Abstract

The invention relates to a hollow corrugated pipe with nailheads and a manufacture method for the hollow corrugated pipe with the nailheads. By the aid of the hollow corrugated pipe with the nailheads and the manufacture method for the hollow corrugated pipe with the nailheads, 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. A plurality of T-shaped nailheads are arranged on a wall face of a hollow pipe core, plastic layers are composited on the inner wall and the outer wall of the hollow pipe core with the T-shaped nailheads, the hollow pipe core with the composited plastic layers is spirally overlapped to form the corrugated pipe, and spiral pipe walls which form the corrugated pipe are connected with each other in a melted and sealed manner. The hollow corrugated pipe with the nailheads and the manufacture method for the hollow corrugated pipe with the nailheads have the advantages that a precedent is set for the single-walled hollow corrugated pipe with the nailheads; the strength of the corrugated pipe with the large aperture is improved, the weight of the corrugated pipe with the large aperture is reduced, and the material consumption for the corrugated pipe with the large aperture is reduced; the T-shaped nailheads on a surface of a metal pipe core or a non-metal pipe core can be functioned to fix the plastic layers so as to enable the plastic layers to be firmly and integrally connected with the surface of the metal pipe core or the non-metal pipe core, the corrugated pipe is guaranteed against being layered during usage, and compressive strength of the plastic layers is improved.

Description

A kind of SEMITUBULAR RIVET head bellows and making method

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 SEMITUBULAR RIVET head 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 SEMITUBULAR RIVET head bellows and the making method of heavy caliber bellows material simultaneously again.

Design proposal: in order to realize above-mentioned purpose of design.1, bellows is one of technical characteristics 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.2, being furnished with the design of a plurality of T staple heads on metal die or the nonmetal tube core face, is two of technical characteristics of the present invention.The purpose of doing like this is: owing to be furnished with a plurality of T staple heads on metal die or the nonmetal tube core face; When molten plastic topped during at T staple head; Its T staple head has not only played restraining function effectively to compound plastic layer above that; And this continuously connected fastener will be compounded in metal die or nonmetal tube core plastic layer firmly is connected as a single entity, and prevent its layering.

Technological scheme 1: a kind of SEMITUBULAR RIVET head bellows; Hollow tube core wall a plurality of T staple heads that distribute; The hollow tube core spiral that has composite plastic layer on the hollow tube in-core outer wall of T staple head and have a composite plastic layer is superimposed as bellows, constitutes melting sealed connection between the volute wall of bellows.

Technological scheme 2: a kind of making method of SEMITUBULAR RIVET head bellows; The heavy caliber polyolefin that hollow tube is made through the claimant twine increase the pipe production line in directly distortion on bellow forming and the effect of two corrugated surfaces at bellow forming under behind the composite plastic layer, overlap, form the bellows internal face, and have adhere formation SEMITUBULAR RIVET head bellows outer wall 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 SEMITUBULAR RIVET head 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; The 3rd, metal die or nonmetal tube core face T staple head had both played the effect of fixed plastics layer; Plastic layer and metal die or nonmetal tube core face firmly are connected as a single entity; Guaranteed that bellows in use stratification can not take place, and has improved the compressive strength of plastic layer again.

Embodiment

Embodiment 1: with reference to accompanying drawing 1.A kind of SEMITUBULAR RIVET head bellows; Hollow tube core 2 walls a plurality of T staple heads 4 that distribute; Hollow tube core 2 spirals that have composite plastic layer 3 on hollow tube core 2 inside and outside walls of T staple head 4 and have a composite plastic layer 3 are superimposed as bellows 1, constitute melting sealed connection between the volute wall of bellows 1.Said hollow tube core 2 is metal die or nonmetal tube core, and 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 SEMITUBULAR RIVET head bellows; The heavy caliber polyolefin that hollow tube 2 is made through the claimant twine increase the pipe production line in directly distortion on bellow forming and the effect of two corrugated surfaces at bellow forming under behind the composite plastic layer, overlap, form the bellows internal face, and have adhere formation SEMITUBULAR RIVET head bellows outer wall between the plastic tube wall of hollow tube core 2.Said hollow tube core 2 walls a plurality of T staple heads 4 that distribute.
