Ngokuvamile, emva kokusebenzisa i-chiller epholile emoyeni isikhathi eside, ezinye izinkinga azinakugwenywa. Uma kukhona ukwehluleka, kufanele sihlole ngokucophelela izimo zokusebenza zezingxenye ezihlukahlukene zomshini womjovo. Amaphuzu ayinhloko ukuhlola uhlelo lwefriji, uhlelo lukagesi, uhlelo lomoya, kanye nohlelo lwamanzi. Ukwahlulela ukuthi umsebenzi wabo wesikole ujwayelekile yini, umhleli …

Imiphetho eluhlaza a) Qinisekisa ukuthi inani lamafreyimu namandla okubamba omshini womjovo anele b) Qinisekisa ukuthi ingcindezi iphakeme kakhulu 1) Uma isampula engalawulwa lisalokhu inama-burrs, Kusho ukuthi ukuqubuka isikhunta akukuhle noma iphutha liphukile. 2) Uma ukugoqa isikhunta kungalungile futhi nosayizi nawo …

Noma ubani ofuna ukuthenga umshini wokubumba umjovo uzohlangabezana nale nkinga. Lapho uthenga umshini wokubumba umjovo, isikhunta,umshini osizayo kufanele ngithenge omkhulu noma omncane? Kufanele ngithenge eshibhile noma ebiza kakhulu? Izinkulungwane zamaRandi, kuyilapho ezibizayo zibiza amakhulu ezinkulungwane noma izigidi; eminye imishini yokubumba imijovo mikhulu kakhulu ukuthi ingalingana, …

izimo zokubumba umjovo yinto ebalulekile ukuze umnikazi wendawo yokusebenzela akwazi. Ukubumba umjovo kuyimboni enolwazi olubanzi, ubuchwepheshe kanye nokwenza. Plastic izinto zokusetshenziswa, amathoni, izinto zombhobho, isikhunta, imishini yokubumba umjovo, imishini ye-peripheral, izakhiwo, izifutho, izinto ezihlukahlukene ezisizayo kanye nezinto zokupakisha zisetshenziswa ekukhiqizeni umjovo wokubumba, okuletha umsebenzi omningi kubaphathi …

Enqubweni yokubumba umjovo wamapulasitiki, thermoplastics, ngenxa yokushintsha kwevolumu okubangelwa i-crystallization, ukucindezeleka kwangaphakathi okuqinile, ingcindezi enkulu eyinsalela eqandisiwe engxenyeni yepulasitiki, ukuma kwamangqamuzana aqinile nezinye izici, ngakho uma kuqhathaniswa nepulasitiki ye-thermoset, izinga lokuncipha likhulu. Izinga lokuncipha libanzi futhi ukuqondiswa kuyabonakala. Ngaphezu kwalokho, ukuncipha ngemva kokubunjwa, ukufudumala noma umswakama …

Umshini wokubumba umjovo isakhiwo esiyisisekelo sibaluleke ngempela kusomabhizinisi. Ngokwezidingo zenqubo yokubumba umjovo, umshini wokubumba umjovo uyimodeli enama-mechatronics aqinile. Ikakhulukazi yakhiwe izingxenye zomjovo, izingxenye zokubopha, i-fuselage, uhlelo lwe-hydraulic, uhlelo lokushisa, uhlelo lokulawula, idivayisi yokudla, njll. Okwamanje, imishini evamile yokujova indlebe inohlobo lwe-cylinder eyodwa kanye nohlobo lwe-double-cylinder. …

Eyodwa, ukuhlaziywa kwezizathu zokuphuka kwentambo yokubopha umshini wokubumba umjovo Ukuhluleka kokukhathala. Inqubo yokusebenza yomshini wokubumba umjovo iyinqubo yokushintshanisa ukucindezeleka, ngakho-ke noma yisiphi isici esibangela ukugxila kokucindezeleka kungase kuholele ekuhlulekeni kokukhathala. njenge: Isinyathelo lapho ububanzi be-shaft bushintsha kakhulu. Ukuntuleka kwamakhona ayindilinga, ama-undercuts, njll. kwe …

Izinga lokushisa lokuphuka kwesikulufa nalo lihlobene, kodwa kuyivelakancane, cishe sonke isikulufu ngokwaso siwukuqina okubi, noma isikulufu sesisetshenziswe isikhathi eside, lungisa isikulufu! Izinto zokubumba umjovo zilukhuni. Ngokwesibonelo, ukwengeza i-GF [ingilazi fiber] ezintweni zokubumba umjovo yisikulufu esibiza kakhulu nomshini! Le nto yokubumba yomjovo impofu …

I-Acrylic ngamakhemikhali ibizwa nge-polymethyl methacrylate (PMMA ngesiNgisi). Ngenxa yokushiyeka kokuqina kobuso be-PMMA, ukunwaya kalula, ukumelana nomthelela ophansi, ukubumbana okungalungile, njll., ukuguqulwa kwe-PMMA kuvele ngokulandelana. Okufana ne-copolymerization ye-methyl methacrylate nge-styrene ne-butadiene, ukuhlanganiswa kwe-PMMA ne-PC, njll. Ukugeleza kwe-PMMA kubi kunalokho …

Umthelela wesivinini sokushisa kwepulasitiki Ngokuvamile, ngesikhathi sokucisha ukushisa, ngokushesha isivinini sokushisa sepulasitiki, kukhulu ukucindezeleka okushisayo okukhiqizwa esikhunjeni, okungenzeka kubangele ukubola nokuqhekeka kwesikhunta. Ikakhulukazi insimbi ye-alloy nensimbi ye-alloy ephezulu, ngenxa yokungabibikho kwe-thermal conductivity, kufanele kuthathwe izinyathelo zokuphepha ezikhethekile. Ukushisa, kwezinye izimo eziyinkimbinkimbi ze …

Isikhunta sihlangabezana nezidingo zezimo zokusebenza Ukumelana nokugqoka Lapho okungenalutho kukhubazekile ngokwepulasitiki endaweni yokubumba, liyageleza bese liyashelela phezu komgodi, okubangela ukungqubuzana okunamandla phakathi kwendawo yomgodi nokungenalutho, okubangela ukuthi isikhunta sihluleke ngenxa yokugqoka. Ngakho-ke, ukumelana kokugqoka kwempahla kukodwa …

Amaphuzu ayisithupha ayinhloko we-pp injection molding.Ukucubungula kwezinto zokusetshenziswa kwepulasitiki ikakhulukazi ukuncibilika, ukugeleza, uhlobo, bese upholisa ube umkhiqizo oqediwe. Kuyinqubo yokufudumeza bese uyapholisa. Kubuye kube yinqubo lapho ipulasitiki ishintsha kusuka kuma-pellets kuya emimoyeni ehlukene. Okulandelayo kuzochaza ukucutshungulwa ngokwemibono yehlukene …
