Abstract

The utility model relates to a thimble structure having a base rod, one end of which has a head part; the improvement of the utility model consists in that the other end of the base rod relative to the head uses the special materials combining a second rod with the high-temperature resistance and the wear resistance. Wherein the combined mode between the base rod and the second rod is to combine the base rod with the end of the second rod through the high temperature produced by the current, using the high-frequency hot melt and imposing the reverse high pressure rotation on the base rod and the second rod. Wherein the base rod is the general steel material, while the second rod is the tungsten carbide material, and the special material is the brass or other metal materials. Therefore, the utility model can make the whole have the better strength, improve the service life, and reduce the manufacturing costs.

Description

Thimble structure

(1) technical field:

The utility model system is about a kind of thimble structure, refers to especially a kind of two kinds of unlike materials are combined as a whole, and makes thimble have high strength, belongs to the thimble technology.

(2) background technology:

At present, please cooperate and consult Fig. 7 and shown in Figure 8, it is a kind of known thimble structure, and this thimble has a basic bar 50, and an end of this base bar 50 has a head 51 (as shown in Figure 8);

Wherein, known thimble is all general steel, though the drift 61 that also can be used as general mould 60 usefulness uses (as shown in Figure 8), and, its abrasion resistance extreme difference, intensity are also poor, cause these known thimble life-spans to be reduced;

In addition, the dealer is arranged for reaching preferable abrasion resistance, intensity, and then the whole tungsten carbide that changes over of thimble material that these are known, though have splendid abrasion resistance and intensity, but not only cost improves, and only is the preceding segment portion of thimble because of the section of general thimble use, so wasted material virtually, very unfortunate; Therefore, all disappearances of commonly using thimble as described above have improved necessity in fact.

(3) novel content:

A kind of thimble structure of the utility model, its purpose tie up in providing a kind of and improve service life, and the thimble structure of tool abrasion performance, high-strength characteristic; Provide a kind of produce splendid in conjunction with effect, the not effect of reason external force and produce the thimble structure of fracture.

In order to achieve the above object, the utility model provides a kind of thimble structure, and it has a basic bar, and an end of this base bar has a head; Its improvement is that this base bar is to utilize special substance to have second bar high temperature resistant, the abrasion performance characteristic in conjunction with one with respect to the other end of this head.

Wherein, the combination of this base bar and this second bar system passes to electric current respectively and produces high temperature, and utilizes the high frequency hot melt, again should the base bar and this second bar impose the high back voltage rotation, this base bar is combined with the end of this second bar.

Wherein, this base bar is general steel.

Wherein, this second bar is a tungsten carbide material.

Wherein, this special substance is brass or other metal material.

A kind of thimble structure of the utility model, its advantage is: simple in structure, long service life has the characteristic wear-resistant, that intensity is high, thimble in conjunction with effective, can be, and reduce cost because of external force does not produce fracture.

50 basic bar 51 heads 60 moulds 61 drifts

(5) specific embodiment:

At first, please cooperate and consult Fig. 1 to shown in Figure 6, a kind of thimble structure of the utility model, it has a basic bar 10, and an end of this base bar 10 has a head 11; Its improvement is that this base bar 10 is to utilize the special substance (not shown) to have second bar 20 (as shown in Figures 2 and 3) high temperature resistant, the abrasion performance characteristic in conjunction with one with respect to the other end of this head.

Wherein, this base bar 10 is general steel.

Wherein, this second bar 20 is tungsten carbide materials.

Wherein, this special substance is brass or other metal material.

Wherein, the combination of this base bar 10 and this second bar 20 passes to electric current respectively and produces high temperature, and utilizes the high frequency hot melt, again should base bar 10 and second bar 20 impose the high back voltage rotation, make this base bar 10 combine (as shown in Figure 4) with the end of second bar 20.

By above constituting, please continue to cooperate and consult Fig. 1 to shown in Figure 6, the assembler can apply to the utility model on the drift 31 of general mould 30 usefulness (shown in Fig. 5 and the 6th figure);

And the basic bar 10 of the utility model mainly is general steel, and second bar 20 is tungsten carbide materials, makes thimble major part of the present utility model be still general steel, only few tungsten carbide material that partly utilizes, so, can suitably reduce cost having under the preceding topic of preferable use hardness;

In addition, because the basic bar 10 of the utility model and the combination of second bar 20, be to impose special material in conjunction with the end respectively at both, and pass to electric current respectively and produce high temperature, utilize the high frequency hot melt, again the basic bar 10 and second bar 20 are imposed the high back voltage rotation, make basic bar 10 combine (as shown in Figure 4) with the end of second bar 20, rapidly after the cooling, impose temper again,, make it to be combined as a whole to eliminate the internal stress part, thus, can produce the splendid effect that combines between the basic bar 10 of the utility model thimble and second bar 20, the not effect of reason external force and rupturing is so the utility model utilizes the combination of tungsten carbide to make improve greatly the service life of whole thimble, and has a preferable abrasion performance, high-strength characteristic, dark tool practicality.

Certainly, the thimble structure of the utility model not only can apply to the drift that general mould is used, and in addition, also can make the plastics jigger pin in the plastic molding press, perhaps is the bearing of conveyer belt, has aforesaid use effect equally, and whole applicability is very extensive.

Claims

1, a kind of thimble structure, it has a basic bar, and one of this base bar end has a head; It is characterized in that: this base bar is to utilize that special substance is high temperature resistant in conjunction with a tool, second bar of abrasion performance characteristic with respect to the other end of this head.
