Iwo Mafungiro Ekutora Inofa Dhizaini

Kutambanudza Material:  

Kana izvo zvinodiwa nemutengi zvezvinhu zvisinganyanyi kunetsa, uye inodzokororwa mold miedzo ikatadza kuzadzisa zvinodiwa, unogona kuchinja kune chinhu chine yakanaka tensile zvivakwa uye edza zvakare. Chinhu chakanaka hafu yekubudirira. Nokuda kwekutambanudza, haifaniri kuregererwa. Mashizha esimbi anotonhora akakungurutswa ekudhirowa anonyanya kusanganisira 08Al, 08, 08F, 10, 15, uye simbi makumi maviri. Mari yakakura ndeye 20 simbi, iyo yakakamurwa kuita rimmed simbi uye simbi yakaurayiwa. Iyo rimmed simbi yakaderera mumutengo uye ine yakanaka yepamusoro mhando. Kusarura kwakanyanyisa uye kune tsika ye "strain kuchembera". Iyo haina kukodzera kune zvikamu zvinoda yakakwirira stamping kuita uye kutaridzika zvinodiwa. Simbi yakaurayiwa iri nani, nekuita yunifomu asi mutengo wepamusoro. Mumiririri wemhando ndeye aluminium yakaurayiwa simbi 08Al. Simbi yekune dzimwe nyika yakashandisa yeJapan SPCC-SD yakadzika yekudhirowa simbi, uye zvimiro zvayo zvekusimba zviri nani pane 08Al. Kana zvinodiwa nemutengi zvezvinhu zvisinganyanyi kunetsa, uye inodzokororwa mold miedzo ikatadza kuzadzisa zvinodiwa, vanogona kuchinja kune chimwe chinhu uye edza zvakare.

Kupera kweMold Surface.

Kana kudhirowa kwakadzika kuchiitwa, mativi maviri efa uye chisina kuvhara hachina kunyatsokwana pasi, kunyanya kana uchidhonza masimbi esimbi uye aruminiyamu mahwendefa, kudhonza mavanga kunowanzoitika, izvo zvinogona kutungamira pakukoromoka kwakasimba mumatambudziko akakomba.

Sarudzo yeKukura Kusina:  

Mamwe makwinya uye mashoma kutsemuka ndiwo musimboti wedu. Iyo blank positioning dhizaini inofanirwa kuve yakarurama. Iyo dhayamita isina chinhu yechikamu chinotenderera chekudhirowa chemuviri chine chimiro chakareruka hachizotetepe. Kunyangwe hukobvu hwezvinhu huchichinja, hwakanyanya kufanana nehupamhi hwepakutanga. Kuswedera pedyo kunogona kuverengwa zvichibva pamusimboti wekuti nzvimbo isina chinhu uye nzvimbo yechikamu chakatambanudzwa (kana kucheka kunofanira kuwedzerwa) zvakaenzana. Zvisinei, chimiro uye nzira yezvikamu zvakatambanudzwa zvinowanzooma, uye dzimwe nguva zvinoda kuderedzwa uye kutambanudza. Kunyangwe paine akawanda matatu-dimensional software inogona kuverenga iyo yakavhurwa zvinhu, kurongeka kwayo hakugone kuzadzisa zvinodiwa zve100%. 

Mhinduro: muenzaniso. Chigadzirwa chinofanirwa kupfuura nematanho akawanda, uye yekutanga maitiro anowanzo kuve maitiro asina chinhu. Chekutanga pane zvese, zvinodikanwa kuita kuverenga kwezvinhu zvakafumurwa, uye kuve nekunzwisisa kwakawanda kwechimiro uye saizi yechinhu chisina chinhu, kuitira kuti uone huwandu hwese hweiyo blanking kufa. Usagadzirise convex uye concave mold saizi ye blanking mold mushure mekugadzira mold yapera. Chekutanga shandisa tambo yekucheka kuti ugadzirise isina chinhu (kana isina chinhu ichinge yakakura, inogona kugayiwa nemuchina wekugaya wobva wasungwa). Mushure mekuedza kwakadzokororwa mune inotevera nzira yekutambanudza, saizi yeisina chinhu inozogadziriswa, uyezve iyo convex uye concave molds ye blanking die inogadziriswa. 

Chiitiko chechipiri: Pindura maitiro, tanga waedza kudhirowa kufa, uye wozogadzirisa iyo isina kuvhara saizi yeyakavharika, inova hafu yekuedza.

Tambanudza coefficient

Iyo inotambanudza coefficient ndiyo imwe yenzira huru dzemaitiro mukuverenga kwekutambanudza nzira, uye inowanzoshandiswa kugadzirisa kutevedzana uye nhamba yekutambanudza. Pane zvinhu zvakawanda zvinokanganisa kutambanudza coefficient m, zvinosanganisira zvinhu zvemukati, ukobvu hwechinyorwa, nzira yekutambanudza (zvichireva kana paine chibatiso chisina chinhu), kutambanudza nguva, kutambanudza kumhanya, convex uye concave die fillet radius, lubrication, nezvimwe. Maverengero nemisimboti yekusarudza yetensile coefficient m ndiwo mapoinzi akakosha akaunzwa muzvinyorwa zvakasiyana-siyana zvekutsikisa. Kune nzira dzakawanda dzakadai sekuverenga, kutarisa-tafura, kuverenga, nezvimwewo, uye iniwo ndinosarudza maererano nebhuku. Hapana zvitsva. Ndapota verenga bhuku racho. . 

