Mndandanda: Chifukwa Chake Ma Drill Bits Amalephera | Nkhani 16
Mawu Ofunika: RPM yolakwika yobowola, liwiro la drill bit, HSS drill bit RPM, liwiro lodulira kubowola, liwiro la drill ndi feed, drill bit diameter ndi RPM, liwiro la drill steel stainless steel, feed per revolution, drill bit wear, drill bit breakage, stainless steel work hardening, chifukwa chake drill bits hazisagwire ntchito
Chobowola chingalephere msanga ngati liwiro lake silikugwirizana ndi kukula kwake, ntchito yake ndi chakudya chake. Kukhazikitsa kwa RPM kothandiza kuyenera kulumikizidwa ndi zonse zitatu. Kungotembenuza makina mwachangu, kapena pang'onopang'ono, sikutsimikizira dzenje labwino.
Nkhaniyi ikuyang'ana kwambiri pa ma drill a HSS omwe amagwiritsidwa ntchito mu chitsulo. HSS imatanthauza chitsulo chothamanga kwambiri. Ma verification omwe ali pansipa akufotokoza ubale; sankhani makonda opangira kuchokera ku deta ya drill yeniyeni ndi zinthu.
1 Mvetsetsani liwiro musanasankhe RPM
| Nthawi | Tanthauzo lake |
| Liwiro la spindle n mu RPM | Kodi drill imapanga ma revolution angati mphindi iliyonse? |
| Kudula liwiro Vc mu m/mph | Liwiro la m'mphepete mwa kudula pa m'mimba mwake wakunja kwa kubowola. |
| M'mimba mwake D mu mm | Gwiritsani ntchito kukula kwa kudula, osati kukula kwa shank komwe kwachepetsedwa. |
Pa RPM yomweyo, chobowola chachikulu chimakhala ndi liwiro lalikulu lodulira lakunja. Pa RPM 1,000, chobowola cha 10 mm chimayenda pafupifupi nthawi 3.3 kuposa liwiro lodulira la 3 mm. Izi ndi mitengo yowerengedwa, osati makonda olimbikitsidwa.
Chithunzi 1 RPM yomweyo, liwiro losiyana la kudula. Kuwerengedwa kuchokera ku Vc = πDn / 1000.
2 Kuthamanga kwambiri kungafupikitse nthawi yogwiritsira ntchito bowola
Chobowola chingataye m'mphepete mwake chisanasweke. Kuthamanga kwambiri komanso kusakwanira kwa chakudya kungafupikitse nthawi ya zida. Kuthamanga kwambiri kungawonongenso ngodya zakunja. Kutumiza koziziritsira ndi kusankha chobowola n'kofunikanso.
Mphepete yosweka ingafunike mphamvu zambiri kuti ipitirize kudula. Kupitiliza ntchito popanda kuyang'ana m'mphepete ndipo njirayi ingasinthe vuto la kusweka kukhala vuto losweka. Lembani momwe kubowola kunalepherera komanso komwe kuwonongeka kunayambira musanasankhe choti musinthe.
3 Kuchedwa sikwabwino nthawi zonse
Kuthamanga kwambiri komanso kosakwanira kwa kuboola kungayambitse kusweka. Mabowole ang'onoang'ono achitsulo chosapanga dzimbiri sayenera kuyendetsedwa okha pa RPM yotsika kwambiri.
Palinso vuto la chakudya. Pa makina omwe amasunga chakudya mu mm/min, kutsika kwa RPM kumawonjezera mtunda wopita patsogolo pa kuzungulira kulikonse pokhapokha ngati makonda a chakudya asinthanso. Chitsanzo chogwira ntchito paaZotsatirazi zikusonyeza chifukwa chake izi ndizofunikira.
Kusintha liwiro sikungakonze ntchito yotayirira, m'mphepete mwawonongeka kapena chitoliro chodzaza ndi tchipisi. Zinthu zimenezo zimafunika kuziyang'anira zokha.
4 Chitsulo chosapanga dzimbiri chimafunika kudula bwino
Zitsulo zosapanga dzimbiri za Austenitic monga 304 ndi 316 zimatha kulimba pobowola. Kulimba kwa ntchito kumatanthauza kulimba komwe kumachitika chifukwa cha kusintha kwa pulasitiki. Siziyenera kufotokozedwa ngati kutentha komwe kumapangitsa chitsulo kukhala cholimba.
