Hello everybody

I have been searching all over the internet, but I can't find any solution to my problem..

I am looking for a way to design/draw a blank/sheet metal after it has been pressed/stamped. It is a process where a coil of 0.4mm aluminum is pressed between two pressing forms, which create small dimples on the plate.

I have the CAD design of the two pressing forms - a punch (with the pressing dots), and a die with the pressing holes. (See CAD pictures).

In my experience, the punch and die form tools in Creo is creating a surface/geometry identically to the punch/die form. But that is not what I am looking for. In our situation, the punch is only like "stamping/deep drawing" the aluminum down the die - as illustrated in my sketch.

Are there any way to CAD design the geometry of the blank/sheet metal, after it has been pressed?? That would really help us a lot, as we then can design the product directly from the pressing tools, without the need of measuring the product itself afterwards and go backwards.

Have a nice day :)

Nope. Doing that would require a non-linear FEM contact analysis that can include any slippage of material from the edges of the clamping surfaces. In addition, the actual results vary slightly with thickness and hardness variations. Measuring the results and making an approximation will be faster and as accurate.
 
Bonjour à Tous,

Je cherche à concevoir dans créo, en tôlerie emboutissage, épais: 2.3mm un anneau idem qu'une jante de voiture mais avec des replis; voir la capture écran ;
Quelles fonctions puis je utiliser afin d'y arriver ?
Merci.
Bonne journée
