Inhloko ye-Extrusion ye-Aluminium Extresion
Inhloko ye-Extrusion iyimishini yokuqhekeka okubaluleke kakhulu esetshenziswa kwinqubo yokukhishwa kwe-aluminium (Fig 1). Izinga lomkhiqizo ocindezelwe kanye nokukhiqizwa okuphelele kwe-extred kuncike kukho.

Ukusebenza okuhle kwekhanda lokukhishwa kuncike ezintweni ezinjengokuthi:
Ukuqondanisa okuphelele kwe-extred
Ukusatshalaliswa kokushisa komgqomo we-Extresion
Izinga lokushisa nezinto ezibonakalayo ze-aluminium mallt
Ukuthambisa okufanele
Ukulungiswa okujwayelekile
Umsebenzi wekhanda lokukhishwa
Umsebenzi wekhanda le-Extresion ubonakala elula kakhulu ekuqaleni kokuqala. Le ngxenye ifana nokuqhubeka kwenduku yokukhishwa futhi yenzelwe ukucindezela i-aluminium alloy evuthayo futhi ethambile ngqo ngokusebenzisa okufayo. Ikhekhe le-Extrusion kumele lenze imisebenzi elandelayo:
Dlulisa ingcindezi ku-alloy emjikelezweni ngamunye wokukhishwa ngaphansi kwezimo eziphakeme zokushisa;
Sondezela ngokushesha ngaphansi kwengcindezi emkhawulweni onqunyelwe kusengaphambili (Umdwebo 4), kushiya kuphela isendlalelo esincanyana se-aluminium alloy esikhwameni sesitsha;
Kulula ukuhlukana nesikweletu ngemuva kokuqedwa kokukhishwa;
Ungabisi noma yiliphi igesi, engalimaza umkhono wesitsha noma ibhulokhi le-dummy uqobo;
Siza ukuxazulula izinkinga ezincane ngokuqondanisa kwabezindaba;
Ikwazi ukufakwa ngokushesha / kwehlelwe ngenduku yabezindaba.
Lokhu kumele kuqinisekwe ngokugxila okuhle kwe-extruder. Ukuphambuka ekuhambeni kwekhanda le-extrusion kusuka ku-axis extruder kuvame ukwamukelwa kalula ngokugqoka okungalingani, okubonakalayo kumasongo wekhekhe le-extrusion. Ngakho-ke, i-PRESS kufanele ihambisane ngokucophelela futhi njalo.

Insimbi yekhanda lokukhishwa
Inhloko ye-Extrusion iyingxenye yethuluzi le-Extrusion elibhekwe ekucindezelweni okuphezulu. Inhloko ye-Extrusion yenziwa ngethuluzi lokufa (isib. H13 Steel). Ngaphambi kokuqala kwabezindaba, inhloko ye-Extresion ifudunyezwa kumazinga okushisa okungenani angama-300 º. Lokhu kwandisa ukumelana kwensimbi ekucindezelekeni okushisayo futhi kuvimbela ukuqhekeka ngenxa yokushaqeka okushisayo.

Lokushisa le-billet, isitsha futhi sife
Imali ekhokhwa ngokweqile (ngenhla kwe-500ºC) izonciphisa ingcindezi yekhanda lokukhishwa ngesikhathi senqubo yokukhishwa. Lokhu kungaholela ekwandisweni okunganele kwekhanda lokukhishwa, okubangela ukuthi i-malet yensimbi ibekwe kwigebe phakathi kwekhanda lokukhishwa nesitsha. Lokhu kunganciphisa impilo yenkonzo ye-dummy block futhi kuholele ngisho nokuguqulwa okubalulekile kwepulasitiki kwensimbi yalo ngekhanda lokukhishwa. Izimo ezifanayo zingenzeka ngeziqukathi ezinezindawo ezihlukile zokushisa.
Ukunamathela kwekhanda lokukhishwa ku-billet kuyinkinga enkulu kakhulu. Lesi simo sivame kakhulu ngemichilo emide yokusebenza kanye nama-alloys athambile. Isixazululo sanamuhla sale nkinga ukufaka i-lubritant kususelwa kuBoron NITride kuze kube sekupheleni kokusebenza.
Ukugcinwa kwekhanda lokukhishwa
Inhloko ye-Extresion kumele ihlolwe nsuku zonke.
Ukunamathela kwe-aluminium okungenzeka kunqunywa ngokuhlolwa okubukwayo.
Bheka ukuhamba kwamahhala kwenduku nendandatho, kanye nokwethenjwa kokulungiswa kwazo zonke izikulufa.
Ikhekhe le-Extrusion kumele lisuswe kwabezindaba masonto onke futhi lihlanza i-die etching groove.
Ngesikhathi sokusebenza kwekhanda lokukhishwa, ukwanda ngokweqile kungenzeka. Kuyadingeka ukulawula lokhu kwanda okungafanele kube mkhulu kakhulu. Ukwanda okweqile kobubanzi be-washer yokucindezela kuzokunciphisa kakhulu impilo yayo yenkonzo.
