ʻŌnaehana hoʻāʻo paʻakikī Vickers

Kumu o ka mea hoʻāʻo paʻakikī Vickers

ʻO ka paʻakikī ʻo Vickers kahi maʻamau no ka hōʻike ʻana i ka paʻakikī o ka mea i hāpai ʻia e Robert L. Smith lāua ʻo George E. Sandland i ka makahiki 1921 ma Vickers Ltd. ʻO kēia kekahi ʻano hoʻāʻo paʻakikī e hahai ana i nā ʻano hoʻāʻo paʻakikī ʻo Rockwell a me Brinell.

Kumumanaʻo o ka mea hoʻāʻo paʻakikī Vickers:

Hoʻohana ka mea hoʻāʻo paʻakikī Vickers i kahi ukana o 49.03 ~ 980.7N e kaomi i kahi daimana conical huinaha me kahi kihi pili o 136 ° i loko o ka ʻili o ka mea. Ma hope o ka paʻa ʻana no ka manawa i kuhikuhi ʻia, helu ʻia ka waiwai paʻakikī Vickers ma ke ana ʻana i ka lōʻihi diagonal o ka indentation a me ka hoʻohana ʻana i ke ʻano.

ʻO ka laulā noi ukana o nā ʻano Vickers ʻekolu (micro Vickers):

ʻO ka mea hoʻāʻo paʻakikī Vickers me ka ukana o 49.03 ~ 980.7N he kūpono ia no ke ana ʻana i ka paʻakikī o nā ʻāpana hana nui a me nā papa ʻili hohonu.

ʻO ka paʻakikī Vickers haʻahaʻa haʻahaʻa, ka ukana hoʻāʻo <1.949.03N, kūpono no ke ana ʻana o ka paʻakikī o nā ʻāpana hana lahilahi, nā ʻili mea hana, a i ʻole nā ​​​​​​uhi;

ʻO ka paʻakikī Micro Vickers, ka ukana hoʻāʻo <1.961N, kūpono no ke ana ʻana o ka paʻakikī o nā pepa hao a me nā papa ʻili lahilahi loa.

Eia kekahi, i hoʻolako ʻia me kahi Knoop indenter, hiki iā ia ke ana i ka paʻakikī Knoop o nā mea palupalu a paʻakikī e like me ke aniani, nā keramika, ka agate, a me nā pōhaku makamae hana.

Nā pono o ka mea hoʻāʻo paʻakikī Vickers:

1. He ākea ka laulā ana, mai nā metala polokalamu a i nā metala paʻakikī loa, a hiki ke ʻike ʻia, mai kahi mau a ʻekolu tausani mau waiwai paʻakikī Vickers.

2. He liʻiliʻi ka indentation a ʻaʻole ia e hōʻino i ka workpiece, hiki ke hoʻohana ʻia no ka hoʻāʻo ʻana i ka paʻakikī ma nā workpieces i hiki ʻole ke hōʻino ʻia ma ka ʻili o ka workpiece

3. Ma muli o kona ikaika hoʻāʻo liʻiliʻi, hiki i ka ikaika hoʻāʻo liʻiliʻi ke hiki i ka 10g, hiki ke ʻike i kekahi mau ʻāpana hana lahilahi a liʻiliʻi

Nā hemahema o ka mea hoʻāʻo paʻakikī Vickers:

Ke hoʻohālikelike ʻia me nā ʻano hoʻāʻo paʻakikī ʻo Brinell lāua ʻo Rockwell, aia nā koi o ka hoʻāʻo paʻakikī ʻo Vickers no ka laumania o ka ʻili o ka mea hana. Pono kekahi mau mea hana e hoʻopili ʻia, he mea e hoʻopau ai i ka manawa a me ka hana nui.

He pololei loa nā mea hoʻāʻo paʻakikī Vickers a ʻaʻole kūpono no ka hoʻohana ʻana i nā hale hana a i ʻole ma ke kahua, a hoʻohana nui ʻia i nā keʻena hoʻokolohua.

ʻO ka moʻo hoʻāʻo paʻakikī Shandong Shancai Vickers (kiʻi no Wang Songxin)

1. Mea hoʻāʻo paʻakikī Vickers waiwai

2. Hōʻike kikohoʻe a me ka pale pā Vickers mea hoʻāʻo paʻakikī

3. Mea hoʻāʻo paʻakikī Vickers piha piha
