Ukucima ukupholisa isiganeko sokuqhekeka kwe ukucima rhoqo

Ukucima kunye nokupholisa ukukhwabanisa kubhekisela kwinto yokuba iintanda zenziwe kwi-workpiece xa uxinzelelo ngexesha lokucima kunye nokupholisa kudlula amandla okuphuka kwezinto kule bushushu. Ngokuqhelekileyo ngaphantsi kwe-200 ° C, ngenxa yokuguqulwa kwe-martensitic, uxinzelelo olukhulu lwenguqu luyenziwa, kwaye ngelo xesha, iplastiki yensimbi ihlwempuzekileyo kule bushushu, kwaye i-cracks iyakwazi ukwenzeka. Ukucima ukuqhekeka kunokwenzeka ngexesha lokupholisa, xa inxalenye ikhutshwe nje phakathi, okanye xa igcinwe ixesha elithile.

Iindidi eziphambili zokucima iintanda zezi: ukuqhekeka kwe-longitudinal okubangelwa ukunyanzeliswa kwe-tangential residual enkulu kunolwalathiso lwe-longitudinal ye-slender cylindrical parts emva kokucima; Uxinzelelo lukhulu kakhulu kunoqhekeko olunqamlezayo olubangelwa luxinzelelo lwe-tangential; iinxalenye ze-tubular okanye iinxalenye ezinemingxuma zihlala zenza iintanda kudonga lwangaphakathi lomngxuma ngenxa yokwahlukana kwesantya sokupholisa phakathi kodonga lwangaphakathi lomngxuma kunye nezinye iindawo.
