CrWMn intsimbi eshushu eqengqelekayo imivalo engqukuva

I-CrWMn die ipleyiti yentsimbi sisixhobo sentsimbi, i-oyile yokucima i-deformation ephantsi ebandayo esebenzayo die steel.Intsimbi yokunxiba, ngenxa yokujoyina iqhezu lobunzima be-1.20% ~ 1.60% ye-tungsten, ifom ye-carbides ngoko emva kokucima kunye nobushushu obuphantsi ukuba babe ⼀ubunzima kunye i-abrasion resistance.I-Tungsten inceda ukugcina iinkozo ezicolekileyo ekubeni zenze intsimbi ibelula ngakumbi.Intsimbi iyachukumiseka ekwenzeni ikhabhoni, nto leyo enokubangela ukuba iblade ihambe.Nangona amandla, ukuqina kunye nokuqina kwentsimbi kuphezulu kunoko kwentsimbi yekhabhoni, ineziphene ezifana nokuqhekeka ngokulula kunye nokuqhekeka nokusila ngenxa yokwahlulwa kwe-carbide. Ukucinywa kuthande ukuba yintsimbi ye-carbon, kunye noluhlu lwesicelo luyancitshiswa.Ukuqina kunye nokumelana nokukrala kwentsimbi kunye nokuqina kwentsimbi yechromium kunye ne-chromium silicon emva kwentsimbi. Ukucima kulungile, kwaye ukuqina kulungile.
I-CrWMn isetyenziselwa ikakhulu isinyithi sesixhobo sekhabhoni ayinakuhlangabezana neemfuno zecandelo elikhulu lomnqamlezo, imilo entsonkothileyo yeenxalenye zokufa, ifuna ukuguqulwa okuncinci kokucima.
1) Olu hlobo lwentsimbi lusetyenziswa kakhulu ekuqhubeni intsimbi ecekethekileyo, isinyithi esingenawo intsimbi, izinto ezisisiseko zomthwalo okhanyayo kunye nemilo entsonkothileyo yokucofa isitampu esibandayo, ngakumbi kwimimandla yewotshi, isixhobo, into yokudlala kunye nemveliso yemveliso, njl.njl. Ukubiyela ipleyiti yentsimbi ye-austenite, ishidi lentsimbi ye-silicon kunye nepleyiti yentsimbi ephezulu ayifanelekanga.

2) ubukhulu bentsimbi bunokusetyenziselwa ukwenza izinto < 1 mm ze-blanking die complex shaped punch, i-concave die, i-set piece, kunye ne-intensive ⼀ imicu yomzobo onzulu uyafa. Imveliso yePunch yacebisa i-58 ukuya kwi-62 HRC ubulukhuni, kunye nemveliso ye-concave mold yacebisa ukuba ubulukhuni 60 ~ 64 HRC.

I-3) Isetyenziselwa ukufakwa kwe-punch die kunye nokumelana okuphezulu kunye nokuma okuyinkimbinkimbi ekugobeni ukufa. Ubunzima bokufa kwe-punch bunconywa ukuba bube yi-58 ~ 62HRC kunye ne-60-64hrc kucetyiswa ukuba ibe yi-60-64hrc xa usenza i-punch die.

I-4) I-convex die kunye ne-concave die for extrusion ebandayo ifa ye-aluminium parts.Ubulukhuni be-60 ~ 62HRC bunconywa kwi-punch die kunye ne-62 ~ 64HRC icetyiswa kwi-punch die.

I-5) I-extrusion ebandayo efayo yeengxenye zethusi kunye ne-extrusion ebandayo iyafa kwaye ifa ngamacandelo ensimbi, ubunzima obucetyiswayo yi-62-64hrc.

I-6) Emva kokuba yenziwe, ingasetyenziselwa ukwenza ii-molds ezinkulu ze-veneer ezisetyenziswa kumatshini woxinzelelo ongaphezu kwe-1mm, ngokuqhelekileyo ukwandisa ukuqina kwentsimbi ukuya kwi-50-55hrc. Nangona kunjalo, iziphene ezicacileyo zezicubu ezinje nge-banded carbide structure okanye i-chromatography yolwelo kufuneka zincitshiswe okanye zigwenywe.
