Njira yopangira mphero

M'kati mwa mphero, mphero zimatha kugawidwa m'mitundu iwiri: mphero pansi ndi mphero, malingana ndi mgwirizano wapakati pa kasinthasintha wa mphero ndi njira yodulira chakudya. Pamene kasinthasintha malangizo wodula mphero ndi chimodzimodzi ndi workpiece chakudya malangizo, amatchedwa kukwera mphero. Njira yozungulira ya chodula mphero ndi yotsutsana ndi njira yopangira chakudya, yomwe imatchedwa mphero yokwera.

Kukwera mphero nthawi zambiri kumagwiritsidwa ntchito popanga zenizeni. Mphamvu yogwiritsira ntchito mphero ndi yaying'ono kusiyana ndi yokwera pamwamba. Pansi pamikhalidwe yodula yomweyi, mphamvu yogwiritsira ntchito mphero ndi 5% mpaka 15% yotsika, komanso imathandizira kuchotsa chip. Nthawi zambiri, njira yogwetsera pansi iyenera kugwiritsidwa ntchito momwe mungathere kuwongolera kumalizidwa kwapamwamba (kuchepetsa kuuma) kwa magawo opangidwa ndi makina ndikuwonetsetsa kulondola kwake. Komabe, pakakhala wosanjikiza wolimba, kudzikundikira kwa slag pamalo odulira, ndipo pamwamba pa chogwiriracho ndi chosagwirizana, monga machining forging blanks, njira yopangira mphero iyenera kugwiritsidwa ntchito.

Pa mphero yokwera, kudula kumasintha kuchoka ku wandiweyani mpaka kuonda, ndipo mano odulira amadula pamwamba osapangidwa ndi makina, zomwe zimapindulitsa kugwiritsa ntchito odula mphero. Pa mphero, mano odula a wodulayo akalumikizana ndi chogwirira ntchito, sangathe kudula muzitsulo, koma amasuntha mtunda waufupi pamwamba pa chogwiriracho. Ndikosavuta kupanga wosanjikiza wowuma, womwe umachepetsa kulimba kwa chida, umakhudza kumapeto kwa workpiece, ndikubweretsa zovuta pakudula.

Kuphatikiza apo, pamphero, popeza mano odulira amadulidwa kuchokera pansi mpaka pamwamba (kapena kuchokera mkati kupita kunja), ndipo kudula kumayambira pamtunda wolimba, mano odulawo amakhala ndi katundu wambiri, ndipo chodula mphero chimakhala chopepuka mwachangu, koma mano odulira amadula. Palibe chodabwitsa pakuchitapo, ndipo tebulo logwirira ntchito silisuntha panthawi yodula. Mmwamba mphero ndi pansi mphero, chifukwa kudula makulidwe ndi osiyana pamene kudula mu workpiece, ndi kukhudzana kutalika pakati pa mano odula ndi workpiece ndi osiyana, kotero kuvala digiri ya mphero wodula ndi osiyana. Mchitidwewu ukuwonetsa kuti kulimba kwa mphero yomaliza ndi 2 mpaka 3 kuposa momwe mphero imagwera pansi. nthawi, roughness pamwamba akhoza kuchepetsedwa. Koma mphero si yoyenera mphero workpieces ndi khungu lolimba.
