Abstract
The invention discloses a single-direction curved corrugated pipe. The single-direction curved corrugated pipe comprises an integrally molded pipe body, wherein one side of the pipe body is provided with a flexible wall part which can be stretched, the other side of the pipe body is provided with a flat wall which can penetrate through the pipe body along the axis direction of the pipe body, and the flexible wall part and the flat wall are smoothly connected to form the pipe body with a hollow cavity. The pipe body is formed by smoothly connecting the flexible wall part which can be stretched and the flat wall. By adopting the structure, when the pipe body is bent, the flexible wall part is stretched, the flat wall only can be bent and play a guide effect, any position on the flat wall is bent along a specific direction, the pipe body can be bent only along one direction, the single-direction oriented bend of the corrugated pipe is realized, and the single-direction curved corrugated pipe can be used as a hollow reinforcing rib to produce an outer corrugated plastic winding structure wall pipe material.
Description
Technical field
The present invention relates to a kind of bellows, particularly relate to a kind of bend in one direction 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.
Summary of the invention
Object of the present invention, is to provide a kind of bend in one direction bellows.
The solution that the present invention solves its technical problem is: bend in one direction bellows, it comprises integrated tube body, the side of described tube body is provided with the flexible wall section that can be stretched, the opposite side of tube body is provided with the straight ancient piece of jade, round, flat and with a hole in its centre that the axial direction along tube body runs through, and between described flexible wall section with a straight ancient piece of jade, round, flat and with a hole in its centre, round and smooth connection forms the tube body that has hollow cavity afterwards.
As the further improvement of technique scheme, described flexible wall section has the ripple of a plurality of indent evaginations, 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 outer wall of a described straight ancient piece of jade, round, flat and with a hole in its centre is provided with the parallel straight groove of multiple tracks, and the angle of the longitudinal center line of described straight groove and tube body is acute angle.
As the further improvement of technique scheme, the outer wall of a described straight ancient piece of jade, round, flat and with a hole in its centre is provided with knurled recesses.
