Abstract
The utility model discloses a corrugated pipe which comprises a pipe body, wherein the pipe body is divided into a thickened straight pipe, an ordinary straight pipe and a flaring, one end of the ordinary straight pipe is connected with the thickened straight pipe, the other end of the ordinary straight pipe is connected with the flaring, the thickening coefficient of the pipe wall of the ordinary straight pipe is 1, the thickening coefficient of the pipe wall of the thickened straight pipe is 1.25, the thickening coefficient of the pipe wall of the flaring is 1.5, and the length of the thickened straight pipe is larger than the length of the flaring. The thickened straight pipe is arranged at the rear end of the flaring of an integral pipe, the thickened straight pipe with the smaller pipe wall thickness is machined after the flaring with the largest pipe wall thickness is machined when the integral pipe is formed, finally, the ordinary straight pipe with the smallest pipe wall thickness is machined, the pipe wall thickness changes smoothly, the pipe wall does not deform easily when the corrugated pipe is formed, and the reject ratio of corrugated pipes is reduced. When the corrugated pipe is used, the thickened straight pipe is connected in the flaring, and the connecting position cannot be damaged easily.
Description
Technical field
The utility model relates to a kind of pipeline, particularly a kind of bellows.
Background technique
Bellows is a kind of common pipeline, is plastic raw material to be melted the back extruded by extruder, is obtained by tractor traction and cooling and shaping again.For making things convenient for it to use and transporting, bellows is when moulding, except straight tube structure, also be everlasting and by joint enlarging be set on the homogeneous tube, and be that node is cut into pieces homogeneous tube with the enlarging, transporting it into only needs it to be accepted from beginning to end (the straight tube afterbody of one section bellows is inserted in the enlarging of another section bellows) behind the place to use and the sealing of fitted seal circle gets final product.
Because the bore of bellow flare is greater than the straight tube bore, when tiling bellows on the ground, enlarging and straight tube accept the pressure maximum of bearing in the place, occur damaged easily, the disclosed bellows of prior art has carried out the tube wall thickening to enlarging to be handled, and the coefficient that thickens that its pipe thickness is compared the straight tube pipe thickness is 1.5.There are big thickness difference in enlarging tube wall and straight tube tube wall, because machine inertia often causes the straight tube distortion of enlarging back segment, cause product bad when moulding.
In addition, the straight tube of accepting the place is also damaged easily, only increases the flared tube wall thickness, can not effectively reduce the disrepair phenomenon that bellows is accepted the place.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of bellows, reduces the product reject ratio to reach, and effectively reduces the purpose of accepting place's cracky phenomenon.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of bellows, comprise body, described body is divided into thickening straight tube, normal straight tube and enlarging, described normal straight tube one end is connected with described thickening straight tube, the other end is connected with described enlarging, and the coefficient that thickens of described normal straight tube tube wall is 1, and the coefficient that thickens of described thickening straight tube tube wall is 1.25, the coefficient that thickens of described enlarging tube wall is 1.5, and described thickening length of straight pipe is greater than described enlarging length.
Preferably, the pipe thickness of described normal straight tube is 10mm, and the pipe thickness of described thickening straight tube is 12.5mm, and the pipe thickness of described enlarging is 15mm.
Preferably, described thickening length of straight pipe is that described enlarging length adds 10 centimetres.
Pass through technique scheme, the enlarging rear end of a kind of bellows that the utility model provides on homogeneous tube is provided with one section thickening straight tube, during the homogeneous tube moulding after the enlarging that processes the pipe thickness maximum, the thickening straight tube that the processing tube wall thickness takes second place carries out the transition to the normal straight tube of pipe thickness minimum at last, and the pipe thickness change procedure is comparatively mild, tube wall is not yielding during moulding, reduced the reject ratio of product, will thicken straight tube during use and be undertaken in the enlarging, the place of accepting is cracky not.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the disclosed a kind of bellows structure schematic representation of the utility model embodiment.
The represented corresponding part title of numeral among the figure:
1, thickening straight tube 2, normal straight tube 3, enlarging
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
According to Fig. 1, the utility model provides a kind of bellows, comprise body, body is divided into thickening straight tube 1, normal straight tube 2 and enlarging 3, normal straight tube 2 one ends are connected with thickening straight tube 1, the other end is connected with enlarging 3, the coefficient that thickens of normal straight tube 2 tube walls is 1, and the coefficient that thickens of thickening straight tube 1 tube wall is 1.25, and the coefficient that thickens of enlarging 3 tube walls is 1.5, thickening straight tube 1 length is greater than enlarging 3 length, preferably, the pipe thickness of normal straight tube 2 is 10mm, and the pipe thickness of thickening straight tube 1 is 12.5mm, the pipe thickness of enlarging 3 is 15mm, and thickening straight tube 1 length is that enlarging 3 length add 10 centimetres.
Enlarging 3 rear ends of a kind of bellows that the utility model provides on homogeneous tube are provided with one section thickening straight tube 1, during the homogeneous tube moulding after the enlarging 3 that processes the pipe thickness maximum, the thickening straight tube 1 that the processing tube wall thickness takes second place, carry out the transition to the normal straight tube 2 of pipe thickness minimum at last, the pipe thickness change procedure is comparatively mild, and tube wall is not yielding during moulding, has reduced the reject ratio of product, to thicken straight tube 1 during use and be undertaken in the enlarging 3, the place of accepting is cracky not.
To disclosed a kind of bellows embodiment's above-mentioned explanation, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
