Amathuluzi nemishini esetshenziselwa ukuzokwakhiwa kwamahhala ilula, ibiza imali yendawo yonke nephansi. Qhathanisa nokuphonsa kungenalutho,khululekile ukuthethelelaIkhipha i-shrinkage cavity, i-shrinkate poporia, epurate nezinye iziphambeko, ukuze kungenalutho kunezakhiwo eziphakeme zemishini.Ukuthethelelwazilula ngesimo futhi zivumelana nezimo ekusebenzeni. Ngakho-ke, kubaluleke kakhulu ekwenziweni kwemishini esindayo nezingxenye ezibalulekile.
Inkambu yesicelo
Ukuthethelelwa kwamahhalaalawulwa ngokusebenza ngesandla kwesimo nosayizi weukuthethelelwa, kanjaloUkucacisa UkunembaIphansi, ukucubungula imali kukhulu, ukuqina kwabasebenzi kukhulu, ukukhiqiza akuphezulu, ngakho-ke kusetshenziswa ikakhulukazi ekukhiqizeni okukodwa, okuncane kwe-batch.
1) usayizi we-billet nosayizi ophakathi kumele bavumelane namaphoyinti okusebenza kwenqubo ngayinye, efana nesilinganiso sobubanzi (h / d) wezinto ezibonakalayo ngaphambi kokucasuka ngu-2-2.5, kanye nedatha ebonakalayo yenguquko yesigaba lapho udweba ngaphandle.
2) Kuyadingeka ukulinganisa ushintsho ngosayizi ongenalutho kuizinqubo ezokwakha,Isibonelo, ukuphakama okungenalutho kuncishisiwe lapho kubhoboza, imvamisa izikhathi eziyi-1.1 zokuphakama okubandayo; Lapho shaft core raming ukuphakama kuyanda.
3) I-Indentation Yesigaba, kufanele iqinisekise ukuthi ingxenye ngayinye yalowo obizayo inevolumu eyanele, efana nesinyathelo SHAFT, CRANKSHATT NOMA I-TRE BOSS BOSTET, yenza umsebenzi omuhle wokusatshalaliswa kwengxenye ngayinye.
4) NiniukuthethelelaNgemililo eminingi, ukunakwa kufanele kukhokhwe kumathuba wokushisa umlilo ngamunye phakathi. Umaukuthethelelwazidonswa isikhathi eside kakhulu ekuqaleni, usayizi womlilo akwanele ukufaka lokhu okukhokhiswa isikhathi eside ngesikhathi sokushisa kwesibili. Ukuze uqinisekise usayizi kanye nekhwalithi yokwenziwa, ukunakwa okukhethekile kufanele kukhokhelwe ekuguqukeni komlilo ngemuva kwe-z nokulawulwa kokushisa kokuqala nokugcina kwayo ngemuva kukaZ.
5) Kuyadingeka ukuqinisekisa ukuthi kunemvume eyanele yokunciphisa isibonelelo ngemuva kokuqeda ngemuva kwe-z, futhi ukunakwa kufanele kukhokhwe ku:
.
(2) Ukwakha isikhathi esideUkukhokhiswa Shaft(njenge-crankshaft, njll.) FuthiukuthethelelwaNgama-concave amabhulokhi, ngoba usayizi wobude babo awunakuphatheka kabi, kufanele kulinganiswe ukuthi ubukhulu bendlela yobude buzonwetshwa kancane ekugqokeni futhi kuholele ekubekezeleni.

Kwakha.
6) Lapho ukhetha amathuluzi, izingane kufanele zisebenzise amathuluzi ajwayelekile. Lapho i-batch yokukhiqiza ikhulu, amathuluzi akhethekile noma isikhunta sopele angenziwa ukuthuthukisa ikhwalithi nokukhishwa komoya.
7) Ngokusho kobukhulu nekhwalithi ye-Blank, khetha imishini ekhona endaweni yokusebenzela.
