Analysis na hankula daidaitattun sassa na inji: faranti machining

Sashe na 1. Halayen tsarin sassa na faranti

Sassan farantin su ne sassa masu lebur a matsayin babban jiki, yawanci sun ƙunshi ramukan zaren, ƙananan filaye masu goyan baya, ramuka masu ɗaukar hoto, ramukan rufewa, maɓalli da sauran saman.

Sashe na 2. Bukatun fasaha don sassan farantin karfe

(1) An raba sassan farantin juzu'i mafi yawa zuwa kashi biyu: ana amfani da ɗayan azaman kayan aikin dubawa kuma shine ma'auni na kowane yanki na aunawa.Madaidaicin yanayin sa yana da girma, kuma matakin haƙuri yawanci IT3 ~ IT4 ne.Abin da ake bukata shine gano matakin bambancin sassan.Aƙalla sau 3;sauran nau'ikan nau'ikan ana amfani da su tare da manyan sassa, kuma ana buƙatar jurewar yanayin su gabaɗaya don zama IT5 ~ IT6, wanda shine matakin ɗaya sama da manyan sassan da suka dace.(2) Hakuri na Geometric Don daidaitawa, tsayin daka, da daidaiton filaye masu mahimmanci kamar saman sama da na ƙasa, filaye na waje, da saman sassa na farantin karfe, kurakuran ya kamata a iyakance gabaɗaya zuwa kewayon juriyar juzu'i.
(3) Ƙaƙƙarfan saman saman da aka sarrafa na farantin yana da buƙatun rashin ƙarfi, waɗanda gabaɗaya an ƙaddara bisa ga aiki da tattalin arziƙin sarrafawa, da kuma daidaiton amfani da samfur.Matsakaicin yanayin jirage na kayan aikin dubawa yawanci Ra0.2 ~ 0.6μm ne, kuma yanayin daɗaɗɗen sassan jirage shine Ra0.6 ~ 1.0um.

Sashe na 3. Gudanar da fasahar sarrafa sassan faranti

Don sassan da ke da madaidaicin buƙatun, roughing da ƙare ya kamata a sarrafa su daban don tabbatar da ingancin sassan.A aiki na farantin sassa za a iya kullum a kasu kashi uku matakai: m milling (m milling na karshen fuska, m milling na karshen fuska, m), Semi-karshe milling (Semi-ƙara milling na karshen fuska, Semi-lafiya m, hakowa da tapping na kowane threaded rami), m milling da lafiya m, wani lokacin domin a cimma sosai high surface ingancin da flatness bukatun, a lebur nika tsari ake bukata.

Sashe na 4. Zaɓin kayan abu don sassan farantin karfe

(1) Abubuwan sassan faranti ana yin su ne da baƙin ƙarfe.Don faranti waɗanda ke buƙatar madaidaicin madaidaici da tsauri mai kyau, ana iya amfani da ƙarfe 45, 40Cr, ko ductile baƙin ƙarfe;don babban sauri, faranti masu nauyi, ƙananan ƙarfe mai ƙarancin carbon kamar 20CrMnTi20Mn2B, 20Cr, ko 38CrMoAI ammonia karfe za a iya amfani da su.
(2) Blanks na farantin sassa Bayan dumama da ƙirƙira na blanks kamar karfe 45, na ciki fiber tsarin na karfe za a iya rarraba a ko'ina tare da surface don samun mafi girma tensile ƙarfi, lankwasawa ƙarfi da kuma torsion ƙarfi.Ana iya amfani da simintin gyare-gyare don manyan faranti ko faranti masu sarƙaƙƙiya.

Sashe na 5. Bukatun maganin zafi don sassan farantin karfe

1) Kafin sarrafawa, ƙirƙira ƙirƙira dole ne a daidaita shi ko anneal don tace hatsi na ciki na ƙarfe, kawar da damuwa, rage taurin kayan, da haɓaka iya aiki.
2) Quenching da tempering ne gaba ɗaya shirya bayan m milling kuma kafin Semi-kammala milling don samun mai kyau m inji Properties.
3) Gabaɗaya ana shirya kashe saman ƙasa kafin a gama, ta yadda za a iya gyara nakasar gida ta hanyar quenching.4) Faranti tare da madaidaicin buƙatun dole ne su kuma sha maganin tsufa mai ƙarancin zafin jiki bayan kashe gida ko kuma niƙa.
