US 4,790,167 A · Extrusion run-out table

Abstract

An extrusion run-out table for aluminum extrusions and the like has an extrusion support table for supporting extruded profiles as they are extruded from an extrusion press along an extrusion path and a conveyor for moving the extruded shapes from the extrusion support table to a cooling area and to a further processing area. The extrusion support table includes a set of elongated heat-resistant bars mounted perpendicular to the extrusion path, with the bars extending laterally of the extrusion path into the cooling area a distance sufficient to position one or more of the extended shapes in laterally spaced relationship to the extrusion path. The extruded shapes are cooled through an air manifold above the extrusion path and through a series of air jet nozzles which project cooling air against the extruded shapes as they are extruded. The air jet nozzles are tailored to direct the quantity and direction of the cooling fluid against the shapes so as to minimize distortion of the shapes due to differential cooling. A special baffle arrangement is provided beneath one side of the support table and beneath an opposite side of the cooling area to direct the downwardly-moving cooling air laterally and then upwardly through the cooling area.

Dependent claims

In an extrusion run-out table for aluminum extrusions and the like, the run-out table comprising:

an extrusion support table for supporting extruded profiles as they are extruded from an extrusion press along an extrusion path;
conveyor means for moving the extruded shapes from the extrusion support table to a cooling area and to a further processing area;
side extrusion support table including a set of elongated heat-resistant support means mounted perpendicular to the extrusion path;
means to impart relative vertical motion between said conveyor means and said set of support means to alternatively support said extruded shapes on said conveyor means or on said set of support means;
the improvement which comprises:
said elongated heat-resistant support means having a length which extends laterally of said extrusion path into said cooling area and a distance sufficient to position at least one of said extruded shapes in laterally spaced relationship to the extrusion path to permit additional shapes to be extruded along the extrusion path while said at least one extruded shape is cooling in said cooling area and on said support means;
and
said conveyor means and said means to impart vertical motion index each successive extruded shape into said cooling area on said elongated support means subsequent to completion of extrusion thereof.
