Nyaya: Nei Zvidimbu Zvekudhonza Zvichikundikana | Chinyorwa 16
Mazwi akakosha: chibooreso chisina kururama RPM, chibooreso chebhiti, HSS chibooreso chebhiti RPM, chibooreso chekucheka, chibooreso chekukurumidza uye chifukidzo, dhayamita yebhiti redhiri neRPM, chibooreso chesimbi isina tsvina, chibooreso chenguva imwe neimwe, kuchekwa kwebhiti redhiri, kupwanyika kwebhiti redhiri, kuomarara kwebasa resimbi isina tsvina, nei zvibooreso zvichikundikana
Chibooreso chinogona kukundikana nekukurumidza kana kumhanya kwacho kusingaenderane nedhayamita yaro, workpiece uye feed. Kurongeka kweRPM kunobatsira kunofanira kusungirirwa kune zvese zvitatu. Kungotenderedza muchina nekukurumidza, kana kuti zvishoma nezvishoma, hazvivimbisi kuti gomba riri nani.
Chinyorwa chino chinotarisa pakushandisa HSS twist drills inoshandiswa musimbi. HSS zvinoreva simbi inomhanya zvikuru. Mareferensi ari pazasi anotsanangura hukama; sarudza marongero ekugadzira kubva padata rekushandisa drill chaiyo nezvinhu.
1 Nzwisisa kumhanya usati wasarudza RPM
| Nguva | Zvinorevei |
| Kumhanya kwechirukiso n muRPM | Kuchinja kungaita mangani miniti yega yega. |
| Kucheka kumhanya Vc mu m/min | Kumhanya kwemucheto wekucheka padhayamita yekunze kwechibooreso. |
| Dhayamita D mu mm | Shandisa dhayamita yekucheka, kwete dhayamita yeshangu yakaderera. |
Pa RPM imwe chete, chibooreso chikuru chine kumhanya kwakanyanya kwekucheka kwekunze. Pa 1,000 RPM, chibooreso che 10 mm chinomhanya kanenge ka3.3 kumhanya kwekucheka kwe 3 mm drill. Aya ndiwo manhamba akaverengerwa, kwete marongero anokurudzirwa.
Mufananidzo 1 RPM yakafanana, kumhanya kwakasiyana kwekucheka. Yakaverengerwa kubva kuVc = πDn / 1000.
2 Kumhanya zvakanyanya kunogona kupfupisa hupenyu hwekuboorera
Chibooreso chinogona kurasikirwa nemucheto waro chisati chatyoka. Kumhanya zvakanyanya uye kusakwana kwekudya kunogona kupfupisa hupenyu hwechishandiso. Kumhanya zvakanyanya kunogonawo kukuvadza makona ekunze. Kuendeswa kwechinotonhodza uye kusarudza chibooreso kunokoshawo.
Mupendero wakasakara ungada simba rakawanda kuti urambe uchicheka. Kuramba uchiita basa usingatarise mupendero uye maitiro acho anogona kushandura dambudziko rekusakara kuita dambudziko rekutyoka. Nyora kuti chibooreso chakakundikana sei uye kuti kukuvara kwakatanga kupi usati wasarudza chekuchinja.
3 Kunonoka hakusi nani nguva dzose
Kumhanya kwakanyanya uye kusakwana kwekuboorwa kwesimbi kunogona kukonzera kutyoka. Zviboorwa zvidiki zvesimbi isingatsvi hazvifanirwe kuitwa otomatiki paRPM yakaderera zvikuru.
Panewo dambudziko rekudyisa. Pamuchina unobata feed mu mm/min, kudzikisa RPM kunowedzera daro rakafambira mberi pakuchinja kwe feed kunze kwekunge mamiriro e feed achichinjawo. Muenzaniso wakashanda paiyozvinotevera zvinoratidza kuti nei izvi zvichikosha.
Kuchinja kumhanya hakugone kugadzirisa workpiece isina kusimba, mupendero wakakuvara kana flute yakazara nemachipisi. Mamiriro iwayo anoda kuongororwa kwawo ega.
