Kazhinji, musoro webhaudhi unoumbwa nekutonhora musoro wepurasitiki kugadzirisa, kana uchienzaniswa nekucheka kugadzira, iyo simbi fiber (simbi yesimbi) pamwe nechimiro chechigadzirwa inoenderera, pasina kucheka pakati, iyo inovandudza kusimba kwechigadzirwa, kunyanya Kunaka kwemuchina.Cold heading forming process inosanganisira kucheka nekugadzira, kamwechete - kudzvanya, kaviri - tinya inotonhora musoro uye multi - chinzvimbo otomatiki inotonhora musoro.Muchina otomatiki unotonhora wemusoro unoshandiswa kutsika, kushungurudza, kuburitsa uye kuderedza dhayamita mumhando dzakawanda dzekugadzira. .Simplex bit kana multi-station otomatiki inotonhora musoro muchina uchishandisa maitiro ekugadzirisa eiyo yekutanga blank inogadzirwa nehukuru hwezvinhu 5 kusvika 6 metres kureba bhaa kana huremu ndeye 1900-2000 kg yehukuru hwewaya tsvimbo yesimbi waya, iyo kugadzirisa. tekinoroji ndiwo hunhu hwekutonhora musoro kuumba harisi iro rakachekwa pepa risati ravharwa, asi SHANDISA iyo otomatiki inotonhora musoro muchina pachayo nebha uye waya tsvimbo yesimbi waya.cheka uye kushatisa blank (kana zvichidiwa).Pamberi pe extrusion cavity, iyo isina chinhu inofanira kuumbwa patsva.Iyo isina chinhu inogona kuwanikwa nekuumba.Iyo blank haidi shaping isati yagumbura, kuderedza dhayamita nekutsikirira.Mushure mekunge blank yachekwa, inotumirwa kuchiteshi chebasa chinogumbura.Nhepfenyuro iyi inogona kuvandudza kunaka kwechinhu chisina chinhu, kuderedza kuumba simba rechiteshi chinotevera ne15-17%, uye kuwedzera hupenyu hwemukuvhu.Kurongeka kunowanikwa nekuumbwa kwemusoro unotonhora kunoenderanawo ne kusarudzwa kwekugadzira nzira uye nzira inoshandiswa.Mukuwedzera, zvinoenderanawo nemaitiro ekugadzirisa emidziyo inoshandiswa, maitiro ekugadzirisa uye mamiriro avo, kushandiswa kwechigadzirwa, hupenyu uye dhigirii yekupfeka.Kune high alloy simbi inoshandiswa mukutonhora musoro uye extrusion, iyo yekushanda pamusoro roughness yezvakaoma alloy die haifaniri kuva Ra = 0.2um, apo kushanda kwepamusoro kwekufa kwakadaro kunosvika kuRa = 0.025-0.050um, ine hupenyu hwepamusoro.
Iyo bhaudhi shinda inowanzogadziriswa nekutonhora maitiro, kuitira kuti sikururu isina chinhu mukati meimwe dhayamita inokungurutswa kuburikidza neshinda yeshinda (fa), uye shinda inoumbwa nekumanikidzwa kweshinda yeshinda (kufa). Inoshandiswa zvakanyanya nekuti iyo yepurasitiki streamline ye screw thread haina kugurwa, simba rinowedzerwa, kunyatsojeka kwakakwirira uye hutano huri yunifomu.Kuti ibudise tambo kunze kwedhayamita yechigadzirwa chekupedzisira, dhayamita inodiwa ye thread isina chinhu yakasiyana, nekuti inoganhurwa neshinda chaiyo, ingave iyo yekupfekedza zvinhu uye zvimwe zvinhu.Kukunguruka (kutenderedza) kudzvanya shinda inzira yekugadzira shinda mazino nepurasitiki deformation.Iyo ine shinda ine nzwi rimwechete uye conical chimiro chekukunguruka ( kukunguruka waya ndiro) kufa, rimwe divi kuti extrude cylindrical goko, rimwe divi kuita goko kutenderera, rokupedzisira kukunguruka kufa pamusoro conical chimiro kutamirwa kugoko, kuti shinda kuumba.Rolling (rub) kumanikidza shinda procEssing common point is that the number of rolling revolution haina kuwandisa, kana yakawandisa, the kunyatsoshanda yakaderera, pamusoro shinda mazino nyore kubudisa kupatsanurwa kana nhevedzano buckle phenomenon.Nekusiyana, kana nhamba marevolutions zvakare. diki, shinda dhayamita iri nyore kurasikirwa nedenderedzwa, kukunguruka kumanikidza kuwedzera kusingawanzo danho rekutanga, zvichikonzera kufa kupfupika. .Kana zviremara izvi zvikaitika muNhamba huru, zvichawanikwa muchikamu chekugadzirisa.Kana nhamba shomanana yezvinokanganisa izvi zvikaitika, nzira yekugadzira haizooni zvikanganiso izvi zvichayerera kumushandisi, zvichikonzera dambudziko.Naizvozvo, nyaya dzinokosha dze kugadzirisa mamiriro anofanirwa kupfupikiswa kudzora izvi zvakakosha zvinhu mukugadzira maitiro.
