Description
Technical field
The present invention relates to automobile tail pipe liner technical fields, and in particular to a kind of preparation method of automobile tail pipe liner.
Background technology
Automobile exhaust system is located at vehicle bottom, connects engine outlet side and air, and main function is discharge engine
The exhaust gas of generation, reduces noise at purification exhaust gas.And tailpipe is located at the tail end of the exhaust pipe of engine, play discharge tail gas and
The effect of decoration.Motivation tailpipe is commonly connected directly to after the exhaust connection of the outlet side of engine and muffler,
It is and partially visible.In the prior art, tailpipe generally comprises shell and liner, and liner is set in shell, and therebetween one
As fixation is welded to connect by additional connector or welded plate.
The structure of automobile tail pipe liner is generally as shown in attached drawing 6：Generally comprise the liner ontology swelled outward, liner ontology
The left and right sides be provided with installation edge；Traditional preparation process is to use using bulk stainless steel plate as liner raw material, then
It is positioned in drawing die, flanging block is set to be positioned to liner raw material (drawn component) and prevent liner raw material from drawing on drawing die
Displacement during prolonging.Just press the purpose of liner surrounding in advance in order to realize flanging block before drawing, liner raw material has to
Extra flanging is set in the edge of a complete raw material needed for finished product so that flanging block presses；So making one is complete
Whole liner, reuses edger finished product is carried out to trimming one by one and remove four after the completion of needing first to stretch and then stretch
Extra calendering rim charge part, could obtain final products；Since liner after molding is the intermediate three-dimensional objects (attached drawing 6 to arch upward
It is shown), it is extremely difficult, not easy to operate in trimming process, it is easy to leave notch, cause to break entire product mechanical performance
It is bad；And shaving die is also easy to wear, and reduces the service life, and improves mold input cost；In addition, trimming material cannot
It is utilized again, not only causes the waste of material in this way, and complex process is cumbersome, mold setting is more.
