaft 46 adjusted in position can be fixed to complete the adjustment of the position of the rotating frame 4.
