Abstract
The present invention relates to the production of composite aluminium-plastic pipe as one special plastic product. The pipe features that it consists of one inner and one outer plastic pipes with one intermediate butt welded aluminium pipe combined through adhesive. Its production includes the steps of extrusion and cooling setting of inner plastic layer of and cooling outer adhesive and outer plastic layer, blowing to dry, fault detection and others. The production process has the advantages of short process, reasonable design, flame heating without electric power consumption, fast butt welding, etc.
Description
A kind of aluminium butt joint type aluminium-plastic composite pipe and manufacture method thereof, belong to metal tube do not have cutting substantially and with plastics-production particular product technical field, be mainly used in and produce that various diameters give gas, aluminium-plastic composite pipe that solar energy, air-conditioning and hot and cold water pipeline are used.
In the prior art, common aluminium-plastic composite pipe generally all is to be produced by the manufacturing mechanism that German Unic Co. introduces on the present Domestic market.Its aluminum pipe parts are that overlap joint is overlapping mutually after adopting the moulding of aluminium sheet band, and then heating makes overlapped tube wall fusing and one-tenth pipe welded together by mechanical shock with ultrasonic horn.Can only weld the following thin material of 0.3mm in this way, welding speed is slow, and can only produce small-bore (diameter is less than 32mm) tubing, simultaneously because stitch welding makes the tubing physical dimension inaccurate, the tube wall thickness is inhomogeneous, aluminum pipe combines insecure with plastic tube, thereby influences the quality of whole composite pipe.Its production technology is earlier by making device, one that continuous metal plate and belt forms the U-shaped strip that drill jig cover, a locating sleeve and mandrel that passes drill jig cover and locating sleeve that strip is bent into the pipe that the edge overlaps made the metal tube moulding with ultrasonic stitch welding, and then to internal surface extrusion coated one deck plastic materials of this metal tube, last again at outer surface extrusion coated one deck plastic materials of metal tube, therefore this pipe is not composite pipe but plastics coated tube.It is complex manufacturing not only, is awkward, and because the inner wall of metal tube plastic coating is too thin too soft, and plastics combine not firm with metal, easily produces obscission during installation.
The object of the present invention is to provide and a kind ofly can overcome existing various defectives in the prior art comprehensively, process step is few, be convenient to operation, cladding layer by layer from inside to outside, aluminum pipe adopts butt welding, welding speed is fast, can weld wall thickness 0.3～1.5mm, pipe diameter can increase to 120mm, and wall thickness is even, the plastic-aluminum combination is firm, a kind of aluminium butt joint type aluminium-plastic composite pipe and the manufacture method thereof that can produce real aluminium-plastic composite pipe.
According to the characteristics of argon arc welding and the physical property of aluminium sheet band and plastics, at existing questions in the prior art, basic design of the present invention is: pipe plastics and interior binder in extruding respectively with two extruders earlier, form the interior plastic tube of binder in addition through vacuum sizing and cooling again, again with the aluminium sheet band and use argon arc welding machine to cooperate taper sleeve type to pull out pulling shaping butt welding method compound one deck aluminum pipe outside the inner layer plastic tube of above-mentioned tyre binder continuously, be with the plastic outer tube of binder after heating again outside aluminum pipe in compound one deck, three layers of pipe of cladding are bonded into one mutually by binder layer by layer so from inside to outside.
Aluminium butt joint type aluminium-plastic composite pipe of the present invention, constitute by plastic inner pipe 1, interior adhesives layer 2, thin metallic tubd 3, outer adhesives layer 4 and plastic outer tube 5 successively from inside to outside, it is characterized in that its above-mentioned thin metallic tubd 3 of this composite pipe is for having the butt joint type Thin-walled Aluminum pipe that docks straight weld 6.
The manufacture method of above-mentioned aluminium butt joint type aluminium-plastic composite pipe of the present invention, it is characterized in that this method comprises following process steps: pipe plastics and interior binder in extrude respectively with two extruders (1), form the inner layer plastic tube of adhesives layer in addition through vacuum sizing and cooling, (2) the stand-by aluminium sheet band footpath edge cutter of uncoiling butt joint deposit is cut edge, the use argon arc welding machine cooperates tapered sleeve moulding and crawler continuous drawing machine drawing butt welding to be connected into aluminum pipe and is compounded on the outer wall of the inner layer plastic tube of adhesives layer in above-mentioned (1) formed tyre, (3) with fired heater (separate case application utility model patent) heating of the aluminum pipe after compound to above-mentioned (2), (4) outer layer plastic tube of band adhesives layer and being compounded on the above-mentioned aluminum pipe outer wall in the plastics of extruding outer binder and outer tube respectively with other two extruders again form, cool off through water logging (5), wind-force dries up with eddy current testing and is the finished product aluminium-plastic composite pipe.
Advantage of the present invention is: technical flow design is scientific and reasonable, cost of production can descend significantly, aluminum pipe is taked the butt welding of cutting edge, not only welding speed is fast, firm welding, can weld wall thickness 0.3mm～1.5mm, pipe diameter can increase to 120mm, and tube wall thickness uniformity, help the combination with inside and outside plastic tube, compound firmly, integral tube quality height, because sizing is compound layer by layer from the inside to the outside, can not only guarantee that caliber size is accurate, and can also guarantee that the joint can not come off because of the gesture bending can guarantee to install the time.Owing to adopt the flame heating aluminum pipe, can save a large amount of electric energy, so product cost is lower.
Accompanying drawing is one of most preferred embodiment of the present invention, and the bulk shape structure is perpendicular to the axis cross-cutting fault schematic representation of pipe.
Further describe feature of the present invention as follows with most preferred embodiment in conjunction with the accompanying drawings: pipe PE and internal layer polymeric adhesive in extruding respectively with two extruders, form the internal layer PE matter plastic tube of adhesives layer in addition through vacuum sizing and cooling, the stand-by aluminium sheet band of uncoiling butt joint deposit is cut edge through homemade edge cutter then, use argon arc welding machine to cooperate homemade tapered sleeve moulding and crawler continuous drawing machine drawing butt welding to be connected into aluminum pipe and be compounded on the outer wall of internal layer PE matter plastic tube of above-mentioned formed tyre polymeric adhesive layer, again with homemade and separate case application the fired heater of utility model patent to after the aluminum pipe after the compound heating, extrude outer polymeric adhesive and PE matter outer tube plastics respectively with other two extruders, be with the outer layer plastic tube of adhesives layer in forming and be compounded on the above-mentioned aluminum pipe outer wall cooling of process water logging at last, wind-force dries up with eddy current testing promptly to be become from inside to outside successively by plastic inner pipe 1, interior adhesives layer 2, have the butt joint type Thin-walled Aluminum pipe 3 that docks straight weld 6, the aluminium butt joint type aluminium-plastic composite pipe of outer adhesives layer 4 and plastic outer tube 5.
Change as present embodiment:
1, the model of extruder can be selected according to the needs of the product of being produced;
2, the raw material of inside and outside plastic tube and internal and external layer binder and kind can suitably change, as the binder of available crosslinked PE, PVC and other plastic materials and other model or kind;
3, the mode of the cooling of finished product composite pipe, drying, flaw detection can suitably change;
4, aluminum pipe can be replaced by steel pipe, copper pipe or stainless steel and other metal tubes.
