Manufacturing device of tail pipe decorative frame body

Abstract

The invention discloses a manufacturing device of a tail pipe decorative frame. The manufacturing device comprises a sharp corner die and a punching die. The sharp corner die is used for carrying outsharp corner die pressing on the round corners of a decorative frame body blank, so that the round corners of the decorative frame body blank are converted into right angles, and a decorative frame body to be punched is formed; and the punching die is used for punching along the straight line included angle and perpendicular to the interior of the decorative frame body to be punched to form the tail pipe decorative frame body. The manufacturing device has the advantages that the round corners are subjected to included angle film pressing through the sharp corner die to form the linear includedangles, then the tail pipe decorative frame body can be machined and manufactured through punching of the punching die, and hole edges of the punched tail pipe decorative frame body do not need to beflanged, Therefore, the phenomena of die marks and edge warping of the punched tail pipe decorative frame body are prevented, the forming quality of the tail pipe decorative frame body is improved, and the manufacturing efficiency of the tail pipe decorative frame body is also improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing a tailpipe decorative frame, in particular to a manufacturing device for a tailpipe decorative frame. Background technique [0002] As we all know, the exhaust pipe is an important part for automobile exhaust, generally including the main body of the exhaust pipe, the exhaust connecting pipe and the tailpipe of the automobile. The decorative tailpipe is exposed, which can not only increase the appearance decoration effect, but also play the role of boosting and turbulence, and reduce the noise from the tailpipe to a certain extent. [0003] The tailpipe of a car is generally composed of an outer tube and an inner tube. The outer tube is a little decorative and is mainly used to protect the inner tube. There needs to be a gap between the inner wall of the outer tube and the outer wall of the inner tube to prevent noise. For example, the Chinese utility model patent publication No. CN20866939...

AI Technical Summary

Problems solved by technology

like figure 1 and figure 2 As shown, rounded corners 13 are formed at the intersection of the first outer part 11 and the first inner part 12 of the decorative frame body blank 1, and the punching direction in the punching process requirements should be perpendicular to the punching plane, but due to the existence of the rounded corners 13, the The punching direction of the decorative frame blank 1 can only be perpendicular to the first interior 12, such as figure 2 The direction indicated by the middle arrow is the punching direction, such as image 3 As shown, the decorative frame blank 1 after punching is obtained, and the rounded corners 13 will still be retained, and then the rounded corners 13 at the junction of the first outer part 11 and the first inner part 12 are formed by hole flanging Figure 4 In the decorative frame 5, but after the hole is flanged, there will be mold marks and warping defects
