Ukugaya yindlela yokugqiba esetyenziswa ngokuqhelekileyo kwindawo yokutywinwa kwee-valve kwinkqubo yokuvelisa. Ukusila kunokwenza umphezulu wokutywina wevalve ufumane ukuchaneka okuphezulu komgangatho, uburhabaxa bemilo yejometri kunye noburhabaxa bomphezulu, kodwa akunakuphucula ukuchaneka kwendawo ehambelanayo phakathi komphezulu wokutywina. Ukuchaneka kwedimensional yendawo yokutywina ivalve yomhlaba idla ngokuba yi-0.001 ~ 0.003mm; ukuchaneka kwemilo yejometri (efana nokungalingani) yi-0.001mm; uburhabaxa bomphezulu yi 0.1~0.008.
Umgaqo osisiseko wokutywinwa kokugaya umphezulu uquka iinkalo ezintlanu: inkqubo yokugaya, intshukumo yokugaya, isantya sokugaya, uxinzelelo lokugaya kunye nesibonelelo sokugaya.
1. Inkqubo yokugaya
Isixhobo sokugaya kunye nomphezulu wendandatho yokutywina idibaniswe kakuhle, kwaye isixhobo sokugaya senza ukunyakaza okuyinkimbinkimbi kunye nommandla odibeneyo. Iibrasives zibekwe phakathi kwesixhobo sokunxiba kunye nomphezulu weringi yokutywina. Xa isixhobo sokunxiba kunye nomphezulu weringi yokutywina zihamba ngokuzalana kwenye, inxalenye yeenkozo ezirhabaxa kwi-abrasive iya kutyibilika okanye iqengqeleke phakathi kwesixhobo sokubopha kunye nomphezulu weringi yokutywina. umaleko wentsimbi. Iincopho ezikumphezulu weringi yokutywina ziqala phantsi, kwaye emva koko ijometri efunekayo iyafezekiswa ngokuthe ngcembe.
Ukugaya akusiyo kuphela inkqubo yomatshini yee-abrasives kwiintsimbi, kodwa kunye nesenzo sekhemikhali. Igrisi kwi-abrasive inokwenza ifilimu ye-oxide ebusweni ukuba iqhutywe, ngaloo ndlela ikhawuleza inkqubo yokugaya.
2 . intshukumo yokusila
Xa isixhobo sokusila kunye nomphezulu wekhonkco lokutywina zihamba ngokuzalana kwenye, isixa seendlela zokutyibilika kwindawo nganye kumphezulu wekhonkco lokutywina kwisixhobo sokusila kufuneka sifane. Kwakhona, isalathiso sentshukumo ehambelanayo kufuneka sihlale sitshintsha. Ukutshintsha rhoqo kwesalathiso sokunyakaza kuthintela ukhozo ngalunye lwe-abrasive ukuba luphindaphinde i-trajectory yayo phezu komsesane wokutywina, ukuze ungabangeli iimpawu ezicacileyo zokunxiba kunye nokwandisa uburhabaxa bomphezulu weringi yokutywina. Ukongezelela, utshintsho oluqhubekayo lwesalathiso sokunyakaza alukwazi ukwenza i-abrasive isasazwe ngokulinganayo, ukwenzela ukuba isinyithi esiphezu kwendandatho yokutywina sinokunqunyulwa ngakumbi.
Nangona intshukumo yokugaya iyinkimbinkimbi kwaye isalathiso sokunyakaza sitshintsha kakhulu, ukunyakaza kokugaya kuhlala kuqhutyelwa kunye nomgangatho wokudibanisa isixhobo sokugaya kunye nomphezulu wendandatho yokutywina. Ingaba i-manual grinding okanye i-mechanical grinding, ukuchaneka kwemilo yejometri yendawo yokutywina ichaphazeleka kakhulu ngokuchaneka kwemilo yejometri yesixhobo sokugaya kunye nokunyakaza kokugaya.
3. isantya sokusila
Ukukhawuleza kwentshukumo yokusila, ngokufanelekileyo ukugaya. Isantya sokugaya sikhawuleza, amaqhekeza amaninzi abrasive adlula kumphezulu we-workpiece ngexesha leyunithi, kwaye isinyithi esingaphezulu sinqunywe.
Isantya sokusila sidla ngokuba yi-10 ~ 240m/min. Kwizixhobo zokusebenza ezifuna ukuchaneka okuphezulu kokusila, isantya sokugaya ngokuqhelekileyo asidluli kwi-30m / min. Isantya sokugaya indawo yokutywinwa kwevalve ihambelana nempahla yendawo yokutywina. Isantya sokugaya indawo yokutywinwa kobhedu kunye nentsimbi yentsimbi yi-10 ~ 45m / min; indawo yokutywina yentsimbi eqinile kunye ne-alloy eqinile yi-25 ~ 80m / min; indawo yokutywina ye-austenitic stainless steel 10 ~ 25m / min.
4. uxinzelelo lokugaya
Ukusebenza kokugaya kuyanda ngokunyuka koxinzelelo lokugaya, kwaye uxinzelelo lokugaya akufanele lube lukhulu, ngokubanzi i-0.01-0.4MPa.
Xa ugaya indawo yokutywina yentsimbi, ubhedu kunye ne-austenitic stainless steel, uxinzelelo lokugaya ngu-0.1 ~ 0.3MPa; indawo yokutywina yentsimbi eqinile kunye ne-alloy eqinile yi-0.15 ~ 0.4MPa. Thatha ixabiso elikhulu lokusila ngokurhabaxa kunye nexabiso elincinci lokugaya kakuhle.
5. Isibonelelo sokusila
Ekubeni ukugaya kuyinkqubo yokugqiba, inani lokusika lincinci kakhulu. Ubungakanani besibonelelo sokugaya buxhomekeke ekuchanekeni komatshini kunye nobunzima bomhlaba benkqubo yangaphambili. Ngaphantsi kwesiseko sokuqinisekisa ukukhutshwa kweendlela zokucutshungulwa kwenkqubo yangaphambili kunye nokulungisa impazamo yejometri yendandatho yokutywina, encinci isibonelelo sokugaya, kungcono.
Umphezulu wokutywina kufuneka ucolwe kakuhle phambi kokuba ucolwe. Emva kokugaya okulungileyo, indawo yokutywina inokugqithwa ngokuthe ngqo, kwaye isibonelelo esincinci sokusila kukuba: isibonelelo sobubanzi yi-0.008 ~ 0.020mm; Isibonelelo senqwelomoya yi-0.006 ~ 0.015mm. Thatha ixabiso elincinci xa ukugaya ngesandla okanye ukuqina kwezinto eziphathekayo kuphezulu, kwaye uthathe ixabiso elikhulu xa ukugaya oomatshini okanye ubunzima bezinto eziphantsi.
Umphezulu wokutywina womzimba wevalvu awukho lula ukuba uphantsi kwaye uqhutywe, ngoko ke ukujika okucolekileyo kungasetyenziswa. Emva kokugqiba ukujika, umphezulu wokutywina kufuneka ube ngumhlaba orhabaxa phambi kokugqiba, kwaye isibonelelo senqwelomoya yi-0.012 ~ 0.050mm.
Ivalve yaseTianjin tanggu yamanzi-seal Co., Ltd yayicaciswe kwimvelisoivalve ehleli ibhabhathane eyomelelayo, ivalve yesango, Y-isihluzi, ivalve yokulinganisa, ivalve yokujonga iwafer, njl.
