Lower cylinder pressure: 0.02Mpa enters next process after size qualification, and at the same time, high-strength alloy aluminium strip is cut by aluminium strip
The setting cutting of side machine, high-strength alloy aluminium strip cutting width require error to be no more than 0.15mm, and bimetallic tube is overhead in aluminium strip at this time
Top, the aluminium strip after sizing cutting form bed by aluminium strip, become cylindrical from initial flush system, while overhead bimetallic tube draws
Enter just in cylindrical aluminium strip, forms seamless cylinder by aluminium strip welding set, while argon arc welding can weld two aluminium strip edges
It is connected in one；
5), undergauge: the aluminium strip approach undergauge set of welding fabrication keeps aluminium strip layer and inner tube gap closer, approach welding
Position bumps detector, then not aluminium strip dragger, aluminium layer surface must not be had damage for approach Kazakhstan；
6), high frequency, baking oven heating: the aluminum pipe approach heating generator come out from dragger, moment strong heating, using
Aluminum pipe heated oven temperature is divided into three sections, and respectively 350 degrees Celsius are tightly combined aluminium strip and inner tube, improves stripping to greatest extent
From power；
7), outer tube squeezes out: aluminum pipe moulds extruder outside direct way after baking oven, four silicon carbides of barrel in extruder
Control is respectively as follows: that an area is 160 DEG C, 2nd area are 190 DEG C, 3rd area are 200 DEG C, 4th area are 220 DEG C, mold at 160 DEG C -260 DEG C
2nd area are divided into, temperature is controlled respectively in 240 DEG C, 265 DEG C, and outer modeling is evenly affixed to aluminum pipe outer circle.Then cooling by way of water tank,
Ink jet numbering machine stamp, traction machine travel, approach production line pathological system operation panel, operation panel are connected with four, front detection device,
Signal can be provided when front occurs abnormal, can be automatically recognized when abnormal position reaches operation panel position, and automatic spray is not
It identifies with color paint, then is cut through air-drying device, by client's production requirement length, carry out outer diameter, internal diameter, whole wall thickness, single layer
Wall thickness, outer examine confirmation, and Cutting Length error is not more than 5MM, enters next process after all items are qualified；
8), peeling: managing the SP of well cutting, and both ends outer layer strips, length 5CM, is packed into crosslinking frame；
9), constant temperature oven is crosslinked: crosslinking time is 40 hours, and straightening after the completion of crosslinking, curvature is less than 5mm；
10), after the secondary cutting by 0.95M-1.15M of length, dust is dried up, after secondary detection, packed products.
The beneficial effects of the present invention are: the plastic-aluminum combined SP pipe of four layers of butt welding that the present invention is prepared, can make new energy

For 2nd area, temperature is controlled respectively in 240 DEG C, 265 DEG C, and outer modeling is evenly affixed to aluminum pipe outer circle, the then cooling, coding by way of water tank
Machine stamp, traction machine travel, approach production line pathological system operation panel, operation panel is with the detection device connection of four, front, currently
Side can provide signal when occurring abnormal, can be automatically recognized when abnormal position reaches operation panel position, and spray different face automatically
Colored paint mark, then cut through air-drying device, by client's production requirement length, carry out outer diameter, internal diameter, whole wall thickness, single layer wall thickness,
Outer examines confirmation, and Cutting Length error is not more than 5MM, enters next process after all items are qualified；
8), peeling: managing the SP of well cutting, and both ends outer layer strips, length 5CM, is packed into crosslinking frame；
9), constant temperature oven is crosslinked: crosslinking time is 40 hours, and straightening after the completion of crosslinking, curvature is less than 5mm；
10), after the secondary cutting by 0.95M-1.15M of length, dust is dried up, after secondary detection, packed products.
2. the preparation method of the plastic-aluminum combined SP pipe of four layers of butt welding of one kind as described in claim 1, which is characterized in that high-intensitive
The specific material of alloy aluminum band is A5052 alloy.
