Embodiment approach

[0030] figure 1 with figure 2 The first embodiment of the supporting device for the pressure core of the muffler of the present invention is shown, which includes a supporting column 1, a supporting arm 2 and a top core 5. One end of the support column 1 is provided with a cavity 11 for installing the top core 5, and a return spring 6 is provided between the top core 5 and the support column 1. When the return spring 6 is in a normal state, the end of the top core 5 extends out of the cavity 11.

[0031] The supporting arm 2 and the supporting column 1 are hinged through a rotating pin 3, and the supporting arm 2 rotates around the rotating pin 3. A through slot 12 is opened at one end of the support column 1 with a cavity 11, and the rotating pin 3 is arranged in the through slot 12. The support arm 2 is provided with a limiting hole 21, the top core 5 is provided with a track pin 4, and the track pin 4 is slidably arranged in the limiting hole 21. The support arm 2 passes th...

Abstract

The invention discloses a supporting device for muffler core-pressing. The supporting device comprises a supporting column, a supporting arm and a moving part. The supporting arm is hinged to the moving part or the supporting column through a rotating pin. The supporting arm drives the relative supporting column to rotate through the moving part. The supporting arm is provided with a limiting hole. The supporting column or the moving part is provided with a track pin. The track pin is slidably arranged in the limiting hole. According to the supporting device for the muffler core-pressing, deformation of a baffle during core-pressing can be avoided, and disassembly and assembly of the device are convenient.

Description

Technical field [0001] The invention relates to the technical field of muffler production, in particular to a supporting device for a pressure core of a muffler. Background technique [0002] The car muffler is mainly used to reduce the noise generated by the engine of a motor vehicle. The principle is that the car exhaust pipe is composed of two pipes with different lengths. The two pipes are separated and then meet. Due to the difference in length between the two pipes The value is equal to half of the wavelength of the sound wave emitted by the car, so that the two rows of sound waves interfere with each other when they are superimposed to weaken the sound intensity and reduce the transmitted sound, thereby achieving the effect of noise cancellation. The muffler is lined with many mesh metal sound-proof disks. When the exhaust gas enters the muffler from the exhaust manifold, the column airflow is divided through multiple channels, and then the sub-airflows collide with each o...
