To complete processing tasks.Its winding method, which is divided into, core coiling and the class of centreless coiling two.There is core coiling to be divided into craft and lathe again
Two kinds of forms of coiling.And the ratio between the internal diameter of spring and steel wire diameter, i.e. spring wrap ratio, it is the decision for determining spring Coil-up difficulty
Factor.Winding is than smaller, and spring wire diameter and spring inside diameter are closer, and spring Coil-up deformation drag is bigger, and shaping is more difficult；
When being especially wound around than less than 1, it will be unable to process using lathe centreless winding method, the method that core coiling can only be taken.But
That because winding is than being less than 1, that is, spring wire diameter is more than coiling diameter of mandrel, because plug insufficient rigidity less than normal without
Lathe coiling can be used, can only be made by hand by pincers worker, and manual processing is not high with conventional method qualification rate and yield.

Point and jaw contacts, remainder are hanging, and fixed point free supporting, processing plug is too thin, when causing steel wire winding spring body by
Force deformation is bent；
2. pitch is uneven
Process in part it is seen that shaping the effectively fixed machining control of neither one in whole process to pitch
Means, controlled entirely with operator with experience gimmick during winding, last size solves by correction, if error is too big during processing
It will be unable to correct.
3. external diameter is overproof
Main cause is corrected pitch, caused by spring body diameter stress deformation, causes spring body diameter overproof.
4. surface tear
Reason is simpler, caused by tapping wound caused by when correcting spring linearity and pitch.Also tried with than bullet in processing
The material of spring material softer corrects as backing plate, but is unable to reach requirement.Also needed to use two to three pieces with one spring of steel plate correction
Slab, and steel plate damage can not recycle again, so unworkable with softer material bearing calibration.
Through analysis, each problem of the above all produces in process.Process is that wire clip is used into plug on vice
Turning handle steel wire winding is on plug.Because without fixing point, steel wire winding originally ten on the smaller plug of diameter
Divide difficulty, then to ensure that the linearity of spring and pitch can not just be realized at all.Again to straight after only on steel wire winding plug
Dimension and pitch take the method for manual correction to can be only achieved drawing requirement.
