“V-Form” progressive strip layout with LogoPress

In order to create a “V-Form” progressive strip layout, one where the part is v-formed at the end of the die as the part is cutoff, you must use a split line in the middle of the bend and then you should unbend the part on each side of the split line. That is the key in order to have this v-formed part positioned correctly in relation to the flat blank.

Start with a dumb imported model for example (or of course it could also be a solid model that you’ve create in SolidWorks with SolidWorks features in the tree), with a single 90° bend in it, regardless of where the coordinate system is positioned.

1. Rotate the model using the SolidWorks Move/Copy body feature to rotate the model so that the legs are at a 45° angle relative to the planes.
2. Now insert your split line by showing your temporary axis on the part (View, Temporary Axes) and selecting this temporary axis and one of the faces and Insert, Reference Geometry, Plane and put a plane at a 45 degree angle between these two selections so that it is splitting the radius in the middle. Then Insert, Curve, Split Line to split the face.
3. Then insert a LogoPress Station Mark and name it “010—V-formed down” for example.
4. Then do a LogoPress Unbending by steps to unbend one half of the bend, being careful to select nearest the split line for the first pick so that the split line is the purple edge in the Unbending by steps Property Manager.
5. After this is unbent, unbend the remaining 45 degree bend, again, being careful that the purple edge populated is the one that was the split line.
6. Now do a Move/Copy body to move the flattened part up to where you want die level to be.
7. Then insert another Station Mark and call this one 020—FLAT.

At that point you are ready to start Part preparation before strip starting. Note that if you envision what we just did, and slowly animate the unbending/the v-forming in your mind, the part is down and as it moves up towards die level the part gets unbent equally from both sides of the middle of the bend; precisely what you need for a v-form progressive die.
