Abstract
The specification discloses a nonferrous extrusion system and process providing improved transfer of extrusions from the runout table to the cooling table. The runout table includes interleaved runout rollers and transfer rollers that are vertically shiftable with respect to one another. The transfer rollers additionally are horizontally shiftable between the runout table and the cooling table. The runout table receives extrusions in a longitudinal direction. The vertical and horizontal shifting of the rollers is controlled to transfer the extrusions from the runout table to the cooling table.
Claims15
A nonferrous extrusion method comprising the steps of:
- receiving an extrusion in a longitudinal direction on a runout table, the runout table including runout rollers and transfer rollers in a first position so that at least one of the runout rollers and the transfer rollers supports the extrusion;
- vertically shifting the runout rollers and/or the transfer rollers with respect to one another to a second position so that the extrusion is supported only by the transfer rollers;
- laterally shifting the transfer rollers in a first direction to a third position in which the extrusion is supported above a cooling table;
- vertically shifting the transfer rollers to a fourth position so that the extrusion is deposited on the cooling table;
- and
- laterally shifting the transfer rollers in a second direction opposite to the first direction to return the transfer rollers to the first position.
A nonferrous extrusion handling system comprising:
- a runout table including runout rollers and transfer rollers vertically shiftable with respect to one another between a receive position and a transfer position, the transfer rollers being above the runout rollers in the transfer position, the transfer rollers being horizontally shiftable with respect to the runout rollers between a runout table position and a cooling table position, the transfer rollers being interleaved with the runout rollers in the runout table position, the transfer rollers being not interleaved with the runout rollers in the cooling table position, the runout rollers and the transfer rollers adapted to receive and support a nonferrous extrusion from a press;
- a cooling table;
- and
- a control adapted to control the relative vertical shifting of the runout rollers and the transfer rollers, and further adapted to control the horizontal shifting of the transfer rollers, to enable the transfer rollers to transport the extrusion from the runout table to the cooling table.
