Daawaynta Dusha sare ee Xidhashada aan sinnayn ee Roolaha Carbide Stud

Marka loo eego habka xirashada ee dusha sare ee rullaluistemadka ee rullaluistemadka cadaadis sare, dusha rullaluistemadka sibidhka istuudka carbide ayaa la sameeyay sannadihii la soo dhaafay. Dhululubada ay ku duugan tahay tungsten-cobalt kaarbiide sibidhku waxa uu ku xidhan yahay jidhka gacma-gacmeedka si uu u sameeyo weji adag oo adag ilaa HRC67. Farqiga u dhexeeya urka iyo waxaa ka buuxsamay qaybo ganaax ah oo ku jira maaddada, sidaas darteed samaynta xadhkaha alaabta si ay u ilaaliso waalidka gacan-galka ah. Dusha sare ee stud waxay leedahay faa'iidooyinka caabbinta xidhashada wanaagsan, nolol adeeg oo hal mar ah, culays yar oo shaqo oo maalinle ah, waxaana lagu dabaqay warshado badan.

Sababaha xirashada aan sinnayn ee dusha sare ee rullaluistuyada:

Sababtoo ah saamaynta cidhifka ah ee rullaluistemadka cadaadiska sare, cadaadiska extrusion ee dhexda rullaluistemadka waa ka weyn yahay labada daraf marka walxaha la tuujiyo. Waqti ka dib, xirashada dhexda dusheeda duubka ayaa si aad ah uga khatarsan kan labada daraf (sawirka 1). Marxaladda dambe ee xidhashada, farqiga u dhexeeya labada rollers waa mid aad u weyn si ay u sameeyaan lakabka wax, iyo saamaynta extrusion ee mishiinka rullaluistemadka sare waa ka sii daran, iyo farqiga dhexdhexaadka ah oo kaliya waa la dhimi karaa by hagaajinta farqiga duudduuban asalka ah. labada rollers. Sababtoo ah xirashada yar ee labada daraf, wejiyada dhamaadka ee labada rollers ayaa isku dhici doona marka la hagaajiyo ilaa xad, iyo shuruudaha samaynta lakabka walxaha dhexdhexaadka ah weli lama buuxin, sidaas darteed saameynaya tayada sare ee rullaluistemadka alaabta iyo xasiloonida qalabka.

Dusha sare ee rullaluistemadka dusha sare ee dhaqameed waxay hagaajin kartaa aagga dusha sare ee rullaluistuyada si loo daboolo baahiyaha wax soo saarka. Dusha rullaluistuantu waa dherer gaar ah oo ka samaysan carbide cemented cylindrical sibidhka gundhig godka cylindrical ee alaabta saldhigga ah ee dusha rullaluistemadka si ay u buuxiyaan xoogga iyo adkaanta shuruudaha gacanta rullaluistemadka, laakiin alaabta matrix ee gacanta rullaluistemadka waa liidata ee waxqabadka alxanka. , iyo tungsten cobalt carbide cemented sibidhka loo isticmaalo ustaraatiijiyadu ma laha wax qabad dusha sare ah, markaa dusha sare ee rullaluistu wuxuu u baahan yahay inuu xalliyo dhibaatada sida loo hagaajiyo xirashada aan sinnayn ka dib xirashada dusha sare ee roller-ka.

Sababaha keenaya xidhashada sinnaanta ee dusha duubka waxaa ka mid ah hawlgal aan habboonayn, kala soocidda walxaha ee weelka miisaanka socodka joogtada ah iyo wixii la mid ah. Isticmaalayaasha qaarkood waxay hagaajiyaan qadarka gudubka ee mishiinka rullaluistuyada cadaadiska sare leh iyaga oo hagaajinaya furitaanka albaabka gacanta ee lagu dejiyay haanta socodka joogtada ah. Haddii albaabka gacanta ee dhexda ku yaal oo keliya la furo, qalab badan ayaa dhex mara rullaluistuyada dhexda, oo walxaha yar yar oo keliya ayaa dhex mara labada daraf, taasoo keentay inay xidhmaan rullaluistuyada. Kala-soocidda walxaha waxaa inta badan sababa habka aan habboonayn ee dhuumaha geeddi-socodka, taas oo keenta isku-dhafka aan ku filnayn ee maaddooyinka cusub iyo wareegga wareegga qashinka joogtada ah.

