Description
Technical field:
The utility model relates to the multiple tube process units, what be particularly related to is that the weldering of a kind of metal tube such as steel pipe, aluminum pipe is formed type and formed sandwich layer pipe and outer tube with inside and outside wall at its pipe with polymer-extruded molding mode, utilizes the process units of the compound multiple tube of binding agent and metal tube formation metal tube and polymer.
Background technology:
Sheet metal strip, forming cylindrical tube as steel band and aluminium strip forms compound pipeline complex pipeline with polymer a large amount of technology report and production is arranged, the cylindrical tube of metal tape and formation has very high intensity, but metallic conduit is not corrosion-resistant, thereby for a long time people for corrosion-resistant, reduce polymer that fluid carries coefficient of friction and carry out the compound multiple tube that obtains metal tube and polymer at the inside and outside wall of metal tube and carried out continuous technological development, number of patent application is the technical scheme (scheme 1) of 02117105 " steel-plastics composite pipe production method and equipment "; Number of patent application is the butt welding plastic-aluminum pipe (scheme 2) of Qingtao Chemical Engineering College of 00100702; Number of patent application be 99801833 German overlap welding plastic-aluminum pipe (scheme 3) arranged; Number of patent application is that 200510020523 butt welded seam when the hole pattern steel band welds is protected and placed the metal tube inner chamber to become mandrel layers pipe (scheme 4) sandwich layer pipe extrusion die; The number of patent application of Shi Zhen is that 99112221 porose steel band is shaped to cylindrical tube and is communicated with outer extrusion die and extrusion mechanism, by clamp-oning the device (scheme 5) that the cylindrical tube inwall forms multiple tube by the steel band hole outward.These schemes all provide good implementing method to the production of multiple tube, but also all come with some shortcomings:
Welding that has disclosed metal tube and moulding that scheme 1 is more extensive, but do not disclose metal tube is overlap welding or butt welding, if the metal tube of overlap welding moulding, the pipe that particularly thicker forming strap joint welding connects, tube wall are not round, and ring stress bearing capacity is not high, with the compound back of the polymer mouth of pipe be connected because of metal tube round, connect poor sealing, be unfavorable for that pressure is higher, the multiple tube production that the caliber size required precision is higher.If the metal tube of butt welding moulding just makes smooth welded seam to adopting which kind of solder technology to arrange in pairs or groups, the non-oxidation layer produces, and makes things convenient for polymer or binding agent bonding and good with it moulding and firmly is combined with each other, and does not all have concrete technical scheme report.Scheme 1 for how in the good metal tube of welding, outer wall extrusion molding and composite core pipe and outer tube, particularly the core pipe is to extrude pipe earlier after cooling forming, it is compound with it just to send into inner wall of metal tube, still the die head of coextrusion mechanism also when not closing up as yet, the cylindrical tube soldered is inserted inner wall of metal tube being shaped at metal tube, still adopt other method that die head is inserted in the metal tube, wall is extruded the pipe of melting shape within it, and make it to fit with inner wall of metal tube, melting shape pipe is the bigger pipe of wall thickness diameter particularly, more easily drop and step on sunken, be difficult for inner wall of metal tube compound, in multiple tube cooling forming process, the sandwich layer pipe produces trend and the situation that breaks away from inner wall of metal tube owing to cooling contraction nature can dwindle its external diameter, this will have a strong impact on the quality of multiple tube, and how reply is handled does not all disclose and report but scheme 1 is done these critical technical problems.If the sandwich layer pipe adopts is to extrude earlier that just to send into inner wall of metal tube behind the pipe cooling forming compound with it, scorch the pipe of in type polymer for the high temperature of avoiding soldered, welding this moment its internal diameter of tubular metal tube well is greater than polymer pipe external diameter, if it is compound firm that the two is close to, necessarily needing a cover after the metal tube coated polymer is close to the two to the mechanism of the compression undergauge of metal tube external diameter and sizing to be combined with each other, but scheme 1 does not disclose yet and reports this, extrude earlier with regard to it that just to send into inner wall of metal tube after pipe cooling compound with it, still die head being stretched into the metal tube inner chamber, to extrude melting shape pipe compound with it, for the caliber size, metal tube wall thickness size, also on technical scheme, cut both ways, also will have more technical scheme to remedy and perfect.Such as the multiple tube that adopts aluminium strip and manufacturing than minor diameter, just can adopt and extrude the method for just sending into aluminum pipe inwall compound with it and undergauge and sizing after the pipe cooling earlier, as adopt steel band and make diameter bigger, the multiple tube that bearing capacity is higher needs consideration and improves and adopt another kind of method with regard to obviously not adopting this method.But generally speaking, a kind of method before adopting, relatively largeization of process units produced line length and complicated, and production cost is higher relatively.
The production method of the plastic-aluminum pipe of scheme 2. Qingtao Chemical Engineering College promptly is to extrude pipe earlier just to send into the metal tube inner chamber after cooling forming compound with it, and its deficiency is addressed in detail preceding.
Scheme 4. application numbers are that 200510020523 " steel-plastics composite pipe production method and device " scheme obviously is the compound production at hole pattern steel band and inside and outside polymeric material, be characterized in by having processed the hole of reservation on the sheet metal strip, the polymer of the ectonexine on its wall is connected as a single entity by binding agent and hole, this pipe preferably resolves with the thermoplastic pipe pipe connecting and utilizes each other hot melt or electric heating molten with tube and tube, tube and tube spare connects as one, and be hot melting connection by the multiple tube outer polymeric layer, hole by metal tube connects as one the internal layer polymer layer of multiple tube again, increase bonding strength and sealing property, but owing to have hole on the metal tube, under the situation of higher serviceability temperature, permissible working pressure will be done 40% ~ 70% reduction, though technical scheme that adopts and the application's technical scheme are basic identical, but the application's technical scheme is specially in the metal tube of the butt welding moulding of imperforate sheet metal strip and its, what the polymeric layer on the outer wall was composited can bear more high pressure, can bear the multiple tube of higher serviceability temperature, also the pipeline of promptly in fact being produced with scheme 4 and scheme 5 is different.
