Abstract
The invention relates to a straight-through metallic plastic composite tube and relative production. Wherein, it is characterized in that: the inner layer of tube is plastic tube, while the outer layer is the metallic tube whose two ends have folded edge; the producing method of same diameter comprises: inserting the plastic tube into metallic tube; then folding the edge of two ends of metallic tube inwards, to be compressed on the end pad of the end surface of plastic tube or directly on the end surface, to combine the plastic and metallic tubes into one whole; the producing method of different diameters comprises: inserting the small metallic tube whose two ends have inward and outward folded edges into the small section of plastic tube; inserting the large metallic tube whose one end has inward folded edge and another end has no folded edge into the large section of plastic tube; then folding the edge of non-folded edge inwards to compress the outward folded edge of small metallic tube, to combine them, and be combined with plastic tube.
Description
Technical field
Having the present invention relates to liner and moulded a kind of pipe fitting of thin wall metal pipeline system---straight-through type thin-walled metal-plastic composite pipe fitting and production method thereof, this pipe fitting is used for the connection that liner is moulded thin wall metal pipeline.
Background technique
Mould in the thin wall metal pipeline system at liner, can be connected with the method for hot melt between pipeline and the pipe fitting.The skin of its pipe fitting has the thin-wall metal containment vessel, and internal layer is the plastic pipe (function of pipe fitting thin-wall metal case is the plastic pipe of protection internal layer, no linkage function) that is connected with pipe hot melting.
The making method that has occurred is: at the metallic case plastic lining, make thin-walled metal-plastic composite pipe fitting.Or with the metal shell that two lobes process, with the plastic pipe hard-pressed bale within it, by welding or other method, the two halves metal shell is connected as a single entity again, make thin-walled metal-plastic composite pipe fitting.
Summary of the invention
Because the pipe fitting geometrical shape of straight-through class is simple, so make the thin-walled metal-plastic composite pipe fitting of straight-through class, more simple and direct method is arranged: the straight-through type thin-walled metal-plastic composite pipe fitting that the present invention relates to, be characterized in: the metal shell of composite tube of metal and plastic is a thin metallic tubd, after will leading directly to the class working of plastics and putting into thin metallic tubd, by simple spinning or additive method, make thin metallic tubd lean on a bit of pipe of port inwardly to turn down, plastic pipe is encapsulated in the metal tube, makes the thin-walled metal-plastic composite pipe fitting of straight-through class.
The invention has the beneficial effects as follows: only need by simple processing, can finish the making of the thin-walled metal-plastic composite pipe fitting of straight-through class, not only greatly reduce the cost of production of straight-through type thin-walled metal-plastic composite pipe fitting, and, quality of processing controlled easily, product appearance is attractive in appearance.

Embodiment
Below, with embodiment the present invention is described in further detail in conjunction with the accompanying drawings:
Fig. 1 represents: pipe fitting is straight-through to be made up of the straight-through thin metallic tubd that reaches of plastics.
The straight-through following steps for manufacturing that Fig. 2 represents: after plastics lead directly to and are inserted in thin metallic tubd, the part that metal tube is grown the straight-through two ends of plastics inwardly turns down, become the port flange and be close to the straight-through both ends of the surface of plastics, promptly finished the straight-through making (the inside turnover of part that metal tube is grown at the straight-through two ends of plastics becomes port surface, can utilize lathe spinning or additive method to finish) of thin-walled metal-plastic pipe fitting.
Fig. 3 represents: the port pad is as the fitting structure of straight-through port face: straight-through, port pad straight-through by plastics and thin metallic tubd are formed.Because when metal tube inwardly turned down, interior turnover width was difficult to do widely, so when the port surface at straight-through two ends requires broad, satisfy the requirement of port width with the port pad.
It is straight-through that Fig. 4 represents, following steps for manufacturing: the plastics that two ends embedded the port pad are straight-through, are inserted in thin metallic tubd.Then the metal tube two ends are grown the straight-through part of plastics and inwardly turn down, become the port pad that the port flange is close to the straight-through two ends of plastics, promptly finished the straight-through making of thin-walled metal-plastic pipe fitting.
Fig. 5 represents the structure that reducing is straight-through: straight-through, a reducing straight-through path section metal shell straight-through by the plastics reducing of reducing and the straight-through big footpath of a reducing section metal shell are formed.A port of the straight-through path section metal shell of reducing has the port flange of inside turnover; There is the flanging of outside turnover the another port.One end of the straight-through big footpath of reducing section metal shell has the port flange of inside turnover, and the other end does not have flange.
The reducing that Fig. 6 represents is straight-through, following steps for manufacturing: earlier the straight-through path section metal shell of reducing is inserted in the straight-through path section of plastics reducing, its flanging is attached on the step surface at the straight-through reducing place of plastics reducing.Again big footpath section metal shell is inserted in the straight-through big footpath section of plastics reducing, then big footpath section metal shell is inwardly turned down at the step place, form flange one---the flange that the reducing place is inside, compress the flanging of path section metal shell, two sections straight-through metal shells of reducing are linked into an integrated entity, finished the straight-through making of reducing.
At Fig. 7---the associated methods of structure, metal shell and working of plastics that the inside and outside silk represented among Figure 14 is straight-through, with lead directly to identical, so repeat no more.
