1) Enwere ike iji Rockwell hardness tester nwalee ike nke mgbidi ọkpọkọ ígwè?
The ule ihe bụ SA-213M T22 ígwè ọkpọkọ na elu dayameta nke 16mm na a mgbidi ọkpụrụkpụ nke 1.65mm.Nsonaazụ ule nke Rockwell hardness tester bụ ndị a: Mgbe ewepụchara oxide na decarburized oyi akwa n'elu ihe atụ na grinder, a na-etinye ihe atụ ahụ na tebụl ọrụ nke nwere ụdị V na Rockwell hardness test e mere ozugbo n'elu elu ya. iji HRS-150S dijitalụ ngosi Rockwell hardness tester na ibu :980.7N.
Mgbe ule ahụ gasịrị, a pụrụ ịhụ na ọkpọkọ ígwè dị na mgbidi ahụ nwere ntakịrị nrụrụ, na nsonaazụ ya bụ: ọnụ ala dị ala nke Rockwell hardness na-eme ka ule ahụ ghara ịdị irè.
Dị ka GB/T 230.1-2018 si kwuo "Nnwale Rockwell Hardness maka ihe ndị dị mma Nkebi 1: Ụzọ nnwale", ike Rockwell bụ 80HRBW na ọkpụrụkpụ kacha nta nke ụdị ahụ bụ 1.5mm.The ọkpụrụkpụ nke sample No.1 bụ 1.65mm, ọkpụrụkpụ nke decarburized oyi akwa bụ 0.15 ~ 0.20mm, na ọkpụrụkpụ nke sample mgbe wepụ decarburized oyi akwa bụ 1.4 ~ 1.45mm, nke dị nso na kacha nta ọkpụrụkpụ nke sample. kpọmkwem na GB/T 230.1-2018.
N'oge ule, n'ihi na sample center adịghị akwado, ọ ga-eme ka aghụghọ (ikekwe-adịghị ahụ anya na gba ọtọ anya) deformation, otú Rockwell hardness tụrụ uru bụ kama ala.
2) Otu esi ahọrọ nke eluRockwellihe nleba anya siri ike maka ịnwale ọkpọkọ ígwè:
Ụlọ ọrụ anyị anwalela ike siri ike nke ọkpọkọ ígwè ahụ ugboro ugboro wee ruo nkwubi okwu ndị a:
Nnwale siri ike Rockwell ma ọ bụ Rockwell hardness test n'elu ọkpọkọ ígwè nwere obere mgbidi.Nkwado mgbidi na-ezughị ezu ga-eme ka nrụrụ ihe atụ pụta ma mee ka nsonaazụ ule dị ala;
Ọ bụrụ na-etinye cylindrical support n'etiti mkpa-mgbidi ígwè tube, n'ihi na ọ pụghị hụ na indenter axis na ibu loading direction na elu nke ígwè anwụrụ perpendicular elu, na elu elu nke ígwè ọkpọkọ na n'elu. a ga-eme ka a ọdịiche nke nkwado cylindrical nke ọdịiche dị n'etiti okirikiri okirikiri nke ígwè ọkpọkọ na cylindrical support elu, ga-emekwa ka ule pụta bụ kama ala.
Tụgharịa nnwale siri ike nke Vickers ka ọ bụrụ nnwale siri ike Rockwell ka emechara ihe nrụpụta ọkpọkọ igwe, ga-enweta uru siri ike Rockwell ziri ezi.
2. Mgbe ewepụchara oxide na decarburization oyi akwa n'elu nke ígwè ọkpọkọ na machining ule ule na elu elu na inlaying ya, Uru bụ ihe ziri ezi tụnyere Superficial Rockwell hardness tester na Rockwell hardness tester.
