Kunezinkampani eziningi ezithengisa izivivinyo zokuqina kwe-Rockwell emakethe njengamanje. Ungayikhetha kanjani imishini efanele? Noma kunalokho, sikwenza kanjani ukukhetha okufanele ngamamodeli amaningi kangaka atholakalayo?
Lo mbuzo uvame ukubakhathaza abathengi, njengoba uhla olubanzi lwamamodeli kanye namanani ahlukahlukene kwenza kube nzima ukunquma. Ngezansi umhlahlandlela omfushane wokukusiza ukhethe isihloli sokuqina seRockwell esifanele.
Izihloli zokuqina zeRockwell ziyizinto ezisetshenziswa kakhulu ekuhlolweni kokuqina. Ngenxa yezinzuzo zazo ezifana nokusebenza okulula, isivinini sokuhlola esisheshayo, izidingo eziphansi zezinto zokusebenza, kanye nezidingo zamakhono amancane kubasebenzi, zisetshenziswa kabanzi ezimbonini zokwelapha ukushisa, ama-workshop, amanyuvesi, izikhungo zocwaningo, amasimu ezindiza njll.
1. Isimiso sabahloli bokuqina kweRockwell
Abahloli bobulukhuni baseRockwell basebenza ngesimiso sokulinganisa ukujula. Ukukhuluma nje: sebenzisa amanani ahlukene amandla kuma-indenter ahlukene, dala ama-indentations, bese ufunda ngokuqondile inani lobulukhuni.
2. Ukuhlukaniswa Kwabahloli Bokuqina Kwe-Rockwell
1) Kuhlukaniswe Ngesilinganiso
Abahloli bokuqina beRockwell abajwayelekile: hlola izikali eziyi-15 ezihlanganisa i-HRA, i-HRB, kanye ne-HRC.
Abahloli bokuqina be-Rockwell abangaphezulu: hlola izikali eziyi-15 kufaka phakathi i-HR15N, i-HR30N, i-HR45N, i-HR15T, njll.
Abahloli bobulukhuni bePlastiki Rockwell: hlola izikali zepulasitiki ezifana ne-HRE, HRL, HRM, HRR, njll.
Abahloli bokuqina be-Rockwell abagcwele: bahlanganisa zonke izikali ze-Rockwell (ezijwayelekile, ezingaphelele, nezepulasitiki), zizonke izikali ezingama-30.
2) Kuhlukaniswe ngohlobo lomshini
Abahloli bobulukhuni bedeskithophu ye-Rockwell
Abahloli bokuqina beRockwell ephathekayo
3) Kuhlukaniswe ngohlobo lokubonisa
Uhlobo lwe-analog (ukufundwa kwedayela): umthwalo ngesandla, ukulayisha ngesandla, kanye nokufunda kwedayela.
Isibonisi sedijithali (i-LCD noma isikrini sokuthinta): umthwalo ozenzakalelayo, ukulayisha okuzenzakalelayo, kanye nesibonisi senani lobulukhuni okuzenzakalelayo.
4) Kuhlukaniswe ngeNdlela Yokusebenzisa Amandla
Isisindo somthwalo
Umthwalo wesenzwa esivaliwe/umthwalo weseli
5) Kuhlukaniswe ngesakhiwo somshini
Ukuphakamisa izikulufo
Uhlobo lwekhanda phezulu naphansi
6) Kuhlukaniswe ngokwezinga lokuzenzakalela
6.1) Isivivinyo Sokuqina Kwe-Rockwell Esenziwa Ngesandla
Amandla okuqala okuhlola alayishwa ngesandla; amandla amakhulu okuhlola alayishwa futhi alayishwe ngesandla.
Ukusebenza: ukuxhumana kwe-indenter nesampula, i-pointer enkulu ijika imibuthano emithathu egcwele, idonsa ngesandla isibambo sokulayisha ukuze isebenzise amandla, bese ucindezela isibambo ukuze ukhulule, funda inani le-pointer, isixazululo esingu-0.5HR.
6.2) Isivivinyo Sokuqina Kokuqina Kwe-Rockwell Kagesi
Amandla okuqala okuhlola alayisha ngesandla; amandla amakhulu okuhlola alayisha, ahlaliswe, futhi akhishwe ngokuzenzakalelayo (udinga ukucindezela inkinobho ethi “Layisha”; isikhathi sokuhlala singalungiseka)
Izinyathelo zokusebenza: ukuxhumana kwe-indenter nesampula, i-pointer enkulu ijika izindilinga ezintathu ezigcwele, cindezela inkinobho ethi “Layisha”, ulayishe ngokuzenzakalelayo, uhlale, bese ukhulula; funda inani le-pointer, isixazululo esingu-0.1HR.
6.3) Isibonisi Sedijithali se-Rockwell Hardness Tester: izinhlobo ezimbili
6.3.1) Amandla okuqala okuhlola alayisha ngesandla; amandla amakhulu okuhlola alayisha, ahlale, futhi akhulule ngokuzenzakalelayo.
Ukusebenza: ukuxhumana kwe-indenter nesampula, ukufinyelela kwebha yenqubekela phambili KULUNGILE, umthwalo ozenzakalelayo, ukuhlala, nokulayisha, inani lobulukhuni liboniswa ngokuzenzakalelayo, isixazululo esingu-0.1HR.
6.3.2) Amandla okuqala okuhlola alayisha ngokuzenzakalelayo; amandla amakhulu okuhlola alayisha, ahlale, futhi akhulule ngokuzenzakalelayo.
ukusebenza: uma ibanga phakathi kwe-indenter nesampula lingu-0.5mm, cindezela inkinobho ethi “Layisha”, ama-indenter awela ngokuzenzakalelayo, alayishe, ahlale, alayishe, ama-indenter aphakamisa ngokuzenzakalelayo, inani lobulukhuni liboniswa ngokuzenzakalelayo, isixazululo esingu-0.1HR.
6.4) Isivivinyo Sokuqina Kwe-Rockwell Esizenzakalelayo Ngokugcwele (ukubhekisela: “Isivivinyo Sokuqina Kwe-Rockwell Esizenzakalelayo Ngokugcwele – Qonda Ngomusho Owodwa”)
Izici: ukuphakamisa izikulufo okuzenzakalelayo, ukukhethwa kwamandla okuhlola okuzenzakalelayo, umthwalo wamandla okuqala nowokuhlola oyinhloko ozenzakalelayo, ukulayisha okuzenzakalelayo, kanye nokubonisa inani lokuqina okuzenzakalelayo.
Ukusebenza: ukusebenza kwenkinobho eyodwa, cindezela inkinobho yokuqala; ibhentshi lokusebenza liphakama ngokuzenzakalelayo, ngemva kokuba isampula ixhumane ne-indenter, ilayisha ngokuzenzakalelayo, ilayishe ngokuzenzakalelayo, inani lobulukhuni liboniswe ngokuzenzakalelayo.
(Ibhentshi lokusebenza liphakamisa ngokuzenzakalelayo ngaphandle kwemingcele yokuphakama, ngaphandle kokujikeleza ngesandla kwe-screw swing.)
7) Kuhlukaniswe Ngokwezifiso
Imishini ejwayelekile; imishini eyenziwe ngezifiso; abahloli bobulukhuni be-inthanethi, njll.
3. Abahloli bokuqina beRockwell bayahlukahluka ngentengo ngokuya ngokucushwa kwabo kanye nomsebenzi wabo. Ungayikhetha Kanjani I-Hardness Tester?
