Uphando ngeNkqubo yoMatshini weGraphite 2

Kwi-graphite machining ekhawulezayo, ngenxa yobunzima bezinto ze-graphite, ukuphazamiseka kokwakheka kwe-chip kunye nempembelelo yeempawu zokusika ngesantya esiphezulu, uxinzelelo lokusika olutshintshanayo lwenziwa ngexesha lenkqubo yokusika kwaye kwenziwa ukungcangcazela okuthile okunempembelelo, kwaye isixhobo sithambekele ekutsaleni ubuso nobuso becala. I-Abrasion ichaphazela kakhulu ubomi benkonzo yesixhobo, ngoko ke isixhobo esisetyenziselwa i-graphite machining ekhawulezayo sifuna ukumelana nokuguguleka okuphezulu kunye nokumelana nokuguguleka.

Izixhobo ezigqunywe ngedayimani zineengenelo zobulukhuni obuphezulu, ukumelana nokuguguleka okuphezulu, kunye nomlinganiselo ophantsi wokungqubana. Okwangoku, izixhobo ezigqunywe ngedayimani zezona zilungileyo zokucubungula igrafiti.

Izixhobo zoomatshini bokusika igrafiti nazo kufuneka zikhethe i-engile yejiyometri efanelekileyo, enceda ekunciphiseni ukungcangcazela kwezixhobo, ukuphucula umgangatho woomatshini, kunye nokunciphisa ukuguguleka kwezixhobo. Uphando lweengcali zaseJamani malunga nendlela yokusika igrafiti lubonisa ukuba ukususwa kwegrafiti ngexesha lokusika igrafiti kunxulumene kakhulu ne-engile yerakhi yesixhobo. Ukusika i-engile yerakhi engalunganga kwandisa uxinzelelo lokucinezela, oluluncedo ekukhuthazeni ukutyunyuzwa kwezinto, ukuphucula ukusebenza kakuhle kokucubungula, kunye nokuthintela ukuveliswa kweziqwenga zegrafiti ezinkulu.

Iindidi zezixhobo eziqhelekileyo zokusika ngesantya esiphezulu segrafiti ziquka ii-end mills, ii-ball-end cutters kunye nee-fillet milling cutters. Ii-end mills zihlala zisetyenziselwa ukucubungula umphezulu ngemigangatho kunye neemilo ezilula. Ii-ball-end milling cutters zizixhobo ezifanelekileyo zokucubungula iindawo ezigobileyo. Ii-fillet milling cutters zineempawu zee-ball-end cutters kunye nee-end mills, kwaye zingasetyenziselwa zombini iindawo ezigobileyo nezithe tyaba. Ukucubungula.

Iiparamitha zokusika

Ukukhethwa kweeparamitha zokusika ezifanelekileyo ngexesha lokusika ngesantya esiphezulu segrafiti kubaluleke kakhulu ekuphuculeni umgangatho kunye nokusebenza kakuhle kwezixhobo zomsebenzi. Ekubeni inkqubo yokusika ye-graphite machining ngesantya esiphezulu inzima kakhulu, xa ukhetha iiparamitha zokusika kunye namaqhinga okucubungula, kufuneka uqwalasele ulwakhiwo lwezixhobo zomsebenzi, iimpawu zezixhobo zomatshini, izixhobo, njl. Kukho izinto ezininzi, ezixhomekeke kakhulu kwinani elikhulu leemvavanyo zokusika.

Kwizinto zegrafiti, kuyimfuneko ukukhetha iiparameter zokusika ezinesantya esiphezulu, ukutya okukhawulezayo, kunye nesixhobo esikhulu kwinkqubo yokugaya erhabaxa, nto leyo enokuphucula ngempumelelo ukusebenza kakuhle kokugaya; kodwa kuba igrafiti ithambekele ekuqhekekeni ngexesha lenkqubo yokugaya, ingakumbi emaphethelweni, njl. Indawo kulula ukuyenza ibe yimo egobileyo, kwaye isantya sokutya kufuneka sincitshiswe ngokufanelekileyo kwezi ndawo, kwaye akufanelekanga ukutya imela eninzi.

