Zitsulo zachitsulo zimakhala paliponse, nthawi zonse

Pofuna kupewa dzimbiri zachitsulo, njira yodziwika kwambiri ndiyo kugwiritsa ntchito zokutira kuti ziteteze pamwamba pazitsulo zazitsulo.Pamwamba ayenera kutsukidwa pamaso ❖ kuyanika chitetezo.Mazana azinthu ndi mafakitale kuphatikiza zombo, akasinja osungira, milatho, zida zachitsulo, malo opangira magetsi, magalimoto, ma locomotives, zida zankhondo, zida zam'mlengalenga, ndi zina zotere ziyenera kuchitidwa pamwamba musanakutike.Metal abrasive ndiye njira yabwino kwambiri yoyeretsera.

Metallic abrasives

Nthawi zambiri, zilipokuwombera zitsulo (kuwombera kwachitsulo cha carbon highndilow carbon steel shot), zitsulo grit, kuwombera chitsulo, grit grit,chitsulo chosapanga dzimbiri chodula waya / chowombera chokhazikika, grit zitsulo zosapanga dzimbiri,zitsulo odulidwa waya, kukhala ndi grit yachitsulo, etc. High-performance metal abrasives sizovuta kuthyola, fumbi lochepa, kugwiritsira ntchito pang'ono, kuyeretsa kwakukulu, ndi ntchito yabwino yazinthu zonse.Itha kuchepetsa kwambiri kuchuluka kwa ogwiritsa ntchito kumapeto, potero kuchepetsa ndalama komanso kuchepetsa kutulutsa mpweya.

Ndiye funso ndilakuti, momwe mungasankhire ma abrasives achitsulo apamwamba kwambiri?

Kuonetsetsa kuti zotsatira za chithandizo chapamwamba zimakhala zogwirizana, zizindikiro ziwiri zazikulu zazitsulo zazitsulo: kuyeretsa bwino ndi kugwiritsa ntchito.

Kusamvetsetsana kangapo pakusankha kuwombera zitsulo:

Kodi chozungulira chitsulo chowumbidwa ndi chabwino?

Kodi kukula kwa tinthu ting'onoting'ono kofananako, kuli bwinoko?

Kuwala kowoneka bwino, kumakhala bwinoko?

Kodi chozungulira chitsulo chowumbidwa ndi chabwino?

Yankho: Ayi.

Popanga ndi kukonza zowombera zitsulo, chitsulo chosungunulacho chimakhazikika kuchokera kumadzi kupita ku cholimba, ndipo chimachepa panthawi yozizira.Kutsika uku kumachitika mwaulere, ndipo palibe chokwera ngati kuthira zotayira kuti ziphatikizidwe pang'ono ndi chitsulo chosungunula pomwe voliyumu ikatsika imachepetsedwa, kotero kuti tinthu tating'onoting'ono tomwe timakhala titalowa timawoneka.Tinthu tating'onoting'ono tamtunduwu tachepa mokwanira, ndipo mawonekedwe ake si ozungulira koma mawonekedwe ake ndi owundana.Komabe, ngati chitsulo chowombera chomwe sichinagwirizane kwathunthu, kapangidwe kake kamakhala kocheperako, pali zolakwika zamkati monga shrinkage porosity ndi shrinkage cavities.

Kuponyera mphamvu E=1/2mv2, ngati kapangidwe kake ndi kowuma, voliyumu yomweyi, kachulukidwe wamkulu M ndi, mphamvu yakukulirakulira, komanso yosavuta kusweka.Mwanjira iyi, sizolondola: chitsulo chozungulira chimawombera bwino.

Kodi kukula kwa njere kwachitsulo chowombera yunifolomu, kuli bwinoko?

Yankho: Ayi.

M'munda wa kuyeretsa, pamwamba pa workpiece kutsukidwa kapena kupopera mbewu mankhwalawa kupanga maenje pa kutsukidwa pamwamba.Pokhapokha ngati maenje ndi maenje alumikizana mokwanira, pamwamba pake amatha kutsukidwa bwino.

The kwambiri yunifolomu kukula kwa tinthu kuwombera zitsulo ndi, motalika zimatenga kufika anagwirizana mokwanira maenje.For zitsulo akatemera ndi ena tinthu kukula kusakaniza chiŵerengero, akatemera lalikulu zitsulo makamaka ntchito kuyeretsa, ndi akatemera ang'onoang'ono zitsulo. adzayeretsa interspace pakati pa chigawo chochitidwa ndi kuwombera kwakukulu kwachitsulo

Kuwala kowoneka bwino, kumakhala bwinoko?

Yankho: Ayi.

Panopa pali mitundu iwiri yakuwombera kwachitsulo cha carbon high: single quenching zitsulo kuwombera ndi pawiri quenching zitsulo kuwombera.Ndizovuta kusiyanitsa ndi kapangidwe, kuuma, ndi kapangidwe ka metallographic.Komabe, kuwombera kawiri chitsulo chozimitsidwa kumakhala ndi mbewu zabwino komanso kutopa kwakukulu, Mbewu zachitsulo chozimitsira chitsulo chimodzi ndizovuta komanso moyo wotopa ndi wochepa. pamwamba ndi yoonda, imawoneka yowala kwambiri;pamene chitsulo chinawomberedwa pambuyo pa chithandizo chachiwiri chozimitsa, filimu ya Fe3O4 pamtunda imakhala yowonjezereka, sichiwonetsa kuwala, ndipo sichiwoneka chonyezimira.Choncho kuwala pamwamba sikutanthauza mankhwala bwino, koma ngati ndi pawiri kuzimitsa zitsulo kuwombera kapena ayi ndi nkhani yofunika kwambiri.
