The present invention solves the problems of the technologies described above the technical scheme that is adopted:
By to the discovering of aforesaid bitubular electric spark linear cutting machine, when the constant tension on the wire electrode of electric spark linear cutting machine, its duty is best.
For this reason, the present invention has obtained: a kind of permanent tension force fortune silk method of electric spark linear cutting machine, comprise that wire electrode carries out two-way reciprocal transfer movement between two tubes, and wire electrode is back and forth being transported in the process constant tension on it.
For realizing the constant tension on the wire electrode, in fortune silk process, back and forth the wire electrode of transfer movement be subjected to another tube damping force in the other direction again, and the difference of driving force and damping force is constant when being subjected to a driving force that tube provided.Wire electrode can keep constant tension in entire work process like this.
The driving force that above-mentioned silk tube is subjected to is supplied with by clutch, transmission device by motor, by clutch from close, do not make silk tube not or be subjected to the driving force of motor, correspondingly the damping force that is subjected to of another tube is produced by damper, transmission device, and, do not make the silk tube not or be subjected to the damping force of damper by controller control.
Above-mentioned controller also can be controlled the size of the damping force of damper, puts on the easier control of damping force, adjustment and quantification on the silk tube like this, also with regard to the constant tension on the easier realization wire electrode.
For realizing above-mentioned fortune silk method, develop the electrode wire constant-tension wire-conveying device of electric spark linear cutting machine accordingly, it comprises wire electrode, support, main motor, on, following silk tube, with two clutch and dampers that tube is corresponding, be used to connect main motor and clutch, main motor and damper, damper is with some transmission devices of tube and be used for solenoidoperated cluthes and the control device of damper, described main motor, the silk tube, damper, clutch components is rack-mount, wire electrode branch is around last, on the following silk tube, control device is controlled main motor, and alternately one of them is in the state of closing with two clutches, and correspondingly by corresponding transmission device control damper alternating action.
Said apparatus realizes that by the control of control device to clutch and damper two tubes alternately are activated the effect of power or damping force.Two tubes obtain driving force (square) by connected clutch from main motor, simultaneously can obtain damping force (square) from the damper of correspondence by transmission device again, what even tube was subjected to is driving force (square), what then another tube was subjected to is opposite direction damping force (square), and vice versa.
During wire electrode work, control by control device, be connected, wire electrode one end organizine tube between following silk tube is connected with main motor and obtains required driving force through clutch by corresponding transmission device, the other end obtains required damping force by corresponding transmission device from the damper of correspondence through another tube again, because driving force and damping force all are the power that this device initiatively produces, especially to damping force, also can set and adjust according to the processing needs by control device, therefore this device is when solving elongation wire electrode problem, can guarantee that again wire electrode is in the duty of constant tension all the time, and this constant tension force can be set and adjust.
The above-mentioned damper that is connected on the transmission device comprises stator and mover two parts, the stator terminal of damper and mover end respectively obtain a rotating speed respectively from the silk tube of drive motors and correspondence, one slow-speed of revolution poor (being differential method) is arranged between two rotating speeds, prolonged the service life of damper.The mover end of damper and stator terminal are by differential, export a damping force (square) and corresponding with it reaction force (square) respectively, damping force (square) affacts on the corresponding silk tube by corresponding transmission device, two reaction forces (square) alternately affact on the main motor of this device, and all the time all with the power output (square) of main motor in the same way.
Compared with prior art, the invention has the advantages that: the wire electrode of electric spark linear cutting machine is when reciprocal transfer movement, it is in the active force that a silk direction of feed that is provided is provided, be subjected to the reciprocal damping force of another tube again, and the constant tension that is subjected on the wire electrode, therefore can guarantee that wire electrode is in suitable duty always, thereby improve the quality of products in time with the electrode thread intension of elongation.
