\u00dckskord murdsin alumiiniumprofiili, kui proovisin ilma toestuseta 180\u00b0 painutada. \u00d5ppisin raskelt - tihedad k\u00f5verad vajavad planeerimist, t\u00f6\u00f6riistu ja tehnikat.<\/p>\n

Alumiiniumprofiilide 180\u00b0 painutamiseks kasutage p\u00f6\u00f6rlevat t\u00f5mbet\u00f5mbet\u00f5mbet, rakendades m\u00f5\u00f5dukat kuumust ja s\u00e4ilitades \u00f5ige painutusraadiuse.<\/strong><\/p>\n

Milline on parim meetod alumiiniumprofiilide 180\u00b0 painutamiseks?<\/h2>\n

Erinevad t\u00f6\u00f6riistad sobivad erinevatele vajadustele. Siin on, kuidas ma valin \u00f5ige painutusmeetodi:<\/p>\n\n\n\n\n\n\n\n\n

P\u00f6\u00f6rlev t\u00f5mbamine on parim teravate 180\u00b0 kurvide jaoks. See toetab profiili k\u00f5veruse sees oleva t\u00fcvega, mis hoiab seinad kokkuvarisemise v\u00f5i pragunemise eest.<\/p>\n

See pakub t\u00e4pset kontrolli, sujuvat viimistlust ja toetab tihedaid radiaale t\u00fcvede abil.<\/p><\/div>

<\/svg> Kolme rulli painutamine on ideaalne v\u00e4ga v\u00e4ikese raadiusega 180\u00b0 painutuste jaoks.<\/b>Vale<\/span><\/p>

Kolme rulli painutamine sobib suurema raadiusega painutustele, mitte teravatele 180\u00b0 k\u00f5veratele.<\/p><\/div><\/p>\n

\n

Kas ekstrusiooni saab eelnevalt painutada v\u00f5i on vaja sekundaarseid toiminguid?<\/h2>\n

Minult on k\u00fcsitud, kas me saame 180\u00b0 kuju otse ekstrudeerida. Vastus on alati eitav.<\/p>\n

Alumiiniumprofiil peab olema sirge. Painutamine toimub alati teisese toimingu k\u00e4igus.<\/strong><\/p>\n

K\u00f5vera ekstrusioon tekitaks eba\u00fchtlase seinapaksuse, n\u00f5rgad kohad ja t\u00f6\u00f6riistadega seotud probleemid. Selle asemel pressime profiili sirgeks ja painutame selle seej\u00e4rel masinaga.<\/p>\n

See annab puhta kuju, t\u00e4psed m\u00f5\u00f5tmed ja kontrolli seina terviklikkuse \u00fcle.<\/p>\n

V\u00e4ljapressimistooted peavad olema sirged; painutamine toimub p\u00e4rast seda, kasutades selleks etten\u00e4htud meetodeid.<\/p><\/div>\n

\n

Kuidas v\u00e4ltida pragunemist kitsaste kurvide ajal?<\/h2>\n

Tihedad kurvid r\u00f5hutavad alumiiniumi v\u00e4lisraadiust. Praod tekivad, kui:<\/p>\n

    \n
  • Painutusraadius on liiga v\u00e4ike<\/li>\n
  • Sulam on liiga habras<\/li>\n
  • Puudub sisemine toetus<\/li>\n<\/ul>\n

    Pragunemise v\u00e4ltimiseks kasutage \u00f5iget raadiust, lisage torne, kuumutage profiili \u00f5rnalt ja painutage aeglaselt.<\/strong><\/p>\n

    Minu kontrollnimekiri pragude v\u00e4ltimiseks:<\/h3>\n

    1. Minimaalne raadius<\/strong>: J\u00e4rgige sulamip\u00f5hiseid eeskirju. 6061-T6 puhul ei tohi minna alla 2,5x seinapaksuse.<\/li>\n
    2. Toetus koos t\u00fcvega<\/strong>: Eriti \u00f5\u00f5nsate v\u00f5i \u00f5hukese seinaga pressprofiilide puhul.<\/li>\n
    3. Soojuse-eelne tsoon<\/strong>: t\u00f5sta temperatuuri ~200-300?\u00b0C-ni, et parandada plastilisust.<\/li>\n
    4. Aeglane painutuskiirus<\/strong>: Laske alumiiniumil j\u00e4rk-j\u00e4rgult deformeeruda.<\/li>\n
