1. Nyaya yeround link maketani ekuchera migodhi
Nekuwedzera kuri kuita kudiwa kwesimba remarasha muhupfumi hwenyika, michina yekuchera marasha yakasimukira nekukurumidza. Sechishandiso chikuru chemigodhi yemarasha yakazara mumugodhi wemarasha, chikamu chekutumira pane scraper conveyor chakagadzirawo nekukurumidza. Mune imwe nzira, kuvandudzwa kwe scraper conveyor kunoenderana nekuvandudzwa kwekuchera yakakwirira-yakasimba round link cheni. Kuchera yakakwirira-simba raundi yekubatanidza cheni ndicho chikamu chakakosha chetani scraper conveyor mumugodhi wemarasha. Hunhu hwayo uye kuita kwayoinokanganisa zvakananga kushanda kwemidziyo uye marasha ekubuda kwemugodhi wemarasha.
Kuvandudzwa kwemigodhi yakakwirira-yakasimba round link cheni inonyanya kusanganisa zvinotevera zvinhu: kuvandudzwa kwesimbi yezvicherwa round link cheni, kuvandudzwa kwecheni yekupisa tekinoroji, optimization yesimbi yakatenderedza yekubatanidza cheni saizi uye chimiro, akasiyana cheni dhizaini uye kuvandudzwa kweketani kugadzira tekinoroji. Nekuda kwekuvandudzwa uku, iyo mechanical zvivakwa uye kuvimbika kwekuchera round link chenidzakavandudzwa zvikuru. Izvo zvinotsanangurwa uye zvemakanika zvimiro zvecheni inogadzirwa nemamwe macheni ekugadzira mabhizinesi epasirese zvakapfuura nekure iyo yeGerman DIN 22252 chiyero chinoshandiswa zvakanyanya pasirese.
Iyo yekutanga yakaderera-giredhi simbi yekumigodhi inotenderera yekubatanidza cheni kune dzimwe nyika yainyanya kabhoni manganese simbi, ine yakaderera kabhoni yemukati, yakaderera alloy element yezvinhu, yakaderera kuoma, uye cheni dhayamita < ø 19mm. Mumakore ekuma1970, manganese nickel chromium molybdenum akatevedzana epamusoro-giredhi cheni masimbi akagadzirwa. Masimbi akajairika anosanganisira 23MnNiMoCr52, 23MnNiMoCr64, nezvimwewo simbi idzi dzine kuoma kwakanaka, weldability uye kusimba uye kusimba, uye dzakakodzera kugadzirwa kwehukuru hweC-grade cheni. 23MnNiMoCr54 simbi yakagadzirwa mukupera kwema1980. Kubva pa23MnNiMoCr64 simbi, zvinyorwa zvesilicon uye manganese zvakaderedzwa uye zvinyorwa zvechromium uye molybdenum zvakawedzerwa. Kuoma kwayo kwaive nani pane kuya kwe23MnNiMoCr64 simbi. Mumakore achangopfuura, nekuda kwekuenderera mberi kwekuvandudzwa kwezvinodiwa zveround link simbi cheni uye nekuenderera mberi kwekuwedzera kwekutsanangurwa kwecheni nekuda kwekucherwa kwemarasha mumigodhi yemarasha, mamwe makambani emaketani akagadzira mamwe magiredhi matsva esimbi, uye zvimwe zvinhu zveizvi. mamakisi matsva esimbi akakwira kupfuura 23MnNiMoCr54 simbi. Semuenzaniso, "HO" simbi yakagadziridzwa neGerman JDT kambani inogona kuwedzera simba rengetani ne15% kana ichienzaniswa ne23MnNiMoCr54 simbi.
2.Mining cheni sevhisi mamiriro uye kukundikana kuongorora
2.1 zvicherwa cheni sevhisi mamiriro
Mamiriro ebasa eround link chain ndeaya: (1) tension force; (2) Kuneta kunokonzerwa nekuputika mutoro; (3) Kupokana nekupfeka kunoitika pakati pemacheni links, cheni chinongedzo uye cheni sprockets, uye cheni chinongedzo uye epakati mahwendefa uye groove mativi; (4) Corrosion inokonzerwa nekuita kwemarasha akapwanyika, hupfu hwedombo uye mweya wakanyorova.
2.2 mugodhi cheni inobatanidza kukundikana kuongororwa
Mafomu ekupwanya ezvicherwa zvecheni zvinongedzo anogona kukamurwa kuita: (1) mutoro wecheni unodarika wakasimba wekutyoka mutoro, zvichikonzera kuputsika nguva isati yakwana. Kutyoka uku kunowanzoitika munzvimbo dzakakanganisika dzecheni yekubatanidza fudzi kana nzvimbo yakatwasuka, senge mutswe kubva kuflash butt welding kupisa kwakakanganiswa zone uye munhu bhaa zvinhu zvinotsemuka; (2) Mushure mokumhanya kwenguva yakati, mutsara wekuchera migodhi hauna kusvika pamutoro unoputika, zvichiita kuti kuputsika kunokonzerwa nekuneta. Kutyoka uku kunowanzoitika pakubatana pakati peruoko rwakatwasuka nekorona yecheni link.
