20.500.12556/DKUM-16540 ANALIZA IN IZBOLJŠANJE IZSEKOVANJA ODPRTIN NA VOTLIH PROFILIH IZ ALUMINIJEVIH ZLITIN ANALYSIS AND IMPROVEMENT OF PUNCHING HOLES ON HOLLOW PROFILES FROM ALUMINIUM ALLOYS Diplomsko delo pred vami analizira postopek izsekovanja odprtin na votlih profilih iz aluminijevih zlitin. Na podlagi te analize je v nadaljevanju dela podanih nekaj predlogov, kako omejiti izmet. V začetku diplomskega dela je predstavljeno izsekovanje in konkreten postopek, ki ga obravnava to delo. Po analizi izsekovanja so podani podatki o izmetu in o mehanskih lastnostih materiala profilov. Za konec je navedena povezava med mehanskimi lastnosti materiala in izmetom, ter predlaganih nekaj sprememb izsekovalnega stroja in orodja, ki bi pripomogle k zmanjšanju izmeta. Delo zaključuje sklep, ki pravi, da dobra konstrukcija stroja ni dovolj, pomembno je tudi redno vzdrževanje stroja. This dissertation in front of you analyses procedure of punching holes in hollow profiles from aluminium alloys. Based on this analysis this dissertation passes some proposal how to make ejection as small as possible. At the beginning of this work is presented a concrete cutting process. After analysis of punching are given information about the ejection and the mechanical properties of the material. Then is given, the relation between mechanical properties of the material and the ejection, and proposed some changes on punching machine and tool that would help to reduce scrap. The conclusion says that good design of the machine is not enough, very important is regular maintenance. izsekovanje rezilna orodja pestič matrica votel profil iz aluminijeve zlitine sila rezanja punching cutting tool punch matrix hollow profile from aluminum alloy cutting force true true false [D.
