Umehluko phakathi kwe-sandblasting ne-shot peening

Ukuqhunyiswa kwesihlabathi umoya ocindezelwe njengamandla okufafaza isihlabathi noma okokusebenza kokudubula ebusweni bento, ukuze kutholakale imvume kanye nokubangwadla okuthile.Ukudubula isibhamu kuyindlela yamandla aphakathi nendawo akhiqizwa lapho okokusebenza kokudubula kuzungeziswa ngesivinini esikhulu, okuthinta ingaphezulu lempahla ukuze kutholakale imvume kanye nokuba roughness okuthile.

I-shot peening kuyindlela yokukhipha ukugqwala kwensimbi ngokusebenzisa umoya ocindezelweyo noma amandla omshini we-centrifugal njengamandla kanye nokungqubuzana.
I-shot peening isetshenziselwa ukususa ubukhulu obungekho ngaphansi kuka-2mm noma akudingi ukugcina usayizi onembile kanye nephrofayili yesistimu yensimbi ephakathi nendawo enkulu.
Isikhumba se-oksijini, ukugqwala, isihlabathi esibumbayo nefilimu kapende endala ezingxenyeni zokusanhlamvu nezakhayo.Umthelela wokuchama ekwelapheni okungaphezulu uyabonakala.Kodwa i-workpiece enokungcoliswa kwamafutha, ukuchama okudutshulwa, ukuchama kwesibhamu akukwazi ukususa ngokuphelele ukungcoliswa kwamafutha.

I-sandblasting nayo iyindlela yokuhlanza ngomshini, kodwa ukuqhunyiswa kwesihlabathi akuqhumi, ukuqhunyiswa kwesihlabathi kuyisihlabathi esifana nesihlabathi se-quartz, ukuqhuma kwesibhamu kusetshenziswa namapellets ensimbi.Phakathi kwezindlela zokwelapha ezikhona, umphumela omuhle kakhulu wokuhlanza i-sandblasting.Ukuqhunyiswa kwesihlabathi kulungele ukuhlanza indawo yokusebenza enezidingo eziphezulu.Embonini yokulungisa nokwakha umkhumbi, ngokuvamile, ukudubula ukudubula (isibhamu esincane sensimbi) kusetshenziswa e-pretreatment ye-steel plate (ukususwa kokugqwala ngaphambi kokugqoka);Ukuqhunyiswa kwesihlabathi (ukulungisa, imboni yokwakha umkhumbi isetshenziswa esihlabathini samaminerali) kusetshenziswa ekubunjweni komkhumbi noma isigaba, indima iwukukhipha upende omdala nokugqwala epuleti lensimbi, bese upende kabusha.Embonini yokulungisa nokwakhiwa kwemikhumbi, umsebenzi oyinhloko wokudubula nokuqhunyiswa kwesihlabathi ukukhulisa ukunamathela komdwebo wepuleti lensimbi.
