AI Technical Summary

Problems solved by technology

The dimensions of the machine and billet require large fabrication equipment to produce the tube, and the dimension requirements of the extrusion process result in high start-up and maintenance costs for the fabrication operation
Also, process constraints such as extrusion of one billet at a time lead to inefficiencies due to billet size

Abstract

Systems, devices, and methods for continuous extrusion of material billets are provided. A die assembly for press extrusion of a material includes a plurality of die plates forming a die body. The die body has an entrance and an exit having a diameter smaller than the entrance, with a tapered surface between the entrance and the exit. Each die plate has a center bore with a tapered interior surface, and the interior surfaces form the tapered surface that extends from the entrance to the exit. A base is coupled to the die body, and rotation of the base causes rotation of the die body. A billet pressed into the die body is heated by friction between the interior surface and an outer surface of the billet. The billet is heated to a deformable temperature and is extruded into a tube product as the billet is pressed from the entrance to the exit of the die body.

Description

Background technique [0001] Tubes such as metal tubes formed from copper, aluminum, metal alloys or other metallic materials are often produced by extrusion processes. In the extrusion process, a large block of metal, called a billet, is processed through a die structure having a circular or other configuration with openings smaller than the size of the billet used to form the tube. The blank may be preheated to an elevated temperature before the punching rod is forced through the center of the blank to form a channel through the blank. High pressure, typically on the order of 1,000 to 100,000 psi, is then applied to the body to force the preheated material over the perforated rod through the opening of the die. The pressure forces the material to deform and extrude, thereby exiting the back of the die as a tube with a diameter similar to that of the die opening. [0002] To produce large quantities of metal tube by extrusion, large billets and fabrication machinery are requ...
