Ngokuqhelekileyo, intloko ye-bolt yenziwa ngokulungiswa kweplastiki, xa kuthelekiswa nokusika, i-fiber yensimbi (i-metal wire) kunye nemilo yemveliso iyaqhubeka, ngaphandle kokusika phakathi, ephucula amandla emveliso, ngakumbi imveliso. iipropathi ezigqwesileyo zoomatshini.Inkqubo yokubumba isihloko esibandayo ibandakanya ukusika kunye nokwenza, ukucofa okukodwa, kabini -cofa isihloko esibandayo kunye nemulti - isikhundla sesihloko esizenzekelayo esibandayo.Umatshini wesihloko obandayo ozenzekelayo usetyenziselwa isitampu, ukuphazamisa, ukukhupha kunye nokunciphisa i-diameter kwiifom ezininzi zokubumba. .Simplex bit okanye multi-isikhululo oluzenzekelayo umatshini isihloko abandayo usebenzisa iimpawu processing of ongenanto yantlandlolo yenziwe ubungakanani impahla 5 ukuya 6 yeemitha bar ubude okanye ubunzima 1900-2000 kg yobungakanani yocingo intonga ngocingo lwentsimbi, processing. itekhnoloji ziimpawu zokubumba isihloko esibandayo asiloshiti elisikiwe lingenanto ngaphambili, kodwa USEBENZISA umatshini wesihloko obandayo ozenzekelayo ngokwawo ngebha kunye nocingo lwentsimbi yocingo.ukusika kunye nokuphazamisa indawo engenanto (ukuba kuyimfuneko) .Ngaphambi kwe-extrusion cavity, indawo engenanto kufuneka ihlaziywe.I-blank ingafumaneka ngokubunjwa.I-blank ayifuni ukubunjwa ngaphambi kokuphazamiseka, ukunciphisa i-diameter kunye nokucinezela.Emva kokuba i-blank inqunyulwe. ithunyelwa kwisikhululo somsebenzi esiphazamisayo.Esi sikhululo sinokuphucula umgangatho wesithuba esingenanto, sinciphise amandla okwenza isikhululo esilandelayo nge-15-17%, kwaye sandise ubomi bokubumba. Ukukhethwa kwendlela yokwenza kunye nenkqubo esetyenzisiweyo.Ukongezelela, kuxhomekeke kwakhona kwiimpawu zesakhiwo sezixhobo ezisetyenzisiweyo, iimpawu zenkqubo kunye nombuso wazo, ukuchaneka kwesixhobo, ubomi kunye neqondo lokunxiba.Ngokwentsimbi ephezulu ye-alloy esetyenziswa kwisihloko esibandayo kunye ne-extrusion, uburhabaxa bomphezulu wokusebenza we-alloy eqinileyo die akufunekanga ibe yi-Ra=0.2um, xa uburhabaxa bomphezulu wokusebenza wezo kufa bufikelela ku-Ra=0.025-0.050um, inobomi obuninzi.
Intambo yebholithi idla ngokucutshungulwa yinkqubo ebandayo, ukwenzela ukuba i-screw screw ngaphakathi kobubanzi obuthile iqengqeleke ngepleyiti yomsonto (fa), kwaye intambo yenziwa ngoxinzelelo lwepleyiti yentambo (fa) .Isetyenziswa kakhulu ngenxa yokuba i-plastic streamline ye-screw thread ayinqunyulwanga, amandla anyukile, ukuchaneka kuphezulu kwaye umgangatho ufana.Ukuze uvelise intambo ngaphandle kwedayamitha yemveliso yokugqibela, ububanzi obufunekayo bomsonto ongenanto buhlukile, ngenxa yokuba inqunyulwe ngokuchaneka kwentambo, nokuba i-coating yempahla kunye nezinye izinto. ipleyiti yocingo yokuqengqeleka) bafe, elinye icala ukuba extrude iqokobhe cylindrical, elinye icala ukwenza ukujikeleza iqokobhe, ukuqengqeleka yokugqibela kufa kwimilo conical idluliselwe kwiqokobhe, ukuze intambo forming.Rolling (rub) uxinzelelo intambo processing ingongoma eqhelekileyo kukuba inani revolution rolling ayikho kakhulu, ukuba kakhulu, ukusebenza kakuhle liphantsi, umphezulu amazinyo intambo lula ukuvelisa ukwahlukana okanye buckle ngocwangco phenomenon. Ngokuchaseneyo, ukuba inani revolutions kakhulu. encinci, intambo ububanzi kulula ukulahlekelwa isangqa, ukuqengqeleka uxinzelelo ukwanda engaqhelekanga kwinqanaba lokuqala, okukhokelela kufa life.Iziphene eziqhelekileyo umsonto rolling: ezinye iintanda umphezulu okanye imikrwelo kumsonto; .Ukuba ezi ziphene zenzeke kuManani amakhulu, ziya kufumaneka kwinqanaba lokucubungula.Ukuba inani elincinci lezi ziphene zenzeke, inkqubo yokuvelisa ayiyi kuqaphela ezi ziphene ziya kugeleza kumsebenzisi, zibangele ingxaki.Ngoko ke, imiba ephambili ye iimeko zokusetyenzwa kufuneka zishwankathelwe ukulawula ezi zinto zibalulekileyo kwinkqubo yemveliso.
