Hi, this is Chen,
I am using Solidworks 2009. Can someone please teach me how to flatten this loft bend.
I downloaded your file and took a look. Major complicated pc of sheetmetal. GRIN
Did not take the time to see if the flattened part is correct, don't know enough about your design intent.
You used a .5 K-factor which would work fine on a part with that thickness and radius. Soildworks assumes you will be using a punch or a laser to cut the flat pattern so all cuts end up normal to the surface of the flat pattern. This does tend to distort some of the fine features and cuts on the parts. Not much you can do with that.
Figuring out how to form it will be a much bigger issue, you will need to machine a punch allowing for springback and push the part into a urethane pad. Check your sizes and remachine punch to suit.
Not an easy part to make, I wish you luck.
Not quite sure what that part is. Looks like it may be an imported file but it is not sheetmetal so will noty flatten.
You would have to redraw the part as sheet metal and then flatten
Yes, the part was drawn as a loft. I had redraw the part using lofted bends. However, the flat pattern seem incorrect. I attached the latest drawing.
A tip for you, if you often create stamped parts and double curved surfaces you should take a look at a program like "Logopress3" (addin to SolidWorks) where you can flatten parts with bend in bend and double curved surfaces. It also has a strip Layout part and a tool making part. Joust a tip.
Thanks, i will take a look the program.
