Intambo ihlukaniswe ikakhulukazi ngentambo yokuxhuma nentambo yokushayela.
Kwentambo yokuxhuma, izindlela zokucubungula eziyinhloko ukuthepha, ukuchusha, ukujika, ukugoqa, ukugcoba, njll. Kwentambo yokudlulisa, izindlela eziphambili zokucubungula zinokujika okunokhahlo nokuhle - ukugaya, ukugaya isivunguvungu - ukujika okunzima nokuhle, njll.
Okulandelayo izindlela ezahlukahlukene zokucubungula:
1. Ukusika intambo
Ngokuvamile, kubhekiswa kunqubo yokufaka imishini entweni yokusebenza enokusika okwakha noma ithuluzi elicasulayo, ikakhulukazi kufaka phakathi ukujika, ukugaya, ukuthepha, ukuchusha, ukugaya nokusika isivunguvungu, njll. yethuluzi lomshini liqinisekisa ukuthi ithuluzi lokujika, umshini wokugaya, noma isondo lokugaya lingahambisa ukuhola okukodwa ngokunembile nangokulinganayo kusiqondiso se-axial sendawo yokusebenza. Ngesikhathi sokuthinta noma ukuchusha, ithuluzi (thepha noma ufe) lizungeza ngokuhlobene nomsebenzi wokusebenza, futhi ithuluzi (noma into yokusebenza) lihamba ngokuholwa yi-axially liholwa yi-groove yokuqala eyenziwe ngentambo.
Intambo yokuvula i-lathe ingenziwa ngethuluzi lokuguqula ifomu noma ithuluzi lekama lentambo (bona ithuluzi lokucubungula intambo). Ukuguqula intambo ngethuluzi lokuguqula ifomu kuyindlela ejwayelekile yokukhiqizwa okukodwa nokukhiqizwa okuncane kwe-batch ngenxa yesakhiwo sayo esilula; intambo yokujika ngentambo yokusika inokusebenza kahle kokukhiqiza, kepha ukwakheka kwethuluzi kuyinkimbinkimbi, ngakho-ke kufanelekile kuphela ekukhiqizeni okuphakathi nokomkhulu kocingo olufushane lwentambo ngentambo encane. Ngokuvamile, ukunemba kwephimbo lokuguqula intambo ye-trapezoidal nge-lathe ejwayelekile kungafinyelela kuphela ebangeni le-8-9 (JB2886-81, okufanayo ngezansi); umkhiqizo noma ukunemba kungathuthukiswa ngokuphawulekayo lapho kwenziwa imicu ngentambo ekhethekile yomucu.
2. Intambo yokugaya
Ukugaya kwenziwa emshinini wokugaya ngentambo nge-disc cutter noma nge-cutter cutter. I-disk milling cutter isetshenziselwa ikakhulukazi ukugaya imicu yangaphandle ye-screw rod, isibungu nezinye izinto zokusebenza. Umsiki wokugaya ikamu usetshenziselwa ukugaya imicu ejwayelekile yangaphakathi nangaphandle nemicu yokuthinta. Ngoba igaywa ngumshini wokusika wokugaya onemiphetho eminingi futhi ubude bengxenye yayo yokusebenza bukhulu kunebude bentambo ezocutshungulwa, into yokusebenza ingacutshungulwa ngokushintshana okungu-1.25 ~ 1.5 kuphela, futhi umkhiqizo uphezulu kakhulu. Ukunemba kwephimbo lentambo yokugaya kungafinyelela ebangeni le-8-9, futhi ubukhulu bendawo ngu-R 5-0.63 μm. Le ndlela ifanelekile ekukhiqizweni ngobuningi bezintambo zokusebenza ngokunemba okujwayelekile noma ngemishini emibi ngaphambi kokugaya.
3. Intambo ukugaya
Isetshenziselwa ikakhulukazi ukucubungula imicu yokwenza umsebenzi onzima ku-grinder yensimbi. Ngokuya ngezinhlaka ezahlukahlukene zesigaba sokuwela kwesondo lokugaya, lingahlukaniswa libe isondo elilodwa lokugaya nelayini lemigqa eminingi yokugaya. Imiphumela ikhombisa ukuthi ukunemba kwe-pitch kwesondo elilodwa lokugaya umugqa kungu-5-6 grade, futhi ubukhulu bendawo ingu-R 1.25-0.08 μm, Kuyinto elula ukugaya ukugqoka amasondo. Le ndlela ilungele ukugaya isikulufa sokuhola ngokunemba, i-gauge yensimbi, isibungu, iqoqo elincane lomsebenzi wobucwebe, kanye ne-relief grinding precision hob. Imigqa yokugaya isondo elinemigqa eminingi ihlukaniswe yaba yindlela yokugaya ende futhi yagawulwa ngendlela yokugaya. Ububanzi besondo lokugaya lendlela yokugaya ubude bungaphansi kobude bomucu ozogaywa, futhi intambo ingagaywa ize ibe ngosayizi wokugcina ngokuhambisa isondo isikhathi eside kanye noma kaningana. Ububanzi besondo lokugunda bokusikwa kwendlela yokugaya bukhulu kunobude bomucu ozogaywa. Isondo lokugaya lisika ebusweni bento yokusebenza ngomsindo, umsebenzi ungagcwaliswa ngemuva kwezinguquko ezingaba ngu-1.25. Ukukhiqiza kuphakeme, kepha ukucacisa kuncane, futhi ukugqoka kwesondo lokugaya kuyinkimbinkimbi ngokwengeziwe. Ukusikwa kwendlela yokugaya kufanelekile ekunciphiseni ompompi bokugaya ngeqoqo elikhulu nokugaya eminye imicu yokubopha.
