Paunonzwa 'chigadziko chesimbi', vanhu vazhinji vanofungidzira simbi yakapfava, yakapfava—huremu husinganzwisisike hwekubhaudzira muchina. Ndiyo yekutanga kusanzwisisa. Muchokwadi, chinhu chehwaro chinotanga neinjiniya, kwete kupera. Ndakaona mapurojekiti akawandisa apo nyaya dzevibration kana kupfeka nguva isati yakwana zvakadzoserwa kumashure kune hwaro hwaibatwa sekufunga kwekupedzisira. Sarudzo yezvinhu, maitiro ekukanda, mbabvu yemukati, uye machining enzvimbo dzinokwira - nhanho imwe neimwe yakakosha. Hazvisi zvekuremerwa chete; ndezvekunyanya kurema uye kunzwika kwechimiro.
Nyaya Haisi Iron Chete
Kudoma simbi yakakandwa kwakafanana nekuhodha nyama paresitorendi-hazvina kujeka kwazvo. Nokuda kwakasimba midziyo yesimbi base, isu tinowanzo kutarisa mamakisi seASTM A48 Kirasi 35 kana 40 grey iron. Iyo graphite flake chimiro mune grey iron inopa iyo yakanakisa damping kugona, inova ndiyo poindi yekunyudza kunyura. Ductile iron (ASTM A536) ndechimwe chikara, chine simba rekusimudzira zviri nani uye kumwe kuramba, asi hainyorovese mavibrations zvakare. Chisarudzo chinoenderana nemitoro ine simba. Ndinoyeuka basa remuchina wekurongedza unomhanya-mhanya apo mutengi aisimbirira paidhini resimbi kuti riwane simba. Takatozowedzera madhamupadhi anodhura nekuti base pachayo yairira sebhero. Dzimwe nguva, yechinyakare grey iron ndiyo mhinduro chaiyo yebasa racho.
Zvadaro pane alloying. Kune mabhesi munzvimbo dzakaoma - funga nzvimbo dzekugezesa makemikari kana kuisirwa kunze - unogona kutarisa Ni-Resist mhando iron. Yakasiyana mutengo bracket, asi inoramba corrosion zvirinani. Chikwata pa QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., (https://www.tsingtaocnc.com) ane ruzivo pano. Nekumashure kwavo mune alloys akakosha, ivo vanonzwisisa kuti kusarudzwa kwezvinhu ndiyo yekutanga yakakosha sarudzo. Mbiri yekambani yavo inotaura pamusoro pemakore makumi matatu ekukandira uye kugadzira, inova imhando yekugara inovaka ruzivo runoshanda nezve maitiro ezvigadzirwa izvi pauriri hwechitoro, kwete pabepa re data.
Iwe zvakare haugone kufuratira maitiro ekukanda. Kukanda kusina gedhi uye kusimudzwa kunogona kuunza kushushikana kwemukati kana kuputika maburi ayo anogona kusaoneka kusvika machining ekupedzisira apfuura, zvichiparadza chidimbu chinodhura. Shell mold casting, iyo QSY inonyanya kukoshesa, inopa kupedzisa kuri nani kwepamusoro uye kurongeka kwakaringana zvichienzaniswa nedzimwe nzira dzejecha rakasvibira. Izvi zvinoreva kushoma machining stock yekubvisa gare gare, iyo inochengetedza nguva uye inochengetedza kuvimbika kweganda rekukanda. Kune chigadziko chinoda kuchena, chaiyo geometry yekumisa tsoka nemabhaudhi mapatani, izvi zvine basa.
