I have been spent the last 3 weeks working on the discharge, safety guards, etc. I have also seen that others companies use much less structure then our design.
We have formed sheet metal side walls which a) keep material from falling out b) protect the nip points on the load idlers. From what I gather the side walls are not considered in the structural design. I have tried the machinist handbook and my old collage books for calculating the structure of bent sheet metal, but did not produce anything i have confidence in.
Is using the sheet metal as structure in the calcs a useful road to try?
If so, are there any good resources on calculating structural properties of formed sheet metal?
