Inqubo kanye nezidingo zobuchwepheshe zokukhiqiza ama-bolts aphezulu

1. Ukukhetha izinto ezibonakalayo
I-Carbon steel inamandla okwenza kahle kakhulu, ingahlangabezana nezinhlobonhlobo zezinhlanganisela zokusebenza kwamandla, futhi inezindleko eziphansi uma iqhathaniswa nezinye izinto zokubopha.
Izakhiwo zemishini ye-carbon steel ziyazwela kokuqukethwe kwekhabhoni, okuvamise ukuba ngaphansi kuka-1.0%. Sivame ukuhlukanisa insimbi ye-carbon ephansi (C% ≤ 0.25%), insimbi ye-carbon steel (0.25% 0.45%), kanye nensimbi ye-alloy (engeza izakhi ze-alloying ku-carbon steel evamile) ngokusekelwe kokuqukethwe kwekhabhoni ku-carbon steel material.
2. Spheroidization (softening) annealing
(1) Lapho kukhiqizwa izikulufu zekhanda ezi-spheroidized (zithambe) eziphikisayo ezine-annealed countersunk kanye namabhawodi angama-cylindrical ekhanda eliyi-hexagonal kusetshenziswa ubuchwepheshe besihloko esibandayo, ukwakheka kwasekuqaleni kwensimbi kuthinta ngqo ikhono lokubumba phakathi nokucubungula isihloko esibandayo. Phakathi nenqubo yesihloko esibandayo, ukuguqulwa kwepulasitiki ezindaweni zendawo kungafinyelela ku-60% -80%. Ngakho-ke, kuyadingeka ukuthi insimbi kufanele ibe ne-plasticity enhle.
(2) Okwensimbi ye-carbon steel kanye ne-medium carbon alloy steel enenani elikhuluama-fasteners aphezulu, ukufakwa kwe-spheroidization (ukuthambisa) kufanele kwenziwe ngaphambi kwesihloko esibandayo ukuze kutholwe i-pearlite efanayo ne-spheroidized, ukuze kuhlangatshezwane kangcono nezidingo zokukhiqiza ezingokoqobo.
3. Umdwebo wocingo
Yelula i-disc bese usebenzisa amandla ahambisanayo okudonsa kuyo ukuze ufinyelele i-diameter yocingo edingekayo (okungukuthi ububanzi) ukuze ikhiqize.
Amamaki obubanzi bentambo engaguquki amapuleti ayindilinga ayinqwaba ezigayweni zensimbi ahlanganisa i-M8, M10, M12, M16, njll. Angeke asetshenziselwe ngokuqondile ukukhiqizwa kwebhawodi. Isibonelo, ukukhiqiza ibhawudi eliluchungechunge eliphelele elingu-10mm kudinga ukudonsa ububanzi bediski bufike ku-8.78+0.04mm, kuyilapho ukukhiqiza ibhawudi elingu-16mm kudinga ububanzi bocingo obungu-14.38+0.02mm.
4.Ukuganga okubandayo
Ukwakhiwa kwe- i-hex boltikhanda lithatha ukucubungula okubandayo kwepulasitiki. Uma kuqhathaniswa nokusika ukucutshungulwa, i-fiber yensimbi (i-metal wire) iyaqhubeka nokuma komkhiqizo ngaphandle kokusika phakathi, ngaleyo ndlela ithuthukise amandla omkhiqizo futhi ithole izakhiwo ezinhle kakhulu zemishini. Inqubo yokwakhiwa kwesihloko esibandayo ihlanganisa ukusika nokwenza, ukuchofoza okukodwa kwesiteshi, ukuchofoza kabili isihloko esibandayo, kanye nesihloko esibandayo esizenzakalelayo seziteshi eziningi.
6. Ukucutshungulwa kwentambo
Imicu ye-bolt ngokuvamile icutshungulwa ngokusebenza okubandayo, lapho izikhala zentambo phakathi kobubanzi obuthile zihlikihlwa (zisongwe) ngepuleti lesikulufu (die), futhi imicu yakhiwa ukucindezela kwepuleti lesikulufu (i-rolling die). I-plastic streamline yengxenye ehlanganisiwe ingatholakala ngaphandle kokusikwa, okuholela ekukhuleni kwamandla, ukunemba okuphezulu, kanye nekhwalithi efanayo yomkhiqizo, osetshenziswa kakhulu.
Isici esivamile sokucubungula intambo (ukuhlikihla) ukuthi isivinini sokugoqa akudingeki sibe phezulu kakhulu. Uma iphezulu kakhulu, ukusebenza kahle kuphansi futhi ingaphezulu lamazinyo entambo lijwayele ukuhlukana noma ukuxhuma okungahlelekile. Ngokuphambene nalokho, uma inani lama-revolutions liphansi kakhulu, ububanzi bentambo buvame ukulahlekelwa yindilinga, futhi ingcindezi yokuqala ngesikhathi sokugoqa ikhuphuka ngokungavamile, okuholela ekuphileni kwesikhunta esifushane.
7. Ukwelashwa kokushisa
Ukwelashwa kokushisaama-fasteners aphezulukufanele ibhekane nokwelashwa kokucisha kanye nokushiswa ngokwezidingo zobuchwepheshe ukuze kuthuthukiswe izici zemishini ezibanzi zezinsimbi futhi ihlangabezane namanani ashiwo wamandla aqinile kanye nezilinganiso zesivuno somkhiqizo.
Ngenxa yomthamo omkhulu wokukhiqiza kanye nentengo ephansi yamabhawodi anamandla amakhulu, kanye nesakhiwo esithambile nesinemba kahle sengxenye efakwe imicu, kuyadingeka ukuthi okokusebenza kokwelapha ukushisa kufanele kube nokuhambisana okuqinile kokukhiqiza, izinga eliphezulu lokuzishintshashintsha, kanye nekhwalithi yokwelapha yokushisa ephezulu. Ukuze kukhiqizwe izixhumi eziqinile ezisezingeni eliphezulu, imishini yobuchwepheshe bokwelapha ukushisa esezingeni eliphezulu ibalulekile.