Chiitiko chechitatu: Hukama hwehuwandu hwezvinhu, nzira yekutambanudza (inoreva kana pane chibatiso chisina chinhu), uye nhamba yekutambanudza haisi nyore kugadzirisa paunenge uchigadzirisa mold. Unofanira kungwarira!! Zvakanakisisa kutsvaga waunoshanda naye paunosarudza kutambanudza coefficient m Zvakare. 

Sarudzo yekugadzirisa mafuta yakakosha. Nzira yekusiyanisa kana mafuta ekuzora akakodzera ndipo panobviswa chigadzirwa muforoma, kana tembiricha yechigadzirwa yakanyanyisa kukwirwa nemaoko, sarudzo yemafuta ekuzora uye nzira yekukwenenzvera inofanira kutariswa, uye mafuta ekuzora anofanirwa kuiswa kune iyo mhango. , Kana kuisa bhegi remufirimu papepa. 

Chiitiko chechina: Kana uchinge wasangana nekutsemuka, shandisa mafuta ekuzora padhifa (usaise pane iyo convex kufa), uye workpiece yakafukidzwa ne 4-0.013mm firimu repurasitiki padivi refa.

Workpiece Heat Treatment 

Kunyange zvazvo isingakurudzirwi, ichiri kufanira kutaura, Panguva yekutambanudza, nekuda kwekutonhora kwepurasitiki deformation ye workpiece, kutonhora kwebasa kuoma kunoitika, kunoderedza plastiki yayo, kunowedzera deformation kuramba uye kuoma, uye mold design haina musoro. Yepakati annealing kupfavisa simbi uye kudzorera plasticity. 

Ongorora: Mukuita zvakajairika, iyo yepakati annealing haidiwi. Mushure mezvose, zvakakosha kuwedzera mari. Iwe unofanirwa kusarudza pakati pekuwedzera maitiro uye kuwedzera annealing, uye shandisa nekuchenjerera! Annealing kazhinji inotora yakaderera tembiricha annealing, kureva, recrystallization annealing. Pane zvinhu zviviri zvekuteerera kana uchinge wanyura: decarburization uye oxidation. Pano isu tinonyanya kutaura nezve oxidation. Iko kune oxide chiyero mushure mekunge workpiece yaiswa oxidized,

Pane zvipingamupinyi zviviri: kutetepa ukobvu hunoshanda hwechishandiso uye kuwedzera kupfeka mold. Kana mamiriro ekambani asipo, annealing yakajairika inowanzo shandiswa. Kuti uderedze chizvarwa che oxide chiyero, choto chinofanira kuzadzwa zvakanyanya sezvinobvira panguva yekuputira. Ndakashandisawo nzira dzevhu:  

•  -Kana paine mashoma ekushanda, anogona kusanganiswa nemamwe maworkpiece (chinodiwa: annealing process paramita dzinofanira kunge dzakafanana)
•  - Isa iyo workpiece mubhokisi resimbi uye weld iyo kuchoto. Kuti ubvise iyo oxide scale, pickling kurapwa kunofanira kuitwa maererano nemamiriro ezvinhu mushure mekuvhara. Kana mamiriro ekambani aripo, nitrogen furnace annealing inogona kushandiswa, kureva, kupenya kwakajeka. Kana ukasatarisisa, ruvara rwakada kufanana nerwakamboita annealing. 

Chiitiko chechishanu: Wedzera yepakati annealing maitiro kana uchibata nesimbi ine yakasimba inotonhora basa inoomesa kana pasina imwe nzira yekutsemura muyedzo mold.

Mapoinzi Mashoma Ekuwedzera

• 1. Ukuru pamufananidzo wechigadzirwa hunofanira kuiswa kune rumwe rutivi zvakanyanya sezvinobvira kuti zvive pachena kana ukuru hwekunze kana hukuru hwemukati hwemukati hunovimbiswa, uye zviyero zvemukati nekunze hazvigoni kuiswa panguva imwe chete. Kana mifananidzo inopiwa nevamwe ine matambudziko akadai, inofanira kutaurirwa navo. Kana vachigona kubatana, vanofanirwa kuve vakabatana. Kana vasingakwanisi kubatana, vanofanira kuziva hukama hwegungano pakati peworkpiece nezvimwe zvikamu. 
• 2. Nokuda kwemaitiro ekupedzisira, ukuru hwechishandiso chiri kunze, kufa ndiyo huru, gomba rinowanikwa nekuderedza ukuru hwepunch; hukuru hwebasa rekushanda huri mukati, punch ndiyo huru, uye gomba rinowanikwa nekuwedzera ukuru hwefa;  
• 3. Radhiyo yekona ye convex uye concave molds inofanira kugadzirwa sediki sezvinobvira kuunza nyore kune kunotevera kugadzirisa mold. 
• 4. Paunenge uchitonga chikonzero che workpiece kuputika, iwe unogona kutaurira: kuputika kunokonzerwa nehurombo hwehutsika huzhinji huzhinji hune jagged kana husina kukwana maumbirwo, uye kuputika kunokonzerwa nekugadzirisa uye mold inowanzova yakanaka.
• 5. "Mamwe wrinkles, zvishoma kuputika" Maererano nenheyo iyi, gadzirisa kuyerera kwezvinhu. Nzira idzi dzinosanganisira kugadzirisa kudzvanywa kwemubati asina chinhu, kuwedzera bhiza rekudhirowa, kucheka radius yekona ye concave uye convex mold, uye kucheka nzira yekuvhura pane workpiece.
• 6. Kuti uve nechokwadi chekusapfeka uye kudzivirira kukwenya, iyo concave-convex die holder ring inofanirwa kudzimwa. Inogona zvakare kuve yakaoma-yakavharwa, pamusoro TD kurapwa inogona zvakare kushandiswa, uye tungsten simbi inogona kushandiswa se concave uye convex molds kana zvichidikanwa.
