Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing equipment, specifically a high-efficiency wire stripping and twisting machine. Background Technology

[0002] In the current cable processing field, wire stripping and twisting are usually performed using separate equipment:

[0003] In the wire stripping process, traditional wire stripping machines rely on manual feeding, which can cause the conductor to shift during blade cutting, resulting in insulation residue or damage to the wire core (especially multi-strand fine filament bundles). Although there are attempts to improve this by using guiding mechanisms, they lack axial coordination with the twisting process, requiring repositioning after stripping.

[0004] The twisting process – conventional twisting machines use pneumatic clamps to hold the conductor, but the clamping force is prone to fluctuations, and the conductor swings during high-speed rotation, causing uneven twisting. Furthermore, the stripped conductor needs to be manually transferred to the twisting station, which is inefficient.

[0005] Therefore, there is an urgent need for a high-efficiency wire stripping and twisting machine with high positioning accuracy that can simultaneously strip and twist wires, thereby improving the efficiency and processing accuracy of wire stripping and twisting. Utility Model Content

[0025] This utility model embodiment provides a high-efficiency wire stripping and twisting machine, such as Figure 1-4 As shown, it includes a workbench 11, a twisting base 12, a stripping base 13, a first electric telescopic rod 14, a rotating base 15, a twisting claw disc 16, a first slot 17, a first sliding block 18, a first opening 19, a second opening 20, a second slot 21, a second electric telescopic rod 22, a second sliding block 23, a third opening 24, a blade 25, a guide base 26, a third slot 27, a guide shaft 28, a guide roller 29, and a limiting groove 30.

[0026] like Figure 1-4 As shown, a twisting base 12 and a stripping base 13 are fixedly connected to the workbench 11. A twisting assembly is fixedly connected to the twisting base 12, and a stripping assembly is provided on the stripping base 13. The twisting assembly includes a first electric telescopic rod 14, a rotating base 15, and a twisting claw disk 16. One end of the rotating base 15 is fixedly connected to the first electric telescopic rod 14, and the other end of the rotating base 15 is fixedly connected to the twisting claw disk 16. The end face of the first electric telescopic rod 14 away from the rotating base 15 is fixedly connected to the twisting base 12. A plurality of first openings 19 are provided on the end face of the twisting claw disk 16 away from the rotating base 15.

[0027] A first slot 17 is provided on the outer circular surface of the twisting claw disk 16. Several first sliding blocks 18 are slidably connected in the first slot 17. A first opening 19 is connected to the first slot 17. Several second slots 21 are provided on the side of the first slot 17 away from the first opening 19. A second electric telescopic rod 22 is provided in the second slot 21. One end of the second electric telescopic rod 22 is fixedly connected to one end wall of the second slot 21. The other end of the second electric telescopic rod 22 is fixedly connected to a second sliding block 23. The second sliding block 23 is fixedly connected to the first sliding block 18. A second opening 20 is provided in the upper part of the first sliding block 18.

[0028] When the second sliding block 23 is located at one end of the second slot 21 near the outer circular surface of the twisted claw disk 16, the second opening 20 is coaxial with the first opening 19.

[0029] When the conductor wire bundle enters the second opening 20, the second electric telescopic rod 22 retracts, pulling the second sliding block 23 to slide towards the axis of the twisting claw disk 16. The second sliding block 23 drives the first sliding block 18 to slide towards the axis of the twisting claw disk 16, thereby clamping the conductor wire bundle through the second opening 20 and the first opening 19.

[0030] The wire stripping assembly includes several blades 25 and several guide bases 26. Several third openings 24 are provided on the wire stripping base 13. The blades 25 are fixedly connected to the outer circular surface of the third openings 24. The guide bases 26 are fixedly connected to the side of the wire stripping base 13 away from the twisting claw disk 16. A third slot 27 is provided at the end of the guide base 26 away from the wire stripping base 13. A guide shaft 28 is rotatably connected in the third slot 27. A guide roller 29 is fixedly sleeved on the outer circular surface of the guide shaft 28.

[0031] A limiting groove 30 is provided on the outer circular surface of the guide roller 29. The third opening 24 is coaxial with the first opening 19. Two blades 25 are fixedly connected to one third opening 24, and two guide bases 26 are corresponding to one third opening 24.

[0032] When this solution performs wire stripping and twisting, firstly, the conductor bundle to be processed is inserted into the third opening 24 of the stripping base 13. At this time, the limiting groove 30 on the outer surface of the guide roller 29 precisely constrains the movement trajectory of the conductor bundle, ensuring that it remains coaxial with the third opening 24 and the first opening 19, and that the first electric telescopic rod 14 is in the extended state, with the first opening 19 close to the third opening 24, thereby facilitating the entry of the conductor bundle into the first opening 19.

[0033] Next, two sets of blades 25, symmetrically mounted on the stripping base 13, are fixed along the outer surface of the third opening 24. When the conductor bundle reaches the preset stripping position, the blades 25 radially cut into the insulation layer. Due to the coaxial design of the third opening 24 and the first opening 19 of the twisting claw disk 16, the conductor bundle maintains linear motion during the cutting process. The cut insulation layer naturally separates and is peeled off by a subsequent mechanism.

[0034] Then, the stripped conductor bundle enters the second opening 20 of the twisting claw disk 16. At this time, the second electric telescopic rod 22 is in the extended state, pushing the second sliding block 23 to one end of the second slot 21 near the outer circle of the twisting claw disk 16, so that the second opening 20 is coaxial with the first opening 19, which facilitates the conductor bundle to pass through without resistance.

[0035] Subsequently, the second electric telescopic rod 22 retracts, pulling the second sliding block 23 to slide along the second slot 21 toward the axis of the twisting claw disk 16. Since the second sliding block 23 is fixedly connected to the first sliding block 18, the first sliding block 18 moves inward along the first slot 17 in sync, clamping and fixing the conductor bundle through the coordinated displacement of the second opening 20 and the first opening 19.

[0036] Finally, the first electric telescopic rod 14 retracts, thereby pulling the conductor bundle towards the twisting base 12 via the twisting claw disc 16. As the conductor bundle slides along the third opening 24, it continuously strips the wire. The rotating base 15 drives the twisting claw disc 16 to rotate, and the clamped conductor bundle twists synchronously around the axis of the twisting claw disc 16. The number of twists and the speed are precisely adjusted by the electronic control system to achieve efficient twisting.