4. Intambo ukugaya
Uhlobo lwenathi noma isikulufa sohlobo lwentambo yokuncibilikisa okwenziwe ngezinto ezithambile njenge-cast iron kusetshenziselwa ukugaya izingxenye zentambo yomshini ngephutha le-pitch phambili nokubuyela emuva ukujikeleza ukwenza ngcono ukunemba kwephimbo. Ukwehliswa kwentambo yangaphakathi eqinisiwe kuvame ukususwa ngokugaya ukuthuthukisa ukunemba.
5. Ukuthinta nokujaza
Ukuthepha ukusebenzisa inani elithile le-twist ukugoqa ukuthepha emgodini ongezansi we-workpiece ukucubungula imicu yangaphakathi. Umkhono ukusebenzisa i-die ukusika imicu yangaphandle kwento yokusebenza (noma ipayipi). Ukunemba kwemishini ngokuthepha noma umkhono kuncike ekunqobeni kompompi noma ekufeni. Yize kunezindlela eziningi zokucubungula imicu yangaphakathi nangaphandle, imicu yangaphakathi yobubanzi obuncane incike ekucutshungulweni kompompi kuphela. Ukuthepha nokufaka imicu kungenziwa ngesandla, njengama-lathes, imishini yokuprinta, ukuthepha nokufaka imishini.
Isimiso sokukhetha sokusika amapharamitha entambo yensimbi
Ngoba umdwebo ucacisa iphimbo (noma ukuhola) kwentambo, ukhiye wokukhetha imingcele yokusika ukucacisa isivinini sokuphotha "n" nokusika ukujula "ap".
1) Ukukhethwa kwejubane lokuphotha
Ngokwendlela umshini wokuphotha ojikeleza ngayo, ukujika okukodwa nethuluzi liphakela ukuhola okukodwa lapho kuvulwa intambo, isivinini se-spindle esikhethiwe sinquma isivinini sokuphakela se-CNC lathe. Ukuhola ngentambo (iphimbo uma kwenzeka intambo eyodwa) esigabeni sohlelo lokucubungula intambo kulingana nesivinini sokuphakelayo "vf" esivezwe ngesilinganiso sokuphakelayo "f (mm / r)".
vf = nf (1)
Kungabonakala kwifomula ukuthi isivinini sokuphakelayo "vf" silingana ngqo nezinga lokuphakelayo "f". Uma isivinini sokuphotha sethuluzi lomshini sikhethwe ukuba siphezulu kakhulu, isivinini sokuphakelwa esiguquliwe kufanele sibe ngaphezulu kakhulu kunesivinini sokuphakelayo esilinganisiwe sethuluzi lomshini. Ngakho-ke, ukusethwa kwepharamitha kohlelo lokuphakelayo kanye nokucushwa kukagesi kwethuluzi lomshini kufanele kubhekwe lapho kukhethwa ijubane lokuphotha lapho kuvulwa intambo, ukugwema ukuvela "kwentambo ekhubazekile" noma iphimbo eliseduze nendawo yokuqala / yokuphela engahlangani izidingo.
Ngaphandle kwalokho, kufanele kuqashelwe ukuthi lapho ukucutshungulwa kwentambo sekuqalisiwe, inani lejubane lokuphotha alinakuguqulwa ngokujwayelekile, futhi ijubane lokuphotha kufaka phakathi imishini yokuqeda kufanele lisebenzise inani elikhethiwe ngesikhathi sokuphakelwa kokuqala. Ngaphandle kwalokho, uhlelo lwe-CNC luzodala "intambo ehlukanisiwe" ngenxa ye- "overshoot" yesiginali ye-pulse signal ye-pulse encoder.
2) Ukukhethwa ukusika ukujula
Ngenxa yamandla wamathuluzi ampofu, isilinganiso esikhulu sokusika okuphakelayo, nokuphakelwa okukhulu kokusika kusuka entanjeni ephendukela ekubunjweni, ngokuvamile kuyadingeka ukwenza imishini yokuphakela okuyingxenye bese ukhetha ukujula okusikayo okufanelekile ngokuya ngomkhuba owehlayo. Ithebula 1 libala amanani wesethenjwa wezikhathi zokuphakelwa nokusika kokujula kokusika kwentambo evamile yemethrikhi.
