Umphathi wesixhobo seMeiwha HSK
Kwihlabathi lokulungiswa koomatshini elizama ukusebenza ngokugqibeleleyo kunye nokuchaneka, umnini wesixhobo se-HSK uguqula ngokuzolileyo yonke into.
Ngaba ukhe wakhathazwa yimiba yokungcangcazela kunye nokuchaneka ngexesha lokugaya ngesantya esiphezulu? Ngaba ulangazelela isixhobo esinokukhulula ngokupheleleyo ukusebenza kwesixhobo somatshini? Umnini wesixhobo se-HSK (Hollow Shank Taper) sisisombululo esichanekileyo soku.
Njengeyona nkqubo yokuphatha izixhobo zexesha lama-90s ephuhliswe yiYunivesithi yeTekhnoloji yase-Aachen eJamani kwaye ngoku ekumgangatho wamazwe ngamazwe (ISO 12164), i-HSK ngokuthe ngcembe ithatha indawo yabanini bezixhobo ze-BT zesiqhelo kwaye iye yaba lolona khetho lukhethwayo kwiinkalo zoomatshini besantya esiphezulu kunye nobuchwephesha obuphezulu.
I. Uthelekiso phakathi komphathi wesixhobo se-HSK kunye nomphathi wesixhobo se-BT sakwantu (Iingenelo ezingundoqo)
Meiwha HSK/BT Tool Holder
Eyona nto iluncedo yesibambi sesixhobo se-HSK ilele kuyilo olukhethekileyo "lomngxunya wekhowuni + nesiphelo soqhagamshelwano lobuso", oluloyisa iziphene ezisisiseko zabanini bezixhobo ze-BT/DIN kumatshini onesantya esiphezulu.
| Okukhethekileyo | Umphathi wesixhobo se-HSK | Umnini wesixhobo se-BT yesiNtu |
| Umgaqo woyilo | Ikhowuni emfutshane enomgongxo (taper 1:10) + Phelisa ubuso obunamacala amabini | Ikhowuni ende eqinileyo (i-taper 7:24) + uqhagamshelwano olucalanye lomphezulu wekhowuni |
| Indlela yokubamba | Umphezulu we-conical kunye nobuso besiphelo se-flange ngaxeshanye budibana noqhagamshelo oluphambili lwe-shaft, okukhokelela ekubekweni ngaphezulu. | Nje ngokuba nomphezulu weconical unxibelelana neshaft ephambili, yindawo enendawo enye. |
| Ukuqina kwesantya esiphezulu | Iphezulu kakhulu. Oku kungenxa yokuba amandla e-centrifugal abangela ukuba umnini wesixhobo se-HSK abambe isixhobo ngokuthe nkqi, okukhokelela ekunyuseni kokuqina kunokuncipha. | Ubuhlwempu. Amandla e-Centrifugal abangela ukuba umngxuma oyintloko we-shaft wandise kwaye umphezulu we-shank cone ukhulule (isiganeko "sokwandisa i-shaft enkulu", okukhokelela ekunciphiseni okukhulu kokuqina. |
| Ukuchaneka okuphindaphindiweyo | Iphezulu kakhulu (ngokuqhelekileyo <3 μm). Uqhagamshelwano lobuso besiphelo luqinisekisa ukuchaneka kokuma kwe-axial ephezulu kakhulu kunye ne-radial. | Ngasezantsi. Ngokudibana kwe-conical surface kuphela, ukuchaneka kuxhomekeke ekuchaphazelekeni kokugqoka kweendawo ze-conical kunye nothuli. |
| Isixhobo sokutshintsha isantya | Ngesatya esikhulu. Uyilo olufutshane lwe-conical, kunye ne-stroke emfutshane kunye nokutshintsha isixhobo esikhawulezayo. | Kancincana. Umphezulu omde we-conical ufuna i-stroke ye-pini yokutsala ixesha elide. |
| Ubunzima | Ubunzima bungaphantsi. Ulwakhiwo olungenamgongxo, olulungele ngokukodwa ukusetyenzwa kwesantya esiphezulu ekufezekiseni iimfuno zokukhanya. | Isibambi sesixhobo se-BT siqinile, ngoko sinzima. |
| Isantya sosetyenziso | Ifaneleke kakhulu kwisantya esiphezulu kunye nesantya esiphezulu sesantya esiphezulu (>15,000 RPM) | Idla ngokusetyenziselwa umatshini onesantya esisezantsi kunye nesantya esiphakathi (< 15,000 RPM) |
II. Izinto eziluncedo ezineenkcukacha zoMphathi weSixhobo se-HSK
Ngokusekwe kolu thelekiso lungentla, iinzuzo ze-HSK zinokushwankathelwa ngolu hlobo lulandelayo:
1.Ukuqina okuguquguqukayo okuphezulu kakhulu kunye nozinzo (elona ncedo lungundoqo):
Umgaqo:Xa ujikeleza ngesantya esiphezulu, amandla e-centrifugal abangela ukuba umngxuma ophambili we-shaft wande. Kubaphathi bezixhobo ze-BT, oku kukhokelela ekuncipheni kwendawo yoqhagamshelwano phakathi komphezulu we-conical kunye ne-shaft engundoqo, kwaye ibangele ukuba imiswe, ibangele ukungcangcazela, okuqhelekileyo kwaziwa ngokuba "yisixhobo sokulahla" kwaye kuyingozi kakhulu.
