Uthini umgaqo wokusebenza koMashini oMbindi oPhetheyo oluPhezulu

       Icandelo elingundoqo lomsebenzi weOomatshini ababini abaPhezulu abaqengqelekayoyiperi yerola ezihambelanayo ezicwangciswe ngokuthe nkqo. Ngokuthembela kwi-gap phakathi kwee-roller ezimbini, ukunyanzeliswa kwe-rolling kusetyenziswe kumaphepha esinyithi, ama-strips, kunye neebhilidi, okubangela ukuguqulwa kweplastiki yezinto eziphathekayo, ukunciphisa ubukhulu kunye nobude, kunye nokuphumeza ukucolwa kunye nokubunjwa. Yahlulahlulwe yaba yinto enokubuyiswa kwaye ayinakuguqulwa; I-cold rolling kunye ne-hot rolling i-double roll mills inesakhiwo esilula kwaye iqhele ukusetyenziselwa ukuqengqeleka kwamaqhekeza amancinci, iifoyile, iintsimbi ezingenayo i-ferrous, kunye neebhilidi zensimbi.

Inkcazo epheleleyo yomgaqo wokusebenza

1.Roller gap setting

      Lungisa isithuba phakathi kweerola eziphezulu nezisezantsi ngokusebenzisa indlela yokucinezela (ihydraulic/screw pressing) ukuseta ubukhulu bokuqengqeleka ekujoliswe kuko; I-rolling Mill iqhutywa yi-motor engundoqo kunye ne-reducer, kwaye ijikeleza ngesantya esingaguqukiyo kwicala elichaseneyo: i-rolling mill ephezulu ijikeleza ezantsi, kwaye i-rolling mill esezantsi ijikeleza phezulu.

2.Ziluma kwibillet

      I-billet yondliwa kwicala lokungena phakathi kwee-rolling mill ezimbini. I-friction yenziwa phakathi kwendawo ejikelezayo ye-roller kunye ne-billet, edonsa i-workpiece kwi-gap ye-roller. Le nkqubo ibizwa ngokuba kukuluma.

3.Plastiki deformation (rolling core)

      I-billet ingena kwi-gap phakathi kwee-roller kwaye ixhomekeke kwisiphumo sokucudisa ii-roller ezimbini, ezibangela ukuguqulwa kweplastiki ngaphakathi kwesinyithi:

      Ukunciphisa ukutyeba (uxinzelelo)

      Isalathiso sobude siyandiswa kwaye sandiswa

      Ukwandiswa kancinci kobubanzi

      Umthamo wesinyithi uhlala ungatshintshi, kwaye izinto ezinobunzima obuncitshisiweyo ziguqulwa zibe yizandiso zobude.

      Ngaphakathi kwe-gap phakathi kwee-rollers, kukho i-sliding ehambelanayo phakathi kwezinto eziphathekayo kunye ne-rollers, kunye nesantya se-billet kwicala lokungena liphantsi kunomgca we-roller; Kwicala lokuphuma, isantya sokuhamba siphezulu kunesantya esiphezulu se-rolling mill, kwaye kukho indawo engathathi hlangothi.

4.Imveliso eqengqelekayo

      Emva kokucinezelwa nge-gap ye-roll, isiqwenga esisotyiweyo sithunyelwa ngaphandle kwecala lokuphuma kwi-rolling mill ukufumana iphepha / i-strip kunye nobukhulu obuncitshisiweyo.

      I-double roll rolling mill engenakubuyiselwa: Izinto zidlula kwicala elinye ukugqibezela inkqubo yokuqengqeleka;

      Ukuguqulwa kwe-double roll rolling mill: I-rolling mill inokuguqulwa, kwaye iqhekeza eliqengqelekayo lidlula ngokuphindaphindiweyo kwi-rolls emva naphambili, ngokuthe ngcembe liyancipha, lilungele ukulungiswa okukhulu kokunciphisa.

5.Inkqubo yokuncedisana nentsebenziswano

      Ukupholisa i-roller: Inkqubo yokuqengqeleka ivelisa ubushushu obukhulu be-deformation, kwaye indawo yokupholisa ifafazwe ukulawula ubushushu bee-roller;

      Indlela yoxinzelelo: Fakela iikhoyila zangaphambili nezingasemva ngexesha lokuqengqeleka kwemigca ukuseka ukuxinezeleka nokuqinisekisa ukuba mcaba kobume bepleyiti;

      Inkqubo yokucinezela: Ukulungiswa kwexesha langempela le-gap ye-roller ukulawula ukuchaneka kobunzima bemveliso egqityiweyo;

      Inkqubo yokuthanjiswa: Ukuthanjiswa kwe-oyile eqengqelekayo kunciphisa ukunxiba kwe-roll kunye nokuphucula umgangatho womphezulu.

Iimpawu eziphambili

      Ulwakhiwo olulula, iinkqubo zokuqengqeleka ezimbalwa, kunye notyalo-mali lwezixhobo eziphantsi;

      Ilungele ukuqengqeleka okushushu kunye nokuqengqeleka okubandayo; Iyakwazi ukuqengqeleka ubhedu, ialuminiyam, intsimbi engatyiwayo, intsimbi yekhabhoni, njl.
