Apparatus And Method For Annealing Container Side Wall Edge For Necking
US Patent:
6349586, Feb 26, 2002
Filed:
May 15, 2000
Appl. No.:
09/571007
Inventors:
Dean Lee Johnson - Littleton CO
Terre Reingardt - Broomfield CO
Terre Reingardt - Broomfield CO
Assignee:
Ball Corporation - Broomfield CO
International Classification:
B21D 4104
US Classification:
723421, 413 69
Abstract:
The trimmed edge of a drawn and ironed aluminum alloy container body is heated to provide a substantially circumferentially uniform profile in the region adjacent an open end, prior to necking of such region. The temperature profile is sufficient to provide the region to be necked with an annealing temperature, preferably involving a temperature, at the trimmed edge, up to about 550 F. or more, before partial cooling. Annealing in this fashion is believed to improve formability in such a fashion that tensile and yield strength progressively increasing during the necking operations.
Method For Necking A Metal Container Body
US Patent:
5448903, Sep 12, 1995
Filed:
Jan 25, 1994
Appl. No.:
8/186760
Inventors:
Dean Johnson - Littleton CO
Assignee:
Ball Corporation - Muncie IN
International Classification:
B21C 3702, B21D 2200
US Classification:
72 94
Abstract:
The method for necking a metal container body comprises the steps of reducing a first portion of the sidewall of the container body to a first necked diameter, applying force to create tension in at least a portion of a second portion of the sidewall, and further reducing the first portion of the container body to a second necked diameter, during at least a portion of the applying step, by effecting relative motion between the container body and an external forming member. The step of applying a force to create tension in the sidewall may comprise radially displacing at least part of the shoulder portion outwardly away from the central longitudinal axis. Such radial displacement may entail positioning a first rotatable support member inside the container body with a forming radius of the support member longitudinally positioned to be misaligned with the shoulder radius of the container body, and moving the support member radially outwardly away from the central longitudinal axis until at least a portion of the shoulder portion is displaced radially outwardly.
Method For Necking A Metal Container Body
US Patent:
5138858, Aug 18, 1992
Filed:
Jul 1, 1991
Appl. No.:
7/723957
Inventors:
Dean Johnson - Littleton CO

William J. Thomas - Thornton CO
Assignee:
Ball Corporation - Muncie IL
International Classification:
B21D 4104
US Classification:
72 68
Abstract:
The present invention is directed to a novel processing for necking metal container bodies. The process comprises die-necking a container body to a first necked plug diameter, employing one or more operations, and thereafter spin-flow necking the container body to a second reduced plug diameter. The utilization of die-necking advantageously reduces plug diameter variability, thereby enhancing and complimenting the spin-flow necking operation.