Zvisungo zvesimba zvakakwirira zvichadzikamiswa uye kudzikamiswa zvinoenderana nezvinodiwa zvehunyanzvi. Chinangwa chekurapa kwekupisa uye kupisa ndechekuvandudza yakazara ma mechanics ezvimisikidzo zvezvisungo kuti zvisangane nezvakatsanangurwa tensile simba kukosha uye kukotama simba reshiyo.Tekinoroji yekurapa kupisa ine simba rakakosha pane unhu hwemukati hwepamusoro-simba fasteners, kunyanya kunaka kwayo mukati.Nokudaro, kuitira kuti ugadzire zvigadziro zvemhando yepamusoro-soro, zvakakosha kuti tive nemhando yepamusoro yekupisa tekinoroji tekinoroji.Nekuda kwehukuru hukuru hwekugadzira uye mutengo wakaderera wemabhaudhi ane simba, pamwe chete nechimiro chakanyatsonaka uye chakanyatsojeka. the screw thread, kupisa kupisa midziyo inodiwa kuti ive nehombe yekugadzira simba, yakakwirira dhigirii ye automation uye kunaka kwehutano hwekupisa.Kubvira kuma1990, mutsara unoenderera mberi wekugadzira kupisa kwekugadzira nemhepo inodzivirira yave iri panzvimbo yakakwirira.The shock-bottom type uye net-belt furnace inonyanya kukodzera kurapwa kwekupisa uye kupisa kwemadiki uye epakati-sized fasteners.Kupisa mutsara kunze kwechoto chakavharidzirwa kushanda kwakanaka, asiwo kune mhepo yepamusoro, tembiricha, uye maitiro ekugadzirisa. Kudzora kwekombuta, kukundikana kwearamu uye mabasa ekuratidzira. Mafasteners ane simba repamusoro-soro anoitwa otomatiki kubva pakudyisa - kuchenesa - kupisa - kudzima - kuchenesa - kupisa - kuisa mavara kune offline tambo, zvinobudirira kuve nechokwadi chemhando yekupisa kupisa. The decarburization of screw thread ichaita kuti chisungiso chitange chatsika kana chikatadza kusangana nekupikiswa kwezvinodiwa zvema mechanical performance, izvo zvichaita kuti screw fastener irasikirwe nekushanda uye kupfupisa hupenyu hwesevhisi.Nekuda kweiyo raw material decarbonization, kana annealing isina kukodzera, ichaita raw material decarbonization layer yakadzika.Munguva yekudzima uye kupisa kupisa kurapwa, mamwe magasi eoxidizing ari usua.Ngura yewaya yesimbi yebhawa kana kuti yakasara pawaya mushure mekudhirowa kunotonhora inoora mushure mekupisa muchoto, ichigadzira gasi rinoita oxidizing. Steel wire surface rust, semuenzaniso, inogadzirwa ne iron carbonate uye hydroxide, mushure mekupisa kuchaputswa kuita CO ₂ neH ₂ O, nokudaro zvichiwedzera decarburization. Zvigumisiro zvinoratidza kuti decarburization degree yemedium carbon alloy steel yakakomba kupfuura iyo carbon steel, uye inokurumidza decarburization. tembiricha iri pakati pe700 ne800 madhigirii Celsius.Nekuti iyo yakabatana pamusoro pesimbi waya inoora uye inosanganiswa kuita kabhoni dhaikisaidhi uye mvura nekukurumidza pasi pemamwe mamiriro ezvinhu, kana iyo inoenderera mesh bhandi chevira gasi kutonga zvisina kukodzera, kuchaitawo kuti screw decarbonization error. Kana bhaudhi resimba repamusoro richitonhora musoro, iyo mbishi uye yakavharwa decarburizing layer haingoripo chete, asi inopfuudzwa kumusoro kweshinda,zvichikonzera kuderedzwa kwema mechanical properties (kunyanya simba uye abrasion resistance) nokuda kwepamusoro pezvigadziro zvinoda kuomeswa.Kuwedzera, iyo decarburization yepamusoro yesimbi yesimbi, pamusoro uye sangano remukati zvakasiyana uye ine zvakasiyana-siyana yekuwedzera coefficient, quenching inogona kubudisa kuputika kwepamusoro. .Naizvozvo, kudzivirira shinda pamusoro decarburization mukupisa quenching, asiwo nokuda mbishi zvinhu zvave zvine mwero coated kabhoni decarburization of fasteners, shandura zvakanakira mambure bhandi choto chinodzivirira mhepo inodzivirira munheyo yakaenzana yepakutanga kabhoni kugutsikana. uye carbon coating parts, yatove decarburization fasteners zvishoma nezvishoma kudzokera kune yepakutanga kabhoni yemukati, kabhoni inogoneka yakaiswa mu 0.42% 0.48% inokurudzirwa, nanotubes uye inodzima tembiricha yekupisa, yakafanana haigone pasi pekushisa kwepamusoro, kuitira kudzivirira zviyo zvakakora, zvinokanganisa michina. properties.The main quality problems of fasteners in quenching and quenching process are: Kudzima kuomarara hakuna kukwana;Kusaenzana kuomarara kuomarara;Kudzima deformation overshoot;Kudzima cracking.Matambudziko akadai mumunda anowanzoenderana neyakabikwa, kudzima kupisa uye kudzima kutonhora.Iko kurongeka kwakaringana kwemaitiro ekupisa kupisa uye kumira kwemaitiro ekugadzira mashandiro anogona kazhinji kudzivirira njodzi dzemhando iyi.
