Kudula deta kwa kutembenukira: mwachidule, makhalidwe ndi kusankha luso

Kuti usinthe ndi billet wamba mu item oyenera limagwirira ntchito kutembenuka, mphero, akupera ndi makina ena. Ngati mphero zingamuthandize zotsimikizira mbali zina, monga magiya, kudula slits, ndiye kutembenukira ntchito kuti akonze mbali wosavuta ndi kuwapatsa mawonekedwe ankafunila (phirilo yamphamvu, NW). zinthu kudula kwambiri kukubwezani, chifukwa Mwachitsanzo, metal frangible zofunika ntchito m'munsi kasinthasintha liwiro kuposa cholimba.

Features kutembenuza

Pofuna zokhala mbali zina pa lathe ndi, amakonda kugwiritsa ntchito cutters. Iwo anabwera mu Mabaibulo osiyanasiyana ndipo anawagawira ndi mtundu wa mankhwala, kudya malangizo ndi mawonekedwe mutu. Komanso, osema miyala zopangwidwa kuchokera ku zipangizo zosiyanasiyana: zitsulo aloyi, mpweya, chida, mkulu-liwiro, tungsten carbide.

Chisankho zimadalira workpiece chuma, maonekedwe ake ndi njira kusinja. Kudula deta kwa kutembenukira kwenikweni kuganizira mfundo zina zabwino onsewa. Mu akusandutsa workpiece chili mu spindle, iwo amachita zazikulu makina apaulendo. caliper The wayikidwa akhale chida processing, ndi chakudya gulu anapangidwa kwa iwowo. Malinga ndi makina ntchito akhoza kusamalira onse mfundo zabwino yenewo.

Zinthu zazikulu

Kodi mfundo za zinthu kudula kwa kutembenukira angagwiritsidwe ntchito? Ngakhale kuti anatembenukira - si kophweka kwambiri opareshoni, zinthu zikuluzikulu - ndi liwiro, phula, kuya, m'lifupi ndi makulidwe. magawo onsewa zimadalira kwenikweni pa workpiece zakuthupi ndi kukula. Chifukwa zinthu zazing'ono kwambiri, monga kudula liwiro amusankha otsika, chifukwa ngakhale millimeters 0,05 amene mwangozi kudula, kungachititse kuti ukwati gawo lonse.

Ndi zinthu zofunika kwambiri kuti kudziwa kusankha kudula zinthu kutembenukira zofunika lomwe anapanga. Taganizirani zofunika ndi masitepe zitsulo kudula mwatsatanetsatane.

Wosemera, ndi kutsirizitsa

Kutembenuka mtima kwa workpiece mu item zofunika - zovuta ndi yolemetsa ndondomeko. Iwo agawidwa magawo enieni: wosemera, ndi kuwamaliza. Ngati katunduyo ndi yosavuta, wapakatikati (poluchistovoy) siteji nthawi si n'komwe. Mu ndime yoyamba (akhakula) mwatsatanetsatane atipatse mawonekedwe chofunika ndi miyeso idzatha. Pankhaniyi, onetsetsani kuti ndi msoko ankamvetsa pa masitepe lotsatira. Mwachitsanzo, workpiece wapatsidwa: D = 70 mamilimita ndi L = 115 mm. Chifukwa m'pofunika zokhala mwatsatanetsatane, kukula woyamba _1, D = 65 mm, L ₁ = 80 mm, ndipo chachiwiri - D ₂ = 40 mm, L ₂ = 20 mm.

Wosemera adzakhala motere:

1. Clip kutha kwa 14 mm.
2. Machined awiri pamodzi lonse kutalika 66 mamilimita
3. Inst awiri chachiwiri D ₂ = 41 mamilimita pa kutalika 20 mm.

Pa nthawi imeneyi, tikuona kuti katunduyo sanali kwathunthu kukonzedwa, koma pafupi zotheka mawonekedwe ake ndi kukula. A gawo mu utali wonse ndipo aliyense wa diameters wa mamilimita mpaka 1.

Kumaliza gawo ili adzakhala zotsatirazi:

1. Zo mapeto yokonza ndi roughness kutero.
2. Machined pamodzi kutalika kwa mamilimita 80 m'mimba mwake 65 mm.
3. Thamangani mapeto wotembenukira kutalika 20 mm m'mimba mwake 40 mm.

Pamene ife tikuwona, kutsirizitsa amafuna mwatsatanetsatane pazipita, pachifukwa ichi, ndi kudula liwiro adzakhala zochepa.

Kodi kuyamba mawerengedwe

Pofuna kuwerengera mode kudula, choyamba muyenera kusankha chida zakuthupi. Izo zimadalira workpiece zakuthupi ndi mtundu ndi siteji ya processing. Komanso zambiri zothandiza ankaona cutters imene kudula gawo ndi zochotseka. M'mawu ena, yekha ayenera kusankha zinthu akadaulo ndi kulumikiza kwa kudula chida. The mode yabwino kwambiri ndi imodzi mwa njira zimene mtengo wa katunduyo chopangidwa adzakhala kuthungo. Choncho, ngati inu kusankha zolakwika kudula chida, zikuoneka kuti ndisiye ndipo uyu adzachititsa kuwonongeka. Choncho kodi mungadziŵe zipangizo zofunika ndi zinthu kudula kukubwezani? Gome m'munsimu zingakuthandizeni kusankha chida bwino.

