1. Mawu Oyamba

Gulu la 10.9 Dacromet hexagon head bolts amaimira gulu lapamwamba la zomangira zamphamvu kwambiri zomwe zimagwiritsidwa ntchito kwambiri pamagalimoto, zomangamanga, mphamvu zamphepo, makina olemera, ndi ntchito za zomangamanga. Maboti awa amaphatikiza zinthu zitatu zofunika kwambiri: magwiridwe antchito apamwamba a gulu la katundu 10.9, mawonekedwe osinthika komanso odalirika a kapangidwe ka mutu wa hexagonal, komanso chitetezo chambiri cha dzimbiri choperekedwa ndi zokutira za Dacromet (zinc-flake).

2. Kalasi ya katundu 10.9 - Mphamvu zamakina

Kalasi ya katundu 10.9 imatanthauzidwa mu ISO 898-1 (Mechanical properties of fasteners zopangidwa ndi carbon steel ndi alloy steel - Gawo 1: Bolts, screws and studs). Mawu akuti "10.9" akuwonetsa mphamvu yamphamvu ya 1000 MPa ndi chiŵerengero cha zokolola za pafupifupi 0,9. Zomangira izi nthawi zambiri zimapangidwa kuchokera kuzitsulo zozimitsidwa komanso zotenthedwa (monga 35CrMo, 42CrMo, kapena zitsulo za boron) ndipo ndizoyenera kugwiritsa ntchito zomangira komanso zosunthika.

Katundu Wamakina Ofunikira (ISO 898-1)

Katundu	Mwadzina	Zochepa	Chigawo
Mphamvu yamphamvu Rm	1000	1040	MPa
Kupsinjika kwaumboni / mphamvu zokolola Rp0.2	900	940	MPa
Kupanikizika pansi pa umboni wa Sp	830	—	MPa
Elongation pambuyo fracture A	—	9	%
Vickers kuuma kwa HV	—	320-380	HV
Rockwell kuuma HRC	—	32-39	Mtengo wa HRC

Poyerekeza ndi kalasi ya katundu 8.8, Gulu la 10.9 limapereka pafupifupi 25-30 % mphamvu zamakokedwe apamwamba komanso kuthekera kwapang'onopang'ono kwambiri. Izi zimapangitsa kukhala chisankho chokondedwa pamalumikizidwe ofunikira mu injini, chassis, zitsulo zamapangidwe, ndi zida zolemetsa komwe kumafunikira kuchepetsa thupi komanso kuchita bwino kwambiri.

3. Hexa Maboliti — Mapangidwe & Miyezo

Zomangira zamutu za hexagon (zomwe nthawi zambiri zimatchedwa hex bolts) ndizomwe zimagwiritsidwa ntchito kwambiri zomangira zakunja. Mutu wambali zisanu ndi chimodzi umapereka ma torque abwino kwambiri okhala ndi mawotchi otseguka kapena ma socket wrenches ndipo amalola mwayi wofikira kumakona angapo. Miyezo iwiri ikuluikulu yapadziko lonse lapansi imayang'anira ma metric hex bolts:

TS EN ISO 4014 / DIN 931 - Zomangidwa pang'ono (shank pansi pamutu)
ISO 4017 / DIN 933 - Yopangidwa mokwanira

Mabowuti a ulusi wapang'ono (ISO 4014) amakondedwa pamene ndege yometa ubweya imayenera kugwira ntchito pa shank yosawerengeka kuti izitha kumeta ubweya wambiri, kapena pakafunika kutalika kokhomerera koyenera. Maboti a ulusi wathunthu amasankhidwa kuti azitha kusinthasintha komanso kutalika kwake kutha kukhala ndi bowo kapena nati.

Makulidwe Odziwika (Kukula Osankhidwa, ISO 4014 / DIN 931)

Kukula mwadzina	Kutalika (mm)	Pamwamba pa Flats (mm)	Kutalika Kwamutu k (mm)	Utali Waulusi b ≤125 mm	Kukula kwa Wrench
M8	1.25	13	5.3	22	13
M10	1.5	16/17	6.4	26	16/17
M12	1.75	18/19	7.5	30	18/19
M16	2.0	24	10.0	38	24
M20	2.5	30	12.5	46	30
M24	3.0	36	15.0	54	36

Zindikirani: Miyezo yamalo ophwanyika imatha kusiyana pang'ono pakati pa mndandanda wa ISO ndi DIN wamitundu ina (monga M10 ndi M12). Tsimikizirani nthawi zonse mulingo woyenera pakugwiritsa ntchito. Zogulitsa A ndi B zimatanthawuza kulolerana kwapakati; Gulu A ndi lolimba ndipo nthawi zambiri limagwiritsidwa ntchito popanga ma diameter ang'onoang'ono.

