Ngaba isikrufu sokuzibhora siyafana nesikrufu sokuzicofa?

• Yintoni isikrufu sokuzibhora?

Umsila weself-drilling screwikwimo yomsila we-drill. Ayifuni ukucutshungulwa kokuncedisa kwaye inokudityaniswa ngokuthe ngqo, icofe, kwaye itshixelwe kwizinto zokuseta kunye nesiseko, igcina kakhulu ixesha lokwakha. Xa kuthelekiswa nezikrufu eziqhelekileyo, inokuqina okuphezulu kunye nokugcinwa, kwaye ayiyi kukhulula emva kwexesha elide lokuhlanganisa. Kulula ukusebenza ngokusebenzisa ukubhola okukhuselekileyo kunye nokucofa kwindawo enye. Ngokukodwa ekudityanisweni kwazo zonke iindawo ezinje ngokwakha, ulwakhiwo, kunye nezindlu, izikrufu zokuzibhora zezona ziqhoboshileyo zezoqoqosho ngokwemigaqo yokusebenza, iindleko, kunye nokuthembeka.

• Yintoni i-self-tapping screw?

I-self-tapping screws, okanye izikrufu zomsonto okhawulezayo, zizibophelelo zetsimbi ezigqithwa ngokugalela phezu komhlaba. I-self-tapping screws isetyenziselwa kakhulu ukudibanisa phakathi kweepleyiti zetsimbi ezibhityileyo (iipleyiti zentsimbi, iipleyiti zeesaha, njl. njl.). Xa udibanisa, qala wenze umngxuma ongezantsi onemisonto kwindawo edityanisiweyo, uze emva koko ujike isikrufu sokuzicofa kumngxunya ongezantsi odityanisiweyo.

Indlela yokwahlula phakathi kwe-self-drilling screws kunye ne-self-tapping screws?

1) Izikrufu zokuzibhomba kunye nezikrufu zokuzicofa ngokwazo zahlulwa ngemathiriyeli:

Izikrufu zokwembaluhlobo lwezikrufu zomthi, kunye nezikrufu zokuzicofa luhlobo lwezikrufu zokuzitshixa.

2) Izikrufu zokuzibhomba kunye nezikrufu zokuzicofa ngokwazo zahlulwa ngokusetyenziswa kwazo:

Izikrufu zokugaya zisetyenziselwa kakhulu ukulungisa iileyile zetsimbi ezinombala kwizakhiwo zetsimbi kunye neeplati ezincinci. Into ephambili kukuba umsila ufana nomsila we-drill okanye umsila ocacileyo. Xa isetyenzisiwe, akukho msebenzi wokuncedisa ofunekayo, kunye nokugaya, ukucofa, ukutshixa, njl.

I-self-tapping screws inobunzima obuphezulu kwaye ingasetyenziselwa ezinye izinto ezinobunzima obuphezulu, ezifana neepleyiti zentsimbi, njl. Ine-screw-in torque kunye nokusebenza kokutshixa okuphezulu.

3) Izikrufu zokuzibhomba kunye nezikrufu zokuzicofa ngokwazo zahlulwa ngokusebenza kwazo:

I-self-drilling screws zixhobo ezisebenzisa imigaqo ebonakalayo kunye neyemathematika yokujikeleza kwesetyhula ye-inclined surface yento kunye namandla okukhuhlana ukuqinisa ngokuthe ngcembe izinto kunye neengxenye. I-self-drilling screws ibonisa i-drill bit-like point kwi-tip, evumela ukuba bangene kwaye benze umngxuma kwizinto ngaphandle kwemfuneko yokugaya kwangaphambili.

I-self-tapping screwszisetyenziswa kakhulu ukudibanisa iipleyiti zentsimbi ezibhityileyo (iipleyiti zentsimbi, iipleyiti zeesarha, njl. njl.). Xa udibanisa, qala wenze umngxuma ongezantsi onemisonto kwindawo edityanisiweyo, uze emva koko ujike isikrufu sokuzicofa kumngxunya ongezantsi odityanisiweyo.
