Embodiment 1
[0036] Embodiment 1 provides a kind of processing method of helical spring string, and it comprises the steps:
[0037] 1. A guiding steel wire is preset, and the end of the steel wire is connected with a replaceable series connection steel wire;
[0038] 2. Coil raw steel wire into coil spring;
[0039] 3. Align the front part of the inner tube of the coil spring with the head of the guiding steel wire, and cut off the steel wire at the end of the spring, let it slip and then naturally sleeve on the guiding steel wire, and then slide down to the series connecting steel wire through the guiding steel wire ;
[0040] 4. Repeat step 2) to step 3), so that the springs are sequentially set in series on the series connected steel wires to form a spring series;
[0041] 5. When the springs set on the series-connected steel wire reach the set number or the series-connected length, remove the series-connected steel wire and replace it with a new series-connected steel wire;

Embodiment 2
[0047] Embodiment 2 provides a processing method for a helical spring string, the basic steps of which are the same as in Embodiment 1, the difference being that the step 1) also includes the following steps: sequentially set the upper and lower front ends with clips manipulator; the guide steel wire is clamped on the pre-set clips at the front ends of the upper and lower manipulators;
[0048] The step 2) also includes the following steps: before the spring is rolled into shape and cut, the upper and lower manipulators move upward together with the guide steel wire clamped by them, so that the front end of the guide steel wire is aligned with the front end of the spring inner tube. Middle part; cut off the spring, so that the spring falls naturally on the guide steel wire held by the two manipulators; when the spring falls on the guide steel wire, the clip of the upper manipulator opens, and the clip of the lower manipulator does not open, so that the spring falls on the lower...
Embodiment 3
[0051] Embodiment 3 provides a processing method of a helical spring string, the basic steps of which are the same as those of Embodiment 1, the difference being that the step 1) also includes the following steps: sequentially setting the upper, middle and lower front end bands A manipulator with clips; the guide steel wire is clamped on the pre-set clips at the front end of the middle and lower manipulators;
[0052] The step 2) also includes the following steps: before the spring rolling process is completed and cut off, the upper manipulator is opened and stretched forward, and its clips clamp the spring and reset; at this time, the centers of the three manipulator clips are on a vertical line , the middle and lower manipulator clips clamp the guide steel wire; the upper manipulator clips are opened, so that the spring naturally falls on the guide steel wire clamped by the middle manipulator and the lower manipulator; when the spring falls on the guide steel wire, the middle...
