Kugwiritsa ntchito zinthu ndikofunikanso kwambirisiwokhazikika screw, ndicustom screwzinthu zomwe zingagwiritsidwe ntchito pazinthu zosiyanasiyana ndizosiyana, monga momwe zimagwirira ntchito pazinthu zosiyanasiyana, etc., malinga ndiCurrentmarket screwmanufactur makamaka monga carbon steel, zitsulo zosapanga dzimbiri, mkuwa zipangizo zitatu.
1.Chifukwa chiyani musankhe chitsulo cha carbon, chitsulo chosapanga dzimbiri, mkuwa?
Chitsulo cha Mpweya: Timasiyanitsa pakati pa chitsulo chochepa cha carbon, chitsulo chapakati cha mpweya ndi chitsulo cha carbon, ndi zitsulo za alloy ndi kuchuluka kwa carbon mu carbon steel.
(1)Chitsulo chochepa cha carbon C%≤0.25% chimadziwika kuti A3 zitsulo ku China. Mayiko akunja kwenikweni amatchedwa 1008, 1015, 1018, 1022, etc. Iwo makamaka ntchito mankhwala popanda kuuma zofunika monga 4.8 kalasi mabawuti, 4 kalasi mtedza ndizomangira zazing'ono. (Dziwani: Zinthu za 1022 zimagwiritsidwa ntchito kwambiri pobowola misomali.)
(2) Sing'anga mpweya zitsulo 0.25%
(3) High-carbon zitsulo C%>0.45%. Pakalipano, sichikugwiritsidwa ntchito pamsika
(4) Aloyi zitsulo: kuwonjezera zinthu alloying kuti wamba mpweya zitsulo kuonjezera katundu wapadera zitsulo: monga 35, 40 chromium molybdenum, SCM435, 10B38. Zomangira za Panvo makamaka zimagwiritsa ntchito chitsulo cha SCM435 chrome alloy, ndipo zigawo zikuluzikulu ndi C, Si, Mn, P, S, Cr, ndi Mo.
Mpweya wachitsulo wa carbonali ndi mphamvu zambiri komanso kuuma, kukana kuvala bwino, pulasitiki yolimba, komanso mtengo wotsika kwambiri wopanga. Zinthu izi zimapanga chitsulo cha carbon kukhala chinthu chabwino chopangira zigawo zokhazikika.
Chitsulo chosapanga dzimbiri: kalasi yantchito: 45, 50, 60, 70, 80
Zigawo zazikuluzikulu ndi austenite (18% Cr, 8% Ni), yomwe imakhala ndi kutentha kwabwino, kukana kwa dzimbiri komanso kutsekemera kwabwino. A1, A2, A4 martensitic ndi 13% Cr ali ndi vuto losachita dzimbiri, mphamvu zambiri komanso kukana kuvala bwino. C1, C2, C4 ferritic chitsulo chosapanga dzimbiri. 18% Cr kukhumudwitsa ndikwabwino, ndipo kukana kwa dzimbiri ndikolimba kuposa kwa martensite. Pakadali pano, zinthu zomwe zimatumizidwa pamsika ndizogulitsa makamaka ku Japan. Malinga ndi mulingowo, amagawidwa makamaka SUS302, SUS304, ndi SUS316.
Zowononga zitsulo zosapanga dzimbiriimakhala ndi dzimbiri labwino kwambiri, imatha kusungidwa pamalo abwino kwa nthawi yayitali m'malo ovuta, komanso sikophweka kuchita dzimbiri. Kuphatikiza apo, chitsulo chosapanga dzimbiri chimakhala ndi mphamvu zambiri, zokometsera zabwino, komanso kukonza kosavuta.
Mkuwa: Zomwe zimagwiritsidwa ntchito kwambiri ndi mkuwa ... Zinc-copper alloy. H62, H65 ndi H68 mkuwa amagwiritsidwa ntchito makamaka ngati magawo amsika.
Copper screwali wabwino madutsidwe magetsi, matenthedwe madutsidwe, kukana dzimbiri ndi processing katundu, ndipo akhoza welded ndi brazed. Zinthu izi zimapangitsa mkuwa kukhala wothandiza pakufalitsa mphamvu, ma motors
2 Kodi pali kusiyana kotani pakati pa chitsulo chosapanga dzimbiri ndi chitsulo cha carbon?
Chitsulo chosapanga dzimbiri ndi zitsulo za carbon ndi zipangizo zachitsulo, ndipo anthu ambiri sadziwa kusiyana pakati pa zitsulo zosapanga dzimbiri ndi carbon zitsulo.
Kodi pali kusiyana kotani pakati pa chitsulo chosapanga dzimbiri ndi chitsulo cha carbon? Malingana ndi cholinga ndi zotsatira zake, nthawi zambiri pamakhala kusiyana kotere:
(1) Chitsulo chosapanga dzimbiri chimakhala ndi matenthedwe otsika komanso ocheperako chifukwa cha kusayenda bwino kwamafuta ndi elongation, kotero mphamvu yopindika yofunikira ndi yayikulu;
(2) Poyerekeza ndi chitsulo cha carbon, mbale ya chitsulo chosapanga dzimbiri imakhala ndi chizolowezi champhamvu chobwereranso popinda;
(3) Poyerekeza ndi carbon zitsulo, chifukwa otsika elongation wa zosapanga dzimbiri mbale, ndi kupinda ngodya R ya workpiece ayenera kukhala wamkulu kuposa mpweya zitsulo pamene kupinda, apo ayi pali kuthekera ming'alu;
(4) Chifukwa cha kuuma mkulu wa zitsulo zosapanga dzimbiri mbale ndi zotsatira yaikulu ya ntchito ozizira kuumitsa, posankha psinjika anapinda zida, chida zitsulo ndi kutentha mankhwala kuuma kuposa 60HRC ayenera kusankhidwa, ndipo pamwamba roughness ayenera chofunika.
Ku Yuhuang,wopanga china wonongaife tikudziwa izowononga wapamwambazopangira ndiye maziko opangira zinthu zabwino kwambiri. Choncho, aliyensescrewamapangidwa ndi zitsulo zamphamvu kwambiri, zitsulo zosapanga dzimbiri ndi zipangizo zina zapamwamba zomwe zakhala zikuyang'aniridwa mosamala kuti zitsimikizire kuti sizingokhala ndi mphamvu zonyamula katundu komanso kukana dzimbiri, komanso zimakhala ndi ntchito yokhazikika komanso yodalirika m'madera ovuta kwambiri. Kusankha zomangira za Yuhuang, mukusankha chitsimikizo chamtundu wabwino.