The makulidwe a kudula wosanjikiza

Monga tanena kale, aliyense wa masitepe processing amafuna ena mwatsatanetsatane. zofunika kwambiri ndi zizindikiro izi ndi mawerengedwe a kukameta ubweya wosanjikiza makulidwe. Kudula deta kwa kutembenukira kuonetsetsa kusankha mfundo kwambiri mulingo woyenera kwambiri mfundo vytachivaniya. Ngati sitisamala iwo ndi osachita ndi mawerengedwe, n'zotheka kuti aswe kudula chida ndi katunduyo yokha.

Choncho, choyamba muyenera kusankha makulidwe a kukameta ubweya wosanjikiza. Pamene chida chimadutsa zitsulo, akadula mbali. The makulidwe kapena kuzama kwa odulidwa (T) - ndi mtunda chida adzachotsa mu chiphaso limodzi. Nkofunika kuganizira kuti aliyense pambuyo processing n'kofunika kuchita mawerengedwe a zinthu kudula. Mwachitsanzo, kuchita mbali kunja kutembenuza D = 33,5 mamilimita awiri D ₁ = 30.2 mamilimita ndi mkati wotopetsa dzenje anthu d = 3.2 mamilimita D ₂ = 2 mm.

Pakuti aliyense wa nchito za mawerengedwe a zinthu kudula adzakhala zosiyana pa kutembenuka. Pofuna kudziwa kuya kwa odulidwa, awiri a processing zofunika pambuyo Kuchotsera m'mimba mwake wa workpiece ndi kugawaniza ndi awiri. Chitsanzo chathu chikakhala:

T = (33,5 - 30,2) / 2 = 1,65 mamilimita

Ngati diameters ndi kusiyana waukulu kwambiri, mwachitsanzo 40 mm, ndiye, monga ulamuliro, ayenera kugawidwa ndi 2, komanso chiwerengero chifukwa ndi chiwerengero cha mipita, ndi kuya zizigwirizana millimeters awiri. Pamene akatembenukira akhakula akhoza kusankha kuya kwa odulidwa kuchokera 1 mpaka 3 mm, pamene kutsirizitsa kwa - kuchokera 0.5 kuti 1 mm. Ngati cropping imagwiridwa mapeto padziko, ndi makulidwe a chuma akufukulidwa adzakhala kuya kwa odulidwa.

Kusankha mwa kundipatsako kuchuluka

Mawerengedwe a zinthu kukubwezani zodabwitsa popanda kuchuluka kwa kayendedwe ka kudula chida pa zinthu ndi zolowa kudula - otaya (S). kusankha umadalira pa mlingo zinafunika yolinganizika ndi roughness wa workpiece, ngati ukutha. Pamene wosemera ndi chovomerezeka ntchito otaya pazipita, zochokera mphamvu zakuthupi ndi chinthu chimodzimodzi unsembe wake. Sankhani otaya anakhumba akhoza kugwiritsa ntchito tebulo pansipa.

Pambuyo S asankhidwa kale, m'pofunika kuti anthu amvetse mu makina pasipoti.

kudula liwiro

Nkofunika, zokhudza zinthu kudula mu kutembenuza ndi kudula liwiro (v) ndi spindle liwiro (n). Pofuna kugwira ntchito zowerengetsa kufunika koyamba kugwiritsa ntchito mfundo:

V = (π X D × n) / 1,000

kumene π - PI wofanana 3,12;

D - pazipita awiri a magawo;

N - liwiro spindle.

Ngati phindu chatha amakhalabe zikutsatiridwa, liwiro rotational adzakhala ambiri ikuluikulu awiri a preform lapansi. chilinganizo Izi ndi abwino pamene litayamba rotational liwiro, mwinamwake m'pofunika kugwiritsa ntchito njira:

_ndime = (C ndime × K _v) / (T _mamita × T × S),

kumene T ndi S - kale masamu kudula mozama ndi chakudya, ndi C _ndime, K _ndime, T - koefishienti amadalira katundu mawotchi ndi kapangidwe ka zinthu. makhalidwe awo angathe kumwedwa mu magome a zinthu kudula.

zinthu Chiwerengero kudula

Amene angakuthandizeni kuchita mawerengedwe kudula zinthu pamene kutembenukira? mapulogalamu Online pa zinthu zambiri Intaneti kupirira ntchito bwino kuposa munthu.

N'zotheka ntchito zofunikira monga kompyuta n'kupuma kapena pa foni. Iwo omasuka kwambiri ndipo popanda luso. M'munda m'pofunika kulowa chofunika mfundo za: chakudya, akuya odulidwa, ulusi workpiece ndi kudula chida, komanso mbali zonse zofunikira. Izi kupereka mabuku ndipo mofulumira mawerengedwe deta zonse zofunikira.