Zvinodiwa zvemigodhi round link chain: (1) kuve nepamusoro kutakura mutoro pasi pechinhu chimwe chete uye chikamu; (2) kuve nepamusoro pekutyora mutoro uye kurebesa kurinani; (3) kuve nekushomeka kudiki pasi pechiito chehukuru hwekurodha kukwanisa kuve nechokwadi meshing yakanaka; (4) kuva nesimba rakanyanya kuneta; (5) kuve nekushomeka kwepamusoro; (6) kuve nekuomarara kwakanyanya uye zvirinani kunyudzwa kwemhedzisiro mutoro; (7) zviyero zvejometri kusangana nedhirowa.
3.Mining cheni yekugadzira nzira
Nzira yekugadzira yeketani yemigodhi: kucheka bhawa → kupeta nekurukwa → kubatana → kukwenenzverwa → bvunzo yekutanga yeumboo → kurapwa kupisa → yechipiri umbowo bvunzo → kuongorora. Welding uye kupisa kurapwa ndiwo akakosha maitiro mukugadzirwa kwemigodhi yeround link chain, iyo inokanganisa zvakananga kunaka kwechigadzirwa. Scientific welding parameters inogona kuvandudza goho uye kuderedza mutengo wekugadzira; zvakakodzera kupisa kupisa muitiro anogona kupa zvizere kutamba kune zvinhu zvinhu uye kunatsiridza chigadzirwa kunaka.
Kuti ive nechokwadi chekushongedza kwemhando yezvicherwa, manual arc welding uye resistance butt welding zvakabviswa. Flash butt welding inoshandiswa zvakanyanya nekuda kwemabhenefiti ayo akadai seyepamusoro dhigirii re automation, kuderera kwevashandi uye kugadzikana kwemhando yechigadzirwa.
Parizvino, kurapwa kwekupisa kwemigodhi yeround link cheni kazhinji kunotora yepakati frequency induction kupisa, kuenderera kudzima uye kupisa. Izvo zvakakosha zvepakati frequency induction kudziyisa ndeyekuti iyo molecular chimiro chechinhu chinomutswa pasi pemunda wemagetsi, mamorekuru anowana simba uye anodhumhana kugadzira kupisa. Munguva yepakati frequency induction kupisa kurapwa, iyo inductor yakabatana neyepakati frequency AC yeimwe frequency, uye cheni chinongedzo chinofamba nekumhanya yunifomu mune inductor. Nenzira iyi, iyo inokonzeresa ikozvino ine yakafanana frequency uye yakatarisana kutungamira sezvo inductor ichagadzirwa mumaketani ekubatanidza, kuitira kuti simba remagetsi rishandurwe kuita kupisa simba, uye cheni chinongedzo chinogona kudziyirwa kune tembiricha inodiwa pakudzima. uye kurarama munguva pfupi.
Medium frequency induction heat ine kukurumidza kumhanya uye kushoma oxidation. Mushure mekudzima, yakanyatso kudzima chimiro uye austenite saizi yezviyo inogona kuwanikwa, iyo inovandudza kusimba uye kuoma kweketani yekubatanidza. Panguva imwecheteyo, inewo zvakanakira hutsanana, hutsanana, kugadzirisa nyore uye kushanda kwepamusoro kwekugadzira. Muchikamu chekupisa, iyo chain link welding zone inopfuura nepamusoro pekushisa kwekushisa uye inobvisa huwandu hukuru hwekudzima kushushikana kwemukati munguva pfupi, iyo ine mhedzisiro yakakosha pakuvandudza mapurasitiki uye kuoma kwenzvimbo yewelding uye kunonoka kutanga. uye kukura kwekutsemuka. Tembiricha iri pamusoro pecheni yekubatanidza bendekete yakadzikira, uye ine kuomarara kwepamusoro mushure mekupisa, izvo zvinogoneka pakupfekwa kwecheni chinongedzo panguva yekushanda, kureva, kupfeka pakati pemacheni links uye meshing pakati pecheni. links uye chain sprocket.
4. Mhedziso
(1) Simbi yemigodhi yakakwirira-yakasimba kutenderera yekubatanidza cheni iri kusimukira munzira yekusimba kwepamusoro, kuomarara kwepamusoro, kusimba kwepurasitiki yakakwira uye kuramba kwemarara kupfuura 23MnNiMoCr54 simbi inowanzoshandiswa munyika. Parizvino, mamakisi esimbi matsva uye ane patent akaiswa.
(2) Kuvandudzwa kwema mechanical properties yemugodhi wepamusoro-simba kumativi ekubatanidza ketani inosimudzira kuenderera mberi kwekuvandudza uye kukwana kwekupisa kupisa nzira. Iko kushandiswa kunonzwisisika uye kutonga kwakaringana kwehunyanzvi hwekupisa tekinoroji ndiyo kiyi yekuvandudza michina yeketani. Mining cheni yekupisa kupisa tekinoroji yave iyo yakakosha tekinoroji yevanogadzira cheni.
(3) Saizi, chimiro uye cheni chimiro chemigodhi yakakwirira-simba raundi yekubatanidza cheni yakagadziridzwa uye yakagadziridzwa. Izvi zvinogadziriswa uye zvigadziriswe zvinogadzirwa maererano nemigumisiro yekuongorora kushushikana kweketani uye pasi pemamiriro ekuti simba remigodhi yemarasha rinoda kuwedzerwa uye nzvimbo yepasi pemugodhi wemarasha ishoma.
(4) Kuwedzera kwekutsanangurwa kwemigodhi yakakwirira-yakasimba round link cheni, shanduko yechimiro chechimiro uye kuvandudzwa kwemakanika zvivakwa zvinosimudzira kukurumidza kunoenderana kusimudzira kweyakatenderera simbi yekubatanidza cheni kugadzira michina uye tekinoroji.
