Mfundo Zinayi Zoyambira Kuzindikira Mphamvu Yolimbana ndi Zida za CNC

Chida cha CNC: Popanga chipangizo chokhomerera, kutsimikiza kwa mphamvu yokhomerera kumaphatikizapo zinthu zitatu: komwe kumenyera mphamvu, komwe kumagwirira ntchito komanso kukula kwa mphamvu yolumikizira.

1. Chitsogozo cha mphamvu ya clamping ya chida cha CNC Chitsogozo cha mphamvu ya clamping chikugwirizana ndi kasinthidwe koyambira kayimidwe ka zigawo zing'onozing'ono ndi njira ya mphamvu yakunja pa workpiece.

Tsatirani malangizo awa posankha zida za CNC:

① Mayendedwe a mphamvu yokhotakhota akuyenera kukhala okhazikika, ndipo mphamvu yotchingira ikuyenera kulunjika pomwe pali maziko.

②Mayendedwe a clamping force akuyenera kukhala othandiza kuchepetsa mphamvu yotchinga kuti muchepetse kusinthika kwa chogwirira ntchito ndikuchepetsa mphamvu yantchito.

③Mayendedwe a mphamvu yokhometsa kuyenera kukhala komwe kuli kolimba kwa chogwiriracho.Popeza kuuma kwa workpiece m'njira zosiyanasiyana sikufanana, malo osiyanasiyana ogwiritsira ntchito mphamvu amawonongekanso mosiyana chifukwa cha kukula kwa malo okhudzana.Makamaka pamene clamping mbali woonda-mipanda, chisamaliro ayenera kumwedwa kuti malangizo a clamping mphamvu kuloza ku mbali ya rigidity wa workpiece.

2. Malo ochitirapo mphamvu ya clamping ya chida cha CNC Malo ogwirira ntchito a clamping force amatanthauza kadera kakang'ono komwe gawo lotsekera limalumikizana ndi chogwirira ntchito.Vuto losankhira malo ochitirapo kanthu ndikuzindikira malo ndi kuchuluka kwa clamping force action point pansi pamikhalidwe yoti kuwongolera kwakhazikika.Kusankhidwa kwa clamping Force point ndiye chinthu chomwe chimapangitsa kuti pakhale malo abwinoko, ndipo kusankha koyenera kwa clamping Force point kumatsatira mfundo izi:

200 Mtengo wa roughness wa pogayo umachepetsedwa kuchokera ku 2.0 mpaka 1.1 CNC chida

3. Kugwiritsa ntchito mphamvu kwa CNC chida processing ndi otsika, kupulumutsa kupanga zinthu.Mukamadula pa liwiro lalikulu, kuchuluka kwa zinthu zosanjikiza zodulidwa ndi mphamvu ya unit kumawonjezeka kwambiri.Monga aloyi ya Lockheed Aircraft Company aloyi yodula kwambiri, liwiro la spindle limachokera ku 4 000 1/….Pamene kuchuluka kwa 20 000, mphamvu yodula idatsika ndi 30 ^, pamene chiwerengero chochotsa zinthu chinawonjezeka ndi 3 nthawi.Mtengo wochotsa zinthu pa mphamvu ya unit ukhoza kufika 130 ~ 160 (1) kuposa 'kung'amba', pamene mphero wamba ndi 30 'kung'amba.Chifukwa cha kuchuluka kwa kuchotsera komanso kugwiritsa ntchito mphamvu zochepa, nthawi yopangira ntchito

Ndi lalifupi, limapangitsanso kuchuluka kwa mphamvu zogwiritsira ntchito mphamvu ndi zipangizo, ndipo limachepetsa chiwerengero cha kudula processing muzinthu zopangira zinthu.Choncho, kudula kothamanga kwambiri kumakwaniritsa zofunikira za ndondomeko yachitukuko chokhazikika.

4. Zida za CNC zimachepetsa ndondomekoyi ndikuchepetsa ndalama zopangira.M'zinthu zina, khalidwe lapamwamba la mphero yothamanga kwambiri limafanana ndi kugaya, ndipo mphero yothamanga kwambiri ingagwiritsidwe ntchito mwachindunji monga njira yomaliza yomaliza.Choncho, njira zaumisiri zimakhala zosavuta, mtengo wopangira umachepetsedwa, ndipo phindu lachuma ndi lalikulu.

Zachidziwikire, mphero yothamanga kwambiri ilinso ndi zovuta zina, monga zida zamtengo wapatali ndi zida zamakina (kuphatikiza makina a CNC), zofunika kwambiri pakuchita bwino kwa zida za CNC, komanso moyo wotsika wa spindle.
