Description

Bellows and forming module thereof
Technical field
The utility model relates to a kind of bellows and forming module thereof.
Background technique
The advantages such as bellows is lightweight, high pressure resistant with it, good toughness, construction is fast, the life-span is long are widely used, and at present, the flared section of bellows generally adopts two kinds of modes of production: a kind of is online production; Another kind is to adopt special-purpose flaring machine to produce.Adopt the effect of flaring machine production owing to there is no vacuum pumping device, circumferential fin is also set, during production, often depend on the characteristic of bellows raw material, some material can limit the performance after enlarging, the defects such as serious meeting causes leaking, leaking gas, and the life-span is short, and production bellows efficiency is low.
Model utility content
For the technical deficiency of above-mentioned existence, the purpose of this utility model is to provide a kind of bellows and forming module thereof, and it arranges circumferential fin in flared section, for strengthening the intensity of the rear flared section of cutting, guarantees intact, stably connection.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of bellows, comprise bellows main paragraph and be attached thereto the flared section connecing, described flared section comprises interior block and overcoat section, described interior block is the bellows that external diameter is less than the external diameter of described bellows main paragraph, described overcoat section is the external diameter of the interior block described in internal diameter is greater than and the straight tube that is less than the external diameter of described bellows main paragraph, in described overcoat section, be connected with the alice with horn-like enlarging, on described alice, be provided with the circumferential fin that strengthens its intensity.
Preferably, between described interior block and described alice, be connected with excision section, described excision section comprises the interior changeover portion that is connected with described interior block, the outer changeover portion being connected with described overcoat section, the middle transition section between the interior changeover portion described in being connected to and described outer changeover portion.
A kind of forming module of bellows described above, comprise the first module for described bellows main paragraph moulding, for the second module of described flared section moulding, the second described module comprises for the first submodule of described interior block moulding, for the second submodule of described overcoat section moulding, for the 3rd submodule of described alice moulding, and the inwall of the 3rd described submodule has the groove that the shape with described fin matches.
Preferably, the first described module comprises a plurality of main body submodules.
Preferably, the second described module comprises the 3rd submodule described in the second submodule described in the first submodule described in two, one and.
The beneficial effects of the utility model are: the close cutting position in the flared section of bellows arranges circumferential fin, the cutting intensity of enlarging when it can either guarantee to cut, intensity in the time of can guaranteeing flared section connection again, avoid the phenomenons such as cracking, flanging, and then avoid leaking, the phenomenon such as gas leakage, effectively extended working life.
Accompanying drawing explanation
The structural representation that accompanying drawing 1 is bellows of the present utility model (on whole pipe one section);
Accompanying drawing 2 is to being applied to the forming module of the corrugated pipe forming in accompanying drawing 1.
In accompanying drawing: 1, fin; 2, the first submodule; 3, the second submodule; 4, the 3rd submodule; 5, main body submodule.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is described in detail below:
In accompanying drawing 1: what a marked is flared section, what b marked is bellows main paragraph, and what c marked is excision section, and what d marked is overcoat section, and what e marked is interior block, and what f marked is alice.
As shown in Figure 1, a kind of bellows, comprise bellows main paragraph b and be attached thereto the flared section a connecing, flared section a comprises interior block e and overcoat section d, interior block e is the bellows that external diameter is less than the external diameter of bellows main paragraph b, overcoat section d is that internal diameter is greater than the external diameter of interior block e and is less than the straight tube of the external diameter of bellows main paragraph b, on overcoat section d, be connected with the alice f with horn-like enlarging, on alice f, be provided with the circumferential fin 1 that strengthens its intensity, the structure of alice f forms a circumferential guide surface, be convenient to overcoat section d to be placed on the outside of interior block e, in addition, between interior block e and alice f, be connected with excision section c, excision section c comprises the interior changeover portion being connected with interior block e, the outer changeover portion being connected with overcoat section d, be connected to the middle transition section between interior changeover portion and outer changeover portion, when carrying out connection in advance, first in the both sides of excision section c, cut respectively, remove excision section c, on interior block e, install seal ring again, then interior block e is inserted to overcoat section d, on the bellows of just making shown in accompanying drawing 1 one section, it extends and is bellows main body to two ends.
As shown in Figure 2, a kind of forming module for the production of above-mentioned bellows, comprise the first module for bellows main paragraph b moulding, the second module for flared section a moulding, the second module comprises the first submodule 2 for interior block e moulding, the second submodule 3 for overcoat section d moulding, the 3rd submodule 4 for alice f moulding, the inwall of the 3rd submodule 4 has the groove that the shape with fin 1 matches, the first module comprises a plurality of main body submodules 5, according to tubulation specification, need to select the quantity of main body submodule 5, the second module comprises two the first submodules 2, second submodule 3 and the 3rd submodule 4, i.e. two the first submodules 2, second submodule 3 and the common moulding of the 3rd submodule 4 obtain above-mentioned flared section a, the working principle of this forming module and process, also can adopt the form in conventional art, for example by driving mechanism, drive each submodule to circulate successively along the tapping channel of materials in the tube, complete the moulding process of bellows.
