Description
Technical field
The utility model relates to a kind of bellows, particularly relates to a kind of special shaped sylphon bellows.
Background technique
Bellows, has the housing of the cylinder-shaped thin wall wrinkle of multiple transverse wave.Bellows is generally made up of PP, PA or PE material, and it has elasticity, can produce displacement or bend under pressure, axial force, transverse force or Moment.In BENDING PROCESS, because bellows is the housing of the cylinder-shaped thin wall wrinkle with multiple transverse wave, it can bend to any direction.Due to the non-directional flexural property of bellows, it is made to be widely used in the line of Building wood and machinery.In addition, in the production of outer ripple plastic winding structure wall pipe with hollow reinforced rib, also adopt bellows to be hollow reinforced rib, its main cause is utilize bellows energy arbitrarily to bending characteristic.The concrete production method of this structure-wall pipe material is, after the outer surface parcel melten gel of bellows, with spiral winding mode cross-pressure on uncooled winding tube wall, again after the rolling of pinch roller, bellows and melten gel and tube wall fuse together, and form the outer ripple plastic winding structure wall pipe with hollow reinforced rib.But, there is following shortcoming in this technique: 1) because bellows is softer, at the parcel melten gel after being rolled by pinch roller that is heated, the cross section of bellows becomes oval, the ratio between the width of hollow reinforced rib and height is caused to be greater than 1, reduce the ring stiffness of outer ripple plastic winding structure wall pipe, reduce the integral bending of wall pipe; 2) being heated and rolling rear distortion due to bellows, the height of the hollow reinforced rib of this wall pipe can only reach 6 ~ 8% of wall pipe diameter; 3) cross section is that the area of contact of the bellows of ring and tube wall is few, causes both connections weak, reduces the integral bending of wall pipe.
Therefore, be necessary to provide a kind of novel bellows, to overcome above-mentioned technique and structural various shortcoming.
Model utility content
The purpose of this utility model, is to provide a kind of special shaped sylphon bellows.
The solution that the utility model solves its technical problem is: special shaped sylphon bellows, it comprises integrated tube body, described tube body has the ripple of a plurality of indent evaginations, the cross section of tube body is the polygonal with at least one straight line or the closed figure formed for straight line and one section of camber line.
As the further improvement of technique scheme, described polygonal is rectangle or trapezoidal.
As the further improvement of technique scheme, described closed figure comprises straight line and one section of circular arc line or straight line and one section of oval camber line.
As the further improvement of technique scheme, the cross section of described ripple is the one in sharp triangle, obtuse triangle shape, trapezoid shaped, rectangle, toroidal or elliptical shape.
As the further improvement of technique scheme, the material of described tube body is PE, PP, EVA, PVC or ABS material.
The beneficial effects of the utility model are: in the utility model, the cross section of tube body is the polygonal with at least one straight line or the closed figure formed for straight line and one section of camber line, based on said structure, special shaped sylphon bellows can not bend to any direction, can only bend along specific direction, can as hollow reinforced rib for the production of outer ripple plastic winding structure wall pipe.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is further described.
Fig. 1 is side view of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is the cross sectional representation of first embodiment in the utility model;
Fig. 4 is the cross sectional representation of second embodiment in the utility model;

Embodiment
Below in conjunction with accompanying drawing, describe application of the present utility model in detail.
With reference to Fig. 1 ~ Fig. 2, special shaped sylphon bellows, it comprises integrated tube body 1, described tube body 1 has the ripple 10 of a plurality of indent evaginations, and the cross section of tube body 1 is the polygonal with at least one straight line or the closed figure formed for straight line and one section of camber line.
The cross section of tube body 1 is the polygonal with at least one straight line or the closed figure formed for straight line and one section of camber line, based on said structure, special shaped sylphon bellows can not bend to any direction, can only bend along specific direction, can as hollow reinforced rib for the production of outer ripple plastic winding structure wall pipe.
Be further used as preferred embodiment, as shown in Fig. 3 ~ Fig. 4, described polygonal is rectangle or trapezoidal.
Be further used as preferred embodiment, as shown in Fig. 5 ~ Fig. 6, described closed figure comprises straight line and one section of circular arc line or straight line and one section of oval camber line.
Be further used as preferred embodiment, the interval between adjacent ripple 10 is the same, and when tube body bends, ripple is stretched, and the cross section of ripple 10 is the one in sharp triangle, obtuse triangle shape, trapezoid shaped, rectangle, toroidal or elliptical shape.Certainly, the sectional shape of ripple 10 is not limited only to the above-mentioned shape exemplified, and according to the actual needs, can make the ripple that different cross section shape produced by different shaping dies.
As the further improvement of technique scheme, the material of described tube body 1 is PE, PP, EVA, PVC or ABS material.
More than that better embodiment of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
