Hello,
I want to make a rolled insert with non-penetrating holes (see the example for which I only have the PDF plan but not the original 3D).
So I'm starting from scratch. I draw in 3D the insert whose overall dimensions I know below
I convert it to sheet metal so that I can unfold it and add the holes but here, when I fold it up, the holes are not taken into account.
How to do it?
Hello
For me, it's better to do it flat, pierce it, and then (de)form it.
Hello;
Given the large bending radius and the thickness of the part, to avoid too much deformation of your holes if they are made before bending, I will instead use a 3D sketch in the drilling wizard on the bent component (the question then arises of the need to convert it into sheet metal...)
In general, you should avoid bending in the area that is deforming and in the flat area that is close to the area that is deforming.
The holes on this kind of part deform considerably when they are made on the unfolded part and are found in the folded part afterwards (in the bending radius = deformation)
On this kind of part (stamped or formed more than bent) this is even more true.
Is it really feasible to do the drilling before bending? (ask your folder).
Edit: if it's just for the representation actually like @Maclane drilling with 3D sketch after folding.
I had tried.
The problem is that by doing this, if I specify holes are non-opening, so with a depth dimension lower than the thickness of the sheet, when I unfold the sheet, the holes are indeed present. On the other hand, their shape is ovoid and opening.
So I would like to do the opposite, as I would like to do in real machining. The holes are non-leading to the sheet metal, and then once wound, the holes will have an oval shape.
Yes, it's achievable. We have it on other parts
For me Solidworks can't deform non-cutting holes in a part of sheet metal that is deforming (non-cutting holes have always been systematically removed, it seems to me).
Surely because it is not realistic or too complicated to approach the truth because too many parameters are taken into account.
I strongly advise you to use the drilling wizard instead of material removal for all your types of " holes " intended to receive bolts.
It's not for bolts but plastic filling
Is it possible to create your through-hole holes and then add the material after folding (a sheet with the through holes on the outside + a solid sheet on the inside and then combine the whole?
According to your screenshots, they don't end according to the cone of the drill bit but flat... So it's achievable.
In my mind it doesn't change much and the use of the drilling wizard (yes I insist) will facilitate your drawings.
Note: on the capture of the *.pdf the piercings do not seem distorted...
In this case, what are the differences with this part? And how (and when) were the holes made on the other component?
As said above, the holes are made before rolling.
Unfortunately for me, the original 3D no longer exists and I have to remake this part, almost identical to the example but with a different winding diameter as well as a different sheet thickness as well, hence my request today
… I reiterate my proposal:
I'll try like this
