The right end of the screw rod is power-coupled with the first drive 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 drive motor, and the first drive motor and the The outer surface of the second driving motor is provided with a cooling water pipe, and the cold water in the cooling water pipe can absorb and dissipate the heat generated during the operation of the first driving motor and the second driving motor to prevent the temperature from being too high And damage, wherein, the upper part of the left sliding forming die is provided with a left light hole, the lower part is provided with a left screw hole, the upper part of the right sliding forming die is provided with a right screw hole, and the lower part is provided with a right light hole, wherein, the first A screw rod is slidably engaged with the left optical hole, and threadedly engaged with the right screw hole, and the second screw rod is threadedly engaged with the left screw hole, and is slidably engaged with the right optical 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 gap 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, under the action of driving force, the two cylindrical forming dies can slide in the guide chute along the left and right directions, so the head of the cable can be A plurality of U-shapes with different openings are processed to meet the requirements for multiple fixation of cables, and a plurality of U-shapes with the same openings may also be processed, 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. By setting cooling water pipes on the outer surface of the driving motor, the cold water flowing in the cooling water pipes can absorb and take away the heat generated when the first driving motor and the second driving motor are running, preventing the driving motor from driving for a long time After operation, the temperature is too high and damaged, so as to ensure the normal operation of the bending equipment.