Ubwino wa Hexagon Head Design

Kuthekera kwakukulu kwa torque yokhala ndi zida zokhazikika
Kufikika kwabwino m'mipata yotsekeka kuchokera pamakona asanu ndi limodzi
Kupanga kotsika mtengo komanso kupezeka kofala
Zimagwirizana ndi mitundu yonse ya mtedza, ma washer, ndi zida zotsekera

4. Kupaka kwa Dacromet - Kutetezedwa Kwambiri kwa Corrosion

Dacromet ndi ukadaulo waukadaulo wa zinc-flake (poyamba wopangidwa ndi Metal Coatings International). Zimapangidwa ndi zinc ndi aluminium flakes zoyimitsidwa mu binder, zomwe zimagwiritsidwa ntchito ndi dip-spin kapena njira zopopera ndikuchiritsidwa pafupifupi 300-340 ° C. Kanema wowonda, wandiweyani, wa siliva-grey amapereka chitetezo chambiri chambiri popanda chiopsezo cha hydrogen embrittlement - mwayi wofunikira kwa zomangira zolimba kwambiri monga Gulu la 10.9 ndi 12.9.

Makhalidwe Ofunika Kwambiri

Parameter	Mtengo Wabwino / Kachitidwe
Kupaka makulidwe	5 – 15 μm (Giredi A ≈ 5 μm; Gulu B ≈ 8 μm)
Kupopera mchere wapakati (ASTM B117)	500 - 1000+ maola kuti dzimbiri lofiira (malingana ndi kalasi)
Kukana kutentha	Kufikira 300 ° C mosalekeza (kuphimba kumakhalabe koteteza)
Chiwopsezo cha hydrogen embrittlement	Palibe (ndondomeko yopanda electrolytic, palibe pickling ya asidi)
Coefficient ya kukangana	0.12 - 0.18 (ndi mitundu yosiyanasiyana yamafuta monga Dacromet 500)
Maonekedwe	Metal siliva-imvi; Kuphimba kofanana ngakhale pa ulusi

Kuyerekeza ndi zokutira wamba zina

Mbali	Electro Zinc	Hot Dip Galvanizing	Dacromet
Makulidwe	5-15 m	40-85 m	5-15 m
Kupopera mchere (red dzimbiri)	72-240 h	400-800 h	500-1000+ h
H₂ chiopsezo chotenga kachilomboka	Wapamwamba	Perekani	Palibe
Kugwirizana kwa ulusi	Zochepa	Kukwera (nthawi zambiri kumafuna kuchulukira)	Zochepa
Kukwanira kwa 10.9+	Zochepa	Chenjezo chofunika	Zabwino kwambiri

Chifukwa njira ya Dacromet imaphatikizapo kusakhala ndi electrochemical hydrogen general and no aggressive acid pickling, ndizomwe zimakondedwa (komanso nthawi zambiri zovomerezeka) za Giredi 10.9 ndi zomangira zapamwamba pamagalimoto ndi kapangidwe kake.

5. Ubwino Wophatikizana & Ntchito Zofananira

Mphamvu ya Giredi 10.9, geometry ya mutu wa hexagonal, ndi zokutira za Dacromet zikaphatikizidwa, cholumikizira chomwe chimabwera chimapereka magwiridwe antchito amakina, kumasuka kwa msonkhano, komanso kulimba kwa nthawi yayitali m'malo owononga.

Ubwino Woyambirira

1.High clamp load capability - imathandizira mapangidwe olumikizana opepuka komanso kudalirika kwakukulu pansi pa kugwedezeka ndi katundu wosunthika.

2. Superior corrosion resistance - ntchito yopopera mchere imaposa plating wamba wa zinki ndikusunga ulusi wolondola.

3.Hydrogen-embrittlement yaulere - chinthu chofunikira chotetezera pazitsulo zolimba kwambiri.

4.Kukangana kolamuliridwa - mitundu yosiyanasiyana ya Dacromet yopaka mafuta imapereka maubwenzi odziwikiratu a torque-tension, kukonza kusasinthika kwa msonkhano.

Kukhazikika kwa 5.Thermal - kumakhalabe chitetezo pa kutentha kwapamwamba komwe kumapezeka m'zipinda za injini ndi zipangizo zamakampani.

Magawo Omwe Amagwiritsa Ntchito

Magalimoto: chassis, kuyimitsidwa, kuyimitsidwa kwa injini, zida za powertrain
Mphamvu yamphepo: ma flanges a nsanja, zida za nacelle, nangula wa maziko
Kumanga kwakukulu & zomangamanga: milatho yachitsulo, nsanja zotumizira, njanji
Makina aulimi ndi omanga omwe amagwira ntchito panja
Zida zam'madzi ndi zam'mphepete mwa nyanja (ndi kusankha koyenera)

6. Mapeto

Gulu la 10.9 Dacromet hexagon head bolts imapereka kuphatikizika kodalirika kwa mphamvu zolimba kwambiri, ma geometry okhazikika, komanso kuteteza dzimbiri kwa nthawi yayitali. Pokwaniritsa zofunikira zamakina a ISO 898-1 Kalasi 10.9, mogwirizana ndi miyezo yokhazikika monga ISO 4014, ndikugwiritsa ntchito zokutira za zinc-flake zopanda haidrojeni, zomangira izi zimapatsa mainjiniya yankho lotsimikizika pamalumikizidwe ovuta omwe amakumana ndi zovuta zamakina komanso malo ankhanza.

Zam'mbuyo. Kenako.
