Abstract
A novel graphite electrode comprises a metal inner rod and an electrical discharge machining (EDM) graphite outer sleeve. Tops of the metal inner rod and the EDM graphite outer sleeve are respectively provided with a hole structure. At the same time, the hole structure of the metal inner rod is provided with inner threads, while a hole in the top of the EDM graphite outer sleeve is a through hole, and a connecting bolt is arranged in the through hole in a bonding mode. The connecting bolt can be used for connecting the metal inner rod and the EDM graphite outer sleeve. The novel graphite electrode is simple in process, convenient to machine, and easy to assemble.
Description
Technical field
The utility model relates to a kind of novel electrode, is specially the novel graphite resistor rod that the spark machined in a kind of die industry is used.
Background technology
Along with the development of science and technology, spark machined is applied in the current die industry more and more, and this processing mode has not only been simplified the traditional handicraft means, and can make the manufacturing of making special-shaped mould become more simple.In the prior art, the spark discharge material mainly uses copper, still, use copper relatively high as the discharge material cost, simultaneously, because the resistance to elevated temperatures of copper itself is general, and weakened at high temperature, thereby more and more be not suitable for present batch production demand.
And isostatic pressing formed graphite has the advantages such as isotropism, high temperature resistant, high strength, and product quality constantly improves always and improve, and replaces gradually copper, becomes the optimal material of making the electric discharge machining utmost point.Abroad current, the usage ratio of graphite and copper is 7:3; And at home, the usage ratio of graphite and copper only is 1:9, thereby graphite material is huge at electrode field application potential.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of novel graphite resistor rod, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of novel graphite resistor rod, comprise inner metal rod and EDM graphite overcoat, wherein, inner metal rod and EDM graphite overcoat top all have pore structure, simultaneously, in the pore structure of described inner metal rod, attack internal thread, and the hole at described EDM graphite overcoat top is through hole, and is bonded with a connecting bolt in through hole, and connecting bolt can be used for bar and EDM graphite overcoat in the connection metal, when guaranteeing conducting function, can prevent effectively that EDM graphite overcoat from coming off from inner metal rod.
In the utility model, described inner metal rod preferably adopts copper bar.
In the utility model, described EDM graphite puts outward and is coated with layer of metal film, so that the electrode that graphite overcoat and inner metal rod form can use by the alternative metals electrode.
Beneficial effect: the utility model is compared with traditional fine copper electrode and is had following advantage:
1, lower material cost: the graphite price with volume only is 50% of copper electrode;
2, process velocity faster: machined speed is 2 ~ 3 times of copper electrode, and does not have burr after the processing; The discharge process velocity is than copper electrode fast 34%～200%;
3, less loss: the coating of spark oil decomposition carbide, compensating electrode loss;
4, lighter weight: the density of graphite only is 1/5 of copper, therefore is more suitable for the discharge in large-scale electrode;
5, material is not yielding: compare with copper electrode, the fusing point of graphite can not be out of shape under the condition of high temperature up to 3650 degrees centigrade, is more suitable in the processing rib electrode.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of novel graphite resistor rod of Fig. 1, in the present embodiment, inner metal rod 1 directly is placed in the groove of EDM graphite overcoat 2, be bonded with a hex bolts 3 in the shrinkage pool 4 that EDM graphite overcoat 2 ends have simultaneously, and can be fixing by hex bolts 3 end thread and inner metal rod 1, when guaranteeing conducting function, can prevent effectively that EDM graphite overcoat 2 from coming off from inner metal rod 1.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
