development of sheet metal and folded

[enriazzo99]

good morning to all I would need help to make a calandrated and folded sheet. I should like to ask whether it is possible to make the sheet in question and how to proceed because unfortunately after several tests I cannot achieve. thanks to all in advance

so you can't realize you have to start dividing the tube there must be a cut if you can't make it

Hello, thank you for the answer, what I mean to you is that to realize it I have to make it hypothetically welded on the red line? also making both tinned/rolled sheets?

 

[teseo]

no absolutely I would cut it at 90° and then weld

I know what you mean. that was immediately understood that a sheet should be opened to be a sheet. Maybe I explained badly: what I don't realize is the set of sling and flat flange of a edge in the same piece

 

[teseo]

I tried too I had difficulty according to me you have to do it in two pieces and then join
How did you do with the red line?

 

[MassiVonWeizen]

What you want to do is possible even in the productive reality.
to the maximum you can divide the realization in two parts: first bend to l of the sheet and then displacement, and also in this way I doubt it comes a good job because in the phase of displacement the perpendicular part to the roll would not be controlled, except to use an element of contrast and guide.
in solidworks dubito you can do it, but find out immediately trying to make a loft-lamiera of a profile to l

productively speaking it is more practical to displace the tube and weld a laser cut ring

 

[teseo]

then I did so, some clarifications:

-you have to calculate the degrees well to have the legs folded at 90°
- as you see are two bodies so the development you must then compose you (make the two developments then join them on the obvious table that is a barbaric), solid "can't" to develop two divided bodies, if you join the bodies then can't do the same development.

Hello I hope to have been helpful

It is clear that making such a piece in reality, from a single piece, well here, is not so easy; as the same mass said

using small devices

 

[enriazzo99]

Thank you all for the answers. As Mass says, I agree that productively speaking is unrealizable. But in my case we say that I was interested in having full development then bending it and displacement it will be cabbage of whom duty. I thank especially pose63 that with this subterfuge he gave me a good idea on how to achieve it.

 

[MassiVonWeizen]

then to bend it and to turn it down will be hollow of those who have to

I strongly disagree.

 

[enriazzo99]

I strongly disagree.

I am of your own opinion but it was a customer request, which is the one who produces the piece

there is a fairly simple method to perform this piece.
the development with the joint preferably in the narrowest part of the sheet.
you make the longitudinal and transversal cutting with laser or with manual disc, then you turn off, weld and straighten the two sides that will be folded,
the bending is done by putting on a matrice e punzone to the right or left of the bending machine, the minimum indispensable so that the ring can pass under the prism.
