Abstract
The invention relates to a tension regulating mechanism for a wire electrode of an electrospark linear cutting machine, which comprises a main tension regulating device and also comprises an auxiliary tension regulating mechanism, wherein the main tension regulating device is arranged near a vertical post, and the auxiliary tension regulating mechanism is arranged at one side of a main guide wheel of an upper arm. The auxiliary tension regulating mechanism comprises an elastic element, a floating support and an auxiliary tension regulating guide wheel, wherein the auxiliary tension regulating guide wheel is arranged on the floating support; the floating support is arranged on the upper arm at one side of the main guide wheel through a plate spring; and the included angle between the connecting line of the auxiliary tension regulating guide wheel and the main guide wheel and the horizontal line is 20-85 degrees. Under the action of the tension of the wire electrode at one side of the main guide wheel, the elasticity of the elastic element is overcome by the floating support provided with the auxiliary tension regulating guide wheel, thereby, the tension of the wire electrode at one side of the main guide wheel is ensured to be always kept within a reasonable range. A double-tension regulating mechanism is adopted, and moreover, the double-tension regulating mechanism is used for putting emphasis on regulating the tension of the wire electrode at one side of the main guide wheel to always keep the tension of the wire electrode within a reasonable range, thus, the tension regulating mechanism for the wire electrode of the electrospark linear cutting machine has a simple structure, timely regulation and short retardation time.
Description
Technical field
The present invention relates to the machine tool technology field, especially a kind of Wire Electrode WEDM governing mechanism of tension.
Background technology
Present widely used to-and-fro wire-travelling type electric spark linear cutting machine; Because in continuous reciprocating motion, there is the irregular variation of tension force in wire electrode, causes work piece surface roughness and dimensional accuracy to be difficult to reach a desirable scope; For this reason; The device that is used for the tension force of control electrode silk is widely used, and like Weight type tension-adjusting gear commonly used, it utilizes the tension force of the adjusting wire electrode that is installed on the weight on the support.It is installed near the column usually, mostly near thread delivering machine structure one side.
The weak point of prior art is: because the frictional force factor of guide wheel; The tension force of the wire electrode of other part and inconsistent in the tension force of processing district wire electrode and the loop; The existing multiple wire electrode tension governor motion that comprises the Weight type tension-adjusting gear; It is regulated the effect of processing district wire electrode tension and pays no attention to; And the processing district wire electrode tension is one of factor that influences the machining accuracy most critical, the very tight and not enough situation of processing district wire electrode tension of the wire electrode pull spring that tends to occur thread delivering machine structure one side.In addition, because governing mechanism of tension exists tension adjustment the hysteresis quality on the regular hour is arranged, the tension force of processing district wire electrode is difficult to reach comparatively desirable state.
Summary of the invention
The objective of the invention is above-mentioned deficiency, a kind of Wire Electrode WEDM governing mechanism of tension that can effectively improve processing district wire electrode tension state is provided to prior art.

Above-mentioned auxiliary governing mechanism of tension is owing to be installed on upper arm capstan one side, and it can effectively improve processing district wire electrode tension state.
Further technical solution does,
Said auxiliary governing mechanism of tension comprises auxiliary tension adjustment guide wheel, bearing, flexible member float; Said auxiliary tension adjustment guide wheel is installed on the bearing that floats; The bearing that should float is installed through flexible member on the upper arm of capstan one side, and the line and the angle between the horizontal line of auxiliary tension adjustment guide wheel and capstan are 20-85
0
Wire electrode is drawn by the silk tube of thread delivering machine structure; Through some transition guide wheels and through advocating the apparatus for adjusting force adjustment of tonicity; Through auxiliary tension adjustment guide wheel, last pile warp capstan gets into the processing district, under the wire electrode tension effect of capstan one side again; The unsteady bearing of guide wheel that auxiliary tension adjustment is installed overcomes the elastic force of flexible member, thereby the wire electrode tension that guarantees capstan one side remains in the reasonable range.
This technical solution is to realize the most simply one of mode of above-mentioned technical solution.
Above-mentioned flexible member can be for leaf spring, spring, have one of metallic plate of certain flexible bending.
The present invention adopts two governing mechanism of tension; And the wire electrode tension of regulating capstan one side emphatically remains in the reasonable range; Make the wire electrode tension of capstan one side remain in the reasonable range, and regulate in time that lag time is short.Adopt the unsteady seat structure of installing through flexible member, make simple in structure.
Further technical solution is that the line and the angle between the horizontal line of said auxiliary tension adjustment guide wheel and capstan are 60-85 again
0
Above-mentioned angle approaches 90 more
0, regulating effect is good more.
Further technical solution does again
Capstan one side is equipped with auxiliary governing mechanism of tension equally under the said underarm.
The auxiliary governing mechanism of tension of capstan one side can adopt the identical structure of auxiliary governing mechanism of tension with upper arm capstan one side under the underarm.
This technical solution has been regulated the i.e. tension force of the molybdenum filament between capstan up and down in processing district better.
