Maboti Azitsulo Zosapanga dzimbiri: Maboti a Hex ndi Makalasi azinthu

2026-08-05

1. Mawu Oyamba

Maboti achitsulo chosapanga dzimbiri amaphatikiza kukana dzimbiri ndi mphamvu zamakina, kuwapangitsa kukhala ofunikira pomangamanga, apanyanja, pokonza chakudya, komanso m'mafakitale azachipatala. Mosiyana ndi zomangira zitsulo za kaboni zomwe zimafuna zokutira zoteteza, chitsulo chosapanga dzimbiri chimapeza kukana kwake kwa dzimbiri kuchokera pagawo lodzichiritsa la chromium oxide. Bukuli likuphatikiza mbali ziwiri zofunika kwambiri: kapangidwe ka bolt hex ndi kusankha kalasi yachitsulo chosapanga dzimbiri.

2. Maboti a Hex

Maboti a Hex amakhala ndi mutu wambali zisanu ndi chimodzi womwe umathandizira kusamutsa kwa torque moyenera kudzera pa ma wrenches kapena sockets. Kapangidwe kake kamakhala ndi mutu wa hexagonal, shank yosawerengeka, gawo la ulusi, ndi nsonga yopindika. Ubwino waukulu umaphatikizapo kuchuluka kwa torque, kupezeka kwapadziko lonse lapansi, kupanga bwino, kugwiritsanso ntchito, komanso kutsatira miyezo yapadziko lonse lapansi (ISO 4014, DIN 933, ASTM A325).

Table 1. Standard Hex Bolt Sizes (Stainless Steel)

Kukula mwadzina	Ulusi (TPI)	Kukula kwamutu (mm)	Mphamvu ya Tensile (MPa)
1/4 - 20	20	11.1	520
3/8 - 16	16	14.3	520
1/2 - 13	13	19.1	520
3/4 - 10	10	28.6	520

3. Maphunziro a Zitsulo Zosapanga dzimbiri

Zomangira zitsulo zosapanga dzimbiri zimagawidwa m'mabanja anayi: austenitic (304, 316 - non-magnetic, high corrosion resistance), ferritic (430 - magnetic, economical), martensitic (410 - hardenable, moderate corrosion), ndi mpweya wouma (17-4PH - mphamvu yayikulu). Pansi pa ISO 3506, magiredi amagwiritsa ntchito nambala yachilembo pomwe A = austenitic, C = martensitic, ndipo manambala amatanthawuza gulu lamphamvu lamphamvu (50/70/80).

Table 2. Common Stainless Steel Grades for Bolts

Gulu	Kalasi ya ISO	Tensile (MPa)	Kukaniza Kudzila.	Zofunika Kwambiri	Kugwiritsa Ntchito
304	A2-70	700	Zabwino	18% Kr, 8% Ni	General cholinga, chakudya
316	A4-70	700	Zabwino kwambiri	16% Cr, 10% Ni, 2% Mo	Marine, mankhwala, mankhwala
410	C3-80	550	Wapakati	12% Cr	Zovala, ma valve
17-4 PH	A4-80	800	Zabwino	16% Cr, 4% Ni, 4% Cu	Zamlengalenga, zamphamvu kwambiri

3.1 Kusankhidwa kwa Maphunziro ndi Chilengedwe

Table 3. Makalasi Ovomerezeka ndi Malo Othandizira

Chilengedwe	Gulu lovomerezeka	Chifukwa
M'nyumba / Zouma	304 (A2)	Zokwanira pamtengo wotsika
Panja / Pagombe	316 (A4)	Mo amakana kuukira kwa chloride
Chomera cha Chemical	316L / 904L	Kulimbana kwakukulu kwa asidi
Zofunika Zamphamvu Kwambiri	17-4PH (A4-80)	Mvula-yowuma

Maboliti Osapanga dzimbiri a Hex Bolts ndi Makalasi azinthu

4. Mfundo zazikuluzikulu

Galling: Makalasi a Austenitic (304, 316) amakonda kugwidwa ndi ulusi pakumangitsa. Gwiritsani ntchito mankhwala oletsa kugwidwa kapena ma giredi osiyanasiyana (A2 bolt yokhala ndi A4 nut) kuti muchepetse.

Kukonda: Chithandizo cha Acid (ASTM A967) chimachotsa chitsulo chaulere ndikuwonjezera gawo la okusayidi, ndikuwongolera kukana kwa dzimbiri pambuyo popanga.

Magnetism: Magiredi a Austenitic sakhala ndi maginito akamalumikizidwa koma amatha kukhala maginito pang'ono pambuyo pozizira. Ferritic ndi martensitic giredi ndi mwachibadwa maginito.

5. Mapeto

Maboti osapanga dzimbiri a hex amaphatikiza kapangidwe kake ka geometric ndi kusinthasintha kwazitsulo. Kuchokera ku Giredi 304 yazachuma kuti igwiritsidwe ntchito wamba mpaka 17-4PH yamphamvu kwambiri pakugwiritsa ntchito movutikira, kufananiza giredi yolondola kumalo ogwirira ntchito kumatsimikizira kugwira ntchito bwino komanso moyo wautali.

Palibe. Kenako.
