Kodi ma sheet opindika azitsulo amagwiritsidwa ntchito bwanji?
Zigawo zopindika zachitsulo zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana opangira, monga zotchingira zamagetsi ndi zamagetsi, zotchingira, zitseko, mipando, mabulaketi, mizati, mafelemu, ndi zothandizira. Kupindika kwachitsulo ndi njira yopunthira zinthu kuti zikhale zomangika pogwiritsira ntchito mphamvu pa workpiece. Pali njira zosiyanasiyana zopindirira zitsulo, monga kupindika mabuleki osindikizira, kupindika, ndi kujambula mozama. Njira iliyonse ili ndi ubwino wake ndi zovuta zake, malingana ndi mtundu wa bend, zinthu, ndi kuchuluka kwa kupanga.
Zina mwazinthu zomwe zimakhudza mtundu ndi kulondola kwa magawo opindika achitsulo ndi mphamvu yopindika, m'lifupi mwake, m'lifupi mwake, gawo la bend, k factor, ndi springback. Zinthu izi zimadalira zinthu zakuthupi, makulidwe, utali wopindika, ndi mbali yopindika ya chidutswacho. Mainjiniya ndi opanga amayenera kuganizira izi popanga magawo opindika azitsulo kuti agwiritse ntchito kwambiri.
Momwe mungasankhire zida zopindika mwatsatanetsatane zitsulo?
Pali zinthu zingapo zomwe muyenera kuziganizira posankha zida zopindika mwatsatanetsatane zitsulo, monga mphamvu yazinthu, kukana dzimbiri, kulemera, kumaliza, ndi kusinthika. Nawa maupangiri okuthandizani kusankha zinthu zoyenera pulojekiti yanu:
● Sankhani zinthu zimene sizingafunike kumalizidwa, monga chitsulo chosapanga dzimbiri, aluminiyamu, kapena mkuwa kuti muwononge nthawi ndi ndalama.
●Sankhani chitsulo chosapanga dzimbiri ngati mbali zanu zikufunika kuwotcherera, chifukwa zimakhala ndi mphamvu zambiri, zolimba, komanso kukana kutentha ndi dzimbiri.
● Sankhani geji yoyenera, kapena makulidwe, azinthu, kutengera utali wopindika ndi ngodya. Zida zowonda ndizosavuta kupindika, koma sizingakhale zoyenera kugwiritsa ntchito zopsinjika kwambiri.
● Sankhani chinthu chokhala ndi processability wabwino, kapena luso lopangidwa popanda kusweka, kung'ambika, kapena kupindika. Zida zina, monga chitsulo cha carbon high, titaniyamu, kapena magnesium, zingafunike zida zapadera kapena mankhwala kuti apirire.
Potsatira malangizowa, mutha kuwonetsetsa kuti zomwe mwasankha zikugwirizana ndi momwe mungagwiritsire ntchito, zotheka, komanso zotsika mtengo za polojekiti yanu yopindika zitsulo.
Kodi sheet metal bend allowance ndi chiyani?
Pepala lachitsulo chopindika ndi muyeso wa kuchuluka kwa zinthu zomwe zimafunikira pakupinda gawo lachitsulo. Ndiko kusiyana pakati pa kuchuluka kwa miyeso iwiri yakunja ya bend ndi kutalika kwa lathyathyathya la pepala chitsulo1. Chilolezo chopindika chimadalira makulidwe azinthu, ngodya yopindika, utali wamkati wa bend, ndi k-factor yazinthu2. K-factor ndi yokhazikika yomwe imayimira malo osalowerera ndale mu bend, pomwe zinthu sizimatambasula kapena kuponderezana1. Chilolezo cha bend chikhoza kuwerengedwa pogwiritsa ntchito njira iyi:
BA=fracthetacdotpi180cdot(r+KcdotT)
kumene:
BA ndi gawo lopindika pamamita;
theta ndi ngodya yopindika mu madigiri;
pi ndi masamu osasinthasintha, pafupifupi ofanana ndi 3.14;
R ndi utali wopindika mkati mwa mita;
K ndiye k-chinthu chazinthu;
T ndiye makulidwe azinthu mu mita.
Ndalama yopindika imathandiza akatswiri ndi okonza mapulani kudziwa kutalika kwa chitsulocho asanapindike, kuti chomalizacho chigwirizane ndi zimene akufuna.
Ndizitsulo ziti zomwe zimatha kupindika bwino?
Zitsulo zina zomwe zimatha kupindika bwino ndi golide, siliva, chitsulo, mkuwa, ndi aluminiyamu1. Zitsulozi zimakhala ndi malleability kwambiri, zomwe zikutanthauza kuti zimapindika mosavuta popanda kusweka kapena kusweka. Malleability zimadalira kapangidwe ka atomiki zitsulo, komanso kutentha ndi kukakamizidwa ntchito kwa izo. Zitsulo zoyera ndizosavuta kusungunula kuposa zitsulo za alloy, zomwe zimakhala zosakanikirana ndi zitsulo zosiyanasiyana. Kupinda zitsulo kumafunanso kuganizira zinthu monga makulidwe a zinthu, ngodya yopindika, utali wopindika, ndi ma bend allowance. Zinthu izi zimakhudza mphamvu yopindika, kulondola, komanso mtundu wa bend.
