Umatshini wokucheba osetyenziselwa ukucheba okunqamlezayo kwesitokhwe esiqengqelekayo esiqengqelekayo ubizwa ngokubaukucheba okubhabhayo.Ngophuhliso lweentsimbi eziqhubekayo zentsimbi yokusila, icandelo lentsimbi yokusila kunye ne-billet rolling mills kunye nokuphuculwa kwemveliso yokucheba ezindizayo, ukusetyenziswa kweeshears eziphaphazelayo kuya kuba kuninzi ngakumbi.Kukho iintlobo ezininzi zeeshears ezibhabhayo, ezisetyenziswa ngokubanzi: izikere eziphaphazelayo zediskhi, igubu eliphindwe kabini lokucheba, i-crank rotary kunye ne-pendulum flying shears.
1. Izikere eziphaphazelayo zediskhi
Izikere ezibhabhayo ezinjalo zidla ngokusetyenziswa kwiindawo zocweyo ezincinci zokungqusha.Ifakwe phambi kwebhedi yokupholisa ngokukhawuleza ukusika isitokisi esiqhekezayo ukwenzela ukuba isitokhwe esingena kwibhedi yokupholisa singabi side kakhulu;okanye ifakwe phambi kokugqiba i-rolling mill ukusika i-rolling piece ukuze kuqinisekiswe inkqubo yokugqiba i-rolling rolling.uhambe kakuhle.I-flying shear iqulethwe ngamabini amabini okanye ngaphezulu e-disc-shaped blades, kwaye i-axis ye-disc ilingana nesantya sentsimbi.Xa i-shear ikwindawo yokuqala, intsimbi iqhubela phambili ecaleni kwe-inlet duct ukuya ngasekhohlo kwe-shear.Xa isinyithi sisebenza kwi-flag yeflegi okanye isikhokelo sokukhanya, isikhokelo sokungena kunye nentsimbi ijikisiwe ngasekunene, kwaye intsimbi ingena phakathi kweediski ezimbini zokucheba.Emva kokuba i-blade ephantsi iyancipha, i-conduit ibuyisela intsimbi kwindawo yayo yangaphambili yesandla sasekhohlo, emva koko i-blade ephantsi iphakama kwakhona.Ukungalungi kolu hlobo lwe-flying shear kukuba i-incision i-oblique, kodwa inempembelelo encinci kwi-rough cut phambi kwentloko yokusika okanye ibhedi yokupholisa.Ngenxa yokuba lo matshini wokucheba uthembekile ekusebenzeni, ulula kwisakhiwo, kwaye unesantya sokucheba esingaphezulu kwe-10m/s, sisetyenziswa ngokubanzi kwiiworkshops ezincinci zokusila.
2. Isikere esiphaphazelayo esinamagubu amabini
Igubu eliphindwe kabiniizikere eziphaphazelayozisetyenziswa kakhulu ekuchebeni intsimbi kunye neepleyiti zentsimbi xa zihamba.Umgaqo wokusebenza umi ngolu hlobo lulandelayo: Kwimigqomo emibini ejikelezayo, iiblade ezimbini zilungiswe ngeradially.I-stock rolling ehamba kunye netafile ye-roller inqunywe ngamacangci amabini adibanayo xa edlula phakathi kwee-roller ezimbini.Isantya se-peripheral ye-blade kufuneka sibe sikhulu kancinane kunesantya esishukumayo sesiqwenga esiqengqelekayo, kungenjalo isiqwenga esiqengqelekayo siya kugoba emnyango xa kuchetywa.Ukungalungi kolu hlobo lokucheba okubhabhayo kukuba icandelo aligudi xa kuchetywa iziqwenga ezishinyeneyo ezisongiweyo (impembelelo enkulu kakhulu ekuchebeni iziqwenga ezibhityileyo ezisongiweyo);xa usikwa iipleyiti zentsimbi ezibanzi, amandla okucheba makhulu.Ke ngoko, esi sichebi sibhabhayo sisetyenziselwa ukusika amacandelo amancinci kunye namaphepha esitokhwe esinesantya esiphezulu.
