Momwe Mungapewere Kuwonongeka ndi Kuphwanyidwa kwa Chithandizo cha Kutentha kwa Nkhungu Kupyolera mu Kupanga Mwanzeru ndi Kusankha Kolondola Kwazinthu?

Gawo.1 kapangidwe koyenera

Chikombolecho chimapangidwa makamaka molingana ndi zofunikira zogwiritsira ntchito, ndipo mawonekedwe ake nthawi zina sangakhale omveka bwino komanso ofanana mofanana.Izi zimafuna kuti wopanga azichita zinthu zogwira mtima popanga nkhungu popanda kusokoneza ntchito ya nkhungu, ndikuyesera kumvetsera ndondomeko yopangira, kulingalira kwa kamangidwe kameneka ndi kufanana kwa mawonekedwe a geometric.

(1) Yesetsani kupewa ngodya zakuthwa ndi magawo omwe ali ndi kusiyana kwakukulu mu makulidwe

Payenera kukhala kusintha kosalala pamphambano ya zigawo zokhuthala ndi zoonda za nkhungu.Izi zingathe kuchepetsa kusiyana kwa kutentha kwa mtanda wa nkhungu, kuchepetsa kupsinjika kwa kutentha, ndipo panthawi imodzimodziyo kuchepetsa kusagwirizana kwa kusintha kwa minofu pamtanda, ndi kuchepetsa kupsinjika kwa minofu.Chithunzi 1 chikuwonetsa kuti nkhungu imatengera kusintha kwa fillet ndi kusintha kosinthira.

(2) Moyenera kuonjezera ndondomeko mabowo

Kwa nkhungu zina zomwe sizingatsimikizire gawo la mtanda ndi symmetrical yunifolomu, m'pofunika kusintha dzenje losadutsa mu dzenje kapena kuonjezera mabowo a ndondomeko moyenera popanda kusokoneza ntchito.

Chithunzi 2a chikuwonetsa kufa ndi kabowo kakang'ono, komwe kadzakhala kopunduka monga momwe mzere wamadontho utatha kuzimitsidwa.Ngati mabowo awiri a ndondomeko akhoza kuwonjezeredwa muzojambula (monga momwe tawonetsera mu Chithunzi 2b), kusiyana kwa kutentha kwa gawo la mtanda pa nthawi ya kuzimitsa kumachepetsedwa, kupsinjika kwa kutentha kumachepetsedwa, ndipo kusinthika kumakula bwino.

(3) Gwiritsani ntchito zida zotsekedwa komanso zofananira momwe mungathere

Pamene mawonekedwe a nkhungu ndi otseguka kapena asymmetrical, kugawanika kwa nkhawa pambuyo pozimitsa kumakhala kosagwirizana ndipo n'kosavuta kupunduka.Chifukwa chake, paziwongolero zopunduka mumphika, kulimbitsa kuyenera kupangidwa musanazimitse, kenako ndikudulidwa mutatha kuzimitsa.The workpiece mumphika chosonyezedwa Chithunzi 3 poyamba anali wopunduka pa R pambuyo kuzimitsidwa, ndi kulimbikitsa (gawo aswa mu Chithunzi 3), akhoza bwino kupewa kuzimitsa deformation.

(4) Kutengera kapangidwe kaphatikizidwe, ndiko kuti, kupanga nkhungu yosokoneza, kulekanitsa nkhungu zakumtunda ndi zapansi za nkhungu yosokoneza, ndikulekanitsa kufa ndi nkhonya.

Kwa zazikulu zimafa ndi mawonekedwe ovuta ndi kukula> 400mm ndi nkhonya zokhala ndi makulidwe ang'onoang'ono ndi kutalika kwautali, ndi bwino kutengera dongosolo lophatikizana, kuphweka zovuta, kuchepetsa zazikulu mpaka zazing'ono, ndikusintha mkati mwa nkhungu kumtunda wakunja. , yomwe siili yabwino kokha kutentha ndi kuzizira.

