Kusanthula kwa Ma Taps: Chitsogozo Chokulitsa Kuchita Bwino kwa Ulusi ndi 300% kuchokera ku Basic Selection kupita ku Advanced Technology.
M'munda wa makina processing, Dinani, monga chida chachikulu kwa processing mkati ulusi, mwachindunji chimatsimikizira kulondola kwa ulusi ndi dzuwa kupanga. Kuyambira kupangidwa kwapampopi woyamba wa Maudslay ku UK mu 1792 mpaka kutulukira kwa matepi apadera azitsulo za titaniyamu masiku ano, mbiri ya chisinthiko cha chida ichi chodula chikhoza kuonedwa ngati microcosm ya mafakitale olondola kwambiri. Nkhaniyi ifotokoza mozama zaukadaulo wa Tap kuti zikuthandizeni kukonza bwino pogogoda.
I. Maziko a Tap: Type Evolution and Structural Design
Pompopiyo amatha kugawidwa m'magulu atatu akuluakulu kutengera njira yochotsera chip, ndipo mtundu uliwonse umagwirizana ndi zochitika zosiyanasiyana:
1.Kumpopi kwa katatu(tip-point tap): Mu 1923, linapangidwa ndi Ernst Reime wa ku Germany. Mapeto a kutsogolo kwa groove yowongoka amapangidwa ndi potsetsereka, zomwe zimathandiza kukankhira tchipisi patsogolo kuti zituluke. Kuchita bwino kwa pobowo ndi 50% kuposa kutengera matepi owongoka, ndipo moyo wautumiki umachulukira kuwirikiza kawiri. Ndikoyenera makamaka pokonza ulusi wakuya wazinthu monga chitsulo ndi chitsulo choponyedwa.
2. Spiral groove tap: Mapangidwe a helical angle amathandizira kuti tchipisi titulutsidwe m'mwamba, oyenera kugwiritsa ntchito mabowo akhungu. Mukapanga aluminiyamu, mbali ya 30 ° ya helical imatha kuchepetsa kukana ndi 40%.
3. Ulusi wowonjezera: Alibe popondera chip. Ulusiwo umapangidwa ndi kusinthika kwa pulasitiki kwachitsulo. Mphamvu yamakokedwe ya ulusi imachulukitsidwa ndi 20%, koma kulondola kwa dzenje lapansi ndilokwera kwambiri (chilinganizo: pansi dzenje m'mimba mwake = m'mimba mwake mwadzina - 0,5 × phula). Nthawi zambiri amagwiritsidwa ntchito pazigawo za aluminiyamu yamtundu wa aerospace.
| Mtundu | Chochitika chovomerezeka | Kudula liwiro | Chip kuchotsa malangizo |
| Tap tap | Kudzera dzenje | Liwiro lalitali (150sfm) | Patsogolo |
| Spiral tap | Bowo lakhungu | Liwiro lapakati | Pamwamba |
| Kupanga ulusi pompopi | Zinthu zapulasitiki kwambiri | Kuthamanga kwapansi | Popanda |
Kufananiza magwiridwe antchito amitundu itatu ya matepi
II. Kusintha Kwazinthu: Kudumpha kuchokera ku Zitsulo Zothamanga Kwambiri kupita Kuukadaulo Wopaka
Thandizo lalikulu la magwiridwe antchito a Tap lili muukadaulo wazinthu:
Chitsulo chothamanga kwambiri (HSS): Akaunti yopitilira 70% yamsika. Ndilo kusankha kwapamwamba chifukwa cha kutsika mtengo komanso kukana kwamphamvu kwambiri.
Chitsulo cholimba: Chofunika kwambiri pokonza titaniyamu alloys, ndi kuuma kwa HRA 90.
Tekinoloje yokutira:
TiN (Titanium Nitride): Zovala zagolide, zosunthika kwambiri, kutalika kwa moyo kumawonjezeka ndi nthawi imodzi.
Kupaka kwa diamondi: Amachepetsa mikangano ndi 60% pokonza ma aloyi a aluminiyamu, ndikuwonjezera moyo wautumiki katatu.
Mu 2025, Shanghai Tool Factory idakhazikitsa matepi a titaniyamu aloyi. Ma tapi awa amakhala ndi mapangidwe atatu a arc groove pamtanda (nambala ya patent CN120460822A), yomwe imathetsa vuto la tchipisi ta titaniyamu kumamatira pobowola ndikuwonjezera kugwira ntchito bwino ndi 35%.
III. Njira Zothetsera Mavuto Othandiza Pogwiritsira Ntchito Ma Tap: Zingwe Zosweka, Mano Owola, Kuchepetsa Kulondola.
1. Kupewa kusweka:
Kufananiza kwa dzenje la pansi: Pa ulusi wa M6, dzenje la pansi lofunikira mu chitsulo ndi Φ5.0mm (chilinganizo: M'mimba mwake wa dzenje = Ulusi awiri - Pitch)
Kuyanjanitsa koyima: Pogwiritsa ntchito chuck yoyandama, mbali yolowera iyenera kukhala ≤ 0.5 °.
Lubrication strategy: Mafuta ofunikira opangira madzi opangira titaniyamu alloy pogogoda, kuchepetsa kutentha kwa 200 ℃.
2. Njira Zochepetsera Zolondola
Zovala za dipatimenti ya Calibration: Yesani kukula kwake kwamkati pafupipafupi. Ngati kulolerana kupitilira mulingo wa IT8, sinthani nthawi yomweyo.
Kudula magawo: Kwa chitsulo chosapanga dzimbiri cha 304, liwiro la mzere wovomerezeka ndi 6 m / min. Chakudya pakusintha = phula × liwiro lozungulira.
Kuvala kwapampopi kumathamanga kwambiri. Titha kuchita kugaya pa Tap kuti tichepetse kuvala kwake. Mutha kulumikizana nafe kuti mumve zambiri zaDinani makina akupera.
IV. Kusankha Lamulo Lagolide: Zinthu 4 Zosankha Kupopera Kwabwino Kwambiri
1.Kudzera mabowo / Akhungu mabowo: Pogwiritsa ntchito mabowo, gwiritsani ntchito zobowola zopindika (zokhala ndi zinyalala zakutsogolo); kwa mabowo akhungu, nthawi zonse gwiritsani ntchito zobowola zopindika (zokhala ndi zinyalala kumbuyo);
2. Makhalidwe Azinthu: Chitsulo/Chitsulo Chophimbidwa: Tapu yokutidwa ndi HSS-Co; Titanium Alloy: Carbide + Axial Internal Cooling Design;
3. Kulondola kwa ulusi: Zigawo zachipatala zolondola zimapangidwa pogwiritsa ntchito matepi akupera (kulekerera IT6);
4. Kuganizira Mtengo: Mtengo wamtengo wapampopi wa extrusion ndi 30% wokwera, koma mtengo pa chidutswa chilichonse chopanga misa umachepetsedwa ndi 50%.
Kuchokera pamwambapa, zitha kuwoneka kuti Tap ikusintha kuchokera ku chida wamba kukhala njira yolondola yosinthira zochitika. Pokhapokha podziwa zinthu zakuthupi ndi mfundo zamapangidwe zomwe ulusi uliwonse ukhoza kukhala chibadwa cha kugwirizana kodalirika.
