Mokhoa oa ho khetha sebōpi sa forging?

1. Khetho ea ho forging futhumatsang sebōpi ke ho ela hloko pele mocheso o futhumatsang le ho fumana thepa ea workpiece e futhumetseng. Mocheso oa mocheso oa mochine o futhumetseng oa lisebelisoa tse fapaneng o fapane, ‘me o tlameha ho finyella litlhoko tsa ho futhumatsa. Ka mohlala, mocheso o futhumatsang oa thepa ea tšepe ea alloy ke likhato tse 1200, mocheso o futhumatsang oa thepa ea aluminium ke likhato tse 450, ‘me mocheso oa mocheso oa lisebelisoa tsa koporo ke likhato tse 1000. Mocheso oa mocheso o lokela ho khethoa ho ea ka litlhoko tsa ts’ebetso.

2. Khetho ea ho forging libopi tsa ho futhumatsa e lokela ho ela hloko litekanyo tsa ka ntle tsa li-workpieces tse futhumetseng. Boima ba li-workpieces tse futhumetseng li ka khethoa ke litekanyo tsa ka ntle, e le ho fumana hore na mocheso o kenngoa ke li-workpieces tse futhumetseng ho ea mocheso oa tshebetso ho tseba feela matla a ho futhumatsa. Ha e le hantle, sebopeho le boholo ba workpiece e lokelang ho futhumatsoa ke mekoallo e meholo, e chitja, le lisebelisoa tse tiileng, ‘me ho lokela ho sebelisoa sebōpi se futhumatsang bar se nang le matla a phahameng a lekanyelitsoeng le maqhubu a tlaase; Sebōpi se futhumatsang maqhubu a phahameng.

3. Khetho ea ho forging sebōpi sa ho futhumatsa e lokela ho ela hloko botebo le sebaka sa ho futhumatsa mosebetsi. Haeba mocheso oa mocheso o tebile, sebaka se seholo, ‘me ho futhumatsa ka kakaretso ho etsoa, ​​​​bar e futhumatsang sebōpi se nang le matla a phahameng le maqhubu a tlaase a lokela ho sebelisoa; botebo ba ho futhumatsa ha bo na botebo, sebaka se senyenyane, ‘me ho futhumatsa sebakeng seo ho etsoa, ​​​​’me ho lokela ho khethoa sebōpi se futhumatsang bar se nang le matla a batlang a le tlaase le maqhubu a phahameng.

4. Khetho ea forging futhumatsang sebōpi lokela ho ela hloko ho futhumatsa morethetho oa workpiece. Lebelo la ho futhumatsa la workpiece le hloka ho potlaka, ‘me sebōpi se futhumatsang bar se nang le matla a batlang a le mangata le maqhubu a batlang a phahame a lokela ho khethoa.

5. Khetho ea sebōpi sa ho futhumatsa ka forging e lokela ho ela hloko nako e tsoelang pele ea ho futhumatsa le tekanyo ea ho iketsetsa, le ho etsa qeto ea hore na e na le lisebelisoa tsa ho fepa le ho tsamaisa thepa.

6. Khetho ea libopi tsa ho futhumatsa ka forging e lokela ho ela hloko sebaka sa ho hokahanya pakeng tsa likarolo tsa induction le lisebelisoa. Khokahano e telele, ‘me e bile e hloka tšebeliso ea likhoele tse pholileng ka metsi bakeng sa khokahano. Sebōpi se futhumatsang sa maqhubu a mahareng se nang le matla a phahameng se lokela ho khethoa ka mokhoa o batlang o lekana.

7. Khetho ea libopi tsa forging futhumatsang e lokela ho ela hloko litlhoko tsa ts’ebetso. Ka kakaretso, bakeng sa lits’ebetso tse joalo ka ho tima le ho cheselletsa, matla a lekanyelitsoeng a ka khethoa hore a be manyane mme khafetsa e be holimo. Bakeng sa annealing, tempering le mekhoa e meng, matla a lekanyelitsoeng a lokela ho ba kholoanyane ‘me maqhubu a be tlase. Ba bang; ho phunya ho khubelu, ho chesa ho chesa, ho qhibiliha, joalo-joalo, haeba ts’ebetso e nang le phello e ntle ea ho futhumatsa e hlokahala, matla a lokela ho khethoa a maholoanyane ‘me maqhubu a lokela ho khethoa ka tlaase.
