Ngokuqhelekileyo, intloko yebholithi yenziwa ngokulungiswa kweplastiki yentloko ebandayo, xa kuthelekiswa nokusika, i-fiber yensimbi (i-metal wire) kunye nemilo yemveliso iyaqhubeka, ngaphandle kokusika phakathi, okuphucula amandla emveliso, ngakumbi Iipropati ezibalaseleyo zoomatshini.Inkqubo yokubumba isihloko esibandayo iquka ukusika kunye nokwenza, ukucofa okukodwa, kabini - cofa isihloko esibandayo kunye ne-multi - isikhundla sesihloko esibandayo esizenzekelayo. .Simplex bit okanye multi-isikhululo oluzenzekelayo oluzenzekelayo umatshini isihloko ebanda usebenzisa iimpawu processing yoqobo olungenanto lwenziwe ubungakanani impahla 5 ukuya 6 yeemitha bar ubude okanye ubunzima yi 1900-2000 kg yobukhulu yocingo intonga ngocingo lwentsimbi, ukusetyenzwa. ubuchwepheshe ziimpawu zentloko ebandayo yokwenza ayilophepha elisikiweyo elingenanto ngaphambili, kodwa USEBENZISA umatshini wesihloko obandayo ozenzekelayo ngokwawo ngebha kunye nocingo lwentsimbi yocingo olusikiwe kwaye luphazamise indawo engenanto (ukuba kuyimfuneko). Ukubunjwa kwakhona.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 wezinto ezingenanto, ukunciphisa. amandla okwenza isikhululo esilandelayo nge-15-17%, kwaye andise ubomi bomngundo.Ukuchaneka okuphunyeziweyo ngokubunjwa kwesihloko esibandayo kukwanxulumene nokukhethwa kwendlela yokwenza kunye nenkqubo esetyenziswayo.Ukongezelela, kukwaxhomekeke iimpawu zesakhiwo sezixhobo ezisetyenzisiweyo, iimpawu zenkqubo kunye nemeko yazo, ukuchaneka kwesixhobo, ubomi kunye neqondo lokunxiba. Kwintsimbi ephezulu ye-alloy esetyenziswa kwisihloko esibandayo kunye ne-extrusion, uburhabaxa bokusebenza komphezulu we-alloy die akumele kube yiRa = 0.2um, xa uburhabaxa bomphezulu osebenzayo wokufa okunjalo bufikelela ku-Ra=0.025-0.050um, inobomi obuninzi.
Intambo yebholithi idla ngokucutshungulwa yinkqubo ebandayo, ukwenzela ukuba i-screw screw ngaphakathi kwedayamitha ethile iqengqeleke ngepleyiti yentambo (fa), kwaye intambo yenziwe ngoxinzelelo lwepleyiti yentambo (fa) .Isetyenziswa kakhulu ngenxa yokuba i-plastic streamline ye-screw thread ayinqunyulwanga, amandla anyukile, ukuchaneka kuphezulu kwaye umgangatho ufana. kuba inqunyanyiswa kukuchaneka kwentambo, nokuba i-coating yempahla kunye nezinye izinto. ipleyiti yocingo eqengqelekayo) 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 revolution ayikho kakhulu, ukuba kakhulu, ukusebenza kakuhle liphantsi, umphezulu amazinyo intambo lula ukuvelisa ukwahlukana okanye ngocwangco buckle phenomenon. Ngokuchaseneyo, ukuba inani revolutions lincinci kakhulu, intambo Idayamitha kulula ukuphulukana nesangqa, ukuqengqeleka koxinzelelo lokwanda okungaqhelekanga kwinqanaba lokuqala, okukhokelela kubomi obufutshane bokufa.Iziphene ezixhaphakileyo zemisonto eqengqelekayo: iintanda ezingaphezulu okanye imikrwelo kumsonto;Ibhanti engalunganga; Umsonto uphume ngobungqukuva. iziphene zenzeke kuManani amakhulu, ziya kufumaneka kwinqanaba lokucubungula.Ukuba inani elincinci lezi ziphene zenzeke, inkqubo yokuvelisa ayiyi kuqaphela ezi ziphene ziya kuhamba kumsebenzisi, zibangele ingxaki.Ngoko ke, imiba ephambili yeemeko