Popanga chophatikizika chophatikizika, nthawi zambiri chimayenera kuwola motsatira mfundo izi osakhudza kulondola kwake:

• Sinthani makulidwe kuti gawo la nkhungu lomwe lili ndi magawo osiyanasiyana amitundu yosiyanasiyana limakhala lofanana pambuyo pakuwola.
• Ziwola m'malo omwe kupsinjika kumakhala kosavuta kupanga, kufalitsa kupsinjika kwake, ndikuletsa kusweka.
• Gwirizanani ndi dzenje la ndondomeko kuti dongosololi likhale symmetrical.
• Ndi yabwino kwa ozizira ndi otentha processing ndi zosavuta kusonkhana.
• Chofunikira kwambiri ndikuwonetsetsa kuti zikugwiritsidwa ntchito.

Monga tawonera mu Chithunzi 4, ndikufa kwakukulu.Ngati chophatikizikacho chikuvomerezedwa, osati chithandizo cha kutentha chokhacho chidzakhala chovuta, komanso patsekeke chidzachepa mosagwirizana pambuyo pozimitsa, ndipo ngakhale kuchititsa kusamvana ndi kusokonezeka kwa ndege pamphepete mwa m'mphepete mwake, zomwe zidzakhala zovuta kuzikonza pambuyo pokonza., choncho, dongosolo lophatikizana likhoza kutengedwa.Malingana ndi mzere wa madontho mu Chithunzi 4, umagawidwa m'magawo anayi, ndipo pambuyo pa chithandizo cha kutentha, amasonkhanitsidwa ndikupangidwa, ndiyeno pansi ndikufanana.Izi sizimangochepetsa chithandizo cha kutentha, komanso zimathetsa vuto la mapindikidwe.

Gawo.2 kusankha zinthu zolondola

Kuwonongeka kwa chithandizo cha kutentha ndi kusweka kumagwirizana kwambiri ndi zitsulo zomwe zimagwiritsidwa ntchito komanso khalidwe lake, choncho ziyenera kukhazikitsidwa ndi zofunikira za nkhungu.Kusankhidwa koyenera kwachitsulo kuyenera kuganizira kulondola, kapangidwe kake ndi kukula kwa nkhungu, komanso chikhalidwe, kuchuluka ndi njira zopangira zinthu zokonzedwa.Ngati nkhungu ambiri alibe mapindikidwe ndi zofunika mwatsatanetsatane, mpweya chida zitsulo angagwiritsidwe ntchito ponena za kuchepetsa mtengo;pazigawo zopunduka mosavuta komanso zosweka, chitsulo cha aloyi chokhala ndi mphamvu zapamwamba komanso kuzimitsa kocheperako komanso kuthamanga kwa kuzizira kungagwiritsidwe ntchito;Mwachitsanzo, pakompyuta chigawo kufa poyamba ntchito T10A zitsulo, mapindikidwe lalikulu ndi zosavuta osokoneza pambuyo quenching madzi ndi mafuta kuzirala, ndi zamchere kusamba quenching patsekeke n'zosavuta kuumitsa.Tsopano gwiritsani ntchito chitsulo cha 9Mn2V kapena CrWMn chitsulo, kuuma kozimitsa ndi kusinthika kumatha kukwaniritsa zofunikira.

Zitha kuwoneka kuti pamene kusinthika kwa nkhungu yopangidwa ndi zitsulo za kaboni sikukwaniritsa zofunikira, zimakhalabe zotsika mtengo kugwiritsa ntchito zitsulo za alloy monga 9Mn2V zitsulo kapena CrWMn zitsulo.Ngakhale mtengo wazinthu ndi wokwera pang'ono, vuto la deformation ndi ming'alu limathetsedwa.

Posankha zipangizo molondola, m'pofunikanso kulimbikitsa kuyendera ndi kasamalidwe ka zipangizo kuteteza nkhungu kutentha mankhwala akulimbana chifukwa yaiwisi zolakwika.