3. Izikere ezibhabhayo zeCrank rotary
Umtshini wayo wokucheba wenziwa yindlela yokudibanisa imivalo emine, kwaye iblade yokucheba ihamba ngendlela eqikelelwayo kwindawo yokucheba kwaye ixhomekeke kumphezulu wesiqwenga esiqengqelekayo.Ngoko ke, icandelo elisikiweyo leqhekeza eliqengqelekayo lithe ngqo.Indlela yokucheba ye-flying shear yenziwe ngumnini wesixhobo, umkhono we-eccentric kunye nentonga yokujingi.Isixhobo sokuphumla sikwimo ye-lever, enye isiphelo sayo sigxininiswe kwi-sleeve eccentric, kwaye esinye isiphelo sidibaniswe ngentonga ye-swing.I-swing fulcrum yentonga yokujingi ixhomekeke kwikholamu.Xa i-eccentric sleeve (i-crank) ijikeleza, umnini wesixhobo uyahamba ekuguquleleni, kwaye i-blade egxininiswe kwisibambi sesixhobo ingaba yi-perpendicular okanye malunga ne-perpendicular kwi-workpiece.Xa kuchetywa iipleyiti zentsimbi, i-oblique blade ingasetyenziselwa ukunciphisa amandla okucheba.Ukungalungi kwesi sichebi sibhabhayo kukuba isakhiwo sinzima, iimpawu zomthwalo oguqukayo wendlela yokucheba zihluphekile, kwaye isantya sokuhamba se-blade asikwazi ukukhawuleza.Ngokuqhelekileyo isetyenziselwa ukucheba iipleyiti zentsimbi ezishinyeneyo okanye iibhilithi.
4. Izikere ezibhabhayo zePendulum
Izikere ezibhabhayo ezinjalo maxa wambi zisetyenziswa koololiwe abanqumlayo kwiindibano zocweyo zokusila zentsimbi eziqhubekayo.I-blade yale shear endizayo nayo ihamba ngokuguqulela, kwaye umgangatho weplate yokusika ungcono.Umphathi wesixhobo esiphezulu ugxininiswe kwisakhelo sokuguqula.Isakhelo se-swing sixhaswa kwi-eccentricity ye-shaft engundoqo.Kukho izibini ezimbini ze-eccentrics kwi-shaft engundoqo, kwaye enye iperi ye-eccentrics idityaniswe kunye nesixhobo esisezantsi sokuphumla ngokusebenzisa intonga yokudibanisa, kwaye ukuphumla kwesixhobo esisezantsi kunokutyibilika kwi-chute yesakhelo sokujingi.Ekubeni izibini ezimbini zeendawo ezi-eccentric kwi-shaft engundoqo zihluke nge-180°, xa i-shaft engundoqo ijikeleza, ukuphumla kwesixhobo esiphezulu kuhla kunye nesakhelo, kwaye ukuphumla kwesixhobo esisezantsi kuyanyuka ukugqiba isenzo sokucheba.Nangona kunjalo, inokunciphisa isitokhwe esimileyo kuphela.Ukuze ukwazi ukusika isitokhwe esihambayo, kuyimfuneko ukwenza isakhelo sokujingi sikwazi ukujikeleza ngasemva naphambili.Inxalenye esezantsi yesakhelo sokujingi sidityaniswe ngokuxhomekeke kwintonga ye-eccentric, kwaye ivili le-eccentric lixhonywe kwi-axle yangasemva.I-axle yangasemva iqhagamshelwe kwi-shaft ephambili nge-pinions, ii-racks kunye nee-synchronizing discs.Xa i-shaft engundoqo ijikeleza, isakhelo sinokuhlanjululwa ngasemva naphambili kunye ne-shaft engundoqo njengeziko eliphakathi kwi-synchronizing disc, i-rack, i-pinion kunye ne-eccentric rod yokudibanisa kwi-axle yangasemva.Ngeli xesha, umbambi wesixhobo uyashukuma ekuguquleleni ukuqonda umsebenzi wokucheba we-pendulum flying shear.Indima yomatshini wokucheba kwi-rolling mill ayiyona indawo ephambili, kodwa idlala indima ebalulekileyo ekuchanekeni kunye nokuma kwemveliso egqityiweyo.Iindidi ezahlukeneyo zokugaya kufuneka zikhethe ukucheba okubhabha okuhambelanayo, ukwenzela ukuba umgca wemveliso wonke ufezekise injongo.ubungakanani kunye nokuchaneka.
