Description
Technical field
the utility model relates to a kind of Wire-cut Electrical Discharge Machining technology, especially the service life of bearing is extended in Wire-cut Electrical Discharge Machining, improve the stability into electricity, reduce electronic wire loss, improve the guide wheel assembly of working (machining) efficiency, specifically the multistage waterproof of a kind of high speed to-and-fro thread feed electric spark wire-electrode cutting machine enters conductance wheel assembly.
Background technology
As everyone knows, high speed to-and-fro thread feed electric spark wire-electrode cutting machine is in process, and electricity-supply device enters the discharge condition that electric stability drastically influence wire electrode, and the discharge condition of wire electrode drastically influence lathe cutting processing performance.In existing electricity-supply device general adopt asynchronous enter electric mode, namely electricity-supplying piece contacts with wire electrode at a place in wire transporting path, and electricity-supplying piece place received by external power source, is then delivered on wire electrode by electricity-supplying piece.When lathe cutting processing enters electricity, wire electrode and electricity-supplying piece have a relative motion.
In asynchronous system electricity-supply device, owing to there is the relative motion of a speed up to lOm/s between wire electrode and electricity-supplying piece, very easily cause the wearing and tearing of wire electrode and electricity-supplying piece.Because the wire electrode deformation angle be pressed in above electricity-supplying piece is less, cause the active force between wire electrode and electricity-supplying piece less, thus make the binding force of electricity-supplying piece to wire electrode more weak, the moment of rough wire electrode process on conducting block itself is made to produce vibration, form non-abundant contact or noncontact, its impedance is not suitable for more greatly big current cutting, thus the stability affected into electricity and working (machining) efficiency.Especially oxidizable for some and the material (such as aluminium) that the electric conductivity of its oxide is poor, hardness is higher, the some shortcomings part of such electricity-supply device exposes more obvious.When cutting processing aluminium, pure aluminum is oxidized in discharge process, its oxide portions sticks on wire electrode, when the segment electrode silk with aluminium oxide above electricity-supplying piece through out-of-date, except above-mentioned uneven and vibration, the characteristic of the poorly conductive of aluminium oxide also can affect the contact quality of segment electrode silk and electricity-supplying piece, the characteristic that the hardness of simultaneous oxidation aluminium is higher can aggravate again the wearing and tearing of electricity-supplying piece, and the wearing and tearing of electricity-supplying piece can affect the deformation angle of segment electrode silk, so when processing this kind of material, phenomenon of seeing that electricity-supplying piece has " spark ", its consequence is exactly that electricity-supplying piece is gone out groove by " processing ".The stability that above-mentioned factor will have a strong impact on into electricity, thus affect the discharge condition of wire electrode, affect the service life of electricity-supplying piece.
Simultaneously, guide wheel assembly in high speed to-and-fro thread feed electric spark wire-electrode cutting machine is the critical component that maintenance electrode silk spatial position precision requires, affect lathe cutting processing performance, and the service life how extending guide wheel assembly middle (center) bearing is also a crucial problem.
Electric spark linear cutting machine in use, molybdenum filament operates up and down in the intercropping of guide wheel, high-frequency discharge is carried out to processing work, molybdenum filament must cool again simultaneously under sufficient working solution environment, a large amount of micron-sized metal ablation product particles will be produced after electric discharge in process, and be suspended in working solution, if guide wheel assembly can not be accomplished the good protective action of working solution, metal ablation product particles will enter in the bearing of guide wheel inside with working solution, because electric discharge removal product has very high hardness, and in process, bearing is doing High Rotation Speed (about 6000 ~ 8000rpm), therefore bearing is by very quick-wearing in the metal etched matter being similar to abrasive material, thus the axial float of guide wheel and circular runout are strengthened, greatly reduce the precision and stability of wire electrode locus.The precision stability at present repeatedly with the high speed to-and-fro thread feed electric spark wire-electrode cutting machine (being commonly called as in the industry " middle wire ") of cutting function is lower, with guide wheel because be closely-related to the reduction of wire electrode positioning precision after bearing wear.And the guide wheel assembly structure (as shown in Figure 1) used at present is in cutting process, the ablation product in working solution taps into along with the straight wall of working solution along guide wheel in the bearing of component internal, thus greatly reduces the service life of bearing.Though have in assembly by wheel stand increasing the mode of bulge loop to stop that working solution enters the design of guide wheel assembly for this reason, owing to stopping the limited efficiency of working solution, the raising for bearing life is still not remarkable.
