Embodiment Construction

[0039] A forming process for a heat shield of an automobile engine exhaust system, which adopts a cold stamping forming process, which divides the heat shield of an automobile engine exhaust system into left half shells along the longitudinal centerline of its circular air outlet pipe mouth 10 , the right half-shell 20, the left half-shell 10 and the right half-shell 20 are stamped and formed respectively, and then the stamped left half-shell 10 and the right half-shell 20 are welded into a whole.

[0040] Among them, the stamping process of the left half shell 10 and the right half shell 20 first carries out the stamping and forming process on the left half shell 10 and the right half shell 20, and the forming and arrangement directions of the left half shell and the right half shell are opposite, which can make the stamping During processing, the material plate is evenly pressed, so as to ensure that the left half shell and the right half shell are formed in place, and the pr...

Abstract

The invention provides a forming process of an automobile engine exhaust system heat insulation cover and solves the problems of lower forming quality and high machining cost caused by integral casting and forming currently. The cold stamping machining and forming process is adopted, the automobile engine exhaust system heat insulation cover is divided into a left half cover and a right half cover through a longitudinal central line of an exhausting tube port, the left half cover and the right half cover are stamped and formed respectively, and the stamped and formed left half cover and right half cover are welded integrally.

Description

technical field [0001] The invention relates to the field of processing and forming of auto parts, in particular to the field of stamping and forming of auto parts, in particular to a forming process of a heat shield of an exhaust system of an automobile engine. Background technique [0002] A heat shield 1 for an automobile engine exhaust system, which is a regular circular tube, see figure 1 , the lower end of which is provided with an outlet pipe port 2, and the outer circle is provided with outwardly protruding ribs 3, and a round hole 4 is opened on one side of the outer circle. At present, the heat shield of the exhaust system of an automobile engine is mostly cast in one piece. However, due to the complex structure of the heat shield, it is difficult to cast, the overall appearance quality of the heat shield formed by casting is not high, and there is a problem of high casting and processing costs. Contents of the invention [0003] In view of the above problems, t...