Kwiindawo zegrafiti ezinodonga olubhityileyo, izizathu zokuqhekeka kwemiphetho kunye neekona zibangelwa ikakhulu kukungqubana kokusika, ukuvumela imela kunye nemela elastiki, kunye nokuguquguquka kwamandla okusika. Ukunciphisa amandla okusika kunokunciphisa imela kunye nemela yeebhulethi, kuphucule umgangatho wokucubungula umphezulu weendawo zegrafiti ezinodonga olubhityileyo, kwaye kunciphise ukuqhekeka nokuqhekeka kweekona.

Isantya se-spindle seziko lokugaya elikhawulezayo le-graphite ngokubanzi sikhulu. Ukuba amandla e-spindle esixhobo somatshini avumela, ukukhetha isantya esiphezulu sokusika kunokunciphisa ngempumelelo amandla okusika, kwaye ukusebenza kakuhle kokucubungula kunokuphuculwa kakhulu; kwimeko yokukhetha isantya se-spindle, Ubungakanani bokutya ngezinyo ngalinye kufuneka buhlengahlengiswe kwisantya se-spindle ukuthintela ukutya okukhawulezayo kakhulu kunye nesixhobo esikhulu esinokubangela ukuqhekeka. Ukusika i-graphite kudla ngokwenziwa kwisixhobo somatshini esikhethekileyo se-graphite, isantya somatshini ngokubanzi si-3000 ~ 5000r/min, kwaye isantya sokondla ngokubanzi si-0.5~1m/min, khetha isantya esiphantsi sokulungisa i-rough machining kunye nesantya esiphezulu sokugqiba. Kwiziko zokulungisa i-graphite ngesantya esiphezulu, isantya sesixhobo somatshini siphezulu, ngokubanzi siphakathi kwe-10000 kunye ne-20000r/min, kwaye izinga lokondla ngokubanzi liphakathi kwe-1 kunye ne-10m/min.

IZiko loMatshini weGraphite High Speed

Uthuli oluninzi luveliswa ngexesha lokusikwa kwegrafiti, nto leyo engcolisa okusingqongileyo, ichaphazela impilo yabasebenzi, kwaye ichaphazela izixhobo zoomatshini. Ke ngoko, izixhobo zomatshini wokucubungula igrafiti kufuneka zixhotyiswe ngezixhobo ezilungileyo zokuthintela uthuli kunye nokususa uthuli. Ekubeni igrafiti ingumzimba oqhubayo, ukuze kuthintelwe uthuli lwegrafiti oluveliswa ngexesha lokucubungula ukuba lungangeni kwiindawo zombane zesixhobo somatshini kwaye lubangele iingozi zokhuseleko ezifana neesekethe ezimfutshane, iindawo zombane zesixhobo somatshini kufuneka zikhuselwe njengoko kufuneka.

Iziko loomatshini bokugaya elisebenzisa i-graphite lisebenzisa i-spindle yombane ekhawulezayo ukuze lifikelele kwisantya esiphezulu, kwaye ukunciphisa ukungcangcazela kwesixhobo somatshini, kuyimfuneko ukuyila isakhiwo esisezantsi somxhuzulane. Indlela yokutya ikakhulu isebenzisa ukudluliselwa kwezikrufu zebhola ezikhawulezayo nezichanekileyo, kwaye iyila izixhobo zokulwa nothuli [7]. Isantya se-spindle seziko loomatshini bokugaya elisebenzisa i-graphite sidla ngokuba phakathi kwe-10000 kunye ne-60000r/min, isantya se-feed singafikelela kwi-60m/min, kwaye ubukhulu bodonga lokucubungula bunokuba ngaphantsi kwe-0.2 mm, umgangatho wokucubungula umphezulu kunye nokuchaneka kokucubungula kwamalungu kuphezulu, eyona ndlela iphambili yokufezekisa ukusebenza kakuhle kunye nokuchaneka kokucubungula i-graphite okwangoku.

