Hello

Could someone tell me how to bend a rod thread with Solidworks? Thank you

Phil

Hello

Could you please put us a screen print of your need?

Look at my tutorial if it can help you.

All you have to do is look at my tutorial from my previous post and adapt it to your needs.

Thank you for your answers.

I will try to present you with the exact project I want to carry out. My problem is not the design of the part but to make the thread appear in the curves.

In one of my tests, the thread disappears with the deform tool and only appears on the straight parts.

Here is the piece in its current state.

I can't show the thread on the curve.

Maybe just adding an appearance (you "just" have to find the one SW uses for the straight parts)

Thank you stefbeno for your answer.

I use annotation/thread representation but it doesn't work for the curved part.

If it's for the drawing, I think you'll have to go through the "hack" box: make a sketch on the view (related to the geometry it will follow if there are modifications).

Hello phillaf33

Bad news and suggestion.

BAD NEWS It also didn't work with SW 's native Thread function for two reasons: the thread can only go straight, and if you replace the guide curve with a spline, it considers it not a cylinder and then it offers you a trip to the Parthenon.

GOOD NEWS: The solutions I see are to make a coil and then remove the material representing the net with a guide line that gives you the shape of your bending curvature. Of course I can already hear the sirens saying that it's heavy ;-) ;-) ;-) Certainly, but it may be the only way.
Another possibility is to make a straight thread (it works) and then use the bending function.

I haven't tried either but it doesn't cost anything to try especially the second one (it's a variant of the hack box proposed by @stefbeno hihihi  Wouarf)

However, we should look at the management of image mapping, which has improved a lot in the 2019 versions. Except that if you don't have the V.2019 then rusk you start back to square one without receiving the bonus.

Kind regards

PS: The best is maybe to make it simpler, you make a thread (or a thread representation on the parts useful for the nuts only and in your MEP you mark a big ATTENTION Threaded rod material of Ø 8. And you trust the demerdologists of the workshop to make the part for you as you wish.

Good evening

AfDB News

This does not work with the bending function because the calculation does not complete after several hours.

The reason is simple: generally speaking, solidworks does not work like stamping or topology optimization software that takes into account  the deformation of the material. Solidworks does not accept material interpenetration, this can be seen in many functions.
This is also why the function with a scan on a coil does not work either because the bending angle is too large.

However, in your case there is a very strong deformation of the threads in the areas of folding greater than 90°: which leads to a very strong deformation, or even a deterioration of the threads in the folding area, which SW obviously does not know how to manage.

So the best solution remains a mix of what has been proposed by @stefbeno by tinkering directly in the MEP and using notations on the material indicating that the whole part is made entirely with a threaded rod.

Kind regards

Hello.

Thank you all for your answers.

I was looking for a simple and easy solution. I see that the problem is more complicated. So we will adopt the simplest solution: "using annotations on the material indicating that the whole part is made entirely with a threaded rod. "

 

Thank you all

Hello

You can maybe make two separate bodies in your 3D, one with the diameter of your threaded rod and a second identical one but with a diameter equal to that of your rod minus the pitch,
in your drawing you choose "Hidden apparent lines" and you edit their appearance as you need,

It's almost the same as making a sketch in your drawing to represent the thread, but it has the advantage of creating less bug in the drawing,

The method that should work is very rough: really do the removal of material by sweeping by making a 'straight' helix on the 2 straight parts and a helical curve that wraps around the handlebar.

You must be able to find old axemble tutorials explaining how to make a spring that is not continuous in shape but that starts with a wire wrapped around a round shape and then gradually squares...

By doing this kind of geometry for the removal of material it should get the result (but in addition you have to manage the orientation of the removal of material in the curved part ...) .

On the other hand, I'm not sure that spending 1 or 2 days modeling the thing is worth it
