Description
Technical field
The utility model relates to a kind of metal pipe connection structure, is specifically related to a kind of different kinds of metal tubes structure that is tightly connected.
Background technique
In stainless steel liquid delivery line structure, in order to realize the product lighting, satisfy the needs of energy-saving and emission-reduction, flange can change aluminum alloy material into, like this, has just proposed the problem that Stainless Steel Tube is connected with aluminium alloy flange and guarantees to seal.
The material of flange is an aluminum alloy, in the time of weight reduction, guarantees the intensity of flange again, so need carry out enhancement process to aluminum alloy.The realization Stainless Steel Tube is connected with Al-alloy pipe or flange (through heat treatment reinforcement) and guarantees sealing, does not still have good way at present.Soldering is the way of considering at first, but needs the high temperature heating in the brazing process, thereby the aluminum alloy organization through strengthening is changed, and intensity reduces; Magnetic pulse welding technical sophistication, sealing effect are unstable at present, poor reliability; The sealing effect of screw-jointing method and poor reliability, joint complexity, machining accuracy height; The magnetic pulse formation technology also can realize the connection of different kinds of metal tubes, but can't reach seal request by making the outer tube distortion.
Summary of the invention
The purpose of this utility model is to provide a kind of different kinds of metal tubes structure that is tightly connected, and the sealability between the dissimilar metal pipeline of this structure is good.
Realize the technological scheme of the utility model purpose: a kind of different kinds of metal tubes structure that is tightly connected, it comprises Al-alloy pipe and connected Stainless Steel Tube, is provided with soft metal layer between described Al-alloy pipe and the Stainless Steel Tube.
The end outer surface of aforesaid Al-alloy pipe is circumferentially with two circle Al-alloy pipe grooves along it, soft metal layer inside is stuck in the Al-alloy pipe groove of Al-alloy pipe end outer surface along the two circle soft metal layer boss that it is circumferentially with, the inside of Stainless Steel Tube is circumferentially with two circle Stainless Steel Tube boss along it, and the Stainless Steel Tube boss is stuck in the soft metal layer end outer surface along in its two circle soft metal layer grooves that are circumferentially with; The end outer surface of Stainless Steel Tube is circumferentially with two circle Stainless Steel Tube grooves along it.
Aforesaid soft metal layer can adopt tin alloy or fine aluminium.
The beneficial effects of the utility model are: increase one deck soft metal such as terne metal or fine aluminium between two kinds of metal tubes, as metal packing washer, make the soft metal layer extrusion by the magnetic pulse formation technology, be tightly connected respectively and between Al-alloy pipe and the Stainless Steel Tube, thereby realized being tightly connected between the different kinds of metal tubes.

Among the figure: 1. Al-alloy pipe; 2. soft metal layer; 3. Stainless Steel Tube; 4. magnetic pulse inductor; 5. Al-alloy pipe groove; 6. Stainless Steel Tube boss; 7. soft metal layer boss; 8. soft metal layer groove; 9. Stainless Steel Tube groove.
Embodiment
Below in conjunction with drawings and Examples a kind of different kinds of metal tubes provided by the utility model structure that is tightly connected is described in further detail.
As shown in Figure 1, a kind of different kinds of metal tubes structure that is tightly connected, it comprises Al-alloy pipe 1 and connected Stainless Steel Tube 3, is provided with soft metal layer 2 between Al-alloy pipe 1 and the Stainless Steel Tube 3.The end outer surface of Al-alloy pipe 1 is circumferentially with two circle Al-alloy pipe grooves 5 along it, soft metal layer 2 end internal surfaces are stuck in the Al-alloy pipe groove 5 of Al-alloy pipe 1 end outer surface along the two circle soft metal layer boss 7 that it is circumferentially with, the end internal surface of Stainless Steel Tube 3 is circumferentially with two circle Stainless Steel Tube boss 6 along it, and Stainless Steel Tube boss 6 is stuck in soft metal layer 2 end outer surface along in its two circle soft metal layer grooves 8 that are circumferentially with; The end outer surface of Stainless Steel Tube 3 is circumferentially with two circle Stainless Steel Tube grooves 9 along it.Described soft metal layer 2 can adopt tin alloy or fine aluminium.Al-alloy pipe 1 also can be aluminium alloy flange.
Structure of the present utility model can adopt existing processing method to realize, describes the be tightly connected processing technology of structure of a kind of different kinds of metal tubes below in conjunction with accompanying drawing 2:
(1) end outer surface at Al-alloy pipe 1 processes two grooves 5;
(2) between Al-alloy pipe 1 and Stainless Steel Tube 3, be coated with and apply soft metal layer 2;
(3) the magnetic pulse inductor 4 on the magnetic pulse formation machine is enclosed within Stainless Steel Tube 3 outsides, under the effect of magnetic pulse inductor 4, as shown in Figure 1, Stainless Steel Tube 3 produces its end outer surface of distortion along circumferentially forming two circle Stainless Steel Tube grooves 9 and two circle Stainless Steel Tube boss 6; Stainless Steel Tube boss 6 extruding soft metal layers 2 make its distortion, are extruded its end internal surface of distortion along circumferential formation two circle soft metal layer boss 7 thereby soft metal layer 2 end outer surface are extruded distortion along its circumferential formation two circle soft metal layer grooves 8, internal layer; Thereby the end outer surface of Al-alloy pipe 1 is extruded distortion and circumferentially forms two circle Al-alloy pipe grooves 5 along it; Thereby the realization Stainless Steel Tube is connected and sealing with Al-alloy pipe.
The different kinds of metal tubes provided by the utility model structure that is tightly connected can also be applied to connection and sealing between other different kinds of metal tubes, for example Al-alloy pipe and copper pipe etc.
