Dacromet Hex Nuts-Tekinike Intangiriro 

1. Intangiriro

Imbuto ya Hexagonal (hex nuts) iri mubintu bikoreshwa cyane muguteranya imashini, ubwubatsi, amamodoka, hamwe ninganda zikoreshwa. Iyo uhujwe nubuvuzi bugezweho nka Dacromet coating, bitanga imbaraga zidasanzwe zo kurwanya ruswa mugihe gikomeza kwihanganira ibipimo byuzuye hamwe nubusugire bwubukanishi.

1.1 Imbuto za Hex ni iki?

Imyunyungugu ya hex ni ubwoko bwihuta bufite imiterere ya mpande esheshatu nu mwobo imbere. Igishushanyo cyimpande esheshatu zituma porogaramu ikoreshwa neza ikoresheje imirongo isanzwe cyangwa socket. Ibinyomoro bya Hex mubusanzwe bikozwe hakurikijwe amahame mpuzamahanga nka ISO 4032 (stil 1 isanzwe isanzwe), DIN 934, cyangwa ASME B18.2.2, ikubiyemo ubunini bwubunini bwa metero nubwami.

Ibyingenzi byingenzi bya geometrike birimo diameter yumutwe (d), ikibanza (P), ubugari hejuru yamagorofa (s), ubugari hejuru yinguni (e), nuburebure bwimbuto (m). Ibyiciro byumutungo (urugero, 8, 10, 12 kubyuma) bisobanura imbaraga zubukanishi kugirango zihuze amanota ya bolt.

1.2 Incamake yububiko bwa Dacromet

Dacromet ni amazi ashingiye ku mazi, adafite amashanyarazi ya zinc-aluminium flake yatunganijwe mu myaka ya za 70. Igizwe na zinc itatanye neza na flake ya aluminiyumu ihagarikwa muri chromate idasanzwe (cyangwa chromium idafite). Bikoreshwa cyane cyane muburyo bwa dip-spin cyangwa spray hanyuma bigakizwa hafi ya 280–320 ° C, ikora inanutse (mubisanzwe 5-12 mm), imwe, firime irinda ifeza-imvi.

Bitandukanye na electroplating gakondo cyangwa hot-dip galvanizing, Dacromet itanga uburinzi bwangirika bwangirika nta hydrogène ishobora kwanduza-bigatuma bikenerwa cyane cyane bifata imbaraga nyinshi (icyiciro cya 10.9 na 12.9).

2. Ikoranabuhanga rya Dacromet

2.1 Ibigize n'imiterere

Igipfundikizo kigizwe nibice byinshi bya zinc na aluminiyumu bihujwe na matrix idasanzwe. Iyi miterere ya lamellar itera inzitizi nyinshi zumubiri zirwanya ubushuhe hamwe na ion zangirika, mugihe zinc itanga uburinzi (galvanic). Aluminium yongerera inzitizi no kurwanya ubushyuhe.

Igishushanyo cya 2. Byoroheje byubatswe byinshi byuburyo bwa Dacromet itwikiriye ibyuma byubatswe

2.2 Uburyo bwo gusaba

Inzira zisanzwe zikurikirana ni:

1. Gutegura ubuso - kugabanuka kwa alkaline no gusukura (nta gufata aside).
2. Gukoresha igipfundikizo - kwibiza cyangwa gutera amazi ya zinc-aluminiyumu.
3. Centrifuging - kuvanaho igipfunsi kirenze kugirango ubone ubunini bumwe.
4. Gukiza - guteka kuri ~ 300 ° C muminota 15-30 kugirango ukore firime yuzuye idasanzwe. Amakoti menshi arashobora gukoreshwa kumanota yo hejuru.

2.3 Inyungu zingenzi

• Kurwanya ruswa idasanzwe: 1.000-2000 + amasaha yumunyu (ASTM B117) kugeza ingese itukura - mubisanzwe inshuro 5-10 kurenza isahani isanzwe.
• Nta hydrogene yinjira: Inzira itari electrolytike ifite umutekano ku byuma bikomeye (10.9 / 12.9).
• Gupfundikanya neza (5-12 μ m): Irinda urudodo rukwiye kandi rufite ubunini; nta mpamvu yo gukabya.
• Kurwanya ubushyuhe bwinshi: Bihamye kugeza 300 ° C serivisi ikomeza.
• Gukwirakwiza kimwe: Kwinjira cyane mubiruhuko, insanganyamatsiko, hamwe na geometrike igoye ukoresheje dip-spin.
• Coefficients zihoraho: Irashobora guhuzwa hamwe na kote yamavuta kugirango igenzurwe neza.

