Description
Technical field
The present invention relates to a kind of control mechanism of the constant tension in Wire EDM field, specifically a kind of wire electric discharges
The motor spring wire feeder of cutting.
Background technique
To-and-fro thread feed electric spark wire-electrode cutting machine is commonly called as " fast wire winding " lathe, has been developed for many years in China.Fast wire winding machine
Bed is distinct in terms of electrode material, working method and wire transporting with slow wire feeding lathe.Due to the wire electrode of fast wire winding
It is quickly to be moved repeatedly with higher speed, therefore fixing Methods in WEDM-HS is difficult on the constant tensile control of wire electrode relative to slow wire feeding
Du Genggao.The main reason for to-and-fro thread feed electric spark wire-electrode cutting machine top electrode thread tension changes has: reversing impact is hurried up
When silk thread cutting processing, wire electrode is to move back and forth, be recycled.In commutation, wire electrode is stopped rapidly by high-speed motion
And counter motion, biggish acceleration is generated, the presence of acceleration can generate inertia force on wire electrode, and then cause wire electrode
The variation of tension；The loss of wire electrode, during Wire-cut Electrical Discharge Machining constantly with the extension wire electrode of process time
Loss, diameter will reduce over time, and since the diameter of wire electrode reduces, the wire electrode length being wound on wire storage cylinder subtracts
It is small, so that the wire electrode length on lathe coil holder increases, so as to cause wire electrode tension reduction；The elastic-plastic deformation of wire electrode,
Elastic-plastic deformation can occur under tension for wire electrode, make wire electrode elongation to make the tension on wire electrode reduce.
Now on to-and-fro thread wire cutting machine tool the most common governing mechanism of tension be Weight type tension-adjusting gear and