Sungani chakudya choyenera ndipo pewani kukhala pansi kapena kukanda pamene chobowolera chikukhudzana ndi zinthuzo. Ma chips ayeneranso kutuluka m'bowo. Izi zimafuna m'mphepete mwake, chakudya choyenera komanso kuchotsa ma chips moyenera. Sizitanthauza kugwiritsa ntchito mphamvu zopanda malire.
Ngati chobowolera chikupitiriza kuzungulira pamalo omwewo popanda kupititsa patsogolo kapena kuchotsa zinthu, yang'anani momwe kudula kulili komanso momwe m'mphepete mwake mulili. Kupukuta mobwerezabwereza kungapangitse kudula kotsatira kukhala kovuta. Musayankhe mwa kuwonjezera mphamvu popanda kupeza chifukwa.
Kodi izi zikutanthauza chiyani m'machitidwe
Gwiritsani ntchito RPM ngati gawo limodzi la njira yobowolera. Onaninso liwiro la bowolera pamodzi ndi chakudya, choziziritsira ndi kuchotsa tchipisi. Bowolera lopangidwa bwino limafunikirabe mikhalidwe yoyenera yogwirira ntchito; vuto la kugwiritsa ntchito silichotsa vuto la kupanga.
5 Chizindikiro cha HSS cha chitsulo chosapanga dzimbiri
Chitsulo chosapanga dzimbiri chotchedwa HSS chomwe chimagwiritsidwa ntchito podula liwiro ndi mamita 30 mpaka 50 pamwamba pa mphindi, zomwe ndi 9.144 mpaka 15.24 m/min. Tebulo ili m'munsimu limasintha liwiro limenelo kukhala RPM. Gwiritsani ntchito kuti mumvetse momwe kukula kwake kumakhudzira liwiro, kenako yang'anani makonda a kubowola ndi zinthu zomwe zili mkati mwake.
| M'mimba mwake kubowola | Pa 9.144 m/mphindi | Pa 15.24 m/mphindi |
| 3 mm | 970 RPM | 1,617 RPM |
| 6 mm | 485 RPM | 809 RPM |
| 10 mm | 291 RPM | 485 RPM |
| 13 mm | 224 RPM | 373 RPM |
Gome 1 RPM yowerengedwa, yozunguliridwa kufika pa RPM yonse yapafupi. Kusintha: 1 ft = 0.3048 m.
Chithunzi 2 Kuthamanga komweko kwa kudula kumafuna RPM yotsika pamene kukula kwa dayamita kukukwera. Mzere wojambulidwa ndi mtundu wowerengera, osati malo ogwirira ntchito otetezeka omwe ayesedwa.
Iyi ndi njira yodziwika bwino yogwiritsira ntchito HSS. Sipereka malo apadera pa mtundu uliwonse wosapanga dzimbiri, kuuma, kuphimba kapena kubowola kwa cobalt HSS. Ma mtengo awa si malingaliro a Jiacheng M35 kapena M42.
Gwiritsani ntchito deta yeniyeni ya wopanga kubowola kaye. Yang'anani kuchuluka kwa zinthu ndi momwe zilili, kuya kwa dzenje, choziziritsira madzi ndi mphamvu ya makina. Musakopere tchati cha liwiro la carbide ku kubowola kwa HSS.
6 Yerekezerani RPM ndi chakudya
Kudyetsa pa kuzungulira fn ndi mtunda womwe bowolo limapita patsogolo nthawi imodzi, mu mm/rev. Liwiro la chakudya Vf ndi mtunda wopita patsogolo mu mphindi imodzi, mu mm/min. Ubale wawo ndi:
Vf= fnxn
Tiyerekeze kuti makinawo agwira liwiro la chakudya pa 60 mm/min. Kusintha RPM yokha kumabweretsa zotsatirazi. Ichi ndi chitsanzo cha masamu, osati malangizo obowola.
| Liwiro la spindle | Liwiro la chakudya | Chakudya pa kusintha kulikonse |
| 1,200 RPM | 60 mm/mphindi | 0.05 mm/kutembenuka |
| 600 RPM | 60 mm/mphindi | 0.10 mm/kutembenuka |
| 300 RPM | 60 mm/mphindi | 0.20 mm/kutembenuka |
Gome 2 Yowerengedwa pogwiritsa ntchito fn = Vf / n. Mizere yonse itatu imagwiritsa ntchito liwiro lofanana la chakudya.