Habka daawaynta:

Waxa jira kumanaan biin ah oo tungsten-cobalt ah oo sibidh ah oo sibidhka ah oo loo isticmaalo warshado waaweyn oo cadaadis badan leh, kuwaas oo lagu hagaajin karo waxqabad xumo, mana jirto tignoolajiyada daawaynta ee qaan-gaadhka ah oo la isku halayn karo gudaha iyo dibaddaba. Haddii hufnaanta shaqada ee rullaluistemadka cadaadis sare la soo celiyo by beddelo sleeve rullaluistemadka stud, ma aha oo kaliya qaali, laakiin sidoo kale qashinka gacanta rullaluistemadka jir ah waxay keeni doontaa in qashinka ah khayraadka. Baaritaan buuxa iyo dood ka dib, waxaa la go'aamiyay in la qaato habka shiidi si loo xalliyo dhibaatada xirashada aan sinnayn ee dusha rullaluistemadka, iyo horumarinta qalabka shiidi ee dusha rullaluistemadka. Sababtoo ah booska xaddidan ee shaqada ee rullaluistemadka cadaadiska sare iyo dhibka qaadista, waxaa lagama maarmaan ah in la naqshadeeyo hab awood gaar ah oo lagu shiidi karo, qalabkuna waa inuu noqdaa mid fudud oo fudud si loo rakibo, si loo gaaro shiidi goobta. .

Qalabka wax lagu shiido rullalulatuska dusha sare wuxuu ka kooban yahay aalad lagu cabbiro xogta duuduubka ee dusha duudduuban, saxan wax lagu shiidi karo, habka awoodda wadista saxanka wax lagu shiidi karo, hab quudin oo lagu jiido saxanka shiidi iyadoo la raacayo dhidibka rullaluistemadka iyo radial dhaqdhaqaaqa iyo nidaamka xakamaynta hagaajinta tooska ah. Marka loo eego sifooyinka xirashada ee rullaluistemadka dusha sare ee stud, sifooyinka xirashada ee labada daraf ee dusha sare ee ulaha waa yar yihiin iyo xirashada dhexe waa weyn tahay, furaha si loo xalliyo dhibaatada qalabka wax lagu shiido rullaluistemadka dusha sare ee stud waa in la isku daro laba rollers. Cidhifka sare ee usarku wuu fog yahay. Si loo hagaajiyo waxtarka wax lagu shiido, qalabka wax lagu shiido waxaa loo qaabeeyey si labada daraf ee rullaluistu ay isku mar u shaqayn karaan oo madax bannaani.

Sababtoo ah adkaanta sare ee urka, saxanka wax lagu shiido ee caadiga ah wuxuu leeyahay waxtar hoose iyo khasaaro weyn. Iyada oo loo marayo tijaabooyin badan oo lagu shiidi jiray, wax-ku-oolnimada iyo wax-ku-oolnimada noocyada kala duwan ee qaybaha wax lagu shiidi karo ayaa la is barbar dhigayaa, waxaana la doortay qaab-dhismeedka xaashida ku habboon, cabbirka, nooca abrasive, cabbirka walxaha, qallafsanaanta iyo nooca xidhaha ayaa la doortay. Habka quudinta ee rullaluistemadka stud shiid waxa uu hagaajin karaa kala duwan ee wax shiida wakhtiga dhabta ah iyada oo loo marayo nidaamka xakamaynta toosan si toos ah xogta xirashada ee korka rullaluistemadka. Waqtigan xaadirka ah, qalabka wax lagu shiido waxaa loo adeegsaday warshado badan oo cadaadis-sare leh oo loogu talagalay daawaynta ka dib ee xirashada dusha sare ee biinanka.

Gabagabo:

Adkeysiga dusha sare ee rullaluistuyada, caabbinta xidhashada wanaagsan, waxay samayn kartaa xayndaabka dahaarka ah ee shaxanka gacan-gacmeedka. Si kastaba ha ahaatee, in muddada dambe ee isticmaalka, ay sabab u tahay saamaynta cidhif ee rullaluistemadka cadaadis sare iyo kala soocidda walxaha ee bin socodka joogtada ah ee miisaanka, xidhashada dusha rullaluistemadka ma labis ah, iyo sifooyinka xirashada xirashada yar ee labada daraf. Xiro weyn oo dhexda ku jira waxay saameeyaan wax-soo-saarka iyo tayada alaabada rullaluistuleyda ah ee cadaadiska sare leh. Adiga oo codsanaya qalabka wax lagu shiidi karo ee loo yaqaan 'stud roller' si uu u shiido dusha sare ee rullaluistemadka taranka ee goobta, isku mid ahaanshaha iyo saamaynta extrusion ee dusha sare ee rullaluistemadka urka ayaa dib loo soo celin karaa, nolosha adeegga ee dusha rullaluistemadka ustarad waa la kordhin karaa, iyo kharashka sare iyo qashinka khayraadka. oo ay sababto in la beddelo gacan-galka cusub waa laga fogaan karaa, si loo hagaajiyo waxtarka wax-soo-saarka iyo kaydinta kheyraadka.
