Ngokuvamile, ikhanda lomshudo lakhiwa ukucubungula kwepulasitiki okukhanda okubandayo, uma kuqhathaniswa nokucutshungulwa, i-fiber yensimbi (i-metal wire) eduze nokuma komkhiqizo iyaqhubeka, ngaphandle kokusika phakathi, okuthuthukisa amandla omkhiqizo, ikakhulukazi izinto ezinhle kakhulu zemishini.Inqubo yokwakhiwa kwesihloko esibandayo ihlanganisa ukusika nokwenza, chofoza okukodwa, kabili - chofoza isihloko esibandayo kanye nesihloko esibandayo esizenzakalelayo se-multi - isikhundla. .I-Simplex bit noma i-multi-station othomathikhi ekhanda umshini wokubanda othomathikhi usebenzisa izici zokucubungula zento engenalutho yasekuqaleni yenziwe ngosayizi wezinto ezibonakalayo 5 kuya ku-6 amamitha ubude noma isisindo singu-1900-2000 kg wosayizi wentambo yensimbi yensimbi, ukucutshungulwa. ubuchwepheshe yizimpawu zokwakheka kwesihloko esibandayo akulona ishidi elisikiwe elingenalutho kusenesikhathi, kodwa LISEBENZISA umshini wokubanda ozenzakalelayo ngokwawo nge-bar kanye nentambo yensimbi yocingo olusikiwe futhi iphazamise okungenalutho (uma kunesidingo).Ngaphambi kwe-extrusion cavity, okungenalutho kufanele ukubunjwa kabusha.Okungenalutho kungatholakala ngokubunjwa.Okungenalutho akudingi ukulolongwa ngaphambi kokucasula, ukunciphisa ububanzi nokucindezela.Ngemva kokuba okungenalutho kunqanyuliwe, kuthunyelwa esiteshini somsebenzi esicasulayo.Lesi siteshi singathuthukisa ikhwalithi yokungenalutho, ukunciphisa amandla okwakhiwa kwesiteshi esilandelayo ngo-15-17%, futhi andise impilo yesikhunta.Ukunemba okutholakala ngokubunjwa kwesihloko esibandayo nakho kuhlobene nokukhethwa kwendlela yokwakha kanye nenqubo esetshenziswayo.Ngaphezu kwalokho, kubuye kuncike ekutheni izici zesakhiwo semishini esetshenziswayo, izici zenqubo kanye nesimo sazo, ukunemba kwamathuluzi, izinga lokuphila kanye nokuguga. Ngensimbi ephezulu ye-alloy esetshenziswa esihlokweni esibandayo kanye ne-extrusion, ukuhwaqeka kwendawo yokusebenza ye-hard alloy die akufanele kube i-Ra=0.2um, lapho ubulukhuni obusebenzayo befa elinjalo bufinyelela ku-Ra=0.025-0.050um, bunokuphila okuphezulu.
Intambo yebhawodi ivame ukucutshungulwa ngenqubo ebandayo, ukuze isikulufu esingenalutho phakathi kobubanzi obuthile sigoqeke ngepuleti lentambo (die), futhi intambo yakhiwe ukucindezela kwepuleti lentambo (die).Isetshenziswa kakhulu ngoba isetshenziswa kakhulu ngoba i-plastic streamline ye-screw thread ayinqunywa, amandla ayanda, ukunemba kuphezulu futhi izinga lifana. ngoba inqunyelwe ukunemba kwentambo, kungakhathaliseki ukuthi ukumbozwa kwezinto ezibonakalayo nezinye izici.Ukugoqa (ukugoqa) intambo yokucindezela kuyindlela yokwenza amazinyo entambo ngokuguqulwa kwepulasitiki. rolling wire plate) die, olunye uhlangothi ukuze extrude igobolondo cylindrical, olunye uhlangothi ukwenza igobolondo ukuzungezisa, the final rolling die on the shape oyindilinga idluliselwe igobolondo, ukuze intambo ukwakha.Rolling (hlikihla) ingcindezi intambo processing iphuzu evamile ukuthi inani rolling revolution akuyona kakhulu, uma kakhulu, ukusebenza kahle liphansi, ebusweni amazinyo intambo kulula ukukhiqiza ukuhlukana noma isiphithiphithi buckle mkhuba.Ngokuphambene nalokho, uma inani revolutions lincane kakhulu, intambo I-diameter kulula ukulahlekelwa indilinga, ingcindezi eginqikayo ikhuphuka ngendlela engavamile ekuqaleni, okuholela ekuphileni okufushane kokufa. Amaphutha avamile entambo egoqekayo: ukuqhekeka okungaphezulu noma ukuklwebheka entanjeni;Ibhande elingahlelekile;Intambo iphelelwe yindilinga.Uma lezi amaphutha avela kuNombolo enkulu, azotholakala esigabeni sokucubungula.Uma inombolo encane yalezi ziphambeko zenzeka, inqubo yokukhiqiza ngeke ibone ukuthi lezi ziphambeko zizogeleza kumsebenzisi, okubangela inkinga.Ngakho-ke, izinkinga ezibalulekile zezimo zokucubungula kufanele kufingqwe ukuze kulawulwe lezi zici ezibalulekile kunqubo yokukhiqiza.
