Description
Technical field
The present invention relates to the double-deck eyelid covering winding steel multiple tube of a kind of multiple tube and combination process, especially one and be combined
Technique.
Background technology
At present, domestic pipeline is widely used the tubing that polythene material is made, and has longer service life and brilliance
Decay resistance, and polyvinyl piping materials adds man-hour without heavy metallic salt stabilizer, and safety non-toxic, simultaneously inside water body
Also algae, antibacterial or fungus growth will not be promoted, the secondary pollution problem of Drinking Water for Residents can be preferably solved, it is ensured that drink
The safe and sanitary of water.
Due to this overall plastic tubing of tubing monoblock type, therefore when satisfied use pressure and ring stiffness require, can be by tubing
Wall thickness thicken, it is relatively big that this results in tubing materials, and overall weight also increases, and the cost of heavy caliber pipe increases, and big mouth
The tubing making apparatus investment in footpath is the biggest.Especially heavy caliber pipe, its circularity ensures relatively difficult, under critical external compressive resistance ability
Fall, it is difficult to commercially accepted.Therefore to solve these problems, and making full use of the advantage of polyvinyl piping materials, someone makees
Improving, composite steel band on tube wall, to increase the anti-pressure ability of heavy caliber pipe.
But easily formed in tubing appearance after composite steel band and convex to form depressed area, banketing easily recessed outside tubing
Falling into district to pile up, and affect the stud at steel band, serious also can extrude the body between two steel bands, weakens the crushing resistance at this position
Energy.
Summary of the invention
The present invention solves existing steel band composite pipe and forms depressed area due to appearance, causes accumulation of banketing, impact pipe
The defect of the stud at material steel band, it is provided that a kind of double-deck eyelid covering winding steel multiple tube and combination process, the stud at steel band
One layer of eyelid covering is set up in outside so that tubing has double-decker, and keeps tubing appearance smooth, will not form depressed area.
This invention also solves steel band in prior art and be compounded to form projection, easily the body between extruding two projections, shadow
The defect of the performance of speaking pipe material, it is provided that a kind of double-deck eyelid covering winding steel multiple tube and combination process, will by the eyelid covering of outer layer
Depressed area between two projections is closed, and does not affect pipe performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of double-deck eyelid covering winding steel multiple tube, bag
Including body, body appearance is formed with upright ribs, and body appearance sets up one layer of eyelid covering, eyelid covering by eyelid covering band with body spiral
Being entwined, the inner surface of eyelid covering is connected with the top of ribs, and the side of eyelid covering band is provided with flanging, and flanging is towards body
Direction bends, and during eyelid covering band spiral winding, flanging is as eyelid covering band lateral support.Body appearance sets up one layer of eyelid covering, such eyelid covering
Forming double-decker with inboard wall of tube body, be upright ribs between eyelid covering and inboard wall of tube body, eyelid covering is by the sky between ribs
Between close, improve the rigidity that winding pipe is overall, increase overall impact resistance, eyelid covering covers outside ribs, can protect
Ribs, when preventing winding pipe from laying, ribs is produced, by clashing into, the rigidity that Bending Influence is overall, and eyelid covering is covered in ribs
Outside, can protect when be filled with steel band inside ribs, especially ribs, can protect steel band, improves steel band and prevents
Corruption；Eyelid covering is to be formed by eyelid covering band spiral winding, so can add in company with body winding and synchronously complete man-hour so that ribs
With eyelid covering hot melt adhesive, it is also possible to existing body is carried out follow-up spiral winding eyelid covering band, it is achieved upgrading；Eyelid covering band side

The ladder overlapping also hot melt up and down being wound around adjacent dual-side is integral.
As preferably, the position that eyelid covering band spiral winding adjacent side connects is in the side position of ribs, flanging with
Ribs is side by side；Or flanging is in the position between two adjacent ribs, the position that eyelid covering band spiral winding adjacent side connects
Putting and avoid ribs, the side of ribs fits with covering belt inner surface.
As preferably, the top of ribs is arranged to odontoid, and the position covering belt inner surface correspondence ribs is provided with
Toothed region, after eyelid covering band spiral winding becomes eyelid covering, the odontoid at ribs top is meshed with the toothed region covering belt inner surface.
As preferably, the odontoid at ribs top is segmental structure, and the toothed region covering belt inner surface is also tied for segmentation
Structure, and both segmental structures are the most corresponding.
As preferably, being installed with steel band inside ribs, the outer side edges of steel band reaches outside ribs top, in this outer side edges
It is arranged at intervals with the protuberance of evagination, between protuberance and illiteracy belt inner surface, forms embedded structure.
The combination process of a kind of double-deck eyelid covering winding steel multiple tube, after pipe forming, eyelid covering band is extruded by extruder
Rear screw is wound into body appearance, is connected by hot melt in eyelid covering band spiral winding between adjacent dual-side, and at connecting portion
The outside of position is extruded by running roller and flattens, eyelid covering band spiral winding middle tube body synchronous rotary, and eyelid covering band spiral winding enters
The linear velocity at position is identical with the linear velocity at this position of body.
As preferably, in body rotary course, the outer side edges position to ribs is thermally formed hot melt shape, eyelid covering band
In winding process, pinch roller is set at the position of eyelid covering band appearance correspondence ribs and compresses；Or at eyelid covering band and ribs
Between position rotation gear is set, by rotating gear, the outer side edges of ribs is extruded in odontoid, eyelid covering band is corresponding
Inner surface is squeezed into toothed region, and in eyelid covering band spiral winding, odontoid engages each other with toothed region.
The invention has the beneficial effects as follows: body appearance sets up one layer of eyelid covering, such eyelid covering and inboard wall of tube body form double-deck knot
Structure, is upright ribs between eyelid covering and inboard wall of tube body, and eyelid covering, by the space-closed between ribs, improves winding pipe overall
