ʻO ka hoʻomaka ʻana o ka pōʻai poʻo Hexagon

Hexagon bolt pili i ka mea hoʻopaʻa i haku ʻia me ke poʻo a me ka wili. Hoʻokaʻawale ʻia ka pahu i ka hao a me ke kila kila e like me ka mea, ʻo ia hoʻi,hexagon-head bolt (ʻāpana ʻāpana)– Papa C a mehexagon-head bolt (lōʻihi piha)– Papa C

ʻO kakaʻina hanaonā kī hexagonpenei:

1、 E ʻoki, e hoʻohana i nā ʻokiʻoki kūikawā e ʻoki i nā mea i hoʻopaʻa ʻia i loko o ka ʻāpana ʻāʻī i loko o nā blanks e pono ai mākou ma kahi ʻaoʻao hoʻokahi.

2, ʻO ka kuʻi mua, ʻo kēia kaʻina hana e kaomi i ka blank me ka pahu hope e kūʻē i ka punch blank, a laila e pana i ka blank ma hope o ka hana mālie.

3、 ʻO ke kuʻi ʻelua, e like me ka ʻanuʻu ma luna, e hoʻokō i ka lua nui make a make extrusion, i lilo ka blank ma hope o ka hana ʻana.

4、 ʻEkolu-kuʻi, ʻo ia ke kolu o ka manawa e hoʻoponopono a kuʻi i ka ʻōpala, hoʻohana i ka hexagonal three-punch die core e ʻoki. Ke hoʻokumu mālieʻia ke poʻo hexagonal o ka mea maka, hoʻokuʻuʻia ka mea maka i loko o ka'ōpala no ke kolu o ka manawa e kuʻi i ka'ōpala. ʻO ka hope, ke ʻoki ʻia ke poʻo hexagonal, pau ka hana.

Hoʻokaʻawale ʻia ka papa hana o nā bolts i hoʻohana ʻia no ka hoʻopili ʻana i ke kila i ʻoi aku ma mua o 10nā māka, me 4.6, 4.8, 5.6, 6.8, 8.8.10.9, 12.9,etc. Mawaena o lakou,bolts o ka papa 8.8a ma luna aʻe ua hana ʻia me ke kila kalapona haʻahaʻa a i ʻole ke kila kalapona maʻamau a mālama ʻia ka wela (quenched and tempered), ka mea maʻamau i kapa ʻia he mau bolts ikaika kiʻekiʻe, a ʻo ke koena i kapa ʻia he mau bolts maʻamau. ʻO ka hōʻailona hana bolt he ʻelua ʻāpana o nā helu, e hōʻike ana i ka waiwai ikaika tensile nominal a me ka ratio ikaika o ka mea bolt. ʻo kahi laʻana:

ʻO nā bolts me ka helu hana o 4.6 mean:

1. ʻO ka ikaika tensile nominal o nā mea bolt hiki i 400MPa;

2. ʻO ka lākiō ikaika o nā mea bolt he 0.6;

3. Nominal yield ikaika o bolt mea hiki i 400 × 0.6=240MPa

Hiki i nā bolts ikaika kiʻekiʻe me ka helu hana o 10.9 ke hiki i kēia ma hope o ka mālama wela:

1. ʻO ka ikaika tensile nominal o ka mea bolt hiki i 1000MPa;

2. ʻO ka lākiō ikaika o nā mea bolt he 0.9;

3. Nominal yield ikaika o bolt mea hiki i 1000 × 0.9=900MPa pae

ʻO ke ʻano o ka papa hana bolt he kūlana honua. ʻO ka hana ʻana o nā bolts me ka pae hana like like ʻole me ka nānā ʻole i kā lākou mea a me kahi kumu. Hiki ke koho wale ʻia ka papa hana ma ka hoʻolālā.
