The functions of the wire wheel and the wire stopper on the wire cutting machine tool in electric discharge are generally two. One is to prevent the wire from swinging significantly during movement, and the other is to use their positioning function to neatly wrap it on the wire cylinder. Of course, the left and right reversing positions of the wire arrangement are also determined by them. The principle for adjusting the wire cutting wire wheel and wire stopper is:
1, Let the distance between the molybdenum wires in the wire cutting machine tool and the wire cylinder in the wire cutting process be about 2mm to prevent wire stacking during the moment of reversing.
2, The medium wire cutting machine tool and the V-shaped groove of the guide wheel jointly limit the wire to a straight line perpendicular to the axis of the guide wheel, to ensure the guiding and positioning effect of the V-shaped groove of the guide wheel on the wire movement.
3, The wire cutting machine's wire wheel and wire stopper should also ensure insulation with the bed, and should not cause short circuits between the wire and the bed due to them.
4, Restrict excessive water from being carried onto the spool. At any time, the wire discharge wheel and stopper of the wire cutting machine should not cause excessive resistance to the operation of the wire, as any impact it has on the working tension of the wire will have a negative effect. It should also be noted that the parts must be cleaned thoroughly before installation, which is crucial for the length of service life!
