Background technology
Numerical control electric spark fixing Methods in WEDM-HS wire cutting machine tool is created for Chinese, institution of higher learning at home, and medium-sized and small enterprises are wide
General application, because its wire transporting mode is the wire transporting that moves in circles, and wire transporting speed is very fast, up to 8 ~ 10m/s, can hardly be as slow
Fast wire cutting machine is realized automatically installing wire electrode like that, and in actual production, fixing Methods in WEDM-HS wire cutting machine tool is general at present
Using manually purely manual installation wire electrode.Manually in dress silk critically important link be how wire electrode is uniform from wire tray
And be wound into having certain tensioning on wire storage cylinder, at present, this link of dress silk is primarily present problem following outstanding manually:
(1) by wire electrode at the beginning of wire tray is wound into wire storage cylinder, need first with solid silk screw, wire electrode one end to be fixed on wire storage cylinder one
End, at this time, it may be necessary to cooperation dress silk personnel apply a pretightning force and hold wire tray, is allowed to be rotated at random, not so, wire tray
On wire electrode will depart from wire tray, occur that wire electrode is loose, sleave, bending and fracture of wire phenomenon.(2) wire electrode one end is fixed
To after wire storage cylinder one end, wire storage cylinder rotates, and so that wire electrode is wound into wire storage cylinder from wire tray, needs a cooperation during this
Dress silk personnel apply a clamping force being of moderate size to wire tray, thus the wire tray to uniform rotation during winding silk applies one
Individual it is of moderate size and uniform frictional force is it is ensured that tensile force is consistent everywhere when wire electrode is wound on wire storage cylinder.Purely manual dress silk
In, typically wear gloves using dress silk personnel and apply damping force to the wire tray in uniform rotation, but so it is difficult to ensure that wire tray at the uniform velocity
In rotary course, suffered frictional force uniformly, causes tensile force size difference on wire storage cylinder for the wire electrode larger, processing
In short-circuit fracture of wire phenomenon easily occurs.In addition, if hand force is larger, the heat that friction produces is more, erosion rubber wire tray of not only burning,
Easily scald hand, and electrode thread intension power is big, easy fracture of wire;If hand force is less, electrode thread intension power is not, electric in process
Polar filament will be shaken, easily short circuit, or even fracture of wire.(3) wire storage cylinder twines Filament Winding process and terminates, when wire storage cylinder and wire tray are stopped the rotation,
There is still a need for a cooperation dress silk personnel force holds wire tray, not so the wire electrode in wire tray will occur that loose and sleave is existing
As.
Content of the invention
It is an object of the invention to:Overcome the deficiencies in the prior art, a kind of electric spark fixing Methods in WEDM-HS wire cutting machine tool is provided
Wire electrode wire tray damper, can effectively replace staff to apply the adjustable pre- clamping force of size it is ensured that manual fill to wire tray
Silk in wire electrode from wire tray be wound into wire storage cylinder beginning to terminate whole process, wire tray is all by a constant magnitude
Pretightning force, thus holding wire tray, applying one also to the wire tray of at the uniform velocity rotation in Filament Winding process and being of moderate size and uniformly rub
Power it is ensured that wire electrode equably can be wound on wire storage cylinder with the tensile force of constant magnitude, on the one hand so can avoid around
Carve at the beginning and end of silk that existing wire electrode is loose, sleave, bending and fracture of wire phenomenon;On the other hand may insure wire tray and steel wire storage
, together at the uniform velocity in rotation Filament Winding process, wire electrode can be to be of moderate size and constant tensile force is equably wound into wire storage cylinder for cylinder
On, it is to avoid wire electrode is carried out with tensioning wheel after wrapping wire occurs with tensioning again again, improves wrapping wire efficiency, people can also be avoided simultaneously
Lead to occur that frictional heat is many because exerting a force uneven during work damping, erosion rubber wire tray of burning, scald hand and process in wire electrode easy
Shake and the phenomenon such as short circuit.

When electric spark fixing Methods in WEDM-HS wire cutting machine tool needs again to be filled thread, by bolt C11, by support 2
It is fixed on electric spark fixing Methods in WEDM-HS wire cutting machine tool;Regulating bolt 5 is screwed outward, damping fin edge in the presence of spring 1
Cross bar and do and dorsad move;When the distance between damping fin is more than the width of wire electrode wire tray, wire electrode wire tray is stood
And put between damping fin and be located between silk pressing spring leaf 16, then by wire tray support bar 8 through wire electrode wire tray simultaneously
Centre bore, and wire tray support bar 8 is fixing with support 2, and by nut A9 and locking nut 12, wire electrode wire tray is carried out
Spacing;Then inwardly screwed by regulating bolt 5 again, so that damping fin is fitted with the end face of wire electrode wire tray and compress it is ensured that hindering
Enough frictional force can be produced between Buddhist nun's piece and wire electrode wire tray.
When electric spark fixing Methods in WEDM-HS wire cutting machine tool is filled thread again, first by wire electrode wire tray Top electrode silk
After one end bypasses lathe dress silk guide wheel, solid silk screw is fixed with wire storage cylinder one end, then rotates wire storage cylinder, makes in wire electrode wire tray
Wire electrode be equably wrapped in wire storage cylinder last layer.It is fixed to the whole of one layer of wire electrode of wire storage cylinder uniform winding from wire electrode
During, wire electrode wire tray damper is all applied with certain damping force to wire tray so that wire electrode wire tray can be in wire storage cylinder
When rotation, wire storage cylinder passes through the wire electrode transmission strong to wire electrode wire tray, so that wire electrode wire tray can overcome
The frictional force that damper produces to wire tray, and simultaneously rotating with wire storage cylinder, and guarantee wire electrode can be of moderate size with one and
It is wrapped in wire storage cylinder last layer constant even tension, be unlikely to appearance because of electrode thread intension power tensioning electrode not and repeatedly
The phenomenon of silk.When the wire electrode on wire storage cylinder is wound into required length, stop operating wire storage cylinder, and wire electrode wire tray is in resistance
Also stop operating rapidly under the frictional force effect of Buddhist nun's device.Then wire electrode is cut off from wire tray, remaining wire electrode in wire tray
Under the pressure of silk pressing spring leaf 16 acts on, loose, sleave, bending, breakage phenomenon would not occur.Finally manually draw
The conductive polar filament place of cutting off one end bypasses whole directive wheels on guide frame, conducting block in order, passes through workpiece, and last wraparound wire storage cylinder is another
The solid silk screw in one end is fixed, and makes wire electrode form closed circulation, and will be fast to support 2 and electric spark by unscrewing bolt C11
Fast wire cutting machine separates.
When the wire electrode in wire electrode wire tray has used, need to take off wire electrode wire tray and changed.First lead to
Overregulate bolt 5 to screw outward, damping fin does along cross bar in the presence of spring 1 and dorsad moves, make between damping fin away from
From the width more than wire electrode wire tray;Then wire tray support bar 8 is separated with wire electrode wire tray and support 2, and by wire electrode silk
Disk takes off, and changes new wire electrode wire tray, is then connected wire tray support bar 8 respectively with wire electrode wire tray and support 2 again.
