Yiziphi Izinqubo Zesakhiwo Zezingxenye Zepulasitiki?
Idizayini yenqubo yesakhiwo yezingxenye zepulasitiki ikakhulukazi ibandakanya ukucatshangelwa okufana nejiyomethri, ukunemba kobukhulu, isilinganiso sokudweba, ukushuba kwendawo, ukushuba kodonga, i-engeli yokusalungiswa, ububanzi bembobo, i-fillet radii, i-engeli yokusalungiswa kwesikhunta, nezimbambo zokuqinisa. Lesi sihloko sizochaza ngephuzu ngalinye kulawa siphinde sixoxe ngokuthi zingenziwa kanjani ngokugcwele lezi zakhi ngesikhathi senqubo ye-thermoforming ukuze kuthuthukiswe ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza.
1. IJiyomethri kanye Nokunemba Kobukhulu
Kusukela ipulasitiki ye-thermoforming kuyindlela yesibili yokucubungula, ikakhulukazi ekwenzeni i-vacuum, kuvame ukuba negebe phakathi kwephepha lepulasitiki kanye nesikhunta. Ukwengeza, ukuncipha nokuguqulwa, ikakhulukazi ezindaweni ezingaphandle, kungabangela ukushuba kwezindonga zibe mncane, okuholela ekwehleni kwamandla. Ngakho-ke, izingxenye zepulasitiki ezisetshenziswa ekwenzeni i-vacuum akufanele zibe nezidingo eziqine kakhulu zejometri nokunemba kobukhulu.
Phakathi nenqubo yokubunjwa, ishidi lepulasitiki elishisayo lisesimweni sokwelula esingenakuvinjelwa, esingaholela ekunciphiseni. Ngokuhambisana nokupholisa okubalulekile kanye nokuncipha ngemva kokudilizwa, ubukhulu bokugcina kanye nokuma komkhiqizo kungase kungazinzi ngenxa yezinga lokushisa nezinguquko zemvelo. Ngenxa yalesi sizathu, izingxenye zepulasitiki ze-thermoformed azifanele ukusetshenziswa kokubumba okunembayo.
2. Dweba Isilinganiso
Isilinganiso sokudonsa, okuyisilinganiso sobude bengxenye (noma ukujula) kuya kububanzi bayo (noma ububanzi), sinquma kakhulu ubunzima benqubo yokwenza. Uma isilinganiso sokudonsa siba sikhulu, kuba nzima kakhulu inqubo yokubumba, futhi makhulu amathuba okuba nezindaba ezingathandeki njengokushwabana noma ukuqhekeka. Izilinganiso zokudweba ezeqile zinciphisa kakhulu amandla nokuqina kwengxenye. Ngakho-ke, ekukhiqizeni kwangempela, ububanzi obungaphansi kwesilinganiso esiphezulu sokudonsa ngokuvamile busetshenziswa, ngokuvamile phakathi kuka-0.5 no-1.
Isilinganiso sokudonsa sihlobene ngokuqondile nobukhulu obuncane bodonga bengxenye. Isilinganiso esincane sokudonsa singakha izindonga eziqinile, ezifanele ukwakheka kweshidi elincanyana, kuyilapho isilinganiso esikhulu sokudonsa sidinga amashidi aminyene ukuze kuqinisekiswe ukuthi ukujiya kodonga akubi kakhulu. Ukwengeza, isilinganiso sokudonsa sihlobene ne-engeli yokusalungiswa kwesikhunta kanye nokunwebeka kwezinto zepulasitiki. Ukuqinisekisa ikhwalithi yomkhiqizo, isilinganiso sokudonsa kufanele silawulwe ukuze kugwenywe ukwanda kwezinga le-scrap.
3. I-Fillet Design
Amakhona acijile akufanele aklanywe emakhoneni noma emaphethelweni ezingxenye zepulasitiki. Esikhundleni salokho, kufanele kusetshenziswe i-fillet enkulu ngangokunokwenzeka, lapho irediyasi yekhona ngokuvamile ingekho ngaphansi kuka-4 kuya ku-5 ukujiya kweshidi. Ukwehluleka ukwenza kanjalo kungabangela ukuncipha kokuqukethwe nokugxilisa ingcindezi, kuthinte kabi amandla nokuqina kwengxenye.
4. I-Engeli Esalungiswa
I-Thermoforming isikhunta, esifana nesikhunta esivamile, sidinga i-engeli ethile yokusalungiswa ukuze kube lula ukubunjwa. I-engeli yokusalungiswa ngokuvamile isuka ku-1° iye ku-4°. I-engeli encane yokusalungiswa ingasetshenziselwa isikhunta sesifazane, njengoba ukuncipha kwengxenye yepulasitiki kunikeza imvume eyengeziwe, okwenza ukubunjwa kube lula.
5. I-Reinforcement Rib Design
Amashidi epulasitiki ane-thermoformed ngokuvamile aba mncane kakhulu, futhi inqubo yokwenza inqunyelwe isilinganiso sokudonsa. Ngakho-ke, ukwengeza izimbambo zokuqinisa ezindaweni ezibuthakathaka ngokwesakhiwo kuyindlela ebalulekile yokwandisa ukuqina namandla. Ukubekwa kwezimbambo zokuqinisa kufanele kucatshangelwe ngokucophelela ukuze kugwenywe izindawo ezincane kakhulu ezansi nasemakhoneni engxenye.
Ngaphezu kwalokho, ukwengeza imifantu engajulile, amaphethini, noma izimpawu phansi kwegobolondo le-thermoformed kungathuthukisa ukuqina futhi kusekele isakhiwo. Imifantu emide engashoni emaceleni ikhulisa ukuqina okuqondile, kuyilapho imifantu ephambanayo engashoni, nakuba ithuthukisa ukumelana nokuwohloka, ingenza ukubhidliza kube nzima kakhulu.
6. Ukuncipha Komkhiqizo
Imikhiqizo ye-thermoformed ngokuvamile kuvame ukushwabana okubalulekile, okucishe kube ngu-50% kwakho okwenzeka ngesikhathi sokupholisa esibunjeni. Uma izinga lokushisa lesikhunta liphezulu, ingxenye ingase inciphe ngokungeziwe ngo-25% njengoba iphola ekamelweni lokushisa ngemva kokudilizwa, bese kuthi u-25% osele wokushwabana wenzeke emahoreni angama-24 alandelayo. Ngaphezu kwalokho, imikhiqizo eyenziwe kusetshenziswa isikhunta sabesifazane ivame ukuba nesilinganiso sokuncipha ngo-25% kuya ku-50% ngaphezu kwaleyo eyakhiwe ngesikhunta sabesilisa. Ngakho-ke, kubalulekile ukucabangela ukushwabana phakathi nenqubo yokuklama ukuze kuqinisekiswe ukuthi ubukhulu bokugcina buhlangabezana nezidingo zokunemba.
Ngokulungiselela ukwakheka kwejiyomethri, isilinganiso sokudweba, i-fillet radius, i-angle yokusalungiswa, izimbambo zokuqinisa, kanye nokuncipha, ikhwalithi nokuqina kwezingxenye zepulasitiki ezishisayo zingathuthukiswa kakhulu. Lezi zingxenye zedizayini zenqubo zinomthelela obalulekile ekusebenzeni kahle kokukhiqiza nokusebenza kwemikhiqizo efakwe i-thermoform futhi zibalulekile ekuqinisekiseni ukuthi imikhiqizo ihlangabezana nezidingo zomsebenzisi.
