Kafukufuku pa Njira Yopangira Magalimoto a Shell Castings

Kugwiritsa ntchito zipolopolo zamagalimoto ndizofala kwambiri, ndipo zovuta zake zimatengera kapangidwe kake, kukula ndi zofunikira zaukadaulo. Chipolopolo chamotochi chimagwiritsidwa ntchito m’ma locomotives amagetsi, ndipo zomwe zimafunikira kuti zikhale zapamwamba komanso zamkati za castings ndizokwera kwambiri. Chitsulo chosungunuka chomwe chimagwiritsidwa ntchito kutsanulira chipolopolo cha injini ndi chowotcha kutentha.

Njira yowunikira ma casting a zipolopolo zamagalimoto

Chipinda chamkati cha kumtunda kwa kuponyera chimakhala chovuta kwambiri, chokhala ndi ma protrusions am’deralo; palinso zoziziritsa kutentha zambiri kunja kwa kuponyera; Choncho, pali “T” ndi “L” kutentha mfundo poponya, ndipo n’zovuta kudyetsa kuponyera. Lathyathyathya kuponyedwa ndi kuponya, ntchito chitsanzo ndi yosavuta, koma kudyetsa galimoto chipolopolo kuponyera n’kovuta kwambiri, makamaka kwa protruding mbali ya chapamwamba patsekeke mkati ndi dongosolo zovuta, kwenikweni palibe njira yothetsera vuto kudya.

Kuthira kwa lathyathyathya kapena ofukula molunjika, chokwera chimayikidwa kumapeto kwapamwamba, koma khoma loponyera ndi lakuda, laling’ono ndi lakuda ndipo lapamwamba ndi lochepa thupi, ndipo kuponyera kuli kotalika, kudyetsa kumunsi kumakhala kovuta kwambiri. Kuphatikiza apo, kusinthika kwa castings ndi vuto lomwe liyenera kukumana.

Kusanthula ndi kuwongolera mapindikidwe a chipolopolo chamoto

Kuponyera zipolopolo zamagalimoto si silinda wathunthu. Pali zida zambiri zothandizira monga zomangira zokwezera pa silinda. Kuchuluka kwa khoma la gawo lililonse la kuponyera kumasiyana kwambiri, ndipo kupanikizika panthawi yoziziritsa ndi kulimbitsa kuponyedwa kudzakhala kwakukulu. The deformation chizolowezi cha kuponyera Kulephera kulosera molondola. Kuponyedwa koyamba kwa chipolopolo chamoto kumakhala ndi kusiyana kwa 15 mm m’mimba mwake kumapeto kwa mbiya yowongoka, yomwe imakhala yozungulira kwambiri. Poyika nthiti yoponyera ngati mphete kumapeto kwa mbiya yowongoka, cholakwika chapakati cha kumapeto kwa mbiya yowongoka chimakhala mkati mwa 1mm.
