I-Cold forging, eyaziwa nangokuthi i-cold volume forging, iyinqubo yokukhiqiza kanye nendlela yokucubungula. Ngokuyisisekelo kuyafana nenqubo yokugxiviza, inqubo yokubumba ebandayo yakhiwa ngezinto zokwakha, isikhunta kanye nemishini. Kodwa okokusebenza ekucutshungulweni kokugxiviza ikakhulukazi kuyipuleti, futhi okokusebenza ekucubunguleni okubandayo ngokuyinhloko kuwucingo lwediski. I-Japan (JIS) ebizwa ngokuthi i-cold forging (i-cold forging), i-China (GB) ebizwa ngokuthi i-cold heading, i-external screw factory efana nokubiza ikhanda.

Isakhiwo sensimbi ibhawudi elisetshenziswayo lizohluka ngokuya ngamandla okusetshenziswa okuhlukile kwendawo nalo lihlukile, ngakho-ke ungahlulela kanjani izinga lamandla? Ibanga lamandla lesakhiwo sensimbi: Ibanga lamandla lebhawodi lesakhiwo sensimbi lokuxhumana kwesakhiwo sensimbi ngu-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, njll. Ibanga lamandla lebhawodi lesakhiwo sensimbi liqukethe izingxenye ezimbili izinombolo, ngokulandelana zimele inani lamandla e-tensile kanye nesilinganiso se-flexion sensimbi yesakhiwo sebholithi yensimbi.

Ukuze kukhiqizwe izinsimbi zokubopha ngezikulufo, ukwelapha okungaphezulu kuyinqubo engenakugwemeka, abathengisi abaningi ekubuzeni mayelana nezixhumi zokubopha isikulufu, indlela yokwelashwa kwendawo, inethiwekhi evamile ngokolwazi olufingqiwe olumayelana nobuso bezinsimbi zokubopha isikulufa izindlela ezivamile zokucubungula kunezinhlobo eziyisishiyagalombili. amafomu, afana nalokhu: omnyama (oluhlaza okwesibhakabhaka), i-phosphating, i-zinc dip eshisayo, i-dacromet, i-galvanized kagesi, i-chrome plating, i-nickel ne-zinc impregnation. I-fastener screw surface treatment ngokusebenzisa indlela ethile yokwenza isendlalelo esisibekelayo phezu kwendawo yokusebenza, inhloso yaso ukwenza ubuso bomkhiqizo bube buhle, bube nomthelela wokunqanda ukugqwala.
