Isinyithi esenza yinkqubo yokulungisa ngokutsha icwecwe lesinyithi okanye isitokhwe sekhoyili sibe ngamalungu amathathu-ntathu ngokuguqulwa kweplastiki elawulwayo. Ngokungafaniyo nemisebenzi yokusika okanye umatshini osusa izinto eziphathekayo, ukubunjwa kuyatshintsha ukumila kwesinyithi ngelixa ugcina umthamo wayo. Isiphumo siyinxalenye yesakhiwo okanye esebenzayo kunye nejometri, amandla, kunye nemeko yendawo echazwe yi-tooling kunye neeparitha zokucinezela.
Sibonelela ngeenkonzo zokwenza isinyithi njengenxalenye yobuchule bethu bokwenza isitampu kunye nokuchaneka. Imisebenzi yokubumba isetyenziswa ngokuzimeleyo kunye nokudityaniswa ngaphakathi kwenkqubela phambili, i-compound, kunye ne-die tooling yokudlulisela ukuvelisa iinxalenye ezinzima kulandelelwano olulodwa olulawulwayo.
Ngaba ufuna inxenye yentsimbi eyenziweyo? Thumela umzobo wakho, imathiriyeli, ubukhulu, kunye nevolumu ku- Iindawo zesitampu zentsimbi ezenziwe ngokwezifiso zenziwe kumzobo wakho wobunjineli, ifayile yeCAD, okanye isampuli yomzimba. Inxalenye yejometri, ukucaciswa kwemathiriyeli, ukunyamezelwa komda, ukugqitywa komphezulu, kunye neemfuno zokupakisha zonke zichazwa ngumthengi. Umsebenzi womenzi kukutolika ezo mfuno ngokuchanekileyo kwaye ziguqulelwe kuyilo lwezixhobo, ukhetho lwenkqubo, kunye nokwenziwa kwemveliso ehlangabezana nazo ngokuqhubekayo. ukwenza uphononongo kunye nokucaphula.
Metal Forming Operations Sixhasa
yethu Ukwenziwa kwesinyithi kubandakanya uluhlu olubanzi lwemisebenzi. Ezona zixhaphakileyo kwisitampu sethu kunye neshiti lokwenziwa komda wokwenza intsimbi zibandakanya:
Ukugoba
Ukugoba kusebenzisa amandla ukwenza i-engile okanye iprofayili egobileyo kwisinyithi esicaba. Imisebenzi yokugoba eqhelekileyo ibandakanya ukugoba i-V, ukugoba u-U, kunye nokugoba ukugoba. I-Springback kufuneka ibuyekezwe kuyilo lwezixhobo ngokusekelwe kwibakala lemathiriyeli kunye nobukhulu. Iingqwalasela zoyilo eziphambili zibandakanya ubuncinci be-radius ye-bend (ngokuqhelekileyo i-1 × ubukhulu bezinto eziphathekayo kwiintsimbi ze-ductile), kunye nokugcina ulwalathiso lwenkozo olungaguqukiyo ngokumalunga ne-axis yokugoba.
Umzobo onzulu
Umzobo onzulu usebenzisa i-punch kunye nokufa ukutsala sheet icwecwe lentsimbi radially ngaphakathi, ukwenza iikomityi, amaqokobhe, kunye nezindlu cylindrical. Inkqubo ibonakaliswe ngumlinganiselo wokudweba, ochaza umlinganiselo we-diameter engenanto ukuya kwi-punch diameter. Izinto eziphathekayo kufuneka zibe nobude obaneleyo ukugqiba umzobo ngaphandle kokukrazula. Iiflange, iindonga, kunye neziseko zonke zinokubanjwa kunyamezelo oluluqilima kwisixhobo sokuzoba esiyilwe ngokufanelekileyo. Bona kwakhona: nzulu ukuzoba isitampu.
Coining
ICoining isebenzisa uxinzelelo oluphezulu kakhulu ukwenza ubungakanani obuchanekileyo bento ngokucinezela isinyithi phakathi kwepunch kunye nobuso bokufa. Isiphumo singumgangatho ozinzileyo, ongenaburr kwindawo edityanisiweyo. I-Coining isetyenziswa kwiimpawu apho ulawulo oluluqilima lwe-dimensional, i-radio ebukhali, kunye nomgangatho womphezulu ubaluleke ngaphezu kokunyamezela ukwenza ngokubanzi. Idla ngokusetyenziswa kubuso beterminal, iindawo zoqhagamshelwano, kunye neendawo zokuhlala ezibalulekileyo.
