Filed:

Aug 28, 2003

Appl. No.:

10/650630

Inventors:

Stephen T. Cook - Bellbrook OH, US
Mark F. Broerman - Kettering OH, US
Dale R. Conley - Bellbrook OH, US

Assignee:

Dayton Systems Group, Inc. - Miamisburg OH

International Classification:

B21D 51/38

US Classification:

72334, 72337, 72339, 413 23, 413 56

Abstract:

A method and apparatus for forming container ends includes tooling which forms dome members for can ends, which dome members include an open neck thereon. Thread lugs are formed as integral spaced apart shaped protrusions from the neck exterior. A system is also disclosed for forming quantities of a specific form of dome members, capable of later attachment to container bodies. A thin metal strip is fed through an array of progressive tooling to form blanks, from which such specific form of dome members are formed. The blanks are produced in the metal strip and connected thereto by multiple carrying strips which allow sufficient mobility of the blanks with respect to the strip to achieve precise alignment with the tooling at different stations in the progression. At the final station, completed dome members are separated from the remaining metal skeleton and moved rapidly out of the system, and the skeleton may be chopped up for recycling. Those specific dome members may be attached to a container body in a subsequent operation.

International Classification:

B21J 11/00

US Classification:

7240513, 72361, 72426, 72428

Abstract:

Transfer apparatus and method are provided from first (A, A) to second (B, B) stations of tooling in a cap () making press. This cap is biased against the first upper tools by a first airstream () introduced under the cap and moves upward with the first station punch (). As the punch approaches its top location, a transfer airstream () begins while the first airstream is still on, and moves the cap out through a transfer chute () to the second station. The cap departs the chute and passes detents () on a pair of closed retention fingers () which define an extension of the transfer path from the chute into the open second station tools. A vacuum () applied to a port in the second station punch then holds the cup against the rising upper tools. When the punch clears the closing fingers and approaches its top location, an ejection airstream () commences to propel the finished cup via a discharge chute ().

Abstract:

Thread lug forming systems form thread lugs () on container necks or necked end domes. A continuously rotating cam system () has multiple sets of thread lug forming tools () which are driven to recirculate about stationary cams (). The cams actuate inner and outer forming tools () of the tool sets as they progress around the cams to form the thread lugs. A second system uses generally the same tool sets in a multiple-station reciprocating press (), and the container bodies are indexed through the tool stations () in which the thread lugs are formed.
