Methods for necking-in sheet metal can bodies |
| abstract |
Die-forming method for forming necked-in flanging metal on a light gauge drawn and ironed can body with a longitudinally extended transition zone between the necked-in portion and the original can body diameter portion while avoiding wrinkling or puckering of the flanging metal. In an initial stage of the die-forming operation, sheet metal contiguous to the peripheral edge is strengthened by turning such edge inwardly about a small radius. The strengthening member formed exerts a lateral restraint during a second stage of the die-forming operation in which the flanging metal and longitudinally extended transition zone are formed. The die-forming operation is carried out from a single end of the can body using a loose fitting inner die which is readily removable from the working end after reducing the diameter of such end. |
