Iwe unoona zvakawanda zvekutaura nezve straightener shafts muwaya uye bar kugadzirisa, asi iyo chaiyo nyaya haisi mukatalogi specs. Iri muhutsvina, kutenderera kwekupisa, uye kutsauka kusinganzwisisike iwe unongoona mushure mekumhanyisa matani makumi mashanu epamusoro-kabhoni simbi. Wese munhu anotarisa pakuomarara, asi kana musimboti usina kunaka, chingori chimuti chinodhura, chinodhura chakamirira kukonzera kudzima mutsara.
Iyo Yakarasika Kusanzwisisa: Kuoma Hakusi Zvese
Kana zvitoro zvakawanda kana kunyange mamwe maOEM anoratidza a straightener shaft, yekutanga data point inogara iri pamusoro pekuoma. HRC 58, 60, pamwe yakakwirira. Chokwadi, iwe unoda iyo yekupfeka kuramba uko iyo rolls inosangana. Asi ini ndakabvisa mashafts akasangana nekuoma kweiyo asi akatadza nguva isati yakwana. Kukundikana kwanga kusiri pamusoro; kwaive kuneta kutsemuka kwakatanga about 5mm kuzasi. The material core had poor toughness. Pasi peiyo cyclic inokotama mitoro yekutwasanuka, kunyanya ine isingaenderane feedstock, ndiko kwainopa.
Apa ndipo panowanikwa kusarudzwa kwezvinhu. Haisi simbi isina tsvina kana alloy simbi. Kune shaft inoona yakanyanya kusimba kushushikana, iwe unoda kuburikidza-kuomesa giredhi ine chiyero chakanaka. Chimwe chinhu chakaita se4140 kana 4340, yakanyatsogadziriswa kupisa kuti iwane inowirirana martensitic chimiro kuburikidza nemuchinjiko-chikamu. Ndakaona zvipfeko zvichiedza kuchengetedza mutengo nesimbi yepakati kabhoni uye kungoomesa musoro kuomesa. Inoshanda, kusvikira isingaite-uye kuzorora kune njodzi, kwete zvishoma nezvishoma.
Taive necase neclient aimhanyisa high-speed wire line yespring steel. Vaidya nemumashaft mwedzi misere yega yega. Iwo ma specs aitaridzika zvakanaka pabepa. Takawana imwe yezvikamu zvavo zvakakundikana, takaita ongororo yesimbi, uye takawana musiyano wakakura mumusimboti microstructure-zviratidzo zvekudzima zvisina kunaka. Kumusoro kwaive kwakaoma, asi musimboti wacho waive wakasiyana, usina simba. Kugadzirisa kwanga kusiri chinhu chakaoma, asi nzira inodzorwa. Iyi ndiyo mhando yemakambani e nuance akafanana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) kunzwisisa kubva mumakumi emakore avo mukukanda uye kugadzira. Havasi kungocheka simbi; ivo vari kutonga iyo yose shanduko yezvinhu, iyo yakakosha kune yakasimbiswa chikamu chakadai.
Geometry & Tolerances: Apo Dzidziso Inosangana Nemuchina
Dhirowa inoda kushivirira kwakatwasuka kwe, toti, 0.05mm pamamita. Inowanikwa pane yakanaka lathe kana grinder. Asi iyo iri mukamuri yekuongorora inodzorwa nemamiriro ekunze. Muedzo chaiwo ndewokuti shaft yakabhaurirwa mufiremu yekutwasanudza, yakafanorongedzerwa, uye kupiswa kusvika 60°C nekukweshana uye ambient chirimwa kupisa. Inoramba yakatwasuka here? Kana kuti inotora seti diki?
Kushivirira kwedhayamita kwemajenari anotakura ndiyo imwe gomba rekare. Yakanyanya kusimba inokwana, uye unoisa panjodzi yekujamba panguva yekuisa kana kubatwa kubva mukupisa kwekuwedzera. Kunyanya kusununguka, uye iwe unonzwa kunetseka kupfeka, kuzunguzika, uye pakupedzisira, kuzununguka izvo zvinoparadza iko kutwasanuka. Ini ndinosarudza shanduko inodzorwa, dzimwe nguva kutotsanangura kamutobvu-mune chamfer isingawanzo kudhindwa, kuti kugadzirisa kwemunda kugoneke pasina hydraulic press uye munamato.
Ipapo ndipo panoperera. Majenari anoda kugaya zvakanaka, kazhinji kusvika 0.4 Ra kana zvirinani. Asi zvikamu pakati pezvigaro zvemupumburu? Iwe unogona kuona grooves yakagadzirwa kana kunyange kupera-kwakashanduka. Pane chikonzero. Mamiriro acho anogona kubatsira kuchengetedza lubricant uye kubvisa kupisa zvirinani pane nzvimbo yakatsetseka. Chinhu chidiki, chinoshanda chaunodzidza kubva mukuona zvikamu izvi mubasa, kwete kubva mukuzvigadzira chete.
The Manufacturing Dance: Casting vs. Machining kubva kuBar
Kumasaizi akajairwa, a straightener shaft inowanzogadzirwa kubva kune yakafogirwa kana yakakungurutswa bar stock. Zvinofanotaurwa. Asi kune madhayamita akakura, akaomesesa akakosha maficha (senge maflange kana asina kujairika counterweight maumbirwo), kana kana goho rezvinhu kuri mutengo mukuru, kukanda kunova kunonakidza. Apa ndipo panonyanya kukosha hunyanzvi hwemuchina.
