Kodi mukudziwa mawu awa: Helix angle, point angle, main cutting edge, mbiri ya chitoliro?Ngati sichoncho, muyenera kupitiriza kuwerenga.Tiyankha mafunso ngati awa: Kodi gawo lachiwiri ndi chiyani?Kodi ngodya ya helix ndi chiyani?Kodi zimakhudza bwanji kugwiritsa ntchito pulogalamuyo?
Chifukwa chiyani kuli kofunika kudziwa zinthu izi: Zida zosiyanasiyana zimayika zofuna zosiyanasiyana pa chida.Pachifukwa ichi, kusankha kwa kubowola kopindika ndi kapangidwe koyenera ndikofunikira kwambiri pakubowola.
Tiyeni tiwone zinthu zisanu ndi zitatu zofunika kwambiri pakubowola kopindika: ngodya ya nsonga, m'mphepete mwa nsonga, m'mphepete mwa chisel, kudula nsonga ndi nsonga kupatulira, mbiri ya chitoliro, core, secondary cutting edge, ndi helix angle.
Kuti tikwaniritse ntchito yabwino yodula muzinthu zosiyanasiyana, zinthu zonse zisanu ndi zitatu ziyenera kugwirizana.
Kuti tichite izi, titha kufananiza mitundu itatu yamitundu yosiyanasiyana:
- Kubowola mokhotakhota DIN 338, HSS-E
- Zopotoza kubowola DIN 338 , HSSE-Co M35
- Kupotoza kubowola DIN 338, HSS 4341
Ma point angle
Mbali ya nsonga ili pamutu wa kubowola kopindika.Ngodya imayesedwa pakati pa mbali ziwiri zazikulu zodula pamwamba.A point angle ndiyofunika kuti pakati popotoza kubowola muzinthu.
Pang'ono pang'ono mbali ya mfundo, m'pamenenso kuika pakati pa zinthuzo kumakhala kosavuta.Izi zimachepetsanso chiopsezo choterereka pamalo opindika.
Kukula kwa ngodya ya nsonga, kumachepetsa nthawi yogunda.Komabe, kupanikizika kwapamwamba kumafunika ndipo kuyika pakati pazinthuzo kumakhala kovuta.
Maonekedwe a geometrically, ngodya yaying'ono imatanthawuza mbali zazikulu zazitali, pomwe mbali yayikulu imatanthawuza mbali zazikulu zazifupi.
Main kudula m'mphepete
Mphepete zazikulu zodula zimatenga njira yeniyeni yobowola.Mphepete zazitali zimakhala ndi ntchito yodula kwambiri poyerekeza ndi m'mphepete mwachidule, ngakhale kusiyana kwake kuli kochepa kwambiri.
Kubowola kopindika nthawi zonse kumakhala ndi mbali ziwiri zazikulu zodulira zolumikizidwa ndi m'mphepete mwa chisel.
Dulani m'mphepete mwa chisel
Mphepete ya chisel yodulidwa ili pakati pa nsonga ya kubowola ndipo ilibe zotsatira zodula.Komabe, ndikofunikira pakumanga kupotoza kubowola, chifukwa kumalumikiza mbali ziwiri zazikulu zodulira.
Mphepete ya chisel yodulidwa imakhala ndi udindo wolowa m'zinthuzo ndipo imayambitsa kupanikizika ndi kukangana pazinthuzo.Zinthu izi, zomwe sizili bwino pakubowola, zimapangitsa kuti kutentha kuchuluke komanso kugwiritsa ntchito mphamvu zambiri.
Komabe, zinthuzi zimatha kuchepetsedwa ndi zomwe zimatchedwa "kuwonda".
Kudula nsonga ndi nsonga zapang'onopang'ono
Kupatulira kwa mfundo kumachepetsa m'mphepete mwa chisel chodulidwa pamwamba pa kubowola.Kupatulirako kumabweretsa kuchepa kwakukulu kwa mphamvu zolimbana ndi zinthuzo ndipo motero kuchepetsa mphamvu yofunikira ya chakudya.
Izi zikutanthauza kuti kupatulira ndiye chinthu chofunikira kwambiri pakuyika zinthuzo.Imawonjezera kuthamanga.
Mitundu yosiyanasiyana ya thinnings imayikidwa mu mawonekedwe a DIN 1412.Maonekedwe odziwika kwambiri ndi helical point (mawonekedwe N) ndi gawo logawanika (mawonekedwe C).
Mbiri ya chitoliro (mbiri ya groove)
Chifukwa cha ntchito yake ngati kanjira, mbiri ya chitoliro imalimbikitsa kuyamwa kwa chip ndikuchotsa.
Kukula kwa groove kumapangitsa kuyamwa kwa chip ndikuchotsa bwino.
Kuchotsa bwino kwa chip kumatanthauza kukula kwa kutentha kwakukulu, komwe kungayambitse kutsekeka komanso kusweka kwa kubowola kopindika.
Mawonekedwe a groove otakataka ndi athyathyathya, ma groove owonda ndi ozama.Kuzama kwa mbiri ya groove kumatsimikizira makulidwe a pobowola pachimake.Mawonekedwe a Flat groove amalola mainchesi akulu (wandiweyani).Mbiri yakuya yakuya imalola ma diameter ang'onoang'ono (oonda).
Kwambiri
Makulidwe apakati ndiyeso yodziwira kukhazikika kwa kubowola kopindika.