I-Embossing
I-Embossing isusa isinyithi ukudala iimpawu eziphakanyisiweyo okanye ezihlaziyiweyo ezifana neelogo, iimbambo eziqinisayo, iimpawu zokuchongwa, okanye iimpawu zokubhalisa. Izinto eziphathekayo azisuswanga - kuphela zifakwe kwindawo kwiphethini ephakanyisiweyo. Iimpawu ezigxininisiweyo zongeza ukuqina kwesakhiwo kwiindawo ezincinci ngaphandle kokongeza ubunzima.
Flanging
I-Flanging igoba umda weflethi okanye inxalenye eyenziwe ngaphandle okanye ngaphakathi ukuze yenze i-flange. Iiflange zisetyenziselwa ukuqina kolwakhiwo, ukudibana kwendibano, ukutywina, okanye ukukhuselwa komphetho. Imingxuma eyongeziweyo (apho umngxuma ogqojoziweyo ujijelwa ngaphandle ukuze wenze umphathi othungelweyo) ngumsebenzi onxulumeneyo.
Ukuqulunqwa kunye nokunciphisa
Imisebenzi yokubumba ngokubanzi ibumba ngokutsha indawo engenanto ibe ziinkangeleko ezintsonkothileyo ezingasicaba. Ukuqulunqwa kwe-Offset kwenza iiprofayili ze-Z okanye iimpawu ezinyathelweyo kwezinye iindawo ezisicaba. Ezi ziqhelekileyo kwizindlu zokudibanisa, izibiyeli, kunye nenkxaso yendibano.
Uku-ayina
Uku-ayina ngokulinganayo kunciphisa ubukhulu bodonga lweqokobhe elizotyiweyo ukuze kuqinise ukunyamezelwa kwe-dimensional kwi-diameter engaphandle okanye ibhore yangaphakathi. Ihlala isetyenziswa njengomsebenzi wesibini emva komzobo onzulu ukufezekisa ijometri yodonga oluchanekileyo.
Izinto ezisetyenziswa kwiMetal Forming

Cela i-Metal Forming Caphula
Nokuba ufuna igophe elilula okanye iqokobhe elintsonkothileyo lokuzoba, inkqubo yethu yokwenza iqala ngokuqonda iimfuno zokusebenza kwenxalenye yakho kunye neemfuno zokunyamezela. Sihlaziya umzobo, siqinisekisa indlela yokwenza, kwaye sinikezela ngesixhobo kunye nesicwangciso sokuvelisa esixhasa ukuveliswa kwexesha elide.
Uyilo lwesiXhobo sokuSebenza kweMetal.
Umgangatho wenxalenye eyenziweyo uqala ngoyilo lwezixhobo. Wonke umsebenzi wokwenza - nokuba yinto elula ye-90 ° yokugoba okanye umzobo onzima wamanqanaba amaninzi - ifuna i-geometry yesixhobo esichaza ukuziphatha okubonakalayo, i-springback, kunye neemfuno zomda:
- Bend radius kunye nokuvulwa kwe- - umlinganiselo wokufa uvula ubukhulu bezinto eziphathekayo (ububanzi be-V-die) bumisela amandla okugoba afunekayo kunye ne-radius yangaphakathi ye-bend. Izivulo ezincinci zokufa zivelisa i-radio eqinile kodwa ifuna amandla aphezulu kwaye yonyusa umngcipheko wokumakishwa komphezulu.
- Springback imbuyekezo - zonke iintsimbi zibonisa ukubuyiswa kwe-elastic emva kokwenziwa. Isixhobo kufuneka sigqithise inxalenye ngexabiso eliqikelelweyo le-springback ukuze inxalenye egqityiweyo ibuyele kwi-engile ekujoliswe kuyo emva kokukhulula. Uqikelelo lweSpringback lungqale kwimathiriyeli kwaye luqinisekisiwe ngexesha lemveliso yolingo.
