Description
Technical field
The utility model is to be related to a kind of protective device, especially a kind of filament breakage protection device of numerically controlled wire cutting machine.
Background technology
Wire-cut Electrical Discharge Machining becomes indispensable in machinery manufacturing industry due to its unique process principle and feature
A kind of advanced processing method, using very universal in mechanical industry.In processing, the wire electrode as cutter（It is common
Molybdenum filament）In use, if fracture of wire occurs, the fracture of wire guard block in equipment will make wire transporting motor hard stop.But
Found in real work, the original fracture of wire guard block of equipment is since the element on fracture of wire protection board is often burned and is often lost
Effect, after wire electrode is broken, wire transporting motor is also remaining in operation, and the wire electrode of submitting, which is wrapped on wire storage cylinder, to be difficult to clean up, and is made
Scrapped into wire electrode, also wire transporting motor can be caused to burn out sometimes, greatly affected production.Wire electrode can operationally go out at the same time
Existing " shake " phenomenon.Therefore, wire cutting machine tool fracture of wire protection becomes the problem of equipment one is in urgent need of strengthening.
The content of the invention
The purpose of this utility model be to provide it is a kind of it is structurally simple, economical be applicable in, the numerically controlled wire cutting machine of dependable performance
On filament breakage protection device.
The utility model is solved by following technical proposal：The protective device includes numerically controlled wire cutting machine, fortune
Silk mechanism, wire electrode coil holder mechanism, are made of wherein setting one in wire electrode coil holder mechanism tight silk wheel carrier and limit switch
Filament breakage protection device.
Further, one end of the tight silk wheel carrier is fixed on the sliding block of wire electrode coil holder mechanism, and the other end is freely
End, the end are equipped with a small thread pressing wheel, and thread pressing wheel is pressed on the wire electrode of operation.
Further the limit switch switchs for contact, cooperates with the thread pressing wheel.
The beneficial effects of the utility model be by this set filament breakage protection device, on the one hand can be effectively to wire cutting machine tool
Process and equipment play a protective role in itself.On the other hand wire electrode can be allowed to be in tensioned state all the time, eliminates electricity
" shake " phenomenon that polar filament operationally occurs, stabilizes processing quality.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment wire cutting machine tool.
Fig. 2 is the utility model embodiment wire cutting machine tool wire transporting motor and the side view of wire storage cylinder part.
Fig. 3 the utility model embodiment filament breakage protection device structure diagrams.
Embodiment
With reference to embodiment, the utility model is described in further detail.
As shown in the figure, the protective device includes numerically controlled wire cutting machine 1, steel wire storage mechanism 2, wire electrode coil holder mechanism 3, wherein
One filament breakage protection device being made of tight silk wheel carrier 4 and limit switch 5 is set in wire electrode coil holder mechanism 3.
One end of the tight silk wheel carrier 4 is fixed on the sliding block 11 of wire electrode coil holder mechanism 3, and the other end is free end, if
There is one small thread pressing wheel 6, thread pressing wheel 6 is pressed on the wire electrode 7 of operation.
The limit switch 5 switchs for contact, cooperates with the thread pressing wheel 6.
Steel wire storage mechanism 2 and electrode wires frame mechanism 3 are the components for supporting wire electrode movement to work.In steel wire storage mechanism 2,
Wire storage cylinder 10 is with its positive and negative rotation, so as to drive wire electrode 7 by certain linear velocity by wire transporting motor 8 by shaft coupling 9
Move back and forth, wire electrode 7 is fitly arranged and is wound on wire storage cylinder 10, as shown in Figure 2.Wire electrode 7 is by being separately mounted to upper silk
Arm 12 and four guide wheel assemblies 14 at lower 13 both ends of silk arm support, as shown in Figure 3.
The fixing end of tight silk wheel carrier 4 is fixed on by bolt 15 on the sliding block 11 of wire electrode coil holder mechanism 3, another free end
The small thread pressing wheel 6 being equipped with is pressed on the wire electrode 7 of operation, once in work wire electrode be broken, one end with thread pressing wheel 6 due to
Dead weight free-falling, collides the contact of limit switch 5, and limit switch 5 passes the signal along to wire transporting motor 8, it is stopped automatically
Only.Further, since pressuring action of the tight silk wheel carrier 4 to wire electrode 7, making wire electrode 7, the moment keeps tensioned state in operation, disappears
Except " shake " phenomenon, the machining accuracy of part is improved, improves product quality.
It can be seen from the above that filament breakage protection device of the utility model as wire cutting machine tool, simple in structure, good practical effect,
The deficiency of original equipment fracture of wire protective capability is compensate for, the wire electrode caused by fracture of wire is effectively prevent and winds and scrap, very
To the occurrence of causing motor burning, and by the compression to running wire electrode, " shake " phenomenon is eliminated, is effectively carried
The machining accuracy of high workpiece, meets the needs of production.
