Yadda Ake Zaɓar Mai Gwajin Taurin Karfe?

Jagorar Mataki Ɗaya Don Zaɓar Nau'in Da Ya Dace

Zaɓi bisa ga girma biyar: girman kayan aiki, kayan aiki, kewayon tauri, buƙatun daidaito, da yanayin aikace-aikacen. Babu buƙatar damuwa, kawai bi jagorar kuma za ku iya yanke shawara.

I. Da farko, a rarraba zuwa manyan nau'ikan gwajin tauri guda uku

1. Rockwell Hardness Tester (HRC/HRB/HRA)

Ya dace da: ƙarfe da aka kashe, ƙarfe da aka mutu, bearings, kayan aiki, sassan da aka yi wa magani da zafi

Abũbuwan amfãni: babban daidaito, ana amfani da shi sosai a cikin ƙa'idodin ƙasa, kayan aiki na yau da kullun don duba ingancin masana'anta

Rashin amfani: dole ne a ɗauki samfura / nau'in tebur, manyan sassa ba za a iya motsa su ko gwada su a wurin ba

Abin da za a auna:

HRC: ƙarfe mai tauri mai ƙarfi (kayan aiki, kayan aiki, giya)

HRB: tagulla, aluminum, ƙarfe mai ƙarancin carbon, ƙarfe mai laushi

2. Mai Gwajin Taurin Brinell (HB)

Ya dace da: ƙarfe mai siminti, ƙarfe mai siminti, ƙarfe mai aluminum, ƙarfe mai tagulla, sassa masu kauri da aka ƙirƙira

Fa'idodi: babban lanƙwasa, mafi daidaito ga kayan da aka yi da tsatsa da waɗanda ba su da tsari

Rashin amfani: babban shiga, lalatawa, ƙarancin inganci, ya dace da duba tabo na dakin gwaje-gwaje

3. Mai Gwajin Taurin Leeb (HL mai ɗaukuwa zuwa HRC/HB/HV)—YY251D Leeb Taurin Gwaji

Ya dace da: manyan sassa, gwajin wurin aiki, sassan da ba za a iya wargaza su ba, manyan ƙuraje, birgima, shafts

Fa'idodi: na hannu da na ɗaukuwa, ba ya lalatawa, babu buƙatar ɗaukar samfura, ana iya amfani da shi a matsayi a tsaye, a kwance, ko a sama

Rashin amfani: ɗan ƙaramin daidaito fiye da Rockwell na tebur, manyan kurakurai ga ƙananan sassa masu bango da sirara

II. Zaɓi bisa ga yanayin aikace-aikace (mafi dacewa)

Yanayi na 1: dakin gwaje-gwaje na bita, duba ingancin kayan da ke shigowa / maganin zafi, ana buƙatar cikakken daidaito Zaɓi mai gwajin taurin kai na Rockwell na tebur

An fi so ga masana'antun kayan aiki na yau da kullun, masana'antun yin amfani da na'urar dumama, da masana'antun sarrafa zafi.

Yanayi na 2: ƙarfe mai siminti, siminti, ƙarfe mai ƙarfe na aluminum, sassan da aka ƙera da ƙarfi

Zaɓi mai gwajin taurin Brinell

Yanayi na 3: manyan sassan da ba za a iya motsa su ba, gwajin wurin, molds / birgima / manyan shafts Dole ne a zaɓi mai gwajin taurin Leeb mai ɗaukuwa

Yanayi na 4: ƙananan sassa, siraran zanen gado, taurin saman yadudduka masu kauri da nitride Zaɓi na'urar gwajin taurin Vickers (HV)

Ya dace da: zanen gado mai siriri, gefunan kayan aiki, shafi, yadudduka masu tauri.

III. Zaɓi bisa ga kauri / girman kayan aikin

Manyan sassa masu nauyi, masu motsi, da marasa motsi → Leeb

Ana iya sanya samfuran yau da kullun, ƙananan sassa, akan tebur → Rockwell

Siraran sassa < 3mm, yadudduka masu tauri a saman → Vickers

Fitar da babu komai, kayan da ba su da tsari → Brinell

IV. Zaɓi bisa ga matakin tauri

Kayan laushi: aluminum, jan ƙarfe, ƙarfe mai ƙarancin carbon → HRB / HB

Matsakaici mai tauri: ƙarfe mai kauri da kuma mai laushi, ƙarfe mai tsari → HRC / HB

Babban tauri: matattun da aka kashe, kayan aiki, bearings → HRC / HV

Yankakken saman da aka yi da sirara sosai / yadudduka masu kauri → HV Vickers
