Momwe Mungapangire Zodula za PDC
Momwe mungapangire zodula za PDC
PDC Cutter idapangidwa koyamba ndi General Electric (GE) mu 1971. idayambitsidwa pazamalonda mu 1976 itatha kutsimikiziridwa kuti ndiyothandiza kwambiri kuposa kuphwanya zochita za mabatani a carbide. Ma bits a PDC tsopano atenga zoposa 90% ya zojambula zonse padziko lapansi. Koma kodi mukudziwa momwe ocheka a PDC amapangidwira? Ndikufuna kugawana nanu zambiri pano.
Zipangizo
kusankha umafunika diamondi, kuphwanya ndi kuwumba kachiwiri, kupanga tinthu kukula yunifolomu, kuyeretsa diamondi zakuthupi. Kwa tungsten carbide gawo lapansi timagwiritsa ntchito ufa wapamwamba kwambiri wa namwali komanso kalasi yoyenera ya carbide yokhala ndi kukana kwakukulu.
Kusintha kwa HTHP
1. akatswiri oyendetsa ndi zipangizo zotsogola kupanga odula PDC
2. fufuzani kutentha ndi kupanikizika mu nthawi yeniyeni ndikusintha nthawi. Kutentha ndi 1300 - 1500℃. Kupanikizika ndi 6 - 7 GPA.
3. Kupanga chidutswa chimodzi cha PDC Cutters kudzafunika pafupi mphindi 30 zonse.
Kuwunika koyamba kwa zidutswa
Asanayambe kupanga misa, yang'anani gawo loyamba kuti muwone ngati likukwaniritsa zofunikira za kasitomala pakukula ndi magwiridwe antchito.
Kupera
1. dimension akupera: akupera awiri akunja ndi kutalika. ntchito cylindrical chopukusira kuchita kunja akupera kwa mankhwala billet. Chifukwa chakuti zinthuzo zikhoza kusinthasintha panthawi ya kuthamanga kwapamwamba kwambiri komanso kutentha kwapamwamba, zomwe zapezedwa sizingakhale ndi mawonekedwe abwino ndikukwaniritsa zofunikira za maonekedwe a mankhwala, ndipo silinda yabwino iyenera kupezeka kudzera mukupera kwakunja.
2. Chamfer akupera: chamfer ayenera kukhala pafupifupi 0.1-0.5mm ndi ngodya 45; ndichamfer ikhoza kudulidwa mpaka madigiri osiyanasiyana malinga ndi zomwe kasitomala akufuna.
Kuyang'anira zinthu zomalizidwa
Kuonetsetsa kuti odula onse a PDC ali oyenerera komanso osasinthasintha, tiyenera kuyang'ana odula omaliza a PDC. Kuyang'anira zinthu monga mawonekedwe, kukula kwake, ndi magwiridwe antchito akuyenera kuchitidwa, kenako ndikuyika ndikunyamula zinthuzo zitawunikiridwa kuti zikhale zoyenerera. Ichi ndi sitepe yofunika kutsimikizira mankhwala khalidwe; kuyeza kwa makulidwe a diamondi ya polycrystalline kuyenera kutsindika pakuwunika kwazinthu.
Kulongedza
Maonekedwe ndi miyeso ya mankhwala omwe akutuluka ayenera kukumana ndi mafakitale, kuphatikizapo, maonekedwe ndi miyeso ya mankhwala sayenera kusintha panthawi yoyenda mtunda wautali. Choyamba mu bokosi la pulasitiki, kenako mu katoni.50 zidutswa mu bokosi lililonse pulasitiki.
Pa ZZbetter, titha kupereka osiyanasiyana odula enieni.