Izibophelelo zamandla aphezulu ziya kuthotywa kwaye zithotywe ngokweemfuno zobugcisa. Injongo yonyango lobushushu kunye nokufudumeza kukuphucula iimpawu zoomatshini ezibanzi zeziqhoboshi ukuze zihlangabezane nexabiso elichaziweyo lamandla okuqina kunye nomlinganiselo wamandla okugoba. Itekhnoloji yonyango lobushushu inempembelelo ebalulekileyo kwisixhobo umgangatho wangaphakathi we-fasteners ephezulu, ngakumbi umgangatho wayo wangaphakathi.Ngoko ke, ukwenzela ukuvelisa iziqhoboshi ezikumgangatho ophezulu, kuyimfuneko ukuba nezixhobo zeteknoloji yonyango olushushu oluphezulu.Ngenxa yomthamo omkhulu wemveliso kunye nexabiso eliphantsi leebholiti zamandla aphezulu, kunye nesakhiwo esichanekileyo nesichanekileyo. intambo yesikrufu, isixhobo sonyango lobushushu siyafuneka ukuba sibe nomthamo omkhulu wokuvelisa, inqanaba eliphezulu lokuzisebenzela kunye nomgangatho olungileyo wonyango lobushushu.Ukusukela ngeminyaka yoo-1990, umgca wokuvelisa ubushushu obuqhubekayo kunye nomoya wokukhusela ubukwindawo ebalaseleyo.Uhlobo umothuko-bottom kunye net-ibhanti eziko zifaneleke ngokukodwa unyango ubushushu kunye nokufutha kwe-fasteners ezincinci kunye nobukhulu obuphakathi.Umgca we-Tempering ngaphandle kwesithando somlilo otywiniweyo ulungile, kodwa unomoya ophezulu, ubushushu, kunye nenkqubo yeeparameters ulawulo lwekhompyuter, i-alamu yokungaphumeleli kwezixhobo kunye nemisebenzi yokubonisa.Izibophelelo eziphezulu zokuqina zisebenza ngokuzenzekelayo ukusuka ekutyeni - ukucoca - ukufudumeza - ukucima - ukucoca - ukufudumala - ukufaka imibala kwi-intanethi ngaphandle kwe-intanethi, ngokufanelekileyo ukuqinisekisa umgangatho wonyango lobushushu.I-decarburization ye-screw thread iya kubangela ukuba isiqhoboshi sihambe kuqala xa sisilela ukuhlangabezana nokumelana neemfuno zokusebenza koomatshini, nto leyo eya kwenza ukuba isiqhoboshi se-screw siphulukane nokusebenza kwaye sinciphise ubomi benkonzo. Izinto ekrwada decarbonization umaleko deepened.Ngexesha lokucinywa kunye nobushushu unyango ubushushu, ezinye iigesi oxidizing are usua.Umhlwa wentsimbi yentsimbi okanye intsalela kwingcingo emva komzobo obandayo uya kubola emva kokufudumeza eziko, ukuvelisa igesi ene-oxidizing. i-iron carbonate kunye ne-hydroxide, emva kokuba ubushushu buya kuphulwa kwi-CO ₂ kunye ne-H ₂ O, ngaloo ndlela kwandisa i-decarburization. iqondo lobushushu phakathi 700 kunye 800 degrees Celsius. Kuba uncamathiselo phezu komhlaba ucingo intsimbi ukubola kwaye idibanisa carbon dioxide kunye namanzi ngesantya ekhawulezayo phantsi kweemeko ezithile, ukuba umnatha okuqhubekayo ibhanti eziko ulawulo lwegesi ayifanelekanga, kuya kubangela kwakhona Impazamo ye-screw decarbonization.Xa ibholiti yokuqina okuphezulu inentloko ebandayo, imathiriyeli ekrwada kunye ne-annealed decarburizing layer ayisekho nje kuphela, kodwa ikhutshelwe phezulu kumsonto,okubangela ukuncitshiswa kweempawu zoomatshini (ingakumbi amandla kunye nokumelana ne-abrasion) kumphezulu we-fasteners ekufuneka ziqiniswe.Ukongezelela, i-decarburization yendawo yocingo lwentsimbi, umphezulu kunye nentlangano yangaphakathi iyahluka kwaye ine-coefficient yokwandiswa eyahlukileyo, ukucima kunokuvelisa iintanda zomhlaba. .Ngoko ke, ukukhusela intambo phezulu decarburization ekucimeni ubushushu, kodwa izinto ekrwada iye ngokuphakathi caated carbon decarburization of fasteners, ukuguqula inzuzo umnatha ibhanti eziko lokhuselo umoya kwisiseko ilingana kumxholo carbon yokuqala. kunye neendawo zokugquma ikharbhon, sele decarburization fasteners ngokucothayo ubuyela kumxholo carbon yokuqala, amandla carbon iseti kwi 0.42% 0.48% ecebisekayo, nanotubes kunye nokucima ubushushu ubushushu, efanayo ayikwazi phantsi kobushushu obuphezulu, ukwenzela ukuphepha iinkozo ezirhabaxa, kuchaphazela mechanical iipropathi.Iingxaki eziphambili zomgangatho we-fasteners ekucimeni nasekucimeni inkqubo are: ukucima ubulukhuni akwanelanga;Ubunzima bokuqina obungalinganiyo;Ukucima i-deformation overshoot;Ukucima ukuqhekeka.Iingxaki ezinjalo entsimini zihlala zihambelana nezinto ezikrwada, ukucima ukufudumeza kunye nokucima ukupholisa.Ukuqulunqwa okuchanekileyo kwenkqubo yokunyanga ubushushu kunye nokubekwa emgangathweni kwenkqubo yokusebenza kwemveliso kaninzi kunokuphepha iingozi zomgangatho onjalo.
