Specifically, referring to fig. 3, the diameter d of the arc groove is larger than the diameter of the cable 4, and the distance a between the center of the arc groove and the edges of the upper die 11 and the lower die 12 is 4mm to 5 mm.

It should be noted that, the diameter d of the arc groove is set to be larger than the diameter of the cable 4, and the center of the arc groove and the side distance a between the upper die 11 and the lower die 12 are set to be 4mm to 5mm, so that the cable 4 can be placed in the arc groove, and then the cable 4 is clamped, so that the cable 4 is bent into a required shape.

Further, referring to fig. 4, the cable continuous bending apparatus further includes: a holder 5;

the retainer 5 is arranged at the outlet of the bending die and used for clamping the bent cable.

s2, controlling the upper die and the lower die to convey the cable to a target position along the cable output direction;

s3, controlling the upper die and the lower die to loosen the cable at the target position;

and S4, controlling the upper die and the lower die to return to the clamping position, and executing S1 again.

The cable straightening device comprises an upper die, a lower die, a cable clamp and a cable clamp, wherein the upper die and the lower die are arranged on the upper die; then, the upper die and the lower die are controlled to convey the cable to a target position along the cable output direction; and the upper die and the lower die are controlled to loosen the cable at the target position, finally the upper die and the lower die are controlled to return to the clamping position to clamp the straightened cable again, and the actions are repeated to finish continuous bending of the cable.

and in the clamping position, the upper die is controlled to move downwards, so that the upper die and the lower die are matched to clamp the cable.

S402, the limit sensor sends a stop signal to the power assembly.

When the upper die moves downwards at the clamping position, whether the upper die moves to a preset point is detected in real time through a limit sensor; when the limiting sensor detects that the upper die moves to a preset point, the limiting sensor sends a stop signal to the power assembly, the power assembly stops driving the upper die to move downwards, a certain gap (namely, a clamping interval) exists between the upper die and the lower die, the upper die can be prevented from moving downwards to be in contact with the lower die, and when the upper die and the lower die convey cables, the problem that the cables are damaged due to the fact that the cables are subjected to too large extrusion force is effectively avoided.

Further, after the step S3 is executed, the method further includes the following steps:

and controlling the clamping frame to clamp the bent cable.