4 Simbi isina ngura inoda kuchekwa zvinobudirira
Simbi dzisina ngura dzakadai se304 ne316 dzinogona kushanda nesimba panguva yekuboora. Kuoma kwebasa kunoreva kusimba kunokonzerwa nekuchinja kwepurasitiki. Hazvifanirwe kutsanangurwa sekunge kupisa kunoita kuti simbi iome.
Chengeta chikafu chakakodzera uye usadzvanya kana kukwesha kana chibooreso chikabata chinhu chacho. Machipisi anofanirawo kukwanisa kubuda mugomba. Izvi zvinoda kupinza kwakapinza, chikafu chakakodzera uye kubvisa chips zvinobudirira. Hazvirevi kushandisa simba risingaperi.
Kana chibooreso chikaramba chichitenderera panzvimbo imwe chete chisina kufambisa kana kubvisa chinhu, tarisa mamiriro ekucheka uye mamiriro emucheto. Kukwesha kakawanda kunogona kuita kuti kucheka kunotevera kuve kwakaoma. Usapindura nekuwedzera kumanikidzwa usina kuwana chikonzero.
Izvi zvinorevei mukuita
Bata RPM sechikamu chemaitiro ekuboorera. Ongorora kumhanya pamwe chete nekudyisa, chinotonhodza uye kubvisa machipisi. Chibooreso chakagadzirwa nemazvo chichiri kuda mamiriro akakodzera ekushanda; dambudziko rekushandisa haribvisiwo dambudziko rekugadzira.
5 Tsanangudzo yeHSS yesimbi isingasvibi
HSS cutting-speed reference range yesimbi isingatsvi i30 kusvika 50 surface feet paminiti, yakaenzana ne9.144 kusvika 15.24 m/min. Tafura iri pazasi inoshandura iyo range kuita RPM. Ishandise kuti unzwisise kuti dhayamita inokanganisa sei kumhanya, wobva watarisa marongero echibooreso chaicho nezvinhu.
| Dhayamita yekuboorera | Pa 9.144 m/min | Pa 15.24 m/min |
| 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 |
Tafura 1 RPM yakaverengerwa, yakatenderedzwa kusvika paRPM yese iri pedyo. Kuchinja: 1 ft = 0.3048 m.
Mufananidzo 2. Kumhanya kwakafanana kunoda RPM yakaderera sezvo dhayamita ichiwedzera. Bhandi rine mumvuri inhamba yakatarwa, kwete nzvimbo yekushanda yakachengeteka yakaedzwa.
Iyi imhando yakakura yeHSS. Haipe nzvimbo yakatarwa yeese madhiri emhando yesimbi isina ngura, kuomarara, kuputira kana cobalt HSS. Aya madhiri haasi mazano ezvigadzirwa zveJiacheng M35 kana M42.
Shandisa data remugadziri wechibooreso kutanga. Tarisa giredhi rezvinhu uye mamiriro azvo, kudzika kwegomba, chinotonhodza uye kugona kwemuchina. Usakope chati yekumhanya kwecarbide kune HSS drill.
6 Match RPM ne feed
Feed per revolution fn idaro rinofambiswa nechibhorani panguva imwe chete, mu mm/rev. Kumhanya kwefeed Vf idaro rinofambiswa muminiti imwe, mu mm/min. Hukama hwavo ndehwekuti:
Vf= fnxn
Ngatitii muchina wacho unochengetedza kumhanya kwekudya pa60 mm/min. Kuchinja RPM chete ndiko kunoita kuti pave nematanho anotevera. Uyu muenzaniso wekuverenga, kwete kurudziro yekuboorera.
| Kumhanya kwechirukiso | Kumhanya kwekudyisa | Kudyisa pakuchinja kwega kwega |
| 1,200 RPM | 60 mm/miniti | 0.05 mm/rev |
| 600 RPM | 60 mm/miniti | 0.10 mm/rev |
| 300 RPM | 60 mm/miniti | 0.20 mm/rev |
Tafura 2 Yakaverengerwa uchishandisa fn = Vf / n. Mitsetse yese mitatu inoshandisa kumhanya kwakafanana kwekudyisa.
