The wire tensioning device comprises a movable guide wheel, a movable guide wheel base and a fixed ring guiding device. The fixed ring is connected with one end of a force executing cable. The wire tensioning device also comprises a reversible motor whose output torque is adjustable and the output shaft sleeve of the reversible motor. The output shaft sleeve is connected with the other end of the force executing cable whose both ends are always in the dynamic balance state. An operator can continuously adjust the tension of the electrode wire in the continuous operation to keep constant tension to workpieces and to improve the surface roughness of the cut workpieces. The utility model has the advantages of simple structure, reasonable design and convenient operation.
Description
The utility model relates to a kind ofly represents cutter with electrode, acts on metal-working plant auxiliary device, the especially improvement of wire cutting machine wire electrode constant tension mechanism on the workpiece with the electric current high concentration.
Chinese patent 92208036 discloses a kind of wire cutting machine wire electrode constant tension mechanism, as Fig. 1: this mechanism comprise line storage tube 1 ', guide wheel 7 ', wire electrode 2 ', wire electrode 2 ' by wire storage tube 1 ' through guide wheel 4 ', 5 ', 7 ' form loop to Metal Cutting processing.In this loop, be provided with the weight 8 that can move both vertically ', wire electrode forms this loop around the guide wheel on the weight 7 ' back, this weight is made up of main part and counterweight 10 ' two parts.Need change the counterweight that adapts with it according to the not coplanar of workpiece and wire electrode specification.Counterweight 10 ' with weight 8 ' bolt for combining 9 ' be connected, in order to prevent the swing of weight, around weight, establish guide rail 11 '.Face is in actual cutting process, because loss, the cross sectional shape of wire electrode reduces continuous the variation.The tension force of constant setting is concerning ever-reduced wire electrode cross section, and the tension that its wire electrode unit cross-sectional area is born but constantly increases, and so continues, and to a certain degree causing fracture of wire, directly influences the service life of wire electrode.In addition, the wire electrode of plurality of specifications also needs the counterweight of multiple weight corresponding with it, and the structure spare and accessory parts are increased, and operating performance is numerous and diverse, and causes the cut workpiece surface roughness to differ easily.
At above-mentioned deficiency, the utility model proposes a kind of improved wire cutting machine wire electrode constant tension mechanism, the mechanism by adjustable tension obtains dynamic balancing, makes the constant tension that acts on the wire electrode unit cross-sectional area, improve functional reliability, improve the cut workpiece surface roughness.
Utility model is achieved in that a kind of wire cutting machine wire electrode constant tension mechanism, form loop by silk tube 1, guide wheel 2, tight silk device 3,4,5,7,8, application of force rope 6, wire electrode 9, it is characterized in that: the guider of being made up of movable guide wheel 3 that can slide up and down along lead 5 and the movable guide wheel pedestal 4 that is connected with it is connected in an end of application of force rope 6, is connected in the other end of application of force rope 6 as the output sleeve 7 of the reversible electric machine 8 in application of force source; The wire electrode 9 that is in the loop is enclosed within on the movable guide wheel 3.
The bottom of the movable guide wheel pedestal 4 porose retainer ring 12 that is connected, an end of application of force rope 6 penetrates in this retainer ring 12.
The other end of application of force rope 6 penetrates in the through hole 13 of reversible electric machine output sleeve 7.
The utlity model has simple in structure, reasonable in design, use, install, debugging characteristics very easily all.The utility model makes the wire electrode of different size can keep constant tension under different processing situations, has prolonged the service life of wire electrode.Simultaneously, also cancelled counterweight, simplified the structure and reduce cost.When the wire electrode of wire cutting machine relaxed in the processing work process, the voltage that the operator only need change on the reversible electric machine both can change the output torque of motor, thereby realized changing the purpose of wire electrode loop tension force.

Now further narrate by reference to the accompanying drawings structure of the present utility model:
Referring to 2-4, by silk tube 1, guide wheel 2, tight silk device 3,4,5,6,7,8 And wire electrode 9 forms the utility model. Tight silk device comprises by reversible electric machine 8, motor Output sleeve 7, the force application mechanism that application of force rope 6 forms and by lead 5, movable guide wheel 3 The movable guide wheel pedestal 4 affixed with movable guide wheel 3, and with movable guide wheel pedestal 4 screw threads Two parts of guiding mechanism that the retainer ring 12 that connects forms. Movable guide wheel pedestal 4 edges Lead 5 and slidably contact, what be threaded from the below of movable guide wheel pedestal 4 consolidates Penetrate application of force rope 6 in the fixed ring, the other end of described application of force rope penetrates reversible electric machine output In the through hole 13 that arranges in the middle of axle sleeve 7 grooves, application of force rope is hidden in described through hole 13 In and twine affixed with axle sleeve 7. Application of force rope 6 is in plumbness all the time, and at another End is in tangential direction with the output sleeve 7 of reversible electric machine. Reversible electric machine output is suitable, Anticlockwise moment drives axle sleeve 7 and rotates, thus tension or loosen application of force rope 6, with this Reach the purpose that changes tension force to the loop of wire electrode.
It is anti-that oil baffle disc 34 is set between the inside of the little shape groove 31 of movable guide wheel and the projecting shaft 33 End that oil stain, dust splash, spacer 36,38 be set between the inner bearing 35,37.
By silk tube 1, guide wheel 2, but the movable guide wheel 3 of vertical up-or-down movement, wire electrode 9 The loop that forms is when wire electrode causes the wire electrode envelope because of continuous cut workpiece 10 When loop circuit tension force reduces, only need to regulate according to actual conditions and be applied to reversible electric machine Voltage on 8, thus the output torque of change reversible electric machine 8 makes to be connected in output shaft Application of force rope 6 on the axle sleeve 7 tightens up, and at this moment application of force rope 6 gives guide wheel by retainer ring 12 4 one pulling force vertically downward of pedestal, drive activity guide wheel 3 are vertically downward mobile, from And make wire electrode 9 tensionings that are wrapped on the little shape groove 31 of movable guide wheel. Otherwise, if When needing lax electrode wire 9, as long as will be wrapped in the application of force of reversible electric machine output sleeve Rope 6 loosens, at this moment, be enclosed within wire electrode 9 on the little shape groove 31 of movable guide wheel can be subjected to The impact of upper pulling force and adjust the tension force of wire electrode 9. Make whole wire electrode loop All the time be in dynamic equilibrium state. 11 is jackscrew.
Embodiment 1: reversible electric machine 8 for ND-77, act on the voltage V angle speed omega on the motor, the diameter D of axle sleeve 7 and output torque, voltage are linear.Application of force rope 6 adopts nylon wire, is positioned at the tangential direction of axle sleeve 7.
