Umsiki amazinyo
Ikhanda lokusika ngokuvamile liqukethe izingxenye ezine, kufaka phakathi amazinyo wokusika (ingxubevange), umsiki womzimba, iqabunga lentwasahlobo kanye ne-circlip, kuyilapho kungamazinyo ambalwa kuphela okusika, umzimba wokusika kanye nesiringi, njll. Ukugaya kudinga ukuthi amazinyo wokusika asike emhlabathini ekuqaleni . Ngakho-ke, amazinyo okusika kufanele abe nokumelana nokushaqeka okukhulu. Amazinyo wokusika ngokujwayelekile acwengeka ngophawuda we-Tungsten Cobalt alloy powder endaweni ye-vacuum, bese ushiselwa emzimbeni wokusika ngezici zamandla we-flexural 2400n / mm² kanye nobuningi obuphakathi kuka-14.5-14.9cm³, okuyi-high-density, high wear-resistance futhi ukumelana nokushaqeka okuqinile.
Umsiki umzimba uvame ukwenziwa ngezinto ezinokugqokwa ezingama-42Crmo futhi zicutshungulwe yiCold Extrusion Molding Machine. Ngamandla aphezulu okuguquguquka nokuqina kokugqoka okuphezulu, isetshenziselwa ukuxhasa nokuvikela amazinyo wokusika. Isiringi enokunwebeka okuphezulu ikhiyiwe enqenqemeni yekhanda lokusika, elicindezelwa yinsimbi egoqiwe engu-65Mo yokuqina okukhulu. Ingakhiya ngokuqinile ikhanda lomsiki isikhathi eside futhi iqiniseke ukuthi ikhanda lomsiki lingazungeza kalula esiteshini. Iqabunga lasentwasahlobo likhiyiwe kusiringi, elingavumela ukufakwa kwekhanda lokusika esiteshini kalula. Lokhu akukwazi ukuhambisa nje kuphela ukuhlangana kwekhanda lokusika, kepha futhi kuvikele isiteshi ngempumelelo futhi kusenze sibe ngaphansi komhuzuko ojwayelekile. Iqabunga lasentwasahlobo livame ukwenziwa ngezinto ezingamelana nokugqoka ngobuchwepheshe bezindaba ezibandayo. Ubulukhuni baso isiqinisekiso esibalulekile sokusetshenziswa okujwayelekile kwekhanda lokusika, kuyilapho ubunzima obucimayo obufanele bungeza impilo yomsebenzi wokusika. Ubulukhuni bomzimba wokusika ulawulwa phakathi kuka-44-48HRC futhi amazinyo okusika azungeze i-89HRA. Kusetshenziswa ubuchwepheshe bokushisela obusebenzisa imvamisa ephezulu noma obenziwe ngeNickel ukuze kuqinisekiswe ukuthi awehli amazinyo okusika ingxubevange.
Isimiso sokusebenza se-Milling Cutter Head
Inhloko yokusika imishini ibalulekile ekwakhiweni kwemigwaqo. Ikhanda lokusika lisebenza njengezandla zalo zangakwesobunxele nangakwesokudla, eziphethe ingxenye ebaluleke kakhulu: Indawo yokugaya. Ukuze uqedele ukusika okuyinhloko, ikhanda lokusika lenziwe ngezinhlayiya ezinkulu ze-Tungsten carbide alloy futhi lixhunywe ngensimbi ye-Cobalt ethambile, ubunzima bayo obufinyelela ku-1400HV. Ngisho nangaphansi kokushisa okuphezulu kanye ne-velocity ephezulu, iveza ukumelana okuhle kakhulu kokuphinda futhi igqoke ukumelana. Umphetho wokusika usesimweni sesigaxa. Ububanzi obuncane obuphezulu bungehlisa ukusebenza kwesigaxa nokumelana lapho kusikwa ngokuqhubekayo emhlabathini. Ububanzi obukhulu baphansi obuphezulu buhlinzeka ngokuvikelwa kwesandla soshodi. Umngcele wokusika uxhunyaniswe kakhulu ne-shank ngokusebenzisa insimbi ekhethekile yensimbi yensimbi. Ngaphandle komphetho wokusika, ibuye ibambe i-shank nomzuzu wokugoba we-6 ton-force kusiqondisi se-45 degree.
Izingxenye ezingenhla nezingezansi zokhiye wommese wokhiye zinezinto ezihlukile zomshini. Ingxenye engenhla inokushayisana nomhlabathi futhi isusa imfucuza, edinga ubulukhuni obuphakeme kakhulu. Isigxobo esivela engxenyeni engezansi sifaka esiteshini sommese ukwenza ukukhuhla. Ukuqina okuhle kuyivumela ukuthi ingene esitelekeni sangaphakathi. Ngakho-ke, isibambo sommese kufanele sibe nokusebenza okumbaxambili: ukulwa okuqinile nokungqubuzana okuqinile. Kukhona isiqu maphakathi, lapho isiqeshana sesichibi singadonsa umphetho wommese ngaphandle kwesiteshi. Ngaphandle kwayo, eminye imimese ingahle yeluleke ngemuva ngokushaqeka ngenkemba. Izimbambo ezimbalwa zommese ezintsha zinemifantu ekhanda, engaqinisa ukujikeleza futhi ivimbele ukuhuzuka okungalingani ekuxabaneni nomhlabathi.
