Reform tub iris to also include coil shear
10773288 · 2020-09-15 · ·

A combined iris and shear unit for a coil forming device is provided that includes an actuator and a plurality of support members coupled together in series to support formation of a coil and connected to the actuator. Each support member further comprises a retractable shear blade. The actuator adapted to cause movement of the support members between an open position with the blades of the combined iris and shear unit being retracted away from the reform tub wall, so that coil forming takes place within the reform tub without interference. A support position with the blades extends into the reform tub and providing support for the coil; or a shear position for cutting the coil before it is extracted.

Coreless auger manufacture

A method for the handling of coreless auger, which is produced by an auger production machine from which the coreless auger emerges with a linear motion component and a rotational motion component, includes guiding the rotating auger for linear movement away from the production machine toward a temporary storage facility that has a cylindrical receptacle rotatable about its own axis and a coaxial rotatable feed guide having an axial inlet for formed auger and an outwardly directed outlet for directing formed auger toward an inner periphery of the cylindrical receptacle. The cylindrical receptacle is rotated and the feed guide is allowed to rotate about the axis of its inlet that is roughly coincident with the axis of auger entering the axial inlet of the feed guide. The cylindrical receptacle is rotated at a speed selected to counteract the rotation of the auger about its own axis.

ROLLING MILL POURING REEL

A pouring reel for forming a hot rolled long product into an annular coil comprises a central mast lying on a vertical axis. A cylindrical tub surrounds and cooperates with the central mast to form an annular tub chamber. A coil plate defines a bottom of the tub chamber. The central mast, cylindrical tub and coil plate are rotatable in unison about the vertical axis. An entry nozzle has a delivery end arranged to direct the product downwardly into the tub chamber for accumulation on the coil plate as a series of superimposed rings forming the coil. The coil plate is movable downwardly along the vertical axis and relative to the central mast and the cylindrical tub to accommodate the increasing height of the coil being formed in the tub chamber.

Coiling device with asymmetric cooling of the coiled strip

For a rolled metal strip, in particular a steel strip; a drive roller unit deflects the metal strip from a first transportation direction to a second transportation direction, and the strip is then fed to a coiler. The metal strip is coiled in the coiler to form a coil having a coil diameter. Plastic deformation of an end portion of the metal strip is caused such that the end portion in its uninfluenced state is curved at a curvature radius. The plastic deformation of the end portion (8) is at least partially caused by an asymmetric impingement with a cooling medium (21) on the sides of the end portion (8). The impingement of the end portion (8) with the cooling medium (21) is performed across a length of the end portion (8) that is longer than half the outermost coiling of the coil (6) but smaller than the outermost coiling of the coil (6).

SPHERICAL COIL WINDING MACHINE

An apparatus for winding coils onto a spherical body includes a frame, a feeder spool, a first hemispherical bobbin, a second hemispherical bobbin, a first spring-loaded pin, a second spring-loaded pin, and a motor arrangement. The feeder spool is rotationally mounted on the frame, has first and second wires wound thereon, and is configured to rotate about a first rotational axis. The first and second hemispherical bobbins are rotationally mounted on the frame and configured to rotate about a second rotational axis that is parallel to the first rotational axis. The bobbins are spaced apart from each other to define a wire-feeder gap through which the first and second wires may be fed. The motor arrangement is coupled to the first and second hemispherical bobbins and is configured to cause the first and second hemispherical bobbins to rotate in opposite directions about the second rotational axis.
