Abstract
The utility model discloses an engine exhaust flange, including flange body, its characterized in that: flange body is by sheet metal stamping forming, and sheet metal's edge all around turns over to form to positive one side punching press strengthens a bounding wall, and strengthen the bounding wall and enclose a fusiformis space that to have upper and lower circular arc and push up, sheet metal's centre is equipped with the flange hole, and the edge all around in flange hole turns over to positive one side punching press and forms a punching press turned welt, the punching press turned welt highly be greater than the height of strengthening the bounding wall, mounting hole about position that sheet metal is close to upper and lower tip is equipped with, upper and lower mounting hole is equipped with projection nut in positive position, and projection nut does not highly exceed the height of strengthening the bounding wall, the bottom in punching press turned welt flange hole has the sphere, and the sphere top is upwards turned over a shrink and is formed the flange joint mouth. The utility model discloses simple structure reasonable in design, preparation make things convenient for with low costsly, have the advantage that the exhaust tesistance is low, effectively promote product quality.
Description
Technical field
This utility model relates to the connection member of a kind of automobile engine, is specifically related to the exhaust flange of a kind of automobile engine.
Background technology
Engine exhaust flange is installed on air vent of automobile engine, is the connector connecting air vent of automobile engine with exhaustor, for being got rid of by the waste gas that electromotor produces.The engine exhaust flange of prior art, generally die cast metal part structure, structure is complicated, cost of manufacture is high；And the flange hole of exhaust flange is generally straight tube design, is the most also Taper Pipe design, therefore can there is bigger exhaust resistance, affect product quality.
Summary of the invention
The problem existed in view of currently known technology, the purpose of this utility model is intended to provide a kind of simple in construction low cost reasonable in design, easy to make, has the advantage that exhaust resistance is low, the engine exhaust flange of effective Improving The Quality of Products.
This utility model has adopted the following technical scheme that:
Engine exhaust flange, including flange body, it is characterized in that: described flange body is by sheet metal punch forming, the edge of sheet metal is formed to side, front punching press turnover and strengthens coaming plate, strengthen coaming plate and cross the fusiformis space with upper and lower dome, the centre of described sheet metal is provided with flange hole, the edge of flange hole forms punching press turned welt to side, front punching press turnover, the height of punching press turned welt is more than the height strengthening coaming plate, described sheet metal is provided with upper and lower installing hole near the position of upper and lower end parts, installing hole is provided with project-welding nut at front position up and down, the height of project-welding nut does not exceed the height strengthening coaming plate.
The bottom of described punching press turned welt flange hole has sphere, and sphere top flips up contraction and forms Flange joint mouth.
Described sheet metal uses the 022Cr11Ti material of thickness 2mm.
Use the engine exhaust flange of technique scheme, after appropriate design, directly by sheet metal punch forming, not only ensure that it is installed and used and structural strength, simple in construction, low cost easy to make simultaneously, directly arranges project-welding nut and fixes in the installation of engine exhaust port to be exhausted flange as position of mounting hole；It addition, exhaust flange has spherical transition for the flange hole of aerofluxus, the aerofluxus of electromotor is drawn outward, therefore there is the advantage that exhaust resistance is low, effective Improving The Quality of Products.
Accompanying drawing explanation
This utility model has a drawings described below:
Fig. 1 is top-direction view of the present utility model,
Fig. 2 is the A-A view of Fig. 1.
Detailed description of the invention
nullAs shown in the figure，Engine exhaust flange of the present utility model，Including flange body，Described flange body is by sheet metal 1 punch forming，The edge of sheet metal 1 is formed to side, front punching press turnover and strengthens coaming plate 2，Strengthen coaming plate 2 and cross the fusiformis space with upper and lower dome，The centre of described sheet metal 1 is provided with flange hole 5，The edge of flange hole 5 forms punching press turned welt 3 to side, front punching press turnover，The height of punching press turned welt 3 is more than the height strengthening coaming plate 2，The bottom of described punching press turned welt 3 flange hole 5 has sphere 4，Sphere 4 top flips up contraction and forms Flange joint mouth，Described sheet metal 1 is provided with upper and lower installing hole 7 near the position of upper and lower end parts，Installing hole 7 is provided with project-welding nut 6 at front position up and down，The height of project-welding nut 6 does not exceed the height strengthening coaming plate 2，Described sheet metal 1 uses the 022Cr11Ti material of thickness 2mm.
