ʻO ka code no ka paʻakikī paʻakikīʻo H. E like me nāʻano hoʻokolohua paʻakikī e like me nāʻano hana paʻakikī (HR),ʻo ka HRC). ʻO ka HB he mau mea nui o nā noi noi, a he kūpono ka HRC no nā mea me ka paʻakikī kiʻekiʻe, e like me ka paʻakikī o ka wela. ʻO kaʻokoʻa kaʻokoʻa o ka mea i loaʻa i ka mea paʻakikī o ka hana paʻakikī. ʻO ka Tester paʻakikīʻo Bririnen i loaʻa i ka pōkā,ʻoiaiʻo ka pōhaku paʻakikī paʻakikīʻo ka pōhakuʻo Tester he daimana.
HV-kūpono no ka loiloi microscope. ʻO nā Vickers paʻakikī (HV) E kaomi i ka papa hana me ka ukana ma lalo o 120kg a me kahi kihi corcte radite a me kahi kihi o ka manawa he 66 °. ʻO ka wahi ākea o ka pā o ka waihona i hoʻokaʻawaleʻia e ka waiwai waiwai,ʻo ia ka waiwai o nā vickers paʻakikī (HV). Ua hōʻikeʻia nā paʻakikī Vickers e like me HV (e pili ana iā GB / T4340-1990), a hanaʻia nā hiʻohiʻona likeʻole.
ʻO HL Portable Tester Tester ke kūpono no ke anaʻana. Hoʻohana ia i ka hope o ka pōpō popo e hoʻokō i kaʻaoʻao paʻakikī a hana i kahi bounce. Kuhiʻia ka paʻakikī o ka hoʻokūkū o ka wikiwiki o ka punch i ka 1mm mai ka sample i ka wikiwiki. ʻO keʻano he: Leeb paʻakikī HL = 1000
Hiki ke hoʻololiʻiaʻo Pester HandTity Tester Tester i loko o Brinell (HB), Rockwell (HR), star (HL). A iʻole e hoʻohana i nā loina leeb e hana pololei i ka waiwai paʻakikī me Bririnel (HB), Rockwell, Lee (HS).
HB - Brrinel paʻakikī:
Ua hoʻohana pinepineʻiaʻo Brinel Ua hoʻohana pinepineʻiaʻo Rockwell i nā mea paʻakikī (HRC) no nā lako me ka paʻakikī kiʻekiʻe, e like me ka paʻakikī ma hope o ka mālama wela, etc.
ʻO Brinel ʻO kahi pōpō kila paʻakikī a iʻole ka pōloli pōkole o kahi papa o kekahi o kahi inika i hoʻopaʻaʻia i loko o kaʻaoʻao metala e ho'āʻoʻia. Mālamaʻia ka ukana hōʻike no ka manawa i kohoʻia, a laila hoʻihoʻiʻia ka ukana eʻae i ka'āpana o ka'awa'ī i kaʻinoʻino. ʻO ka waiwai paʻakikīʻo Brinel ʻO ka maʻamau, kahi pahu kila paʻakikī o kahi nui o kahi nui (maʻamau 10mm i loko o ka'āpana) i loko o kahi paʻa (maʻamau 3000kg) a mālamaʻia no kahi manawa. Ma hope o ka laweʻiaʻana o ka ukana,ʻo ka pae o ka ukana i ka wahi indentation he waiwai paʻakikīʻo Binelly (HB)
E hoʻoholo i ka paʻakikīʻo Rockwell i ka nui o ka uku paʻakikī i hoʻokumuʻia ma luna o ka hohonu o ka paleʻana o ka pepa. Ua hoʻohanaʻiaʻo 0.002 MM ma keʻano he paʻakikī paʻakikī. I ka wa e hb> Hoʻohana ia i kahi kāʻei daimana me ka manamana Rula o 120 ° a iʻole ka pahu kila i lalo o kahi'āpana o ka inding o ka huhū. Wahi a ka paʻakikī o ka mea hōʻike hōʻike, ua hōʻikeʻia ma nā'āpanaʻekolu:
HRA:ʻo ia ka mea paʻakikī i loaʻa ma o ka hoʻohanaʻana i kahi ukana 60KG a me kahi mea i hoʻohanaʻia, e hoʻohanaʻia no nā mea paʻakikī loa (etc.).
