For me, it's a bit complicated things.

Hi all

Here is a drawing which called feeding body.How to create it into 3D model?

Be grateful!

I think you would be better off using 2 revolved conical surfaces rather than a boundary blend as illustrated by a comparison of your curvature plot and the following:

It appears that you have created a blend from the angled edges at the large end to the coplanar edges at the small end; this is going to produce a slight departure from truly conical surfaces as illustrated by your shaded plot. This is critical for your design because you have a conical auger rotating inside. Furthermore, it's likely that you would have trouble converting what you have into an acceptably simple model for rolling the sheet metal into cones.

This forum really isn't the place for us to do full designs for each other. However, looking quickly at your geometry, maybe a couple of snapshots will help you get started.

Create Axis A_1 through DTM1 & DTM2, DTM4 through A_1 at an angle to DTM1, A_2 through DTM4 & DTM3, revolved surface on DTM4, mirror about DTM2, and Merge the two surfaces.
