Steel pipe is transmitted with the direction of the 4th opening 172.Stretch out when steel pipe is moved to the second conveyer chain 151 by mobile clamping device 120
Time on the fixed cell 152 of the part of the 3rd opening 173, open the 3rd opening 173, make the second conveyer chain 151 by steel pipe market
Solidify to curing oven 170, steel pipe is carried out post bake, obtains composite steel tube.Produce after carrying out post bake answers
Conjunction steel pipe makes the bonding strength increase of the plastic tube in base tube and base tube, and flange increases with the bonding strength of the end face of base tube, same
Time, the coating on base tube surface is less likely to occur to come off, and the structure making composite steel tube is more stable, when it is as water pipe, and lining plastic
The setting of material pipe is more uniform, water can be avoided completely to contact with steel pipe, prevent steel pipe from getting rusty, also avoid water to pollute, and two
The when of being attached between root composite steel tube, the flange of two composite steel tubes contacts, and flange is one-body molded with tube body, its
Better tightness after connecting, the end face of base tube also will not contact with water, can be prevented effectively from the secondary pollution of water, it is ensured that life drink
By the health of water.
When the steel pipe heating of curing oven 170 reaches the required time, the 4th opening 172 is opened, by the second conveyer chain
Composite steel tube is exported by 151, carries out natural cooling.
Utilizing the manufacture system 100 of above-mentioned composite steel tube, the present embodiment also provides for the manufacture method of a kind of composite steel tube, bag
Include following steps:
First obtain steel pipe in plastic pipe sleeve is located at base tube, and make the two ends of plastic tube stretch out base tube, be positioned over first
The part stretching out the first opening 135 of conveyer chain 141, sets preheating furnace 130 temperature as 180 DEG C-200 DEG C, controls the first transmission
Chain 141 is through preheating furnace 130 in 15min-30min, and base tube and plastic tube preheat, and make plastic tube soften, convenient
Follow-up flange step and the carrying out of curing schedule, be provided with plastic cement in plastic tube, after preheating, plastic cement fusing formation is moulded
Material glue-line, plastic tube is adhered to the inwall of base tube by plastic layer.In the present embodiment, plastic tube is vinyl tube.
By the steel pipe flange through preheating furnace 130, flange is that the part stretching out base tube of plastic tube is outwards bent and glued
It is connected to the end face of base tube.Steel pipe is positioned over fixed part 143, and plastic tube softens, manually by the two of plastic tube due to preheating
End is outwards bent to form flange, facilitates the operation of staff, and flange is fixed on the end of plastic tube by the plastics glue-line on flange
Face.
Control the steel pipe after mobile clamping device 120 drives flange to be transferred to spray equipment 160 from the first conveyer chain 141 and enter
Row spraying, after preheating, coating is easily adhered the outer wall in steel pipe, makes to be improved without the spray efficiency of electrostatic gun 200.This
In embodiment, coating is epoxy coating.
Control steel pipe the stretching out from spray equipment 160 to the second conveyer chain 151 after mobile clamping device 120 drives spraying
The part of the 3rd opening 173, sets curing oven 170 temperature as 180 DEG C-190 DEG C, controls the second conveyer chain 151 at 15min-
Composite steel tube is obtained through curing oven 170 in 30min.Steel pipe is carried out post bake solidification so as to get the knot of composite steel tube
Structure is more stable, is coated with epoxy resin thermoset material, by solidification, makes composite steel tube outside composite steel pipe liner vinyl tube
Structure is more stable, and performance more optimizes.
This composite steel tube prepared through above-mentioned manufacture system and manufacture method after testing, meets GB/T28897 2012 and marks
Accurate.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For Yuan, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made,
Equivalent, improvement etc., should be included within the scope of the present invention.