HRB:ʻO ia ka mea paʻakikī i loaʻa ma o ka hoʻohanaʻana i kahi ukana 100kg a me kahi pahu kila i hoʻohanaʻia me ka mea paʻakikī.
HRC:ʻO ia ka mea paʻakikī i loaʻa ma o ka hoʻohanaʻana i kahi ukana 150kg a me kahi mea i hoʻohanaʻia no ka mea paʻakikī.
Kahi mea hou aʻe:
1.Hrc ke kumuʻo Rockwell paʻakikī paʻakikī C Sigle.
2.hrc a me hb i hoʻohana nuiʻia i ka hanaʻana.
3.HRC e pili ana i ka HRC 20-67, kūlike me HB225-650,
Ināʻoi aku ka paʻakikī ma mua o kēiaʻano, e hoʻohana i ka paʻakikī o Rockwell paʻakikī i kahi Scale Hra,
Inā haʻahaʻa loa ka paʻakikī ma mua o kēiaʻano, e hoʻohana i ka paʻakikī o Rockwell paʻakikī B Scale HRB,
ʻO ka palena kiʻekiʻe o Briend Wirell he HB650,ʻaʻole hiki ke kiʻekiʻe aʻe ma mua o kēia waiwai.
4.ʻO ka mendenter o Rockwell paʻakikī paʻakikīʻo Tester C Sigle C Sigle he cone damia me kahi kaula vertex a me kahi kihi o ka 120 degere. ʻO ka uku hōʻike hōʻike he waiwai. ʻO ka papa inoa Kina he 150 kgf. ʻO ka maniha o nā mea paʻakikī o ka binel Hoʻololi ka ukana o ka hoʻokolokolo me ka'āpana o ka pōpō, e neʻe ana mai 3000 a 31.25 kgf.
5. He liʻiliʻi loa ka huhū paʻakikīʻo Rockwell, aʻo keʻano waiwai i hoʻopaʻaʻia. Pono ia e ana i kekahi mau wahi e loaʻa ai ka waiwai maʻamau. He kūpono kūpono no nā huahana a me nā'āpana a me nā'āpana a me nā'āpana a iʻole i heluʻia e like me ka hanaʻoleʻana. ʻOi aku ka nui o ka huhū paʻakikī,ʻo ka waiwai nui,ʻaʻole kūpono ia no nā huahana a pauʻole, aʻaʻole i heluʻia e like me ka hanaʻoleʻana.
6.ʻO ka waiwai paʻakikī o ka paʻakikī paʻakikī he helu heluʻoleʻia me nā'āpanaʻole. (No laila, he hewaʻole ke kāhea aku i ka paʻakikī o ka pôpeku ma keʻano he nui.
7. Ua hōʻike pololeiʻiaʻo Rockwell paʻakikī ma ka kelepona a hōʻikeʻia paha. He mea maʻalahi ke hana, wikiwiki a intuitive, a kūpono no ka hana nui. Ponoʻo Binel Excell i kahi mikroscope e ana i ka laulā o ka heluʻana, a laila e nānā i ka papaʻaina a iʻole ka heluʻana,ʻoi aku ka nui o nā cumbers.
8. Ma lalo o kekahi mau kūlana, hiki ke hoʻopiliʻia ka HB a me HR a me HRC ma ke nānāʻana i ka papaʻaina. Hiki ke hoʻopaʻaʻia ka'ōlelo noʻonoʻo noʻonoʻo noʻonoʻo e like me: 1hrc≈1 / 10hb.
ʻO ka hōʻike paʻakikī he ala maʻalahi a maʻalahi hoʻi keʻano hoʻokolohua maʻalahi ma ka hōʻikeʻana i ka waiwai waiwai. I mea e hoʻohana ai i ka hōʻike paʻakikī e hoʻololi i kekahi mau hoʻokolohua waiwai mechanical,ʻoi aku ka maikaʻi o ka pilina ma waena o ka paʻakikī a me ka ikaika i ka hana.
Ua hōʻoiaʻiʻoʻia ka hoʻomaʻamaʻaʻana ma kahi o ka pilina pili ma waena o nā waiwai paʻakikī o nā mea paʻakikī a me nā waiwai ikaika a me ka waiwai ikaika. No ka mea ua hoʻoholo ka koʻikoʻi paʻakikī e ka pale o ka plasformation deform i ka wā o ka paleʻana a me ke kū kū'ēʻana,ʻoi aku ka kiʻekiʻe o kaʻikepili.
