◆Part Quality: Extremely high requirement for side wall and flange surface

 

Process Background:

The automobile sill reinforcement part is made of high strength steel, and there are many quality issues such as spring back and distortion. This part flange surface is used for the assembly surface, in order to ensure the matching surface, extremely high requirement for side wall and flange surface. The process of this part is first pre-form, then cam restrike, finally pierce-cam pierce. This method can control the flatness of flange surface and the side wall of the spring back, which is conducive to the modification of part quality.

The key point that really affects the spring back amount is the modeling of the part itself. When the spring back amount of the part is large, it is necessary to use the way of spring back compensation to offset the size deviation caused by the spring back. However, when the side wall is modified, the flatness of the bottom surface must be ensured before the side wall spring back can be modified. The solution to the spring back issue of the side wall and flange surface is usually to implement spring back compensation in the flanging and restrike process, and offset the spring back amount by spring back compensation.

 

Advantage:  

We have much rich experience with high tensile steel part and the countermeasure of spring back, also the early time forming simulation for solve part quality such as wrinkle, split, thinning and spring back, ect.

If you have similar parts with spring back issue of flanging and side wall, please don’t hesitate to contact me, and we will be pleased to reply you.
