Abstract
The utility model discloses a kind of guide wheel device of improvement, comprise and be arranged on the V-type directive wheel in once directive wheel box, impeller and the water injection hole being arranged on lower directive wheel box upper surface, described impeller and V-type directive wheel is isometrical is fixedly arranged on same guide wheel shaft, be placed in the side of V-type directive wheel, described water injection hole is arranged on the top position of impeller, institute's waterflood direction and impeller cylindrical tangent, described water injection hole is connected with high pressure water injection pipeline.The circumferential edge position of described impeller is ratchet structure.Described material used for impeller is plastics.The utility model is simple and practical, with low cost, is the guide wheel device that an efficiency is worn in a kind of raising easy to use, effective.
Description
Technical field
The utility model relates to
electric spark linear cutting machinetechnical field, is specifically related to
a guide wheel device for improvement, is mainly used inin wire cutting machine tool Wire-conveying mechanism of quick walk.
Background technology
Wire cutting machine tool, adopts automatic wire feed or manually wears a technology and all can run into a same difficult problem, and namely wire electrode is through the horizontal direction vertically become from top to bottom after lower wire guiding nipple from front to back, and its corner is difficult to pass through smoothly.Prior art is the directive wheel by being equipped with a band V-type groove, and wire electrode is obedient to V-type groove, expects that wire electrode completes guiding by rotating along directive wheel with V-type groove frictional force.There is following shortcoming in this technical scheme: diameter is that the frictional force of the thin copper wire of 0.2mm and V-type groove is very little, is not enough to promote directive wheel, and namely end user's work is manually worn silk and sent into some resistance is puckery and still can operate, and also sometimes needs repeatedly just can complete unavoidably.When adopting partially hard diameter to be 0.3mm or partially soft diameter to be the cutting wire of 0.15mm string diameter, in 90 ° and turned round more difficult, directive wheel non rotating cannot complete turning function at all.Known in the industry, automatic or semi-automatic failure 60 ~ 70% of wearing silk is just this.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide "
a kind of guide wheel device of improvement".Should
devicesimple and practical, with low cost, be a kind of
easy to use, effectively improvewear thread efficiency
guide wheel device.
To achieve these goals, the utility model is achieved through the following technical solutions:
main technical scheme is, a kind of guide wheel device of improvementcomprise and be arranged on the V-type directive wheel in once directive wheel box, impeller and the water injection hole being arranged on lower directive wheel box upper surface, described impeller and V-type directive wheel is isometrical is fixedly arranged on same guide wheel shaft, be placed in the side of V-type directive wheel, described water injection hole is arranged on the top position of impeller, institute's waterflood direction and impeller cylindrical tangent, described water injection hole is connected with high pressure water injection pipeline.
Further technical scheme is, the circumferential edge position of described impeller is ratchet structure.
Further technical scheme is, described material used for impeller is plastics.
The utility model compared with prior art tool has the following advantages:
1. should
devicesimple and practical, with low cost, be a kind of
easy to use, effectively improvewear thread efficiency
guide wheel device.
2. because of this
devicein impeller and V-type directive wheel is isometrical is fixedly arranged on same guide wheel shaft, water filling
Hole is arranged on the top position of impeller, utilizes high pressure fine current to inject impeller, and by vane rotary, drive directive wheel to rotate, the wire electrode be clipped in directive wheel V groove is turned round smoothly and constantly carries thereupon.Increase substantially and wear an efficiency.
3., because the circumferential edge position of described impeller is ratchet structure, material used is plastics.The light grain husk of impeller easily drives.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional structure schematic diagram.
Fig. 3 is of the present utility model
exploded perspectivestructural representation.
In figure: 1, V-type directive wheel, 2, impeller, 3, lower directive wheel box, 4, water injection hole.
Detailed description of the invention
Below by non-limiting example, set forth the utility model further, understand the utility model.
Embodiment
The utility model as shown in Figure 1, Figure 2, Figure 3 shows,
main technical scheme is, a kind of guide wheel device of improvementcomprise and be arranged on the V-type directive wheel in once directive wheel box, impeller and the water injection hole being arranged on lower directive wheel box upper surface, described impeller and V-type directive wheel is isometrical is fixedly arranged on same guide wheel shaft, be placed in the side of V-type directive wheel, described water injection hole is arranged on the top position of impeller, institute's waterflood direction and impeller cylindrical tangent, described water injection hole is connected with high pressure water injection pipeline.
The circumferential edge position of described impeller is ratchet structure.
Described material used for impeller is plastics.
In sum, the utility model is simple and practical, with low cost, is a kind of
easy to use, effectively improvewear thread efficiency
guide wheel device.
