Ngokuqhelekileyo, intloko yebholithi yenziwe ngokulungiswa kweplastiki yesihloko esibandayo, xa kuthelekiswa nokusika, i-fiber yensimbi (intambo yentsimbi) kunye nokumila kwemveliso iyaqhubeka, ngaphandle kokusika phakathi, ephucula amandla emveliso, ngokukodwa iimpawu ezibalaseleyo zomatshini. Inkqubo yokwenza i-cold heading ibandakanya ukusika kunye nokwenza, ukucofa okukodwa, kabini - nqakraza isihloko esibandayo kunye ne-multi-position esetyenziswayo yokuqhuba i-heading ebandayo, i-outrunging ezenzekelayo, i-post-automatic heading. kunye nokunciphisa i-diameter kwi-dies.Simplex bits okanye isikhululo se-multi-station oluzenzekelayo oluzenzekelayo olusebenzisa umatshini we-othomathikhi engenanto yoqobo yenziwe ubungakanani bezinto ezi-5 ukuya kwi-6 yeemitha ubude bebar okanye ubunzima buyi-1900-2000 kg yobukhulu bocingo lwentsimbi yentsimbi, iteknoloji yokucubungula iimpawu zentloko ebandayo yokubumba ayikho i-cut cut sheet yase-US kodwa icwecwe elisikiweyo le-US elingenanto ngaphambili kunye nentsimbi epholileyo. kunye nokuphazamisa indawo engenanto (ukuba kuyimfuneko) .Ngaphambi kwe-extrusion cavity, into 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, sinciphise i-forcement force, i-15uld isikhululo sobomi, kunye nokwandisa i-15ld isikhululo sobomi esilandelayo. ukuchaneka okuphunyeziweyo ngokubunjwa kwesihloko esibandayo kukwanxulumene nokukhethwa kwendlela yokwenza kunye nenkqubo esetyenzisiweyo.Ukongezelela, kuxhomekeke kwakhona kwiimpawu zesakhiwo sezixhobo ezisetyenzisiweyo, iimpawu zenkqubo kunye nombuso wabo, ukuchaneka kwesixhobo, ubomi kunye nokunxiba i-degree.Kuba intsimbi ephezulu ye-alloy esetyenziswe kwisihloko esibandayo kunye nokugqithisa, uburhabaxa bomsebenzi we-alloy enzima die akufanele ibe yi-Ra = 0.2um yomgangatho wokusebenza, xa ufikelele kwi-surface esebenzayo, Ra=0.025-0.050um, inobomi obuninzi.
Umsonto webholt udla ngokucutshungulwa yinkqubo ebandayo, ukuze i-screw engenanto ngaphakathi kobubanzi obuthile iqengqeleke ngepleyiti yomsonto (fa), kwaye intambo yenziwe ngoxinzelelo lwepleyiti yentambo (fa). Isetyenziswa ngokubanzi ngenxa yokuba umgca weplastiki wentambo yesijija awunqunyulwanga, amandla anyukile, ukuchaneka kuphezulu kwaye umgangatho ufana. nokuba ukutyabeka impahla kunye nezinye izinto.Ukuqengqeleka (ukuqengqeleka) ngokucinezela intambo yindlela yokwenza amazinyo intambo nge deformation yeplastiki.Kukunye intambo kunye pitch efanayo kunye imilo conical yokuqengqeleka (ipleyiti yocingo oluqengqelekayo) die, elinye icala ukuba extrude iqokobhe cylindrical, elinye icala ukwenza ukujikeleza iqokobhe, iqokobhe lokugqibela lokufa kwiqokobhe leconical, ukumila koxinzelelo oluqhelekileyo ukugqithiselwa kwiqokobhe ukuba inani revolution rolling ayikho kakhulu, ukuba kakhulu, ukusebenza kakuhle liphantsi, umphezulu amazinyo intambo lula ukuvelisa ukwahlukana okanye ngokungacwangciswanga buckle phenomenon. Ngokuchaseneyo, ukuba inani revolutions lincinci kakhulu, intambo ububanzi kulula ukulahlekelwa isangqa, ukuqengqeleka uxinzelelo ukwanda engaqhelekanga kwinqanaba lokuqala, okukhokelela kufinyezwa intambo ubomi. i-buckle;Intambo iphuma kwi-roundness.Ukuba ezi ziphene zenzeka kuManani amakhulu, ziya kufumaneka kwinqanaba lokucubungula.Ukuba inani elincinci lezi ziphene zenzeke, inkqubo yokuvelisa ayiyi kuqaphela ezi ziphene ziya kuqukuqela kumsebenzisi, kubangela ingxaki.Ngoko ke, imiba ephambili yeemeko zokucubungula kufuneka ishwankathelwe ukulawula ezi zinto zibalulekileyo kwinkqubo yokuvelisa.