Igishushanyo 3. Kugereranya byerekana imikorere yumunyu-spray

2.4 Kugereranya nandi mwenda

Imbonerahamwe 1. Kugereranya imikorere yimyenda isanzwe yihuta

3. Ibiti bya Hex - Ibipimo, Ibipimo & Imbaraga

3.1 Ibipimo mpuzamahanga

Ibipimo bikunze kugaragara kuri metric hex nuts ni ISO 4032 (style 1 nuts isanzwe) hamwe na kera ariko iracyakoreshwa cyane DIN 934.Ibipimo bisobanura ibipimo, ubworoherane, hamwe n amanota y'ibicuruzwa (A, B, C). Ibyiciro byumutungo wibyuma byerekanwe muri ISO 898-2 (urugero, ibyiciro 6, 8, 10, 12).

Icyitonderwa: DIN 934 na ISO 4032 biratandukanye gato mubipimo byambukiranya ubunini (urugero, M10, M12, M22). Buri gihe ugenzure guhuza iyo kuvanga ibipimo.

3.2 Ibipimo bisanzwe (ISO 4032 Imiterere 1)

Imbonerahamwe 2. Ibipimo byatoranijwe byerekana ibipimo (ISO 4032, mm). s = ubugari hejuru y'amagorofa; e = ubugari hirya no hino; m = uburebure.

3.3 Ibyiciro byumutungo & Guhuza

Imbuto zigomba guhuzwa na bolt imbaraga kugirango zemeze ko kunanirwa muburyo bugenzurwa (nibyiza muri bolt). Guhuza bisanzwe munsi ya ISO 898-2:

• Icyiciro cya Bolt 8.8 → Ibyiciro 8 cyangwa birenze
• Bolt icyiciro 10.9 → Imyunyu ngugu 10 cyangwa irenga
• Icyiciro cya Bolt 12.9 → Ibyiciro 12

Ipitingi ya Dacromet ifite agaciro cyane mubyiciro 10 na 12 byimbuto kuko inzira itangiza nta ngaruka ya hydrogène ishobora kwanduza ibikoresho bikomeye.

4. Porogaramu ya Dacromet Hex Nuts

Dacromet isize hex nuts iruta ahantu hose irwanya ruswa nyinshi, iringaniza, hamwe nubwizerwe bukenewe icyarimwe:

Imodoka & Ubwikorezi

Ibice bya Chassis, sisitemu yo guhagarika, guteranya feri, ibyuma bifata moteri, hamwe nibice biri munsi yumunyu wumuhanda nubushyuhe bwinshi.

Ingufu z'umuyaga & Ibikorwa Remezo

Iminara ya bolts hamwe na fondasiyo ya fondasiyo ya turbine yumuyaga no kumurongo, aho umunyu-spray ushobora kurenza amasaha 2000 yo gukingirwa.

Ubwubatsi & Imashini Ziremereye

Guhuza imiterere, ibikoresho byubuhinzi, imashini zicukura amabuye y'agaciro, hamwe n’ibikoresho byo hanze bitewe n’ikirere n’imiti.

Ibidukikije byo mu nyanja & Shimi

Icyuma cyibikoresho, urubuga rwo hanze, hamwe nibikoresho byo gutunganya aho imyenda gakondo yangirika vuba.

4.1 Amabwiriza yo Guhitamo

Imbonerahamwe 3. Guhitamo byihuse kubutaka bwa hex nuts

5. Umwanzuro

Dacromet hex nuts ihuza imashini yizewe hamwe na geometrie isanzwe ya nuts gakondo ya hexagonal hamwe no kurinda ruswa yateye imbere ya tekinoroji ya zinc-aluminium. Ipfundikizo yoroheje, imwe irinda guhuza urudodo no guhorana umuriro, mugihe utanga imikorere yumunyu-spray urenze kure isahani isanzwe ya zinc kandi nta mpungenge za hydrogène.

Ku ba injeniyeri n'abaguzi bagaragaza ibyuma bifata ibinyabiziga, ingufu zishobora kongera ingufu, ibikorwa remezo, cyangwa ibidukikije bikaze mu nganda, imbuto za Dacromet zometseho hex zitanga impuzandengo yerekana ko iramba, itomoye, hamwe nigihe kirekire-cyiza-cyiza.

Mugihe uhitamo ibicuruzwa, burigihe wemeze igipimo cyo gutwikira (A / B cyangwa bihwanye), igipimo cyumunyu-spray, coefficient de fraisse (niba ikoreshwa ryamavuta yo hejuru)

Reba & Ibipimo: ISO 4032, ISO 898-2, DIN 934, ASTM B117, impapuro zerekana amakuru ya sisitemu ya Dacromet / zinc-flake (urugero, DACROMET®, GEOMET®).