Izibophelelo zamandla aphezulu zizoqiniswa futhi zithanjiswe ngokuvumelana nezidingo zobuchwepheshe. Inhloso yokwelashwa kokushisa nokushisa iwukuthuthukisa izici zemishini ezibanzi zezinsimbi ukuze zihlangabezane nenani elishiwo lamandla aqinile kanye nesilinganiso samandla okugoba. Ubuchwepheshe bokwelapha ukushisa bunomthelela obalulekile ikhwalithi yangaphakathi ye-fasteners yamandla aphezulu, ikakhulukazi ikhwalithi yayo yangaphakathi. Ngakho-ke, ukuze kukhiqizwe ama-fasteners aphezulu, kuyadingeka ukuthi ube nemishini yobuchwepheshe yokwelapha ukushisa okuthuthukisiwe.Ngenxa yomthamo omkhulu wokukhiqiza kanye nentengo ephansi yama-bolts anamandla amakhulu, kanye nesakhiwo esilinganiselwe nesinembile intambo yesikulufu, imishini yokwelapha ukushisa iyadingeka ukuze ibe nomthamo omkhulu wokukhiqiza, izinga eliphezulu lokuzenzakalela kanye nekhwalithi enhle yokwelashwa kokushisa.Kusukela ngeminyaka yawo-1990, umugqa wokukhiqiza wokushisa oqhubekayo onomoya ovikelayo ube sendaweni evelele. Uhlobo lwe-shock-bottom kanye nesithando somlilo se-net-belt zifaneleka ngokukhethekile ekwelapheni ukushisa nokushisa kwama-fasteners amancane naphakathi.Umugqa wokushisa ngaphandle kwesithando somlilo ovaliwe ukusebenza kuhle, kodwa futhi unomkhathi othuthukisiwe, izinga lokushisa, kanye nemingcele yenqubo. isilawuli sekhompuyutha, i-alamu yokuhluleka kwemishini kanye nemisebenzi yokubonisa.Izibophelelo ezinamandla amakhulu zisebenza ngokuzenzakalelayo kusukela ekuphakeleni - ukuhlanza - ukufudumeza - ukucisha - ukuhlanza - ukushisa - ukufaka umbala kumugqa ongaxhunyiwe ku-inthanethi, ukuqinisekisa ngempumelelo ikhwalithi yokwelashwa kokushisa.The decarburization of screw thread kuzobangela ukuthi isibopheli sigebeke kuqala uma sehluleka ukuhlangabezana nokumelana nezidingo zokusebenza kwemishini, okuzokwenza isibophelelo sesikulufu silahlekelwe ukusebenza kahle futhi sifinyeze impilo yesevisi.Ngenxa ye-decarbonization yezinto ezingavuthiwe, uma ukuhushula kungafanele, kuzokwenza Ungqimba lwe-raw material decarbonization luyajula.Ngesikhathi sokucisha nokwelashwa kokushisa, amanye amagesi akhipha i-oxidizing ngokuvamile alethwa ngaphandle kwesithando somlilo.Ukugqwala kwentambo yensimbi yensimbi noma okusele ocingweni ngemva komdwebo obandayo kuzobola ngemva kokushisisa esithandweni. , ekhiqiza igesi ene-oxidizing.Ukugqwala kocingo lwensimbi, isibonelo, kwenziwa nge-iron carbonate ne-hydroxide, ngemva kokuba ukushisa kuzohlukaniswa kube yi-CO ₂ kanye ne-H ₂ O, ngaleyo ndlela kubhebhethekise ukubola. Imiphumela ibonisa ukuthi idigri ye-decarburization yensimbi yensimbi ye-carbon alloy ibucayi kakhulu kune-carbon steel, futhi izinga lokushisa elisheshayo lokususa incarburization liphakathi kuka-700 no-800 degrees Celsius. Ngoba okunamathiselwe phezu kocingo lwensimbi kuyabola futhi kuhlanganiswe kube yi-carbon dioxide namanzi ngesivinini esisheshayo ngaphansi kokuthile izimo, uma ibhande eliqhubekayo lebhande lokulawula igesi yesithando somlilo lingafanelekile, lizophinde libangele iphutha le-screw decarbonization. phezulu kwentambo, okuholela ekunciphiseni izakhiwo zemishini (ikakhulukazi amandla nokumelana nokuhuzuka) ebusweni bezinsimbi ezidinga ukuqina.Ngaphezu kwalokho, i-surface decarburization yocingo lwensimbi, i-surface kanye nenhlangano yangaphakathi ihlukile futhi ine-coefficient yokwandisa ehlukile, Ukucisha kungase kukhiqize imifantu ebusweni.Ngakho-ke, ukuvikela intambo phezulu decarburization in ukushisa quenching, kodwa futhi izinto zokusetshenziswa iye ngokulinganisela camera carbon decarburization of fasteners, vula inzuzo enezikhala ibhande isithando somlilo umkhathi zokuzivikela in the alinganayo eziyisisekelo. Kokuqukethwe kwekhabhoni yasekuqaleni kanye nezingxenye zokumboza ikhabhoni, izifakelo ezivele ze-decarburization zibuyela kancane kancane kokuqukethwe kwekhabhoni yasekuqaleni, amandla ekhabhoni asethwe ku-0.42% 0.48% oncomekayo, ama-nanotubes kanye nezinga lokushisa elicisha ukushisa, okufanayo akukwazi ngaphansi kwezinga lokushisa eliphezulu, ukuze kugwemeke amaholo. okusanhlamvu, kuthinta izakhiwo zemishini.Izinkinga zekhwalithi eziyinhloko zezinsimbi ekucimeni nasekucimeni inqubo yilezi: ukucisha ubulukhuni abanele;Ukuqina kokuqina okungalingani;Ukucima i-deformation overshoot;Ukucisha ukuqhekeka.Izinkinga ezinjalo ensimini zivame ukuhlotshaniswa nezinto ezingavuthiwe, ukucisha ukushisa nokucisha ukupholisa. Ukwakhiwa okulungile kwenqubo yokwelapha ukushisa kanye nokumiswa kwenqubo yokusebenza kokukhiqiza ngokuvamile kungagwema izingozi zekhwalithi ezinjalo.