Chithunzi 3 Ndi chakudya chokhazikika pa 60 mm/min, kugawa pakati kwa RPM kumawirikiza kawiri chakudya pa kuzungulira kulikonse. Kutalika kwa bala kumasonyeza kupita patsogolo kwa axial pa kuzungulira kulikonse, osati mphamvu yodula.
Kuchepetsa liwiro kuchokera pa 600 mpaka 300 RPM kumawirikiza kawiri liwiro la advance pa kutembenuka kulikonse. Ngati mtengo watsopanowo ndi wokwera kwambiri pa kubowola ndi kukhazikitsa, kupitirira muyeso kumatha kuchitikabe. Kukweza RPM mukamagwira ntchito yokhazikika ya mm/min kumakhala ndi zotsatira zosiyana ndipo kumachepetsa advance pa kutembenuka kulikonse.
Yang'anani momwe makina amawongolera chakudya. Pamene chakudya chayikidwa mu mm/rev, chowongolera nthawi zambiri chimasintha mm/min ndi RPM kuti chisunge patsogolo chomwe chasankhidwa pa kutembenuka kulikonse. Tsimikizani momwe makina amagwirira ntchito komanso momwe makina amagwirira ntchito musanasinthe makonda.
Pa chobowolera chodyetsedwa ndi manja, kupanikizika si njira yokhazikika yodyetsera. Mitengo yowerengedwa pamwambapa singasinthidwe mwachindunji kukhala mphamvu yolimbikitsidwa ndi manja.
7 Yang'anani mikhalidwe musananene mlandu RPM
Chizindikiro chimodzi chingakhale ndi zifukwa zingapo. Gwiritsani ntchito macheke otsatirawa kuti muwongolere kafukufuku; tebulo silizindikira kuyesera kolephera lokha.
| Vuto lomwe lawonedwa | Macheke oti aphatikizepo |
| Chida chaufupi | Liwiro, chakudya, kusankha kubowola ndi choziziritsira kufika pamalo oyenera. |
| Makona akunja owonongeka | Liwiro lopitirira muyeso, choziziritsira ndi malo olimba mu workpiece. |
| Kusweka mwadzidzidzi | Kulongedza zip, kudyetsa kwambiri, m'mphepete mosweka komanso kutsekeka kolimba. |
| Dzenje lalikulu kwambiri | Kuyika pakati pa mfundo, momwe spindle imagwirira ntchito komanso momwe zinthu zimayendera. |
Kwa ogula ndi ogulitsa, lembani mtundu wa zinthu ndi momwe zilili, chitsanzo cha kubowola ndi kukula kwake, kuya kwa dzenje, zida, RPM yogwirira ntchito, njira yodyetsera ndi choziziritsira. Onjezani zithunzi zomveka bwino za m'mphepete mwatsopano, tchipisi ndi gawo lolephera. Izi zimapatsa wogulitsayo umboni wothandiza woyerekeza bwino.
Ogulitsa amakhalabe ndi udindo pa zinthu, kutentha, mawonekedwe ndi kusinthasintha kwa gulu. Malangizo omveka bwino ogwiritsira ntchito amathandiza makasitomala kusintha khalidwe la chinthucho kukhala ntchito yobowola yomwe ingabwerezedwe.
Zokhudza mndandanda uwu
Chifukwa Chake Drill Bits Fail ndi mndandanda waukadaulo wolembedwa ndi gulu lathu lopanga. Nkhani iliyonse imayang'ana kwambiri chinthu chimodzi chomwe chimagwira ntchito bwino pa drill bit - kuyambira pazinthu zopangira mpaka kulongedza. Cholinga chake ndi chosavuta: kuthandiza ogula kumvetsetsa zomwe akugula, komanso mafunso oti afunse.
Zolemba zowerengera
Ma graph point onse ndi ma RPM values amawerengedwa, osati zotsatira za magwiridwe antchito zomwe zimayesedwa. Ma equation amagwiritsa ntchito D mu mm, Vc mu m/min, n mu RPM, fn mu mm/rev ndi Vf mu mm/min.