zokucubungula kufuneka kushwankathelwa 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 ye-screw, izixhobo zokunyanga ukushisa zifunekayo ukuba zibe nomthamo omkhulu wokuvelisa, iqondo eliphezulu lokuzenzekelayo kunye nomgangatho omhle wonyango lobushushu.Ukusukela kwiminyaka yoo-1990, umgca wokuvelisa ubushushu obuqhubekayo kunye nomoya okhuselayo uye waba kwindawo ephezulu. Uhlobo umothuko-bottom kunye net-ibhanti eziko zifaneleke ngokukodwa unyango ubushushu kunye nokucaphuka 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 ukucima kunye nobushushu unyango ubushushu, ezinye iigesi oxidizing zidla ngokungeniswa evela ngaphandle furnace.The umhlwa intsimbi bar ucingo okanye intsalela ngocingo emva komzobo ebandayo uya kubola emva kokufudumeza eziko. , ukuvelisa i-oxidizing gas.I-Steel wire surface rust, umzekelo, yenziwe nge-iron carbonate kunye ne-hydroxide, emva kokuba ubushushu buya kuphulwa kwi-CO ₂ kunye ne-H ₂ O, ngaloo ndlela kwandisa i-decarburization.Iziphumo zibonisa ukuba i-decarburization degree yentsimbi ye-carbon alloy ephakathi iyingozi ngakumbi kuneyentsimbi ye-carbon, kwaye iqondo lobushushu elikhawulezayo le-decarburization liphakathi kwama-700 kunye nama-800 degrees Celsius.Ngenxa yokuba i-attachment ebusweni bocingo lwentsimbi iyabola kwaye idibanise kwi-carbon dioxide kunye namanzi ngesantya esikhawulezayo phantsi kwento ethile. iimeko, ukuba i-mesh eqhubekayo ibhanti yokulawula igesi yesithando somlilo ayifanelekanga, iya kubangela kwakhona impazamo ye-screw decarbonization.Xa i-bolt yamandla aphezulu inentloko ebandayo, i-raw material kunye ne-annealed decarburizing layer ayisekho nje kuphela, kodwa idluliselwe kwi- umphezulu womsonto, okubangela ukuba kuncitshiswe iimpawu zoomatshini (ingakumbi amandla kunye nokumelana nokuqhawuka) kumphezulu we-fasteners ekufuneka uqiniswe.Ukongezelela, i-decarburization yomgangatho wentsimbi yentsimbi, umphezulu kunye nentlangano yangaphakathi iyahluka kwaye ine-coefficient yokwandiswa eyahlukileyo, ukucima kunokuvelisa iintanda.Ngoko ke, ukukhusela intambo phezulu decarburization ekucimeni ubushushu, kodwa izinto ekrwada iye ngokuphakathi caated carbon decarburization of fasteners, jikisa inzuzo umnatha ibhanti eziko lokukhusela umoya kwisiseko esilinganayo. kumxholo wokuqala wekhabhoni kunye neenxalenye zokugquma kwekhabhoni, iifasteners esele zidecarburization zibuyela kancinci kumxholo wokuqala wekhabhoni, amandla ekhabhoni abekwe kwi-0.42% 0.48% ecetyiswayo, i-nanotubes kunye nokucima ubushushu bobushushu, okufanayo akunakuba phantsi kobushushu obuphezulu, ukuze kuphephe ukurhabaxa. iinkozo, zichaphazela iipropathi zoomatshini.Ezona ngxaki ziphambili zomgangatho weziqhoboshi ekucimeni nasekucimeni inkqubo zezi: ukucima ubulukhuni akwanelanga;Ubulukhuni obungalinganiyo;Ukucima i-deformation overshoot;Ukucima ukuqhekeka.Iingxaki ezinjalo entsimini zihlala zinxulumene nezinto ezikrwada, ukucima ukufudumeza. kunye nokucima ukupholisa. Ukuqulunqwa okuchanekileyo kwenkqubo yokunyanga ubushushu kunye nomgangatho wenkqubo yokusebenza kwemveliso kaninzi kunokuphepha iingozi zomgangatho onjalo.
