ʻO ka mea hōʻike paʻakikī ʻo Rockwell kahi ʻano o ka mea hōʻike paʻakikī ʻo Rockwell.Hoʻohana ia i ka ikaika hoʻāʻo liʻiliʻi.Ke hoʻāʻo nei i kekahi mau mea hana liʻiliʻi a lahilahi, me ka hoʻohana ʻana i ka mea hoʻāʻo paʻakikī ʻo Rockwell e alakaʻi i nā waiwai ana pololei ʻole.Hiki iā mākou ke hoʻohana i ka Superficial Rockwell hardness tester.Hiki ke hoʻohana ʻia ka mea hōʻike paʻakikī no ke ana ʻana i nā mea hana me nā papa paʻakikī Superficial.
ʻO kāna kumu hoʻāʻo e like me ka Rockwell hardness tester.ʻO ka ʻokoʻa, ʻo ka ikaika hoʻāʻo mua ʻo 3KG, aʻo ka ikaika hoʻāʻo mua o ka mea hōʻike paʻakikī Rockwell maʻamau ʻo 10KG.
ʻO ke kiʻekiʻe o ka ikaika hoʻāʻo ʻo Rockwell paʻakikī: 15KG, 30KG, 45KG
ʻO ka indenter i hoʻohana ʻia i ka Superficial Rockwell hardness tester ua kūlike me ka Rockwell hardness tester:
1. 120 degree diamond cone indenter
2. 1.5875 mea hookui kinipopo kila
Pākuʻu Pōhakuana unahi mea ho'āʻo paʻakikī:
HR15N, HR30N, HR45N, HR15T, HR30T, HR45T
(Ua ana ka unahi N e ka indenter daimana, a ua ana ka unahi T e ka indenter pōpō kila)
Hōʻike ʻia ka paʻakikīe like me: waiwai paakiki me ka unahi Rockwell, no ka la'ana: 70HR150T
15T 'o ia ho'i he indenter kinipōpō kila me ka ikaika ho'ā'o piha o 147.1N (15 kgf) a me ka indenter o 1.5875.
Ma muli o ka cha i lunaracteristics, Loaʻa iā Superficial Rockwell nā pono penei:
1. No ka mea, elua onanā poʻo kaomi, kūpono ia no nā mea metala palupalu a paʻakikī.
2. ʻO ka ikaika hoʻāʻo he smʻoi aku ka maikaʻi ma mua o ka mea hōʻike paʻakikī o Rockwell, a he liʻiliʻi loa ka pōʻino Superficial o ka mea hana.
3. ʻO ka liʻiliʻi hoʻāʻo forcHiki iā ia ke hoʻololi i ka Vickers hardness tester, ʻoi aku ka waiwai a me ke kumukūʻai.
4. He wikiwiki ka hana ho'āʻo a hiki keʻike ponoʻia ka mea hana i hoʻopauʻia.
