Ngokuvamile, ikhanda lomshudo lakhiwa ukucutshungulwa kwepulasitiki okubandayo, uma kuqhathaniswa nokusika, i-fiber yensimbi (i-metal wire) eduze nokuma komkhiqizo iyaqhubeka, ngaphandle kokusika phakathi, okuthuthukisa amandla omkhiqizo, ikakhulukazi izinto ezinhle kakhulu zemishini.Inqubo yokwakheka kwesihloko esibandayo ihlanganisa ukusika nokwenza, chofoza kanye - chofoza 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 usayizi wezinto ezibonakalayo 5 kuya ku-6 amamitha ubude bebha noma isisindo singu-1900-2000 kg wosayizi wentambo yensimbi yocingo, ukucutshungulwa. ubuchwepheshe yizici zokwakheka kwesihloko esibandayo akulona ishidi elisikiwe elingenalutho kusenesikhathi, kodwa LISEBENZISA umshini wesihloko obandayo ozenzakalelayo ngokwawo ngebha kanye nentambo yensimbi yocingo.ukusika nokucasula okungenalutho (uma kunesidingo).Ngaphambi kwe-extrusion cavity, okungenalutho kufanele kulungiswe kabusha.Okungenalutho kungatholakala ngokubunjwa.Okungenalutho akudingi ukubunjwa ngaphambi kokucasula, ukunciphisa ububanzi nokucindezela.Ngemva kokusikwa okungenalutho, ithunyelwa esiteshini somsebenzi esiphazamisayo.Lesi siteshi singathuthukisa ikhwalithi yokungenalutho, sinciphise amandla okwenza isiteshi esilandelayo ngo-15-17%, futhi sandise impilo yesikhunta.Ukunemba okutholakala ngokubunjwa kwesihloko esibandayo nakho kuhlobene ukukhethwa kwendlela yokwenza kanye nenqubo esetshenzisiwe.Ngaphezu kwalokho, kubuye kuncike ezicini zesakhiwo semishini esetshenzisiwe, izici zenqubo kanye nesimo sazo, ukunemba kwethuluzi, impilo kanye nedigri yokugqoka.Ngensimbi ephezulu ye-alloy esetshenziselwa isihloko esibandayo kanye ne-extrusion, ubulukhuni bendawo yokusebenza ye-hard alloy die akumele kube i-Ra=0.2um, lapho ukuhwashala kwendawo esebenzayo yefasi enjalo kufinyelela ku-Ra=0.025-0.050um, inokuphila 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. ipuleti le-wire plate) liyafa, uhlangothi olulodwa ukukhipha igobolondo eliyisilinda, olunye uhlangothi ukwenza ukuzungezisa igobolondo, ukugoqa kokugcina kufa kumumo oyiconical kudluliselwe kugobolondo, ukuze intambo yakheke.Rolling (hlikihla) intambo yokucindezelaIphuzu elivamile liwukuthi inani le-rolling revolution aliningi kakhulu, uma liningi kakhulu, ukusebenza kahle kuphansi, ingaphezulu lentambo yamazinyo kulula ukukhiqiza ukuhlukana noma i-buckle ehlelekile. Ngokuphambene nalokho, uma inani lokuvukela encane, ububanzi bentambo kulula ukulahlekelwa yindilinga, ukucindezela okugoqayo kukhuphuka okungavamile ekuqaleni, okuholela ekufeni okufushane. Amaphutha avamile entambo egoqayo: ukuqhekeka okungaphezulu noma ukuklwebheka entanjeni;Ibhande elingahlelekile; .Uma lezi ziphambeko zenzeka ngamaNombolo amakhulu, zizotholakala esigabeni sokucutshungulwa.Uma kwenzeka inani elincane lalezi zinkinga, inqubo yokukhiqiza ngeke ibone ukuthi lezi zinkinga zizogeleza kumsebenzisi, kubangele inkinga.Ngakho-ke, izinkinga ezibalulekile izimo zokucubungula kufanele zifinyezwe 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 onesimo sokuzivikela ube sendaweni evelele.Uhlobo lwe-shock-bottom kanye nesithando somlilo se-net-belt zifaneleka ngokukhethekile ekwelapheni ukushisa