ANALYS AV TRÅDDRAGNINGSPROCESSEN

ANALYSIS OF THE WIRE DRAWING PROCESS (English)
Abstract [sv]

Rapporten handlar om analys av tråddragningsprocessen och är inriktad på de temperaturer som uppstår under dragning.

Tråddragning är en kallbearbetningsmetod men det uppstår höga temperaturer ända, dessa är inte alltid önskvärda.

Analysen utförs för att senare kunna göra förbättringar för att kunna öka draghastigheten utan att temperaturen ökar. Detta är önskvart då tidigare studier visar att energin som åtgar vid dragningen minskar vid högre hastighet.

Analysen utförs genom simuleringar av dragskivor under dragning, för att få värden att verifiera simuleringarna med gjordes ett industriforsök. Simuleringarna utförs med hjälp av den finita element metoden, FEM. Programmet som simuleringarna utförs i är Marc Mentat 2010.

Även andra resultat ifrån industriförsöket analyseras och diskuteras.

Abstract [en]

This paper is about the analysis of the wire drawing process and focuses on the temperatures that occur during drawing.

Wire drawing is a cold working method, but there are still high temperatures, however, these are not always desirable.

The analysis is performed in order to later be able to make improvements to increase the drawing speed without increasing the temperature. This is desirable since previous studies show that the energy that is used during the draw decreases at higher speeds. The analysis is performed through simulations of the die during the draw. In order to get values for the verification of the simulations an industrial trial was performed. The method for the simulations is the finite element method, FEM. The program used for simulations is Marc Mentat 2010.

Other results from the industrial trial are analyzed and discussed in the paper.
