A first screw extending in the left and right direction is arranged on the upper part of the frame. The right end of the screw rod is power-coupled with the first driving motor, and a second screw rod extending in the left-right direction is arranged at the bottom of the frame, and the left end of the second screw rod is power-connected with the second driving motor, wherein the left sliding forming die The upper part is provided with a left optical hole, the lower part is provided with a left screw hole, the upper part of the right sliding forming mold is provided with a right screw hole, and the lower part is provided with a right optical hole, wherein the first screw is slidably matched with the left optical hole, and The right screw hole is threadedly matched, the second screw rod is threadedly fitted with the left screw hole, and is slidably matched with the right light hole.

According to another aspect of the present invention, a method for bending and forming the head of a cable, using the above-mentioned bending device, includes the following steps: firstly, passing the head of the cable through the pair of upper guide rollers and the distance between the lower guide roller pair, the first driving motor and the second driving motor operate so that the left sliding forming die and the right sliding forming die move toward each other to clamp the cable; then, the The operation of the first driving motor and the second driving motor makes the left sliding forming die and the right sliding forming die move in the same direction, and under the cooperation of the upper pair of guide rollers and the lower pair of guide rollers, the cable The head is bent and shaped; finally, the first drive motor and the second drive motor operate so that the left and right slide forming dies move away from each other to loosen the cable.

Through the present invention, due to the use of two cylindrical forming dies, the bottom of each forming die is provided with two moving rollers, and under the action of the driving force, the moving rollers can drive the two forming dies on the left and right sides of the frame. It moves in two directions, so it is possible to process the head of the cable with multiple openings facing different U shapes to meet the requirements for multiple fixing of the cable, or it can also process multiple openings facing the same U shape, or a combination thereof. Moreover, by combining each forming die with two screw thread fits and sliding fits, the tendency of the forming die to rotate can be resisted, and it can be used as a screw drive for another forming die at the same time, thus saving equipment space and reducing costs. Since each forming die is controlled by a separate screw, it can perform clamping operation, bending operation, and loosening operation. Therefore, the above three operations are realized with only two screws and no guide rods, maximizing The equipment structure is simplified under the condition of ensuring the use requirements. Moreover, through the adjustable guide rollers, it can meet the bending of cables with different diameters, and can ensure the shape accuracy of its U-shaped bent horizontal legs, avoiding an inclined shape. This mode of bending enables the exact spot where it needs to be bent, avoiding wasted cables.
