Leeb Hardness Tester
Kugeza ubu, dieb testers ikomeye yakoreshejwe cyane mugupima ubukana. Leeb Hardness Tester yemeje ihame ryo gupima imbaraga zingirakamaro kandi rikoresha ikoranabuhanga rya mudasobwa kugirango tumenye miniturution hamwe na elegitoronisation yo gufata nabi. Biroroshye kandi byoroshye gukoresha, gusoma birakabije, kandi ibisubizo byikizamini birashobora guhinduka byoroshye indangagaciro zikomeye, bityo birakirwa cyane.
Ibikoresho byinshi ni ibikorwa binini-kuri-binini, bimwe bipima toni nyinshi, kandi ntigishobora kugeragezwa kuntebe-hejuru. Ikigeragezo gikomeye cyo gupima cyane cyane gikoresha ukwayo kumeza inkoni y'ibizamini cyangwa ibizamini bifatanye. Ariko, yaba bar ikizamini cyangwa ikizamini cyangwa ibizamini birashobora gusimbuza burundu ibikorwa. Nubwo ari itanura rimwe ryicyuma, inzira yo kwita hamwe nuburyo bwo kuvura ni bumwe. Kubera itandukaniro rikomeye mubunini, igipimo cyo gushyushya, cyane cyane igipimo cyo gukonjesha, kizaba gitandukanye. Biragoye gutuma bombi bafite ubukana rwose. Kubera iyo mpamvu, abakiriya benshi biremera cyane kandi bizera gukomera kw'imirimo ubwayo. Ibi bisaba gushushanya neza gukomera gupima kugirango ugerageze gukomera kw'ibitambo. Leeb tester ikemura iki kibazo, ariko birakenewe kwitondera hejuru kurangiza akazi mugihe cyo gukoresha tester dester. Leeb Hardness Testers afite ibisabwa kugirango ugire ubuso bwubuso bwakazi.
Brinell Hardness Tester
Brinell Hardness Ikizamini kigomba gukoreshwa mugupima gukomera kwibikonyi. Kububiko bwicyuma hamwe nibinyampeke bibabaje ugereranije, ibizamini byingufu 3000kg hamwe na 10mm umupira 10mmmmm00 bigomba gukoreshwa bishoboka. Iyo ingano ya casting ari nto, rockwell gukomera gupima nayo irashobora gukoreshwa.
Ibikoresho byo mu ibyuma mubisanzwe bifite imiterere iringaniye, ingano nini, kandi zirimo karubone nyinshi, silicon nubundi ntamwambuzi kuruta ibyuma, kandi ubukana buzatandukana mubice bito cyangwa kumanota atandukanye. Indenter ya Brinell Hardness ifite ubunini bunini hamwe n'ahantu hanini indentation, kandi irashobora gupima impuzandengo y'agaciro k'ibikoresho biri murwego runaka. Kubwibyo, testers ikomeye ya brunell ifite ikizamini cyo hejuru kandi itana rito ryindangagaciro zikomeye. Agaciro gakomeye gasuzuguritse ni uhagarariye ubukana nyabwo bwumurimo. Kubwibyo, testerness ya brunell ikoreshwa cyane munganda zashizwe.
Gukomera
Urutare rukomeye rwagati narwo rusanzwe rukoreshwa mugupima icyuma. Kubikorwa birimo ibinyampeke byiza, niba nta gace gahagije kubizamini bya Brinell bigoye, ikizamini gikomeye cya Rockwell nacyo gishobora gukorwa. Kuberako paarlitike yoroshye yicyuma, gukonjesha ibihingwa byicyuma nibiti bya sb cyangwa hrb cyangwa HRC birashobora gukoreshwa. Niba ibikoresho bitari byiza, ibyasomwe byinshi bigomba gupimwa hamwe nibisanzwe bigomba gufatwa.
Inkombe
Mu manza ku giti cye, ku bigo bimwe na bimwe bifite imiterere minini, ntibyemewe guca icyitegererezo, kandi nticyemewe gutera izindi kizamini cyo kwipimisha gukomeye. Muri iki gihe, kwipimisha gukomera bizahura ningorane. Kuri uru rubanza, uburyo busanzwe nukugerageza gukomera hamwe ninkomoko yimukanwa hejuru yubuso bworoshye nyuma yo gutara. Kurugero, murwego rwumuzingo rwakoreshejwe cyane mu nganda za Metallurgive, hateganijwe ko ikizamini cyo gukomera ku nkombe bigomba gukoreshwa mu kugerageza gukomera.