Dhizaini: Kunoitirwa Basa Rechokwadi
Iyo CAD modhi ndiyo iyo base inowana kuchengetedza kwayo. Haisi chivharo chakasimba. Internal ribbing ndizvo zvese-kugadzira gidhi chimiro kuti uwedzere kuoma-ku-huremu reshiyo. The trick kuisa mbabvu kunanga kuomarara parinodiwa pasina kugadzira inopisa nzvimbo panguva yekukanda izvo zvinogona kukonzera kutsemuka. Isu tinowanzo shandisa finite element analysis (FEA) ikozvino kune yakakwirira-yakakosha mabhesi, asi kuchine hunyanzvi hwekududzira mhedzisiro. Dzimwe nguva software inopa gadziriso yembabvu inotyisa kukanda kana kuchenesa. Iwe unoda mugadziri anonzwisisa zvese kuyerera kwekushushikana uye yekutanga tsika.
Imwezve tsanangudzo yaiwanzoshaikwa: iwo anokwira mapadhi. Izvi zvinoda kusimudzwa, nzvimbo dzakagadzirwa nemichina, kwete kungokanda mbishi chete. Iyo flatness uye parallelism pakati pemapads ndizvo zvinoita kuti muchina ugare chokwadi pasina kukonzeresa kushushikana. Ndanga ndiri pakuisa kwatakapedza nguva yakawanda tichipenya uye tichikuya chigadziko pane kuunganidza muchina pamusoro payo - chiratidzo chakajeka chekuti machining specs aive akasununguka kana asina kusimbiswa. Mudiwa akanaka achabata hwaro sechikamu chechokwadi. Tichitarisa kugona kweQSY, musanganiswa wavo wegoko mold/investment kukanda ne-in-house CNC machining mukana mukuru pano. Ivo vanogona kudzora maitiro kubva kusimbi yakanyungudutswa kusvika yakapedzwa machini pamusoro, izvo zvinoderedza kushivirira stack-up nyaya.
Kozotiwo zvekuwedzera: zvakaiswa shinda dzekuisa mabhaudhi, akamisikidzwa makonditi machani ewaya, kana kunyange madhiri ekudzosa anotonhodza. Kufunga nezvazvo padanho rekugadzira kwakachipa. Kuaisa mumunda nemadrills uye welders kunodhura uye zvinogona kukanganisa kukanda. Izvo ndezvekutarisira muchina wekubatanidza uye wekupedzisira-mushandisi zvinodiwa.
The Machining Handoff
Iyi ipfungwa huru yekurwadziwa. Kukandwa kunosvika pachitoro chemuchina. Kana ichibva kune mumwe mutengesi, nhanho yekutanga inowanzo tsvaga iyo datum. Iko kukanda kunogona kunge kwakashanduka kana kumonyoroka zvishoma panguva yekutonhora. Iyo yakanaka yakawanikwa inozopa inowirirana datum mapoinzi kana kutoita hutsinye hwekugadzira machining kuti uvamise. Pasina izvozvo, machinist anotanga nekufungidzira mutambo, iyo inodya mukati meiyo chaiyo yechikamu chekupedzisira.
Ichi ndicho chikonzero vatengesi vakasanganiswa vane musoro kune zvakakosha zvinhu senge midziyo yesimbi base. Kambani inobata zvese kukanda uye kugadzira, seyambotaurwa QSY, ine mhinduro loop yakavakirwa-mukati. Vagadziri vavo vanogona kuudza timu yavo yevakawana kana imwe dhizaini dhizaini ichikonzera kupfeka kwechishandiso kana kana dhizaini angle inoda hafu-dhigirii gadziriso kuti ive nani. Iko kuenderera mberi kwekuvandudza kwakaoma kutevedzera kana uchibata nevatengesi vakawanda vanopomerana mhosva.
Kutevedzana kwemuchina kwakakoshawo. Iwe unowanzo kuda kuita rough muchina, wobva warega kuti igare kutenderera kwekunetsekana (kunyanya kune mabhesi makuru), wozopedzisa muchina. Kusvetuka kuzorora kwekunetseka kunogona kutungamira kufamba mushure mekuiswa, kukanda kurongeka kunze kwehwindo. Idanho rinotora nguva iro vamwe vanoedza kupfuura kuti vachengetedze vhiki pane chirongwa, asi zvinogara zvichidhura gare gare.
