Abstract
The invention relates to a hollow corrugated pipe and a manufacturing method thereof. By the aid of the hollow corrugated pipe and the manufacturing method thereof, the strength of the corrugated pipe with a large aperture can be effectively improved, the weight of the corrugated pipe with the large aperture can be reduced, and material consumption for the corrugated pipe with the large aperture can be reduced. The hollow corrugated pipe comprises a corrugated pipe body, plastic pipes with hollow pipe cores are spirally overlapped to form the corrugated pipe body, and pipe walls of the spirally overlapped plastic pipes are connected with each other in a melted and sealed manner. The hollow corrugated pipe and the manufacturing method thereof have the advantages that a precedent is set for the single-walled hollow corrugated pipe, the strength of the corrugated pipe with the large aperture can be effectively improved, the weight of the corrugated pipe with the large aperture can be reduced, and the material consumption for the corrugated pipe with the large aperture can be reduced.
Description
Technical field
The present invention relates to a kind ofly can improve heavy caliber bellows intensity effectively, can alleviate heavy caliber bellows weight again, can reduce a kind of hollow bellows and the making method of heavy caliber bellows material simultaneously again, belong to bellows and make the field.
Background technique
CN201731192U, title " large-caliber double-wall ripple water pipe ", its tube wall constitutes by the inside and outside is two-layer, and its inner tubal wall is smooth, and outer tube wall is trapezoidal corrugated, is provided with stirrup in the cavity between the inside and outside wall, and connects as one at outer wall trapezoidal bottom groove and inwall.Be provided with stirrup in the cavity between this large-caliber double-wall ripple water pipe inside and outside wall; Improved the intensity of water pipe; Compare with the large-diameter steel-plastic waste pipe that generally uses in the existing technology and to have that overall weight is light, cost is low, easy to install and characteristics that cost of production is low.Its deficiency: because the tube wall of bellows is made up of inner and outer wall, the compressive strength of its inwall strengthens through outer wall, and not only weight is big, and raw materials consumption is big, and compressive strength is uneven.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design and a kind ofly can improve heavy caliber bellows intensity effectively, can alleviate heavy caliber bellows weight again, can reduce a kind of hollow bellows and the making method of heavy caliber bellows material simultaneously again.
Design proposal: in order to realize above-mentioned purpose of design.The present invention is on structural design, and bellows is a major technique characteristic of the present invention the design that the plastic tube spiral that has the hollow tube core is formed by stacking.The purpose of doing like this is: it divides body structure with existing double-wall corrugated water pipe by bilayer; Change overall structure into, both escaped to eliminate the inwall in the background technique, integrated the outer wall in the background technique again; Make the ripple tube wall after the integration both have the function of inwall, have the function of outer wall again.Therefore, not only bearing strength is high, low cost of manufacture, and in light weight, greatly reduced raw-material consumption.
Technological scheme 1: a kind of hollow bellows, it comprises bellows, said bellows be formed by stacking on the plastic tube spiral that has the hollow tube core and the tube wall of the plastic tube of spiral stack between melting sealed connection.
Technological scheme 2: a kind of making method of hollow bellows, the heavy caliber polyolefin that hollow tube is made through the claimant twine increase the pipe production line behind the composite plastic layer directly on bellow forming and have that adhere forms the hollow bellows between the plastic tube wall of hollow tube core.
The present invention compares with background technique, and the one, started the precedent of single wall hollow bellows; The 2nd, both improved the intensity of heavy caliber bellows, alleviate heavy caliber bellows weight again, reduce the consumption of heavy caliber bellows material simultaneously again.
Description of drawings
Fig. 1 is the structural representation of hollow bellows.
Fig. 2 is the sectional structure schematic representation of hollow bellows.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of hollow bellows, it comprises bellows 1, said bellows 1 be formed by stacking on the plastic tube that has hollow tube core 23 spirals and the tube wall of the plastic tube 3 of spiral stack between melting sealed connection.Said hollow tube core 2 is metal die or nonmetal tube core., its making method is an existing technology, is not described herein at this.
Embodiment 2: on embodiment 1 basis; A kind of making method of hollow bellows, the heavy caliber polyolefin that hollow tube 2 is made through the claimant twine increase the pipe production line behind the composite plastic layer directly on bellow forming and have that adhere forms the hollow bellows between plastic tube 3 walls of hollow tube core 2.
What need understand is: though above-mentioned to the mentality of designing of the present invention detailed text description of contrasting; But these text descriptions; Just the simple text of mentality of designing of the present invention is described, rather than to the restriction of mentality of designing of the present invention, any combination that does not exceed mentality of designing of the present invention; Increase and modification, all fall in protection scope of the present invention.
Claims (4)
1. hollow bellows, it comprises bellows 1, it is characterized in that: said bellows (1) be formed by stacking on the plastic tube that has hollow tube core (2) (3) spiral and the tube wall of the plastic tube (3) of spiral stack between melting sealed connection.
2. hollow bellows according to claim 1 is characterized in that: said hollow tube core (2) is metal die or nonmetal tube core.
3. the making method of a hollow bellows is characterized in that: the heavy caliber polyolefin that hollow tube (2) is made through the claimant twine increase the pipe production line behind the composite plastic layer directly on bellow forming and have that adhere forms the hollow bellows between plastic tube (3) wall of hollow tube core (2).
