Description
Technical field
The present invention relates to a kind of compound conduit pipe, specifically a kind of by steel band and steel mesh or the two compound conduit pipes that strengthen of metal perforated plate, the invention still further relates to the method and apparatus of this conduit pipe of manufacture, and the heterotypic strip of manufacturing it.
Background technique
Feedwater aqueduct is pressure piping, and the pipeline of pure plastic raw material manufacture is usually used in pressurized water transmission.For guarantee that it has suitable intensity and ring stiffness must have enough tube wall thicknesses simultaneously, during manufacture, the raw material consumption of its unit length is just many.Minor diameter pressure piping is meeting in requirement of strength situation, and its ring stiffness (opposing external load ability) meets the demands simultaneously naturally, but major diameter pressure piping, when it meets internal pressure strength, the ability (ring stiffness) of its opposing external pressure is not enough far away.If the anti-external and internal pressure ability (intensity and ring stiffness) that major diameter pressure tube is had meet the demands simultaneously, its wall thickness needs to increase considerably, thereby makes its manufacture cost be difficult to be accepted by market.Although developed in recent years, rank was higher, the better plastic materials of performance, also there is saving the structured wall plastic pressure tube product of the more excellent composite strengthening of raw materials for plastics production, performance in exploitation, but common pure plastic pipe road product specification is only for below 730 millimeters, and representational steel skeleton plastic clad pipe (ZL94104509.9) is as the upgrading products of pure plastic pipe, also can only produce 600 millimeters of following specifications of diameter.Other large diameter composite metal plastic pipe structure also comprises for example CN2882985Y, and it is the entwining tube with the vertical reinforcing rib of steel band reinforcement, but it can only strengthen ring stiffness; CN101943297A for example again, it improves on the basis of CN2882985Y, discontinuous thread or banded reinforcement is set in the tube wall between strengthening rib, but it has also just further strengthened ring intensity, both can not strengthen axial strength, thereby the complete interior ability of pressing of carrying can not be provided.Therefore,, although these two kinds of pipeline configurations can form large diameter pipeline, can only use as waste pipe, and can not as pressure piping, use as ZL94104509.9; For example the pipeline configuration of CN202007929U is in the pipeline outside of ZL94104509.9 structure, to be wound around the pipeline of CN2882985Y structure again, although this pipeline ring stiffness and axial strength all obtain reinforcement, owing to being subject to the restriction of ZL94104509.9 structure cannot manufacture large diameter pipeline; In addition, CN102269298A has proposed the structure that a kind of inner-walls of duct in CN2882985Y structure is wound around viscose fibre reinforcing band, with this structural strengthening ring intensity and axial strength, but two-layer inside and outside this structure one side is not integrated, there is the risk mutually departing from, inner-walls of duct in CN2882985Y structure is wound around the complexity that viscose fibre reinforcing band has increased production process on the other hand, and manufacturing efficiency is relatively low.

In Fig. 6,7, the basic winding process that forms the two reinforced plastic waste pipes 10 of steel band and steel mesh or metal perforated plate is as follows: compound heterotypic strip 11 is at the uniform velocity sent to through the conveying equipment of feeder 49 and pressure roller 48 formations the fixedly helix being linked to be along the groove on a plurality of grooved rollers 47 in " the roller cage " being comprised of framework 45, a plurality of plain-barreled roll 46 and a plurality of grooved roller 47 and moved in a circle, thus spiral winding.Owing to being wound the two reinforced plastic waste pipes 10 of steel band and steel mesh or metal perforated plate, are continuous processes, therefore compound heterotypic strip 11 is constantly sent into from the tangent direction of " roller cage " lower end, and by a special-purpose heating equipment 50, the heating fusing slightly for plastics of two steel meshes or metal perforated plate overlap joint surface will be compounded in before surface, the outer overlap joint with steel band and steel mesh or the two reinforced plastic waste pipes 10 of metal perforated plate, with little extruder 51, to overlap joint surface, extrude the plastics of melting simultaneously, then overlap two overlap joint surfaces also with 58 compactings of adjustable pressure roller, compound heterotypic strip 11 seam of adjacent winding are integral, naturally the two reinforced plastic conduit pipes of steel band and steel mesh or metal perforated plate after cooling, have been formed.
Feeder 49 is comprised of multipair rod, also can be comprised of one group of chain rail.
Heating equipment 50 is the plastics dual-heated to steel mesh or metal perforated plate faying surface and this place by intermediate frequency inductor, also can be with hot air the plastics dual-heated to steel mesh or metal perforated plate faying surface and this place, or the plastics dual-heated of the combination of above-mentioned two kinds of modes to steel mesh or metal perforated plate faying surface and this place, fully to guarantee to overlap the quality of seam.
Describe preferred embodiment of the present invention above, according to instruction those skilled in the art above, can carry out various changes and variation.
For example, replacement form as above-described embodiment, first, second the not steel mesh of composite portion 24,25 or surface recombination one deck plastics of metal perforated plate of compound heterotypic strip 11 in the above-described embodiments, but this composite bed than corresponding upper band basic unit 23, lower band basic unit 21 is thin so that for both reserve the compound space of overlap joint.Like this, the inner die cavity of corresponding composite machine head also will correspondingly change,, upper and lower forming cavity will be wide with steel mesh or metal perforated plate, but there will be a step part, composite portion is not corresponding for first, second of this step part and above-described embodiment, thereby makes the steel mesh at this place or surface recombination one deck of metal perforated plate than the thin plastics of upper and lower band basic unit.Do like this and will make product, manufacturing installation and method become complicated.
In addition also can the serve as reasons wire netting that other metal forms or the steel orifice plate being formed by the steel plate with eyelet of steel mesh or metal perforated plate.
Therefore, for the change obtaining according to disclosed specific embodiment, be all included in concept of the present invention and spirit.
