Abstract
The utility model discloses a two bloated copper brazing interfaces are to taking over, first tubular metal resonator and second tubular metal resonator including butt joint each other, the one end of first tubular metal resonator is equipped with bloated oral area, and the diameter of the oral area that should expand is greater than the diameter of second tubular metal resonator, the second tubular metal resonator inserts the oral area that expands forms the welding mouth, bloated oral area includes different location section of diameter and solder flux packing section, the welding ends of second tubular metal resonator inserts fix a position in the section of location, the solder is followed the section is filled to a welding mouthful entering solder flux makes first tubular metal resonator, second tubular metal resonator welded fastening. It can abundant welding to have guaranteed that the section is filled to the solder flux, welds more firmly, and the quality is more even, has reduced the requirement to welding operation person skill level.
Description
Technical field
The utility model relates to soldering tech field, more particularly, relates to the fine weld bond butt tube of a kind of two swollen copper.
Background technology
Soldering adopts to make solder than the low-melting metal material of mother metal, and by weldment and solder heat to higher than solder fusing point, lower than mother metal fusion temperature, utilize liquid solder to soak mother metal, filling play movement also realizes with the counterdiffusion of mother metal phase the method being connected weldment.Brazing deformation is little, joint smooth and beautiful appearance, is suitable for welding component that is accurate, complicated and that be made up of different materials, as honeycomb panel, turbine blade, hard alloy cutter and printed circuit board (PCB) etc.Careful processing and strict cleaning must be carried out to workpiece before soldering, except degreasing and blocked up oxide-film, ensure interface fit-up gap.
Tradition is the docking welding using the existing two sections of copper pipes of single swollen copper brazing cause for gossip, as shown in Figure 1, when welded two sections of copper pipe center lines occur skew not on the same line, welding just there will be uneven welding, soldering opening 4 some places solder is thick, and some places solder is thin, even there will be the situation only having soldering opening 4 surface soldered and inner nothing infiltration solder, when refrigerant pressure increase, this has just become the weak link of butt tube.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provides a kind of welding more firm, quality evenly, reduce the two swollen copper brazing interface butt tube that welding operator's qualification is required.
For achieving the above object, the technical scheme that the utility model provides is as follows: provide a kind of two swollen copper brazing interface butt tube, comprise the first metal tube and second metal tube of docking mutually, one end of described first metal tube is provided with swollen oral area, the diameter of this is swollen oral area is greater than the diameter of described second metal tube, described second metal tube inserts described swollen oral area and forms soldering opening, described swollen oral area comprises the different positioning section of diameter and solder flux filled section, the welding ends of described second metal tube inserts in described positioning section locates, solder enters solder flux filled section from described soldering opening and makes described first metal tube, second metal tube is welded and fixed.
As preferably, in technique scheme, the welding ends of described second metal tube insert in positioning section locate and make described first metal tube, the center line of the second metal tube is located along the same line.
As preferably, in technique scheme, described positioning section and solder flux filled section are one-shot forming.
As preferably, in technique scheme, the diameter of described positioning section is less than the diameter of described solder flux filled section.
Wherein, described first metal tube and the second metal tube are the copper pipe of diameter 6 ~ 20mm.
Compared with prior art, the beneficial effects of the utility model are: a kind of two swollen copper brazing interface butt tube of the utility model, when carrying out swollen mouth to copper pipe, no longer be expanded into the swollen oral area of a diameter, but be expanded into the different positioning section of diameter and solder flux filled section, the welding ends of another copper pipe inserts in positioning section to locate and welds, reduce the requirement to welding operator's qualification, ensure that the center line of two sections of copper pipes can be located along the same line, ensure that solder flux filled section can fully be welded, welding is more firm, quality evenly.
Below in conjunction with drawings and Examples, the two swollen copper brazing interface butt tube of one described in the utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the single swollen copper brazing interface butt tube of tradition;
Fig. 2 is the structural representation of a kind of two swollen copper brazing interface described in the utility model.
Detailed description of the invention
Be below the preferred example of a kind of two swollen copper brazing interface described in the utility model, therefore do not limit protection domain of the present utility model.
Refer to Fig. 2, there is shown a kind of two swollen copper brazing interface butt tube, comprise the first metal tube 1 and the second metal tube 2 of docking mutually, one end of described first metal tube 1 is provided with swollen oral area 3, the diameter of this is swollen oral area 3 is greater than the diameter of described second metal tube 2, described second metal tube 2 inserts described swollen oral area 3 and forms soldering opening 4, described swollen oral area 3 comprises the different positioning section of diameter 31 and solder flux filled section 32, the welding ends of described second metal tube 2 inserts in described positioning section 31 locates, solder evenly enters solder flux filled section 32 from described soldering opening 4 and makes described first metal tube 1, second metal tube 2 is welded and fixed, described positioning section 31 also may enter solder in a small amount.
In an embodiment, described first metal tube 1 and the second metal tube 2 are the copper pipe of diameter 6 ~ 20mm.
During enforcement, the welding ends of described second metal tube 2 inserts in positioning section 31 locates and guarantees that the center line of described first metal tube 1, second metal tube 2 is located along the same line.Ensure that solder flux filled section can fully be welded, welding is more firm, quality evenly, decrease the requirement to welding operator's qualification.
The utility model adopts two swollen copper brazing interface to there is no increase relative to tradition list swollen copper brazing interface production cost, by the improvement of expand tube die head, the positioning section 31 of described swollen oral area 3 and solder flux filled section 32 are still one-shot forming, and the diameter of described positioning section 31 is less than the diameter of described solder flux filled section 32.
Preferably, referring again to Fig. 2, according to the diameter of copper pipe, the gap of solder flux filled section 32 is generally 0.04d ~ 0.07d, the length of described swollen oral area 3 equals the diameter of copper pipe, and 2/3 of swollen oral area 3 leading portion forms solder flux filled section 32, and this is swollen, and 1/3 of oral area 3 back segment forms positioning section 31.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