Kukundikana Modes uye Zvaunodzidza
Mabhesi haawanzo kukundikana zvine njodzi; vanokundikana chinyararire kuburikidza nekusarongeka uye kudedera. Nyaya inonyanyozivikanwa yandakawana ndeye resonant vibration. Iyo base yakasarudzika frequency iri padhuze zvakanyanya kune iyo inoshanda frequency yemuchina. Inogona kupasa static mutoro bvunzo ine mavara anobhururuka, asi kana ichinge ichimhanya pa1800 RPM, gungano rese rinotanga kurira. Kugadzirisa? Dzimwe nguva kuwedzera huremu (kukanganisa chinangwa chedhizaini isina kuremerwa), dzimwe nguva kuwedzera tuned dampers, dzimwe nguva kuomesa mbabvu. Kugadzirisa kwakanakisa kuwana dhizaini kekutanga nekuongorora kwakasimba.
Corrosion imwe mhondi inononoka. Nheyo yakagara pauriri hwekongiri munzvimbo ine mwando inogona kupukuta unyoro uye ngura kubva pasi zvichikwira. Pendi chete haina kukwana. Isu tinotsanangura gadziriro yakazara yepasi-kupfurwa kuputika, ipapo yepamusoro-mhando epoxy primer uye topcoat. Nokuda kwepasi, dzimwe nguva bituminous coating inowedzerwa. Iri ibasa risina kunaka, asi rinodzivirira callbacks makore mashanu pasi pemutsara.
Kutadza kunoshamisa kwaive hwaro hwakatsemuka panguva yekufambisa. Magadzirirwo acho aive neakareba, akatetepa overhang kuti atsigire mudziyo weparutivi. Yakanga yakasimba zvakakwana kuti ishandiswe asi yaisakwanisa kubata kushushikana kwekusimudzwa nemaforklift munzvimbo dzisiridzo. Izvo zvakatidzidzisa kugadzira mumabhegi ekusimudza akazvipira kana kunyatso nyora mapoinzi akakodzera pakudhirowa uye nekukanda kwayo. Mushandisi wekupedzisira haasi muverengi wepfungwa.
Kuiputira: Iyo Base seSisitimu Chikamu
Saka, a midziyo yesimbi base iri kure nechinhu. Icho chidimbu-chakagadzirwa-chimedu chinopindirana nepasi, muchina, uye nharaunda. Kusarudza mutengesi hakusi kungowana mutengo pakirogiramu yesimbi. Zviri pamusoro peruzivo rwavo rwesimbi, dhizaini-ye-kugadzirwa kwekuisa, maitiro avo ekudzora kubva mukuumbwa kuenda kune muchina shopu, uye kunzwisisa kwavo kwekupedzisira application.
Ndosaka uchitsvaga vatambi vakamira vane vertical kusanganisa. A firm like QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. nemakumi emakore ekukanda uye kugadzira, uye kutaurwa kwakajeka kwekushanda nesimbi yakakandwa uye simbi, inomisikidzwa kubata iyo yakaoma. Ivo vanogona kunge vaona shanduko kubva kudhirowa yemanyorero kuenda ku 3D simulation uye vanonzwisisa zvinobatika zvinodikanwa kuti dhizaini inyatsoshanda musimbi.
Pakupedzisira, chinangwa ndechokuti chigadziko chive chisingaoneki. Kana pasina anozviona mushure mekuiswa-pasina ruzha rusinganzwisisike, hapana chikonzero chekugara uchigadzirisa, pasina ngura pasi - saka waita basa rako nemazvo. Inova hwaro hwakanyarara, hwakasimba zvimwe zvese zvinotsamira pazviri, ndizvo chaizvo zvazvinofanira kuva.
