Abstract
The present invention features that the exhaust part of the front silencing pipe is shaped to homogeneously waved edge, the inlet part of the back silencing pipe is hemmed and the end of the front silencing pipe is inserted to the head of the back silencing pipe during assembling for two partition board subassemblies to be pressed in separately from two ends of silencer casing. The method is simple, and the silencer has smooth gas flow and no deformation caused by welding stress.
Description
The present invention relates to the mounting technology that a kind of automotive muffler hush tube is shaped, particularly a kind of triangular shaping mounting technology.
The trim designs of present common automotive muffler hush tube, be to carry out separated type and two kinds of forms of integrated type assembling between a plurality of hush tubes and a plurality of dividing plate, separated type is normally firm with the silencing apparatus and the dividing plate assembling of each part, press-fit in the housing with the silencing apparatus two ends then, shortcoming is to be unfavorable for effectively the gaseous emission in the outlet pipe being controlled, may cause other generating noise because of the randomness of gaseous emission, integrated type then is will put into the assembling earlier of each hush tube in the housing and dividing plate and other sound-absorbing materials firmly, put in the housing then, shortcoming can produce stress when being the welding of silencing apparatus end cap, and the silencing apparatus inside temperature is when reaching higher temperature, can make housing or end cap produce distortion because of the extension of hush tube, so that influence gas device tightness and durability.
The purpose of this invention is to provide the mounting technology that a kind of automotive muffler hush tube is shaped.This technological synthesis above-mentioned separated type form with all-in-one-piece advantage and separate inserting type, overcome the randomness of exhausting air and the Yin Wendu extension that causes hush tube that raises and made housing or end cap produce the shortcoming of being out of shape.
The purpose of this invention is finished in the following way: automotive muffler hush tube shaping mounting technology, mainly be meant the fit that adopts between hush tube and a plurality of dividing plate, its technical characteristics is that the preceding hush tube end with preceding dividing plate assembling is suppressed equally distributed seamed edge on the circumference in reducing, the back hush tube front end flange that is docking with preceding hush tube, end with preceding hush tube during assembling patches the into front end of back hush tube, constitutes and separates the inserting type assembling.
Current hush tube relief opening partly forms in the reducing on press machine by the triangular forming die, suppress equally distributed three seamed edges on the circumference, and maintenance contacts well when three ribs on the hush tube partly dock with the flange of back hush tube suction port front end before allowing.
Adopt this mounting technology method, not only assembling is simple, air-flow is unobstructed, has also eliminated the stress when end cap welds effectively, and can not cause the distortion of silencing apparatus end cap or housing because of the thermal distortion of front and back hush tube.
Fig. 1 adopts the assembling schematic representation that separates inserting type between the hush tube in the silencing apparatus.
Fig. 2 is a hush tube exhaust ports triangular shaping schematic representation before the silencing apparatus.
Should invention below in conjunction with example in detail.As Fig. 1 silencing apparatus inside former and later two hush tubes are arranged, partly pass through the reducing on press machine of triangular forming die at preceding hush tube 1 relief opening, simultaneously suppress three seamed edges that are evenly distributed at preceding hush tube 1 periphery, air inlet parts flange at back hush tube 2, being beneficial to two dividing plate sub-assemblys press-fits from the housing two ends, the end of hush tube patches the into front end of back hush tube before allowing during assembling, three seamed edges 3 of hush tube divide maintenance well to contact with the turn-up portion of back hush tube before allowing, so that will put into the assembling earlier of each hush tube in the housing and dividing plate and other sound-absorbing materials firmly, put in the housing then, fit is simple, be convenient to operation, simultaneously the method is beneficial to effectively the control of gaseous emission in the outlet pipe, eliminates other noises that the randomness because of gaseous emission causes.
Claims (3)
1, a kind of automotive muffler hush tube shaping mounting technology, mainly be meant the fit that adopts between hush tube and a plurality of dividing plate, its technical characteristics be with preceding hush tube (1) the relief opening part of preceding dividing plate assembling, in reducing, suppress all equally distributed seamed edge (3) on the circumference, air inlet parts flange at the back hush tube that docks with preceding hush tube, end with preceding hush tube during assembling patches the into front end of back hush tube (2), constitutes the triangular shaping and separates the inserting type assembling.
2, hush tube shaping mounting technology according to claim 1, it is characterized in that suppressing three seamed edges (3) when preceding hush tube (1) relief opening part forms reducing by the triangular forming die on press machine, three seamed edges are evenly distributed on the periphery of hush tube.
3, hush tube shaping mounting technology according to claim 1 keeps well contacting when three seamed edges (3) of hush tube patch with the turn-up portion branch of back hush tube (2) suction port front end before it is characterized in that.
