Indlela evamile yokukhiqiza yezikhala ze-aluminium piston yindlela yokukhipha amandla adonsela phansi ensimbi. Ikakhulukazi, isikhunta samanje sensimbi sesiqalile ukucutshungulwa ngamathuluzi omshini we-CNC, angaqinisekisa ukunemba kosayizi ongenalutho, ukukhiqiza okuphezulu kanye nezindleko eziphansi. Ngomgodi we-piston oyinkimbinkimbi, umgogodla wensimbi ungahlukaniswa ube yizicucu ezintathu, ezinhlanu noma eziyisikhombisa ukuze zibunjwe, okuyinto eyinkimbinkimbi futhi engapheli. Le ndlela yokukhipha amandla adonsela phansi kwesinye isikhathi ikhiqiza amaphutha njengokuqhekeka okushisayo, izimbotshana, izimbobo, nokuxega kwepiston elingenalutho.

Ezinjinini eziqinisiwe, ama-piston e-aluminium alloy angasetshenziswa angasetshenziswa, anezinhlamvu ezicwengiwe, ukusabalalisa okuhle kwensimbi, amandla aphezulu, isakhiwo sensimbi esihle kanye nokuhamba kahle kwe-thermal. Ngakho-ke izinga lokushisa lepiston liphansi kunalelo lokusakazwa kwamandla adonsela phansi. I-piston inobude obuphezulu kanye nokuqina okuhle, okunenzuzo ekudambiseni ukugxilisa ingqondo. Kodwa-ke, ama-alloys e-aluminium-silicon e-hypereutectic aqukethe ngaphezu kuka-18% we-silicon awafanele ukufojwa ngenxa yokuqina kwawo, futhi ukufoja kuvame ukubangela ukucindezeleka okukhulu kwensalela ku-piston. Ngakho-ke, inqubo yokubumba, ikakhulukazi ukushisa kokugcina kokushisa nokushisa kokushisa kokushisa kufanele kube okufanelekile, futhi iningi lokuqhekeka kwe-piston ehlanganisiwe ngesikhathi sokusetshenziswa kubangelwa ukucindezeleka okusalayo. I-Forging inezidingo eziqinile ekubunjweni kwesakhiwo se-piston kanye nezindleko eziphezulu.

Inqubo ye-liquid die forging process yaqala ukusetshenziswa ekukhiqizeni ngeMpi Yezwe Yesibili, futhi iye yakhuthazwa futhi yasetshenziswa ngamazinga ahlukene emazweni ahlukahlukene emhlabeni jikelele. Ifinyelele intuthuko esheshayo kule minyaka eyishumi edlule. izwe lami laqala ukusebenzisa lolu hlelo ngo-1958 futhi linomlando weminyaka engama-40.

I-Liquid die forging iwukuba uthele inani elithile lensimbi ewuketshezi ibe isikhunta sensimbi, ucindezele nge-punch, ukuze insimbi ewuketshezi igcwalise umgodi ngesivinini esiphansi kakhulu kune-die casting, futhi icwebezele futhi iqine ngaphansi kwengcindezi ukuze ithole eliminyene. isakhiwo. Imikhiqizo engenawo umgodi wokuncipha, i-shrinkage porosity nezinye iziphambeko zokuphonsa. Le nqubo inazo zombili izici zokulingisa nokufoja.