Iifasteners zamandla aphezulu ziya kuthotywa kwaye zihlanjululwe ngokweemfuno zobuchwepheshe.Injongo yonyango lobushushu kunye nokufudumeza kukuphucula iimpawu ezibanzi zoomatshini bezinto zokubopha ukuze zihlangabezane nexabiso elichaziweyo lamandla kunye nokugoba komlinganiselo. Ke ngoko, ukuze kuveliswe iziqhoboshi ezikumgangatho ophezulu, kuyafuneka ukuba ube nezixhobo zetekhnoloji yonyango oluphezulu.Ngenxa yomthamo omkhulu wemveliso kunye nexabiso eliphantsi leebholiti zokuqina, kunye nolwakhiwo olucikizekileyo noluchanekileyo lwentambo yesikrufu, izixhobo zokunyanga ubushushu ziyafuneka ukuze zibe nomthamo omkhulu wemveliso, inqanaba eliphezulu lokuzenzela kunye nomgangatho olungileyo wonyango lobushushu. isikhundla esongameleyo. Uhlobo lwe-shock-bottom kunye ne-net-belt i-furnace ifaneleka ngokukodwa kunyango lobushushu kunye nokufudumala kwe-fasteners encinci kunye ne-medium-size. umgca, ngempumelelo ukuqinisekisa umgangatho unyango ubushushu.I-decarburization ye-screw thread iya kubangela ukuba i-fastener ihambe kuqala xa ingaphumeleli ukuhlangabezana nokuchasana kweemfuno zokusebenza koomatshini, okuya kwenza i-screw fastener ilahlekelwe yintsebenzo kwaye inciphise ubomi benkonzo.Ngenxa ye-decarbonization yezinto ezikrwada, ukuba i-annealing ayifanelekanga, iya kwenza i-decarbonation ekrwada i-decarbonization kunye ne-temperature ye-decarbonization yonyango. Iigesi zivame ukungeniswa zivela ngaphandle kwesithando somlilo. Umhlwa wentsimbi yentsimbi okanye intsalela kwintambo yocingo emva komzobo obandayo uya kubola emva kokufudumeza eziko, ukuvelisa i-oxidizing gas. decarburization.Iziphumo zibonisa ukuba iqondo decarburization medium carbon ingxubevange yentsimbi inzulu ngaphezu carbon steel, kwaye ubushushu decarburization fastest phakathi 700 kunye 800 degrees Celsius.Ngenxa yokuba uncamathiselo phezu komhlaba ucingo lwentsimbi ukubola kwaye idibanisa ibe carbon dioxide kunye namanzi ngesantya ekhawulezayo phantsi kweemeko ezithile, ukuba ulawulo oluqhubekayo lubangela ukuba i-screw screw iya kuba yi-screw eqhubekayo, ukuba i-screw screw iya kuba yi-screw eqhubekayo. Impazamo.Xa ibholiti ephezulu yamandla ibanda, izinto ezikrwada kunye ne-annealed decarburizing layer ayisekho nje kuphela, kodwa idluliselwe kumphezulu womsonto, okukhokelela ekunciphiseni iipropathi zoomatshini (ingakumbi amandla kunye nokumelana ne-abrasion) kumphezulu we-fasteners ezifuna ukuqina. Ukongeza, i-decarburization yomphezulu we-decarburization yomgangatho ohlukeneyo kunye ne-expansienchi yentsimbi yangaphakathi inokuba ne-expansioning yentsimbi yangaphakathi kunye nolwandiso lwentsimbi yangaphakathi. ukuvelisa umphezulu iintanda.Ngoko, ukukhusela intambo phezulu decarburization ekucimeni ubushushu, kodwa nezinto ekrwada iye ngokwemodaretyathwe ikhabhoni decarburization of fasteners, ujike inzuzo umnatha ibhanti eziko olukhuselayo umoya kwisiseko ilingana isiqulatho carbon yoqobo kunye neenxalenye zokwaleka carbon, sele decarburization iseti fasteners 0% carbon enokubakho, 0 umva 0 0 . i-nanotubes kunye nokucima ubushushu bokushisa, okufanayo akunakukwazi phantsi kobushushu obuphezulu, ukuze kuthintelwe iinkozo ezirhabaxa, kuchaphazela iipropathi zoomatshini. Iingxaki eziphambili zomgangatho we-fasteners kwinkqubo yokucima kunye nokucima: akwanelanga ukucima ubulukhuni; Ubunzima obungalinganiyo; Ukucima i-deformation overshoot. kunye nokucima ukupholisa. Ukuqulunqwa okuchanekileyo kwenkqubo yokunyanga ubushushu kunye nomgangatho wenkqubo yokusebenza kwemveliso kaninzi kunokuphepha iingozi zomgangatho onjalo.
