forming and loss of features

[vogon]

hi, use solidworks 2022 now for a while and only recently I started using the forming tools.

I have a brass disk with some finsI would like to form with a forming tool, so I created a slightly larger punch than the disk, setting the final surface (no faces to be removed)here everything seems in order, but if I stick the punch to the disk, I find myself with a flat disc without cuts, while in my mind I should find the folded wings and the flat center:Where am I wrong? If I try to use the same uncented punch I find myself with this strange figure, in which the part outside the mold remains unmodified and the rest becomes exactly the record first, as if I had created matterGrazie!

not having the file I can not try, but a council, try to make a sheet, do not use size, but create the figure in the design... try the tool and I think it goes.

Hello, thank you for the quick answer but I didn't fix it. I tried both to create the sheet with the command "crea flangetta" and to create an extruded with the sketch already with the final shape and convert it into sheet metal, but applying the punch always get the same result. I'll file here. Thanks again

you can not create a sheet directly from the sketch of the shape as suggested by @sperx ?
you will see that so should work, without flanges and without conversions in sheet metal.
do the star sketch and use it as a base sheet.

I also tried that method: base flange tab with sketch already cutand then applying the punch returns fullI'm missing something. .

 

[Steppermotor]

but for example if you try to "print" a star shape with edges and without any circular trait what happens?

 

[vogon]

il punzone:molded on simple disk:I created matter, because the only disk weighs 13g and the printed 42g

 

[Steppermotor]

wait I explained badly, I try again
the punch should use the circular one but the disk to print should start having a star shape so that the result should be a star-shaped bowl or similar figures.
style a centerpiece, cut the sheet panel with the shape and then make it the bombing with your spherical shell shaped mold.

Same thing

Hi, I've had some time and tried with deformation, the forming tool is not good for this type of processing because it adds or removes non-changeable material. You could also think about it as if it were at print or molding.
cmq the most realistic result I managed to do I hope you go veins.

 

[vogon]

then thank you so much, in fact the result is much more adherent to reality. remains to be understood as solidworks reasoning since despite the flat central part the hole is "arricized". but in the meantime I understood something more about the formation, thank you!
