Help calculating force required to flange a cylinder

AI Thread Summary
Calculating the force required to flange a cylinder outward by approximately 5mm involves understanding the cylinder's diameter, wall thickness, and material type, which can be either aluminum or mild steel. The material's yield strength and the friction between the press die and the metal are crucial for accurate calculations. Additionally, the temperature of the material—whether hot or cold—affects the force needed. Providing a drawing of the flange can clarify the requirements further. Overall, the discussion emphasizes the importance of these factors in determining the necessary force for the flanging process.

Welcome to PF.

What do you mean by "flange a cylinder outwards"?
Maybe a drawing might help.

Do you think the cylinder diameter, or the wall thickness, might influence the force required?

Will the material be hot or cold?

Welcome! :cool:

Do you know how to calculate the cross-section area of metal that needs to be taken to the plastic condition at once, including the stretching of the forming flange?

If you do, the rest of the calculation should only need knowing the yield strength of the material, and assuming the amount of friction between the press die and the flowing metal.

Hello,

Here are some drawings of the flange required. Material is cold.
Aluminum - 1mm thick
or MS - 0.50mm thick.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
