Abstract
The utility model relates to a heat shield structure, which comprises two left and right shield bodies which are symmetrical with each other, wherein the two shield bodies are welded with each other, the shield structure comprises a main body, the left and right sides of the main body are respectively provided with a flanging and an extending edge, the front and back sides of the main body are respectively symmetrically provided with consistent flanging, and the flanging comprises an arc-shaped groove which is in transition with the main body; the turned edges of the left and right cover bodies are butted to form a butt joint part, the extending edges of the left and right cover bodies are mutually lapped and attached to form a lapping part, and a layer of cellucotton is adhered to the inner wall of a main body of the assembled heat shield structure. The structure solves the difficulty that resistance welding equipment cannot perform spot welding in a small space on the inner side of the heat shield; the appearance is beautiful, and spot welding is firm; the structure has only one spot welding process, shortens the production period of products, improves the working efficiency and reduces the cost.
Description
Technical Field
The utility model belongs to the technical field of passenger car exhaust system encapsulation, concretely relates to separate heat exchanger structure.
Background
In the design process of the exhaust system, a user adds a heat shield at the elbow turning part of the exhaust system in order to ensure the performance requirement of the whole vehicle, and because the trend of the exhaust system is limited, the inner side of the heat shield can not be welded by a resistance welding gun by using a traditional heat shield structure.
Disclosure of Invention
The utility model aims at solving the difficult problem that the heat shield is inboard can't use spot welding, accomplishing the bidding of a certain company's export motorcycle type project.
The specific technical scheme is as follows: a heat shield structure is characterized by comprising a left shield body and a right shield body which are symmetrical to each other, wherein the two shield bodies are welded to each other;
the turned edges of the left cover body and the right cover body are butted to form a butt joint part, the extending edges of the left cover body and the right cover body are mutually lapped and attached to form a lapping part, and a layer of cellucotton is adhered to the inner wall of a main body of the assembled heat shield structure.
Further, the flanging and the extending edge are arranged perpendicular to each other.
Further, the length of the overlapping part is 26 +/-1 mm, and the width of the overlapping part is 16 +/-1 mm.
Further, the lap joint portion is fixed by spot welding.
Has the advantages that:
1. the difficulty that resistance welding equipment cannot perform spot welding in a small space on the inner side of the heat shield is solved;
2. the appearance is beautiful, and spot welding is firm;
3. the spot welding process is one to this structure, shortens the production cycle of product, has improved work efficiency, reduce cost.

Detailed Description
The present invention will be further described with reference to the following specific embodiments.
As shown in fig. 1-3, a heat shield structure comprises two symmetrical left and right shields welded to each other, wherein the shield structure comprises a main body 13, and flanges 11 and extending edges 12 are respectively disposed on the left and right sides of the main body 13, and the flanges and the extending edges are perpendicular to each other. The front side and the rear side of the main body are respectively symmetrically provided with consistent flanges, and the front side and the rear side of the main body are respectively symmetrically provided with an arc-shaped groove 14 which is in transition with the main body;
the flanges 11 of the left and right cover bodies are butted to form a butting part,
the left and right cover extensions 12 are attached to each other in an overlapping manner to form overlapping portions 16, and the overlapping portions 16 are fixed by spot welding as shown by the dotted line frame in the figure. The length of the overlapping part is 26 +/-1 mm, and the width of the overlapping part is 16 +/-1 mm.
Spot welding one side of the welding bead, wherein the diameter of each welding spot is 6mm, and the number of the welding spots is 6, so that the welding spots are supplied by assemblies; i assemble the heat shield assembly on the product to complete the welding of the weld bead on the other side.
The inner wall of the main body 13 of the assembled heat shield structure is adhered with a layer of glass fiber cotton 17.
The above-mentioned embodiments are only described for the preferred embodiments of the present invention, but not for limiting the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
