US 11,897,013 B2 · Metal part extrusion control

Abstract

A technique for optimizing metal extrusion process parameters includes receiving values representing properties of an extrusion press machine, and calculating an estimated surface exit temperature of a metal work product resulting from an extrusion of a metal billet using the extrusion press machine based on the machine property values, an initial temperature of the metal billet prior to the extrusion, an extrusion force applied to the metal billet during the extrusion, and an extrusion speed of the metal work product. The estimated surface exit temperature of the metal work product is compared with a target hot shortness exit temperature of the metal work product. The initial temperature of the metal billet, the extrusion speed, and the extrusion force are changed based on the comparison until the estimated surface exit temperature equals the target hot shortness exit temperature.

Dependent claims

A system comprising:

a storage;
and
a processor operatively coupled to the storage, the processor configured to execute instructions stored in the storage that when executed cause the processor to carry out a process comprising:
receiving a plurality of machine property values representing properties of an extrusion press machine;
calculating an extrusion ratio of an extruded profile of a metal work product based on the properties of the extrusion press machine;
comparing a diameter of a circumscribing circle diameter (CCD) of the extruded profile to a billet diameter (Do) of the extrusion press machine;
determining whether the CCD is less than a fraction of the Do;
and
commanding the extrusion press machine to extrude the metal work product if the CCD is determined to be less than the fraction of the Do, otherwise selecting a different extrusion press machine to extrude the metal work product.
