1. Zaɓi sigogin geometric na kayan aiki
A lokacin da maching bakin karfe, da geometry na yankan yankan kayan aiki ya kamata a yi la'akari da tsarin kayan aiki da kusurwar rake kusurwa da kusurwa ta baya. Lokacin zabar kusurwar rake, dalilai kamar su pandarfin hoto, kasancewar ko rashin chamfering da ƙwararrun kusurwa mai kyau da mara kyau da mara kyau. Ko da kuwa dole ne a yi amfani da kayan aiki mafi girma a lokacin da machining bakin karfe. Yana kara kusurwa na kayan aiki na iya rage juriya da aka samu a lokacin clo pl yankding da shafe. Zabi na kusurwar sharetar ba mai tsananin ƙarfi ba ne, amma bai kamata ya yi ƙarami ba. Idan kusurwar share fage tana da karami, zai haifar da mummunan tashin hankali tare da farfajiya na kayan aiki, yana bunkasa m da sauri kayan aiki suna suttura kayan aiki. Kuma saboda gogayya mai karfi, sakamakon hardening na farfajiyar bakin karfe yana inganta; Kada a rage yawan kayan aiki da yawa, wanda ya yi yawa, saboda haka an rage kusurwar kayan aikin, kuma suturar kayan da aka yankewa. Gabaɗaya, ya kamata a kusantar fitinar da ta dace fiye da yadda ake aiwatar da ƙarfe na yau da kullun.
Zabi na kusurwa rake kusurwa daga yanayin yankan zafi da kuma zafin rana, ƙara yawan rake da ya yi yawa, da kuma zafin jiki na da akasin haka. Daukaka. Rage rake na rake zai iya inganta yanayin zafin downration kai, da kuma yawan zafin jiki na iya raguwa, amma idan zafin rake zai zama mai mahimmanci, amma da zafin rana ya haifar da watsawa. Gwaji yana nuna cewa kusurwar rake = 15 ° -20 ° ya fi dacewa.
Lokacin zaɓi zaɓi na share fage don mamariya mama, ana buƙatar ƙarfin ƙarfi na ƙarfi na kayan yankan ana buƙatar zama babba, don haka ya kamata a zaɓi ƙaramin kusurwa; A lokacin gama, suturar kayan aiki galibi tana faruwa a yankin yankan da kuma flank farfajiya. Bakin karfe, kayan da ke iya yiwuwa a kan aiki hardening, yana da mafi yawan tasiri a kan ingancin yanayin da kayan aikin da aka haifar ta hanyar tashin saman flank. Ya kamata a kusantar agaji mai ma'ana ta dace da ita: don bakin karfe bakin karfe (a ƙasa 185hb), faɗuwar uwa na iya zama 6 ° - -8 °; Don aiki ta hanyar nuna bakin karfe bakin karfe (sama da 250hb), kusurwar sharewar shine 6 ° -8 °; Don Martensitic bakin karfe (a kasa 250hb), kusurwar share fage tana 6 ° -10 °.
Zabi na Haske na ɗaukakakken girman da shugabanci na Wurin Neman Wurin Hutu Kayyade jagorancin guntu ya kwarara. Zaɓin mai dacewa da kusurwar wucin gadi ls yawanci -10 ° -20 °. Ya kamata a yi amfani da kayan aikin ƙwallon ƙafa lokacin da ya kamata a yi amfani da kayan aikin waje lokacin da ƙananan da'irar waje, ramuka mai kyau, da jirage mai kyau: ls45 ° -755 ° ya kamata a yi amfani da shi.
2. Zabi kayan kayan aiki
A lokacin da Gudanar da bakin karfe, mai hana shi ya sami isasshen ƙarfin ƙarfi da ƙiyayya saboda ƙarfin yankan yankan don gujewa tattaunawar magana da nakasa a lokacin yankan. Wannan yana buƙatar zaɓin manyan yanki mai dacewa-sashi na mai riƙe da kayan aiki, da kuma amfani da kayan aiki mai ƙarfi don ƙirƙirar mai riƙe da kayan aiki, kamar amfani da quenched da 50 karfe.
Bukatun don yankan kayan aiki lokacin da aiki bakin karfe, ana buƙatar ɓangaren yankan kayan aiki don samun babban abin juriya da kuma kula da yankan yanayin a cikin zafin jiki sosai. A halin yanzu kayan aikin da ake amfani dasu sune: babban ƙarfe mai sauri da carbide. Saboda tsananin zafin karfe na iya kiyaye cikawar da ke ƙasa 600 ° C, bai dace da yankan yanki ba, amma ya dace da sarrafa bakin karfe a ƙananan gudu. Saboda carbide na Carbide yana da mafi kyawun head da headsa da kuma sanadin juriya da kayan carbide sun fi dacewa da yankan bakin karfe.
Cemented Carbide ya kasu kashi biyu: Taggetten-cobalt Aloy (yg) da Titsten-cobalt-titanium Aliloy (YT). Allos-cobalt Alloys suna da kyau tauri. Kayan aikin kayan aikin da aka yi na iya amfani da babban kusurwa mafi girma da kuma gefen shaiper don niƙa. Kwallan suna da sauƙin lalacewa yayin aikin yankan, kuma yankan shine brisk. Kips ba sauki a tsaya ga kayan aiki. A wannan yanayin, ya fi dacewa a aiwatar da bakin karfe tare da tungsten-cobalt poyoy. Musamman ma a cikin mamariya mai wuya da yankan tsinkaye tare da manyan rawar jiki, ya kamata a yi amfani da ruwan gwal-Cobal. Ba shi da wuya da kuma title da Torgen-cobalt-titanium Dayoy, ba mai sauƙi ga kai, kuma mai sauƙin guntu ba. Tongent-cobalt-titanium alloy yana da kyau ja wuya kuma ya fi abin da ke jurewa fiye da Taggerten-compalt na tasiri da rawar jiki don bakin aiki don bakin karfe mai kyau.
Ayyukan yankan kayan kayan aiki yana da alaƙa da karkara da yawan kayan aiki, da kuma masana'antun kayan aikin ya shafi masana'antu da ingancin kayan aiki da kanta. Yana da kyau a zabi kayan kayan aiki tare da babban ƙarfi, tsayayyen tsayayya da ƙarfi, saboda haka a cikin bakin karfe da ti a cikin baƙin ƙarfe bakin ƙarfe, kamar yadda ba a yin amfani da YT. Chops na iya ɗaukar ti cikin sauƙi a cikin alloy, wanda ke inganta haɓakar kayan aiki. Samar da aikin ya nuna cewa yin amfani da YG532, YG83 da YW2 maki uku na kayan don aiwatar da bakin karfe yana da sakamako mai kyau
3. Zabi na adadin yankan
Domin kashe ƙarar gefen da aka gina da kuma inganta ingancin kayan aikin carbide, lokacin da aka yanka shi da yawa shine f = 0.15- lahira.
4. Bukatar don farfajiya na yankan yankan kayan aiki
Inganta ƙarshen ƙarshen yankan kayan aiki na iya rage juriya lokacin da kwakwalwan kwakwalwan kwamfuta ke curled da haɓaka ƙarfin kayan aiki. Idan aka kwatanta da sarrafa talon na carbon na talakawa, lokacin da yake sarrafa bakin karfe, ya kamata adadin yankan da ya rage ya kamata a rage don rage jinkirin kayan aiki. A lokaci guda, sanyaya da ya dace da ruwa ya kamata a zaɓi don rage zafin rana da kuma rage karfi lokacin yankan, kuma don tsawaita rayuwar sabis ɗin.
