Isingeniso:
Ipayipi elihlanganisiwe elingenamthungo liwuhlobo lwempahla yepayipi yensimbi enembayo ephezulu ngemva komdwebo obandayo noma ukuginqika okushisayo.Ngoba abukho ungqimba lwe-oxide ezindongeni zangaphakathi nangaphandle zepayipi lensimbi elinembile, [1] ngaphansi kwengcindezi ephezulu ngaphandle kokuvuza, ukunemba okuphezulu, ukuphela okuphezulu, ukugoba okubandayo ngaphandle kokuguqulwa, ukuvutha, ukucaba ngaphandle kokuqhekeka nokunye, isetshenziswa ikakhulukazi. ukuze kukhiqizwe izingxenye ze-pneumatic noma ze-hydraulic, njengamasilinda noma amasilinda, angenamthungo.Ukwakheka kwamakhemikhali kweshubhu ehlanganisiwe engenamthungo yi-carbon C, i-silicon Si, i-manganese Mn, isulfure S, i-phosphorus P, i-chromium Cr.
Ipayipi le-quilted nekhono lithatha ubuchwepheshe bokucubungula
Ipayipi le-quilted elingenamthungo licutshungulwa ngokugoqa.Ngenxa yengcindezi eyinsalela yokucindezela phezu kongqimba olungaphezulu, kuyasiza ukuvala imifantu emincane endaweni futhi uvimbele ukwanda kokuguguleka.Ingathuthukisa ukumelana nokugqwala okungaphezulu futhi ibambezele ukukhiqizwa noma ukunwetshwa kwemifantu yokukhathala, ukuze kuthuthukiswe amandla okukhathala kwepayipi lensimbi elivalekile.Ngokwenza ukugoqa, ungqimba oluqinile olusebenzayo olusebenzayo lwakhiwa endaweni egoqayo, okunciphisa ukuguqulwa kwe-elastic kanye nepulasitiki yendawo yokuxhumana ye-grinding pair, ngaleyo ndlela ithuthukise ukumelana nokugqokwa kodonga lwangaphakathi lwepayipi yensimbi ehlanganisiwe futhi igweme ukushiswa. okubangelwa ukugaya.Ngemuva kokugoqa, ukuncishiswa kokuqina kwendawo kungathuthukisa indawo efanelekile.
I-Rolling machining iwuhlobo lwe-chip free machining.Emazingeni okushisa ajwayelekile, i-plastic deformation yensimbi isetshenziselwa ukwenza isicaba ubulukhuni obuncane bendawo yokusebenza ukuze kufezwe inhloso yokuguqula isakhiwo esingaphezulu, izici zemishini, ukwakheka nosayizi.Ngakho-ke, le ndlela ingakwazi ukufeza izinhloso ezimbili zokupholisha nokuqinisa ngesikhathi esifanayo, engakwazi ukwenza ukugaya.
Akunandaba ukuthi hlobo luni lwendlela yokucubungula esetshenziselwa ukucubungula, kuyohlale kunezimpawu zommese eziqondile nezingalingani ebusweni bezingxenye, kanye nesimo seziqongo nezigodi ezinyakazayo,
Isimiso sokucubungula i-Rolling: Kuwuhlobo lokuphothula ingcindezi, ukusetshenziswa kwensimbi esimweni sokushisa esivamile sezimpawu zepulasitiki ezibandayo, ukusetshenziswa kwamathuluzi okugoqa ukufaka ingcindezi ethile endaweni yokusebenza, ukuze i-workpiece engaphezu kweplastiki yensimbi. geleza, ugcwalise kumkhombe wokuqala oyinsalela ophansi we-concave, futhi uzuze inani le-workpiece elibushelelezi elincishisiwe.Ngenxa yokuguquguquka kwepulasitiki yensimbi egoqekile, ukuqina kwezicubu ezingaphezulu kuyaqina kanye nokuncipha kokusanhlamvu, ukwakheka kwefiber eminyene, nokwakheka kongqimba olusele lokucindezeleka, ubulukhuni namandla, ngaleyo ndlela kuthuthukisa ukumelana nokuguga, ukumelana nokugqwala nokuhambisana kwe indawo yokusebenza.Ukugoqa kuyindlela yokwenza ipulasitiki ngaphandle kokusika.
Ipayipi le-Quilted elingenamthungo kunezinzuzo ezimbalwa:
1, thuthukisa ubulukhuni obungaphezulu, ubumahhedla bungafinyelela ku-Ra≤0.08µ m noma ngaphezulu.
2, ukujikeleza okulungile, i-elliptical ingaba ngaphansi kuka-0.01mm.
3, thuthukisa ubulukhuni bobuso, i-force deformation iyaqedwa, ubulukhuni bukhuphula i-HV≥4°
4, ngemuva kokucubungula ungqimba olusele lokucindezeleka, thuthukisa amandla okukhathala ngo-30%.
5, thuthukisa ikhwalithi yokufaneleka, unciphise ukuguga, andise impilo yesevisi yezingxenye, kodwa izindleko zokucubungula izingxenye ziyancipha.
