Ithuluzi lomshini wokuqeda intambo yensimbi yasentwasahlobo yemoto

Ngokuthuthuka komkhakha wezimoto wezwe lami, isidingo semakethe yezintambo zensimbi zentwasahlobo ezimisiwe, ikakhulukazi izintambo zensimbi ezisezingeni eliphakeme ezicinyiwe nezinciphile, zikhuphuke kakhulu. Esikhathini esedlule, bekuncike kakhulu ekungenisweni kwempahla ezweni, okudla imali eningi yangaphandle.

The imishini yokuqeda ukushisa iyinsimbi yokucima ijubane lamanzi nejubane eliphezulu engacindezela izintambo zensimbi yasentwasahlobo engu-6-12 mm ngaphandle kokuqhekeka kanye nenqubo yokuvala okuhambisanayo. Ijubane lokuhamba ngocingo liyi-8-40 m / min, ukuqina kobuso bensimbi yensimbi ngemuva kokucima i-HRC 62-64, ubunzima obukhulu be-HRC ngu-60-62, kanti usayizi wokusanhlamvu ungu-11-12. Ukucwengwa okusanhlamvu nokuvuselelwa kwe-martensite yizizathu eziyinhloko zokwenyuka okukhulu kwamandla kanye nepulasitiki lokushisa okufakwayo okucishiwe futhi okuthulisiwe. Usayizi wayo wokusanhlamvu amamaki ayi-11 kuye kwayi-14, kanti ukufudumeza kwesithando somlilo kungafinyelela kuphela kumabanga ayi-7 kuye kwayi-10.

Ukusetshenziswa kwemvamisa enkulu yomsindo nobuningi obuphakathi bokufudumeza kokungeniswa okuqhubekayo kwe-austenitization kanye nokupholisa i-jet yamanzi nokuqeda. Ngokuvamile kukholakala ukuthi lapho ingxenyenamba yesisindo sekhabhoni endukwini yocingo ingaphezu kuka-0.3%, kulula ukucishwa ukupholisa nokuqeda amanzi. Ngakho-ke, ukuphikisana okuyinhloko okudinga ukuxazululwa kwenqubo yokuqeda kuyenza lukhuni futhi kucime ukuqhekeka.

Emkhakheni wezimoto, izixazululo eziphelele zokucima nokushisa. Ithuthukise futhi yakhiqiza amathuluzi omshini wokucima umshini wokuqeda ukucima, amathuluzi womshini wokucima okuqonde ngqo mpo, amathuluzi womshini wokucima izicathulo, amathuluzi womshini wokucisha umshini wokucisha umshini, amathuluzi womshini wokucisha umshini weselula, amakholomu amathathu wekholomu yegobolondo yokuqothula / okokushisa, izinsimbi zensimbi / Izikhumulo zamasondo Ukufaka imishini yokuqeda / yokushisa, imoto ibhalansi shaft amathuluzi womshini wokucima iziteshi eziningi asetshenziswa kakhulu kubakhiqizi abaningi bezimoto.
