Richard Dreier - Woodville OH, US

International Classification:

B21D005/14

Inventors:

Nelson Abbey - Monclova OH, US
Richard Dreier - Woodville OH, US

International Classification:

B21D005/14

US Classification:

072/179000

Abstract:

A keyless tooling system for the production of continuous seam-welded tubes is disclosed wherein the tube forming rolls are selectively held in fixed position on supporting spindles by an expandable tapered bushing. The bushing may be caused to move to permit contraction in annular dimension facilitating the removal of the associated forming roll during a mill changeover.

8/976269

Inventors:

Nelson D. Abbey - Monclova OH
Richard L. Dreier - Northwood OH

Assignee:

Abbey Etna Machine Company - Perrysburg OH

International Classification:

B26D 700

US Classification:

83382

Abstract:

A tube cutting apparatus for cutting a continuously fed elongate tube into predetermined lengths including a removable die set which is mounted at an angle to the horizontal and an associated die set changeover table adapted to receive the die set and tilt the same to a horizontal position to facilitate removal thereof and the positioning of a substitute die set.

Appl. No.:

8/387445

Inventors:

Nelson D. Abbey - Monclova OH
Richard L. Dreier - Northwood OH

Assignee:

Abbey Etna Machine Company - Perrysburg OH

International Classification:

B21B 3108

US Classification:

72239

Abstract:

An automated system for exchanging components of a continuous seam-welded tube mill to change from production of one tubular product to another. The components to be changed are mounted upon subbase units adapted to be removably affixed to a fixed mill base. Alternate sets of changeable mill units mounted on duplicate subbase sections are provided for off line tooling change and setup. Changeover modules are automatically conveyed from a tooling storage area to the mill base for automatic changeover. Push-pull units are incorporated in the changeover modules to shift the subbase sections from the mill base to the changeover module and the previously retooled duplicate subbase sections from the changeover modules into operative position on the mill bases.

Abstract:

An automated system for exchanging components of a continuous seam-welded tube mill to change from production of one tubular product to another. The components to be changed are mounted upon sub-base units adapted to be removably affixed to a fixed mill base. Alternate sets of changeable mill units mounted on duplicate sub-base sections are provided for off line tooling change and setup. Changeover modules are provided alongside and spaced from the mill base. Bridging roll units are extendible to span the space between the mill bases and the changeover modules, and push-pull units are incorporated in the changeover modules to shift the sub-base sections from the mill base to the changeover module and the previously retooled duplicate sub-base sections from the changeover modules into operative position on the mill bases.

Appl. No.:

Richard L. Dreier - Northwood OH

Assignee:

Abbey Etna Machine Company, Inc. - Perrysburg OH

International Classification:

B21D 512
B21D 3902

US Classification:

72 52

Abstract:

An assembly for maintaining alignment of a metal strip between successive roll forming means in an apparatus for forming a metal tube is disclosed. The apparatus includes a first set of roll forming means, which form the flat strip of metal into a generally U-shaped cross-sectional configuration, and a second set of roll forming means which form the U-shaped strip into a generally annular cross-sectional configuration. The assembly includes a pair of cylindrical hold down rolls which engage the guide respective marginal edge portions of the U-shaped strip into the second set of roll forming means. The cylindrical hold down rolls are rotatably supported by appropriate shaft means. The end portions of each of the shaft means are supported by vertically adjustable bearing means for adjusting the angular disposition of the shaft and the associated cylindrical hold down roll with respect to the marginal edge portions of the formed strip of metal. Since the distance between each cooperating pair of bearing means changes during the angular disposition of the shaft, at least one end of the bearing means must allow the shaft to slide telescopically therein when the angular disposition of the shaft is changed.
