Abstract
The utility model provides a warm air pipeline connecting structure of an automobile engine, in order to solve the problems of quality problems and the like due to the fact that after welding, a warm air pipeline connecting structure of an automobile engine in the prior art generates heat distortion and internal stress which have great negative influences on processing and use of warm air pipelines. The warm air pipeline connecting structure of the automobile engine comprises a thin-walled pipe body and a flange, an annular groove is arranged at a port of the flange, the end of the thin-walled pipe body is pressed to be flange-shaped, and size and depth of the annular groove are matched with size and thickness of the end of the thin-walled pipe body. The warm air pipeline connecting structure of the automobile engine has the advantages that the thin-walled pipe body and the flange are not connected in a welding mode, so that negative influences of heat distortion and internal stress on processing and use of warm air pipelines are avoided, and connection quality is improved.
Description
Technical field
The utility model relates to a kind of motor car engine warm braw pipeline interconnection technique, specially refers to a kind of motor car engine warm braw pipeline jointing construction.
Background technique
Motor car engine warm braw pipeline and EGR EGR pipeline adopt thin metallic tubd as transfer conduit usually, usually adopt the method for metal tube and flange plate welding that two thin metallic tubds are linked together at connection part.Because the mode that adopts welding links together thin metallic tubd and flange plate, the high temperature that welding produces is larger on the thin walled tube impact, and the thermal distortion that produces after welding needs part is reprocessed, to guarantee the correct of size.In addition, the internal stress that produces after welding before product uses or in using process, also may produce distortion or break.Obviously, prior art motor car engine warm braw pipeline jointing construction exists thermal distortion and the internal stress that produces after welding, and processing and the use of warm braw pipeline had larger adverse effect, has the problems such as hidden danger of quality.
Summary of the invention
For solving, thermal distortion and internal stress that the welding that prior art motor car engine warm braw pipeline jointing construction exists produces afterwards, processing and use to the warm braw pipeline have larger adverse effect, have the problems such as hidden danger of quality, the utility model proposes a kind of motor car engine warm braw pipeline jointing construction.The utility model motor car engine warm braw pipeline jointing construction comprises thin-walled body and flange plate, port at flange plate is provided with annular groove, Thin wall Pipe with Arc shaped End is pressed into the flange shape, and size and the thickness of the Thin wall Pipe with Arc shaped End of the size of annular groove and the degree of depth and flange shape are complementary.
The useful technique effect of the utility model motor car engine warm braw pipeline jointing construction is mode connecting thin walled pipe and the flange plate that does not adopt welding, and the thermal distortion of avoiding and the internal stress adverse effect to the processing of warm braw pipeline and use has improved quality of connection.
Description of drawings
Accompanying drawing 1 is the three-dimensional front elevational schematic of the utility model motor car engine warm braw pipeline jointing construction;
Accompanying drawing 2 is the A-A cross-sectional schematic in accompanying drawing 1.
Below in conjunction with the drawings and specific embodiments, the utility model motor car engine warm braw pipeline jointing construction is further described.
Embodiment
Accompanying drawing 1 is the three-dimensional front elevational schematic of the utility model motor car engine warm braw pipeline jointing construction, and accompanying drawing 2 is the A-A cross-sectional schematic in accompanying drawing 1, and in figure, 1 is the thin-walled body, and 2 is flange plate.As seen from the figure, the utility model motor car engine warm braw pipeline jointing construction comprises thin-walled body 1 and flange plate 2, port at flange plate 2 is provided with annular groove, thin-walled body 1 termination is pressed into the flange shape, and size and the thickness of the thin-walled pipe end of the size of annular groove and the degree of depth and flange shape are complementary.The utility model motor car engine warm braw pipeline jointing construction has reduced welding process, does not weld the impact of high temperature, reduces thermal distortion, has not also had the burn-through pipe fitting to cause the possibility of leakage.Not only improve manufacturing efficiency, also improved the yield rate of product, reduced failure risk working process entirely for cold working, avoided the generation of weld defects.In addition, the utility model motor car engine warm braw pipeline jointing construction simple in structure reduced the trimming after welding process and welding, improved manufacturing efficiency, reduces the reject rate of product, the high conformity of product, practicability
Obviously, the useful technique effect of the utility model motor car engine warm braw pipeline jointing construction is mode connecting thin walled pipe and the flange plate that does not adopt welding, and the thermal distortion of avoiding and the internal stress adverse effect to the processing of warm braw pipeline and use has improved quality of connection.
