Ukuhlaziywa kwenqubo yokusebenzisa i-hand reamer imishini yokuqeda imvamisa ephezulu yokwelapha ukushisa

Izisetshenziswa zokucisha izandla zisebenzisa imishini yokucisha imvamisa ephezulu ekwelapheni ukushisa. Kunezici eziningi ezithinta umphumela wokwelapha ukushisa, njengenqubo yokwelashwa kokushisa nezinto zokusetshenziswa. Phakathi kwalezi zici, inqubo yokwelapha ukushisa inethonya elikhulu kakhulu. Ngakho-ke, kudingekile kakhulu ukukwazi kahle inqubo yokwelapha ukushisa kwe-reamer yesandla.

1. Izidingo zobuchwepheshe ze-hand remer:

Izinto ezisetshenziswa kakhulu ze-hand remer yinsimbi engu-9SiCr.

Ukuqina: 62-64HRC ye-φ3-8; 63-65HRC ye-φ8.

Ukubamba ubulukhuni: 30-45HRC.

Inani lokuhlanekezelwa kokugoba kwesivuseleli sesandla linqunywa ukuthi libe ngu-0.15-0.3mm ngokuya ngobubanzi nobude.

2. Inqubo yokwelapha ukushisa

Umzila wenqubo yokwelapha ukushisa uthi: ukushisa kuqala, ukufudumeza, ukupholisa, ukuqondisa, ukufudumeza, ukuhlanza, ukuhlola ubulukhuni, ukumnyama, nokuhlolwa kokubukeka. Inqubo yokushisa iqhutshwa kakhulu imishini yokucisha imvamisa ephezulu, phakathi kwayo izinga lokushisa elingaphambi kokushisa lingu-600-650 ° C, izinga lokushisa lokushisa liyi-850-870 ° C, futhi izinga lokushisa liyi-160 ° C.

I-reamer yesandla ingacinywa iyonke bese ivala shank. Ukushisa kwe-annealing kungu-600 ° C, bese kucinywa kusawoti we-nitrate ku-150-180 ° C ukuze kuphole ngaphezu kwama-30s.

3. Incazelo yenqubo

(1) Ukuze kuncishiswe ukugoba kwe-remer ngemva kokucisha, i-anneal yokunciphisa ukucindezeleka ingasetshenziswa ngaphambi kokucisha.

(2) Ukuze kuncishiswe ukuhlanekezela kwe-remer enobubanzi obungaphansi kwe-13mm, umkhawulo ophansi wokushisa okucisha ungathathwa. Ngamandla ehinge anobubanzi obungaphezu kuka-13mm, ukuze kuthuthukiswe ukuqina kwawo, izinga lokushisa eliphezulu lokucisha umkhawulo kanye nokupholisa uwoyela oshisayo kungasetshenziswa.
