Bayan ɓangarorin masu taurarewar shigar sun kammala aikin kashewa, wadanne abubuwa ne ake duba gabaɗaya?
(1) ingancin bayyanar
Ingantacciyar yanayin da aka kashe na sassan sassan ba za su sami lahani irin su fusion, tsagewa, da dai sauransu. Filayen da aka saba kashewa ba shi da fari da baki (oxidized). Farin launin toka gabaɗaya yana nuna cewa zafin zafin ya yi yawa; duk baki ko shudi a saman gabaɗaya yana nuna cewa zafin zafin jiki bai isa ba. Ana iya samun narkewar gida da tsage-tsage na fili, dusar ƙanƙara, da sasanninta yayin dubawa na gani. Adadin duban bayyanar da sassan da aka samar a cikin ƙananan batches da batches shine 100%.
(2) Tauri
Ana iya amfani da gwajin taurin Rockwell don dubawa bazuwar. Ana ƙididdige ƙimar ƙima bisa mahimmancin sassa da kwanciyar hankali tsari, gabaɗaya 3% zuwa 10%, ƙari ta hanyar binciken fayil ko binciken fayil 100%. Yayin binciken fayil, yana da kyau mai duba ya shirya daidaitattun tubalan taurin wuya daban-daban don kwatantawa, don haɓaka daidaiton binciken fayil. A cikin kera na’ura mai sarrafa kansa, mafi haɓaka hanyar bincika taurin ta ɗauki eddy current tester da sauran layukan haɗin gwiwa don bincika yanki guda.
(3) Wuri mai kauri
Don sassan da aka kashe, ya zama dole don duba girman da matsayi na yankin da aka kashe. Ƙananan samar da tsari sau da yawa yana amfani da mai mulki ko caliper don aunawa, kuma ana iya amfani da acid mai ƙarfi don lalata saman da ya mutu don sa ya zama fari mai taurin wuri don dubawa. Ana amfani da hanyar etching sau da yawa don gwajin daidaitawa. A cikin samar da jama’a, idan inductor ko injin sarrafa kashewa ya kasance abin dogaro, gabaɗaya kawai bazuwar dubawa ne kawai, kuma ƙimar samfurin shine 1% zuwa 3%.
(4) Zurfin taurin Layer
A halin yanzu ana bincika zurfin daɗaɗɗen daɗaɗɗen tauraro ta hanyar yanke sassa masu tauri don auna zurfin daɗaɗɗen. Ya zuwa yanzu, an yi amfani da hanyar metallographic a baya don auna zurfin daɗaɗɗen Layer a baya, kuma GB 5617-85 za a aiwatar da shi nan gaba don sanin zurfinsa ta hanyar auna taurin sashe na Layer. Binciken zurfin bincike na Layer mai tauri yana buƙatar lalacewa ga sassan. Don haka, ban da sassa na musamman da ƙa’idodi na musamman, bazuwar dubawa gabaɗaya ana amfani da su. Ana iya bincika manyan sikelin samar da ƙananan sassa don yanki ɗaya a kowane lokaci ko yanki ɗaya don kowane ƙaramin adadin kayan aikin da aka samar, kuma yanki ɗaya na manyan sassa ana iya bincika tabo kowane wata. Lokacin amfani da na’urorin gwaji marasa lalacewa, ana iya ƙara ƙimar samfurin, har ma 100% ana iya amfani da su. Misali, idan saman kayan aikin ya ba da damar gwajin taurin Leeb ya shiga ciki, to ana iya duba shi gaba-da-gaba tare da majinjin taurin Leeb.
(5) Nakasu da juyewa
Ana amfani da nakasawa da jujjuyawa musamman don duba sassan ramin. Gabaɗaya, ana amfani da firam na tsakiya da alamar bugun kira don auna bambancin juyawa ko karkatar da sassan bayan kashewa. Bambancin pendulum ya bambanta bisa ga tsayi da rabon sashin. Za a iya daidaita sashin da aka taurare shigar da shi, kuma juyowar sa na iya zama dan girma. Gabaɗaya, bambancin pendulum da aka yarda yana da alaƙa da adadin niƙa bayan quenching. Karamin adadin niƙa, ƙarami da izinin pendulum bambanci. A diamita nika izinin general shaft sassa yawanci 0.4 ~ 1mm. Bambancin pendulum bayan an ba da izinin daidaita sassan shine 0.15 ~ 0.3mm.
(6) Tsage
Abubuwan da suka fi mahimmanci suna buƙatar dubawa ta hanyar binciken barbashi na maganadisu bayan sun mutu, kuma masana’antu masu kayan aiki mafi kyau sun yi amfani da phosphor don nuna fasa. Sassan da aka bincika ta hanyar maganadisu yakamata a lalata su kafin a tura su zuwa tsari na gaba.