- Zoba uyilo lokufa - imisebenzi yomzobo enzulu ifuna ulawulo olucokisekileyo loxinzelelo olungenanto, ukuntywila kunye ne-radius ye-orenji yokuthintela, i-radius ye-punch kunye ne-radius ejikelezayo yeti. iziphene. Imiyinge yomlinganiselo wokuzoba ixhomekeke kwi-ductility yemathiriyeli kunye nobukhulu. I-
- Izixhobo zokudibanisa kunye nokulinganisa - xa iifitsha ezenziweyo zidinga unyamezelo olungqongqo kunokuba ukubunjwa okusemgangathweni kunokufikelela, izixhobo zokuyila zicinezela izinto kubukhulu obuchanekileyo okanye umgangatho ongaphezulu. Oku kongeza isikhululo kwindawo yokufa kodwa inokufikelela kwi-±0.01–0.03 mm kumphezulu odibeneyo.
- i-multi-stage form - iijiyometri ezintsonkothileyo ezingenako ukusekwa kwi-hit enye zifuna izikhululo ezenza ezininzi ngaphakathi kwenkqubela phambili okanye ukufa kokudluliselwa. Isitishi ngasinye sibumba ngokuthe kratya imathiriyeli ukunqanda ukucinezela ngokugqithisileyo nayiphi na indawo enye.
Uyilo lwezixhobo zokwenza imisebenzi kulapho ubunjineli buchaphazela ngokuthe ngqo umgangatho wenxalenye kunye nokuzinza kwemveliso. Siyila zonke izixhobo zokuyila ngaphakathi kwindlu ukugcina ulawulo phezu kolandelelwano lokuqulunqa kunye neqhinga lembuyekezo ye-springback. I-
Ukuziphatha kweMathiriyeli ekuSekweni kweMisebenzi
Iintsimbi ezahlukeneyo ziphendula ngokwahlukileyo ekwenzeni uxinzelelo. Ukuqonda ukuziphatha kwezinto eziphathekayo kubalulekile ekuyileni ukwenza izixhobo ezivelisa iindawo ezihambelanayo:
- Amandla okuvelisa kunye namandla okuqina - izixhobo eziphezulu-zamandla zifuna amandla amaninzi okwenza kwaye zibonise i-springback engaphezulu. Izixhobo ezingaphezulu kwe-500 MPa amandla okuqina zihlala zifuna uhlengahlengiso lokufa kunye nolawulo olungqongqo lwenkqubo. I-
- Ukwandiswa kunye nokunciphisa indawo - le milinganiselo ye-ductility inquma ukuba ingakanani into enokolulwa okanye itsalwe ngaphambi kokuphuka. Izinto ezisezantsi-zobude zinciphisa ubunzulu bomzobo kunye nokuqina kwe-bend radii. I-
- I-exponent yokuqina (n-value) - izinto ezinexabiso eliphezulu le-n-value yokusabalalisa i-deformation ngokulinganayo, enenzuzo yokudweba kunye nokwelula imisebenzi. Izixhobo eziphantsi ze-n-value zikholisa ukwenza i-deformation yendawo kunye nentamo kwangaphambili. I-
- Plastic strain ratio (r-value) - ibonisa ukuchasana kwezinto eziphathekayo ekunciphiseni ngexesha lokudweba. Imathiriyeli yexabiso eliphezulu le-r izoba ngempumelelo kwaye ikhethwa kwizicelo zomzobo onzulu.
- Imeko yomphezulu kunye nokwaleka - uburhabaxa bomphezulu, ukugquma kweoli, kunye neeleyile zegalvanized zonke zichaphazela ukungqubuzana ngexesha lokwenziwa. Ukulungiswa komphezulu wesixhobo kunye nokuthambisa kufuneka kuhambelane nemeko yendawo yezinto.
Idatha yezinto eziphathekayo ezivela kwizatifikethi zokugaya kunye nedatha yethu yovavanyo lwangaphakathi isetyenziswa ngexesha lophononongo lweDFM ukuxela kwangaphambili ukwenza indlela yokuziphatha kunye nokuseta ulindelo lonyamezelo lokwenyani ngaphambi kokuba kuqale ukunyamezela okulindelweyo.