A cast shaft inoda maitiro asina kukanganisa kudzivirira mukati shrinkage cavities kana inclusions iyo inova inosimudza kushushikana. Iyo mukana ndeyekuti iwe unogona kuswedera kune net chimiro, uchichengetedza yakawanda machining nguva pane kutambisa zvinhu. Izvo zvakaderera ndezvekuti iwe unofanirwa kuve uine kuomarara kusiri-kuparadza kuyedzwa (NDT). Isu takaita muyedzo makore apfuura pane yakakura-dhayamita shaft yemutsetse wemhangura tsvimbo. Takaenda nekukanda kubatanidza imba inotakura. Chinyorwa chekutanga chakapasa cheki dzese asi chakakundikana bvunzo yeultrasonic-diki, yakaungana porosity zone munzvimbo ine shear yakakwirira. Ndaifanira kuibvisa. Kuedza kwechipiri, neyakagadziridzwa gating uye dhizaini yekusimudza kubva kune foundry, yaive yakasimba.
Urwu ndirwo rudzi rwekugona kwaunotarisa kune mutengesi. Kambani yakadai QSY, ine nhoroondo refu mu shell mold casting uye Investment casting, inokwanisa kufambisa sarudzo idzi. Shell mold yakanakira simbi nesimbi zvikamu zvine kunaka kwepamusoro kupedzisa uye kurongeka kwedimensional, nepo kuisa mari kukanda kuri kweakanyanya kuoma, alloy-inorema dhizaini. Vanogona kuongorora kana shaft yakagadzirwa zviri nani kubva kune yakasimba bar pane yavo CNC machining macentre kana kana nzira yekukandira yakanyatso shanda, uye vane ruzivo rwemetallurgical kutsanangura kodzero nickel-based alloys kana cobalt-based alloys nekuda kwekupfeka kwakanyanya kana corrosion environments.
Kukundikana Modes: Iyo Nhau Shafts Taura
Unodzidza zvakawanda kubva pachikamu chakatyoka pane chakakwana. Nzvimbo yakatsemuka ibhuku renhoroondo. Kutyoka kwakachena, kwendege imwe ine mabhii emahombekombe anopenya kubva pane imwe nzvimbo? Classic kuneta kukundikana. Inotangira pane stress concentrator-pamwe kona yakapinza kumagumo kwekiyi nzira isina kutenderedzwa nemazvo, kana mudziyo waiita senge micro-crack.
Ndinoyeuka shaft yairamba ichigera kiyi yeWoodruff. Wese munhu akaramba achivandudza zvinhu zvakakosha. Pakupedzisira, takatarisa pakiyi pachayo. Yakanga yakagadzirwa neguyo remazuva ose, ichisiya pasi rakapinza, rakaenzana. Kutsemuka kwakatanga ipapo. Mhinduro yaive iri nyore rairo kune machinist: Isa radius mune iyo keyway pazasi, yakakura sekubvumidza kwedhizaini. Handina kuzombove nekumwe kukundikana. Iwo maminetsi mashanu machining dhairekitori ayo mazhinji eCAD modhi haatomboratidzi.
Kumwe kukundikana kwakajairika, kusinganzwisisike ndeye torsional wind-up. Pazvigadziro zvine ma rolls anofambiswa, shaft inotamisa torque. Kana iyo dhayamita iri pasi-yakagadzirirwa torsional mutoro, iwe unowana angular deflection. Izvi hazviputse shaft nekukasira; zvinongoita kuti nzira yekururamisa ienderane uye inoparadza unhu hwechigadzirwa. Unogona kudzingirira dambudziko kwemavhiki, uchigadzirisa kudzvanywa, usati wafunga kutarisa kana shaft pachayo iri kumonyoroka pasi pemutoro.
Kubatanidzwa & Manzwiro eShaft Yakanaka
Pakupedzisira, a straightener shaft hachisi chitsuwa. Icho chikamu chegadziriro ine mabearings, dzimba, rolls, uye muchina furemu. Iyo yakanakisa shaft inogona kudzikiswa nekusagadzikana kurongeka panguva yekuisa. Isu tinogara tichisimbisa maitiro ekuisa: shandisa alignment lasers, kwete mwero wemweya. Tarisa runout pamapoinzi akawanda pamwe nehurefu hwe shaft kana yagara mumabhenji ayo, kwete pabhenji chete.
Kune zvakare kunenge kusingabatike kunzwa kune shaft yakagadzirwa zvakanaka. Chiyero. Paunoitenderedza pakuzorora kwakatsiga usati waiswa, inofanira kutendeuka zvakanaka pasina mavara anorema. Nzvimbo yacho inofanira kunge yakachena, pasina kushandisa mitsetse yezvapupu yaunokwanisa kubata nzwara. Huremu hunofanira kunzwa hwakakodzera hukuru hwayo uye zvinhu-chiratidzo chekusimba kunoenderana, kunyanya mumhando dzakakandwa.
Vatengesi vanowana izvi ndivo vanga vari pauriri hwefekitari ivo pachavo. Vanoziva kuti chikamu chavo chinofanira kushanda munzvimbo ine tsvina, inodedera, inopisa. Haisi kungodhirowa kwavari. Paunoshanda nemumwe wako anopa zvese hunyanzvi hwekukanda hwekutendeseka kwezvinhu uye nemazvo CNC machining kune yekupedzisira kukwana uye basa - sevhisi yakasanganiswa yaungawana pane femu ine QSY's mbiri - hausi kungotenga chikamu. Iwe uri kutenga chunk yekuvimbika. Ndizvo zvinoita kuti mutsara wekugadzirisa ushande, chinja mushure mekuchinja. Chinangwa ndechekuti shaft ive chinhu chekupedzisira icho vashandi vekuchengetedza vanombofanira kufunga nezvazvo.
