Makina Ozungulira

Kugubuduza mbale ndi njira yopinda mosalekeza mfundo zitatu zachitsulo pogwiritsa ntchito makina opangira mbale. Zipangizozi zimayika pepala pakati pa mipukutu yapamwamba ndi yotsika pamene ikugudubuza. Chodzigudubuza cham'mwamba chimakwezedwa ndikutsitsidwa molunjika, ndipo zodzigudubuza ziwiri zam'munsi zimazungulira ndikusuntha mopingasa mogwirizana ndi axis ya chogudubuza chapamwamba. Mpukutu wapamwamba ukatsika, mbaleyo imakhala yopunduka ndipo imapindika pakati pa masikono apamwamba ndi apansi. Kuzungulira kosalekeza kwa chodzigudubuza chapansi kumayendetsa mbale yachitsulo kupita patsogolo ndi kubwerera mmbuyo chifukwa cha kukangana kwapakati pa mbale ndi chogudubuza kuti amalize kukulunga.
1. Kupindikatu. Mbaleyo ikakulungidwa, pali utali kumbali zonse ziwiri za mbale yomwe simapindika chifukwa sichikhudza chogudubuza chapamwamba. Imatchedwa mphepete yotsalira yowongoka. Pochita izi, mkono wocheperako womwe mbale imayamba kupindika imatchedwa theoretical yotsalira molunjika. Mawonekedwe opindika (kupindika kofanana, kupindika kwa asymmetrical) amagwirizana.
2. Kukhala pakati. Cholinga cha centering ndi kupanga jenereta wa workpiece kufanana ndi wodzigudubuza axis kupewa skew.
3. Pereka mozungulira. Kugudubuza ndiye njira yayikulu yopangira zinthu, yomwe imagawidwa m'mitundu iwiri: chakudya chanthawi imodzi ndi ma feed angapo. Zakudya zambiri zimagwiritsidwa ntchito pogubuduza mbale zokhuthala. Kuchuluka kwa chakudya kumadalira zopinga zaukadaulo (monga kupindika kwakukulu kovomerezeka panthawi yozizira) ndi zovuta za zida (monga kusatsetsereka ndi mphamvu zamagetsi). Pamene kubwezeretsedwa kwa koyilo kozizira kumakhala kofunikira, kuwonjezereka kwina kumayenera kuwonjezeredwa.
4. Kuwongola kuzungulira. Cholinga cha kuzungulira ndikupangitsa kupindika kwa bwalo lonse kukhala yunifolomu momwe kungathekere kuti zitsimikizire mtundu wazinthu. Njira yozungulira yonse imagawidwa m'magawo atatu:
(1) Katundu: Malinga ndi zomwe zinachitikira kapena kuwerengera, sinthani mpukutu wa ntchito kuti ukhale wokhotakhota wofunikira kwambiri.
(2) Kuzungulira: Perekani chogudubuza 1 mpaka 2 mokhota pansi pa kupindika kokonzedwa kuti mupange yunifolomu yonse yopiringa.
(3) Kutsitsa: kutsitsa pang'onopang'ono katunduyo, kotero kuti chogwirira ntchitocho chimakulungidwa kangapo pansi pa katundu wowongolera pang'onopang'ono.
