Rolling Sheet Metal Into A Cylinder

I would be very grateful for any advice or alternative methods that i could use.

Rolling sheet metal into a cylinder.

Unfold and fold are tools in sheet metal. I want to effectively roll the sheet up. Additional plate may be required depending on the material thickness and the machinery used. Pi d 4t.

Essentially you should calculate the centerline arc. It is simply calculated as pi d. For bend in sheet metal work it is assumed that the sheet elongates. Thanks for your time dan.

Outside diameter thickness x 3 1416 length of plate required. 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. At jorgenson metal rolling forming we are capable of rolling steel plate and sheet metal to cylinders like these in 10ft long sections. I need to bend stainless sheet into a cylinder about 10 inches diameter and about 22 inches high.

But your best option would be to start the part as cylinder make sure you leave a small slit then unfold make the cutout pattern and fold back to get the flat pattern. 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. To develop the blank flat length for a cylinder rolled from sheet or plate is quite simple. These cylinders were rolled to a precise diameter based on our customer s needs and then welded.

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. 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. Hence the corrected value of developed length of sheet which are rolled for circular shape for manufacturing hollow cylinder is taken as. Above are 3 custom rolled cylinders that were rolled using 1 8 thick or 11ga hot rolled steel sheet metal.
