development tab fixing by round tube

[orlmarco]

Good morning is the first time I write and I don't know if I'm wrong,
but I'm a bit in the ball because I can't develop some stems on a 20mm sp.1.5mm tube to run them from fold to attach the dwg to how it should come (the red line is the cut and then folded part)

you can give me a tip please

Thank you.

the program I use and solid edge 2021

 

[gerod]

Maybe attach the pdf so who does not have a program to view, can respond. Thank you.

 

[orlmarco]

good morning I also inserted the pdf as a display, thanks

I could tell you to try to do it as a solid part and then convert it into sheet part
but you would have limits probably in development management.

 

[orlmarco]

I should get it from the tube laser of 3 meters and make 2 tabs that bend outside to make lightning, I don't know if I explained well ..
then inside it must pass another tube

 

[orlmarco]

I tried to make it from sheet metal but then I can't bend the lembi like this

 

[Be_on_edge]

you can achieve with a multiple arc profile flap and then add a single flap. the discriminating to work is that the fold is external to the edge.

 

[orlmarco]

but the tabs I have to get from the laser cutting of the tube

I missed this ride. the module development sheet of solid edge does not cover this case directly, you must therefore find a stratagem; I'll give you some proof.

@orlmarco I still haven't figured out how to make that piece.
from a tube you have to get a piece like this?

Keep in mind that I have no idea how the laser tube works.

If that's how I drew it, how's the wing pulled out and pulled straight?

 

[orlmarco]

Good morning, you have two opposite wings as you did if I can ask you can explain it to me please ..
for realization in practice I asked it several times and they answered me that it is from 1.5mm we fold it by hand and then in press ..
I think I'll also have to think of another solution to propose .. I thought of two flats crushed in the center (like the symbol of the omega to understand us )
Thanks again.

 

[Davimont]

This is designed as the right part to understand where you wanted to arrive but it is not developable.

but you spend a development at the car? It seems strange but I repeat that I have never worked on laser tube.
the most correct result according to me is yours in answer 7 but without passing from the sheet.

 

[orlmarco]

hi, in fact for the laser-tube cutting I have to give it a file like re. 7,
but for drawing 3d and assembling everything I should do as your that you had proposed in reply 11.

I can't bend my tabs, but in yours you tell me that it's not developable (by pipe to understand us right)

a beautiful dilemma

Sorry, but I must have missed something.. .
if I make the tube as sheet metal with multiple flap function, with a light of a few tenths, I get a developing sheet
I add a normal digging
I make the function flap and leave on the sides a light of a few tenths and get the tongue, remains to manage the size that covers quadi entirely the cut that can go to attempts or make an equation.
the pipe is however developable.
(I cannot unfortunately attach files)
I think it's a result you've already arrived at... What's missing?

actually does it but with normal digging from error unscrupulous bodiesit does with the size with the problem that the cutting of the development is tilted but this is the least considered that cmq to the laser you will have to decide if on internal or external skins.

 

[Davimont]

mine is made entirely as part in a brutal way,
Extrusion pipe
cut cut
extrusion tongue with already rays in the sketch.

I don't have the file anymore, but it's really 3 operations.

the speech is that then from this you don't pull out your machine file, this is ok only graphically to show the operator how the finished piece should come.

Unfortunately I can't help you otherwise because I don't know what you have to give to the car.

But I'm almost certain that you don't have to give a flat figure like a development to your machine (but I might be wrong) and so I don't understand why to do it in sheet metal and then lay it down.

Perhaps it is better to explain to what final result you want to arrive and see which road to get there.

 

[orlmarco]

I think there's some confusion.

then I laser cutting have to give a tube design with engravings to perform as

then production must only bend the tabs to 90°
Type :
I hope I have clarified
