Ukugqwala kwensimbi kukhona yonke indawo, ngaso sonke isikhathi

Ukuze uvimbele ukugqwala kwensimbi, indlela evame kakhulu ukusebenzisa izigqoko ukuvikela ubuso bemikhiqizo yensimbi.Ingaphezulu kufanele lihlanzwe ngaphambi kokuvikela ukunamathela.Amakhulu emikhiqizo nezimboni ezihlanganisa imikhumbi, amathangi okugcina, amabhuloho, izakhiwo zensimbi, iziteshi zikagesi, izimoto, izitimela, amathuluzi ezempi, izinto zokusebenza zasemkhathini, njll. kumele ziphathwe ngaphandle ngaphambi kokumbozwa.I-Metal abrasive iyindlela yokuhlanza ephumelela kakhulu.

Ama-abrasives ensimbi

Ngokuvamile, zikhonaphonsa isibhamu sensimbi (high carbon steel shotfuthilow carbon steel shot), insimbi yensimbi, insimbi, insimbi,insimbi engagqwali cut wire/conditioned shot, insimbi engagqwali,steel cut wire, ukuthwala igrit yensimbi, njll. Ama-abrasive ensimbi asebenza kahle akulula ukuphuka, uthuli oluncane, ukusetshenziswa okuphansi, ukuhlanza okuphezulu, nokusebenza kahle komkhiqizo wonke.Inganciphisa kakhulu izinga lokusetshenziswa komsebenzisi wokugcina, ngaleyo ndlela yehlise izindleko futhi inciphise ukukhishwa kwekhabhoni.

Ngakho-ke umbuzo uwukuthi, ungakhetha kanjani ama-abrasives ensimbi aphezulu?

Ukuqinisekisa ukuthi umphumela wokwelashwa ongaphezulu usezingeni ngokugcwele, izinkomba ezimbili eziyinhloko zama-abrasives ensimbi: ukuhlanza nokusebenza kahle nokusetshenziswa.

Ukungaqondi kahle okuningana ekukhetheni amashothi ensimbi:

Ingabe i-cast steel shot rounder ingcono?

Ingabe usayizi wezinhlayiyana ufana kakhulu, ungcono?

Ukubukeka okukhanyayo, kungcono?

Enqubweni yokwenza nokulungiselela amashothi ensimbi, insimbi encibilikisiwe iyapholiswa isuka oketshezini iye kokuqinile, futhi inciphe phakathi nenqubo yokupholisa.Lokhu kuncipha kwenziwa kusesimweni esikhululekile, futhi asikho isikhuphukeli esifana nokuthulula ukubunjwa ukuze kufakwe ingxenye yensimbi encibilikisiwe lapho umthamo ngemva kokuncipha uncishiswa, ngakho-ke kuvela izinhlayiya eziyielliptical ezinezindawo ezishonelwe.Lolu hlobo lwezinhlayiya luye lwancipha ngokwanele, futhi umumo awuwona oyindilinga kodwa isakhiwo siminyene.Kodwa-ke, uma isibhamu sensimbi esingakaqedwa ngokugcwele, isakhiwo asiminyene, kukhona ukukhubazeka kwangaphakathi okufana nokushwabana kwe-porosity kanye nemigodi yokuncipha.

Ukuphonsa amandla E=1/2mv2, uma isakhiwo siminyene, sinevolumu efanayo, ikhwalithi enkulu yokuminyana engu-M inamandla amakhulu, futhi akulula ukuphuka.Ngale ndlela, akulungile: insimbi eyindilinga idubule kangcono.

Ingabe usayizi wokusanhlamvu wensimbi udutshulwe umfaniswano owengeziwe, ungcono?

Emkhakheni wokuhlanza, ingaphezulu le-workpiece elizohlanzwa noma lifafazwe lizokwenza imigodi endaweni ehlanzekile.Kuphela lapho imigodi nemigodi kugqagqana ngokugcwele, yonke indawo ingahlanzwa kahle.

Uma usayizi wezinhlayiyana wokudubula kwensimbi uba umfaniswano kakhulu, kuthatha isikhathi eside ukufinyelela ukugqagqana ngokugcwele kwemigodi.Emashothi ensimbi anesilinganiso esithile sokuxuba usayizi wezinhlayiyana, amashothi ensimbi amakhulu asetshenziselwa ukuhlanza, kanye namashothi ensimbi amancane. izohlanza isikhala phakathi kwendawo ephathwa amashothi ensimbi anosayizi omkhulu

Ukubukeka okukhanyayo, kungcono?

Njengamanje kunezinhlobo ezimbili zehigh carbon steel shot: isibhamu esisodwa se-quenching steel kanye nesibhamu sensimbi sokucisha kabili.Kunzima ukuhlukanisa kusukela ekubunjweni, ukuqina, kanye nesakhiwo se-metallographic.Kodwa-ke, isibhamu sensimbi esicinywe kabili sinezinhlamvu ezinhle nempilo yokukhathala okuphezulu,Izinhlamvu zesibhamu esisodwa sokucisha ziqinile futhi impilo yokukhathala iphansi.Isibhamu esisodwa sokucima insimbi asicutshungulwe ngokushisisa nokucisha, ifilimu ye-Fe3O4 oxide yakheka ngo. ubuso buncane, bubukeka bukhanya kakhulu;kuyilapho insimbi idutshulwa ngemva kokwelashwa kwesibili kokucisha, ifilimu ye-Fe3O4 ebusweni iba mkhulu, ayibonisi ukukhanya, futhi ayibukeki icwebezela.Ngakho ubuso elikhanyayo akusho imikhiqizo engcono, kodwa uma kabili quenching steel shot noma cha kubaluleke kakhulu udaba.
