extending rectangular tube for laser cutting

[tecpar]

Good morning to all,

I have to realize a structure with a rectangular section tube, with folds at 90° and external bending radius r70 mm. the idea is to do it by single piece, in correspondence of the bendings make a laser cut in order to be able then to fold it by hand and weld it, obtaining the desired radiation (external r70). attached the pipe file. Do you have any idea how to stretch it and make cuts?
in the attached file the internal radius is a consequence of the profile that I have followed to the tube, but I do not care that there is the radius, indeed, I have to get a live edge to weld it

What do you mean, "distender"?

under an image made by the laser cutting program.
with the laser program, I can draw single cuts, and I managed to make the tube as I wanted, but for design needs I should draw it in solidworks.. .
basically, the cut that makes me the laser, leaves me intact a face of the tube, in the image the lower one, which is the external one with the radius r70; then it makes me the cut to "v" that allows me to fold it by hand, getting a live edge inside

 

[MassiVonWeizen]

so is it a request regarding solidworks?
i.e. you're wondering how to make the model in solidworks that then restores the development to give to the laser?

 

[tecpar]

exactly, what I can't do with solidworks is that cut portion that you see in the image that once bent restores me the fold with external radius 70 and internal live edge union to make welding

then I would say that the section "mechanical design" is wrong. there is a section dedicated to solidworks.
do not open a new discussion, but ask the administrators who move this.

I have no idea if that's what you're looking for, but look at this discussion where I made a tube with sheet metal functions

piegatura tubolare tagliato

Buonasera, avrei bisogno di un consiglio. dovrei disegnare un tubolare che viene tagliato a laser per realizzare un paio di fori e dei tagli. Questi ultimi servono per poter lasciare piegare (a mano) il tubolare in quella zona. non riesco a capire come procedere in fase realizzativa...

but how would you do, even in reality, to have an external radius 70mm and inner edge alive?

Here's another one. @tecpar , of the series "thank you thanks and thanks to the ...."

 

[tecpar]

I was on vacation a week... However in reality it has already been done as in the image I have previously attached to the laser program.
good ways accusers anyway @massivonweizen ...

 

[MassiVonWeizen]

if it has already been asked why your question?
If I ask you questions and you are in vacation/impossible you can always write that you will send back, at least avoid that you will sink unnecessarily.
they are not inquisitor, but a bunch of users who volatilize without giving feedback.

 

[tecpar]

It was made in prototypal form, and I have to replicate it in solid, that's all.
I try to see if I can see if anyone has any ideas... Thank you.

 

[MassiVonWeizen]

So the example I posted isn't good or it doesn't help anything, why?

 

[tecpar]

in the example the folds of the tube were made externally but this is the least, I would like to know if with solid, without doing it by hand, you can replicate the cutting profile as above and then spread the tube. it is fine to draw the tube with the functions sheet leaving a cut on one side of the tube, which can be taken at will, and then to extend the "tube" obtained only in the desired folds; I don't know whether there is any way or if there is some plug-ins for solidworks specific to laser cuts
