Ziziphi iingenelo zokucima izixhobo ezikhawulezayo zokucima izixhobo ngokwayo

Ukusetyenziswa kokucima i-high-frequency quenching iye yahlala kwishishini lesinyithi ixesha elide, ngokuthe ngcembe ithatha indawo yezixhobo zonyango lobushushu bendabuko, kunye nophuhliso oluqhubekayo lwezobuchwepheshe kwinkqubo yesinyithi yokuphucula ukusebenza kakuhle kwe-workpiece. Iindidi ezimbini zezixhobo zokucima amaza aphakathi, afana nokucima i-high-frequency quenching, zineenzuzo ezifanayo zobuchwepheshe, kodwa izixhobo ezahlukeneyo zokucima zikhethwa ngokweemfuno ezahlukeneyo zobuchwepheshe. Namhlanje, makhe sijonge kwiingenelo zokucima izixhobo zokucima isantya esiphezulu.

Ukucima i-high-frequency quenching ikakhulu isebenzisa umgaqo wokungeniswa kwe-electromagnetic, kwaye i-current induced eveliswayo inokuqhuba uthotho lokufudumeza, unyango lobushushu kunye nezinye iinkqubo kwindawo yokusebenza. Emva koko ineempawu kunye neenzuzo ezingenayo izixhobo eziqhelekileyo. Iinzuzo eziphambili ezibalaseleyo zezi:

1. Umphezulu we-workpiece awulula ukuba ube ne-oxidized. Ngenxa yokufudumala, i-workpiece idibanisa lula ne-oksijini, kwaye umphezulu we-oxidized, oya kuchaphazela umphumo wokufudumala we-workpiece. Endaweni yoko, inkqubo yokucima i-high-frequency ayibangeli i-oxidation egqithisileyo, kodwa isantya sokufudumala se-workpiece sikwakhawuleza, okuphucula ukusebenza kakuhle, kwaye i-workpiece ngokwayo ayifane ikhubazeke.

2. Umgangatho womgangatho owenziwe lukhuni we-high-frequency quenching workpiece ungaphakathi kwe-1-1.5mm, engafaniyo ne-intermediate frequency quenching. Ubunzulu boluhlu oluqinileyo lwe-intermediate frequency quenching inokufikelela ngaphakathi kwe-1-5mm, ngoko ke ukucinywa kwamaxesha aphakathi Kusetyenziswa xa ukucima i-high-frequency quenching ayikwazi ukuhlangabezana neemfuno zenkqubo. Kakade ke, ukuba yi-workpiece enomaleko oqina nzulu, sisebenzisa inkqubo yokucima amandla-frequency.

3. Indlela yokufudumala yesixhobo i-non-contact-heater, enokuthi ifudumale ngokukhawuleza i-workpiece ekhubazekileyo yesibini.

4. Inkqubo yokucima i-workpiece inokulawulwa ngokuzenzekelayo, kwaye inokuxhotyiswa ngesixhobo somshini wokucima ukufezekisa ukucima okuqhubekayo, ukucinywa kwamacandelo kunye nokuskena okulandelayo. Le ndlela ifaneleke kakhulu kwezinye iindawo zokusebenza ezineemfuno ezingqongqo.

5. Ukusebenza kwenkqubo yokushisa ukushisa kwezixhobo zokucima i-frequency ephezulu kulula kakhulu kwaye kuphantsi kweendleko.
