Ribbon cable usually refers to parallel multi-core wires in strip shape, such as gray cable, rainbow cable, high temperature cable, etc. Its processing technology generally adopts multiple wire cores arranged at equal intervals. In this process, it is generally necessary to pull multiple wire cores to make them stretch appropriately, so as to facilitate the subsequent hot pressing and other operations.
[0003] Existing stretching devices usually insert the wire cores one by one into the clamp holes, and then the clamps at both ends are stretched in the slide slot to complete the stretching step. However, the wire cores of the ribbon cable vary according to the actual needs.

The core pulling and stretching device for processing a ribbon cable according to claim 8, characterized in that: The second limiting slider (242) is slidably connected in the second slide groove (112), the transverse support block (241) is fixedly connected to one end of the fixed clamp (21), and the third limiting slider (247) is slidably connected in the fourth slide groove (1143).
10. A method for using a core pulling and stretching device for processing a ribbon cable, comprising a core pulling and stretching device for processing a ribbon cable according to any one of claims 1 to 9, characterized in that ； Step 1: feeding and clamping the wire core: the wire core in the wire coil enters the fixed chuck (21) from between the two sets of friction wheels (212) and is clamped by the movable chuck (23). Then, the movable chuck (23) moves under the drive of the stretching assembly (13). When the wire core is pulled to the specified processing size by the movable chuck (23), the fixed chuck (21) clamps the wire core. Then, the cutter head (215) cuts the wire core under the push of the small propulsion cylinder (216) to complete the feeding. Step 2, determining the wire core spacing: after the fixed chuck (21) is clamped, the telescopic cylinder (116) installed on the front plate (11) drives the displacement support rod (114) to move upward, so that the displacement support rod (114) drives the gap control component (24) to move, and then the spacing between the two sets of fixed chucks (21) is determined to a desired size and fixed; Step 3: Complete stretching: The stretching assembly (13) drives the wire core at one end of the movable clamp (23) to slowly stretch the wire core to complete the traction and stretching process of the wire core.
