The invention is characterized in that the housing of the metal tube in complex shape can be divided into components with simple structures, and the joint between each other can be a circle or a line; thereby, each part of the housing of the tube part can be finished by the technical art of stamping tension with an extremely high processing efficiency and can conveniently connect each part as a whole body; simultaneously the invention can also arrange a preformed plastic tube directly in the inner part of the housing of the metal tube part that is divided into a plurality of parts and then connect the housing of the separated thin-wall metal tube parts as a whole body and seal the plastic tube part in the housing. The invention has the beneficial effects that the thin-wall metal tube parts processed by the method have the advantages of high processing efficiency, low cost and good quality.
Description
Technical field
The present invention relates to a kind of thin wall metal casing plastic composite pipe and production method thereof, this pipe fitting is used to serve as a contrast the hot melt of moulding thin wall metal pipeline and connects.
Background technique
The thin-wall metal layer strip off that lining is moulded the thin wall metal pipeline segment port then just can be connected with the method for hot melt between pipeline and the pipe fitting.Mould in the thin wall metal pipeline system at lining, the skin of 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: plastic lining in the metal pipe element of integral body.But the method is because the shell shape complexity of whole metal pipe element, the shell difficulty of processing is very big, and in metal pipe element during plastic lining efficient low, also can shrink after injecting the plastics typing of thin-wall metal pipe, make the plastic pipe of internal layer in thin-wall metal pipe, to become flexible.
Summary of the invention
This pipe fitting that the present invention relates to is characterized in: complex-shaped metal pipe element shell is divided into the member of simple shape, and makes mutual seam be circle or straight line.Thereby not only the each several part of metal pipe element shell can be finished with the technology of the high punching stretch of work efficiency, more can connect easily to be integral body; Simultaneously, also the plastic pipe that is shaped in advance can be placed directly in the inside of the metal pipe element shell that is split up into several parts, again the thin-wall metal pipe shell that separates be connected into integral body, plastic pipe is encapsulated in its inside.
The invention has the beneficial effects as follows: with the thin-walled metal-plastic pipe fitting of the method processing, make efficiency height, processing cost is low, and quality is good.

Embodiment
Below, with embodiment the present invention is described in further detail in conjunction with the accompanying drawings:
Fig. 1 represents: in the port part of moulding the thin-walled metal-plastic pipe fitting that the thin metallic tubd hot melt is connected with lining, following characteristics are arranged: the port of its working of plastics has step, and the segment port in-flanges of its metal shell has encased the step of working of plastics.
Fig. 2 represents: when lining is moulded thin metallic tubd and is connected with thin-walled metal-plastic pipe fitting hot melt, the plastics lined pipe of metal outer is arranged partly, entered in the step that pipe fitting port part metal shell in-flanges encases.Therefore, moulding the thin-wall metal tube end at lining has been peeled off the plastic tube of metal outer and can not exposed.
Fig. 3 represents: the structure of pipe elbow has following characteristics: its shell is made up of pipe fitting body and two sections segment ports.The pipe fitting body is one section bend pipe, and segment port is the straight tube of inside twice flange; The working of plastics of elbow has following characteristics: the port of elbow has step, and intermediate section is a bend pipe, and two is a straight tube.Wherein the outer wall of a straight tube has half to be and the identical curved surface of pipe fitting body bend pipe negative camber.Therefore, when pipe fitting body one end that the termination that working of plastics has a curved surface is syphon shape from shell screws in, can screw out from the other end.Promptly, working of plastics has been packed in the pipe fitting body that is syphon shape by rotation.The outer wall of working of plastics is fluted at the seam crossing of pipe fitting body and two sections segment ports, and this is to isolate working of plastics in order to put sheet metal at groove, makes things convenient for the welding of seam.
Fig. 4 represents: working of plastics screws in pipe fitting that shell is syphon shape after one's death, with being enclosed within the segment port and the seam of pipe fitting body at working of plastics two ends, promptly obtains finished product.
Fig. 5 represents the structure of pipe fitting threeway: the pipe fitting body of shell is by the integral body of being made up of the pipe and the open tube of in-flanges, and open tube two ends ports having pad, port pad are the hollow disk-shaped of interior hole flanging.The port of its working of plastics has step.The seam crossing that the outer wall of working of plastics forms after corresponding to the both sides inclusion working of plastics with open tube is fluted, and this is to isolate working of plastics in order to put sheet metal at groove, makes things convenient for the welding of seam crossing.
Fig. 6 represents: the tee pipe fitting body of the working of plastics threeway being put into shell, the vertical masonry joint seam that its inclusion working of plastics is formed, the pipe end after the spinning seam again makes in the tube wall of pipe end and turns over, push down the port pad that is placed on the working of plastics step surface, promptly finished the making of threeway.
See from the threeway finished product sectional drawing of Fig. 7: encased the threeway shell of working of plastics, its pipe fitting body is by the integral body of being made up of the open tube of the pipe of flange and seam; The port pad at two ends is turned over tube wall and is fixed on the step surface of working of plastics port in the two ends.
Fig. 8 represents: the structure of pipe fitting four-way has following characteristics: the structure of shell is made up of two identical lobe pipe fitting bodies and two port pads, and the pipe fitting body is made up of one section straight tube and semicanal by in-flanges, and the port pad is the hollow disk-shaped of interior hole flanging; The port of working of plastics has step.
Fig. 9 represents: with the vertical masonry joint seam that forms behind the two lobe pipe fitting body inclusion working of plasticss, the pipe end after the spinning seam makes and turns over the pad of pushing down the working of plastics port in the tube wall again, has promptly finished the making of four-way.
Figure 10 represents: three kinds of forms of pipe fitting outer cover port section: a kind of is that twice in-flanges in termination of straight tube is attached to the segment port that the working of plastics step surface becomes; Another kind is with the hollow disk-shaped of interior hole flanging arranged, i.e. port pad is put the port step surface of working of plastics, and spinning straight tube port makes and turns over pipe fixed port pad, formation segment port in the tube wall then; The third, after working of plastics was put into the pipe fitting shell, the double-turnup port pad that is used in endoporus and cylindrical and all has flange was enclosed within the port and the working of plastics step surface of pipe fitting shell, forms segment port.
Figure 11 represents: other three kinds of forms of pipe fitting outer cover port section: a kind of is that the termination in-flanges of straight tube is attached to the segment port that the working of plastics end face forms; Another kind is a spinning straight tube port, makes and turns in the tube wall the port pad---the disk of endoporus is arranged, be fixed on the port surface of working of plastics, form segment port; The third, after working of plastics was put into the pipe fitting shell, usefulness only excircle had the excircle flange port pad of flange to be enclosed within the port and the working of plastics end face of pipe fitting shell, forms segment port.
