Kazhinji, musoro webhaudhi unoumbwa nekutonhora musoro wepurasitiki kugadzirisa, uchienzaniswa nekucheka kugadzirwa, 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 mune akati wandei .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 ndiyo hunhu hwekutonhora musoro kuumba harisi iro rakachekwa pepa rakavharika pachine nguva, asi SHANDISA otomatiki inotonhora musoro muchina pachayo nebhara newaya tsvimbo yesimbi waya yakachekwa uye kushatisa isina chinhu (kana zvichidikanwa).Pamberi pe extrusion mhango, iyo isina chinhu inofanira Beche riitwe patsva.Iyo blank inogona kuwanikwa nekuumba.Iyo blank haidi kuumbwa isati yagumbuka, kuderedza dhayamita nekutsikirira.Kana blank damburwa,inotumirwa kunoshungurudza chiteshi chebasa.Chiteshi ichi chinogona kuvandudza kunaka kwechisina chinhu,kuderedza kuumba simba rechiteshi chinotevera ne15-17%, uye kuwedzera hupenyu hwehutu.Kunyatsogadziriswa kunowanikwa nekutonhora musoro kuumba kunoenderanawo nekusarudzwa kwekugadzira nzira uye nzira inoshandiswa.Mukuwedzera, zvinoenderanawo ne Mamiriro ezvinhu emidziyo inoshandiswa, maitiro ekugadzirisa uye mamiriro avo, kushandiswa kwechishandiso, hupenyu uye dhigirii yekupfeka. Pamusoro pesimbi yakakwira alloy inoshandiswa mukutonhora musoro uye extrusion, iyo yekushanda pamusoro peiyo yakaoma alloy kufa haifanirwe kunge iri Ra = 0.2um, kana iyo kushanda kwepamusoro roughness yekufa kwakadaro inosvika Ra = 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 ndiro (kufa).Inoshandiswa zvakanyanya nekuti iyo yepurasitiki streamline ye screw thread haina kugurwa, simba rinowedzerwa, kunyatsojeka kwakakwirira uye unhu hwakafanana.Kuti ibudise tambo kunze kwedhayamita yechigadzirwa chekupedzisira, dhayamita inodiwa ye thread isina chinhu yakasiyana, nekuti inogumira neshinda chaiyo, ingave iyo yekupfekedza zvinhu uye zvimwe zvinhu.Kukungurutsa (kukunguruka) kudzvanya shinda inzira yekugadzira shinda mazino nepurasitiki deformation.Iyo ine shinda ine gomo 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, kuitira kuti shinda kuumba.Rolling (rub) kumanikidzwa shinda processing zvakajairika pfungwa ndiko kuti nhamba rolling chimurenga haana yakawandisa, kana yakawandisa, kunyatsoshanda yakaderera, pamusoro peshinda mazino nyore kubudisa kupatsanurwa kana nhevedzano buckle chiitiko.Kupesana, kana nhamba revolutions ishoma, shinda. dhayamita iri nyore kurasikirwa nedenderedzwa, kuumburuka kusimba kunowedzera kusiri kwemaitiro padanho rekutanga, zvichikonzera kupfupikiswa kwehupenyu hwekufa. Kukanganisa kwakajairika kweshinda inomonereka: kumwe kutsemuka kana makwara pashinda;Kusarongeka bhagi; shinda haina kutenderera.Kana izvi kukanganisa kunoitika muNhamba huru, ichawanikwa muchikamu chekugadzirisa.Kana nhamba shomanana yezvinokanganisa izvi zvikaitika, nzira yekugadzira haizocherechedzi zvikanganiso izvi zvichayerera kumushandisi, zvichikonzera dambudziko.Naizvozvo, nyaya dzinokosha dzekugadzirisa mamiriro ezvinhu dzinofanira. kupfupikiswa kudzora izvi zvakakosha zvinhu mukugadzira maitiro.
