Zaɓin Lathe Indexable Blade (CNC Blade)

Bayan samun zane na workpiece, da farko zaži ruwa mai ƙididdigewa tare da siffar da ta dace bisa ga buƙatun zane. Gabaɗaya, ana amfani da lathe ɗin don juya da'irar waje da rami na ciki, yanke da yanke tsagi, da juya zaren. An ƙayyade zaɓin ruwa bisa ga takamaiman yanayin fasahar sarrafawa. Gabaɗaya, ya kamata a zaɓi ruwan wukake masu girma dabam da ƙarin yankan gefuna akan ruwa iri ɗaya. Zaɓi girma mafi girma don m juyi da ƙarami girma don mai kyau da rabin kyau juyi. Dangane da buƙatun fasaha, muna ƙayyade sifar da ake buƙata, yanke tsayin gefen, baka mai kauri, kaurin ruwa, kusurwar baya da daidaiton ruwa.

 一. Zaɓi siffar ruwa 

1. The ruwa daga cikin m CircleS-siffa: hudu yankan gefuna, tare da gajeren yankan baki (koma zuwa guda ciki yankan da'irar diamita), high ƙarfi na kayan aiki tip, yafi amfani da 75 ° da 45 ° kayan aikin juya, da kuma amfani da aiki ta hanyar-rami a ciki rami kayan aikin.

T-siffa: uku yankan gefuna, dogon yankan gefen da ƙananan ƙarfi na tip. Ana amfani da ruwan wukake tare da kusurwar jujjuyawar taimako akan lathe gabaɗaya don inganta ƙarfin tip. Yafi amfani da 90 ° juya kayan aikin. Ana amfani da kayan aikin jujjuya ramin ciki don sarrafa ramukan makafi da ramukan mataki.

Siffar C: akwai kusurwoyi masu kaifi iri biyu. Ƙarfin tukwici biyu na kusurwar 100 ° mai kaifi yana da girma, gabaɗaya an yi shi zuwa kayan aikin juyawa 75 °, wanda ake amfani da shi don karkatar da da'irar waje da ƙarshen fuska. Ƙarfin gefuna biyu na kusurwar 80 ° mai kaifi yana da girma, wanda za'a iya amfani dashi don aiwatar da ƙarshen fuska ko cylindrical surface ba tare da canza kayan aiki ba. Ana amfani da kayan aikin jujjuya ramin ciki gabaɗaya don sarrafa ramin mataki.

R-siffa: zagaye gefen, amfani da machining musamman baka surface, high amfani kudi na ruwa, amma babban radial karfi.

W siffar: uku yankan gefuna da gajere, 80 ° kaifi kwana, high ƙarfi, yafi amfani da machining cylindrical surface da mataki surface a kan general lathe.

D-siffa: biyu yankan gefuna ne dogon, yankan gefen kusurwa ne 55 ° da ƙarfin yankan gefen ne low, wanda aka yafi amfani da profiling aiki. Lokacin yin kayan aiki na juyawa na 93 °, kusurwar yanke ba zai zama mafi girma fiye da 27 ° - 30 °; lokacin yin kayan aiki na juyawa na 62.5 °, kusurwar yankan ba zai zama mafi girma fiye da 57 ° - 60 ° ba, wanda za'a iya amfani dashi don rami na mataki da tsaftacewa mara tushe lokacin sarrafa rami na ciki.

Siffar V: yankan gefuna biyu da tsayi, 35 ° kaifi kwana, ƙarancin ƙarfi, ana amfani da su don bayanin martaba. Lokacin yin kayan aiki na juyawa na 93 °, kusurwar yankan ba zai fi 50 ° ba; lokacin yin kayan aiki na juyawa na 72.5 °, kusurwar yankan ba zai fi 70 ° ba; Lokacin yin 107.5 ° kayan aiki na juyawa, kusurwar yanke ba zai zama mafi girma fiye da 35 ° ba.

2. Yanke da tsaga ruwan wukake:

1) yankan ruwa:

A cikin lathe CNC, ana yawan amfani da yankan ruwa don danna siffar tsinke guntu kai tsaye. Yana iya sa kwakwalwan kwamfuta su ragu kuma su lalace a gefe, a yanka cikin sauƙi da dogaro. Bugu da ƙari, yana da babban kusurwar jujjuyawar gefe da kusurwar baya, ƙarancin yanke zafi, tsawon rayuwar sabis da farashi mafi girma.

