Abstract
The invention provides a flange leveling mold of an outlet manifold of an automobile exhaust system, aiming at solving the problem that bulges occur on a leveled and machined plane due to a larger area to be leveled and the spring-back influence of materials. The mold comprises an upper mold structure and a lower mold structure, wherein the upper mold structure comprises an upper template; an upper leveling mold is fixed at the lower part of the upper template; the lower mold structure comprises a lower template and a cushion plate; a lower leveling mold is installed on the lower template through the cushion plate; a leveling insert is embedded in the lower leveling mold; the transverse middle part of the leveled plane of the lower leveling mold partially concaves inwards; and the transverse middle part of the leveled plane and the plane at both sides are in arc transition.
Description
Technical field
The present invention relates to the detection frock field of automobile punching parts, be specially the give vent to anger flange leveling mold of manifold of automobile exhaust system.
Background technology
The give vent to anger adpting flange of manifold of a kind of automobile exhaust system; Its structure is seen shown in Figure 1; It need flatten processing to the flange bottom surface, and to wait to flatten area bigger because of its bottom surface, after carrying out disposable punching press leveling processing; The phenomenon that receives horizontal middle part, material springback influence flange baseplane to occur raising up, thus the precision that is connected and installed of flange influenced.
Summary of the invention
To the problems referred to above, the invention provides the give vent to anger flange leveling mold of manifold of automobile exhaust system, it can solve owing to waiting that flattening area leveling processing back plane big, that caused by the material springback influence protruding problem occurs.
Its technical scheme is such, and it comprises mode structure and following mode structure, and the said mode structure of going up comprises cope match-plate pattern; Said cope match-plate pattern bottom is fixed with the leveling patrix; Said mode structure down comprises lower bolster and backing plate, and said lower bolster top is equipped with the leveling counterdie through said backing plate, is embedded with leveling in the said leveling counterdie and inserts; It is characterized in that: the horizontal middle part of the leveling face of said leveling counterdie local indent, the horizontal middle part of said leveling face and plane, both sides arc transition downwards.
It is further characterized in that: the downward indent 0.2mm in horizontal middle part of the leveling face of said leveling counterdie.
Adopt automobile exhaust system of the present invention to give vent to anger behind the flange leveling mold of manifold; Its beneficial effect is: the downward indent in the horizontal middle part of leveling face of its leveling counterdie; And with its plane, both sides arc transition; Make Flange Plane position, intermediate portion when punching press flattens press down certain thickness more, receive the material springback influence after waiting to remove punch press pressure, the material of its horizontal middle part can recoil to and height such as two side planes grade just; Improve the leveling precision effectively, and can improve the precision that is connected and installed of whole flange.