Isisombululo se-HSK:Ulwakhiwo olumngxuma weUmphathi wesixhobo se-HSKiya kwanda kancinane phantsi kwentshukumo yamandla e-centrifugal, kwaye iya kungena ngokuqinileyo kunye nomngxuma owandisiweyo wokusonta. Kwangaxeshanye, isiphelo soqhagamshelwano sobuso bayo siqinisekisa ukuma okuzinzile kwe-axial nakwizantya eziphezulu zokujikeleza. Olu phawu "luqina njengoko lujikeleza" luyenza iqine ngakumbi kunezixhobo ze-BT kumatshini onesantya esiphezulu.
2. Ukuchaneka kokubeka indawo okuphindwa kakhulu ngokugqithisileyo:
Umgaqo:Ubuso besiphelo se-flange somphathi wesixhobo se-HSK sinamathele ngokusondeleyo kwisiphelo sobuso be-spindle. Oku akuboneleli nje nge-axial positioning kodwa ikwanyusa kakhulu ukuxhathisa kweradial torsional. Oku "kunyanzeliswa kabini" kuphelisa ukungaqiniseki okubangelwa yi-conical surface fit gap kumphathi wesixhobo se-BT.
Iziphumo:Emva kokutshintsha kwesixhobo ngasinye, ukuphuma kwesixhobo (i-jitter) kuncinci kakhulu kwaye kuzinzile, okubalulekileyo ekufezekiseni umphezulu ophezulu, ukuqinisekisa ukuchaneka komda, kunye nokwandisa ubomi besixhobo.
3. Ukuchaneka okugqwesileyo kwejometri kunye nokungcangcazela okuphantsi:
Ngenxa yoyilo olulingeneyo lwendalo kunye nenkqubo yokwenziwa echanekileyo, umnini wesixhobo se-HSK ngokwendalo unomsebenzi ogqwesileyo oguqukayo. Emva kokulungiswa ngobuchule obuguquguqukayo (ukuya kuthi ga kwi-G2.5 okanye kumanqanaba aphezulu), inokuhlangabezana ngokugqibeleleyo neemfuno zokusila ngesantya esiphezulu, ukunciphisa ukungcangcazela ngowona mgangatho mkhulu, ngaloo ndlela kuzuzwa iziphumo ezikumgangatho ophakamileyo zesipili esifana nomphezulu.
4. Ixesha elifutshane lokutshintsha isixhobo kunye nokusebenza okuphezulu:
I-1: 10 idizayini emfutshane ye-taper ye-HSK ithetha ukuba umgama wokuhamba wesixhobo sokuphatha kwi-spindle hole mfutshane, okukhokelela ekusebenzeni ngokukhawuleza kokutshintsha isixhobo. Kufanelekile ngokukodwa ukucubungula ii-workpieces eziyinkimbinkimbi kunye nenani elikhulu lezixhobo kunye nokuguqulwa kwesixhobo rhoqo, ukunciphisa ngokufanelekileyo ixesha elincedisayo kunye nokuphucula ukusebenza kakuhle kwezixhobo.
5. Ukubhoboza okukhulu (kwimizekelo efana ne-HSK-E, F, njl.):
Eminye imifuziselo ye-HSK (efana ne-HSK-E63) inomngxuma omngxunya omkhulu ngokwentelekiso, onokuthi uyilwe njengejelo lokupholisa langaphakathi. Oku kuvumela ukupholisa koxinzelelo oluphezulu ukuba kutshizwe ngokuthe ngqo kwindawo yangaphakathi yesibambo sesixhobo kungqameko lokusika, kuphucula kakhulu ukusebenza kakuhle kunye nesakhono sokuqhawula itshiphu yokusetyenzwa kombhobho onzulu kunye nokulungiswa kwezinto ezinzima (ezifana ne-titanium alloys).
III. Iimeko zeSicelo soMphathi weSixhobo se-HSK
Isiphathi sesixhobo se-HSK asiyonjongo zonke, kodwa iingenelo zayo azinakuthathelwa indawo kule meko ilandelayo:
I-high-speed machining (HSC) kunye ne-ultra-high-speed machining (HSM).
I-five-axis precision machining ye-alloy eqinile / i-mold yentsimbi eqinile.
Iziko eliphezulu lokujika kunye nokusila elidityanisiweyo lokulungisa.
Intsimi ye-aerospace (ukucubungula i-aluminium alloys, izinto ezidibeneyo, i-titanium alloys, njl.).
Izixhobo zonyango kunye nokuveliswa kwamalungu achanekileyo.
IV. Isishwankathelo
Iinzuzo zeUmphathi wesixhobo se-HSKInokushwankathelwa ngolu hlobo lulandelayo: Ngoyilo oluyilayo lwe "cone emfutshane engenanto + isiphelo soqhagamshelwano olubini", isombulula ngokusisiseko iingxaki ezingundoqo zabaphathi bezixhobo zemveli, ezinjengokuncitshiswa kobulukhuni kunye nokuchaneka phantsi kweemeko zokusebenza ezinesantya esiphezulu. Inika uzinzo oluguquguqukayo olungenakulinganiswa, ukuphindaphinda ukuchaneka kunye nokusebenza kwesantya esiphezulu, kwaye lukhetho olungenakuphepheka kumashishini okuvelisa anamhlanje aphezulu aqhuba ukusebenza kakuhle, umgangatho kunye nokuthembeka.
