Abstract
Official abstract text for this publication.
The present invention relates to a tail trim assembly of an exhaust pipe for a vehicle of which shape is simplified to reduce the number of portions and process is changed to simplify processes so that manufacturing cost is reduced and productivity and quality are improved, and a method of manufacturing the tail trim. According to the present invention, a tail trim of an exhaust pipe for a vehicle includes a first tail trim portion of which one end is attached to an exhaust pipe at the rear portion of a vehicle, and a second tail trim portion that has an inner diameter increased in a streamlined shape toward the outside and is integrally formed with the other end of the first tail trim portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a tail trim of an exhaust pipe for a vehicle, the method comprising: forming a substantially tubular pipe section by a pipe forming process; forming a first tail trim assembly along the pipe section by a primary hydroforming process by injecting fluid into the pipe section at high pressure, the first tail assembly including first and second tail trim portions; performing a heat treatment process in the first tail trim assembly,…
