SHEET METAL TRANSITIONS

SHEET METAL TRANSITIONS

SHEET METAL TRANSITIONS

(OP)
Lee2006 (Mechanical) Mar 16, 2006
I'M TRYING TO USE THE SOLIDEDGE SHEET METAL FUNCTION TO CREATE A SQUARE TO ROUND TRANSITION IN SHEET METAL FROM A 257mm DIA PIPE TO A 330 X 174 RECTANGLE PIPE. I WANT THE WELDMENT TO BE IN 4 QUADRANTS WITH THE SEAMS MEETING THE CORNERS OF THE RECTANGLE OPENING.
SOLIDEGDE LETS ME MODEL IT BUT DOESNT LET ME FLATTEN IT FOR THE PROFILE.
CAN ANYONE HELP PLEASE?

RE: SHEET METAL TRANSITIONS

Can you send me a picture of your model because I'm not sure I understand exacty what you whant with the weldment, then I will model it for you as an example.

RE: SHEET METAL TRANSITIONS

The method you are using creates a distorted surface, which is why it can't be flattened.
Try this method -

1. Create a sketch of 1 quadrant of the circle from 0-90deg. (ie from horizontal axis to vertical axis.
2. Create a sketch of the part of the rectangle in the same quadrant. (ie half the top face and half the side face)
3. Create a lofted flange between the two.

You should now have 1/4 of your transition - and it should flatten.

You will notice that the circular section blends out to the corner and a triangular face forming the sides.
The joint line will be on the flat faces.
