Ingxenye.1 Idizayini Enhle
Isikhunta senzelwe ikakhulukazi izidingo zokusebenzisa, kanti isakhiwo saso kwesinye isikhathi asikwazi ukuba nengqondo ngokuphelele futhi ngokulinganayo ngokulinganayo. Lokhu kudinga ukuthi umqambi athathe izinyathelo eziphumelelayo lapho aklama isikhunta ngaphandle kokuthinta ukusebenza kwesikhunta, bese uzama ukunaka inqubo yokukhiqiza, ukuvumelanisa kwesakhiwo kanye nokulinganiswa kwesimo sejometri.
(1) Zama ukugwema amakhona abukhali nezingxenye ezinokwehluka okukhulu ngobukhulu
Kufanele kube noshintsho olubushelelezi ekuhlanganeni kwezingxenye eziwugqinsi nezimfushane zesikhunta. Lokhu kunganciphisa ngempumelelo umehluko wokushisa wesigaba sesiphambano, ukunciphisa ukucindezelwa okushisayo, futhi ngasikhathi sinye ukunciphisa ama-non-simonbaneity of the cross-engxenyeni, bese wehlisa ukucindezela kwezicubu. Umdwebo o-1 ukhombisa ukuthi isikhunta samukela i-fillet yokuguqula kanye nesigaxa soshintsho.
(2) Ngakhulisa kahle izimbobo zenqubo
Kweminye isikhunta esingakwazi ukuqinisekisa isigaba esifanayo nesinqamuleli se-symmetrical, kuyadingeka ukushintsha umgodi ongewona umgodi ngokusebenzisa umgodi noma ukukhulisa ezinye izimbobo zenqubo ngendlela efanele ngaphandle kokuthinta ukusebenza.
Umdwebo 2A ukhombisa ukufa ngethambo elincane, elizolimala njengoba kuboniswe umugqa wamachashazi ngemuva kokucisha. Uma izimbobo ezimbili zenqubo zingangezwa ekwakhiweni (njengoba kukhonjisiwe kuMdwebo 2b), umehluko wokushisa wesigaba senqubo yesiphambano ngesikhathi senqubo yokuqeda uncishisiwe, ukucindezelwa okushisayo kuyathuthukiswa kakhulu.
(3) Sebenzisa izakhiwo ezivaliwe nezilinganiselayo ngangokunokwenzeka
Lapho ukwakheka kwesikhunta kuvulekile noma i-asymmetrical, ukusatshalaliswa kwengcindezi ngemuva kokuquleka akunakulingani futhi kulula ukungcola. Ngakho-ke, ngokwejwayelekile umkhondo okhubazekile, isikhunta, ukuqiniswa kufanele kwenziwe ngaphambi kokucima, bese unqunywa ngemuva kokucima. Ukuhlanza isinqe okuboniswe kuMfanekiso 3 ekuqaleni kwakonakala ngo-R ngemuva kokucimana, futhi kuqiniswe (okuyingxenye eyenziwe ngesibalo 3), kungavimbela ngempumelelo ukuqeda ukonakala.
.
Okokufa okukhulu okunesimo esiyinkimbinkimbi nosayizi> 400mm kanye nama-punches anobukhulu obuncane nobude obude, kungcono ukwamukela isakhiwo esihlanganisiwe, ukwenza lula inqwaba kuya okuncane, nokushintsha indawo yangaphakathi , okungekho lula kuphela ukulungiswa nokupholisa ukucubungula.
Lapho uklama isakhiwo esihlanganisiwe, bekufanele ngokujwayelekile ukubola ngokuya ngemigomo elandelayo ngaphandle kokuthinta ukunemba okufanele:
- Lungisa ubukhulu ukuze isigaba sesiphambano sesikhunta esinezigcawu ezihlukile kakhulu ngokuyisisekelo umfaniswano ngemuva kokubola.
- Ukubola ezindaweni lapho ukucindezela kulula ukukhiqiza khona, kuhlakaze ukucindezeleka kwawo, futhi kuvikele ukuqhekeka.
- Sebenzisana nomgodi wenqubo ukwenza isakhiwo sivumelane.
- Ilungele ukucubungula okubandayo nokushisa futhi kulula ukuhlanganisa.
- Into ebaluleke kakhulu ukuqinisekisa ukusetshenziswa.
Njengoba kukhonjisiwe kuMfanekiso 4, kungukufa okukhulu. Uma kwamukelwa ukwakheka okubalulekile, hhayi ukwelashwa okushisa kuphela okuzoba nzima, kepha futhi nomgodi uzoncipha ngokungahambisani ngemuva kokucima, futhi kubangele ukungalingani nokuhlanekezela amabala onqenqemeni lokusika, okuzoba nzima ukulungisa ngokucubungula okulandelayo. Ngakho-ke, isakhiwo esihlanganisiwe singamukelwa. Ngokusho komugqa wamachashazi kuMdwebo 4, ihlukaniswe izingxenye ezine, nangemva kokwelashwa okushisa, ayabuthana futhi yakhiwa, bese inomhlabathi. Lokhu akukwenza lula ukwelashwa okushisa kuphela, kepha futhi kuxazulula inkinga yokuguquguquka.
Ingxenye.2 Ukukhetha okulungile
Ukushiswa kokwelashwa okushisa nokuqhekeka kuhlobene kakhulu nensimbi esetshenzisiwe nekhwalithi yayo, ngakho-ke kufanele isuselwe kwizidingo zokusebenza kwesikhunta. Ukukhetha okunengqondo kwensimbi kufanele kucatshangelwe ukunemba, ukwakheka nosayizi wokubumba, kanye nemvelo, ubungako kanye nezindlela zokucubungula zezinto ezisetshenzisiwe. Uma isikhunta esijwayelekile singenayo i-deformation kanye nezidingo zokunemba, insimbi yensimbi yekhabhoni ingasetshenziswa ngokuya ngokuncishiswa kwezindleko; Ngezingxenye ezikhubazekile kalula futhi eziqhekekile, insimbi yamathuluzi e-alloy ngamandla aphezulu kanye nejubane elibucayi futhi ijubane lokupholisa lingasetshenziswa; Isibonelo, isakhi se-elektroniki sifa ekuqaleni kwensimbi ye-T10A, deformation enkulu futhi kulula ukuqhekeka ngemuva kokupholisa kwamanzi nokupholisa uwoyela, futhi i-Alkali Bath junch ecintshisayo akulula ukwenza lukhuni. Manje sebenzisa insimbi engu-9MN2V noma insimbi ye-crwmn, ubulukhuni obucimayo kanye nokuguquguquka kwe-deformation kungahlangabezana nezidingo.
Kungabonakala ukuthi lapho ukwakheka kwesikhunta okwenziwe ngensimbi yekhabhoni akuhlangabezani nezidingo, kusabiza kakhulu ukusebenzisa insimbi ye-alloy efana ne-9mn2V yensimbi noma insimbi ye-crwmv. Yize izindleko ezibonakalayo ziphakeme kancane, inkinga yokuguquguquka nokuqhekeka kuxazululwa.
Ngenkathi ukhetha izinto zokwakha kahle, kuyadingeka futhi ukuqinisa ukuhlolwa nokuphathwa kwezinto ezingavuthiwe ukuvikela ukuqhekeka kokushisa kokushisa kokushisa ngenxa yezinkinga ezibonakalayo eziluhlaza.
