Chitsogozo Chimodzi Chosankha Mtundu Woyenera
Sankhani kutengera miyeso isanu: kukula kwa ntchito, zipangizo, kuchuluka kwa kuuma, zofunikira molondola, ndi zochitika zogwiritsira ntchito. Palibe chifukwa chodera nkhawa, ingotsatirani malangizo ndipo mutha kupanga chisankho.
I. Choyamba, gawani m'magulu atatu akuluakulu a zoyesera kuuma
1. Rockwell Hardness Tester (HRC/HRB/HRA)
Yoyenera: chitsulo chozimitsidwa, chitsulo chofewa, mabearing, zida, zida zotenthetsera kutentha
Ubwino: kulondola kwambiri, komwe kumagwiritsidwa ntchito kwambiri mu miyezo ya dziko, zida zodziwika bwino zowunikira khalidwe la fakitale
Zoyipa: muyenera kutenga zitsanzo / mtundu wa desktop, zigawo zazikulu sizingasunthidwe kapena kuyesedwa pamalopo
Zoyezera:
HRC: chitsulo cholimba kwambiri (ma dies, zida, magiya)
HRB: mkuwa, aluminiyamu, chitsulo chotsika mpweya, chitsulo chofewa
2. Choyesera Kuuma kwa Brinell (HB)
Yoyenera: chitsulo chosungunuka, chitsulo chosungunuka, aluminiyamu, aloyi yamkuwa, zida zopangira zozungulira
Ubwino: kupindika kwakukulu, kolondola kwambiri pa zipangizo zokhala ndi mizere yolimba komanso zosafanana
Zoyipa: kupindika kwakukulu, kuwononga, kusagwira ntchito bwino, koyenera kufufuzidwa malo a labotale
3. Leeb Hardness Tester (yonyamulika ku HL kupita ku HRC/HB/HV)—YY251D Leeb Kuuma Tester
Yoyenera: zigawo zazikulu, kuyesa komwe kuli pamalopo, zigawo zomwe sizingachotsedwe, nkhungu zolemera, mipukutu, mivi
Ubwino: chogwiritsidwa ntchito m'manja komanso chonyamulika, chosawononga, palibe chifukwa chotengera zitsanzo, chingagwiritsidwe ntchito moyimirira, mopingasa, kapena pamwamba
Zoyipa: kulondola kochepa pang'ono kuposa kompyuta ya Rockwell, zolakwika zazikulu pazigawo zopyapyala komanso zazing'ono
II. Sankhani kutengera momwe ntchito ikuyendera (yothandiza kwambiri)
Chitsanzo 1: labotale ya workshop, kuyang'anira bwino zinthu zomwe zikubwera / kutentha, kulondola kwambiri kumafunika Sankhani choyesera kuuma kwa Rockwell pa desktop
Amakonda kwambiri mafakitale ogwiritsira ntchito zida wamba, opanga zida zoyeretsera, komanso okonza kutentha.
Chitsanzo chachiwiri: chitsulo chopangidwa ndi chitsulo, zinthu zopangidwa ndi chitsulo chopangidwa ...
Sankhani choyesera kuuma kwa Brinell
Chitsanzo 3: ziwalo zazikulu zomwe sizingasunthidwe, kuyesa komwe kuli pamalopo, ma molds / rolls / shafts akuluakulu Muyenera kusankha choyesera kuuma kwa Leeb chonyamulika
Chitsanzo 4: Zigawo zazing'ono, mapepala opyapyala, kuuma kwa pamwamba pa zigawo zosungunuka ndi zophikidwa ndi nitride Sankhani choyesera kuuma kwa Vickers (HV)
Yoyenera: mapepala opyapyala, m'mphepete mwa zida, zokutira, zigawo zolimba.
III. Sankhani kutengera makulidwe/kukula kwa workpiece
Zigawo zazikulu, zolemera, komanso zosasunthika → Leeb
Zitsanzo zokhazikika, zigawo zazing'ono, zitha kuyikidwa pa desktop → Rockwell
Zigawo zoonda < 3mm, zouma pamwamba → Vickers
Zopanda kanthu, zinthu zosafanana → Brinell
IV. Sankhani kutengera mulingo wouma
Zipangizo zofewa: aluminiyamu, mkuwa, chitsulo chopanda mpweya wambiri → HRB / HB
Kuuma kwapakati: chitsulo chozimitsidwa ndi chofewa, chitsulo chomangira → HRC / HB
Kuuma kwakukulu: ma dies ozimitsidwa, zida, mabearing → HRC / HV
Zigawo zoonda kwambiri / zigawo zopangidwa ndi carburized → HV Vickers
