Bukatun dubawa masu inganci don giya bayan kashe ta high-frequency quenching kayan aiki

1. Ingancin farfajiya

Bai kamata a ƙone haƙoran ba, sannan a bincika ko akwai fasa a cikin hakora, duba 100% don ƙananan batches, da dubawa don manyan batches bisa ga ƙayyadaddun rabo.

2. Taurin ƙasa

100% dubawa don ƙananan batches, dubawa don manyan batches bisa ga ƙayyadaddun rabo, gabaɗaya yana buƙatar taurin 45-50HRC, kuma mafi girman ƙarfin 50-56HRC.

3. Kungiyar saman

Danna ZBJ36 009-88 don dubawa.

4. Ingantaccen zurfin Layer mai zurfi

Ta amfani da mai gwajin Vickers hardness, a kan giciye sashin haƙori a tsakiyar faɗin haƙori: auna daga farfajiya zuwa ciki, ƙarshen taurin Layer mai taurin kai shine kamar haka: iyakance taurin = 0.80*mafi ƙarancin ƙarfi zane.

5. Ƙarfafa rarraba Layer

1) Don giya tare da m <4mm, an yarda da cikakken taurin hakori, kuma kasan haƙorin yana da takamaiman Layer, gaba ɗaya 1.2mm.

2) Don kayan aiki tare da m = 4.5-6mm, lokacin amfani da dumama da kashe lokaci ɗaya, an yarda da tsayin haƙo 1/3 daga tushen haƙoran, kuma lokacin da aka ci gaba da kashe haƙora ɗaya, an yarda da girman haƙoran 1/4 mara nauyi.

3) Don giyar da ake kashewa a lokaci guda, zurfin tsakiyar tsayayyen sashi na sashin tsayi na kayan ya wuce 2/3 na zurfin ƙarshen taurare mai ƙarfi.

4) Lokacin da kayan cikin gida m <6mm, an ba da izinin Layer mai ƙarfi ya sami ɗan gangara.

5) Don shigar da manyan katako masu ƙarfi tare da m> 8mm, tsayin haƙoran haƙoran ya kamata ya zama sau 1.7 na modulus, kuma lokacin m <8mm, 2/3 tsayin haƙora yakamata a taurare.

Wannan labarin a taƙaice yana gabatar da abubuwan dubawa, abun ciki da buƙatun abubuwan da aka kashe na kayan aikin kashe wuta da yawa. Ina fatan zai taimaka wa aikin ku.