kanye nokushisa kwama-fasteners amancane naphakathi.Umugqa wokushisa ngaphandle kwesithando somlilo ovaliwe ukusebenza kuhle, kodwa futhi unomkhathi othuthukisiwe, izinga lokushisa, kanye nemingcele yenqubo. isilawuli sekhompiyutha, i-alamu yokuhluleka kwemishini kanye nemisebenzi yokubonisa.Izinto zokubopha ezinamandla aphezulu zisebenza ngokuzenzakalelayo kusukela ekuphakeleni - ukuhlanza - ukufudumeza - ukucisha - ukuhlanza - ukushisa - ukufaka umbala kumugqa ongaxhunyiwe ku-inthanethi, ukuqinisekisa ngempumelelo ikhwalithi yokwelashwa kokushisa.I-decarburization of screw thread kuzobangela ukuthi isibophelelo 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 e-oxidizing yi-usaa.ukugqwala kwentambo yensimbi yensimbi noma okusele ocingweni ngemva komdwebo obandayo kuzobola ngemva kokushisisa esithandweni, kukhiqize igesi ekhipha i-oxidizing. Ukugqwala kwensimbi yensimbi, isibonelo, kwenziwa i-iron carbonate ne-hydroxide, ngemva kokushisa kuzophulwa ku-CO ₂ kanye ne-H ₂ O, ngaleyo ndlela kubhebhethekise i-decarburization. Imiphumela ibonisa ukuthi i-decarburization degree ye-medium carbon alloy steel ibucayi kakhulu kune-carbon steel, kanye ne-decarburization esheshayo. izinga lokushisa liphakathi kuka-700 no-800 degrees Celsius. Ngenxa yokuthi okunamathiselwe phezu kocingo lwensimbi kuyabola futhi kuhlanganiswe ku-carbon dioxide namanzi ngesivinini esisheshayo ngaphansi kwezimo ezithile, uma i-mesh eqhubekayo yokulawula igesi yomlilo ayifaneleki, izophinde ibangele Iphutha le-screw decarbonization.Lapho ibhawodi elinamandla aphezulu linekhanda elibandayo, impahla eluhlaza kanye nongqimba lwe-annealed decarburizing akusagcini nje ngokuba khona, kodwa kudluliselwa phezulu kochungechunge,okuholela ekunciphiseni izakhiwo zemishini (ikakhulukazi amandla kanye nokumelana nokuhuzuka) ebusweni bezinsimbi ezidinga ukuqina.Ngaphezu kwalokho, i-surface decarburization yocingo lwensimbi, i-surface kanye nenhlangano yangaphakathi ihlukile futhi ine-coefficient yokwandisa ehlukene, ukucisha kungase kukhiqize ukuqhekeka kwendawo. .Ngakho-ke, ukuvikela intambo phezulu decarburization in ukushisa quenching, kodwa futhi izinto zokusetshenziswa iye ngokusesilinganisweni camera carbon decarburization of fasteners, vula inzuzo enezikhala ibhande isithando somlilo umkhathi zokuzivikela in the eziyisisekelo elilingana nokuqukethwe carbon original. kanye ne-carbon enamathela izingxenye, kakade decarburization fasteners kancane kancane emuva kokuqukethwe ikhabhoni yasekuqaleni, amandla carbon isethwe 0.42% 0.48% kuhle, nanotubes futhi quenching lokushisa lokushisa, okufanayo ayikwazi ngaphansi lokushisa eliphezulu, ukuze ugweme okusanhlamvu amaqhafuqhafu, kuthinte mechanical izakhiwo.Izinkinga zekhwalithi eziyinhloko zezinsimbi ekucimeni nasekucimeni inqubo akabusha: Ukucisha ubulukhuni abanele;Ukuqina kokuqina okungalingani;Ukucisha i-deformation overshoot;Ukucima ukuqhekeka.Izinkinga ezinjalo ensimini zivame ukuhlotshaniswa nezinto ezingavuthiwe, ukucisha ukushisa nokucisha ukupholisa.Ukwakhiwa okulungile kwenqubo yokwelashwa kokushisa kanye nokumiswa kwenqubo yokusebenza kokukhiqiza ngokuvamile kungagwema izingozi zekhwalithi ezinjalo.
