Cylinder rolling
Thread Content
Does anyone know the formula for calculating how thick of steel plate can be wrapped around a cylinder of a certain diameter, that is, the formula for calculating the cylinder’s radius of curvature?
It’s in the appendix at the back of that standard; I forgot which book it is. It’s just that the steel plate can’t be rolled into a cylinder of whatever small size; there is an algorithm for calculating this
It mainly depends on the rolling capacity of the plate rolling machine
It’s not like that. The sheet can be rolled into a circle after rolling, but cracks appear on the sheet when it is bent too much, and this is not allowed
You can tell just by looking at the processing range of the sheet metal bending machine
It still hasn’t been solved? Urgent! Urgent! Urgent! I’m begging all of you, experts! !
It is to ensure that the sheet material does not bend and fail during winding
If cold rolling isn’t an option, then hot rolling can be used. For small-diameter thick-walled tube sections, segmented hot pressing formation could also be considered
What the original poster is referring to is probably the formula for calculating the yield rate of cold forming, which can be found in Table 4 of Clause 8.1.1 in GB/T150.4-2011.