Zvisungo zvesimba zvakakwirira zvichadzikamiswa uye kudzikamiswa zvinoenderana nezvinodiwa zvehunyanzvi. Chinangwa chekurapa kupisa uye kupisa ndechekuvandudza yakazara ma mechanical zvivakwa zvezvisungo kuti zvisangane nezvakatsanangurwa tensile simba kukosha uye kukotama simba reshiyo.Tekinoroji yekurapa kupisa ine simba rakakosha pane mukati mehutano hwepamusoro-simba fasteners, kunyanya kunaka kwayo mukati. Nokudaro, kuitira kuti ugadzire zvigadziro zvemhando yepamusoro-soro, zvinofanirwa kuve nepamusoro-soro yekupisa tekinoroji tekinoroji.Nekuda kwehukuru hukuru hwekugadzira uye mutengo wakaderera wepamusoro-simba mabhaudhi, pamwe chete neyakajeka uye yakanyatso dhizaini. the screw thread, kupisa kupisa midziyo inodiwa kuti ive nehombe yekugadzira simba, yakakwirira dhigirii ye automation uye kunaka kwehutano hwekupisa.Kubvira kuma1990, iyo inoenderera mberi kupisa kupisa mutsara wekugadzira nemhepo inodzivirira yave iri munzvimbo inotonga. The shock-bottom type uye net-belt furnace inonyanya kukodzera kurapwa kwekupisa uye kupisa kwezvipfeko zviduku uye zvepakati. 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 - kudziyisa - kuchenesa - kupisa - kuisa mavara kune iyo isina tambo yeasina tambo, kunyatsoona kunaka kwekupisa kwekupisa. The decarburization of screw thread ichaita kuti chigadziriso 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.Panguva yekudzima uye kupisa kupisa kurapwa, mamwe magasi eoxidizing anowanzo kuunzwa kubva kunze kwechoto.Ngura yewaya yesimbi yebhawa kana inosara pawaya mushure mekutonhora kudhirowa inoora mushure mekupisa muchoto. , ichigadzira imwe oxidizing gasi. Steel waya pamusoro ngura, semuenzaniso, inogadzirwa nesimbi carbonate uye hydroxide, mushure mekupisa kuchaputswa kuita CO ₂ uye H ₂ O, zvichiwedzera decarburization. Zvigumisiro zvinoratidza kuti decarburization degree yepakati kabhoni alloy simbi yakakomba kupfuura iyo kabhoni simbi, uye inokurumidza decarburization tembiricha iri pakati pe700 ne800 madhigirii celsius.Nekuti icho chinonamira pamusoro pewaya yesimbi chinoora chobatanidzwa kuita kabhoni dhaikisaidhi nemvura nekukurumidza pasi pezvimwe. mamiriro, kana iyo inoenderera mesh bhandi chevira gasi kutonga isina kukodzera, zvakare ichakonzera screw decarbonization kukanganisa.Kana yakakwirira-simba bhaudhi inotonhora musoro, iyo mbishi uye annealed decarburizing layer haingoripo chete, asi yakawedzerwa kune iyo kumusoro kweshinda, zvichikonzera kuderedzwa kwema mechanical properties (kunyanya simba uye abrasion resistance) nokuda kwepamusoro pezvigadziro zvinoda kuomeswa.Kuwedzera, iyo yepamusoro decarburization yesimbi wire, pamusoro uye sangano remukati zvakasiyana uye zvine zvakasiyana-siyana zvekuwedzera coefficient, Kudzima kunogona kuburitsa kutsemuka kwepamusoro. Naizvozvo, kuchengetedza shinda kumusoro kwe decarburization mukupisa kupisa, asiwo kune mbishi zvinhu zvave zvine mwero coated kabhoni decarburization of fasteners, shandura mukana weiyo mesh bhandi choto chekudzivirira mumhepo yakaenzana. kune yepakutanga kabhoni yemukati uye kabhoni coating zvikamu, zvatove decarburization fasteners zvishoma nezvishoma kudzokera kune yepakutanga kabhoni yemukati, kabhoni inogoneka yakaiswa mu 0.42% 0.48% inokurudzirwa, nanotubes uye inodzima tembiricha yekudziya, yakafanana haigone pasi pekushisa kwepamusoro, kuitira kudzivirira kukomba. zviyo, zvinokanganisa mashandiro emuchina.Matambudziko makuru emhando yezvisungo mukudzima nekudzima maitiro ndeaya: kudzima kuomarara hakuna kukwana;Kusaenzana kuomarara kuomarara;Kudzima deformation overshoot;Kudzima kutsemuka.Matambudziko akadai mumunda anowanzoenderana nemidziyo, kudzima kupisa. uye kudzima kutonhora. Iko kurongeka kwakaringana kwemaitiro ekupisa kupisa uye kumira kwemaitiro ekugadzira mashandiro anogona kazhinji kudzivirira njodzi dzemhando iyi.
