Abstract
The utility model belongs to the technical field of electric discharge machining and particularly relates to a combined electrode for an electric discharge machine tool, which comprises an electrode. An insulating brush is arranged on the electrode; the bottom end of the insulating brush is lower than that of the electrode; the insulating brush is attached onto the periphery of the electrode; or a through groove is arranged on the electrode; the insulating brush is arranged inside the through groove; or the insulating brush is arranged on a rubber ring arranged on the outer circumference of the electrode; and the inner diameter of the rubber ring is smaller than the outer diameter of the electrode. The soft and wear-resistant insulating brush is arranged on the electrode of the electric discharge machine tool and rotates along with the electrode; and the insulating brush damages a carbonized protective layer formed on the surface of a workpiece while a carbonized protective layer on the surface of the electrode is not affected in the process of rotating, thereby the combined electrode achieves the purposes of improving machining efficiency and reducing electrode loss.
Description
Technical field:
The utility model belongs to the spark erosion technique field, is specifically related to a kind of spark-erosion machine tool combination electrode.
Background technology:
The electric spark cooling fluid is generally the hydrocarbon of kerosene and so on, in discharge process thermal decomposition will take place, and produces a large amount of free state carbon particulates, and the easy and metal particle combination of the carbon particulate of this free state forms metal carbides particulate group, is also referred to as micelle.It is electronegative that the positively charged that this micelle has has; under effect of electric field; the micelle of positively charged is shifted to negative pole, and electronegative micelle is shifted to positive pole, and these micelles are adsorbed on the surface of both positive and negative polarity; through accumulation after a while; can form the chemisorbed carbon-coating of certain intensity and thickness at positive and negative polarities, be referred to as the carbon black film usually, this carbon black film not only has protective effect to workpiece and electrode; also be attached with the galvanic corrosion thing easily, this phenomenon is referred to as blanketing effect.This layer carburization zone is undoubtedly a kind of good thing concerning electrode, can play a protective role to electrode, reduce the loss of electrode, but this layer carburization zone then is a unfavorable factor that influences working (machining) efficiency for processing work.How can rationally utilize blanketing effect? optimal way is exactly that carbon black film destroy with surface of the work falls, and don't damages the carbon black film of electrode surface, so not only can improve the working (machining) efficiency of workpiece, has also reduced the loss of electrode material.
The utility model content:
In sum; in order to overcome the deficiency of prior art problem; the utility model provides a kind of spark-erosion machine tool combination electrode; it is that soft and wear-resisting insulated brush are set on the electrode of spark-erosion machine tool; insulated brush rotates with electrode, and in the process of rotation, insulated brush destroys the carbonization protective layer that surface of the work forms; and the carbonization protective layer of electrode surface is unaffected, thereby reaches the purpose that improves working (machining) efficiency and reduce export license.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of spark-erosion machine tool combination electrode, it comprises electrode 1, and wherein: described electrode 1 is provided with insulated brush 3, and the bottom of insulated brush 3 and the distance between workpiece are less than the bottom of electrode 1 and the distance between workpiece.
Further, described insulated brush 3 or be arranged on the excircle of electrode 1; Perhaps electrode 1 is provided with groove 4, and insulated brush 3 is arranged in the groove 4; Perhaps insulated brush 3 is arranged on the rubber ring 2, and rubber ring 2 is arranged on the excircle of electrode 1, and rubber ring 2 internal diameters are less than electrode 1 external diameter.
Further, described insulated brush 3 is the rubber-covered brush; Or be the insulation hairbrush; Or be that the emery wheel bar insulation is brushed.
The beneficial effects of the utility model are:
1, the utility model is that soft and wear-resisting insulated brush are set on the electrode of spark-erosion machine tool, insulated brush rotates with electrode, in the process of rotation, insulated brush destroys the carbonization protective layer that surface of the work forms, and the carbonization protective layer of electrode surface is unaffected, thereby reaches the purpose that improves working (machining) efficiency and reduce export license;
2, the utility model is simple in structure, and is easy to install, and cost is low, and the service efficiency height can reduce the production cost of enterprise greatly, enhances productivity.
Description of drawings:
Fig. 1 is first kind of structural representation of the present utility model;
Fig. 2 is the structural representation of the insulated brush of the utility model Fig. 1;
Fig. 3 is second kind of structural representation of the present utility model;
Fig. 4 is the elevational schematic view of the utility model Fig. 3;
Fig. 5 is the schematic perspective view of second kind of structure of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment one:
As shown in Figure 1 and Figure 2, a kind of spark-erosion machine tool combination electrode, it comprises electrode 1, the excircle of electrode 1 is provided with rubber ring 2, the internal diameter of rubber ring 2 is less than the external diameter of electrode 1, insulated brush 3 is fixed on the rubber ring 2, and insulated brush 3 is the rubber-covered brush, and the bottom of insulated brush 3 and the distance between workpiece are less than the bottom of electrode 1 and the distance between workpiece.
During use; insulated brush 3 is with electrode 1 rotation; the bottom of insulated brush 3 and the distance between workpiece are less than the bottom of electrode 1 and the distance between workpiece; therefore; during rotation; the bottom end face of insulated brush 3 contacts with surface of the work; in rotary course, produce the mill sassafras with surface of the work; the carbonization protective layer that surface of the work is formed destroys; do not destroy and can not produce the carbonization protective layer of electrode surface; thereby play the purpose that improves working (machining) efficiency and reduce export license, the internal diameter of rubber ring 2 like this can be with on rubber brush 3 cylindrical attached to electrode 1 tightly less than the external diameter of electrode 1.
Embodiment two:
As Fig. 3; Fig. 4; shown in Figure 5; repeat embodiment one; following difference is arranged: electrode 1 is provided with groove 4; insulated brush 3 is arranged in the groove 4; insulated brush 3 is emery wheel bar insulation brush; because emery wheel bar insulation brush is harder; and when reality is used, need insulated brush 3 that certain pliability is arranged; therefore spring 5 is set in groove 4; insulated brush 3 is arranged in the groove 4 by spring 5; insulated brush 3 can freely stretch in groove 4; in use, emery wheel bar and surface of the work produce the mill sassafras, and process medium plain emery wheel bar comes the surface of grinding work piece by the spring applied pressure; thereby the carbonization protective layer of surface of the work is destroyed, play the purpose that improves working (machining) efficiency and reduce export license.
Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art, as long as do not exceed the thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
