Automobile main muffler partition plate

Abstract

The utility model relates to an automobile main silencer partition plate which comprises a partition plate body, and the partition plate body is provided with an outer ring flanging and a middle flanging hole which are connected with a silencer wrapping cylinder in a welded mode. A plurality of small holes distributed around the middle flanged hole are also formed in the partition plate body; and an anti-reverse notch is formed in the peripheral flange. According to the utility model, the asymmetrical anti-reverse notches are formed on the periphery flanging characteristic, so that the periphery flanging of the part does not have the characteristic of self symmetry. In this way, when the peripheral flange and the wrapping cylinder are welded, the silencing partition plate can be aligned with the notch in the wrapping cylinder, and the possibility that the silencing partition plate and the wrapping cylinder are welded in a wrong direction is eliminated.

Description

Technical Field

[0001] The utility model relates to a main fire partition of an automobile. Background Art

[0002] The main exhaust baffle of a car is used in the exhaust system of the car. The ambient temperature is relatively high, so the material used for this part is SUH439 stainless steel to prevent the parts from corrosion during use.

[0003] The outer periphery of the main combustion partition of the automobile needs to be welded to the external tube. Attention must be paid to the welding direction during the welding. Because the outer peripheral flange is a symmetrical structure, it is not easy to achieve the problem of direction error prevention simply by using the structural characteristics of the outer peripheral flange, which leads to frequent installation errors during the production and assembly process. Summary of the Invention

[0004] The technical solution provided by the utility model is: a main muffler baffle of an automobile, comprising a baffle plate body, the baffle plate body having an outer ring flange and a middle turn-up hole welded to a muffler tube; the baffle plate body is further provided with a plurality of small holes distributed around the middle turn-up hole; and an anti-reverse notch is provided at the outer peripheral turn-up.

[0005] There are four middle turning holes, two of which are respectively arranged at the two ends of the partition body, and the other two are arranged in the middle of the partition body.

[0006] The utility model creates an asymmetrical anti-reverse notch on the peripheral flange feature, so that the peripheral flange of the part does not have its own symmetrical characteristics. In this way, when the peripheral flange and the cladding are welded, the muffler baffle and the notch on the cladding are aligned, eliminating the possibility of the muffler baffle and the cladding being welded in the wrong direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0008] See also Figure 1 The utility model comprises a baffle plate body 1 having an outer flange 2 welded to the muffler casing and a central flange 3. The baffle plate body 1 is densely distributed with a plurality of small holes 4 surrounding the central flange 3, which facilitate gas flow and reduce component weight. An asymmetric anti-rebound notch 5 is provided on the outer flange 2.

[0009] There are four middle turning holes 3, two of which are respectively arranged at the two ends of the partition plate body 1, and the other two are arranged in the middle of the partition plate body 1. The four middle turning holes 3 need to be welded with four small packaging tubes, and the welding must not leak.

[0010] The present invention creates an asymmetrical anti-reverse notch on the peripheral flange, making the peripheral flange of the part not symmetrical. This allows the muffler baffle to align with the notch on the barrel during welding, preventing the muffler baffle from being welded in the wrong direction.
