Pakurovera nekupinda mukatisimbi stamping, iyo deformation nzvimbo inongogumira mukati mefillet yekufa.Pasi pechiito cheunidirectional kana bidirectional tensile stress, tangential elongation deformation yakakura kudarika radial compression deformation, zvichikonzera kudzikiswa kwezvinhu.Muromo wemupendero wakamira wegomba reflanging wakatetepa kusvika pakakwirira.Kana ukobvu hwakatetepa zvakawandisa uye kukwidziridzwa kwezvinhu kuchipfuura muganhu wekurebesa kwechinhu, iyo inonzi p fracture inoitika (kutsemuka kunokonzerwa nekurebesa kwakanyanya uye kusakwana kwepurasitiki yechinhu chinonzi force anus fracture; kutsemuka kunokonzerwa nekunyanyisa. kuumba simba uye kusakwana kwesimba rezvinhu zvinonzi fracture).Pakurovera nekukanda, iyo idiki iyo flanging coefficient K, iyo yakakura dhigirii ye deformation, uye yakakura kudzikisira ukobvu hwemuromo wakatwasuka wemuromo, zviri nyore kutsemuka.Naizvozvo, kudzikisira ukobvu hwemuromo wakatwasuka wemuromo haugone kufuratirwa kana uchibhururuka.
1.Kutsemuka kunoitika padenderedzwa rekuvhurwa kwegomba rakabhowa.Chikonzero chikuru ndechekuti iyo punched pre hole chikamu ine kubvarura kumusoro uye burr, uko kune kushushikana kwepfungwa.Munguva yekutendeuka kwegomba, plastiki yenzvimbo ino yakashata uye iri nyore kuputika.Kushandiswa kwezvinhu zvine kurebesa kwakanaka kunogona kuwedzera deformation dhigirii repunching gole flanging uye kuderedza gomba rinoputika kuputika.Kana kuumbwa kuchibvumirwa, iyo pre hole dhayamita ichawedzerwa zvakanyanya sezvinobvira kuderedza deformation yegomba, iyo inobatsira kuderedza kuputika kwegomba.Kana chimiro chichibvumira, zvinhu zvakatetepa zvichashandiswa zvakanyanya sezvinobvira kuwedzera dhayamita yakaenzana (D 0 / t) yepre hole, iyo inobatsira kuderedza mukana wekuputika kwegomba.Paunenge uchigadzira mold, zviri nani kutora parabolic kana spherical chimiro cheflanging punch, iyo inogona kuwedzera inobvumidzwa deformation yezvinhu zvemuno uye kuderedza kuputika.Panguva yekutsikirira, kutungamira kwekurovera uye kuputika kunogona kupesana neiyo yekurova uye pre drilling, kuitira kuti burr iri mukati meiyo flanging, iyo inogona kuderedza kuputika.
2. Mushure mokunge gomba rekutsika uye kuputika kwavharwa, gomba rinopera, iyo flange haina kumira, uye dhayamita yegomba inova diki, izvo zvichaita kuti zvive zvakaoma kuputira panguva yegungano.Zvikonzero zvikuru zvemitsipa ndeyezvinhu springback, uye gap z/2 pakati pe punch uye kufa rakakurisa.Izvo zvinhu zvine basa rakanaka rinoshandiswa mukugadzira, ine diki rebound, iyo inogona kuvandudza dambudziko remitsipa.Paunenge uchigadzira iyo dhizaini, kusarudza iyo yakakodzera clearance pakati pemurume nemukadzi kufa kunogona kuve nechokwadi chekuti flanging flange yakamira.Kubvisirwa pakati pe punch uye kufa kunowanzo kuderera zvishoma pane ukobvu hwezvinhu.
3. Kureba kusina kukwana kweflanging flange kunoderedza zvakananga kureba kwekutsvaira kwekona uye gomba uye kunokanganisa kuvimbika kwekubatanidza screw.Zvinhu zvinokanganisa hurefu hweflange ye stamping flanging zvinosanganisira yakawandisa pre hole dhayamita, etc. Sarudza dhayamita diki regomba rekutanga kubaya kuti uwedzere kureba kwekutenderera kwegomba.Kana iyo pre hole dhayamita isingagone kuderedzwa, iyo kutetepa uye kubhururuka kunogona kugamuchirwa kuita kuti madziro aite mutete kuti awedzere kureba kweflanging flange.
4. Mudzi R wekurovera nekuputika wakakura zvakanyanya.Mushure mekuputika, mudzi R wakakurisa, izvo zvinozoita kuti chikamu chikuru chemudzi chisasangana nescrew panguva yekuungana, kuderedza screw mukureba kwescrew uye gomba, uye kuderedza kuvimbika kweiyo screw connection.Mudzi R wegomba reflanging wakakurisa, une hukama nehupamhi hwezvinhu uye fillet yekupinda ye stamping flanging inofa.Iyo yakakora iyo zvinhu, iyo yakakura mudzi R ichave;Iyo yakakura iyo fillet pamusuwo wefa, iyo yakakura iyo R pamudzi wegomba rinoputika.Kuti uderedze mudzi R wegomba reflanging, zvinhu zvitete zvinofanirwa kusarudzwa zvakanyanya sezvinobvira.Paunenge uchigadzira iyo inofa, zvidiki zvidiki pamusuwo wechikadzi kufa zvinofanirwa kugadzirwa.Kana zvinhu zvakakora zvichishandiswa kana mafiritsi pamusuwo wemukadzi akafa ari pasi pe2 kaviri ukuru hwezvinhu, iyo flanging punch ichagadzirwa kuti iwedzere pfudzi nekuumbwa, uye mudzi R uchaumbwa pakupera kwekutsika. sitiroko, kana maitiro ekuumba achawedzerwa zvakasiyana.
5. Pakurova uye maburi ekuputira anogadziriswa nekurova uye flanging marara emarara, hapana chinopindirana chimiro chinoenderana neiyo concave kufa panguva yekurova, uye zvinhu zvacho zvinodhonzwa.Iyo punching tsvina inogona kunamatira kumucheto kwegomba, zvichikonzera kugara uchibaya tsvina.Kudengenyeka kwezvinhu zvakaraswa panguva yekutora uye kubata zviri nyore kuparadzira pamusoro pebasa rekufa kana chikamu, zvichiita kuti indentation iparadze pamusoro pechikamu, icho chinoda kugadziriswa kwemaoko, Zvakaoma kuzadzisa zvinodiwa zvekunze. mativi anofanira kugadzirwa, uye anogona kungoraswa chete, kutambisa simba revashandi nezvinhu;Izvo zvinhu zvakaraswa zvemakomba eflanging, kana akaunzwa kumusangano mukuru, zviri nyore kutema vashandisi uye zvinokanganisa screwing;Kune zvikamu zvemagetsi, zvakadai se flanging hole tsvina, zviri nyore kukonzera pfupi pfupi kana inowira muzvikamu zvemagetsi panguva yekutsvaira, izvo zvinotungamirira kumatambudziko ekuchengetedza magetsi.
