’Petaling’ of a formed tube

[Roxel]

Hi

Could anyone offer advice for the following (read in conjuction with the image below):

I have a tube that is created via 3 stages. Firstly a shape is punched as per stage 1 (with 6 points). This has been created using the normal feature/create/protrusion. At stage 2 the blank is rolled/formed as shown with a slight gap between the two meeting faces (but still forms a true cylindrical shape). This has been created using feature/create/tweak/toroidal bend. Stage 3 however is causing me problems. I want to 'petal' the 'spikes' to the centre, keeping the cross sectional profile with the circumferential radiiasshown (so i dont end up with a perculiar hexagonal shape when looking end-on). I am playing with 'spinal bend' but not 100% sure whether im in the right place...

I want to emulate the method in which the tube is formed in production, rather than cutting a solid to resemble the final article (if this is at all possible).

Any help would be appreciated. By the way im working in dark ages...using Pro/E 2000i !!! The only floating module optionI have is Pro/SURFACE.

Cheers

Search through the sheetmetal postings. This has been discussed and the solved part is available for download.

I only have revision 2000i with a Pro/SURFACE lincence. When creating a part, my only available 'sub-type' is a solid. Composite and sheetmetal are there but do not execute if selected

Roxel,


Without sheetmetal module , I don't think you can be able to emulate the method in which the tube is formed in production, rather than cutting a solid to resemble the final article.


So buy sheetmetal license.

Just a quickie to prove you do not need Pro/SHEETMETAL...the tweak tool is more powerful than people think...The middle protrusion represents a weld and has been done subsequent to the petalling operation
