An upper cross arm and a lower cross arm of the wire frame are provided with a couple of wire electrode revolving guide devices for supporting inclined guide polar filaments. The distance between the support point of the wire electrode and an upper plane and a lower plane of a work piece can be obviously reduced, and the range of cutting taper can be enlarged. The wire frame is provided with a device for stopping working fluid to pass with the wire electrode. The utility model can solve the problem that the working fluid can result in environmental pollution caused by the drip of a belt of the wire electrode. The utility model is suitable for wire frames with stationary height and wire frames with liftable height.

Description

The wire cutting machine coil holder of revolution guiding cutting tapering

The utility model relates to a kind of wire cutting machine coil holder, particularly a kind of wire cutting machine coil holder of wire electrode revolution guiding cutting tapering.

Existing quick wire type upper block is made the wire cutting machine coil holder that two coordinate axially-movables of U, V have the tapering cutting function, because upper block wire electrode strong point plane lower tumbler wire electrode strong point on the workpiece is big apart from the distance of workpiece lower plane, reduced the scope of cutting tapering, the DK7725TC lathe of producing with domestic Chengdu Radio Special Equipments Factory is an example, and maximum cutting tapering is 15 °.And the external molded lines of the wire at a slow speed cutting off machine of producing, plan range is little up and down apart from workpiece owing to the strong point about the wire electrode, so under identical U, V axial stroke situation, the tapering cut coverage can reach 24-30 °, a certain distance is arranged by contrast.

Task of the present utility model provides the wire cutting machine coil holder that a kind of upper block is done U, two coordinate axially-movables of V, turn round guider by dress pair of electrodes silk on transverse arm and the lower cross arm thereon, dwindle the wire electrode strong point and the workpiece distance between two planes up and down with this, reach the purpose that enlarges the tapering cut coverage.

The utility model is to realize like this, on the Top Crossbeam of coil holder, be equipped with two reference axis of upper block U.V to feed system, below the upper block of coil holder Top Crossbeam, a wire electrode that can support is housed makes the revolution guider of gyration, a guide is housed on it, above the lower cross arm lower tumbler, a wire electrode that can make support is housed equally makes the revolution guider of gyration, a guide is housed on it, last turning down guider serves as the revolution axle center with the wire electrode of vertical support between the guide of upper block and the guide lower tumbler below it and its top, guide on the last turning down guider, it is the revolution synchronously of mutual center symmetry by holding position, when carrying out the tapering cutting, this supports the wire electrode of inclination to the revolution guider by the slope of setting, and do gyration, and its angle of revolution is followed the tracks of the round track of walking of upper block all the time, and the motion of revolution guider is by computer control.

Owing to take such scheme, the strong point of cutting wire electrode when harmful at tapering to workpiece up and down the distance between two planes obviously dwindle, can reach under identical U, two reference axis strokes of V situation, can reach the scope that enlarges the cutting tapering, such scheme both had been applicable to highly fixing coil holder, was applicable to the coil holder of height lifting again.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 7. stop working solution to pass through schematic diagram of device.

In Fig. 1, coil holder 1 is equipped with Top Crossbeam 2 lower cross arms 3, and the device 4 and the upper block 5 that stop working solution to pass through are housed on Top Crossbeam 2, and wire electrode revolution guider 6 is housed below upper block 5, does gyration by stepper motor 7 transmissions; Lower tumbler 8 is housed on lower cross arm 3, and wire electrode revolution guider 9 is equipped with in the top of lower tumbler 8, does gyration by stepper motor 10 transmissions.Know from Fig. 1, inclined electrode silk 11 by 6,9 supports of revolution guider, its strong point is to the distance on workpiece two planes about in the of 12, and existing all kinds of tapering wire cutting machine tool of domestic quick wire type prior art is obviously dwindled, and this new structure can reach and enlarge the tapering cut coverage.

Consult Fig. 1,2, U axis rail 13V axis rail 14 is housed on Top Crossbeam 2, U axis rail 13 is to be connected with stepper motor feed system 16 by stationary links 15 to do the U axially-movable, and V axis rail 14 is done the V axially-movable by 17 transmissions of stepper motor feed system; Revolution guider 6 is housed below the front end upper block 5 of U axis rail 13, on the revolution guider 6 guide 18 is housed; Revolution guider 9 is housed above the front end lower tumbler 8 of lower cross arm, on the revolution guider 9 guide 19 is housed; Upper block 5 and guide 18 lower tumblers 8 are in vertical position with wire electrode 11 between the guide 19, and

revolution guider

6,9 is as the revolution axle center; Mutual center,

guide

18,19 its positions symmetry, revolution synchronously; When the cutting tapering, this supports the wire electrode that tilts and does gyration by the slope of setting the revolution guider, and its angle of revolution is to follow the tracks of the round track of walking of upper block all the time, and wire electrode revolution guider is by computer control.

Guide on the

revolution guider

6,9 is implemented structure two, and Guiding wheel structure and guide member arrangement now are described below:

Embodiment one, consults Fig. 3,4, is illustrated as guide and adopts the Guiding wheel structure principle, and revolution guider 9 is housed above lower cross arm 3 lower tumblers 8, turns round unit's dish 20 bearings at it and sits on 21, and guide wheel 22 is housed, and wire electrode is rolled by guide wheel 22 and leads.

Embodiment two, consult Fig. 5,6, be illustrated as guide and adopt the guide block structure principle, revolution guider 9 is equipped with in the top that is contained in lower cross arm 3 lower tumblers 8, on its revolution unit dish 20, guide pad 23 is housed, guide pad 23 is that fan-shaped first arc 24 of R is formed by radius, fan-shaped first arc position has V-shaped groove 25, and wire electrode 11 is by V-shaped groove 25 slide-and-guides on fan-shaped first arc.

Be contained in the Guiding wheel structure principle on the Top Crossbeam revolution guider and the guide of guide block structure principle, identical on its structure and the lower cross arm, direction is opposite by adorning.

During online cutting processing, the wire electrode of high-speed motion can adsorb to pass is with working solution, the approach part causes a bespatter to dye, for overcoming above-mentioned shortcoming, designed a kind of device that can stop working solution to pass through, its structural principle as shown in Figure 7, stop working solution by device by several godet roller cross arrangements, when the wire electrode 11 that is adsorbed with working solution is guided at a high speed left when godet roller 26 is folded to godet roller 27 by upper block 5, the working solution that be adsorbed on wire electrode 11 this moment then continues inertia forward, working solution is separated for the first time with wire electrode, when godet roller 27 was folded to godet roller 28 motions, the remaining working solution that is adsorbed on the wire electrode separated wire electrode once more, after repeatedly bending the break-in campaign again, the working solution that is adsorbed in wire electrode is hindered can not can be solved because of wire electrode passes and be with working solution to influence the working environment problem with wire electrode forward.
