Yiziphi izinto ezivame ukufakwa ekuhlolweni kwekhwalithi yezingxenye zokucwiliswa kwesithando somlilo esishisayo?

Ukuhlolwa kwekhwalithi ye- isithando sokushisa sangaphakathi Izingxenye ezicinyiwe kufanele zifake phakathi izinto eziyisikhombisa zokubukeka, ubulukhuni, indawo eqinisiwe, ukujula kongqimba oluqinile, isakhiwo se-metallographic, ukusonteka nokuqhekeka.

(1) Ukubukeka Ubuso bezingxenye ezicinyiwe zesithando sokufudumeza sokungeniswa ngeke bube nezinkinga ezinjengokuhayiza, imifantu, njll. Indawo ejwayelekile yokucinywa imhlophe qwa ngombala omnyama (isikali se-oxidized). Okumhlophe okumpunga ngokuvamile kukhombisa ukuthi izinga lokushisa elicimayo liphezulu kakhulu, futhi ingaphezulu lilonke limnyama noma liluhlaza okwesibhakabhaka, futhi ngokujwayelekile likhombisa ukuthi izinga lokushisa elicimayo alanele. Ukuqhekeka kwendawo nokuqhekeka okusobala, ama-avalchi, namakhona kungatholakala ngesikhathi sokuhlolwa okubukwayo. Ezingxenyeni ezincane ze-batch nezenziwe ngobuningi, izinga lokuhlola ukubukeka lingu-100%.

(2) Ubulukhuni bungahlolwa endaweni lapho kuhlolwa khona i-Rockwell hardness. Izinga lokuhlolwa kwamabala linqunywa ngokuya ngokubaluleka kwezingxenye nokuqina kwenqubo, imvamisa i-3% ~ 10%, ingezelelwa ngokuhlolwa kommese noma ukuhlolwa kwemimese engu-100%. Ngesikhathi sokuhlolwa kwemimese, umhloli kufanele alungiselele amabhlogo ajwayelekile wobulukhuni obuhlukile (imvamisa emise imikhono) ukuqhathanisa, ukuze kuthuthukiswe ukunemba kokuhlolwa kwemimese. Ekukhiqizeni okuzenzakalelayo, indlela yokuhlola ubulukhuni esezingeni eliphakeme yamukele umhloli wamanje we-eddy nokunye ukuhlolwa.

(3) Indawo eqinisiwe ivame ukulinganiswa nerula noma i-caliper yokukhiqiza okuncane kwe-batch, futhi indawo nayo ingafakwa nge-asidi enamandla ukwenza indawo emhlophe eqinile ivele ukuze ihlolwe. Indlela ye-etching ivame ukusetshenziselwa ukulungiswa nokuhlolwa. Ekukhiqizweni ngobuningi, uma isifudumezi sokungeniswa se- isithando sokushisa sangaphakathi noma indlela elawula indawo yokuqina inokwethenjelwa, imvamisa kuyadingeka kuphela ukusampula, futhi izinga lesampula lingu-1% kuye ku-3%.

(4) Ukujula kwesendlalelo esiqinisiwe Ukujula kongqimba oluqinile njengamanje kusetshenziselwa ukusika ingxenye ebekiwe yokuhlola yengxenye ecinyiwe ukukala ukujula kongqimba oluqinile kule ngxenye. Esikhathini esedlule, indlela ye-metallographic ibisetshenziselwa ukukala ukujula kongqimba oluqinile eChina. Manje, ngokuya nge-GB / T 5617-2005, ukujula kwesendlalelo esiqinisiwe kunqunywa ngokulinganisa ubulukhuni besigaba sogqinsi oluqinile. Ukuhlolwa kokujula kongqimba oluqinile ngokuvamile kudinga ukulimala kwezingxenye. Ngakho-ke, ngaphandle kwezingxenye ezikhethekile nemithethonqubo ekhethekile, kwenziwa ukuhlolwa okungahleliwe kuphela. Ukukhiqizwa okukhulu kwezingxenye ezincane kungabhekelwa ucezu olungu-1 kushift ngayinye noma ucezu olu-1 kuzo zonke izingcezu eziyi-100, 500 ezikhiqiziwe, njll, futhi izingxenye ezinkulu zingabhekelwa ucezu olungu-1 ngenyanga, njll. Uma usebenzisa okuthuthukile imishini yokuhlola engonakalisi, izinga lesampula lingakhuphuka, ngisho nokuhlolwa okungu-100%.

(5) Isakhiwo se-Metallographic Izinto zokwenziwa kwe- isithando sokushisa sangaphakathi izingxenye ezicishiwe ikakhulukazi zensimbi yensimbi emaphakathi nensimbi yensimbi, futhi ukwakheka kwezingxenye ezincane okucishiwe ngokuvamile kufana nobulukhuni. Kwezinye izingxenye ezibalulekile, izidingo ze-microstructure zishiwo kwimidwebo yokuklama, ikakhulukazi ukuvimbela ama-martensite ama-coarse akhiqizwa ukushisa ngokweqile, futhi ngasikhathi sinye ukuvimbela i-ferrite engachithwanga ekhiqizwa ngokushisa.

(6) I-Deformation Deformation isetshenziselwa kakhulu ukuhlola izingxenye ze-shaft. Ngokuvamile, ifreyimu ephakathi nendawo nenkomba yokudayela isetshenziselwa ukukala umehluko we-swing wezingxenye ngemuva kokucima. Umehluko we-pendulum uyehluka ngokuya ngobude nobubanzi besilinganiso sezingxenye. Izingxenye ezicinywe isithando somlilo sokungeniswa zingaqondiswa, futhi inani lokuphambuka lingaba likhulu kancane. Ngokuvamile, umehluko we-pendulum ovunyelwe uhlobene nenani lokugaya ngemuva kokucima. Inani elincani lokugaya lincane, umehluko omncane ovumelekile we-pendulum. Ububanzi bezingxenye ze-shaft ejwayelekile imvamisa ingu-0.4 ~ 1mm. Vumela umehluko we-swing wezingxenye ngemuva kokuqondiswa ngu-0.15 ~ 0.3mmo

(7) Izingxenye ezinemifantu ebaluleke kakhulu zidinga ukuhlolwa ngokuhlolwa kwezinhlayiyana kazibuthe ngemuva kokucima, futhi amafemu anemishini engcono asebenzise ama-phosphors ukukhombisa imifantu. Izingxenye ezenziwe ukuhlolwa kwezinhlayiyana kazibuthe kufanele zifakwe amandla kazibuthe ngaphambi kokufaka inqubo elandelayo.
