blend wall - sheet metal

[kionn]

Hello everyone.. .
Here I am with a new roman:
I have this detail attached that I have to create a mathematical model, similar to make a bending from a sheet thickness 20 mm (creating also development), we say that the piece must be folded and then machined... .
I have a problem where there are curves,
How do I behave?

 

[DANI-3D]

Bye.

material? size?
a thick sheet 20 mm does not bend so easily

 

[kionn]

well this then I see...
Maybe I'll go down to 15.
Iron material
or I have to see with aluminum. .
the size of the element

 

[Prof.]

so at a first analysis it seems to me an undevelopable geometry with sheet metal.
But it could be rebuilt better, depending on how much you have to respect the size of that geomtria.
However, you should be able to spy on it with the command insert > advanced > > > > aggregation of flat surfaces.
if you can attach the pro-e file and don't step it.
Bye.

15 mm is already better, however for a length of about 2500 it always takes a nice bending press.

to realize it there are two methods:

1) Starting from sheet metal, build a flat part in the shape of trapeze and attach the two flangeed sides.

2) Starting from solid, create an extrusion with the shape of the piece, then turn it into sheet metal removing the sides that do not serve.

of course the bending radius is constant on the whole length of the fold.

another question: is it really necessary for the folds to be variable?
a system to develop it in pro/e is located, but to make folds with variable radius on a 20 mm thick you must have a nice tray (I think at least a 600 ton) and build a specific equipment.

 

[maxopus]

I attach a file made with a wall of blend.
you just adjust the sketches of the two sections and you're fine .... the problem will be to make such a piece in reality.
you need above all a specific equipment for variable ray folds.

 

[DANI-3D]

build a specific equipment

very expensive and difficult to achieve. if the radius must be variable and if there were quantities, I would suggest to make a stanpo, while remaining a difficult and honest processing.

maxopus use pro wf3 (I don't see your part)
prof the prt format there is no file in the casket. .
I have to build a shell like that and then the parts I go to work on cam
therefore it must have a similar pattern with supermmetal that varies compared to the base surface around (5-8)mm..
that I recommend then a welded surface and the parts of the rays I go to displace?

here is the basic model

I didn't install the wf3.
do so: you have to use the blend part function.
realize the first section to "u" including rays, commute the section and realize the second "u" including rays (it is like making a normal blend).
Finish the sections, attach thickness and depth.

How many pieces do you have to make of this "robo"?

 

[kionn]

Now I try as you say...
I have to do one.

 

[maxopus]

Then you do it at a constant radius, so that a trapper can do it to you.

Is there any way to develop it outside the sheetmetal?
I think that without constant rays it is difficult, but if the rays were constant you would succeed (always without turning it into sheet)?

Bye-bye.

 

[kionn]

I can't really shape it.

 

[vale61]

I did it as a solid full, I didn't do the "u" as it said maxopus, then I want to make the shell and remove the walls and all the way no problem... but I have no idea how to spy... in the world of pro-and surfaces there will certainly be the way, but I know little about it.
Bye-bye.

 

[DANI-3D]

Excuse me, but I don't understand, but can the rays be constant?

 

[kionn]

Can you show me how you got the mail?
to spy you have to do as says prof.
- control insert > advanced > union flat surfaces.

Give me half an hour and put a pdf.
with the blend wall you can also make it variable.

 

[maxopus]

here is the pdf.
I did it with the wf4, with the wf3 the procedure is identical.
