Shown in accompanying drawing, the basic structure of the integrated pipe of the different material of multilamellar of the present invention and manufacture, application principle.
The present invention is that employing includes integrated by online production equipment making to outer layer mother's pipe 1 and inner-electron pipe 2, its key step
It is: first female pipe 1 is through making in advance or making online, and female pipe 1 sets internal diameter de, and meanwhile, sub-pipe 2 sets outside diameter d n, sub-pipe 2
It is made up of plastic basic unit 21 and solid glue-line 22 and outside diameter d n is slightly larger in dimension than female pipe 1 internal diameter de through online production equipment making
Base substrate 23, sub-pipe 2 is deformed into " U " shape base substrate 23 at base body 23 through online production equipment, and base substrate 23 is online in " U "
Place needle roller 333 when shape type becomes, make needle roller 333 axis be R ° with the drift angle of base substrate 23 axis.
" U " shape base substrate 23 is spaced uniformly to be bundled into by bandage 3 ties up base substrate 23 through tying up operation, ties up base substrate 23 again through fixed
Type operation is processed as base substrate 23 of shaping.Tying up operation is the elastic recovery of base substrate 23 preventing from having diminished.Shaping process be by
The most deformed " U " shape base substrate 23, more chilled equipment carries out freeze settled process, becomes solidification and freezes body.Finally will solidification
Freeze body to insert and add female pipe 1 inner chamber of thermal expansion and integrated.When this conglomerate uses in high temperature or environment of extremely trembling with fear, the factor
Pipe 2 external diameter and female pipe 1 internal diameter are interference fit and intermediate medium is fusible solid glue-line 22, so that sub-pipe 2 is with female
Pipe 1 bonds the most firm, even if they work in high temperature or environment of extremely trembling with fear, still can firmly join between female pipe 1 and sub-pipe 2
Knot and unlikely crack and layering occur.
The integrated pipe of the different material of multilamellar, its outer layer mother's pipe 1 selects metal material or non-metallic material to make.Inner-electron pipe 2 selects
Non-metallic material makes.Base substrate 23, before " U " shape deforms, should be placed in deformation device 4, to base substrate 23 by base substrate 23
Axis, depression bar 332 axis, needle roller 333 axis three are adjusted, install, fix, needle roller 333 axis and sub-pipe body
The drift angle of 23 axis is R °, and R ° of value is 16 °-19 °, and needle roller 333 size is Φ 8-10mm, needle roller 333 in the course of processing
Place elastic recovery properties good after can ensure that the deformation of sub-pipe 2.
Female pipe 1 is cylinder straight tube, this cylinder straight tube or selection metal material cylinder straight tube or selection non-metallic material cylinder straight tube,
Metal material cylinder straight tube preferred cast iron cylinder straight tube.
Because the coefficient of expansion of unlike material is different, both combinations will not occur in order to ensure between mother's pipe 1 of the present invention from sub-pipe 2
There is crack and layering in place.As, when female pipe 1 selects metal material, sub-pipe 2 to select plastic material, the coefficient of expansion between the two
Can be mutually far short of what is expected, or reach 10 times.When the lowest temperature is-52.3 DEG C, its absolute temperature reaches 75 DEG C (room temperature is 23 DEG C).
In order to be used for extremely trembling with fear in environment after making sub-pipe 2 integrated with female pipe 1, therefore require that sub-pipe 2 outside diameter d n is wanted than female pipe 1 internal diameter de
Greatly, the span of ratio between two is 0.675%～0.7%, and the present embodiment takes 0.675%.
Because the coefficient of expansion of unlike material is different, both combinations will not occur in order to ensure between mother's pipe 1 of the present invention from sub-pipe 2
Occur the most how crack and layering, the medium between antithetical phrase pipe 2 outer layer with female pipe 1 inwall select solid glue-line 22 material also to become
The key of the present invention.As, sub-pipe 2 is co-extruded by plastic basic unit 21 and solid glue-line 22, needs consider to have: viscous
The intensity of knot power, the non-sensibility to moisture, excellent stress crack resistance performance and processing characteristics.Solid in the present embodiment
Glue-line 22 material selection DOW Chemical EAA3440 copolymer, it has the heat sealability of excellence and hot sticky performance, particularly when it
The cohesive force of its excellence it is more apparent from when being combined, non-sensibility and the excellent stress cracking resistance to moisture with metal, PE ground.
And under Tao Shi EAA3440 room temperature, it being a kind of graininess, melt flow rate (MFR) is 11g/10min, and elongation at break is 600%, melted
Temperature is 97.8 DEG C, and the highest extrusion temperature reaches 260 DEG C～280 DEG C, and minimum cover thickness reaches 10 μm, and the processing of its excellence is with resistance to
Stress cracking performance, it is particularly suitable for the integrated making of sub-pipe 2 and female pipe 1.
Integration principle: first with high-frequency heating apparatus, mother's pipe 1 is heated to 110 DEG C～120 DEG C, solid gum at 110 DEG C～120 DEG C
Fusing, and plastics fusing point is generally individually higher than 120 DEG C, therefore plastic layer will not occur fusing deformation.Meanwhile, rapidly sub-pipe 2 is coagulated
Admittedly freeze body to insert female pipe 1 inner chamber of having heated and integral.
Shown in accompanying drawing, the base regime of the different material of multilamellar integrated pipe production line.
Production line of the present invention includes that female pipe 1 makes online, and sub-pipe 2 makes online, base substrate 23 deformation in line, sizing and conglomerate
Online making.
