Description
The present invention relates to a kind of bi-motor double wire storage tube multilayer lap wound wire feeder, this mechanism is applicable to the fast wire NC wirecut EDM machine of China.
The operation principle of NC wirecut EDM machine is, high frequency pulse power supply is added between the wire electrode and workpiece that respectively becomes one electrode, wherein wire electrode utilizes high frequency pulse power supply that workpiece is processed with motion state, this moment is by digital control system and coordinate motor servo system control X, the moving handle workpiece of Y coordinate (four add also have U man-hour, the V coordinate) is processed into needed shape.
In the evolution of NC wirecut EDM machine, aspect the wire electrode of cutting tool, forming two absolutely different directions from the beginning, for example: adopt copper wire abroad, wire travelling speed is slow, and its value is 1～10 meter/minute, and is disposable use, China then adopts molybdenum filament, wire travelling speed is fast, and its value is 3～10 meter per seconds, and is reciprocal use.
In sum as can be known, in NC wirecut EDM machine, the wire feeder that the supporting wire electrode is made high-speed motion is an important component part that is closely related with its performance.
Wire feeder on the existing fast wire electrical discharge machine tool all adopts single motor single wire storage cylinder structure, its operation principle will be illustrated in the back in conjunction with the accompanying drawings, the characteristics of this structure are with the receipts of wire electrode and put by a wire storage cylinder and finish, this moment, its row's silk mechanism was subjected to structural limitations to store up silk with multilayer lap wound mode, winding of single layer makes the volume of wire storage cylinder bigger, and Chu Siliang generally has only 150～400 meters, in process, the effect that wire electrode is subjected to high frequency pulse power supply has loss to a certain degree, like this, the life cycle of wire electrode is also just shorter.In addition, when wire electrode extends and is tired, tension force decreases, not only influence machining accuracy when serious, can Yin Songsi that processing is become is impossible, existing single motor single wire storage cylinder structure does not also have infallible measure to control for the tension variation of above-mentioned wire electrode, and all these directly has influence on the machining accuracy and the processing stability of lathe.
Task of the present invention is, a kind of bi-motor double wire storage tube multilayer lap wound wire feeder is provided, the Chu Siliang of wire storage cylinder can be multiplied, also make the tension force of wire electrode can be controlled effectively, thereby make the machining accuracy of lathe and processing stability that great raising be arranged, produce qualitative leap.
The concrete technical measures that solve task of the present invention are, make wire electrode adopt two wire storage cylinder storage silks, wherein each wire storage cylinder respectively is provided with independent drive motors, when a wire storage cylinder provides power to receive silk by its motor, another wire storage cylinder is just provided the tension force of wire electrode and is put silk by its motor, and two states back and forth hockets and finishes the motion of wire electrode; Above-mentioned each wire storage cylinder also respectively is provided with independent row's silk mechanism that can make the multilayer lap wound the wire electrode marshalling, and Chu Siliang is multiplication thereupon also.
In conjunction with the accompanying drawings the embodiment of bi-motor double wire storage tube multilayer lap wound wire feeder of the present invention is described further now.
At first be that the operation principle that has single motor single wire storage cylinder winding of single layer wire feeder now is illustrated, be beneficial to deep understanding invention of the present invention.
In the accompanying drawings
Fig. 1 represents the schematic top plan view of existing single motor single wire storage cylinder winding of single layer wire feeder,
The schematic side view of Fig. 2 presentation graphs 1 wire feeder,
Fig. 3 represents the schematic top plan view of bi-motor double wire storage tube multilayer lap wound wire feeder of the present invention,
The schematic side view of Fig. 4 presentation graphs 3 wire feeders.
By Fig. 1 and 2 as can be known, wire electrode 3 with the winding of single layer mode evenly and marshalling ground on wire storage cylinder 2, the income of wire electrode 3 and emitting all back and forth hockets on a wire storage cylinder 2 by guide wheel 4, this moment, the axle of power motor 1 directly was connected with wire storage cylinder 2, when motor 1 rotation, wire storage cylinder 2 just is driven to rotate, and wire storage cylinder 2 and motor 1 move laterally it by row's silk mechanism 5 simultaneously, are beneficial to the proper alignment of wire electrode 3.When wire electrode 3 moves to one when extreme, make motor 1 reverse rotation by control system, wire electrode 3 is just done counter motion.When wire electrode 3 moves to the other end when extreme, motor 1 i.e. laterally rotation, so hockets to form to move back and forth.
Obviously, it is little measuring by the wire storage cylinder 2 storage silks of said structure pattern, and the life cycle of wire electrode 3 is also just shorter, but also can not make the tension force of wire electrode 3 keep constant, and these are for guaranteeing that machine tool capability is totally unfavorable.
By Fig. 3 and 4 as can be known, wire storage cylinder 2 ' a be rotated counterclockwise wire electrode 3 incomes, this moment by motor 1 ' power is provided and determine wire storage cylinder 2 ' rotating speed, also i.e. silk speed.Motor 1 ' and wire storage cylinder 2 ' between be provided with row's silk mechanism 5 ', this row silk mechanism 5 ' by leading screw, nut sleeve, reduction gearing is to forming with cam control piece etc., its structural shape is similar to row's silk mechanism of single motor single wire storage cylinder, promptly this row silk mechanism 5 ' with wire storage cylinder 2 ' to be connected be the continuous action relation structure of being arranged to have the constant speed ratio, whereby with wire electrode 3 with multilayer lap wound mode evenly and marshalling ground around wire storage cylinder 2 ' on.Simultaneously, wire storage cylinder 2 " wire electrode 3 is emitted, through guide wheel 4 deliver to wire storage cylinder 2 ' on, " provide the tension force of wire electrode 3 by motor 1 this moment.
When wire storage cylinder 2 " on wire electrode 3 will drain the time, the integrality counter-rotating " provides power to make wire storage cylinder 2 " by motor 1 and turns clockwise, wire electrode 3 is by wire storage cylinder 2 " to be taken in.Between motor 1 " with wire storage cylinder 2 ", also be provided with its structural shape and wire storage cylinder 2 ' used identical row's silk mechanism 5 on ", whereby with wire electrode 3 in multilayer lap wound mode evenly and fitly around wire storage cylinder 2 ".Wire storage cylinder 2 ' wire electrode 3 is emitted meanwhile, through guide wheel 4 deliver to wire storage cylinder 2 ' on, this moment is by motor 1 ' the provide tension force of wire electrode 3.
When wire storage cylinder 2 ' on wire electrode 3 will drain the time, state is counter-rotating once more just.Wire electrode 3 comes to this in process and alternately back and forth moves.
Practice shows, because wire electrode can the multilayer lap wound, it is above that the Chu Siliang of wire storage cylinder is twice than prior art, and for example: the embodiment of the invention is 1200 meters, and prior art is generally 300 meters, is no more than 500 meters at most.Therefore, the loss of wire electrode will reduce half at least in process, helps improving the machining accuracy of lathe.Also because wire electrode provides tension force by another motor in motion process, thereby it is constant to control the tension force maintenance, especially in process, can avoid prior art to extend because of wire electrode and the tired phenomenon that makes tension change fully, thereby greatly improve the processing stability of lathe.
