Description
Technical field
The present invention relates to automobile exhaust field, relates in particular to a kind of improvement preparation method with regard to muffler.
Background technology
Automotive muffler is an important component part of automobile exhaust system, can reduce automobile exhaust by silencer
The noise of system, and high-temperature gas is smoothly discharged.The material of silencer is selected, structure design and its production technology and excessively program control
The quality of system produces important impact to its quality assurance, cost control, service life etc..Mobile muffler of the prior art
Always it is easily damaged in the case of HTHP, service life is shorter.
The content of the invention
It is an object of the invention to provide a kind of improvement preparation method with regard to muffler, solves noise reduction of the prior art
The detection method of device product is relatively simple or detection just directly use, causes the quality of muffler produced relatively low, service life
Shorter problem.
The present invention is achieved through the following technical solutions：
A kind of improvement preparation method with regard to muffler, the step of including following order：
Step one, get the raw materials ready：Prepare tubing of the wall thickness for 1.2mm, and using pipe cutting machine by the pipeline section of tubing cut growth 30cm；
Step 2, expander：The mouth of pipe for cutting is widened using pipe expander；
Step 3, freezing：Pipeline section is kept in the environment of minus 20 degrees using household freezer for 12 hours；
Step 4, bend pipe：Pipeline section after freezing is bent using bending machine, bent angle radian is 90 ~ 120 °；
Step 5, welding：The silencing pot of shaping is arranged in bend pipe using welding machine；
Step 6, surface treatment：First the surface of bend pipe is polished, then dust is blown off using air gun, then primer spray
And finish paint, baking vessel is sent into after spray is good and toasted 30 minutes at a temperature of 200 degree, toasted rear cooling shaping；
Step 7：Detection：The noise reduction bend pipe of shaping is first carried out into pressure test, vibration-testing is then carried out again, is finally carried out again
High temperature resistant is tested.
Further, the present invention is maximum thes improvement is that：Increase to finished product after muffler makes and is completed
Pressure test, vibration-testing, high temperature resistant test, to simulate environment of the muffler in real work, detect muffler resistance to compression,
Antivibration, high temperature resistant situation.
Described pressure test is, by the noise reduction bend pipe of shaping under the pressure of 200KPa, to continue 2min, detects weld
Can or can not leak air.Further, there is part silencer that solder skip, pore, overlap, slag inclusion and burning occurs in manufacturing process
The weld defect such as wear, this part can be detected by naked eyes, but if carry inside weld pore or it is thin stitch, visually without
Method direct detection is detected to which it is necessary to pass through pressure test, because pore is under the effect of the pressure, muffler is suppressing work
Can burst apart as pore or thin seam can expand with.
It is that 60Hz～200 Hz, vibration acceleration be in vibration frequency by the noise reduction bend pipe of shaping that described vibration-testing is
Under conditions of 98m/s2, time of vibration is 10h, detects the stability of muffler.Further, vehicle exhaust is vented when discharging
Pipe can produce vibration, can detect that muffler can or can not be burst apart or be occurred in the case where long-time is vibrated through the vibration-testing of the present invention
Other problemses.
Described high temperature resistant test is that the noise reduction bend pipe of shaping is toasted 3 minutes at a high temperature of 700 degree, and detection noise reduction is curved
The heat-resisting quantity of pipe surface paint.Further, protection of the paint on muffler surface to silencing pot, it is necessary to resistant to elevated temperatures work
With so needing to test paint.
The present invention compared with prior art, has the following advantages and advantages：
The noise reduction bend pipe of shaping is first carried out pressure test, Ran Houzai by a kind of improvement preparation method with regard to muffler of the present invention
Vibration-testing is carried out, high temperature resistant test is finally carried out again, is solved the detection method of muffler product of the prior art more
Simple or detection just directly use, causes the quality of muffler produced relatively low, the shorter problem of service life.
Specific embodiment
To make the object, technical solutions and advantages of the present invention become more apparent, with reference to embodiment, to present invention work
Further detailed description, the exemplary embodiment of the present invention and its explanation are only used for explaining the present invention, are not intended as to originally
The restriction of invention.
Embodiment 1：
A kind of improvement preparation method with regard to muffler, including the step of following order：
Step one, get the raw materials ready：Prepare tubing of the wall thickness for 1.2mm, and using pipe cutting machine by the pipeline section of tubing cut growth 30cm；
Step 2, expander：The mouth of pipe for cutting is widened using pipe expander；
Step 3, freezing：Pipeline section is kept in the environment of minus 20 degrees using household freezer for 12 hours；
Step 4, bend pipe：Pipeline section after freezing is bent using bending machine, bent angle radian is 90 ~ 120 °；
Step 5, welding：The silencing pot of shaping is arranged in bend pipe using welding machine；
Step 6, surface treatment：First the surface of bend pipe is polished, then dust is blown off using air gun, then primer spray
