Please continue to refer to Figure 10, in the present embodiment, curing oven 170 includes that there is opposite third opening 173 and the 4th to open
Third opening 173 and the 4th opening 172 are stretched out and for along third opening 173 in the both ends of mouth 172, the second conveyer chain 151 respectively
Steel pipe is transmitted with the direction of the 4th opening 172.It is stretched out when steel pipe is moved to the second conveyer chain 151 by mobile clamping device 120
When on the fixed cell 152 of the part of third opening 173, third opening 173 is opened, makes the second conveyer chain 151 by steel pipe market
To being cured in curing oven 170, reheating is carried out to steel pipe, obtains composite steel tube.What is produced after progress reheating answers
Closing steel pipe makes the bonding strength of plastic tube and base tube in base tube increase, and the bonding strength of the end face of flange and base tube increases, together
When, the coating on base tube surface is less likely to occur to fall off, and the structure of composite steel tube is made more to stablize, when being used as water pipe, lining plastic
The setting of expects pipe is more uniform, can completely avoid water and is contacted with steel pipe, prevent steel pipe from getting rusty, also water is avoided to pollute, and two
When being attached between root composite steel tube, the flange of two composite steel tubes is in contact, and flange is integrally formed with tube body,
Better tightness after connection, the end face of base tube will not be contacted with water, can effectively avoid the secondary pollution of water, ensure life drink
With the health of water.
When the steel pipe heating of curing oven 170 reaches the required time, the 4th opening 172 is opened, the second conveyer chain is passed through
151 export composite steel tube, carry out natural cooling.
Using the manufacture system 100 of above-mentioned composite steel tube, the present embodiment also provides a kind of manufacturing method of composite steel tube, packet
Include following steps：
Plastic pipe sleeve is set in base tube first and obtains steel pipe, and the both ends of plastic tube is made to stretch out base tube, is positioned over first
The part of the opening of stretching first 135 of conveyer chain 141, sets 130 temperature of preheating furnace as 180 DEG C -200 DEG C, control first transmits
Chain 141 passes through preheating furnace 130, base tube and plastic tube to be preheated in 15min-30min, and plastic tube is made to soften, convenient
The progress of subsequent flange step and curing schedule is provided with plastic cement in plastic tube, and after preheating, plastic cement melts to form modeling
Expect that glue-line, plastic tube are adhered to the inner wall of base tube by plastic layer.In the present embodiment, plastic tube is vinyl tube.
By across the steel pipe flange of preheating furnace 130, flange is by the part outward bending of the stretching base tube of plastic tube and to glue
It is connected to the end face of base tube.Steel pipe is positioned over fixed part 143, plastic tube is since preheating softens, manually by the two of plastic tube
It holds outward bending to form flange, facilitates the operation of staff, flange is fixed on the end of plastic tube by the plastics glue-line on flange
Face.
The mobile clamping device 120 of control drive the steel pipe after flange from the first conveyer chain 141 be transferred to spray equipment 160 into
Row spraying, after preheating, coating is easily adhered the outer wall in steel pipe, and the spray efficiency of no electrostatic gun 200 is made to be improved.This
In embodiment, coating is epoxy coating.
The mobile clamping device 120 of control drives stretching of the steel pipe after spraying from 160 to the second conveyer chain 151 of spray equipment
The part of third opening 173 sets 170 temperature of curing oven as 180 DEG C -190 DEG C, and the second conveyer chain 151 of control is in 15min-
In 30min composite steel tube is obtained across curing oven 170.By steel pipe carry out reheating solidification, so as to get composite steel tube knot
Structure is more stablized, and composite steel pipe liner vinyl tube applies epoxy resin thermoset material outside, by solidification, makes composite steel tube
Structure is more stablized, and performance more optimizes.
This after testing, meets the marks of GB/T28897-2012 through composite steel tube made from above-mentioned manufacture system and manufacturing method
It is accurate.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