2) tsagi ruwa: gabaɗaya, ana amfani da yankan ruwa don yanke tsagi mai zurfi, kuma ana amfani da ruwan kafa don yanke tsagi mara zurfi, kamar haka: tsagi na tsaye, lebur mai lanƙwasa, ruwan tsiri, matakin tsabtace baka mai tsagi. Waɗannan ruwan wukake suna da daidaitattun faɗin tsagi.

3. Zare: L-An fi amfani da ruwa mai siffa, wanda zai iya zama ƙasa kuma mai arha, amma ba zai iya yanke saman haƙori ba. Zaren tare da daidaitattun yankan yana buƙatar amfani da ruwa tare da niƙa mai kyau na bayanin martaba. Saboda zaren ciki da na waje suna da girman bayanan martaba daban-daban, an raba su zuwa wukake na ciki da na waje. An gyara sautin su kuma ana iya yanke shi daga kambi. A matsayin hanyar matsawa, ana iya raba shi zuwa nau'i biyu: daya shine ruwa mara rami, wanda aka manne ta danna sama. Lokacin sarrafa kayan tare da babban filastik, wannan ruwa yana buƙatar ƙara farantin baffle; ɗayan kuma itace mai ramin matsewa da guntu mai tsinkewa, wanda aka maƙe shi ta hanyar dunƙule plum tare da rami mai matsa lamba.

 二. Tsawon tsinke

Yanke tsayin gefen: za a zaɓa shi bisa ga daftarin baya. Gabaɗaya, tsayin ɓangarorin ɓangarorin ta hanyar tsagi zai zama ≥ 1.5 sau na daftarin baya, kuma tsayin yanke shingen rufaffiyar tsagi ya zama ≥ 2 sau na daftarin baya.

三. tip baka

Tukwici baka: idan dai an ba da izini ga rigidity don jujjuyawar juyi, za a iya amfani da radius mafi girma na tip baka gwargwadon yuwuwa, yayin da ƙarami radius gabaɗaya ana amfani dashi don jujjuyawa mai kyau. Koyaya, lokacin da aka ba da izinin tsauri, ya kamata kuma a zaɓi shi daga ƙimar mafi girma, kuma radius ɗin da'irar da'irar da aka saba amfani da ita shine 0.4; 0.8; 1.2; 2.4, da sauransu.

四. ruwa kauri

Kaurin ruwa: ƙa'idar zaɓi ita ce sanya ruwa ya sami isasshen ƙarfi don ɗaukar ƙarfin yanke, wanda yawanci ana zaɓa bisa ga ciyarwar baya da abinci. Misali, wasu igiyoyin yumbu suna buƙatar zaɓar ruwan wukake masu kauri.

 五. bayan kwana na ruwa

Wurin baya: wanda aka saba amfani dashi:

0 ° code n;

5 ° lambar B;

7 ° C;

11 ° kod P.

0 ° baya kwana ana amfani dashi gabaɗaya don jujjuyawar juzu'i da juzu'i, 5 °; 7 °; 11 °, ana amfani da shi gabaɗaya don kammalawa na gamawa, jujjuyawar ƙarewa, bayanin martaba da sarrafa ramukan ciki.

六. daidaiton ruwa

Blade daidaici: akwai nau'ikan madaidaicin 16 da jihar ta kayyade don ruwan wukake mai ƙima, daga cikinsu nau'ikan nau'ikan 6 sun dace da kayan aikin juyawa, lambar ita ce h, e, G, m, N, u, h shine mafi girma, u shine mafi ƙasƙanci, ana amfani da u don m da Semi gama machining na janar lathe, M ana amfani da CNC lathe ko m da ake amfani da GNC matakin da kuma G.

Bayan matakan da ke sama, mun ƙaddara ainihin irin nau'in ruwa ya kamata a yi amfani da shi. A mataki na gaba, muna buƙatar ƙara bincika samfuran lantarki na masu kera ruwa, sannan a ƙarshe ƙayyade nau'in ruwan da za a yi amfani da shi bisa ga kayan aiki da daidaiton da za a sarrafa.