Mufananidzo 3 Nekudyisa kwakagadzika pa60 mm/min, kupatsanura RPM kaviri kudyisa pakuchinja kwese. Kureba kwebhawa kunoratidza axial advance pakuchinja kwese, kwete simba rekucheka.
Kuderedza kumhanya kubva pa600 kusvika pa300 RPM kunowedzera kaviri advance per turn. Kana kukosha ikoko kutsva kwakanyanya kukwira pakuboorera nekugadzika, overload inogona kuitika. Kukwidza RPM uchibata mm/min constant kune mhedzisiro yakasiyana uye kunoderedza advance per turn.
Tarisa kuti muchina unodzora sei kudya. Kana kudya kwacho kwaiswa mu mm/rev, chinodzora chinowanzo chinja mm/min neRPM kuti chirambe chakasarudzwa pakuchinja kwese. Simbisa maitiro ekushanda uye maitiro emuchina usati wagadzirisa marongero.
Pachibhorani chinodyiswa nemaoko, kumanikidzwa hakusi kurongwa kwekudyisa kwakarongwa. Makoshero akaverengerwa pamusoro apa haagone kushandurwa zvakananga kuita simba remaoko rinokurudzirwa.
7 Tarisa mamiriro ezvinhu usati wapa mhosva RPM
Chiratidzo chimwe chete chinogona kunge chine zvikonzero zvakasiyana-siyana. Shandisa zvinotevera kuti utungamirire kuferefeta; tafura haiongorore kudzidzira kwakundikana yoga.
| Dambudziko rakaonekwa | Macheki anofanira kusanganisira |
| Hupenyu hwezvishandiso hupfupi | Kumhanya, kudya, kusarudza chibooreso uye chinotonhodza zvinosvika padanho. |
| Makona ekunze akakuvara | Kumhanya kwakanyanya, chinotonhodza uye nzvimbo dzakaoma mubasa. |
| Kutyoka kamwe kamwe | Kurongedza machipisi, kudya zvakanyanya, mucheto wakasakara uye kusungirirwa kwakasimba. |
| Buri rakakura | Kuisa pakati penzvimbo, mamiriro echisimbiso uye kufamba kwechinhu chinoshanda. |
Kune vanotenga nevanogovera, nyora giredhi rezvinhu uye mamiriro azvo, modhi yekuboorera nedhayamita, kudzika kwegomba, michina, RPM yekushanda, nzira yekudyisa uye chinotonhodza. Wedzera mapikicha akajeka emucheto wekare, machipisi nechikamu chakakundikana. Izvi zvinopa mutengesi humbowo hunobatsira hwekuenzanisa kwakaringana.
Vatengesi vanoramba vaine mutoro wekugadzirisa zvinhu, kupisa, hunyanzvi uye kuenderana kwemhando yechinhu chacho. Gwaro rakajeka rekushandisa rinobatsira vatengi kushandura kunaka kwechigadzirwa ichocho kuita mashandiro ekuboorera anodzokororwa.
Nezvenyaya iyi
Chikonzero nei Drill Bits Isingashande inyaya yehunyanzvi yakanyorwa nechikwata chedu chekugadzira. Chinyorwa chimwe nechimwe chinotarisa pane chimwe chinhu chaicho mukushanda kwedrill bit - kubva pazvinhu zvisina kugadzirwa kusvika pakurongedza. Chinangwa chiri nyore: kubatsira vatengi kunzwisisa zvavari kutenga chaizvo, uye mibvunzo yekubvunza.
Zvinyorwa zvekuverenga
Mapoinzi ese echati uye RPM values zvinoverengerwa, kwete mhedzisiro yekushanda yakayerwa. Equations dzinoshandisa D mu mm, Vc mu m/min, n mu RPM, fn mu mm/rev uye Vf mu mm/min.