Ngenxa yokusetyenziswa ngokubanzi kwezixhobo zegrafiti kunye nophuhliso lwetekhnoloji yokucubungula igrafiti ekhawulezayo, izixhobo zokucubungula igrafiti ezisebenza kakuhle ekhaya nakwamanye amazwe ziye zanda kancinci kancinci. Umfanekiso 1 ubonisa amaziko okulungisa igrafiti enziwa ngabavelisi basekhaya nabangaphandle.

I-GR400 ye-OKK isebenzisa uyilo oluphantsi lwesakhiwo somxhuzulane kunye nebhulorho ukunciphisa ukungcangcazela koomatshini besixhobo somatshini; isebenzisa isikhokelo se-screw kunye ne-roller esichanekileyo se-C3 ukuqinisekisa ukukhawuleziswa okuphezulu kwesixhobo somatshini, ukunciphisa ixesha lokucubungula, kunye nokongeza izikhuselo ze-splash. Uyilo lwesinyithi oluvaliweyo olupheleleyo lwesigqubuthelo esiphezulu somatshini luthintela uthuli lwegrafiti. Amanyathelo okumelana nothuli athathwe yiHaicheng VMC-7G1 ayisiyondlela esetyenziswa rhoqo yokucoca nge-vacuum, kodwa yindlela yokuvala ikhethini yamanzi, kwaye kufakwe isixhobo esikhethekileyo sokwahlula uthuli. Iindawo ezihambayo ezifana neereyile zesikhokelo kunye neentonga ze-screw nazo zixhotyiswe ngeesheaths kunye nesixhobo esinamandla sokukrwela ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwesixhobo somatshini.

Kuyabonakala kwiiparameter zeenkcukacha zeziko loomatshini be-graphite elikhawulezayo kwiTheyibhile 1, ukuba isantya se-spindle kunye nesantya sokutya kwesixhobo somatshini sikhulu kakhulu, nto leyo ephawuleka kwi-graphite ekhawulezayo yoomatshini. Xa kuthelekiswa namazwe angaphandle, amaziko oomatshini be-graphite asekhaya awanamahluko mkhulu kwiinkcukacha zezixhobo zomatshini. Ngenxa yokuhlanganiswa kwezixhobo zomatshini, iteknoloji kunye noyilo, ukuchaneka koomatshini bezixhobo zomatshini kuphantsi kakhulu. Ngokusetyenziswa ngokubanzi kwe-graphite kushishino lokuvelisa, amaziko oomatshini be-graphite akhawulezayo atsala ingqalelo engakumbi. Amaziko oomatshini be-graphite asebenza kakuhle kwaye asebenza kakuhle ayilwe kwaye enziwa. Itekhnoloji yokucubungula ephuculiweyo iyamkelwa ukunika umdlalo opheleleyo kwiimpawu zayo kunye nokusebenza kwayo ukuphucula i-graphite. Ukusebenza kakuhle kokucubungula kunye nomgangatho wamacandelo kubaluleke kakhulu ekuphuculeni itekhnoloji yokucubungula ukusika i-graphite yelizwe lam.

ukushwankathela

Eli nqaku lithetha kakhulu ngenkqubo yokwenziwa kwe-graphite ngokweempawu ze-graphite, inkqubo yokusika kunye nolwakhiwo lweziko lokwenziwa kwe-graphite ngesantya esiphezulu. Ngophuhliso oluqhubekayo lwetekhnoloji yezixhobo zomatshini kunye netekhnoloji yezixhobo, itekhnoloji yokwenziwa kwe-graphite ngesantya esiphezulu ifuna uphando olunzulu ngovavanyo lokusika kunye nezicelo ezisebenzayo ukuphucula inqanaba lobugcisa bokwenziwa kwe-graphite kwithiyori nakwindlela yokusebenza.
