Iyiphi indlela yokwamukela isethi enhle yesikhunta okudingeka ihlangabezane nayo? Ingabe isikhunta sakho sihle?

Namuhla, ngifuna ukukuchazela indlela yokwamukela imikhiqizo yesikhunta. Ngokuyinhloko sihlaziya ukubukeka, ubukhulu kanye nempahla yesikhunta. Ake sibheke.

1. Ukubukeka kwesikhunta

1. Amaphutha ebusweni

Ukukhubazeka akuvunyelwe ebusweni besikhunta: ukungabi nalutho, ukuvutha, phezulu okumhlophe, imigqa emhlophe, iziqongo, ama-blistering, ukugcoba (noma ukuqhekeka noma ukuphuka), izimpawu zokubhaka, imibimbi, njll.

2. Izimpawu zokushisela

Ngokuvamile, ubude bezimpawu zokushisela ezimbotsheni eziyindilinga abukho ngaphezu kuka-5mm, kanti ubude bezimpawu zokushisela zokubhoboza okumise okukhethekile bungaphansi kuka-15mm, futhi amandla amamaki okushisela kufanele aphumelele ukuhlolwa kokuphepha okusebenzayo.

3. Nciphisa

Akukho ukuncipha okuvunyelwe ezindaweni ezisobala zokubukeka, futhi ukuncipha kancane kuvunyelwe ezindaweni ezingabonakali (akukho mazinyo angazwakala).

4. Ukucaba

Ngokuvamile, ukungalingani kwendiza yemikhiqizo emincane kungaphansi kuka-0.3mm. Uma kunezidingo zomhlangano, izidingo zomhlangano kufanele ziqinisekiswe.

2. Usayizi wesikhunta

1. Ukunemba

Umumo wejiyomethri nokunemba kobukhulu bomkhiqizo wesikhunta kufanele kuhambisane nezidingo zemidwebo esemthethweni nesemthethweni yokuvula isikhunta (noma amafayela e-3D). Ngaphezu kwalokho, ububanzi bokubekezelelana kwesikhunta kufanele buhambisane nezimiso ezifanele. Isibonelo, ukubekezelela usayizi we-shaft ukubekezelelana okungalungile, futhi ukubekezelelana kobukhulu bomgodi ukubekezelelana okuhle. Uma amakhasimende enezidingo ezikhethekile, abakhiqizi besikhunta bangakwazi nokwenza ngokwezifiso ukukhiqizwa ngokwezimo zangempela.

2. Ukujiya kodonga lwesikhunta

Ngokuvamile, ukushuba kodonga lwesikhunta kuhlukaniswe ngezinhlobo ezimbili: ukujiya kodonga okumaphakathi kanye nogqinsi olungeyona isilinganiso sodonga. Ubukhulu bodonga obungeyona isilinganiso kufanele buhambisane nezidingo zokudweba, futhi ngokusho kwezici zesikhunta, ukubekezelelana kwayo kufanele kube -0.1mm.

3. Iziqu zokufanisa

Igobolondo elingaphezulu negobolondo elingaphansi lesikhunta kufanele kufane kahle, futhi ukuchezuka kwawo akumele kube kukhulu kuno-0.1mm. Ngaphezu kwalokho, izimbobo, ama-shafts, nezindawo ezingaphezulu zemikhiqizo yesikhunta kufanele zihlangabezane nezikhala ezifanayo kanye nezidingo zokusetshenziswa, futhi akukho ukuklwejwa okwenzekayo.

4. Ipuleti legama

Umbhalo oseqenjini legama lesikhunta kufanele ucace, uhlelwe kahle, futhi uphelele ngokuqukethwe; i-nameplate kufanele ilungiswe ngokuthembekile futhi kungabi lula ukuwa.

5. Ukupholisa umbhobho wamanzi

Izinto ezisetshenziswayo zombhobho wamanzi wokupholisa isikhunta yipulasitiki (ikhasimende linezinye izidingo ngokuya ngezidingo), ezenziwa ngobuchwepheshe bokucubungula i-counterbore. Ububanzi be-counterbore ngokuvamile bungu-25mm, 30mm no-35mm, futhi isiqondiso se-chamfering yembobo siyahambisana. Ukwengeza, indawo yokufaka i-nozzle yamanzi okupholisa kufanele ihambisane nezidingo ezifanele futhi akufanele iphume ebusweni besisekelo sesikhunta, futhi izimpawu zokungena nokuphuma kufanele zimakwe.

6. Imbobo yokukhipha nokubukeka

Usayizi wembobo yokukhipha kanye nobukhulu bokubukeka kwesikhunta kufanele kuhambisane nezidingo zomshini wokubumba umjovo oshiwo. Ngaphandle kwesikhunta esincane, isikhungo esisodwa kuphela esingakwazi ukusetshenziselwa ukukhishwa.

3. Izinto zesikhunta nobulukhuni

1. I-Mold base material

Isisekelo sesikhunta kufanele sibe isisekelo sesikhunta esijwayelekile esihlangabezana nemithethonqubo, futhi impahla yaso kufanele ibe nokuguquguquka okuthile kwemvelo.

2. Ukusebenza

Ama-mold cores, izinto ezifakwayo ezinyakazayo nezingaguquki, izinto ezifakwayo ezinyakazayo, ama-diverter cones, izinduku zokusunduza, imikhono yesango nezinye izingxenye zinokuzinza okuhle nokumelana nokugqwala, futhi izakhiwo zazo ezibonakalayo ziphakeme kune-40Cr.

3. Ubulukhuni

Ukuqina kwezingxenye ezibunjiwe akumele kube ngaphansi kuka-50HRC, noma ubulukhuni bokwelashwa kokuqina kwendawo kufanele bube phezulu kuno-600HV.

Okungenhla kumayelana nezindinganiso zokwamukela isikhunta. Ngethemba ukuthi kuzoba usizo kuwo wonke umuntu.
