Rolling Sheet Metal Into A Cylinder

Thanks for your time dan.

Rolling sheet metal into a cylinder.

I would be very grateful for any advice or alternative methods that i could use. Inside diameter thickness x 3 1416 length of plate required. Outer diameter t thickness of sheet used. Windseaker1 sorry for being late getting back yes the bend formula works for rolling as well when you roll a plate you are bending it on a large radius the metal still has to shrink on the inside of the neutral line and stretch on the outside to get a finished diameter that you want you have to compensate by adding or subtracting part of the metal thickness from the neutral line.

At jorgenson metal rolling forming we are capable of rolling steel plate and sheet metal to cylinders like these in 10ft long sections. Essentially you should calculate the centerline arc. Outside diameter thickness x 3 1416 length of plate required. To develop the blank flat length for a cylinder rolled from sheet or plate is quite simple.

Pi d 4t. Additional plate may be required depending on the material thickness and the machinery used. It is simply calculated as pi d. I need to bend stainless sheet into a cylinder about 10 inches diameter and about 22 inches high.

These cylinders were rolled to a precise diameter based on our customer s needs and then welded. Try sketch bend or flex feature. I want to effectively roll the sheet up. The perimeter or circumference of a circle is π d where d id the diameter and hence the circumference of your cylinder is π d π 2010 6314 6 mm thus if you take a sheet of metal 6314 6 mm long and roll it into a cylinder the cylinder will have outside diameter of 2010 mm.

Unfold and fold are tools in sheet metal. For bend in sheet metal work it is assumed that the sheet elongates. As a moderately junior blacksmith and a welder of only 3 days i have a lot of experience with rebar and scrap steel and not a lot of experience with stainless sheet metal. I understand that there are other simple ways of creating cylinders but the reason i started like this was because it s easier for me to put holes into a flat surface rather than a curved one.
