REVOLVED MATTRESS SPRING

236 Views, 7 Replies

I have an application  where  i can use a mattress type spring,what i need to do is show this in a circular form ie round,what i was hoping to do was to use

the sheet metal tool-first to sketch out the profile ie as attachment, and then roll/ bend this around an axis,is this feasable or am i going about this the wrong way.

Ideally the spring section should be round, in this application 3 mm dia.

Any suggestions.

For the profile you have shown in your attachment there are easier ways to do it. I started by drawing a single section in one sketch, then drawing a circle perpendicular to the end of that profile. Then I used the sweep command to create spring and a rectangular pattern to add more sections.

I don't quite follow the part about rolling/bending around an axis. If you provide a sketch or example of what you mean then someone should be able to help out. It could mean modifying what I've posted or maybe doing it a different way. The part I attached is from Inventor 2014.

Thanks for the reply, the actual modeling of the spring and sweeping along the path is reasonably easy ,the problem is revolving or bending this around an axis to form a circular shape.
Perhaps I should just create a sweep path first and then bend around an axis then create a circle to sweep.
Have a look at the attachment,this will show you what I mean.

I would create in finished form to begin with.  Here is a more complex example

Thanks JD
I will have a go,perhaps I can form a small section of the spring and the create a circular patern and join.

Hi Methoni,

That should give you some ideas how to approach the task at hand. Please have a look at the attached (IV 2010) file.

Best Regards,

Igor.
