Extruded Profile Produced with Rotating Shaping Dies

Abstract

A new way to design lightweight, strong, material efficient, extruded and pultruded profiles, profile segments (4) and surfaces produced in profile production with rotating dies creating superior resistance to compression, bending and buckling, higher energy absorption and right strength in the right place, by: varying the thickness along (_t)+across the direction of extrusion, making reinforcing patterns (2, 3), vary the profile thickness (t, _t), and in some cases vary angles (10, 11) and pattern (2, 3) which increases the profile segments / surface resistance against compression, bending and buckling relative to the amount of material used and resulting in that one can make optimized beams and surfaces that have superior properties in terms of strength / weight, stiffness / weight ratio, mechanical energy absorption / weight unit, deformation and natural frequency, thermal transfer capacity, the breaking of the laminar flow, increased / optimized surface for chemical and / or electrochemical reaction etc.

Description

TECHNICAL FIELD[0001]The present invention relates to a new principle to design profiles, profile segments, beams, elements for absorption of kinetic energy and surfaces / panels by varying the wall thickness along (_t)+across extrusion or pultrusions direction, making reinforcing patterns (2, 3), vary the profile thickness (T, _t), and in some cases vary, cross-sectional area (_A FIG. 11, 12, 15.2 angles (10, 11, FIG. 1) and pattern (2, 3, FIG. 1) which raises profile segments / panels resistance to bending, compression and buckling, relative to the amount of material used, enabling optimum performance for the purpose they are to serve, with minimum weight and minimum use of raw materials.[0002]The invention can be done in various forms in a number of different ways for different applications, with various requirements and is applicable to extrusion and pultrusion of plastically deformable materials and material combinations for example metal, metal composite, plastic, plastic composit...

AI Technical Summary

Benefits of technology

This approach results in profiles with improved weight-to-strength ratios, reduced material waste, and enhanced performance in crash management, energy absorption, and thermal transfer, enabling significant weight and material savings in vehicles and structural components.

Problems solved by technology

This is because a profile with the same cross-section or appearance all the way often do not qualify for meeting customers product and application requirements regarding design, function and performance particularly in automotive, aerospace, mass transportation, and structural applications.

The traditional methods first manufacturing profiles and then process until varied thickness and / or pattern requires very high costs for processing and machining equipment, which is due cost reasons altogether would exclude processing developed optimized profiles.

In addition, such machining result in broken material veining (generating fractural indication weaknesses).