Zokhotakhota zokhala ndi mainchesi akulu (zokhuthala) zimakhala zokhazikika kwambiri motero ndizoyenera ma torque apamwamba komanso zida zolimba.Amakhalanso oyenera kugwiritsidwa ntchito pobowola m'manja chifukwa amalimbana ndi kugwedezeka komanso mphamvu zam'mbali.
Pofuna kuthandizira kuchotsedwa kwa tchipisi pa poyambira, makulidwe apakati amawonjezeka kuchokera ku nsonga ya kubowola kupita ku shank.
Ma chamfers otsogolera ndi m'mphepete mwachiwiri
Zitoliro ziwirizi zili pa zitoliro.Ma chamfers akuthwa pansi amagwiranso ntchito m'mbali mwa borehole ndikuthandizira chitsogozo cha kubowola kobowola.Ubwino wa makoma a borehole amatengeranso katundu wa kalozera.
Mphepete mwachiwiri imapanga kusintha kuchokera ku chamfers kupita ku groove profile.Imamasula ndi kudula tchipisi tomwe tamamatira ku zinthuzo.
Kutalika kwa ma chamfers owongolera ndi nsonga zachiwiri zodulira zimadalira kwambiri mbali ya helix.
Helix angle (ngodya yozungulira)
Chofunikira pakubowola kopindika ndi ngodya ya helix (makona ozungulira).Zimatsimikizira njira yopangira chip.
Ma angles akuluakulu a helix amapereka kuchotsa kothandiza kwa zipangizo zofewa, zotalika.Ma angles ang'onoang'ono a helix, kumbali ina, amagwiritsidwa ntchito pazinthu zolimba, zofupikitsa.
Zokhotakhota zomwe zimakhala ndi ngodya yaying'ono ya helix (10 ° - 19 °) zimakhala ndi zozungulira zazitali.Mobwerezabwereza, kupotoza kubowola ndi ngodya yayikulu ya helix (27 ° - 45 °) kumakhala ndi rammed (yaifupi) yozungulira.Zokhotakhota zozungulira zozungulira zozungulira zimakhala ndi ngodya ya helix ya 19 ° - 40 °.
Ntchito zamakhalidwe pakugwiritsa ntchito
Poyamba, nkhani ya ma twist drills ikuwoneka ngati yovuta kwambiri.Inde, pali zigawo zambiri ndi mawonekedwe omwe amasiyanitsa kubowola kokhota.Komabe, makhalidwe ambiri amadalirana.
Kuti mupeze kubowola koyenera, mutha kudziwongolera ku ntchito yanu mu sitepe yoyamba.Buku la DIN la zobowolera ndi zowerengera limatanthauzira, pansi pa DIN 1836, kugawidwa kwamagulu ogwiritsira ntchito mu mitundu itatu N, H, ndi W:
Masiku ano simudzangopeza mitundu itatu iyi ya N, H, ndi W pamsika, chifukwa pakapita nthawi, mitunduyi yakonzedwa mosiyanasiyana kuti ikwaniritse zokhotakhota za ntchito zapadera.Chifukwa chake, mafomu osakanizidwa apangidwa omwe machitidwe awo amatchulira sakhala ovomerezeka mu bukhu la DIN.Ku MSK simupeza mtundu wa N wokha komanso mitundu ya UNI, UTL kapena VA.
Mapeto ndi chidule
Tsopano mukudziwa zomwe zimagwira pobowola zomwe zimakhudza pakubowola.Gome ili m'munsili limakupatsani chithunzithunzi cha zinthu zofunika kwambiri pazantchito zina.
| Ntchito | Mawonekedwe |
|---|---|
| Kudula magwiridwe | Main kudula m'mphepete Mphepete zazikulu zodula zimatenga njira yeniyeni yobowola. |
| Moyo wothandizira | Mbiri ya chitoliro (mbiri ya groove) Mbiri ya chitoliro chomwe chimagwiritsidwa ntchito ngati kanjira kamene chimayang'anira kuyamwa ndi kuchotsedwa kwa chip, chifukwa chake, ndichinthu chofunikira kwambiri pa moyo wautumiki wa makina opotoka. |
| Kugwiritsa ntchito | Ngolo ya Point & Helix angle (ngodya yozungulira) Makona a mfundo ndi ngodya ya helix ndizofunikira kwambiri pakugwiritsa ntchito pazinthu zolimba kapena zofewa. |
| Pakati | Kudula nsonga ndi nsonga zapang'onopang'ono Kudulira nsonga ndi kupendekera nsonga ndi zinthu zofunika kwambiri pakuyika pakati pa zinthuzo. Pakupatulira m'mphepete mwa chisel wodulidwa amachepetsedwa momwe angathere. |
| Kulondola kwa concentricity | Ma chamfers otsogolera ndi m'mphepete mwachiwiri Ma chamfers otsogolera ndi m'mphepete mwachiwiri amakhudza kulondola kwa concentricity kwa kubowola kopindika komanso mtundu wa dzenje lobowola. |
| Kukhazikika | Kwambiri Makulidwe apakati ndiyeso yomwe imatsimikizira kukhazikika kwa kubowola kopindika. |
Kwenikweni, mutha kudziwa momwe mungagwiritsire ntchito komanso zinthu zomwe mukufuna kuzolowera.
Yang'anani momwe ma twist drills amaperekedwa ndikufananiza mawonekedwe ndi ntchito zomwe mukufuna kuti zinthu zanu zibowoledwe.
